Nguyen, sp. nov. Introduction Fungi are well-known as a large and diverse group of microorganisms that play important functional roles from agricultural, ecological and economic perspectives. They are crucial to natural ecosystems as decomposers degrading dead organic materials, accelerating rock weathering and response to plant growth, nutrient cycling, as well as maintaining plant diversity (Kendrick 2000; Finlay 2008; Zechmeister-Boltenstern et al. 2015; Drinkwater et al. 2017; Horwath 2017; Hyde et al. 2018a, b; Willis 2018). They are heterotrophic and may change their lifestyles from endophytic to pathogenic to saprobic on plants or other organisms as well as other fungi depending on the environmental circumstances (Hyde et al. 2007, 2018a; Promputtha et al. 2007, 2010; Slippers and Wingfield 2007; Ghimire and Hyde 2008; Hyde and Soytong 2008; Gomes et al. 2013; Zhan et al. 2016; Ariyawansa et al. 2018; Haelewaters et al. 2018; Liyanage et al. 2018; Lofgren et al. 2018; Wang et al. 2018; Sun et al. 2019). Sixteen phyla are accepted in the Kingdom Fungi (Tedersoo et al. 2018; Wijayawardene et al. 2018b). Hawksworth (1991, 2001) estimated 1.5 million species of fungi worldwide, with fewer than 5–10% having been described. Hawksworth and Lücking (2017) attempted to derive an updated estimate of global fungal diversity based on scientific evidence such as the extrapolations of plant/fungus ratios, including molecular and fieldwork data from the same sites. They concluded that there is an estimated 2.2–3.8 million undescribed species with taxa awaiting discovery in biodiversity hot spots, with only 120,000 species described and accepted (Hawksworth and Lücking 2017). In our ongoing research compiling notes on new fungal taxa, reference specimens, new data, and other taxonomic contributions, more than 900 species have been introduced, re-circumscribed and illustrated worldwide based up on morphological characteristics and phylogenetic analyses. This is the ninth paper in the fungal diversity series with more than 100 species contributions which were mainly collected from China, some other Asian countries, as well as other parts of the world. Materials and methods Materials and methods follow the previous fungal diversity notes (Hyde et al. 2016; Tibpromma et al. 2017). Fresh and dried specimens in this study were collected from Australia, 123 Brazil, Chile, China, Croatia, Equatorial Guinea, India, Italy, Korea, New Zealand, Russia, Saudi Arabia, Taiwan, Thailand, UK and the USA. Media agar used to cultivated fungi is shown in Table 1. The genes and primers used in this study are shown in the Table 2. Phylogenetic analyses were performed based on Bayesian inference (BI), maximum likelihood (ML) and maximum parsimony (MP) (see Table 2). Phylum Ascomycota R.H. Whittaker We follow the latest treatments and updated accounts of Ascomycota in Wijayawardene et al. (2017a, 2018a). Class Dothideomycetes O.E. Erikss. & Winka The Classification of families in Dothideomycetes follow Hyde et al. (2013), Liu et al. (2017a) and Wijayawardene et al. (2018a). The subclasses, orders and families of Dothideomycetes are listed in alphabetical order. Subclass Dothideomycetidae P.M. Kirk Capnodiales Woron. Teratosphaeriaceae Crous & U. Braun Teratosphaeriaceae was introduced by Crous et al. (2007a) and is typified by Teratosphaeria Syd. & P. Syd. The family was introduced to accommodate several important leaf spot and extremotolerant species initially included in the genera Teratosphaeria, Mycosphaerella and related asexual morph genera. Recently, 59 genera were listed in this family (Wijayawardene et al. 2018a). The latest treatments of genera in Teratosphaeriaceae were outlined in Quaedvlieg et al. (2014), Wäli et al.

The genus is characterized by white, septate, smooth-walled, hyaline to subhyaline mycelial hyphae often form hyphal tufts from which straight, unbranched, light brown, smooth-walled, and septate conidiophores arise laterally. Subhyaline, cuneiform, smooth-walled conidia are produced on characteristic integrated, pale brown and minutely verruculose conidiogenous cells forming apical whorls (1–5) of conidiogenous cells with inconspicuous conidial scars (Shivas et al. 2016). In this study, a new species, H. indica is introduced, which was collected as a saprobe associated with leaves of Shorea robusta Roth colonized by black moulds in India. Phylogenetic analysis from maximum likelihood based on a combined LSU and ITS sequence dataset (Fig. 1) is provided to clarify its phylogenetic affinities within Teratosphaeriaceae. Hyweljonesia indica P.N. Singh & S.K. Singh, sp. nov. MycoBank number: MB821804; Facesoffungi number: FoF03526, Fig. 2 Etymology: The specific epithet ‘‘indica’’ refers to the country of origin. Holotype: AMH 9889 Colour codes follow: Methuen Handbook of Colour (Kornerup and Wanscher 1978). Saprobic on leaves of Shorea robusta (Dipterocarpaceae) forests in terrestrial habitats. Sexual morph Undetermined. Asexual morph Vegetative hyphae smooth-walled, septate, subhyaline to light olivaceous, up to 4 lm wide. Conidiophores arising from loose to References compact hyphal tufts, macronematous, lateral, unbranched to rarely branched at base, 0–1-septate, straight, smoothwalled, light olivaceous, 4.5–24.5 lm long ( x = 9.6 lm, n = 30); base flared, 3.5–8.5 lm wide ( x = 5.87 lm, n = 30); apex narrow, cylindrical, 1.5–4.5 lm wide ( x = 2.74 lm, n = 30). Conidiogenous cells terminal, 1(– 2), straight, smooth-walled, subhyaline to olivaceous, cylindrical to clavate, scars inconspicuous, 5.5–12.8 9 2– 5 lm ( x = 10.3 9 3.28 lm, n = 30). Conidia acrogenous to rarely acropleurogenous, produced in apical whorl of 1– 12 conidia, simple, aseptate, obovoid to pyriform, smoothwalled, hyaline, apex rounded, base truncate, hilum refractive, 2.4–6.8 9 1.5–2.6 lm ( x = 4.6 9 2 lm, n = 30). Culture characteristics: Colonies on PDA reaching average 12.5 mm diam. in 12 days, after 2 weeks of incubation at 25 °C, colonies were circular, margin regular, smooth, and orange white (6A2). Later turning to grey (2C1), mucoid, centre raised, umbonate, periphery white (6A1), with abundant hyphal tufts, sulcate, up to 7500 9 132–220 lm.

Singh, AMH 9889 (holotype), ex-type living culture, NFCCI 4146 (National Fungal Culture Collection of India-WDCM 932). GenBank numbers: ITS = MF322773, LSU = MF322775. Notes: Detail study of in vitro cultural characteristics and morphology revealed a few morphological similarities with Hyweljonesia queenslandica. However, H. indica is distinct in having obovoid to pyriform conidia which are significantly larger when compared to the cuneiform 123 Fungal Diversity conidia of H. queenslandica (Fig. 2). Conidiogenous cells of H. indica mostly arise singly from the conidiophores, while they are produced in 1–5 whorls of H. queenslandica (Shivas et al. 2016). Sequence analysis of ITS and LSU positions Hyweljonesia indica in the genus Hyweljonesia closely related to H. queenslandica with strong bootstrap support (100% ML; Fig. 1). The BLASTn search of ITS sequence shows 95% similarity (468/491) with H. queenslandica (BRIP 61322b) and same similarity was recorded for LSU sequence with 98% similarity (838/851). Thus following the guidelines of Jeewon and Hyde (2016) this is a new species. To our understanding this genus and species is isolated and reported for the first time from India as a saprobic black mold associated with leaves of Shorea robusta. Subclass Pleosporomycetidae C.L.

(2016), Wang et al. (2016), Hyde et al. (2017), Tibpromma et al. (2018) and Yang et al. (2018b). Recently, 12 genera were listed in this family (Wijayawardene et al. 2018a). Dictyocheirospora M.J. D’souza et al. Dictyocheirospora was introduced by Boonmee et al. (2016) with D. rotunda M.J. D’souza et al. as the type species. Boonmee et al. (2016) included Dictyocheirospora in the new family Dictyosporiaceae based on the fact that Dictyocheirospora species have dark sporodochial colonies, and produce aeroaquatic cheiroid dictyospores. Many species were subsequently accommodated in this genus (Wang et al. 2016; Hyde et al. 2017; Tibpromma et al. 2018; Yang et al. 2018b) and 17 species are listed in Index Fungorum (2019). In this study, Dictyocheirospora metroxylonis Konta & K.D. Hyde, sp. nov. is introduced from dead Metroxylon sagu (Arecaceae) in Thailand based on morphological and multigene phylogenetic support.

Sexual morph Undetermined. Asexual morph Hyphomycetous. Sporodochia on natural substrate in small groups, punctiform, 100–200 lm diam. ( x = 130 lm, n = 10), velvety, greyish 123 Fungal Diversity to dark brown. Mycelium immersed, composed of brown, smooth, thin-walled, septate, branched hyphae. Conidiophores micronematous, pale brown, smooth, thin-walled. Conidiogenous cells 3–8 9 3–5 lm ( x = 5.2 9 4.6 lm, n = 10), holoblastic, integrated, terminal, determinate, pale brown, smooth-walled. Conidia 45–69 9 15–29 lm ( x = 61 9 20 lm, n = 20), solitary, monoblastic, acrogenous, cheiroid, pale brown, consisting of 4–6 rows of cells, rows digitate, cylindrical, inwardly curved at the tip, arising from a basal cell, each arm composed of 9–14 cells, distoseptate, constricted at thr septa, large guttule in each central cell. Conidial arm 29–58 9 5–7 lm ( x = 47 9 6 lm, n = 10) (Fig. 3). Culture characteristics: Conidia germinated on MEA within 24 h and germ tubes produced from the basal cells of the conidium. Colonies on MEA reaching 7–7.5 cm diam. after 2 weeks, at 25–28 °C, initially white, becoming grey-light brown, not sporulating on media. Material examined: THAILAND, Krabi Province, on dead Metroxylon sagu Rottb. (Arecaceae), 8 December 2014, S. Konta, KBR04d (MFLU 15-0028, holotype), extype living culture, MFLUCC 15-0282. GenBank numbers: ITS = MH742321, LSU = MH742313, SSU = MH742317, (MFLUCC 15-0282a); ITS = MH742322, LSU = MH742314, SSU = MH742318, TEF1-a = MH764301 (MFLUCC 15-0282b); ITS = MH742323, LSU = MH742315, SSU = MH742319, TEF1-a = MH764302 (MFLUCC 15-0282c); ITS = MH742324, LSU = MH742316, SSU = MH742320, TEF1-a = MH764303 (MFLUCC 15-0282d). Notes: Dictyocheirospora metroxylonis differs from other Dictyocheirospora species by its conidial size, and number of rows and cell numbers in each row. Phylogenetic analyses of a combined ITS, LSU, SSU and TEF1-a sequence dataset (Fig. 3) show that D. metroxylonis forms a distinct lineage, clustered with other Dictyocheirospora species with moderate support in ML analysis (84% ML) and high support in BI analysis (0.99 BYPP). Since Dictyocheirospora has been introduced in Dictyosporiaceae (Dothideomycetes), many species were subsequently introduced to this genus with morphological and phylogenetic evidence. Interestingly, D. metroxylonis strain MFLUCC 150282d formed a clear zone against contaminated fungi on MEA during our experiment (Fig. 4, r). Didymosphaeriaceae Munk We follow the latest treatment and updated accounts of Didymosphaeriaceae in Ariyawansa et al. (2014), Wanasinghe et al. (2018) and Tibpromma et al. (2018). There are 26 genera accepted in Didymosphaeriaceae (Wijayawardene et al. 2018a). Here we introduce a monotypic genus Vicosamyces. 123 Vicosamyces Firmino, A.R. Machado & O.L. Pereira, gen. nov. MycoBank number: MB822577; Facesoffungi number: FoF03786 Etymology: The generic epithet ‘‘Vicosamyces’’ refers to the city ‘‘Viçosa’’, where the type was collected. Biotrophic or necrotrophic associated with plant disease on living leaves, forming a large, irregular, slightly raised, rough, orange brown wound, with orange margin. Sexual morph Ascomata immersed in orange brown wound tissue, solitary, brown, globose to pyriform, ostiolate. Peridium thin-walled, composed of dark brown, pseudoparenchymatous cells, of textura angularis to textura prismatica. Hamathecium comprising numerous, cylindrical, filiform, septate, unbranched, hyaline pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical, subsessile to short pedicellate, with furcate pedicel, apically rounded with well-developed ocular chamber. Ascospores overlapping 1–2-seriate, brown, 2-celled, apiosporous, smaller at the lower cell, subfusoid to clavate, or obovoid, narrower towards the lower cell. Asexual morph Undetermined. Type species: Vicosamyces venturisporus Firmino, A.R. Machado & O.L. Pereira Notes: Vicosamyces is introduced as a new genus based on morphology and phylogenetic support (LSU and ITS sequence dataset). Phylogenetic analysis of a combined LSU and ITS sequence dataset (Fig. 5) shows the fungus belongs to Didymosphaeriaceae, clustering with the genus Austropleospora R.G. Shivas & L. Morin. Vicosamyces has 2-celled, apiospores, while, Austropleospora has muriform ascospores (Morin et al. 2010; Thambugala et al. 2014; Ariyawansa et al. 2015a). Both genera have been found as biotrophic or necrotrophic pathogens associated with plant disease on living leaves, or stems. However, these two genera are associated with different symptoms on the host tissue. Austropleospora forms subglobose ascomata, solitary or in groups, immersed in small, brown, raised necrotic spots on Chrysanthemoides monilifera ssp. rotundata (Asteraceae) (Morin et al. 2010; Thambugala et al. 2014). Vicosamyces forms globose to pyriform ascomata, solitary, immersed in large, orange-brown wound, with orange margin on leaves of Eugenia sp. (Myrtaceae). In this study, the phylogenetic relationship of Austropleospora and Vicosamyces was not well-resolved. Phylogenetic analysis obtained from more informative genes will provide a better phylogenetic relationship of these genera. Vicosamyces venturisporus Firmino, A.R. Machado & O.L. Pereira, sp. nov.

Taxa of Pleosporaceae (Pleosporales) were selected as the outgroup. Bayesian posterior probabilities (BYPP) represented by percentage equal or greater than 50% are shown above the nodes. The new isolates are in blue, ex-type strains are in bold 123 Fungal Diversity TEF1-a sequence dataset, two novel species, Keissleriella caraganae and Murilentithecium lonicerae are introduced. In addition, Phragmocamarosporium hederae Wijayaw. et al. associated with leaf spots on Cycas sp. (Cycadaceae) is reported in Yunnan, China for the first time. Keissleriella Höhn We follow the latest treatment and updated accounts of Keissleriella in Wanasinghe et al. (2018). Although 43 epithets of Keissleriella are listed in Index Fungorum (2018), only 19 species have been confirmed in Lentitheciaceae based on molecular data (Fig. 7). Keissleriella caraganae Chaiwan, Phookamsak, Wanas. & K.D. Hyde, sp. nov. Index Fungorum number: IF555523; Facesoffungi number: FoF04965, Fig. 8 Etymology: The specific epithet ‘‘caraganae’’ refers to the host genus Caragana, from which the holotype was collected. Holotype: KUN-HKAS 102236 Saprobic on Caragana arborescens (Fabaceae). Sexual morph Ascomata 140–175 lm high, 170–235 lm diam., scattered, solitary or in groups, semi-immersed, visible as raised, black dots on host surface, globose to subglobose, Fig. 6 Vicosamyces venturisporus (VIC 44320, holotype). a, b Symptoms on naturally infected leaf. c Globose to pyriform pseudothecium immersed in the leaf tissue. d Immature ascus. 123 glabrous, ostiolate at centre, with minute papilla, filled with short, brown, aseptate periphyses. Peridium 15–25 lm wide, thin-walled, of equal thickness, composed of several layers of small, flattened, brown to dark brown pseudoparenchymatous cells, arranged in a textura angularis to textura prismatica, intermixed with the host cells. Hamathecium composed of dense, 2–3 lm wide, broad filamentous, distinctly septate, anastomosed pseudoparaphyses, embedded in a hyaline gelatinous matrix. Asci 39–75 9 10–12 lm ( x = 60.1 9 11.1 lm, n = 20), 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-clavate, short pedicellate, apically rounded, with well-developed ocular chamber. Ascospores 14–20 9 3–7 lm ( x = 16.9 9 5.1 lm, n = 20), overlapping 1–2-seriate, pale yellowish, fusiform to ellipsoidal, with rounded ends, (1– )3(–4)-septate, slightly constricted at the central septum, smooth-walled, with small guttules, surrunded by a distinct mucilaginous sheath. Asexual morph Undetermined. Culture characteristics: Colonies on PDA reaching 22–29 mm diam. after 1 week at 20–25 °C, colony from above, white to cream at the margin, greenish grey in the centre; from below, white to cream at the margin, greenish grey in the centre; medium dense, circular, slightly raised, e Mature ascus. f Immature ascospore. g Brown and smooth-walled ascospores.

Material examined: CHINA, Yunnan Province, Kunming Institute of Botany, on dead hanging branch of Caragana arborescens Lam. (Fabaceae), 2 November 2017, R. Phookamsak, KIB018 (KUN-HKAS 102236, holotype), ex-type living culture, KUMCC 18-0163 = MFLUCC 18-0682 (KIB018A), KUMCC 18-0164 (KIB018B). GenBank numbers: ITS = MK214368, LSU = MK214371, SSU = MK214374, TEF1-a = MK214377 (KUMCC 18-0163); ITS = MK359434, LSU = MK359439, SSU = MK359444 TEF1-a = MK359073 (KUMCC 18-0164). Notes: Keissleriella caraganae is similar to other Keissleriella species in having ascomata with an ostiolar neck, filled with short, brown, aseptate periphyses, bitunicate, broadly cylindrical to cylindric-clavate asci and septate ascospores, surrounded by distinct mucilaginous sheath (Tanaka et al. 2015; Wanasinghe et al. 2018). Multigene phylogenetic analyses (Fig. 7) show that K. caraganae is sister to K. yonaguniensis Kaz. Tanaka & K. Hiray. (KT2604). Although it clusters with other species of Keissleriella and Pleurophoma Höhn. the clade is not wellresolved agreeing with previous studies (Tibpromma et al. 2017; Hyde et al. 2018b; Wanasinghe et al. 2018). Keissleriella caraganae has ellipsoidal to fusiform, pale yellowish, 3-septate ascospores, whereas K. yonaguniensis has cylindrical, yellowish, 5-septate ascospores, with rounded ends (Tanaka et al. 2015). Both K. caraganae and K. rosacearum Phukhams. et al. (MFLU 15-1044) have fusiform, pale yellowish, 3-septate ascospores, but K. rosacearum was collected from Rosa canina L. (Rosaceae) in Italy (Wanasinghe et al. 2018). Multigene phylogenetic analysis (Fig. 7) shows that these two species form distinct lineages in different clades. Murilentithecium Wanas. et al. We follow the latest treatment and updated accounts of Murilentithecium in Wanasinghe et al. (2018). Generic notes were also provided by Wanasinghe et al. (2014a). Three species (including our new species) are presently included in this genus viz. M. clematidis Wanas. et al., M. lonicerae (in this study) and M. rosae Phukhams. et al. (Index Fungorum 2019). These three species were collected from Clematis vitalba L. (Italy), Lonicera maackii (Rupr.) Maxim (Yunnan, China) and Rosa canina L. (Italy).

Conidiogenous cells 8–15 9 (3–)4–8 lm ( x = 11 9 5.5 lm, n = 35), enteroblastic, phialidic, rarely annellidic, discrete, determinate, hyaline, smooth, aseptate, cylindrical to doliiform, with narrow channel, minute collarette and periclinal wall thickening, arising from the inner cavity of pycnidial wall. Conidia (13.5–)14–17(–18.5) 9 7–10(–12) lm ( x = 15.6 9 9.4 lm, n = 50), initially light brown to pale yellowish, aseptate, becoming reddish brown to dark brown, muriform, subglobose to obovoid, or turbinate, with truncate base, (1–)2–4 transverse septa, with several longitudinal sectors, not constricted at the septa, smoothwalled with minute guttules. Culture characteristics: Colonies on PDA reaching 30–35 mm diam. after 3 weeks at 20–25 °C; colony from above, white-grey at the margin, grey at the centre; from below, white-grey at the margin, grey to dark grey at the centre, slightly radiated outwards colony; dense, circular, slightly raised to umbonate, surface smooth, with edge entire, floccose; not producing pigmentation in agar.

Related sequences were obtained from Wanasinghe et al. (2018). Eighty-three strains are included in the combined sequence analyses, which comprise 3419 characters with gaps. Single gene analyses were also performed and topology and clade stability compared from combined gene analyses. Massarina cisti (CBS 266.62) and M. eburnea (CBS 473.64, H3953) were used as the outgroup taxa. Bootstrap support value for ML equal to or greater than 60% and Bayesian posterior probabilities equal to or greater than 0.95 BYPP are given above the nodes. Newly generated sequences are in blue. Type strains are in bold with truncate base, (1–)2–4 transverse septa, with several longitudinal sectors. Murilentithecium clematidis has pale brown to brown, oblong to clavate conidia, with 3–5 transverse septa, and 2–5 longitudinal septa (Wanasinghe et al. 2014a; Wijayawardene et al. 2016). Murilentithecium rosae has yellowish brown to dark brown, ovoid conidia, with 3 transverse septa, and 1–2 longitudinal septa (Wanasinghe et al. 2018).

Phragmocamarosporium Wijayaw. et al. We follow the latest treatment and updated accounts of Phragmocamarosporium in Wanasinghe et al. (2018). There are only three species in this genus, P. hederae, P. platani Wijayaw. et al. and P. rosae Wanas. et al. Phragmocamarosporium hederae and P. rosae were collected from Hedera helix L. and Rosa canina in Europe (Germany and Great Britain respectively). Whereas, P. platani was found on Platanus sp. in Asia (Guizhou, China). In this study, P. hederae is reported from China on a different host. Phragmocamarosporium hederae Wijayaw., R.K.

Phookamsak, KIB020 (KUN-HKAS 102237), living culture, KUMCC 18-0165 (KIB020A), MFLUCC 18-0677 = KUMCC 18-0166 (KIB020B). Known hosts and distribution: Hedera helix L. (Araliaceae; Germany) and associated with leaf spots on Cycas (Yunnan Province, China) (Wijayawardene et al. 2015 and this study). GenBank numbers: ITS = MK214369, LSU = MK214372, SSU = MK214375, TEF1-a = MK214378 (KUMCC 18-0165); ITS = MK359434, LSU = MK359439, SSU = MK359444, TEF1-a = MK359073 (KUMCC 18-0166). Notes: Multigene phylogenetic analyses (Fig. 7) show that the strain MFLUCC 18-0677 grouped with Phragmocamarosporium hederae and P. platani in Lentitheciaceae. A BLASTn search of LSU and SSU sequence data indicates that MFLUCC 18-0677 is identical to P. hederae (100% and 99% similarities, respectively). We therefore, identify our isolate as P. hederae and this species was collected from Cycas in China for the first time. Our new isolate is similar to P. hederae in having phragmosporous conidia. Whearas, P. platani has phragmosporous and muriform conidia at maturity (Wijayawardene et al. 2015). Compared to the type of P. hederae our new isolate has shorter and broader conidiogenous cells (8–10 9 1.5–2.5 lm in the type collection) and longer conidia (9–11 9 3–4.5 lm in the type collection). Phragmocamarosporium platani has smaller conidiogenous cells (1.5–3 9 1.5–2.5 lm) and narrower conidia (12–13 9 5–7.5 lm) (Wijayawardene et al. 2015). Only LSU and SSU sequence data for P. hederae and P. platani are available in GenBank, and sequences of more informative genes are needed to clarify species in this genus. Leptosphaeriaceae M.E. Barr Leptosphaeriaceae was introduced by Barr (1987) and is typified by Leptosphaeria Ces. & De Not. to accommodate species having immersed, subglobose, thick-walled ascomata containing interascal filamentous pseudoparaphyses, with bitunicate, broad asci bearing fusiform, transversely septate, hyaline to yellow-brown ascospores and coelomycetous asexual morphs in the order Pleosporales (Ariyawansa et al. 2015b). Ariyawansa et al. (2015b) recircumscribed the genera in Leptosphaeriaceae based on morphological characteristics and multigene phylogenetic analyses, and accepted ten genera with more than 140 species. This is in agreement of the taxonomic outline of Ascomycota, provided by Wijayawardene et al. (2018a) and the notes of each genus in this family were provided by Ariyawansa et al. (2015b) and Wijayawardene et al. (2017a). We follow the latest treatment of Leptosphaeriaceae in Ariyawansa et al. (2015b) and updated accounts of taxa in Leptosphaeriaceae in Hyde et al. (2016, 2017), Tennakoon et al. (2017) and Tibpromma et al. (2017). In this paper, we introduce four new species, Leptosphaeria urticae, Plenodomus artemisiae, P. lijiangensis and Sphaerellopsis isthmospora in Leptosphaeriaceae. The asexual morph of Plenodomus sinensis is also introduced from a fern in China and a new host record of Sphaerellopsis paraphysata associated with rust on living leaves of Liriope spicata (Thunb.) Lour (Asparagaceae) is reported. Leptosphaeria Ces. & De Not. Leptosphaeria was introduced by Cesati and De Notaris (1863) and is typified by L. doliolum (Pers.) Ces. & De Not. (lectotype designated by Shearer et al. 1990). The genus is characterized by semi-immersed to erumpent, coriaceous ascomata, which become superficial, a thick-walled peridium composed of scleroplectenchymatous cells, cylindrical to cylindric-clavate asci, reddish to yellowish brown, ellipsoidal to fusiform, septate ascospores and coelomycetous coniothyrium-like and phoma-like asexual morphs (Ariyawansa et al. 2015b; Dayarathne et al. 2015). Taxonomic revision of the genus was discussed in Ariyawansa et al. (2015b). Over 1600 epithets are listed for Leptosphaeria (Index Fungorum 2019), but few species have been confirmed by phylogenetic analysis. Most Leptosphaeria species lack molecular data to clarify their phylogenetic placements. Some other Leptosphaeria sensu lato species have been treated in different genera in Leptosphaeriaceae and other related families (de Gruyter et al. 2013; Ariyawansa et al. 2015b). Leptosphaeria urticae D. Pem, E.B.G. Jones & K.D. Hyde, sp. nov.

Asci 60–140 9 9–11 lm ( x = 104.5 9 10 lm, n = 20), 8-spored, bitunicate, fissitunicate, cylindrical, rounded at the apex, pedicellate, numerous, with ocular chamber. Ascospores 35–40 9 4– 6 lm ( x = 38.3 9 5.2 lm, n = 20), overlapping 1–2-seriate, initially hyaline, becoming yellowish brown at maturity, long fusiform, (8–)9-septate, constricted at the septa, narrowly rounded at both ends, smooth-walled, lacking a mucilaginous sheath. Asexual morph Undetermined. Culture characteristics: Ascospores germinating on MEA within 24 h. Colonies growing on MEA reaching 2 cm diam. in one week at 16 °C. Mycelium superficial, surface smooth, irregular, slightly raised, edge crenate, velutinous, from above white to pale yellow, reverse yellow. Material examined: UK, Sussex, Singleton, on dead stem of Urtica dioica L. (Urticaceae), 5 April 2017, E.B Gareth Jones, 353 UK (MFLU 18-0591, holotype), ex-type living culture MFLUCC 17-2302. GenBank numbers: ITS = MK123333, LSU = MK123332, SSU = MK123329, TEF1-a = MH028391. Notes: Phylogenetic analyses of a combined LSU, SSU and ITS sequence dataset (Fig. 12) reveal that Leptosphaeria urticae (MFLU 18-0591) is sister to L. italica Dayar. et al. (MFLU 15-0174). Leptosphaeria urticae differs from L. italica in having longer asci (L. urticae, 60–140 9 9–11 lm versus 60–112 9 7–12 lm, L. italica), longer ascospores (L. urticae, 35–40 9 4–6 lm 123 Fungal Diversity versus 12–18 9 4–6 lm, L. italica) and more ascospore septation (L. urticae, (8–)9-septate versus 3-septate, L. italica) (Dayarathne et al. 2015). Based on the NCBI BLASTn search of ITS sequence data, L. urticae has 96% similarity with L. sclerotioides (Preuss ex Sacc.) Gruyter et al. However, the two species cannot be compared as L. urticae is represented only by its sexual morph, whereas, L. sclerotioides is known only by its asexual morph (de Gruyter et al. 2013). Phylogenetic analysis indicates that these two species are not conspecific. Hence, we introduce L. urticae as a new species based on both morphological and molecular data. Five Leptosphaeria species have been reported from Urtica: L. acuta (Fuckel) P. Karst., L. acutiuscula Berl., L. atropurpurea Petr., L. doliolum (Pers.) Ces. & De Not. and L. ogilviensis (Berk. & Broome) Ces. & De Not. (Shoemaker 1984; Farr and Rossman 2018). These species can be distinguished from each other based on ascospore septation. Plenodomus Preuss Plenodomus was introduced by Preuss (1851) and is typified by P. rabenhorstii. Subsequently, Boerema and Kesteren (1964) designated P. lingam (Tode) Höhn. as the type combination over P. rabenhorstii because the type material of P. rabenhorstii was lost during the World War II (de Gruyter et al. 2013; Ariyawansa et al. 2015b; Tennakoon et al. 2017). Based on molecular phylogeny, de Gruyter et al. (2013) reclassified Phoma section Plenodomus and synonymized species in Phoma section Plenodomus under the genus Plenodomus in Leptosphaeriaceae. The genus was re-circumscribed by Ariyawansa et al. (2015b) based on study of type and representative specimens coupled with molecular data. Marin-Felix et al. (2017) and Tennakoon et al. (2017) updated the accounts of Plenodomus based on molecular data. There are 97 epithets available in Index Fungorum (2019). Plenodomus artemisiae A. Karunarathna, Phookamsak & K.D. Hyde, sp. nov.

Notes: Plenodomus artemisiae forms a distinct lineage and is sister to P. salviae Thambug. et al. (MFLUCC 13-0219) with high support (99% ML and 0.99 BYPP; Fig. 12). Plenodomus artemisiae can be distinguished from P. salviae in having shorter and broader, pale brown, fusiform ascospores, enlarged at the third cell from above. Plenodomus salviae has longer and thinner, yellowish brown, cylindric-fusiform ascospores (30–48 9 3.1–4.3 lm), and without the enlarged cell (Ariyawansa et al. 2015b). Plenodomus artemisiae is also similar to Leptosphaeria artemisiae (Fuckel) Auersw. in having 5-septate ascospores, with the enlarged third cell and occurring on Artemisia. However, L. artemisiae has larger ascomata and narrower ascospores (32–37 9 8.5–10; Shoemaker 1984). Furthermore, P. artemisiae has pale brown, fusiform ascospores, whereas, L. artemisiae has light reddish brown, broadly elliptical ascospores (Shoemaker 1984). Phylogenetic affinity of L. artemisiae could not be resolved due to lack of molecular data. 123 Fungal Diversity Fig. 11 Leptosphaeria urticae (MFLU 18-0591, holotype). a–c Appearance of ascomata on host surface. d Section through an ascoma. e Peridium. f Pseudoparaphyses. g–i Asci. j–m Ascospores. n Spore germination on MEA after 24 h. o Culture from above and below.

GenBank numbers: ITS = MK387921, LSU = MK387959, SSU = MK387929, TEF1-a = MK435601 (KUMCC 18-0186). Notes: Based on the NCBI BLASTn search of ITS sequence data, Plenodomus lijiangensis closest match is P. deqinensis Qian Chen & L. Cai (CGMCC 3.18221; 98% similarity). Phylogenetic analyses of a concatenated LSU, SSU and ITS sequence dataset (Fig. 12) reveal that P. lijiangensis forms a sister lineage with P. deqinensis and groups with P. agnitus (Desm.) Gruyter et al., P. fallaciosus (Berl.) Gruyter et al. and P. lupini (Ellis & Everh.) Gruyter et al. Plenodomus lijiangensis shares a size range of conidia and conidiogenous cells with P. deqinensis and was also collected from Yunnan, China (Marin-Felix et al. 2017). However, P. lijiangensis was isolated from dead fronds of fern, while P. deqinensis was isolated from soil. In vitro, P. lijiangensis forms a globose to subglobose conidiomata, inconspicuous ostiole, with a short stipe which is similar to the asexual morph of P. sinensis Tennakoon et al. (Fig. 16). While, P. deqinensis forms globose to subglobose, slightly papillate ostiole with a narrow pore or opening via a rupture (Marin-Felix et al. 2017). A comparison of ITS sequence shows that P. lijiangensis differs from P. deqinensis in eight base positions (1.55%/ 517 bp). According to the guidelines in Jeewon and Hyde (2016), we introduce P. lijiangensis as a new species. Plenodomus sinensis Tennakoon, Phookamsak & K.D.

Notes: Based on the NCBI BLASTn search of ITS sequences, our isolates (KUMCC 18-0152, KUMCC 18-0153 and KUN-HKAS 102227) match with Plenodomus sinensis Tennakoon et al. (MFLU 17-0757), with 99% similarity. The sexual morph of KUMCC 18-0153 and KUN-HKAS 102227 share similar size of ascomata, asci and ascospores with the type, as well as sharing similar ascospore characters with fusiform, 6-septate ascospores (Tennakoon et al. 2017). Phylogenetic analyses of a concatenated LSU, SSU and ITS sequence dataset (Fig. 12) reveal that our isolates cluster with P. sinensis (MFLU170757) with moderate support (86% ML and 0.90 BYPP). The asexual morph of P. sinensis, which is reported for the first time in this study, is similar to the asexual morph of P. lijiangensis in having globose to subglobose conidiomata with a short stipe. However, these two species are phylogenetically distinct. Tennakoon et al. (2017) introduced Plenodomus sinensis as a saprobic species occurring on Plukenetia volubilis and Tamarindus indica from Xishuangbanna, Yunnan, China (tropical rain forest climate). In this study, P. sinensis was found on ferns and Cirsium sp. from Baoshan (mild subtropical highland climate) and Lijiang (a mild, with abundant rainfall and plenty of sunshine climate), Yunnan, China. This indicates that P. sinensis may occur on a wide range of hosts and in different climatic regions. Sphaerellopsis Cooke Sphaerellopsis was introduced by Sutton (1977) to accommodate mycoparasitic taxa occurring on a wide range of rusts and is typified with S. filum (Biv.) B. Sutton. Sphaerellopsis was re-circumscribed by Trakunyingcharoen et al. (2014) and Ariyawansa et al. (2015b) based on molecular phylogeny. The link between the sexual genus Eudarluca Speg. and the asexual genus Sphaerellopsis is still debated. Eudarluca was synonymized under Sphaerellopsis by Rossman et al. (2015) based on holomorphic characters of Eudarluca caricis (Fr.) O.E. Erikss. However, Phookamsak et al. (2014b) re-examined the isotype specimen of Eudarluca australis Speg. and treated Eudarluca in Phaeosphaeriaceae according to the generic type, E. australis is not congeneric with E. caricis. Eudarluca australis is typical of Phaeosphaeriaceae in having uni-loculate ascomata, a thin-walled peridium, comprising 1–2 layers of brown, pseudoparenchymatous cells, cylindrical asci, with pale brown, 123 Fungal Diversity Fig. 13 Plenodomus artemisiae (KUN-HKAS 102226, holotype). a Ascomata on host. b, c Vertical section of ascomata. d Ostiole. e Section through peridium. f Pseudoparaphyses. g–i Asci. j–m Ascospores. n Ascospore germination. o, p Culture characteristics (o = from above, p = from below).

Whereas, E. caricis forms black, multi-loculate ascostroma, with thickwalled peridium (Yuan et al. 1998; confirming the connection of E. caricis and Sphaerellopsis filum).

Asexual morph Undetermined. Material examined: CHINA, Yunnan Province, Baoshan, Shuizai, Dawazi mountain, on dead branches of herbaceous plant, 23 October 2015, R. Phookamsak, BS012 (KUN-HKAS 102225, holotype). GenBank numbers: ITS = MK387925, LSU = MK387963, SSU = MK387933, TEF1-a = MK435604 (HKAS 102225A); ITS = MK387926, LSU = MK387964, SSU = MK387934, TEF1-a = MK435605 (HKAS 102225B). Notes: Sphaerellopsis isthmospora forms a phylogenetically distinct lineage, but clusters with other Sphaerellopsis species in Leptosphaeriaceae (Fig. 12). Sphaerellopsis isthmospora can be distinguished from other Sphaerellopsis species in its sexual morph having isthmosporous ascospores, with 10–12-septate, deeply constricted and bent at the 8th septum. Sphaerellopsis filum (sexual morph: Eudarluca caricis) has spindle-shaped, slightly inequilateral, 2–3-septate ascospores (Yuan et al. 1998). Based on morphological difference and phylogenetic affinity, we therefore, introduce a new species S. isthmospora from herbaceous plant in Baoshan, China. 123 Sphaerellopsis paraphysata Crous & Alfenas, in Trakunyingcharoen et al., IMA Fungus 5(2): 411 (2014) Facesoffungi number: FoF04968, Fig. 18 Holotype: BRAZIL, Minas Gerais, Viçosa, Universidade Federal de Viçosa campus, on rust on Pennisetum sp., 18 November 2012, A.C.

(2014) based on morphological comparisons and phylogenetic analysis. We made a new collection from China associated with a rust on living leaves of Liriope spicata. The new isolate (KUN-HKAS 101483) is similar in morphology with S. paraphysata but differs from the type of S. paraphysata in having smaller conidiomata, presence of conidiophores and lacking paraphyses. Phylogenetic analyses of a combined LSU, SSU and ITS sequence dataset show that our strain (KUMCC 18-0195) forms a sister lineage with S. paraphysata (CPC 21841) with high support (100% ML and 1.00 BYPP). A comparison of ITS nucleotide base shows that our new isolate has same base pairs with the type strain of S. paraphysata. Thus we identify the new isolate as S. paraphysata and our new collection is a new host record in China. Lophiotremataceae K. Hiray. & Kaz. Tanaka Lophiotremataceae was introduced by Hirayama and Tanaka (2011) to accommodate the type genus Lophiotrema Sacc. and is typified by L. nucula (Fr.) Sacc.

Tanaka (Hashimoto et al. 2017; Wijayawardene et al. 2018a). In the present study, a new species, Lophiotrema mucilaginosis collected on dead wood in China, is introduced. a short stipe, hyaline, ellipsoidal to fusiform, septate ascospores and pycnidial coelomycetous asexual morphs (Hirayama and Tanaka 2011; Hirayama et al. 2014; Hashimoto et al. 2017). The genus has a long taxonomic history and has always been confused with Lophiostoma Ces. & De Not. and Massarina Sacc. in previous studies (Zhang et al. 2009b, 2012; Hirayama and Tanaka 2011; Hyde et al. 2013; Hirayama et al. 2014). However, Lophiotrema was re-classified based on molecular data by Hashimoto et al. (2017) and many species of Lophiotrema sensu lato were treated as new genera in Lophiotremataceae. Lophiotrema Sacc. Lophiotrema was introduced by Saccardo (1878) and is typified by L. nucula (Fr.) Ces. & De Not. The genus was established to accommodate taxa in Pleosporales, characterized by ascomata with a slit-like ostioles, a peridium of uniform thickness, cylindrical to cylindric-clavate asci with Lophiotrema mucilaginosis M.

Material examined: CHINA, Yunnan Province, Baoshan City, Longling County, on wood litter, October 2015, M. Raza, BAP 119 (HMAS 255437, holotype), ex-type living culture, LC12112. GenBank numbers: ITS = MH822889, LSU = MH822890, SSU = MH822891, RPB2 = MH822892, TEF1-a = MH822893. Notes: Multi-loci phylogenetic analyses based on a concatenated ITS, LSU, SSU, TEF1-a and RPB2 sequence dataset show that Lophiotrema mucilaginosis forms a wellsupported lineage (100% ML and 1.00 BYPP; Fig. 20), sister to L. hydei J.F. Zhang et al. and clusters with L. neohysterioides M.E. Barr. Lophiotrema mucilaginosis and L. hydei were collected on wood litter and herbaceous plant 123 Fungal Diversity Fig. 19 Lophiotrema mucilaginosis (HMAS 255437, holotype). a Blackish ascomata on dead wood. b Vertical section of ascoma. c Peridial structure. d Pseudoparaphyses. e, f Immature asci. g, h Mature asci. i Apical ring stained with cotton blue. j Immature ascospores. k–o Mature ascospores. p Ascospores with mucilaginous sheath. q Germination of ascospore. r, s Culture characteristics on PDA (r = from above, s = from below).

Lophiotrema mucilaginosis can be distinguished from L. hydei in having larger asci (78–89(– 99) 9 6.9–8.8 lm, L. hydei) and larger ascospores (23–28 9 3–4 lm, L. hydei) (Zhang et al. 2018). In addition, L. mucilaginosis has conical to mammiform ascomata, 123 Fungal Diversity Fig. 20 Phylogenetic tree generated from maximum likelihood analysis (RAxML) based on a combined ITS, LSU, SSU, TEF1-a and RPB2 sequence dataset of genera in Lophiotremataceae. Maximum likelihood bootstrap support values greater than 70% and Bayesian posterior probabilities greater than 0.95 BYPP are indicated on the branches. The new isolate is in blue. The type strains are in bold. The tree is rooted with Cryptocoryneum akitaense (KT 3019) with flattened base and 1(–3)-septate ascospores. Whereas, L. hydei has globose to subglobose ascomata and inconspicuously 0–1-septate ascospores. Lophiotrema mucilaginosis differs from L. neohysterioides by its larger asci (70–96 9 7–10 lm, L. neohysterioides) and larger ascospores (17–25 9 3–5 lm, L. neohysterioides) and presence of mucilaginous sheath surrounding the ascospores, a feature not observed in L. neohysterioides (Tanaka and Harada 2003a). Occultibambusaceae D.Q. Dai & K.D. Hyde Occultibambusaceae was introduced by Dai et al. (2017a) and is typified by Occultibambusa D.Q. Dai & K.D. Hyde with O. bambusae D.Q. Dai & K.D. Hyde being the type species. The family was introduced to accommodate bambusicola-like taxa, mainly occurring on bamboo (Dai et al. 2017a; Doilom et al. 2017). Dai et al. (2017a) accepted four genera in Occultibambusaceae viz. Neooccultibambusa Doilom & K.D. Hyde., Occultibambusa, Seriascoma Phookamsak et al. and Versicolorisporium Sat. Hatak. et al. and this is in agreement of Wijayawardene et al. (2018a). Subsequent authors introduced new taxa in this family (Hyde et al. 2016, 2018b; Zhang et al. 2017b; Tibpromma et al. 2018). We follow the latest treatment of Occultibambusaceae in Dai et al. (2017a) and introduce the new genus, Brunneofusispora S.K. Huang & K.D. Hyde to accommodate Brunneofusispora sinensis and other isolates of Massarina rubi. The updated sequence data were retrieved from Zhang et al. (2017b). 123 Brunneofusispora S.K. Huang & K.D. Hyde, gen. nov. Index Fungorum number: IF555599; Facesoffungi number: FoF04862 Etymology: The generic epithet ‘‘Brunneofusispora’’ refers to the taxon having brown, fusiform ascospores. Saprobic on dead wood. Sexual morph Ascomata solitary to scattered, immersed, eventually erumpent, globose to subglobose, uni-loculate, glabrous, dark brown to black, ostiolate, with long beak. Peridium composed of brown to hyaline pseudoparenchymatous cells of textura angularis. Hamathecium composed of numerous, filamentous, septate pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, cylindrical to clavate, short pedicellate, rounded at the apex, with an ocular chamber. Ascospores overlapping 2-seriate, hyaline to brown, broadly fusiform, 1-septate, constricted at the septum, smooth-walled, with guttules, surrounded by a mucilaginous sheath. Asexual morph Undetermined. Type species: Brunneofusispora sinensis S.K. Huang & K.D. Hyde Notes: Multigene phylogenetic analyses reveal that our new taxon forms a distinct lineage, but clusters with three isolates of Massarina rubi (Fuckel) Sacc. (current name: Lophiotrema rubi (Fuckel) Y. Zhang ter et al.) in Occultibambusaceae (Fig. 21). We introduce a new genus Brunneofusispora to accommodate B. sinensis, which was collected from a woody plant in Yunnan, China. Brunneofusispora resembles Neooccultibambusa in occurring on woody plants and forming globose to subglobose ascomata, Fungal Diversity Fig. 21 Maximum likelihood phylogenetic tree generated from analysis of a combined LSU, SSU, ITS, RPB2 and TEF1-a sequence dataset for 77 taxa of representative families in Pleosporales. Melanomma pulvispyrius (CBS 124080) was selected as the outgroup taxon. ML and MP support values greater than 60% and Bayesian posterior probabilities greater than 0.90 BYPP are indicated above the nodes as ML/PP/MP. The strain numbers are noted before the species names. Isolates from this study are indicated in blue. Ex-type strains are indicated in bold but Brunneofusispora differs from Neooccultibambusa in having a long prominent neck (Doilom et al. 2017). Brunneofusispora resembles Lophiotrema in having cylindrical, cylindric-clavate asci and fusiform ascospores, but it differs from Lophiotrema in having globose to subglobose ascomata, with a long prominent neck. Lophiotrema species have minute papilla, with crest-like or slitlike openings (Zhang et al. 2009b; Hashimoto et al. 2017). Lophiotrema rubi (: Masarina rubi) is an orphan species in Lophiotremataceae, which was transferred from Massarina based on phylogenetic analysis by Zhang et al. (2009b). It is characterized by immersed ascomata with broadly fusiform ascospores (Saccardo 1883b; Aptroot 1998). In this study, L. rubi strains CBS 691.95, MUT 4323 and MUT 4887 clustered with our strain (KUMCC 17-0030) and they form an independent clade within Occultibambusaceae (Fig. 21).

We therefore, tentatively include these strains of Massarina rubi until they are clarified base on evidence from morphology and phylogeny. Etymology: The specific epithet ‘‘sinensis’’ refers to the country, China, where the taxon was collected. Holotype: KUN-HKAS 97451. Saprobic on dead wood.

We follow the latest treatment and updated accounts of Parabambusicolaceae in Tanaka et al. (2015), Li et al. (2016), Phukhamsakda et al. (2016, 2018) and Wanasinghe et al. (2017). Two novel genera are introduced based on molecular phylogeny (Fig. 23) coupled with morphological characterization viz. Lonicericola and Paratrimmatostroma. In addition, a novel species Parabambusicola thysanolaenae is introduced. Lonicericola Phookamsak, Jayasiri & K.D. Hyde, gen. nov. Index Fungorum number: IF556139; Facesoffungi number: FoF04962 Etymology: The generic epithet ‘‘Lonicericola’’ refers to the host genus Lonicera, from which the type species was collected. Saprobic o dead hanging branches of Lonicera maackii. Sexual morph Ascomata black, scattered, solitary to gregarious, immersed under host epidermis, slightly raised, globose to subglobose, uni-loculate, glabrous, ostiolate, papillate. Peridium of equal thickness, composed of several layers, of flattened to broad, brown to dark brown, pseudoparenchymatous cells, arranged in textura angularis to textura prismatica. Hamathecium composed of numerous, filamentous, septate, anastomosed pseudoparaphyses, embedded in a hyaline gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, broadly cylindrical to cylindricclavate, subsessile to short pedicellate, with furcate to obtuse pedicel, apically rounded, with ocular chamber. Ascospores overlapping 2–3-seriate, hyaline, fusiform to vermiform, with enlarged cell, septate, constricted at the septa, smooth-walled, surrounded by distinct mucilaginous sheath. Asexual morph Undetermined. Type species: Lonicericola hyaloseptispora Phookamsak, Jayasiri & K.D. Hyde Notes: Lonicericola is similar to the sexual genera Aquastroma Kaz. Tanaka & K. Hiray., Multiseptospora Phookamsak & K.D. Hyde, Neoaquastroma Wanas. et al. and Parabambusicola Kaz. Tanaka & K. Hiray in Parabambusicolaceae, in having hyaline, fusiform to vermiform, multi-septate ascospores, with an entire sheath (Liu et al. 2015a; Tanaka et al. 2015). Lonicericola can be distinguished from these related genera based on habitat, ascomal shape, ascospore septation and multigene phylogenetic evidence. Lonicericola can be distinguished from Aquastroma based on its terrestrial habitat, broadly cylindrical to cylindric-clavate asci, with a subsessile to short pedicel and 9-septate ascospores. Aquastroma was found on submerged woody plant from aquatic habitat and has clavate asci, with a longer pedicel and 6–8-septate ascospores (Tanaka et al. 2015). Lonicericola resembles Multiseptospora in having globose to subglobose ascomata immersed in the host tissue. However, Multiseptospora has 10–11-septate ascospores, the ascomata are covered by brown to dark brown vegetative hyphal tufts, lack papilla, and have pore-like openings (Liu et al. 2015a). Neoaquastroma has 3–7-septate ascospores in N. guttulatum, 4–7-septate in N. bauhiniae and 5–8-septate in N. krabiense (Wanasinghe et al. 2017; Phukhamsakda et al. 2018). The asexual morph of Neoaquastroma has been reported as coelomycetous; whereas an asexual morph is not yet known for Lonicericola. Parabambusicola differs from Lonicericola in having hemispherical to conical ascomata, with a flattened base, and 5–6-septate ascospores as well as occurring on bamboo and stout grasses (Tanaka et al. 2015). Multigene phylogenetic analyses reveal that Lonicericola forms a distinct lineage with Aquastroma, Multiseptospora, Neoaquastroma and Parabambusicola and clusters with the hyphomycetous genera Pseudomonodictys Doilom et al. and Paratrimmatostroma Jayasiri et al. with moderate support (77% ML and 0.99 BYPP). A comparison of ITS, LSU, SSU and TEF1-a sequence data indicates that Lonicericola differs from Pseudomonodictys in 97/593 bp (16.4%, ITS), 14/888 bp (1.6%, LSU), 18/1033 bp (1.7%, SSU) and 36/959 bp (3.7%, TEF1-a). However, we could not compare the morphological characteristics of Lonicericola with Pseudomonodictys and Paratrimmatostroma as they are represented by different morphs. 123 Fungal Diversity Fig. 23 Simplified phylogram showing the best RAxML tree obtained from a combined multigene (SSU, ITS, LSU and TEF1-a) analyses.

Ascospores of P. thysanolaenae are 5-septate and shorter than the 3–5-septate ascospores of P. bambusina (54.7 9 8.4 lm, Tanaka and Harada 2003b). Phylogenetically P. thysanolaenae clusters with P. bambusina forming a well-separated lineage (100% ML and 1.00 BYPP; Fig. 23). Paratrimmatostroma Jayasiri, Phookamsak, D.J. Bhat & K.D. Hyde, gen. nov. Index Fungorum number: IF556153; Facesoffungi number: FoF04960 Etymology: With reference to similar morphology of genus ‘‘Trimmatostroma’’ Saprobic on dead fronds of a fern. Sexual morph Undetermined. Asexual morph Hyphomycetous. Sporodochia effuse or confluent, visible as black powdery, superficial mass on host substrate, flattened, light brown, with a membranous base, composed of pseudoparenchymatous cells of textura angularis. Mycelium immersed, composed of septate, pale brown, branched hyphae. Conidiophores macronematous, or semi-macronematous, mononematous, prostrate, or erect, usually short, oblong to cylindrical, straight or flexuous, arising as lateral branches from creeping hyphae, septate, branched or unbranched, slightly constricted at the septa so as to give a monilioid appearance, pale brown, smooth-walled. Conidiogenous cells holoblastic, mono- to polyblastic, integrated, terminal, brown, smooth-walled. Conidia solitary, acropleurogenous, dark brown, paler at the apical cell, branched, straight or flexuous, variable in shape, helicoid, cylindrical, sigmoid, or reniform, solitary, tapering near apex and base, rounded at tip, septate, constricted at the septa, smooth and thickwalled. Type species: Paratrimmatostroma kunmingensis Jayasiri, Phookamsak, D.J. Bhat & K.D.

Scale bars a = 200 lm, b = 50 lm, d–q = 10 lm Notes: Paratrimmatostroma is similar to Trimmatostroma Corda in forming effuse to confluent sporodochia, semi-macronematous, mononematous conidiophores, integrated, terminal conidiogenous cells, and branched, straight or flexuous, septate, pigmented conidia, which are variable in shape (Ellis 1971; Crous et al. 2007a). However, they are phylogenetically distinct in that Paratrimmatostroma belongs to Parabambusicolaceae (Pleosporales, Dothideomycetes), whereas Trimmatostroma was recently treated in Mollisiaceae Rehm (Helotiales, Leotiomycetes) (Crous et al. 2007a; Wijayawardene et al. 2018a). Multigene phylogenetic analyses show that Paratrimmatostroma forms a well-resolved clade (74% ML and 1.00 BYPP; Fig. 23), and clusters with Pseudomonodictys and Lonicericola. Paratrimmatostroma is distinct from Pseudomonodictys in forming sporodochia on the host substrate and having branched, straight or flexuous conidia, with variable conidial shape. Pseudomonodictys has muriform, top-shaped to ellipsoidal conidia and does not form sporodochia on host 123 substrate (Ariyawansa et al. 2015a). Paratrimmatostroma was found on a fern in Yunnan, China (nonflowering vascular plants in the low-latitude monsoon climate), whereas, Pseudomonodictys was collected from teak in Thailand (flowering plant in tropical climate). A comparison of ITS, LSU, SSU and TEF1-a sequence dataset indicates that Paratrimmatostroma differs from Pseudomonodictys in 64/540 bp (11.8%, ITS), 23/857 bp (2.7%, LSU), 22/1060 bp (2.1%, SSU) and 41/928 bp (4.4%, TEF1-a). Based on phylogenetic analysis and morphological distinctiveness, we introduce Paratrimmatostroma as a new genus to accommodate a single species, P. kunmingensis.

Periconiaceae has long been unused and placed as members of Massarinaceae Munk until Tanaka et al. (2015) revised Massarineae and placed it as a distinct family based on phylogenetic analysis (Tanaka et al. 2015; Hyde et al. 2017, 2018b). We follow the latest treatment and updated accounts of Periconiaceae in Tanaka et al. (2015), Hyde et al. (2017, 2018b), Liu et al. (2017b) and Thambugala et al. (2017). We report Periconia cortaderiae Thambug. & K.D. Hyde from Caragana arborescens Lam. (Fabaceae) in Yunnan, China for the first time. Periconia Tode Periconia was introduced by Tode (1791) to accommodate hyphomycetous species having macronematous conidiophores and 1-celled, pigmented, verruculose to echinulate conidia and is typified by P. lichenoides Tode (Tanaka et al. 2015; Thambugala et al. 2017). The genus was re-circumscribed by Tanaka et al. (2015) and this was followed by subsequent authors (Hyde et al. 2017, 2018b; Liu et al. 2017b; Thambugala et al. 2017). We follow the latest treatment of Periconia in Tanaka et al. (2015). The updated phylogenetic analyses were retrieved from Thambugala et al. (2017) and Hyde et al. (2018b) (Fig. 27).

Taxa in Morosphaeriaceae, Morosphaeria ramunculicola (KH 220) and M. velatispora (KH 221) were selected as the outgroup taxa. Bootstrap support values for maximum likelihood (green) equal to or greater than 70% and the Bayesian posterior probabilities (blue) equal or higher than 0.95 are indicated above the nodes.

Notes: Phylogenetic analyses of a concatenated LSU, ITS and TEF1-a sequence datset show that our strains (MFLUCC 18-0667 and MFLUCC 18-0668) form a wellresolved clade, clustering with Periconia cortaderiae (100% ML and 1.00 BYPP; Fig. 27). A comparison of ITS and TEF1-a nucleotide base pair indicates that our strains are identical to the type strain of P. cortaderiae, which is not significantly different (2/520 bp in ITS and 4/830 bp in TEF1-a). We therefore, identify our isolates as P. cortaderiae and report its occurrence on Caragana arborescens in Yunnan, China for the first time. Our isolate has shorter conidiophores (400–800 lm high, holotype) and slightly larger conidia (4–6.6 9 4.1–7.1 lm, holotype) (Thambugala et al. 2017).

Phaeosphaeriaceae M.E. Barr Phaeosphaeriaceae was introduced by Barr (1979) to accommodate fungal taxa which mainly occurr on monocotyledons, but are also found on some herbaceous plants (Phookamsak et al. 2014b, 2017). Many additional genera have been introduced in this family since Phookamsak et al. (2014b) re-circumscribed the genera in Phaeosphaeriaceae. Wijayawardene et al. (2018a) listed 52 genera in Phaeosphaeriaceae. Wanasinghe et al. (2018), Bakhshi et al. (2019) and Maharachchikumbura et al. (2019) introduced other seven genera in this family, and 59 genera are now accepted in Phaeosphaeriaceae based on molecular phylogeny coupled with morphological characteristics (Wanasinghe et al. 2018; Wijayawardene et al. 2018a). We follow the latest treatment and updated accounts of Phaeosphaeriaceae in Phookamsak et al. Fig. 29 Phylogram generated from maximum likelihood analysis c based on a concatenated LSU, SSU, TEF1-a and ITS sequence dataset of Phaeosphaeriaceae.

(2018b) and Wanasinghe et al. (2018). A new genus Brunneomurispora is introduced to accommodate a single species, B. lonicerae. Five new species are also introduced viz. Galiicola baoshanensis, Neosetophoma lonicerae, Ophiobolus malleolus, Phaeosphaeria cycadis and Wojnowiciella kunmingensis. Furthermore, Wojnowicia rosicola W.J Li et al. is transferred to Wojnowiciella. Amarenomyces dactylidis Mapook et al. is reported from a fern in China for the first time. An updated phylogenetic analysis (Fig. 29) was performed following 123 previous phylogenies derived from Hyde et al. (2018b) and Wanasinghe et al. (2018). Amarenomyces O.E. Erikss. Amarenomyces was introduced by Eriksson (1981) and is typified by A. ammophilae (Lasch) O.E. Erikss., occurring on marine grass (Ammophila arenaria L., Poaceae). The genus is characterized by immersed to erumpent, globose to subglobose ascomata, thin-walled peridium, multi-layered endotunica, broadly cylindrical asci, with subsessile, knob-like pedicel and large, pigmented, septate, thick-walled and sheathed ascospores (Phookamsak et al. Fungal Diversity 2014b). Eriksson (1981) placed the genus in Botryosphaeriaceae Theiss. & Syd.; however, Zhang et al. (2009a) treated the genus as a synonym of Phaeosphaeria I. Miyake in Phaeosphaeriaceae based on molecular phylogeny. Phookamsak et al. (2014b) re-circumscribed the genera in Phaeosphaeriaceae based on multigene phylogenetic analyses coupled with morphological studies and thus, Amarenomyces was re-instated. Hyde et al. (2017) introduced a second species, A. dactylidis Mapook et al., collected from dead aerial stems of Dactylis glomerata L. in Italy. Only two species are presently accommodated in this genus.

Sexual morph Ascomata 170–230 lm high, 160–260 lm diam., scattered, solitary, semi-immersed to superficial, visible as raised, black dots on the host surface, globose to subglobose, uniloculate, glabrous, ostiole central, with minute, papilla (20– 45 9 25–55 lm, l/w), lacking periphyses. Peridium 13– 23 lm wide, thin-walled of equal thickness, composed of 5–6 cell layers, of flattened to broad, pseudoparenchymatous cells; outer layer comprising brown to dark brown cells of textura angularis; inner layer comprising flattened, hyaline to pale brown cells, of textura angularis to textura prismatica. Hamathecium composed of numerous, 1.8– 4.5 lm wide, filamentous, septate, pseudoparaphyses, anastomosing above the asci, embedded in a hyaline gelatinous matrix. Asci (70–)75–95(–113) 9 (9.5–)10– 13(–14) lm ( x = 88.9 9 12 lm, n = 30), 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-clavate, short pedicellate, with furcate pedicel, apically rounded, with well-developed ocular chamber. Ascospores (19–)(23–)25– 28(–32) 9 4.5–6 lm ( x = 26.1 9 5.5 lm, n = 50), overlapping 1–2-seriate, yellowish brown to brown, fusiform to subcylindrical, slightly narrower towards the end cells, asymmetrical, 7–8-septate, slightly constricted at the septa, enlarged at the 5th or 6th cell from above, flattened at the 2nd to 4th, or 5th cells, smooth-walled, surrounded by a distinct mucilaginous sheath. Asexual morph Undetermined. Culture characteristics: Colonies on PDA reaching 35–38 mm diam. after 3 weeks at room temperature (20–30 °C). Colony dense, irregular in shape, flattened to slightly raised, surface smooth, with edge undulate, velvety to floccose; from above, initially white, with pale grey at the centre, becoming greenish grey after 4 weeks; from below, white to pale yellowish at the margin, dark brown at the centre, becoming black after 4 weeks; not producing pigmentation on agar medium. Material examined: CHINA, Yunnan Province, Baoshan, Shuizai, Dawazi mountain, on dead fronds of a fern, 22 October 2015, I.D. Goonasekara, BS008 (KUNHKAS 102230), living culture, KUMCC 18-0154. Known hosts and distribution: On dead aerial stems of Dactylis glomerata (Poaceae, Italy) and on dead fronds of a fern (Yunnan, China) (Hyde et al. 2017; this study). GenBank numbers: ITS = MK356371, LSU = MK356345, SSU = MK356359. Notes: Multigene phylogenetic analyses show that the new strain KUMCC 18-0154 is sister to Amarenomyces dactylidis (MFLUCC 14-0207) with high support (98% ML and 1.00 BYPP). A comparison of ITS nucleotide base pairs shows that KUMCC 18-0154 is identical (1/541 bp) to A. dactylidis and thus, we identify our new isolate as A. dactylidis. Our isolate (KUN-HKAS 102230) shares a size range of the ascomata, asci and ascospores as well as the ascospore septation with the type (MFLU 17-0498). Although, our isolate is slightly larger in ascomata, asci and ascospores, but ITS sequence data showed that they are conspecific (Hyde et al. 2017). Therefore, A. dactylidis is reported from a fern in Yunnan, China for the first time. Brunneomurispora Phookamsak, Wanas. & K.D. Hyde, gen. nov. Index Fungorum number: IF556165; Facesoffungi number: FoF05699 Etymology: The generic epithet ‘‘Brunneomurispora’’ refers to the fungus having brown, muriform ascospores. Saprobic on Lonicera maackii. Sexual morph Ascomata scattered, solitary or in groups, semi-immersed to erumpent, globose to subglobose, or irregular in shape, uniloculate, glabrous, ostiolate, papillate. Peridium slightly thick, composed of several layers, of small, flattened to broad, dark brown, pseudoparenchymatous cells of textura angularis to textura prismatica. Hamathecium composed of numerous, broad, filamentous, septate, anastomosed pseudoparaphyses, embedded in a hyaline gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, broadly cylindrical to cylindric-clavate, or clavate, short pedicellate, apically rounded, with inconspicuous ocular chamber. Ascospores overlapping 1–2-seriate, dark brown, muriform, fusiform to ellipsoidal, asymmetrical, slightly larger in the upper part, constricted at the central septum, smoothwalled, lacking mucilaginous sheath. Asexual morph Undetermined. Type species: Brunneomurispora lonicerae Phookamsak, Konta, Wanas. & K.D. Hyde Notes: Phylogenetic analyses of a concatenated LSU, SSU, TEF1-a and ITS sequence dataset (Fig. 29) show that our new strains (KUMCC 18-0157 and KUMCC 18-0158) 123 Fungal Diversity form a well-separated lineage basal to Neosetophoma Gruyter et al. with high support (94% ML and 0.99 BYPP). Our new isolate is distinct from Neosetophoma in having dark brown muriform ascospores. While, the sexual morph of Neosetophoma has phragmosporous, brown, fusiform ascospores (Tibpromma et al. 2017; Hyde et al. 2018b). Hence, we introduce a new genus Brunneomurispora herein to accommodate B. lonicerae which was isolated from Lonicera maackii in Yunnan, China. Brunneomurispora resembles Embarria Wanas. et al. and Hydeomyces Maharachch. et al. in having immersed to erumpent, globose or subglobose ascomata, with a minute papilla, clavate asci, with dark brown, muriform, asymmetrical ascospores and ascospores that are constricted at the central septum (Wanasinghe et al. 2018; Maharachchikumbura et al. 2019). However, Brunneomurispora can be distinguished from Embarria in its peridium structure comprising several layers of brown, small, flattened to broad pseudoparenchymatous cells and its ascospores being 4–6 transverse septa, with 1–2 longitudinal septa, sectored, and lacking a mucilaginous sheath. Embarria has a thin-walled peridium, comprising large, 2–3 cell layers of pseudoparenchymatous cells and its ascospores are 4–6 transverse septa, with a single longitudinal septum, surrounded by a thick mucilaginous sheath (Wanasinghe et al. 2018). Hydeomyces differs from Brunneomurispora in having thicker peridium (35–60 lm thick), smaller, cylindrical asci (70–85 9 9–17 lm) and smaller, 1-seriate, muriform ascospores, with 2–4 transverse septa and 1 longitudinal septum (10–15 9 5–6.5 lm) (Maharachchikumbura et al. 2019). Hawksworthiana lonicerae Wanas. et al. was also isolated from Lonicera in Italy. This species differs from Brunneomurispora lonicerae in having cylindrical to cylindric-clavate asci, with yellowish brown, ellipsoidal, muriform, 3 transverse septa, with 1 longitudinal septum ascospores (Wanasinghe et al. 2018). Many genera in Phaeosphaeriaceae are characterized by dictyosporous ascospores viz. Allophaeosphaeria Ariyaw. et al., Dactylidina Wanas. et al., Dematiopleospora Wanas. et al., Embarria, Galiicola Tibpromma et al., Hawksworthiana Wanas. et al., Hydeomyces Maharachch. et al., Italica Wanas. et al., Muriphaeosphaeria Phukhams. et al., Populocrescentia Wanas. et al. and Yunnanensis Karun. et al. (Wanasinghe et al. 2014b, 2018; Ariyawansa et al. 2015a; Liu et al. 2015a; Phukhamsakda et al. 2015; Karunarathna et al. 2017; Maharachchikumbura et al. 2019). These genera are represented by a single or a few species and have very little morphological differences in their sexual morphs. However, they always form distinct clades, separate from each other, as well as the asexual morphs of some different genera. Furthermore, Poaceicola and Populocrescentia are heterogeneous, forming both 123 phragmosporous and dictyosporous ascospores (Wanasinghe et al. 2018). More sampling of taxa in these genera are needed for a better understanding. Brunneomurispora lonicerae Phookamsak, Konta, Wanas. & K.D. Hyde, sp. nov.

GenBank numbers: ITS = MK356374, LSU = MK356348, SSU = MK356362, TEF1-a = MK359066. Notes: Multigene phylogenetic analyses of a combined LSU, SSU, TEF1-a and ITS sequence dataset show that Galiicola baoshanensis forms a sister lineage with the generic type of Galiicola, G. pseudophaeosphaeria with high support (100% ML and 1.00 BYPP; Fig. 29). A comparison of TEF1-a sequences indicates that G. baoshanensis differs from G. pseudophaeosphaeria in 14/730 bp (1.9%). However, we could not compare the morphological characters of G. baoshanensis with G. pseudophaeosphaeria as they are represented by different morphs. Galiicola baoshanensis is introduced as the asexual species in Galiicola for the first time. Galiicola baoshanensis is similar to Amarenographium ammophilae Wanas. et al. in having conidia that are muriform, clavate, ellipsoidal, ovoid or fusoid conidia, with rounded apex, acute or truncate base, and 7–9 transverse septa (Wijayawardene et al. 2016). However, G. 123 baoshanensis can be distinguished from A. ammophilae in having brown to dark brown conidia, with 2–4 longitudinal septa and lacking appendages at the apex and the base. Whereas, A. ammophilae has yellowish brown to brown conidia, with 1–3 longitudinal septa and appendages at the apex and the base (Wijayawardene et al. 2016). A comparison of ITS and TEF1-a sequences indicates that G. baoshanensis differs from A. ammophilae in 71/570 bp (12.5%) and 58/899 bp (6.5%), respectively. Muti-gene phylogenetic analyses also supported their distinctiveness (Fig. 29). Neosetophoma Gruyter et al. We follow the latest treatment and updated accounts of Neosetophoma in Hyde et al. (2018b) and Wanasinghe et al. (2018). Seventeen species are known in this genus (Hyde et al. 2018b; Index Fungorum 2019). Neosetophoma lonicerae Phookamsak, Wanas. & K.D. Hyde, sp. nov. Index Fungorum number: IF556168; Facesoffungi number: FoF05702, Fig. 33 Etymology: The specific epithet ‘‘lonicerae’’ refers to the host genus Lonicera, from which the holotype was collected. Holotype: KUN-HKAS 102231 Saprobic on Lonicera maackii. Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata 110–160 lm high, 80–160 lm diam., pycnidial, scattered, solitary to gregarious, immersed to semi-immersed, uniloculate, globose to subglobose, glabrous, dark brown to black, visible as small black dot on the host surface, associating with other fungal taxa, ostiole central, occasionally near the centre, minutely mammiform papilla. Conidiomata walls 5–12 lm wide, equally thin-walled, composed of 2–3 cell layers, of broad, brown to dark brown pseudoparenchymatous cells, arranged in a textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 3.5–7 9 (3–)5–10 lm ( x = 6.2 9 6.7 lm, n = 20), enteroblastic, phialidic, discrete, determinate, ampulliform to doliiform, unbranched, aseptate, hyaline, smooth, minute collarette with periclinal wall thickening, arising from the inner cavity of the conidioma wall. Conidia (8.5–)9–12(–14) 9 4–5 lm ( x = 11 9 4.8 lm, n = 50), yellowish brown, ellipsoidal, 1–3-septate, not constricted at the septa, smooth-walled, lacking mucilaginous sheath surrounding conidia. Culture characteristics: Colonies on PDA reaching 33–35 mm diam. after 3 weeks at room temperature (20–30 °C). Colony medium dense, circular, flattened to raised, surface slightly rough with hyphal tufts, edge entire, velvety to fluffy; from above, white to white yellowish at the margin, light green to yellowish green at the centre; from below, radiating outwards colony, white to cream at Fungal Diversity Fig. 31 Brunneomurispora lonicerae (KUN-HKAS 102232, holotype). a Appearance of ascomata on host. b Close up of ascoma on host. c Section through ascoma. d Section through peridium. e Cellular pseudoparaphyses. f–i Asci. j–o Ascospores.

Material examined: CHINA, Yunnan Province, Kunming City, Kunming Institute of Botany, on dead hanging branches of Lonicera maackii, 20 April 2017, R. Phookamsak, KIB033 (KUN-HKAS 102231, holotype), ex-type living culture, KUMCC 18-0155 (KIB033A), KUMCC 18-0156 (KIB033B). GenBank numbers: ITS = MK356375, LSU = MK356349, SSU = MK356363, TEF1-a = MK359067 (KUMCC 18-0155); ITS = MK356376, LSU = MK356350, SSU = MK356364, TEF1-a = MK359068 (KUMCC 18-0156). Notes: In the NCBI BLASTn search of ITS sequence, Neosetophoma lonicerae has a closest match with fungal endophyte species (M16-3161) with 100% similarity and is closely related to N. italica W.J. Li et al., N. rosarum R.H. Perera et al., N. samarorum (Desm.) Gruyter et al. and N. rosigena Wanas. et al. with 98% similarity. Multigene phylogenetic analyses based on a combined LSU, SSU, TEF1-a and ITS sequence dataset show that N. lonicerae forms a separate lineage, clustering with N. rosigena, N. samarorum and N. garethjonesii Tibpromma et al. with moderate support (76% ML and 0.98 BYPP; Fig. 29). A comparison of ITS nucleotide base pairs shows that N. lonicerae differs from N. rosigena, N. samarorum and N. garethjonesii in 14/555 bp (2.5%), 15/555 bp (2.7%) and 123 Fungal Diversity Fig. 32 Galiicola baoshanensis (KUN-HKAS 102234, holotype). a Appearance of conidiomata on host. b Section through conidioma. c Ostiole with pore-like opening. d Section through conidioma wall. e–g Conidiogenous cells. h Conidium when immature. i–m Conidia. Scale bars a = 200 lm, b = 50 lm, d = 20 lm, c, g–m = 10 lm, e, f = 5 lm 16/522 bp (3%), respectively. We therefore, introduce N. lonicerae as a new species following the guidelines of Jeewon and Hyde (2016). Neosetophoma lonicerae is similar to some other Neosetophoma species in having pale brown to brown, oblong to ellipsoidal, or subfusoid, 1–3-septate conidia; such as in N. iranianum Papizadeh et al., N. italica, N. rosae R.H. Perera et al., N. rosarum and N. shoemakeri Senwanna et al. However, they can be distinguished based on their conidial size, host occurrence and phylogenetic distance (Liu et al. 2015a; Karunarathna et al. 2017; Hyde et al. 2018b; Wanasinghe et al. 2018). Ophiobolus Riess We follow the latest treatment and updated accounts of Ophiobolus in Phookamsak et al. (2017). 123 Ophiobolus malleolus S.K. Huang, Bulgakov & K.D. Hyde, sp. nov. Index Fungorum number: IF554782; Facesoffungi number: FoF04686, Fig. 34 Etymology: The specific name ‘‘malleolus’’ refers to the hammer-shaped at top of the ascospores. Holotype: MFLU 15-2230. Saprobic on dead stems of Cirsium arvense (Asteraceae). Sexual morph Ascomata 230–270 lm high, 265– 310 lm diam., scattered, solitary to gregarious, immersed, eventually erumpent, uni-loculate, globose to subglobose, Fungal Diversity Fig. 33 Neosetophoma lonicerae (KUN-HKAS 102231, holotype). a Appearance of conidiomata on host. b Section through conidioma. c, d Section through conidioma wall. e–h Conidiogenous cells. i–n Conidia. o Germinated conidium. p, q Culture characteristics on PDA (p = from above, q = from below). Scale bars a = 200 lm, b = 50 lm, c–h, o = 10 lm, i–n = 5 lm dark brown to black, papillate. Ostiole central, short papilla, filled with periphyses. Peridium 25–60 lm wide, thick-walled, composed of several cell layers of brown to dark brown cells, paler to hyaline towards the inner layers, outer layer comprising black, coriaceous stratum, arranged in a textura angularis. Hamathecium composed of numerous, 1–3 lm wide, filamentous, septate pseudoparaphyses, anastomosing at the apex, embedded in a gelatinous matrix. Asci 125–155 9 12–15 lm ( x = 140 9 12.5 lm, n = 20), 8-spored, bitunicate, cylindric-clavate, subsessile to short pedicellate, with knob-like or truncate pedicel, rounded at the apex, with a distinct ocular chamber. Ascospores 100–112 9 2.5–4.5 lm ( x = 107.5 9 3.5 lm, n = 50), fasciculate, in parallel or spiral, initially hyaline, becoming brown at maturity, guttulate, filiform, enlarged at the first cell with hammer-like, tapering towards the end cell, up to 15 septa, curved, slightly constricted at the septa at maturity, smooth-walled, with apical mucilaginous cap. Asexual morph Undetermined. Culture characteristics: Ascospores germinating on PDA, colony reaching 10 mm diam. after 2 weeks at room temperature (20–30 °C). Colony dense, irregular in shape, flattened to umbonate, surface smooth, with edge erose, velvety to floccose; from above, cream; from below, cream to pale yellowish; not producing pigmentation on agar medium. Material examined: RUSSIA, Rostov region, Krasnosulinsky District, Donskoye forestry, arboretum (47.8547249̊N, 40.2318907̊E), on dead stems of Cirsium arvense (Asteraceae), 28 June 2015, T.S. Bulgakov, T-526 (MFLU 15-2230, holotype), ex-type living culture, MFLUCC 15-1077. GenBank numbers: ITS = MH399730, LSU = MH399731, SSU = MH399729. Notes: Multigene phylogenetic analyses reveal a close phylogenetic affinity between Ophiobolus malleolus and O. disseminans (Fig. 29, 68% ML and 1.00 BYPP). Ophiobolus malleolus is distinct from O. disseminans in its ascospores being filiform with an enlarged at the apical cell similar to a hammer-like, with apical mucilaginous cap, 123 Fungal Diversity and not splitting into two part spores. Ophiobolus disseminans has filiform ascospores with two swollen cells near the centre, lacks an apical mucilaginous cap, and splits into two part spores at the central septum (Phookamsak et al. 2014b, 2017). Ophiobolus anguillides (Cooke) Sacc. also has filiform ascospores enlarged hammer-like at the apical cell and an apical mucilaginous cap. However, O. anguillides has larger ascomata and ascospores (500–600 lm diam., and 120–130 9 2.5–3 lm; Shoemaker 1976). Ophiobolus anguillides has been reported from many hosts, mainly on Artemesia in Europe and North America (Shoemaker 1976; Farr and Rossman 2018). However, the species has never been reported from Cirsium arvense. Unfortunately, there is no molecular data available for O. anguillides. Phaeosphaeria I. Miyake We follow the latest treatment and updated accounts of Phaeosphaeria in Phookamsak et al. (2014b), Hyde et al. (2017) and Tibpromma et al. (2017). More than 200 epithets are listed under Phaeosphaeria in Index Fungorum (2019); however, the phylogenetic affinities of few species have been confirmed based on molecular data. Some species listed under Phaeosphaeria have already been transferred to other related genera in Phaeosphaeriaceae and other related families (Phookamsak et al. 2014b; Ariyawansa et al. 2015a; Tennakoon et al. 2016). Phaeosphaeria cycadis Wanas., Phookamsak & K.D. Hyde, sp. nov. Index Fungorum number: IF556169; Facesoffungi number: FoF05703, Fig. 35 Etymology: The specific name ‘‘cycadis’’ refers to the host family Cycadaceae, of which the holotype was collected. Holotype: KUN-HKAS 102235 Associated with leaf spots on Cycas sp. (Cycadaceae). Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata (60–)100–160 lm high, (60–) 135–200 lm diam., pycnidial, visible as black dot on host surface, scattered to clustered, solitary to gregarious, semiimmersed to erumpent, uni-loculate, subglobose to ampulliform, or irregular in shape, ostiolate, with minute papilla. Conidiomata walls 10–20(–30) lm wide, composed of 4–5 cell layers, of brown to dark brown pseudoparenchymatous cells, of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells (3.5–)4.5–8 9 4–8 (–10) lm ( x = 6.4 9 5.7 lm, n = 30), ampulliform to broadly conical, gradually tapering toward the apex, holoblastic, phialidic, hyaline, smooth-walled, with periclinal wall thickening, arising from the inner cavity of the conidioma wall. Conidia (10–)12–14(– 16) 9 3–5 lm ( x = 12.9 9 3.9 lm, n = 50), pale brown to light yellowish, oblong to ellipsoidal, or subcylindrical, (0–)1–2-septate, 123 truncate to obtuse base, with obtuse apex, not constricted at the septa, smooth-walled. Culture characteristics: Colonies on PDA reaching 50–52 mm diam. after 3 weeks at room temperature (20–30 °C). Colony dense, irregular in shape, flattened, surface slightly smooth, edge undulate, with entire margin, cottony to floccose, slightly sparse near the margin; from above, white to cream, slightly radiated outwards colony; from below, slightly radiating, cream at the margin, pale brown to yellowish-brown at the centre, sectering with golden brown; not producing pigmentation on agar medium. Material examined: CHINA, Yunnan Province, Kunming City, Kunming Institute of Botany, associated with leaf spots on Cycas sp. (Cycadaceae), 5 April 2017, R. Phookamsak, KIB022 (KUN-HKAS 102235, holotype), ex-type living culture, KUMCC 18-0161 (KIB022A), KUMCC 18-0162 (KIB022B). GenBank numbers: ITS = MK356378, LSU = MK356352, SSU = MK356366, TEF1-a = MK359069 (KUMCC 18-0161); ITS = MK356379, LSU = MK356353, SSU = MK356367, TEF1-a = MK359070 (KUMCC 18-0162). Notes: In the NCBI BLASTn search of ITS sequences, Phaeosphaeria cycadis most closely matches P. acaciae Tennakoon et al. with 99% similarity. Multigene phylogenetic analyses based on a combined LSU, SSU, TEF1-a and ITS sequence dataset show that P. cycadis forms a sister lineage with P. acaciae with high support (100% ML and 1.00 BYPP; Fig. 29). The ITS gene could not clarify the novelty of P. cycadis in this study as the species is not significantly different from P. acaciae in a comparison of ITS sequences (5/452 bp). Phookamsak et al. (2014b) mentioned that Phaeosphaeria contains species complexes that cannot be resolved based only on the ITS gene and that a combination of protein coding genes, such as TEF1-a and RPB2, is necessary to clarify species in this genus. Based on morphological characteristics, P. cycadis differs from P. acaciae in having larger conidia (P. cycadis, (10–)12–14 (– 16) 9 3–5 lm versus 8–12 9 2.4–3.5 lm, P. acaciae; Hyde et al. 2017), with (0–)1–2 conidial septa and is associated with leaf spots on Cycas sp. Phaeosphaeria acaciae has 1–3 conidial septa and occurs on dead stems of Acacia sp. as a saprobe (Hyde et al. 2017). Furthermore, P. acaciae produced a pink pigment on PDA, but this is absent in P. cycadis. We therefore, introduce P. cycadis as a new species in this study based on its morphological distinctiveness. Wojnowiciella Crous et al. Wojnowiciella was introduced by Crous et al. (2015b) and is typified by W. eucalypti Crous et al. Crous et al. (2015a) treated Wojnowicia as a synonym of Septoriella Fungal Diversity 123 Fungal Diversity b Fig. 34 Ophiobolus malleolus (MFLU 15-2230, holotype) a Herbar- ium label. b Appearance of ascomata on Cirsium arvense stems. c Ascomata on host. d Ascoma in vertical section. e Peridium. f Pseudoparaphyses. g–i Developing stages of the asci. j–m Ascospores (note: m stained in Indian ink). Scale bars c = 500 lm, d = 100 lm, e = 50 lm, f–m = 20 lm Oudem. based on nomenclature study and this is in agreement of Wijayawardene et al. (2017a). Subsequently, all identified Wojnowicia species in Phaeosphaeriaceae were synonymized under Wojnowiciella (Crous et al. 2015b; Hernandez-Restrepo et al. 2016). Wojnowiciella can be distinguished from Wojnowicia Sacc. in having apapillate, glabrous conidiomata and dark brown conidia (Crous et al. 2015b). Wojnowicia was introduced by Saccardo (1892) and is characterized by setose conidiomata (Crous et al. 2015a; Wijayawardene et al. 2016). Seven species are accommodated in this genus (Index Fungorum 2019). Wojnowiciella kunmingensis Phookamsak, Wanas. & K.D. Hyde, sp. nov. Index Fungorum number: IF556170; Facesoffungi number: FoF05704, Fig. 36 Etymology: The specific epithet ‘‘kunmingensis’’ refers to Kunming Institute of Botany, Kunming City, Yunnan Province, China, where the holotype was collected. Holotype: KUN-HKAS 102233 Saprobic on Lonicera maackii. Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata 110–190 lm high, 110–190 lm diam., pycnidial, scattered, solitary to gregarious, immersed, slightly raised, visible as small black dot on host surface, uni-loculate, globose to subglobose, glabrous, dark brown to black, ostioles central, apapillate, with pore-like opening. Conidiomata walls 5– 12 lm wide, thin-walled, of equal thickness, composed of 1–3 cell layers, of flattened, dark brown, pseudoparenchymatous cells, arranged in a textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells (3–)4–6.5(–9) 9 (2.5–)3.5–6(–8) lm l/w ( x = 5 9 5.3 lm, n = 40), holoblastic, phialidic, discrete, determinate, ampulliform to doliiform, unbranched, aseptate, hyaline, smooth, arising from the inner cavity of the conidioma wall. Conidia (16–)18–24(–27.5) 9 4–6(–7) lm l/w ( x = 22 9 5.6 lm, n = 50), dark brown, subcylindrical to fusiform, or reniform, slightly curved, with acute to rounded apex, and rounded to truncate base, 3–7septate, not constricted at the septa, thick-walled, smoothwalled, with guttules, having flattened, mucous caps at both ends. Culture characteristics: Colonies on PDA reaching 35–38 mm diam. after 2 weeks at room temperature (20–30 °C). Colony medium dense, slightly irregular in 123 shape, flattened to slightly raised, surface slightly rough with greyish-green hyphal tufts, edge undulate, with entire margin, floccose; from above, slightly radiating, white to cream at the margin, pale brown at the middle, separated from the margin with brown to dark green concentric ring near the edge, greyish green to dark green at the centre; from below, white to cream margin, brown to dark brown at the centre; not producing pigmentation on agar medium. Material examined: CHINA, Yunnan Province, Kunming City, Kunming Institute of Botany, on dead hanging branches of Lonicera maackii, 20 April 2017, R. Phookamsak, KIB031 (KUN-HKAS 102233, holotype), ex-type living culture, KUMCC 18-0159 (KIB031A), KUMCC 18-0160 (KIB031B). GenBank numbers: ITS = MK356380, LSU = MK356354, SSU = MK356368, TEF1-a = MK359071 (KUMCC 18-0159); ITS = MK356381, LSU = MK356355, SSU = MK356369, TEF1-a = MK359072, RPB2 = MK359078 (KUMCC 18-0160). Notes: In the NCBI BLASTn search of ITS sequences, Wojnowiciella kunmingensis most closely matches W. dactylidis (Wijayaw. et al.) Hern.-Restr. & Crous, W. spartii (W.J. Li et al.) Hern.-Restr. & Crous and Wojnowicia italica Qing Tian et al. with 99% similarity. ITS and TEF1-a genes could not resolve the novelty of the Wojnowiciella species in this study. A comparison of ITS and TEF1-a nucleotide bases shows that Wojnowiciella kunmingensis is not significantly different from W. dactylidis and other Wojnowiciella species as well as Wojnowicia italica. However, a comparison of RPB2 sequence data shows that Wojnowiciella kunmingensis differs from W. dactylidis and Wojnowicia italica in 21/856 bp (2.4%) and 20/954 bp (2.1%), respectively. Multigene phylogenetic analyses based on a combined LSU, SSU, TEF1-a and ITS sequence data show that Wojnowiciella kunmingensis forms a sister lineage with W. dactylidis and clusters with other Wojnowiciella species (Fig. 29). However, W. kunmingensis differs from W. dactylidis in having 3–7-septate conidia, while W. dactylidis has 7–11-septate conidia (Liu et al. 2015a). Wojnowiciella leptocarpi Crous et al. also has 3–7-septate conidia, with mucous caps at both ends. However, W. kunmingensis has longer conidia ((16–)18–24(– 27.5) 9 4–6(–7) lm versus 26–36 9 4–6 lm; HernandezRestrepo et al. 2016), that are brown to dark brown, and smooth-walled. The conidia of W. leptocarpi are orange brown, thick-walled, and verruculose (Hernandez-Restrepo et al. 2016). A comparison of RPB2 sequence data shows that W. kunmingensis differs from W. leptocarpi in 29/851 bp (3.4%). Wojnowiciella lonicerae (Wijayaw. et al.) Hern.-Restr. & Crous was also collected from Lonicera, but it has 8–11-septate conidia (Liu et al. 2015a).

Notes: Wojnowiciella rosicola was introduced by Wanasinghe et al. (2018) as Wojnowicia rosicola W.J. Li et al. The species clustered with other Wojnowiciella species in Phaeosphaeriaceae that were previously treated in Wojnowicia and recently treated as a synonym of Wojnowiciella by Crous et al. (2015a, b) and HernandezRestrepo et al. (2016). Based on morphological characteristics and phylogenetic analyses, the species is congeneric with Wojnowiciella. We therefore, treat W. rosicola as a new combination. Pseudoastrosphaeriellaceae Phookamsak & K.D. Hyde Pseudoastrosphaeriellaceae was introduced by Phookamsak et al. (2015b) to accommodate a monotypic genus 123 Fungal Diversity Fig. 36 Wojnowiciella kunmingensis (KUN-HKAS 102233, holotype). a Appearance of conidiomata on host. b Section through conidioma. c Section through conidioma wall. d–g Conidiogenous cells. h–k Conidia. l Germinated conidium.

This family is characterized by hemispherical to lenticular ascostromata, globose to subglobose ascomata with a flattened or rounded base, immersed beneath host epidermis, erumpent through host surface by a papilla, with short to long necks, trabeculate pseudoparaphyses, short pedicellate, cylindric-clavate to clavate asci, and hyaline or brown, septate ascospores and coelomycetous asexual morphs (Phookamsak et al. 2015b). Based on close morphological characteristics and phylogenetic support, Hyde et al. (2017) accommodated Carinispora K.D. Hyde in Pseudoastrosphaeriellaceae and this was followed by Wijayawardene et al. (2018a). In this study, we introduce a 123 Fungal Diversity new genus Pseudoastrosphaeriellopsis typified by P. kaveriana in Pseudoastrosphaeriellaceae based on molecular phylogeny coupled with morphological characteristics. Pseudoastrosphaeriellopsis Devadatha, Wanas., Jeewon & V.V. Sarma, gen. nov. Index Fungorum number: IF555790; Facesoffungi number: FoF05706 Etymology: Generic epithet in resemblance to Pseudoastrosphaeriella Saprobic on decaying stems and twigs of Avicennia marina and Suaeda monoica, black spots, with short necks on host surface. Sexual morph Ascomata light brown, solitary to gregarious, immersed to erumpent, globose to subglobose with a rounded base, uni-loculate, coriaceous, brown, short papillate, ostiolate. Ostioles central, cylindrical, straight to oblique, with ostiolar canal lined by hyaline periphyses. Peridium thin- to thick-walled, unequally thickened, composed of two layers, inner stratum with hyaline to pale brown compressed cells of textura angularis, outer stratum with compact brown polygonal cells of textura angularis, fused with the host tissue. Hamathecium composed of numerous, filamentous, septate, branched, hyaline pseudoparaphyses. Asci 8-spored, bitunicate, cylindric-clavate to clavate, with a short, thick pedicel, apically rounded and thickened with an ocular chamber. Ascospores overlapping 1–2-seriate, brown, fusiform to broadly fusiform, slightly curved with round to acute ends, slightly constricted at the 3rd septum and rarely at other septa, broader in the middle and tapering towards the ends, septate, with hyaline apical and terminal ends, smooth-walled, lacking guttules and mucilaginous sheath. Asexual morph Undetermined. Type species: Pseudoastrosphaeriellopsis kaveriana Devadatha, Wanas., Jeewon & V.V. Sarma Notes: The genus Pseudoastrosphaeriella Phookamsak et al. was introduced by Phookamsak et al. (2015b) to accommodate P. aequatoriensis (K.D. Hyde & J. Fröhl.) Phookamsak & K.D. Hyde, P. africana (D. Hawksw.) Phookamsak & K.D. Hyde, P. bambusae Phookamsak & K.D. Hyde, P. longicolla Phookamsak & K.D. Hyde, P. papillata (K.D. Hyde & J. Fröhl.) Phookamsak & K.D. Hyde and P. thailandensis Phookamsak et al. based on morphology and multigene phylogenetic analyses. Some of the species were previously treated in Astrosphaeriella Syd. & P. Syd. Maximum likelihood tree (Fig. 37) generated based on a combined LSU, SSU, ITS, RPB2 and TEF1-a dataset reveals that our new taxon clusters within Pseudoastrosphaeriellaceae sister to Pseudoastrosphaeriella with 63% ML and 0.95 BYPP statistical support. Tree topologies generated under ML and Bayesian criteria from combined datasets were congruent, whereas maximum parsimonious tree was varied, which showed that our taxon forms a clade between Testudinaceae Arx and Tetraplosphaeriaceae Kaz. Tanaka & K. Hiray. without any statistical support. Further comparison of LSU nucleotides between our taxon and Pseudoastrosphaeriella thailandensis (GenBank: KT955478) resulted in 62/871 (7.1%) base pair differences which confirms its placement as a new genus in Pseudoastrosphaeriellaceae. Pseudoastrosphaeriellopsis shares morphological similarity with Pseudoastrosphaeriella in having immersed ascomata underneath the host epidermis, erumpent, uniloculate, coriaceous, brown, and short papillate asci, with trabeculate pseudoparaphyses (Phookamsak et al. 2015b). However, Pseudoastrosphaeriellopsis can be distinguished from Pseudoastrosphaeriella in having globose to subglobose ascomata, immersed in host tissue, with fusiform to broadly fusiform ascospores. Pseudoastrosphaeriellopsis kaveriana resembles Neotrematosphaeria biappendiculata (Kaz. Tanaka et al.) Thambug. et al., but differs in having immersed ascomata, with pore-like ostiole, and ascospores lacking appendages, whereas, the latter has semi-immersed ascomata, with crest-like ostiole, and ascospores with appendages at both ends (Thambugala et al. 2015). Biappendiculispora japonica Thambug. et al. differs from Pseudoastrosphaeriellopsis kaveriana in having slit-like ostioles, bulbous pedicels and 7–9 transverse septa ascospores with appendages (Thambugala et al. 2015). Pseudoastrosphaeriellopsis kaveriana also shares similarities with Trematosphaeria wegeliniana L. Holm & K. Holm, T. hydrophila Sacc. and T. crassisepta Kaz. Tanaka et al. in having 5-septate ascospores and overlapping ascospore dimensions, but is clearly distinct in having immersed ascomata beneath the host epidermis, short papilla and light brown, fusiform to broadly fusiform, slightly curved ascospores (Tanaka et al. 2015). Trematosphaeria wegeliniana and T. hydrophila lack a detailed description from type material and their taxonomic position remains unclear (Tanaka et al. 2015). Thambugala et al. (2015) transferred Trematosphaeria terricola G.S. Gong to Alpestrisphaeria terricola (G.S. Gong) Thambug. & K.D. Hyde and Trematosphaeria biappendiculata (KTC 1124) to the new genus Neotrematosphaeria biappendiculata based on their morphological resemblance to Lophiostomataceae and multigene phylogeny. Our combined multiloci phylogenetic analysis also reveals that taxonomic position of some species in Trematosphaeria remains unclear and this needs further collection and revision.

We follow the latest treatment and updated accounts of Roussoellaceae in Liu et al. (2014), Dai et al. (2017a), Tibpromma et al. (2017), Hyde et al. (2018b), Jayasiri et al. (2019) and Jiang et al. (2019). Phylogenetic affinities of the family were discussed by Jaklitsch and Voglmayr (2016) where Roussoellaceae was treated as a synonym of Thyridariaceae. However, Tibpromma et al. (2017) reinstated Roussoellaceae based on multigene phylogenetic analysis which showed Roussoellaceae is a well-resolved family in Pleosporales and this was concurred by Wanasinghe et al. (2018), Wijayawardene et al. (2018a), Jayasiri et al. (2019) and Jiang et al. (2019). Seven genera were accepted in this family based on molecular data and morphological characteristics (Wijayawardene et al. 2018a). Taxonomic status of genera in Roussoellaceae is doubtful and needs to be clarified due to taxa in these genera have similar conidial characters and phylogeny has always shown that they are monophyletic (Liu et al. 2014; Dai et al. 2017a; Tibpromma et al. 2017; Hyde et al. 2018b; Jiang et al. 2019). However, Neoroussoella Phookamsak et al. and Roussoellopsis I. Hino & Katum. are distinct from Roussoella but these two genera usually cluster with Roussoella species (Liu et al. 2014; Phookamsak et al. 2014a; Dai et al. 2017a; Tibpromma et al. 2017; Hyde et al. 2018b; Jiang et al. 2019). Wanasinghe et al. (2018) introduced Pseudoneoconiothyrium (Phukhams. et al.) Phukhams. et al. and Pararoussoella to accommodate roussoella-like taxa in Thyridariaceae. We use increased taxon sampling in our phylogenetic analysis (Fig. 39) and show that the two genera erected by Wanasinghe et al. (2018), cluster with Roussoella species in Roussoellaceae. Jayasiri et al. (2019) clarified Neoroussoella based on multigene phylogenetic analysis coupled with morphological characteristics, N. entadae Jayasiri et al. and N. leucaenae Jayasiri et al. were introduced. Roussoella solani Crous & M.J. Wingf. was transferred to Neoroussoella as N. solani (Crous & M.J. Wingf.) Jayasiri & K.D. Hyde. In addition, Roussoella mukdahanensis Phookamsak et al. was transferred to Pararoussoella as P. mukdahanensis (Phookamsak et al.) Jayasiri & K.D. Hyde. In this study, Neoroussoella heveae Senwanna et al. and Roussoella elaeicola Konta & K.D. Hyde are introduced as novel 123 Fungal Diversity species based on morphological characteristics coupled with multigene phylogenetic analysis. In addition, Neoroussoella leucaenae is described on Hevea brasiliensis Müll.Arg. from Thailand for the first time. Neoroussoella J.K. Liu et al. We follow the latest treatment and updated accounts of Neoroussoella in Jayasiri et al. (2019). Neoroussoella heveae Senwanna, Phookamsak & K.D. Hyde, sp. nov.

Notes: Neoroussoella heveae is introduced based on morphological and phylogenetic evidence. Our strain forms a separate lineage, clusters with Neoroussoella species (78% ML; Fig. 39). Neoroussoella heveae differs from the asexual morph of Neoroussoella species in having verruculose conidia, whereas, other Neoroussoella species have smooth-walled conidia. 123 Neoroussoella leucaenae Jayasiri, E.B.G.

Material examined: THAILAND, Chiang Rai Province, on dead petiole of Elaeis guineensis (Arecaceae), 25 November 2014, S. Konta, HR02d (MFLU 15-0022, holotype), ex-type living culture, MFLUCC 15-0276. GenBank numbers: ITS = MH742329, LSU = MH742326 (MFLUCC 15-0276a); ITS = MH742330, LSU = MH742327 (MFLUCC 15-0276b); LSU = MH742328, SSU = MH742331 (MFLUCC 15-0276c). Notes: Roussoella elaeicola (MFLU 15-0022) is introduced as a novel species and it was collected from oil palm (Elaeis guineensis) in Chiang Rai, Thailand for the first time. Multigene phylogenetic analyses show that R. elaeicola has a close relationship with R. euonymi Crous & Akulov and Pseudoneoconiothyrium rosae Phukhams et al. (Fig. 39) which were collected from Euonymus europaeus L. (Celastraceae) in Ukraine and on dead aerial spines of Rosa canina L. (Rosaceae) in Italy, respectively (Crous et al. 2018; Wanasinghe et al. 2018). However, we could not compare the morphological characteristics of our new species with these two species as Roussoella euonymi and 123 Pseudoneoconiothyrium rosae are only known as asexual morph species, while our new taxon is represented by the sexual morph. One of the distinctive characters of Roussoella elaeicola is the distinctive trabeculate pseudoparaphyses (sensu Liew et al. 2000). A comparison of ITS nucleotide base pairs indicates that Roussoella elaeicola differs from R. euonymi and Pseudoneoconiothyrium rosae in 37/513 bp (7.2%) and 38/514 bp (7.4%). Roussoella elaeicola can be distinguished from other Roussoella species by its ascospores having poroid ornamentation, similar to R. scabrispora (Liu et al. 2014). However, R. elaeicola and R. scabrispora form a distinct lineage in Roussoellaceae. Sulcatisporaceae Kaz. Tanaka & K. Hiray. Sulcatisporaceae was introduced by Tanaka et al. (2015) to accommodate three genera: Magnicamarosporium Kaz. Tanaka & K. Hiray., Neobambusicola Crous & M.J. Wingf. and Sulcatispora Kaz. Tanaka & K. Hiray. and is typified by Sulcatispora. The family is characterized by globose to subglobose, ostiolate, papillate ascomata, a thick-walled peridium with a poorly developed base, and trabeculate, anastomosed pseudoparaphyses, bitunicate, clavate asci, and hyaline, broadly fusiform, 1-septate ascospores with an entire sheath. The asexual morphs are coelomycetous, with ellipsoid to subglobose, hyaline to dark brown, muriform or phragmosporous conidia (Crous et al. 2014b; Tanaka et al. 2015; Phukhamsakda et al. 2017). Five species from three genera are accommodated in this family. We introduce a new species, Neobambusicola brunnea (MFLU 18-1393) based on a phylogenetic analysis of a combined LSU and ITS sequence dataset (Fig. 43). Neobambusicola Crous & M.J. Wingf. Neobambusicola was introduced as a monotypic genus by Crous et al. (2014b) and is typified by N. strelitziae Crous & M.J. Wingf., isolated from leaves of Strelitzia nicolai in South Africa. The genus was represented by its asexual morph and is characterized by erumpent, globose, dark brown, ostiolate conidiomata, a thin-walled of peridium, subcylindrical to ampulliform, phialidic conidiogenous cells and hyaline to olivaceous, fusoid-ellipsoid, smooth-walled, 1-septate conidia with hyaline, smooth, guttulate to granular, aseptate, subglobose to subcylindrical microconidia (Crous et al. 2014b). Crous et al. (2014b) treated the genus in Bambusicolaceae. Tanaka et al. (2015) introduced a new family Sulcatisporaceae to accommodate Neobambusicola, Magnicamarosporium and Sulcatispora. Only Neobambusicola strelitziae was accommodated in Neobambusicola, but we introduce a second species N. brunnea which is represented by the sexual morph. Neobambusicola brunnea Y. Chen & Norphanphoun, sp. nov. Fungal Diversity Index Fungorum number: IF555293; Facesoffungi number: FoF05708, Fig. 44 Etymology: The specific epithet ‘‘brunnea’’ refers to the brownish ascospores. Holotype: MFLU 18-1393 Saprobic on dead stem of herbage. Sexual morph Ascomata 80–205 lm high, 90–260 lm diam., semi-immersed, blackish, irregular in shape, scattered on surface of stem, uni-loculate, glabrous, ostiolate, apapillate. Ostioles 35.5–68 lm diam., dark, circular and sunken at the apex of ascoma. Peridium 30–40 lm thick, two layered, thickwalled, outer layer irregular, comprising dark brown cells of textura angularis and inner layer slightly, irregular of light brown cells. Hamathecium comprising 1–2 lm wide, filamentous, branched or simple, septate, anastomosed, cellular pseudoparaphyses, embedded in a hyaline gelatinous matrix. Asci 70–90 9 8–10 lm ( x = 83.6 9 9 lm, n = 10), 4- or 8-spored, bitunicate, cylindrical to cylindricclavate, short pedicellate, apically rounded, with an ocular chamber. Ascospores 11–18 9 5–6 lm ( x = 12.9 9 5.8 lm, n = 20), 1-seriate, brown to dark brown, oblong to ellipsoidal, with rounded ends, 1-septate, slightly constricted at the septum, smooth-walled, with small guttules. Asexual morph Undetermined. Material examined: CHINA, Guizhou Province, Qiandongnan Miao and Dong Autonomous Prefecture, Huangping District, on dead stem of herbage, 10 September 2017, Y. Chen, QDN001 (MFLU 18-1393, holotype). GenBank numbers: ITS = MH644792, LSU = MH644791. Notes: DNA was extracted directly from the ascomata, and a phylogenetic analysis of combined ITS and LSU sequence dataset shows that Neobambusicola brunnea is closely related to N. strelitziae with moderate support (87% ML; Fig. 43). A comparison of ITS and LSU pair wise shows that N. brunnea differs from N. strelitziae in 31 and 40 base positions, respectively. Therefore, N. brunnea is introduced as a novel species and this is the first report of the sexual morph of Neobambusicola. Thyridariaceae Q. Tian & K.D. Hyde Thyridariaceae was introduced by Hyde et al. (2013) to accommodate the genus Thyridaria Sacc. and is typified by T. broussonetiae (Sacc.) Traverso. The familial concept was solitary or gregarious, immersed to erumpent, globose, coriaceous ascomata, in valsoid configurations, with stromatic, pigmented, prosenchymatous tissues and ostioles with a disc-like ostiolar canal. Asci are fissitunicate, cylindrical to subclavate, pedicellate, with trabeculate pseudoparaphyses and ascospores are pigmented, ellipsoidal to fusiform and verruculose, with transverse eusepta or distosepta, and form coelomycetous Cyclothyrium asexual morphs (Hyde et al. 2013; Jaklitsch and Voglmayr 2016). Jaklitsch and Voglmayr (2016) excluded Cyclothyrium from Thyridariaceae and the genus was tentative placed in Pleosporales, genera incertae sedis (Wijayawardene et al. 2018a). Furthermore, they also synonymized Roussoellaceae under Thyridariaceae and accepted Neoroussoella, Thyridaria, Roussoella, Roussoellopsis and Parathyridaria Jaklitsch & Voglmayr. However, Tibpromma et al. (2017) reinstated Roussoellaceae and this was followed by subsequent authors (Hyde et al. 2018b; Wanasinghe et al. 2018; Wijayawardene et al. 2018a; Jayasiri et al. 2019; Jiang et al. 2019). Recently, Wanasinghe et al. (2018) introduced three new genera in Thyridariaceae viz. Cycasicola Wanas et al., Pseudoneoconiothyrium and Pararoussoella Wanas et al. However, in the present study Pseudoneoconiothyrium and Pararoussoella cluster with other Roussoella species in Roussoellaceae. Devadatha et al. (2018) also introduced a new genus Thyridariella Devadatha et al. in Thyridariaceae. Thyridariella clustered with Cycasicola in our study (Fig. 39). However, these two genera are represented by different morphs and we therefore, treat them as different genera until a link between these two genera is proven. In this study, we introduce a novel genus Liua to accommodate a novel species Liua muriformis in Thyridariaceae based on morphological distinctiveness and phylogenetic support. Liua Phookamsak & K.D. Hyde, gen. nov. Index Fungorum number: IF556175; Facesoffungi number: FoF05709 Etymology: In honour of Jian-Kui Liu, for his excellent work on taxonomic revision of Dothideomycetes. Saprobic on Lonicera maackii. Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata pycnidial, scattered, solitary, immersed, slightly raised, visible as small black dot on host surface, uni-loculate, globose to subglobose, glabrous, dark brown to black, ostioles central, apapillate, with pore-like opening. Conidiomata walls thin-walled, of equal thickness, composed of 3–5 cell layers, of flattened, brown to dark brown, pseudoparenchymatous cells, arranged in a textura angularis to textura prismatica. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, phialidic, discrete, determinate, ampulliform to cylindrical, unbranched, aseptate, occasionally 1–2-septate, hyaline, smooth, arising from the inner cavity of the conidioma wall. Conidia phragmosporous to muriform, dark brown, oblong to ellipsoidal, or obovoid, (2–)3-transversely septate, with (0–)3 longitudinal septa, slightly constricted at the septa, smooth-walled.

(MFLU 17-0581) with 93% similarity. Multigene phylogenetic analyses based on a combined LSU, SSU, ITS, TEF1-a and RPB2 sequence dataset show that L. muriformis forms a sister clade with C. goaensis and C. leucaenae Jayasiri et al. with high support (100% ML and 1.00 BYPP) and clusters with other two Thyridariella species in Thyridariaceae. Liua muriformis 123 differs from C. goaensis and C. leucaenae in having dark brown, muriform or phragmosporous conidia, whereas, C. goaensis and C. leucaenae have pale yellowish, aseptate conidia (Wanasinghe et al. 2018; Jayasiri et al. 2019).

Dothideomycetes, orders incertae sedis Asterinales M.E. Barr ex D. Hawksw. & O.E. Erikss. Asterinaceae Hansf. Asterinaceae was introduced by Hansford (1946) to accommodate obligate biotrophic, or epiphytic fungi which formed web-like, black colonies on the upper and lower surfaces of leaves, or stems, with or without appressoria of external mycelium, superficial, dimidiate ascomata with radiating star-like openings, fissitunicate asci, cylindrical, 2–6-celled, yellowish to brown ascospores and forming both coelomycetous and hyphomycetous asexual morphs (Hyde et al. 2013; Hongsanan et al. 2014, 2016; Guatimosim et al. 2015). Twenty-one genera are accepted in the family (Wijayawardene et al. 2018a). Updated molecular phylogeny and their evolutionary relationships based on molecular clock evidence were provided by Hongsanan et al. (2016) and Liu et al. (2017a). Lembosia Lév. The genus Lembosia was described by Léveillé (1845), based on the type species, L. tenella Lév. The genus is characterized by having lirelliform or V–Y-shaped ascomata, opening by a longitudinal fissure, absence of hypostroma, adhering to the host by superficial hyphae with lateral appressoria (hyphopodia), bitunicate asci disposed as an upright palisade layer, and 2-celled brownish ascospores (Hongsanan et al. 2014). More than 260 epithets are listed under Lembosia in Index Fungorum (2019). However, few species have molecular data. In this manuscript we introduce the new species Lembosia brigadeirensis (Fig. 46). Lembosia brigadeirensis Firmino, A.R. Machado & O.L. Pereira, sp. nov. MycoBank number: MB822355; Facesoffungi number: FoF04108, Fig. 47 Etymology: Name derived from the mountain range where the fungus was collected, Serra do Brigadeiro. Holotype: VIC 44208 Epiphyllous on Epidendrum sp. Sexual morph Colonies 4–6 mm diam., amphigenous, circular to irregular, single to confluent, dark brown, black. Hyphae 4–5 lm diam., straight to flexuous, irregularly branched, brown, septate, hyphal cells cylindrical, smooth. Appressoria 5.5–7.5 9 6–8 lm, few, entire to lobate, sessile, lateral, alternate to unilateral, never opposed, globose, unicellular, straight, brown, penetration peg central on the appressorial cell. Ascomata 530–1180 9 140–230 lm, superficial, hysterothecia, lirelliform, V–Y-shaped, mostly linear, on the top of mycelial mat, single to confluent, fringed at margins, massed in the centre of the colony, opening by longitudinal fissures, dark brown to black, wall of textura radiate to irregulata, cells isodiametric to cylindrical. Pseudoparaphyses up to 2.5 lm wide, cylindrical, filiform, septate, unbranched, hyaline. Asci 30–47.5 9 15–22 lm, 8-spored, bitunicate, fissitunicate, subclavate to cylindrical, disposed as an upright palisade layer. Ascospores 17.5–19.5 9 5.5–8 lm, cylindrical to oblong-clavate, ends rounded, straight or slightly arched, 1-septate, constricted at the median septum, hyaline, becoming brown at maturity, smooth-walled. Asexual morph Undetermined. Material examined: BRAZIL, Minas Gerais, Araponga, Parque Estadual da Serra do Brigadeiro, on leaves of Epidendrum sp. (Orchidaceae), 10 September 2014, A.L. Firmino (VIC 44208, holotype). GenBank numbers: ITS = MF667946, LSU = MF664531. Notes: Lembosia brigadeirensis is a distinct species when compared with many other Lembosia species reported on Orchidaceae (Léveillé 1845; Horne 1905; Sydow 1939; Silva and Pereira 2008; Hosagoudar et al. 2009; Firmino and Pereira 2014).

Scale bars a = 200 lm, b = 50 lm, c = 20 lm, l, m = 10 lm, d–k = 5 lm most similar to L. sertiferae Syd., which has epiphyllous colonies, lobate appressoria, ellipsoid to oblong asci, and fusiform to oblong ascospores (Firmino and Pereira 2014). Lembosia bezerrae Firmino & O.L. Pereira has epiphyllous colonies, smaller appressoria, saccate to ovoid asci, and fusiform and smaller ascospores than L. brigadeirensis (Firmino and Pereira 2014). Lembosia epidendri Meir. Silva & O.L. Pereira has narrow hyphae, wider appressoria, smaller hysterothecia, saccate to ovoid asci, branched pseudoparaphyses, and larger and fusiform ascospores (Silva and Pereira 2008; Firmino and Pereira 2014). Lembosia dendrochili Lév. differs from L. brigadeirensis in having smaller hysterothecia, and larger asci (Léveillé 1845; Firmino and Pereira 2014). Lembosia rolfsii W.T. Horne differs from L. brigadeirensis in the subcuticular mycelium and conidia on superficial mycelium, and probably belonging to Maheshwaramyces (Hosagoudar et al. 2009; Firmino and Pereira 2014). Based on LSU sequence data, Lembosia brigadeirensis is 97% similarity to Prillieuxina baccharidincola (Rehm) Petr. (GenBank no. KP143735), 95% similarity to Asterina melastomatis Lév. (GenBank no. KP143739) and 94% similarity to Alysidiella suttonii Cheew. & Crous (GenBank no. HM628777). Based on ITS sequence data, L. brigadeirensis is 88% similarity to Blastacervulus eucalypti H.J. Swart (GenBank no. GQ303271), Alysidiella suttonii (GenBank no. HM628774), and Heteroconium kleinzeense Crous & Z.A. Pretorius (GenBank no. EF110616). Phylogenetic analysis of LSU sequence dataset (Fig. 46) shows that Lembosia brigadeirensis forms a sister lineage with Prillieuxina baccharidincola (VIC42817) with high support (100% BYPP). Lembosia differs from Prillieuxina G. Arnaud and Asterina Lév. in having elliptical to cylindrical ascomata with longitudinal fissure. Alysidiella Crous and Blastacervulus H.J. Swart are asexual morph genera belonging to the same family as Lembosia (Asterinaceae), but with no known connection to a 123 Fungal Diversity sexual morph. Heteroconium Petr. is also an asexual morph, but belonging to Herpotrichiellaceae (Chaetothyriales). Phylogenetic analyses based on a combined ITS, LSU, TEF1-a and TUB2 sequence dataset are provided for the genera Dothiorella (Fig. 48) and Sphaeropsis (Fig. 51). Botryosphaeriales Schoch et al. Dothiorella Sacc. We follow the latest treatment and updated accounts of Dothiorella in Yang et al. (2017). Updated phylogenetic analysis was retrieved from Dissanayake et al. (2017) and Wanasinghe et al. (2018). Botryosphaeriaceae Theiss. & P. Syd. Botryosphaeriaceae can be found as endophytes, saprobes and plant pathogens on various substrates worldwide (Liu et al. 2012b; Slippers et al. 2013; Dissanayake et al. 2016; Phillips et al. 2018; Jayawardena et al. 2019). The family comprises 28 genera and more than 190 species (Phillips et al. 2018; Tibpromma et al. 2018; Wijayawardene et al. 2018a). We follow the latest treatments and updated accounts in Dissanayake et al. (2016), Hyde et al. (2016), Yang et al. (2017), Phillips et al. (2018), Wanasinghe et al. (2018) and Jayawardena et al.

Conidiomata walls 15–40 lm wide, composed of several layers of broad to flattened, dark brown to black, pseudoparenchymatous cells of textura angularis to textura prismatica, with flattened, hyaline cells towards the inner layers. Conidiophores reduced to conidiogenous cells. Conidiogenous cells (7–)9–15(–24) 9 3–6(–7) lm l/w ( x = 13.2 9 4.5 lm, n = 30), holoblastic, phialidic, discrete, determinate, ampulliform to cylindrical, unbranched, aseptate, hyaline, smooth, arising from the inner cavity of the conidioma wall.

Culture characteristics: Colonies on PDA reaching 70–73 mm diam. after 1 week at 20–30 °C; initially medium sparse to dense, circular, or slightly irregular in shape, surface smooth, with edge entire to lobate; from above, initially white, becoming white-grey to grey; from below, grey to pale yellowish; not producing pigmentation on agar medium. Material examined: CHINA, Yunnan Province, Kunming, Panlong, Ciba, on dead hanging twigs of Acer palmatum Thunb. (Sapindaceae), 28 November 2015, R. Phookamsak, COE009 (KUN-HKAS 102213, holotype), ex-type living culture KUMCC 18-0137. GenBank numbers: ITS = MK359449, TEF1a = MK361182. Notes: In the NCBI BLASTn search of ITS and TEF1-a sequences, Dothiorella acericola is most similar to D. viticola A.J.L. Phillips & J. Luque, with 99% and 98% similarities, respectively. Phylogenetic analyses of a combined ITS and TEF1-a sequence dataset show that D. acericola is sister to Spencermartinsia alpina Y. Zhang ter & Ming Zhang and distinct from D. viticola (Fig. 48). Dothiorella acericola, Spencermartinsia alpina and S. yunnana Zhang ter & Ming Zhang were collected from Yunnan, China, but they are phylogenetically distant (Zhang et al. 2016). Dothiorella acericola has the same size range of conidia as Spencermartinsia alpina and S. yunnana (Zhang et al. 2016). A comparison of TEF1-a nucleotide bases shows that D. acericola differs from Spencermartinsia alpina and S. yunnana in 11/225 bp (4.9%) and 13/225 bp (5.8%), respectively. Therefore, we introduce a new species, D. acericola in this study based on the guidelines of Jeewon and Hyde (2016). Yang et al. (2017) treated Spencermartinsia as a synonym of 123 Fungal Diversity Dothiorella. Spencermartinsia alpina and S. yunnana should perhaps be transferred to the genus Dothiorella.

Known distribution: Iran, Italy, Netherlands, New Zealand, Norway, Poland, Portugal, Serbia, Spain, Sweden, UK (Great Britain), Ukraine, the USA (California, Florida, Oregon, Washington) (Farr and Rossman 2018). GenBank numbers: ITS = MH571673, TEF1a = MH628155. Notes: Dothiorella sarmentorum was introduced by Phillips et al. (2005). This species is a cosmopolitan distribution including many economical important trees (Phillips et al. 2005, 2013; Dissanayake et al. 2017). We isolated D. sarmentorum from Platycladus orientalis (Cupressaceae) for the first time (Farr and Rossman 2018). The morphological characters such as conidia shape, size and colour are similar to the type as described. However, we could not obtain a living culture from the isolated 123 spores. Therefore, the morphology of the species is based only on characters on the host. Phylogenetic analyses of a combined ITS and TEF1-a sequence dataset (Fig. 48) show that our isolate (MFLU 16-1627) clusters with the type strain of D. sarmentorum (IMI63581b) and strain CBS 115038. Sphaeropsis Sacc. Sphaeropsis was introduced by Saccardo (1880b) to accommodate diplodia-like taxa and is typified by S. visci (Alb. & Schwein.) Sacc. with Phaeobotryosphaeria sexual morph (Phillips et al. 2008, 2013; Dissanayake et al. 2016; Wijayawardene et al. 2017a). Sphaeropsis has a cosmopolitan distribution on various hosts (Farr and Rossman 2018). The genus is characterized by pseudothecial, brown to black, uni-loculate ascomata, thick endotunica, bitunicate asci, with cellular pseudoparaphyses, brown, aseptate ascomata and asexual morph forms with stromatic conidiomata, with paraphyses and oval, oblong or clavate, aseptate conidia (Phillips et al. 2013). More than 600 species are listed under Sphaeropsis in Index Fungorum (2019). However, Phillips et al. (2013) re-circumscribed the genus and only five species were accepted based on morphological characteristics of the sexual and asexual morph connections and phylogenetic evidence (Phillips et al. 2008, 2013; Doilom et al. 2015, 2017; Dissanayake et al. 2016; Wijayawardene et al. 2017a).

Scale bars c, d = 20 lm, e–h = 10 lm undifferentiated hyphae, or on short conidiophores. Conidial filament curved, sinuous or irregularly coiled, multiseptate, light olivaceous brown to mid brown, slightly to strongly constricted at the septa; groups of conidia often appear compactly intertwined, forming irregularly shaped masses of cells. Type species: Parazalerion indica Madrid, Gené & Cano Notes: Parazalerion is introduced as a novel monotypic conidial genus of Ascomycota. Morphologically, it resembles the marine genus Zalerion R.T. Moore & Meyers (Sordariomycetes, genera incertae sedis) in the production of irregularly coiled, dematiaceous, multi-septate conidia which often form knots of cells (Ellis 1976; Goos 1985; Campbell et al. 2005). The new genus, however, was found in a terrestrial habitat and is phylogenetically related to Spirosphaera minuta Hennebert (Fig. 53), which belongs in Dothideomycetes, relatively close to Microthyriaceae (Voglmayr et al. 2011). Furthermore, knots of cells originate from a single conidial filament in Zalerion, whereas in Parazalerion they originate from the intertwining of groups of conidia (Fig. 54). This particular development of knots of cells also distinguish Parazalerion from other similar genera, including Cirrenalia Meyers & 123 Fungal Diversity R.T. Moore, Cumulospora I. Schmidt, Glomerulispora Abdel-Wahab & Nagah., Halazoon Abdel-Aziz et al., Hiogispora Abdel-Wahab & Nagah., Hydea K.L. Pang & E.B.G. Jones, Matsusporium E.B.G. Jones & K.L. Pang, Moheitospora Abdel-Wahab et al., Moleospora AbdelWahab et al. and Moromyces Abdel-Wahab et al. (Ellis 1971; Abdel-Wahab et al. 2010). The LSU-based phylogenetic tree demonstrates that Parazalerion is phylogenetically clearly distinct from those hyphomycete genera (Fig. 53). The closest match in the BLASTn search with ITS ? LSU sequences of Parazalerion indica strain CBS 125443 is Spirosphaera minuta strain CBS 476.66 (GenBank no. HQ696659, 92% similarity, 92% query coverage). In our study, Spirosphaera minuta and Parazalerion indica appeared as sister taxa in the LSU-based phylogenetic tree (Fig. 53) and this relationship received 97% bootstrap support. Since the type species of Spirosphaera, S. floriformis Beverw., is a phylogenetically distant species belonging to Helotiales (Voglmayr et al. 2011), Spirosphaera minuta apparently needs to be reallocated to a different genus. Its definitive phylogenetic position deserves further study, but the fungus is also clearly different from Parazalerion. It occurs on submerged plant material and produces more or less globose conidia formed by a complexly coiled hyaline, branching filament (Hennebert 1968). Spirosphaera is a polyphyletic genus that needs to be revised. Another member of this genus, S. cupreorufescens Voglmayr is a member of Pleosporales (Voglmayr et al. 2011) and also needs to be segregated from Spirosphaera sensu stricto.

Muyocopronales Mapook et al. Muyocopronaceae K.D. Hyde Muyocopronaceae was invalidly introduced by Luttrell (1951) [as ‘Myiocopronaceae’], and is typified by Muyocopron Speg. with M. corrientinum Speg. as the type species. The genus was introduced to accommodate epiphytic fungi, characterized by black, superficial, dimidiatescutate, subcarbonaceous, ostiolate ascomata, without mycelium and bitunicate, ovoid to obclavate asci, containing subglobose to ellipsoidal, hyaline ascospores (Mapook et al. 2016; Tibpromma et al. 2016). Muyocopron has long historical discussion of its taxonomic placement (Saccardo 1883a; von Arx and Müller 1954, 1975; Eriksson and Hawksworth 1993; Lumbsch and Huhndorf 2007; 2010), until Hyde et al. (2013) re-defined the family Muyocopronaceae to accommodate Muyocopron. Mapook et al. (2016) introduced the order Muyocopronales to accommodate this family based on molecular data coupled with morphological characteristics. Only Muyocopron is accommodated in the family with more than 60 epithets listed (Hyde et al. 2013; Mapook et al. 2016; Tibpromma et al. 2016; Wijayawardene et al. 2018a; Index Fungorum 2019). In this study, a new host and geographical records of Muyocopron lithocarpi Mapook et al. is reported (Figs. 55, 56). Muyocopron Speg.

Barr We follow the latest treatment and updated accounts of Tubeufiaceae in Brahmanage et al. (2017), Chaiwan et al. (2017), Liu et al. (2018), Lu et al. (2018a, b), Phookamsak et al. (2018), Tibpromma et al. (2018) and Jayasiri et al. (2019). There are 27 genera accommodated in this family based on molecular data coupled with morphological characteristics (Lu et al. 2018b; Tibpromma et al. 2018; Wijayawardene et al. 2018a; Jayasiri et al. 2019). In this study, a new species Pseudohelicomyces menglunicus is introduced from a rotten seed coat in Yunnan, China (Fig. 57). Pseudohelicomyces Y.Z. Lu et al. We follow the latest treatment and updated accounts of Pseudohelicomyces in Lu et al. (2018b) and Jayasiri et al. (2019). Pseudohelicomyces menglunicus J.F. Li, Phookamsak & K.D. Hyde, sp. nov. Index Fungorum number: IF555770; Facesoffungi number: FoF05763, Fig. 58 Etymology: The specific epithet ‘‘menglunicus’’ refers to the Menglun Town, Xishuangbanna, Yunnan, China, where the holotype was collected. Holotype: KUN-HKAS 85795 Saprobic on seed coat. Sexual morph Undetermined. Asexual morph Mycelium immersed on the substrate, composed of septate, branched, smooth, thin-walled, subhyaline to dark brown hyphae. Conidiophores (106–)130– 220 9 9–13(–13.5) lm, macronematous or micronematous, paler towards the apex, hyaline to light brown, thinwalled, smooth, septate, branched, straight or flexuous, cylindrical, tapering towards the apex. Conidiogenous cells (20–) 23.5–32(–36) 9 (4–)4.5–5.5(–6) lm ( x = 4.5 9 5.3 lm, n = 10), holoblastic, integrated, intercalary and sometimes terminal, determinate or sympodial, occasionally small and discrete, denticulate, denticles cylindrical, often narrow, hyaline, smooth. Conidia (18–)20–33(–34) 9 (21.5–)25– 30(–40) lm ( x = 22.5 9 27.2 lm, n = 20), pleurogenous or acropleurogenous, solitary, simple, subhyaline to paler yellowish brown, septate, slightly constricted at the septa, planate to cochleate, smooth, thin-walled, hygroscopic. Culture characteristics: Conidia germinating on PDA within 14 h and germ tubes produced from all cells. Colonies growing on PDA, hairy, brown to dark brown, reaching 5 mm in 15 days at 23 °C, mycelium partly superficial, partly immersed, slightly effuse, radially striate, with irregular edge, subhyaline to dark brown; conidia sporulating within 15 days on PDA. Material examined: CHINA, Yunnan Province, Xishuangbanna, on unidentified seed, 15 August 2014, J.F. Li, H-26 (KUN-HKAS 85795, holotype), ex-type living culture, MFLUCC14-0689. GenBank numbers: ITS = MK335914, SSU = MK335915, TEF1-a = MK335916. Notes: Pseudohelicomyces menglunicus resembles species of Helicosporium Nees and Neohelicosporium Y.Z. Lu et al. in morphological characters, but is obviously unique in conidiophores and conidia. Pseudohelicomyces menglunicus differs from Helicosporium and Neohelicosporium species in having flexuose, branched and hyphae-like conidiophores, and smooth-walled conidia. In the phylogenetic analysis (Fig. 57), P. menglunicus forms a separated lineage, sister to P. aquaticus Y.Z. Lu et al. with moderate support (76% ML and 0.97 BYPP). Jayasiri et al. (2019) introduced a new sexual morph species, P. quercus Jayasiri et al. on fruit of Quercus sp. from Thailand. The species also formed a clade with P. aquaticus and P. menglunicus (pre-analysis, data not shown). A comparison of ITS and TEF1-a nucleotide bases shows that P. menglunicus differs from P. quercus in 37/569 bp (6.5%) of ITS and 28/912 bp (3.1%) of TEF1-a. Hence, P. menglunicus is introduced as a new asexual morph species. Class Eurotiomycetes O.E. Erikss. & Winka We follow the latest treatment and updated account of Eurotiomycetes in Gueidan et al. (2014) and Geiser et al. (2015). The outline and notes of the genera in Eurotiomycetes was provided by Wijayawardene et al. (2017a, 2018a). Subclass Chaetothyriomycetidae Doweld Chaetothyriales M.E. Barr Cyphellophoraceae Réblová & Unter. Cyphellophoraceae was introduced by Réblová et al.

The original isolate numbers and GenBank accession numbers of LSU sequences are noted after the species names. Ex-type strains are indicated in bold which was isolated from human skin in Switzerland. Taxa have been reported as pathogens or endophytes on plants, or as soil borne, as well as infection on humans and animals (i.e., nails and skin) (Réblová et al. 2013; Feng et al. 2014; Gao et al. 2015; Yang et al. 2018a). Twenty-six epithets are listed in Index Fungorum (2019) with 23 possible species are accepted in this genus. Cyphellophora G.A. de Vries Most Cyphellophora species have been reported in their asexual morph. However, Yang et al. (2018a) reported the sexual morph of Cyphellophora on living leaves of Alnus nepalensis D. Don (Betulaceae) from China for the first time.

Index Fungorum number: IF556179; Facesoffungi number: FoF05712, Fig. 60 Etymology: The specific epithet ‘‘filicis’’ (Latin: fern) refers to the host, from which the holotype was collected. Holotype: KUN-KHAS 102220 Saprobic on dead fronds of a fern, without dark superficial hyphae, appearing as black dots on host surface. Sexual morph Ascomata 40–60 lm high, 55–75 lm diam., immersed in host tissue, becoming erumpent, solitary, subglobose to globose, dark brown, uni-loculate, glabrous, ostiolate, with minute papilla.

Ascospores (15–)17– 20(–22) 9 (3–)4–5(–6) lm ( x = 18.6 9 4.7 lm, n = 30), overlapping 2–3-seriate, hyaline, ellipsoidal to fusiform, inconspicuously 3-septate, not constricted at the septa, narrowly round at the ends, sometimes curved at the middle, with a guttule in each cell. Asexual morph Undetermined. Culture characteristics: Colonies on PDA reaching 34–36 mm diam. after 3 weeks at 20–25 °C, colonies circular, dense, flat, slightly raised, surface dull, with edge entire, woolly to velvety; from above, dark grey at the margin, white-grey at the centre, separating from the margin by convex, concentric ring; from below dark greenish at the margin, with green yellowish at the centre; not producing pigmentation in agar. Material examined: THAILAND, Chiang Rai Province, Doi Pui, on dead fronds of a fern, 2 February 2017, R. Phookamsak, DP002 (KUN-KHAS 102220, holotype), extype living culture, KUMCC 18-0144 (DP002A), KUMCC18-0145 (DP002B). GenBank numbers: ITS = MK404056, LSU = MK404052, SSU = MK404054 (KUMCC 18-0144); ITS = MK404057, LSU = MK404053, SSU = MK404055 (KUMCC18-0145). Notes: The phylogenetic tree (Fig. 59) shows that Cyphellophora filicis is closely related to a fungus in Chaetothyriales (T222) that is associated with ants nest and their runway galleries (Nepel et al. 2014). It is also related to C. fusarioides (B. Sutton & C.K. Campb.) Decock, C. laciniata G.A. de Vries, C. suttonii (Ajello et al.) Decock and C. vermispora A. Walz & de Hoog, but as a distinct new species in Cyphellophora (Fig. 59). We could not compare morphological characters of our new species and those Cyphellophora species due to the fact that C. filicis is 123 Fungal Diversity Fig. 55 RAxML tree based on a combined LSU and SSU sequence dataset.

The first record of the sexual characters in Cyphellophora (C. jingdongensis) was provided by Yang et al. (2018a). However, C. jingdongensis differs from C. filicis in growing on honey dew excretions from insects, with dark superficial mycelium, scattered, superficial ascomata, without short necks, ellipsoidal to cylindrical asci and 1–3septate fusoid ascospores. Thus, we introduce C. filicis as a new species based on the sexual morph characters and phylogenetic evidence (Figs. 59, 60). Herpotrichiellaceae Munk The family Herpotrichiellaceae was introduced by Munk (1953) and placed in the order Chaetothyriales (Barr 1976; Réblová et al. 2013; Gueidan et al. 2014; Wijayawardene et al. 2018a). The family is characterized by small, superficial, inconspicuous, setose ascomata, fissitunicate asci and greenish grey to brown, phragmosporous or dictyosporous ascospores (Munk 1953; Hyde et al. 2016). Species of this family can be saprobes on decaying wood, bark and leaves and are also found as pathogens on humans and living plants, as well as parasites on fungi or lichens worldwide (Crous et al. 2007b; Untereiner et al. 2011; Wijayawardene et al. 2017a). Fifteen genera are accepted in this family (Wijayawardene et al. 2018a). Capronia Sacc. Capronia is a poorly understood ascomycete genus characterized by very small, setose ascomata, lacking paraphyses, fissitunicate asci, and septate, or muriform, hyaline or pigmented ascospores (Munk 1957a, b; Müller et al. 1987; Untereiner et al. 2011; Friebes 2012). Species of this genus are associated with a wide range of hosts as saprobes on rotting wood or bark and decaying stems and leaves of herbaceous plants, or pathogenic on plants as well as parasites on other fungi, or lichens (Untereiner 2000; Untereiner et al. 2011; Wijayawardene et al. 2017a). We introduce a new species Capronia camelliae-yunnanensis, collected on Camellia yunnanensis in China (Figs. 61, 62). Capronia camelliae-yunnanensis M. Raza, Z.F. Zhang & L. Cai, sp. nov. Index Fungorum number: IF555356; Facesoffungi number: FoF04884, Fig. 62 Etymology: Named after the epithet of Camellia yunnanensis, the host of which the holotype was collected. Holotype: HMAS 255435 Saprobic on Camellia yunnanensis. Sexual morph Ascomata 175–200 lm high, 215–220 lm diam., scattered or clustered, solitary, superficial on decorticated bark of host, with papilla, globose to subglobose, lodged on a basal subiculum, which form loose hyphae penetrating the underlying cells, setose around the surface of the wall, setae up to 30 lm long. Peridium 20–30 lm wide, thickwalled, of equal thickness, composed of several layers of small, pseudoparenchymatous cells, inner layers comprising hyaline cells, arranged in a textura angularis, outer layers comprising brown to dark brown becoming blackened cells of textura prismatica. Hamathecium composed of dense, 3–5 lm wide, broad, filamentous paraphyses with indistinct septate, not constricted at the septa, embedded in a gelatinous matrix. Asci (51–)57–78(–80) 9 (5–)6–10(– 12) lm ( x = 67.8 9 8.7 lm, n = 40), 8-spored, bitunicate, fissitunicate, broadly cylindrical, short pedicellate with knob-like pedicel, apically broad rounded, with a blunt ocular chamber. Ascospores (10–)13–17(–19) 9 (2–)3– 5 lm ( x = 15.1 9 4.5 lm, n = 40), overlapping 1–3-seriate, hyaline and aseptate when young, becoming light brown to yellowish, ellipsoidal to fusiform, muriform, with 3–7 transverse septa and 1–3 longitudinal septa, slightly constricted at the septa, smooth-walled. Asexual morph Undetermined. Culture characteristics: Colonies on PDA reaching 15–20 mm diam. after 5 weeks at 25 ± 2 °C, colonies circular, umbonate, smooth to woolly with entire edge, velvety, smooth at the margin; from above, light green at the fruiting zone, whitish green at the productive zone and ageing zone; from below, light green at the fruiting zone, dark green to blackish at the productive zone, grey at the ageing zone; not producing pigmentation in PDA.

Among the sections of Penicillium, section Citrina was introduced by Houbraken and Samson (2011) based on phylogenies derived from RPB1, RPB2, Tsr1, and Cct8 sequence data. Currently, section Citrina contains 40 species (Houbraken et al. 2011; Visagie et al. 2014a, b). Members of section Citrina are found in soil, leaf litter, indoor environments, and food (Pitt 1979; Pitt and Hocking 2009; Samson et al. 2010). The species of section Citrina are characterized by the production of relatively small conidia, symmetrically biverticillate conidiophores and ampulliform phialides. They are also known for their ability to produce a variety of extrolites, including mycotoxins, citrinin, and citreoviridin (Houbraken et al. 2011). While, evaluating fungal diversity in soil samples in Korea, a new species was isolated and is described here based on morphological characteristics and phylogenetic analyses (Fig. 63). Subclass Eurotiomycetidae Geiser & Lutzoni Eurotiales G.W. Martin ex Benny & Kimbr. Trichocomaceae E. Fisch. The family Trichocomaceae was introduced by Fischer (1897). This is a large saprobic family in nature with the most well-known genera including Aspergillus P. Micheli ex Haller, Penicillium, and Paecilomyces Bainier. Species belonging to this family have the ability to produce secondary metabolites (mycotoxins or extrolites), and enzymes (Pitt and Hocking 2009; Samson et al. 2010; Houbraken et al. 2011). Penicillium Link The genus Penicillium was first described by Link in 1809. Species of Penicillium are well known and found abundantly in the soil, air, indoor environments and in contaminated foods (Frisvad and Samson 2004; Samson et al. 2010). According to Houbraken and Samson (2011), the genus Penicillium was divided into four subgenera: Penicillium dokdoense Hyang B. Lee & T.T.T. Nguyen, sp. nov.

Asexual morph Hyphomycetous. Colonies grow slowly on CYA, reaching 23.5–26 mm diam. at 25 °C in 7 days, grey-green, floccose in centre, soluble pigment absent, margin entire; reverse yellowish white with yellow-brown in centre. Conidiophores mostly biverticillate, sometimes monoverticillate, or divaricate, stipes smooth, vary greatly in length, septate, 2–3.5 lm wide. Metulae cylindrical, 2–5 per stipe, 10.5–17.5 9 2.5–4.2 lm. Phialides ampulliform, 3–9 per metula, 6.7–11.5 9 2–3.5 lm. Conidia roughened, globose to subglobose, or ellipsoidal, and dark blue-green, 2–3.5 9 2–3 lm. Culture characteristics: The isolate grew over a wide range of temperatures with varying growth rates on MEA, CYA, YES and CREA. The average growth rates of CNUFC-DDS11-1 on MEA, CYA, YES, and CREA medium at 25 °C were 34.5, 24.5, 22, and 14.5 mm per 7 days, respectively. Optimal growth was observed around 25 °C, slow growth was observed below 10 °C, and no growth at 37 °C.

Maximum likelihood bootstrap support values greater than 50% and Bayesian posterior probabilities greater than 0.75 BYPP are indicated on the notes. The new isolate is in blue. The tree is rooted with Vonarxia vagans (CBS 123533) Collection for Type Cultures (KCTC, Daejeon, Korea), extype living culture, JMRC:SF:013606. GenBank numbers: ITS = MG906868, TUB2 = MH243037, CMD = MH243031 (CNUFC-DDS11-1); ITS = MG906869, TUB2 = MH243038, CMD = MH243032 (CNUFC-DDS11-2). Notes: The data from combined sequence analyses of the two loci (Fig. 63) reveal that Penicillium dokdoense, P. terrigenum Houbraken et al., P. cf. terrigenum and P. copticola Houbraken et al. are closely related. Penicillium dokdoense shares several similarities with P. terrigenum as its growth on CREA is poor with no acid production, but this species differs from P. terrigenum in terms of reverse colour on CYA and YES, and colony features on CYA. Furthermore, P. dokdoense produces globose to subglobose, or ellipsoid conidia and biverticillate, monoverticillate, or divaricate conidiophores, in contrast to the mostly ellipsoid conidia and biverticillate sporangiophores of P. terrigenum. Penicillium terrigenum and P. copticola grew at a similar range of temperatures from 25 °C to 30 °C, whereas P. dokdoense grew slowly. Penicillium dokdoense grows and sporulates at 35 °C, while, P. cf. terrigenum does not grow above 30 °C. At 5 °C, P. dokdoense and P. copticola were both capable of growth, whereas P. terrigenum was not. When grown on CYA, colonies of P. dokdoense are weakly wrinkled, while colonies of P. terrigenum are strongly wrinkled. The results of morphological and comparative sequence analyses of P. dokdoense indicate that it is a distinct species from P. terrigenum, P. cf. terrigenum, and P. copticola. Thus, P. dokdoense is proposed. Class Lecanoromycetes O.E.

Micropeltidaceae Clem. & Shear The family Micropeltidaceae was introduced by Clements and Shear (1931) as ‘Micropeltaceae’ and is typified by Micropeltis Mont. with M. applanata Mont. as the type species. The family comprises foliar, biotrophic epiphytes, which are mostly found on the lower leaf surface as small black dots. Micropeltidaceae species are characterized by Lecanoromycetes, families incertae sedis 123 Fungal Diversity superficial, flattened, black-blue or greenish to black thyriothecia, easily removed from the host surface, poorly developed at the base, the wall comprising interwoven hyphae, with a central ostiole and ascospores are septate and hyaline (Clements and Shear 1931; Wu et al. 2011; Hyde et al. 2013; Hongsanan et al. 2015; Hongsanan and Hyde 2017). Micropeltis phetchaburiensis sp. nov. is introduced based on its morphological characteristics coupled with phylogenetic analyses of a combined LSU and SSU sequence dataset (Fig. 65). The new species was collected from living leaves in Thailand. Micropeltis Mont.

Dayarathne, KLAP011 (MFLU 18-1408, holotype; HKAS102010, isotype). GenBank numbers: LSU = MH656405, SSU = MH656406. Notes: Micropeltis phetchaburiensis resembles M. dendrophthoes Hongsanan & K.D. Hyde and M. zingiberacicola H.X. Wu & K.D. Hyde in forming broadly cylindrical to fusiform asci and hyaline, clavate, septate ascospores (Wu et al. 2011; Hongsanan et al. 2015). Micropeltis phetchaburiensis can be distinguished from M. dendrophthoes and M. zingiberacicola in having 3-septate ascospores with the 4 cells being equal in length and width, while ascospores of the other two species are 4–5-septate and enlarged at the first cell and relatively longer lower end cells. In our phylogenetic analyses of a combined LSU and SSU sequence dataset, M. phetchaburiensis forms a basal lineage to M. dendrophthoes and M. zingiberacicola with moderate bootstrap support (97% ML and 93% MP; Fig. 65). 123 Class Leotiomycetes O.E. Erikss. & Winka We follow the latest treatment and updated accounts of Leotiomycetes in Zhang and Wang (2015), Jaklitsch et al. (2016a) and Wijayawardene et al. (2018a) for the taxonomic outline of this class. Helotiales Nannf. ex Korf & Lizoň Fungal Diversity Lachnaceae Raitv. Raitviir (2004) raised Nannfeldt’s tribe Lachneae (fam. Hyaloscyphaceae; Nannfeldt 1932) to the family level and designated Lachnum Retz. as the type genus. Han et al. (2014) showed that Lachneae formed a monophyletic lineage within Hyaloscyphaceae sensu lato, justifying the existence of Lachnaceae. Jaklitsch et al. (2016a) and Wijayawardene et al. (2018a) recognize 16 genera in this family. Phylogenetic relationships of selected lachnoid taxa were studied previously by Cantrell and Hanlin (1997) and Hosoya et al. (2010). We introduce a new monospecific genus Velebitea in the family Lachnaceae based on microscopic and macroscopic features. Velebitea I. Kušan, Matočec & Jadan, gen. nov. MycoBank number: MB827753; Facesoffungi number: FoF05713 Etymology: Named after the mountain, Velebit, on which it was collected. Sexual morph Ascomata apothecial, comparatively robust and medium sized, superficial, stipitate, solitary or gregarious, deeply cupulate when young, becoming shallowly cupulate to ± plate-shaped. Hymenium creamy whitish, yellowish with age, margin upright, covered with long whitish hairs, as well as whole excipulum and stipe throughout the base, excipulum paler than hymenium, stipe centrally attached, tapering towards the base, base brownish. Subhymenium equally thick or thicker than medullary or ectal excipulum, composed of hyaline textura epidermoidea-intricata, in living state clearly discerned from the medulla. Marginal texture of hyaline textura porrectaprismatica, often with abundant yellow resinous inclusions, beset with ± tidily organized cylindrical marginal hairs which are always clearly separated from excipular ones by a small hairless area just at the point of hymenial base level, individual hairs ± straight, multi-celled, markedly shorter than excipular flank hairs, apical cell cylindricobtuse to subclavate, walls thin and hyaline, cells without refractive content when in living state, only basal 1–2 cells with firmly attached KOH resistant granules, not stainable in cotton blue, with additional abundant loosely attached KOH soluble pale yellowish resinous granules, no crystals. Medullary excipulum composed of hyaline densely woven textura intricata, producing small hyaline crystalloid particles with age, sometimes having abundant yellow resinous inclusions, intercellular spaces overall slightly gelified. Ectal excipulum composed of single layer of textura prismatica with cells running ± parallel to the surface, walls somewhat thickened, especially in some outermost cells, basal areas regularly with highly refractive golden yellow resinous accumulations; surface beset with very untidily intricately organized flexuous excipular hairs, multi-celled, longer than marginal hairs, walls thin, with apical localized thickenings in some hairs, only basal 1–2 cells with firmly attached KOH resistant granules, regularly supplemented by KOH soluble loosely attached pale yellowish granules, surface irregularly embedded in abundant gel plaques clearly stained lilac in brilliant cresyl blue, in cotton blue walls not cyanophilic, yellow resinous accumulations dissolved. Overall texture and hairs in Lugol’s solution without any amyloid reactions, all yellow resinous accumulations in texture are rapidly soluble in KOH. Paraphyses cylindrical, apically obtuse, straight, not branching in the upper part, apical and often subapical cells contain hyaline non-refractive vacuoles. Asci 8-spored, elongated cylindrical-deltoid, apex conical obtuse, protruding above paraphyses at full maturity, arising from simple septate ascogenous cells, in Lugol’s solution apical apparatus moderately euamyloid of Calycina-type. Ascospores elongated fusoid, ± straight to bent, bilaterally symmetrical, always 1-celled in full maturity, smooth, hyaline, poles tapered to sub-obtuse, eguttulate or with several minute guttules, uninucleate, the remaining sporoplasm regularly occupied by several conspicuous non-refractive vacuoles, when freshly ejected without sheath; in Lugol’s solution cytoplasm without glycogen accumulations. Asexual morph Undetermined. Type species: Velebitea chrysotexta I. Kušan, Matočec & Jadan Notes: A data matrix for alignment was constructed to determine the phylogenetic position of Velebitea chrysotexta within Lachnaceae and also to test phylogenetic proximity to Hyaloscyphaceae (Amicodisca virella (P. Karst.) Huhtinen), and Tetracladium spp. Phylogenetic analysis (Fig. 67) included the ITS and LSU sequences generated from the holotype of Velebitea chrysotexta and other related sequence data, retrieved from GenBank as well as a newly sequenced collection of Neodasyscypha cerina (Pers.) Spooner (CNF 2/10442; ITS = MH886408, LSU = MH886412) which was collected from fallen decorticated branch of Fagus sylvatica L. in Croatia. Sequences of Hymenoscyphus fructigenus (Bull.) Gray were used as an outgroup taxon. Maximum likelihood analysis of the concatenated ITS and LSU alignment was performed by MEGA7 (Kumar et al. 2016), including 1361 total characters in the final dataset. The phylogeny based on concatenated analysis of ITS and LSU nests the genus Velebitea in the family Lachnaceae as a separate lineage having comparatively basal position not belonging to any of tested genera (Fig. 67). Megablast search of NCBIs GenBank nucleotide database using the ITS sequence of Velebitea chrysotexta (CNF 2/10072, GenBank no. MH886407) shows that the closest hits belong to Lachnellula spp. with the similarities between 89% and 91% similarities. Lachnellula P. Karst. is a genus in Lachnaceae, strictly confined to coniferous hosts 123 Fungal Diversity (Dharne 1965). On the other hand, the closest hits using the LSU sequence (GenBank no. MH886411) are Tetracladium furcatum Descals (GenBank no. EU883428; similarity = 907/1009 (90%), gaps = 45/1009 (4%)) and T. maxilliforme (Rostr.) Ingold (GenBank no. EU883429 and EU883430; both with similarity = 903/1008 (90%), gaps = 43/1008 (4%)). Tetracladium De Wild. is an aquatic hyphomycete genus (Letourneau et al. 2010) classified as Helotiales, incertae sedis (Wijayawardene et al. 2017a, 2018a), but phylogenetic affinity is close to Helotiaceae, and Hyaloscyphaceae (Wang et al. 2015). Certain similarity exists between Velebitea and Tetracladium in their ecological preference to a colder climate; the sexual morph of Velebitea lives in subalpine forests with beech (Fagus) while some members of the genus Tetracladium were recorded in cold snow-covered soil in a glacier zone (Kuhnert et al. 2012). Together with the genus Dasyscyphella Tranzschel, Velebitea is different from all other genera in the family Lachnaceae by partially granulated hyaline hairs. Dasyscyphella is clearly polyphyletic (Hosoya et al. 2010; this study) and therefore in need of taxonomic rearrangement. Since the type species of the genus Dasyscyphella, D. cassandrae Tranzschel is not present in public DNA sequence databases, we included all other available species from this genus in our phylogenetic analysis because species currently ascribed to Dasyscyphella display highest similarity to our material based on non-molecular data. The polyphyly of the genus Dasyscyphella could be in line with wide diversity of certain non-molecular features that may play important role in future species distinguishing at generic level, such as existence of hair crystals, resinous exudates and its microchemical properties, hair wall granulation degree, hamathecial features, details in ecology, apothecial development and anatomy, despite of high similarity among many of species in terms of ‘‘standard’’ microscopical characters (e.g. spore and ascus shape/measurements). Many of these characters already efficiently delimitate some monophyletic lachnacean genera, viz. Capitotricha (Raitv.) Baral, Brunnipila Baral and Fig. 65 Phylogram generated from maximum likelihood (RAxML) analysis based on combined LSU and SSU sequence dataset of representative families in Lecanoromycetes.

Scale bars c = 100 lm, d, e = 50 lm, f, g, k = 20 lm, h–j = 10 lm Lachnellula. Dasyscyphella cassandrae, the type species of the genus, differs strikingly from Velebitea chrysotexta by very elongate flexuous-cylindric, septate ascospores, overall absence of KOH soluble resinous lumps and, together with all other known species currently ascribed to the genus Dasyscyphella in having only the apical (rarely also subapical) smooth hair cell. Whereas, hairs in V. chrysotexta are smooth except in basal 1–2 cells. Hairs in 123 Fungal Diversity D. cassandrae (as well as in many other species) are longer at the margin than on excipular flanks, quite opposite in V. chrysotexta. A number of species currently ascribed to a genus Dasyscyphella have hairs bearing conspicuous calcium oxalate crystals and/or crystal druses (such as D. nivea positioned well aside from V. chrysotexta in our phylogenetic analysis) that are completely lacking in V. chrysotexta. Nearly all species currently ascribed in the genus Dasycyphella have either lanceolate or cylindricalpointed paraphyses (as in D. cassandrae). There are however some species of the genus Dasyscyphella that according to Raitviir (2002), also Dennis (1949), produce resinous pigments comparable to Velebitea chrysotexta: Dasyscyphella claviculata (Velen.) Baral & Svrček, D. crystallina (Fuckel) Raitv., D. rubi Raitv., D. conicola (Rehm) Raitv. & Arendh., D. nivea (R. Hedw.) Raitv., D. tamajonica (Raitv. & R. Galán) Raitv. (all producing calcium oxalate crystals, mostly having different ecology), D. mughonicola (Svrček) Raitv. & Arendh. (whose asci arising from croziers, coniferous substrate), D. patuloides Raitv. & R. Galán (producing hyaline resin, asci arising from croziers, having phyllophilous ecology) and D. sulphuricolor (Peck) J.H. Haines (producing brownish resin that reacts vinaceous with KOH). Much work is still to be done to uncover true phylogenetic affinities of a number of species currently accommodated in Dasyscyphella which might belong to severally phylogenetic lineages representing separate genera.

Erikss. & Winka We follow the latest treatment and updated accounts of Pezizomycetes in Jaklitsch et al. (2016a), Ekanayaka et al. (2018) and Wijayawardene et al. (2018a). Pezizales J. Schröt. Pezizaceae Dumort. The family Pezizaceae was introduced by Dumortier (1829) with Peziza Fr. as the type genus. A systematic overview of the family was recently given by Jaklitsch et al. (2016a) who recognized 32 genera in this family. Ekanayaka et al. (2018) reviewed the families in the class Pezizomycetes and outlined 45 genera names belonging to Pezizaceae, including also some taxa synonymized by other authors. Sarcopeziza Loizides et al. A new genus in the Pezizaceae, Sarcopeziza Loizides et al. was recently erected (Agnello et al. 2018) to accommodate a single species, Peziza sicula Inzenga (Inzenga 1869). This species was previously typified and treated by Agnello et al. (2013) and Agnello et al. (2015). Since the original description of Inzenga (1869) and the modern presentations by Agnello et al. (2013) and Agnello et al. (2018) are not fully adequate and accurate for further advancement in taxonomy of the group, a more detailed redescription of microscopical features of Sarcopeziza sicula is provided here, based on careful cyto- and histochemical analyses.

Ascospores (13.2–)13.4–15.1–16.1 (–16.7) 9 (8.1–)8.3–8.9–10, Q = 1.48–1.57–1.76(–1.77) (n = 50, in cotton blue), hyaline, ellipsoid, sometimes broadly oblong, radially symmetrical, with rounded poles, 1-celled, seemingly smooth under immersion lens when in water mount, many spores (especially when outside of the asci) slightly roughened in cotton blue but markings are not cyanophilic, measuring below 0.2 lm high and up to 0.3 lm diam., mature spores initially with multiguttulate pattern, lipid bodies, when still not coalesced 0.3–1.5 lm diam., lipid bodies in dead spores coalesced in various degree up to maximal, uni-guttulate stage (visible only in water mount), uninucleate (visible in spores having lipids in multi-guttulate pattern), wall 3-layered, 0.7–0.8 lm thick; in Lugol’s solution without glycogene accumulations; in KOH wall stable (not loosening); in cotton blue perispore weakly cyanophilic, wall not loosened, de Bary bubbles present in some mature spores, lipid bodies completely masked, sporoplasm unstained; in acetocarmine nucleus not differentially stained, only submature spores with weakly stained nucleus, perispore not loosened. Asexual morph Undetermined. 123 Material examined: ITALY, Province of Brindisi, San Pancrazio Salentino, San Antonio alla Macchia, 40°250 0000 N, 17°500 0000 E, 59 m a.s.l., on bare and mossy soil in a sunny Pinus halepensis Mill. forest with Eryngium campestre L. and Poaceae, 7 February 2008, A. Delle Donne and C. Agnello (MCVE 25877, epitype). Habitat and phenology: On sandy or calcareous soils in frame of dry Mediterranean thickets (mostly dominated by Cistus spp.) and grasslands and parks, sometimes in vicinity of thermophilic Pinus spp., Pyrus spp. and Olea europea in thermo-Mediterranean bioclimatic belt, fruit bodies appear between January and April. Known distribution: Cyprus, Greece, Israel, Italy, Spain and Tunisia. GenBank numbers ITS = MH886405, LSU = MH886409 (MCVE 25877, epitype). Notes: A data matrix for alignment was constructed to show a phylogenetic position of Sarcopeziza sicula within Pezizaceae, with a special emphasis on the genus Peziza. Phylogenetic analysis (Fig. 73) included the ITS and LSU sequences generated from the epitype collection of Sarcopeziza sicula and other related sequences retrieved from GenBank as well as a newly sequenced collection of Adelphella babingtonii (Berk. & Broome) Pfister, Matočec & I. Kušan (CNF 2/9430; ITS = MH886406, LSU = MH886410). Ascobolus crenulatus P. Karst. was used as an outgroup taxon. The maximum likelihood analysis of a combined ITS and LSU sequence dataset was conducted in MEGA 7 (Kumar et al. 2016) with a total of 1462 positions in the final dataset. The phylogeny based on concatenate analysis of ITS and LSU nested the genus Sarcopeziza in the family Pezizaceae, in a species group along with Eremiomyces Trappe & Kagan-Zur, Hapsidomyces venezuelensis J.C. Krug & Jeng and Peziza phyllogena Cooke, next to the Terfezia-Tirmania, P. depressa, P. saniosa and Peziza ostracoderma clades (Fig. 73). Eremiomyces echinulatus (Trappe & Marasas) Trappe & Kagan-Zur and E. magnisporus G. Moreno et al. cluster with high support with Sarcopeziza sicula showing a high level of genetic similarity. Sarcopeziza sicula demonstrates a distant relationship to Peziza vesiculosa Bull. and Sarcosphaera coronaria (Jacq.) J. Schröt. which are type species of the genera where it was previously combined (Inzenga 1869; Patouillard 1904), suggesting taxonomic affinity outside of those genera. Besides molecular evidence, Sarcopeziza sicula is different from Peziza sensu stricto [a core species group gathered around the type species, P. vesiculosa, cf. Hansen et al. (2001, 2002, 2005)], primarily by faintly visible, filmlike periascal mucus that is revealed by moderately diffusely amyloid reaction in iodine mounts, gradually decreasing in strength downwards.

Scale bars b = 1 cm, c–l = 10 lm from Peziza sensu stricto have opercular (apical) thick accumulation of heavily amyloid mucus giving strong ringlike amyloid reaction confined to the ascal tops. Agnello et al. (2018) define asci as diffusely amyloid along the entire length of the asci and strongly amyloid at the apex (type I, cf. Hansen et al. 2001). Judging to both the authors’ microphotograph and own observations, the type of amyloidity belongs to type III instead of type I. The fine structure of the ascus wall lacks strong apical indentation ring and lentiform operculum in Sarcopeziza sicula, characters that are constantly present in all studied species in Peziza core species group as well as in ascobolacean representatives and species of Peziza succosa and P. succosella clade (pers. data, cf. Samuelson 1978). Moreover, Sarcopeziza sicula is also different by ontogenetically and cytochemically comparatively stable multiguttulate lipid configuration in fully developed ascospores and violet-purplish in flesh. Contrary to Agnello et al. (2013, 2018), the spores in this study are recognized as multi-guttulate when fully mature and in living state whose lipids coalesce in dead state towards uni-guttulate or more rarely bi-guttulate pattern. The process of lipid body coalescence in dead spores is regularly observed throughout Ascomycota (Baral 1992). The microphotograph of ripe asci in Agnello et al. (2018, Fig. 2f), is clearly displaying multi-guttulate pattern of living and fully mature ascospores, while Fig. 2c, d in Agnello et al. (2013) resemble 123 Fungal Diversity Fig. 72 Sarcopeziza sicula. a Excipular structure (bright field). b Excipular structure (dark field). c Excipular structure, upper half with hymenium (dark field). d Excipular structure, lower half (dark field). e Subhymenium with minute crystalloid particles. f Upper medulla with minute crystalloid particles. g Upper medulla with lipid like globules. h Ectal excipulum with minute crystalloid particles. i Cortical cells with yellow cytoplasm and hyaline hyphoid outgrowths. j Subhymenium and upper medulla. k Upper medulla with largest cells. l Lower medulla. m Lower medulla with fasciculate texture. n Ectal excipulum. a, b, e, f, h in water mount, c, d, g, i–n in cotton blue.

Furthermore, the authors presumed that ascospore ornamentation is not constant character in this species. It is quite possible that ornamentation in this species is normally formed after spore ejection and extraascal dormancy. Both available ascomata from the epitype produced large number of dormant ascospores whose fine ornamentation is 123 Fungal Diversity clearly visible in lactic acid cotton blue under oilimmersion. From the genus Sarcosphaera Auersw. (its type and the only species S. coronaria), Sarcopeziza sicula is different by the absence of paraphysal internal content, different original lipid body configuration in mature ascospores (multi-guttulate vs. bi-guttulate), intensively pigmented flesh and the excipular surface, substipitate to stipitate apothecia, and lack of discernable odour (S. coronaria has somewhat chlorine scent). Agnello et al. (2018) describe the subhymenium as 150–180 lm thick layer but we detected it as very reduced and unclearly discerned tissue from the upper medulla using high contrasting techniques on a number of entire, thin sections (ranging from hymenium up to ectal excipular layer) from the epitype material. The closest pezizacean relatives of Sarcopeziza sicula revealed in our phylogenetic analysis are species of the genus Eremiomyces, Hapsidomyces venezuelensis and Peziza phyllogena (a member of the genus Peziza sensu lato). All so far produced DNA based phylogenies (along with the present one), however, clearly showed polyphyly in the genus Peziza, where numerous species attributed to the other genera (especially of hypogeous representatives) build up monophyletic clades along with certain members ascribed to a genus Peziza. Therefore, all species putatively ascribed to a genus Peziza should be carefully restudied using integrative taxonomic approach. Sarcopeziza sicula is readily recognizable from all other currently known genera in the family Pezizaceae by specific combination of macroscopical features (semi-hypogeous sarcosphaeroid apothecia with unique pigmentation), ecology (subpsammophilic and/or xeric habitats in thermo-Mediterranean zone) and microscopy, principally cytochemistry and fine structure of the asci and multi-guttulate lipid body configuration of the ascospores, characters that were proved to be informative for differentiation in Pezizaceae in a previous study (Pfister et al. 2009). There is a number of similarities in excipular structures of semi-hypogeous species Sarcopeziza sicula and peridial/glebal microscopic structures of the closest relative, hypogeous species Eremiomyces magnisporus (cf. Alvarado et al. 2011): (1) the same texture in peridia of E. magnisporus and cortical layer of ectal excipulum in S. sicula; (2) cytoplasmic pigments in peridial cells of E. magnisporus and cortical layer cells of S. sicula; (3) same texture in glebal sterile veins in E. magnisporus and medullary excipulum in S. sicula; and (4) lipid-like globules in glebal sterile vein cells in E. magnisporus and medullary excipular cells in S. sicula. The other hypogeous species Eremiomyces echinulatus which is a type species of the genus Eremiomyces, and E. innocentii Ant. Rodr. & Bordallo as well as phylogenetically close Kalaharituber pfeilii (Hennings) Trappe & Kagan-Zur (cf. Ferdman et al. 2005 and Crous et al. 2017) also possess very similar structures in peridial and glebal cells and texture. Very similar excipular texture exists in Peziza phyllogena too (pers. data) and in wider apothecial marginal area of Hapsidomyces venezuelensis (cf. Krug and Jeng 1984), two epigeous phylogenetically closest relatives. Nearly the same fine opercular structure in cotton blue mount is found in both Sarcopeziza sicula and Peziza phyllogena (pers. data). On the other hand, genera Eremiomyces and Kalaharituber Trappe & Kagan-Zur differ from Sarcopeziza sicula by their entirely hypogeous living strategy developing permanently closed stereothecia with solid gleba and producing perfectly globose coarsely aculeate ascospores. The closest apothecial representatives have different living strategy also viz. fimicolous in Hapsidomyces venezuelensis and phyllophilous in Peziza phyllogena versus terricolous-subpsammophilous in Sarcopeziza sicula. Ascal amyloidity is also different: thin but wider and moderately strong apical ring-like reactive zone exist in Peziza phyllogena extending downwards with abruptly weakened intensity (pers. data) while Hapsidomyces venezuelensis has weakly amyloid reaction over entire ascus length (Hansen et al. 2001). Hapsidomyces venezuelensis has ascospores very much resembling those of Eremiomyces (though spinulose-reticulate). While, Peziza phyllogena has ellipsoid ascospores (as in Sarcopeziza sicula), though rather coarsely sculptured by cyanophilic verrucae and higher tuberculae around the polar areas (pers. data). Class Sordariomycetes O.E. Erikss. & Winka The classification of the families in Sordariomycetes follow Maharachchikumbura et al. (2016), Hongsanan et al. (2017) and Wijayawardene et al. (2017a, 2018a). Subclass Diaporthomycetidae Senan. et al. Atractosporales H. Zhang et al. Conlariaceae H. Zhang et al. Conlariaceae was introduced by Zhang et al. (2017a) in the order Atractosporales to accommodate the freshwater genus Conlarium, with two species, C. aquaticum W. Dong et al. and C. duplumascosporum F. Liu & L. Cai. We follow the latest treatment in Zhang et al. (2017a) and the new species, C. thailandense is introduced based on morphological characteristics coupled with phylogenetic analysis of combined LSU, SSU and ITS sequence data (Fig. 74). Conlarium F. Liu & L. Cai Conlarium was introduced by Liu et al. (2012a) from a freshwater habitat in China to accommodate C. 123 Fungal Diversity Fig. 73 Maximum likelihood phylogenetic tree based on a concatenated ITS and LSU sequence dataset. Sequences recovered during this study are shown in blue and ex-type strains are in bold. The tree is rooted to Ascobolus crenulatus. Bootstrap values greater than 50% are indicated at the nodes. The bar length indicates the number of nucleotide substitutions per site duplumascosporum with sexual and asexual morphs (Liu et al. 2012a). Recently, Zhang et al. (2017a) introduced the second freshwater taxon C. aquaticum from Thailand. Holotype: MFLU 17-1711 Saprobic on dead wood in terrestrial habitat. Sexual morph Undetermined. Asexual morph Hyphomycetous. Colonies sporodochial, broadly punctiform, gregarious, raised, dark brown to black. Mycelium mostly immersed on natural substratum, comprising branched, pale brown to hyaline, smooth and thin-walled hyphae. Conidiophores absent or reduced to conidiogenous cells. Conidiogenous cells monoblastic, holoblastic, integrated, determinate, Conlarium thailandense X.D. Yu, H. Zhang & K.D. Hyde, sp. nov. Index Fungorum number: IF555288; Facesoffungi number: FoF04830, Fig. 75 Etymology: Named after the country where it was collected, Thailand 123 Fungal Diversity cylindrical, hyaline, smooth, up to 5.5 lm long. Conidia 25–45 9 17–33 lm ( x = 35.9 9 26.9 lm, n = 20), acrogenous, solitary, dry, mostly irregular, subglobose to ellipsoidal, brown to dark brown, clathrate, muriform, 4–8transversely septate, 4–6-longitudinally septate, slightly constricted at the septa, smooth and thin-walled, with a small, sub-rounded, dark brown ornamentation on the surface of each cell. Conidial secession schizolytic. Culture characteristics: Colonies on PDA, irregular in shape, reaching 10–20 mm in 6 weeks at room temperature, black from above and below, umbonate, rough, dense, edge undulate. Material examined: THAILAND, Chiang Rai Province, Mae Fah Luang University, on dead wood, 17 July 2017, S. Boonmee, DP6 (MFLU 17-1711, holotype), ex-type living culture, MFLUCC 17-2349. GenBank numbers: ITS = MH624129, LSU = MH624127, SSU = MH624128. Notes: Conlarium thailandense is similar to the asexual morph of C. duplumascosporum and C. aquaticum. They all have monoblastic, holoblastic conidiogenous cells and mostly irregular, brown, clathrate, muriform conidia (Liu et al. 2012a). However, they can be easily distinguished by the number of septa (0–2-transversely septate, 0–1-longitudinally septate in C. duplumascosporum, 6–12-transversely septate, 4–10-longitudinally septate in C. aquaticum and 4–8-transversely septate, 4–6-longitudinally septate in C. thailandense) and conidial size (15.5–35 9 11–26.5 lm in C. duplumascosporum, 45–70 9 20–57 lm in C. aquaticum and 25–45 9 17–33 lm in C. thailandense) (Liu et al. 2012a; Zhang et al. 2017a). Apart from number of septa and conidial size, a number of air-bubbles were also observed on mature conidia of C. thailandense, which have not been reported in C. aquaticum and C. duplumascosporum. Phylogenetic analyses of a combined LSU, SSU and ITS sequence alignment based on maximum likelihood and Bayesian inference show that C. thailandense is sister to C. aquaticum. A comparison of ITS pairwise indicates that C. thailandense differs from C. aquaticum in 13 base positions and is therefore novel following the guidelines of Jeewon and Hyde (2016). Diaporthales Nannf. Cytosporaceae Fr. The family Cytosporaceae was introduced by Fries (1825) and recognized a family in Diaporthales, which comprises phytopathogens and saprobes (Wehmeyer 1975; Barr 1978; Eriksson 2001; Castlebury et al. 2002). Maharachchikumbura et al. (2015, 2016) listed 13 genera under Cytosporaceae. Senanayake et al. (2017) accepted five genera, which belong to Cytosporaceae based on morphological characteristics viz. Cytospora Ehrenb., Pachytrype Berl. ex M.E. Barr et al., Paravalsa Ananthap., Xenotypa Petr. and Waydora B. Sutton. Wijayawardene et al. (2018a) listed only genera Cytospora and Waydora in Cytosporaceae. Cytospora Ehrenb. Cytospora was introduced by Ehrenberg (1818) as type genus of the family Cytosporaceae in Diaporthales (Wehmeyer 1975; Barr 1978; Eriksson 2001; Castlebury et al. 2002; Norphanphoun et al. 2017). The genus was introduced as important pathogens, which cause cankers and dieback disease on branches of a wide range of hosts worldwide (Adams et al. 2005, 2006; Hyde et al. 2017, 2018b; Norphanphoun et al. 2017, 2018). There are 630 epithets for Cytospora (Index Fungorum 2019) with an estimated 110 species in Kirk et al. (2008). Norphanphoun et al. (2017) provided a comprehensive account of the morphology and molecular background of the genus. Several new taxa have recently been introduced (Hyde et al. 2016, 2017, 2018b; Norphanphoun et al. 2017, 2018; Senanayake et al. 2017; Tibpromma et al. 2017; Zhu et al. 2018). In this study, a novel species of Cytospora is introduced from Ulmus pumila L. based on molecular data coupled with morphological characteristics (Fig. 76). Cytospora ulmicola Norphanphoun, Bulgakov, T.C. Wen & K.D. Hyde, sp. nov. Index Fungorum number: IF555487; Facesoffungi number: FoF05184, Fig. 77 Etymology: The specific epithet ‘‘ulmicola’’ refers to the host plant genus Ulmus, on which the fungus was first collected. Holotype: MFLU 17-2080 Associated with twigs and branches of Ulmus pumila L. (Ulmaceae). Sexual morph Undetermined. Asexual morph Conidiostromata 1000–1700 9 500–800 lm diam., semi-immersed in host tissue, solitary, erumpent, scattered, discoid, circular to ovoid, with multi-loculate, pycnidial, embedded in stromatic tissue, with ostiole. Ostioles 200–500 lm long, with an ostiolar neck. Conidiomata walls comprising a few layers of pseudoparenchymatous cells of textura angularis, with inner layer thin, pale brown, outer layer brown to dark brown. Conidiophores unbranched or occasionally branched at the base, formed from the inner layer of the pycnidial wall. Conidiogenous cells (6–)9– 14 9 1.3–1.8(–2.8) lm ( x = 11 9 2 lm, n = 15), blastic, enteroblastic, flask-shaped, phialidic, hyaline, and smoothwalled. Conidia (7–)8–9.5 9 1.5–1.7(–1.9) lm ( x = 8.5 9 1.6 lm, n = 30), unicellular, hyaline, oblong to allantoid, smooth-walled. Culture characteristics: Conidia germinating on PDA within 12 h. Germ tubes produced from all sides. Colonies on PDA reaching 22–27 mm diam. after 2 weeks at room temperature, colonies irregular in shape, medium dense, flat to slightly raised, surface slightly rough, with small 123 Fungal Diversity Fig. 74 Maximum likelihood (ML) majority rule consensus tree for the combined LSU, SSU and ITS sequence alignment for Atractosporales.

Material examined: RUSSIA, Rostov region, Shakhty City, street trees, on dead branch of Ulmus pumila L. (Ulmaceae), 27 May 2017, T.S. Bulgakov, T-1778 (MFLU 17-2080, holotype; PDD, isotype), ex-type living culture, MFLUCC 18-1227. GenBank numbers: ACT = MH940216, ITS = MH940220, LSU = MH940218, TUB2 = MH986792. Notes: Cytospora ulmicola (MFLU 17-2080) was found on a dead branch (with signs of necrosis) of Ulmus pumila in European Russia. Cytospora ulmicola resembles Cytospora species in having an ostiolar neck with multi-loculate conidiostromata and unicellular, oblong to allantoid conidia. Phylogenetic analysis based on a combined ITS, LSU and ACT sequence dataset indicates that C. ulmicola clusters with C. cotini Norph. et al. (MFLUCC 14-1050), C. ampulliformis Norph. et al. (MFLUCC 16-0583), C. gelida Norph. et al. (MFLUCC 16-0634), and C. ceratosperma (Tode) G.C. Adams & Rossman (MFLUCC 16-0625) (Fig. 76). However, C. ulmicola can be distinguished from related species based on molecular data. A comparison of nucleotide polymorphisms of ITS and ACT shows that C. ulmicola differs from C. cotini with one polymorphism of ITS; from C. ampulliformis with one polymorphism of ITS and ten polymorphisms of ACT; from C. gelida with four polymorphisms of ITS and 13 polymorphisms of ACT; and from C. ceratosperma with five polymorphisms of ITS and eight polymorphisms of ACT. Therefore, following the guidelines of Jeewon and Hyde (2016) we introduce it as a new species. Melanconiellaceae Senan. et al. Melanconiellaceae was introduced by Senanayake et al. (2017) including phytopathogenic and saprobic species to accommodate Greeneria Scribn. & Viala, Melanconiella Sacc. and Microascospora Senan. & K.D. Hyde in the order Diaporthales (Senanayake et al. 2018; Braun et al. 2018). We introduce a new monotypic genus Septomelanconiella to the family Melanconiellaceae to accommodate a single species collected on rose apple in Thailand. Septomelanconiella Samarak. & K.D. Hyde, gen. nov. Index Fungorum number: IF555301; Facesoffungi number: FoF04849 Etymology: The generic epithet ‘‘Septomelanconiella’’ reflects the septation of the conidia and parallel morphology to Melanconiella. Saprobic on Syzygium samarangense in terrestrial habitats. Sexual morph Undetermined. Asexual morph 123 Fig. 76 Phylogram generated from maximum likelihood analysis c based on a combined ITS, LSU, and ACT sequence dataset. The tree is rooted to Diaporthe eres (AFTOL-ID 935). Maximum likelihood bootstrap values C 50% are given at the nodes. Newly generated sequence is indicated in blue. Ex-type strains are indicated in bold Coelomycetous. Conidiomata pycnidial, immersed in the host, partially erumpent at maturity, mostly solitary or confluent, subglobose to irregular, to flattened and collabent, light brown. Conidiomata walls comprising 2–3 layers of hyaline cells, of textura angularis at the base, with light brown, thin outer layer. Conidiophores mostly reduced to conidiogenous cells, few with conidiophore and cylindrical conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, integrated to discrete, cylindrical, determinate, hyaline, and finely roughened. Conidia cylindrical to clavate, one guttulate, becoming two guttules, hyaline, 1-septate when immature; mature conidia cylindrical to clavate, straight or slightly curved, brown, 1-euseptate, more often with 6 unequal lumina, guttulate, dark brown at the base. Type species: Septomelanconiella thailandica Samarak. & K.D. Hyde Notes: Septomelanconiella thailandica constitutes an independent lineage basal to Melanconiella syzygii Crous & M.J. Wingf. Despite average phylogenetic support, Septomelanconiella is distinguished from other species as it is characterised by 1-euseptate and luminate conidia. Septomelanconiella is similar to Melanconiella in having finely verrucose, brown, mature conidia. Septomelanconiella thailandica can be phylogenetically distingushed from the other genera in Melanconiellaceae as circumscribed by Senanayake et al. (2017). Melanconiella syzygii was isolated from a prominent leaf spot of Syzygium and is characterized by 2–3 layers of peridium, 1–2-septate conidiophores and hyaline to light brown aseptate conidia (Crous et al. 2016a). Multigene phylogenetic analyses also reveal that Septomelanconiella thailandica is separated from Melanconiella syzygii. Wijayawardene et al. (2016) described Gloeocoryneum and Stegonosperiopsis and referred them to Ascomycota, genera incertae sedis. They have similar brown, septate conidia as in Septomelanconiella thailandica. However, Gloeocoryneum differs in having 2–5 conidial septa, while Stegonosperiopsis is characterized by cylindrical conidiophores. Based on morphology and phylogeny in this study, Septomelanconiella thailandica is introduced as a new genus and species (Figs. 78, 79). Septomelanconiella thailandica Samarak. & K.D. Hyde, sp. nov.

Holotype: MFLU 18-0793 Saprobic on recently dead twigs of Syzygium samarangense. Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata 360–500 lm diam., 130– 200 lm high, pycnidial, immersed, partially erumpent at maturity, solitary or confluent, subglobose to irregular, to flattened and collabent, light brown. Conidiomata walls 28–37.5 lm wide, comprising 2–3 layers of hyaline cells, of textura angularis at the base, with light brown, thin outer layer.

( x = 2.9 lm, n = 30). Culture characteristics: Conidia germinating on PDA within 24 h, germ tubes produced from central part, often three hyphae. Colonies on PDA reaching 37 mm diam. in 2 weeks at 25 °C, hairy, white, superficial, rough surface, irregular edge, reverse yellowish brown. Material examined: THAILAND, Chiang Rai Province, Muang District, Nang Lae, on dead twigs of Syzygium samarangense (Blume) Merr. & L.M. Perry (Myrtaceae), 25 January 2018, M.C. Samarakoon, SAMC091 (MFLU 18-0793, holotype; KUN-HKAS 102320, isotype), ex-type living culture, MFLUCC 18-0518, ICMP. GenBank numbers: ITS = MH727706, LSU = MH727705, RPB2 = MH752072. Pseudoplagiostomataceae Cheew. et al. The monotypic family Pseudoplagiostomataceae was introduced by Cheewangkoon et al. (2010) to accommodate a cryptosporiopsis-like fungus isolated from Eucalyptus. Pseudoplagiostomataceae resembles Gnomoniaceae G. Winter based on morphological characters of its sexual morph, such as solitary, immersed, lacking stromatic ascomata with lateral beaks, asci with a distinct apical ring and 1-septate ascospores (Sogonov et al. 2008; Senanayake et al. 2017). Cheewangkoon et al. (2010) showed phylogenetically that Pseudoplagiostomataceae is closer to families with well-developed stromatic tissue such as Diaporthaceae Höhn. ex Wehm. and Pseudovalsaceae M.E. Barr, or families with stromatic and non-stromatic tissues such as Valsaceae Tul. & C. Tul. and Sydowiellaceae Lar.N. Vassiljeva. However, in our phylogenetic analyses it forms a fullysupported lineage, sister to Apoharknessiaceae Senan. et al. (Fig. 80). Pseudoplagiostoma Cheew. et al. We follow the latest treatment and updated accounts of Pseudoplagiostoma in Cheewangkoon et al. (2010), Suwannarach et al. (2016) and Du et al. (2017). Based on phylogenetic analyses of a combined ITS, LSU, TUB2 and TEF1-a dataset coupled with morphological characteristics, a novel species, P. mangiferae is introduced. Pseudoplagiostoma mangiferae Dayarathne, Phookamsak & K.D. Hyde, sp. nov. Index Fungorum number: IF555434; Facesoffungi number: FoF05111, Fig. 81 Etymology: The specific epithet ‘‘mangiferae’’ refers to the host genus Mangifera, of which the species was first collected. Holotype: KUN-HKAS 102244 Associated with the leaf blight symptom on Mangifera sp. having amphigenous, subcircular to irregular, medium brown with blackish brown, reverse medium brown, surrounded by a purple-brown margin, which is dark brown in reverse. Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata 70–140 lm high, 90– 150 lm diam. ( x = 109 9 125 lm, n = 10), medium to dark brown, pycnidial with pale yellow drops of exuding conidia; subglobose, subcuticular to epidermal, with central rupture, breaking through plant tissue. Conidiomata walls 5–10 lm wide, thin-walled, composed of 2–4 layers of yellowish brown, pseudoparenchymatous cells, of textura angularis, intermixed with the host cells at the base and side. Paraphyses 0.8–2 lm wide, branched, septate, hyaline. Conidiophores absent. Conidiogenous cells 5– 11 9 3.2–12.6 lm ( x = 9 9 6 lm, n = 30), proliferating enteroblastic, appearing as phialides with periclinal thickening and collarette, or with percurrent proliferation in the apical part; discrete, arising from the inner cell layer, hyaline, smooth, cylindrical to ampulliform, wider at the base, straight. Conidia 18–24 9 11–14 lm ( x = 22 9 13 lm, n = 50), hyaline, ellipsoidal, guttulate, smooth, thick-walled, aseptate, straight or slightly curved, frequently slightly narrow at the middle, with obtuse apex; base tapering to flat protruding scar. Culture characteristics: Colonies on PDA reaching 80–85 mm diam. after 4 weeks at 20–25 °C, sparse to medium sparse, circular, flat, surface slightly rough with tufts of hyphae, edge entire, woolly to cottony, radiating with sparse mycelia in the middle part; from above, pinkwhite to cream, from below, pale yellowish; not producing pigmentation in agar. Material examined: CHINA, Yunnan Province, Xishuangbanna, Jinghong, Nabanhe, associated with leaf blight symtom on living leaf of Mangifera sp. (Anacardiaceae), 21 November 2015, R. Phookamsak, XB010 (KUN-HKAS 102244, holotype), ex-type living culture, KUMCC 18-0179. GenBank numbers: ITS = MK084824, LSU = MK084825, TEF1-a = MK084822, TUB2 = MK084823. Notes: Morphological characteristics clearly distinguish Pseudoplagiostoma mangiferae from other Pseudoplagiostoma species. The conidiogenous cells of P. mangiferae (5–11 9 3.2–12.6 lm) are wider than those of P. eucalypti (6–15 9 2–6 lm) (Cheewangkoon et al. 2010). Pseudoplagiostoma variabile is distinguished from P. mangiferae by its subglobose to bean-shaped, variable conidia shape (Cheewangkoon et al. 2010). The conidia of P. corymbiae (14–19 9 7–10 lm), P. eucalypti (14–22 9 6–11 lm), P. oldie (11–20 9 6–11 lm) and P. variabile (6.5–19 9 6.5–10.5 lm) are shorter than those of P. mangiferae (18.8–24 9 11.3–14.2 lm) while P. dipterocarpi (14–36 9 7–11 lm) has longer conidia 123 Fungal Diversity Fig. 78 Phylogram generated from maximum likelihood (RAxML) based on ITS, LSU and RPB2 partial sequence data analyses of 23 taxa and Pseudoplagiostoma oldii (CBS 124808) as an outgroup taxon. Bootstrap values for maximum parsimony (green) and maximum likelihood (blue) C 50% and Bayesian posterior probabilities (black) C 0.90 are given at the nodes. The newly generated sequence is in blue. The ex-type strains are in bold. The scale bar represents the expected number of nucleotide substitutions per site (Cheewangkoon et al. 2010; Crous et al. 2012; Suwannarach et al. 2016). Furthermore, P. oldie is distinguished from P. dipterocarpi by its conidia turning brown when mature (Cheewangkoon et al. 2010). According to our multigene analyses, P. mangiferae shows a close phylogenetic relationship with P. dipterocarpi (Fig. 80). However, they form well-separated lineages with high support (94% ML, 98% MP and 0.97 BYPP). A comparison of ITS nucleotide bases shows that P. mangiferae differs from P. dipterocarpi in 67/512 bp (13.1%). We therefore, introduce P. mangiferae as a new species following the guidelines of Jeewon and Hyde (2016). The genus Coniella was introduced by von Höhnel (1918) and is typified by Coniella pulchella Höhn. (= C. fragariae (Oudem.) B. Sutton). This genus comprises endophytes, saprobes and plant pathogens (Van Niekerk et al. 2004; Alvarez et al. 2016; Chethana et al. 2017). A new host record collected on Prunus armeniaca L. from Russia is reported for C. vitis, which has been previously reported as a plant pathogen from Vitis vinifera L. (Vitaceae; Chethana et al. 2017) (Fig. 82). Schizoparmaceae Rossman Schizoparmaceae was introduced by Rossman et al. (2007) and is typified by Schizoparme Shear. The family also includes Pilidiella Petr. & Syd., the asexual morph of Schizoparme and the closely related Coniella Höhn (Rossman et al. 2007). In a recent revision, these three genera were synonymized under the old name, Coniella (Alvarez et al. 2016). Coniella Höhn. 123 Coniella vitis Chethana, J.Y. Yan, X.H. Li & K.D. Hyde, Pl.

Diaporthomycetidae, families incertae sedis Distoseptisporaceae K.D. Hyde & McKenzie Distoseptisporaceae was introduced by Su et al. (2016) and classified in Diaporthomycetidae, families incertae sedis by Wijayawardene et al. (2018a). The family consists of one hyphomycetous genus, Distoseptispora which is typified by D. fluminicola McKenzie et al. Seventeen Distoseptispora species have been introduced through previous studies, out of which eleven species are from freshwater, and five species are from terrestrial habitats (Hyde et al. 2016; Su et al. 2016; Xia et al. 2017; Luo et al. 2018; Tibpromma et al. 2018; Yang et al. 2018c) (Fig. 84).

Material examined: CHINA, Yunnan Province, Xishuangbanna, Mengla County, Xishuangbanna Tropical Botanical Garden (XTBG), on dead culms of Thysanolaena maxima (Roxb.) Kuntze (Poaceae), 22 April 2017, R. Phookamsak, IS004 (KUN-HKAS 102247, holotype), extype living culture, KUMCC 18-0182 (IS004A), KUMCC 18-0183 (IS004B). GenBank numbers: ITS = MK045851, LSU = MK064091, TEF1-a = MK086031. Notes: Distoseptispora thysanolaenae is the sixth species in this genus to be introduced from a terrestrial habitat. The previously introduced species are D. martini (J.L. Crane & Dumont) J.W. Xia & X.G. Zhang, D. tectonae Doilom & K.D. Hyde, D. tectonigena Doilom & K.D. Hyde, D. thailandica Tibpromma & K.D. Hyde and D. xishuangbannaensis Tibpromma & K.D. Hyde (Hyde et al. 2016; Xia et al. 2017; Luo et al. 2018; Tibpromma et al. 2018). Distoseptispora thysanolaenae can be distinguished from these species by its 2–8-septate conidiophore that are 30–80 9 3.5–5.5 lm and narrow elongated, obclavate, light to dark brown conidia that are 21.5–80 9 6.5–12.8 lm, 8–14-distoseptate and smooth-walled. Distoseptispora martini has longer conidiophores (50–110 9 3.5–4.5 lm), shorter and wider conidia (15–20 9 11–16 lm) that are ellipsoid, oblate or subglobose (Xia et al. 2017). Distoseptispora tectonae and D. tectonigena differ in their conidiophore dimensions (up to 40 9 4–6 lm, and up to 110 9 5–11 lm, respectively) and conidial dimensions Fungal Diversity 123 Fungal Diversity Fig. 83 Coniella vitis (MFLUCC 18-0093). a Host surface from which the saprobe was isolated. b Immature white pycnidia on PDA. c Mature black pycnidia with hyaline spore mass on PDA. d Conidiogenous cells. e Periclinal thickening at the apex of the conidiogenous cells. f–i Different shapes of conidia. j Upper-view (right) and the reverse view (left) of the colony on PDA. Scale bars a = 2 mm, c = 500 lm, d, e = 10 lm, f–i = 5 lm ((90–)130–140(–170) 9 13–14 lm, and 148–225(–360) 9 11–12 lm, respectively) and number of septa. Distoseptispora thailandica and D. xishuangbannaensis have larger conidia (130–230 9 13.5–17 lm and 160–305 9 8–15 lm, respectively) and more septa (35–52-distoseptate, and up to 40-distoseptate, respectively) (Tibpromma et al. 2018). Phylogenetic analyses based on a combined ITS, LSU and TEF1-a sequence dataset show that our taxon clusters with other Distoseptispora species (Fig. 84). The species is sister to D. guttulata J. Yang & K.D. Hyde (MFLUCC 16-0183). A comparison of ITS and TEF1-a nucleotide bases shows that D. thysanolaenae differs from D. guttulata with 59 nucleotide bases of ITS and 64 nucleotide bases of TEF1-a. Distoseptispora thysanolaenae shares similar morphological features with D. guttulata but can be distinguished from the latter in having shorter conidia (21.5–80 lm versus 75–130 lm; Yang et al. 2018c). Therefore, following the guidelines of Jeewon and Hyde (2016) we introduce it as a new species. Diaporthomycetidae, genera incertae sedis 123 Proliferophorum G.N. Wang, H. Zhang, K.D. Hyde & Senan., gen. nov. Index Fungorum number: IF555401; Facesoffungi number: FoF04847 Etymology: The generic epithet ‘‘Proliferophorum’’ refers to the proliferation of conidiophores. Saprobic on decaying, submerged wood in freshwater habitat. Sexual morph Undetermined. Asexual morph Hyphomycetous. Colonies irregular, hairy, black, gregarious. Mycelium mostly immersed in substratum, consisting of branched, septate, subhyaline to pale brown, smooth hyphae. Conidiophores macronematous, mononematous, caespitose, cylindrical, unbranched, erect, straight and curved at the upper part, dark brown, light brown at the apex, 8–10-septate, not constricted at the septa, smooth, sometimes percurrently proliferating 1–2 times at broken ends, with few upper cells, guttulate. Conidiogenous cells holoblastic, polyblastic, terminal, sympodial, pale brown or subhyaline, with minute, truncate conidiogenous loci. Fungal Diversity Fig. 84 Phylogenetic tree generated by maximum likelihood analysis of a combined ITS, LSU and TEF1-a sequence dataset of Distoseptisporaceae and other related families in Diaporthomycetidae. Related sequences were obtained from GenBank. Fifty one strains are included in the analyses, which comprised 2409 characters including gaps. Single gene analyses were carried out and compared with each species, to compare the topology of the tree and clade stability. The tree is rooted with Sordaria fimicola (SMH 4106, FGSC 2918). Tree topology of the ML analysis was similar to the MP and BI. The best scoring RAxML tree with a final likelihood value of -17019.410141 is presented. The matrix had 1186 distinct alignment patterns, with 38.62% of undetermined characters or gaps. Estimated base frequencies were as follows: A = 0.237054, C = 0.262859, G = 0.290202, T = 0.209884; substitution rates AC = 1.172995, AG = 2.180726, AT = 1.594744, CG = 1.095103, CT = 6.416481, GT = 1.000000; gamma distribution shape parameter a = 0.352856. The maximum parsimonious dataset consisted of 1183 constant characters, 751 parsimony-informative and 475 parsimony-uninformative characters. The parsimony analysis of the data matrix resulted in the maximum of two equally most parsimonious trees with a length of 2985 steps (CI = 0.590, RI = 0.726, RC = 0.428, HI = 0.410) in the first tree. RAxML (black) and maximum parsimony (blue) bootstrap support values C 60% are shown respectively above the nodes. Bayesian posterior probabilities C 0.95 BYPP indicated in green. The scale bar indicates 0.1 changes. The ex-type strains are in bold and a new isolate is in blue Conidia fusiform to cylindrical, aseptate when young, 2–3septate when mature, rarely up to 4-septate, slightly constricted at the septa, dark brown at central cells, pale brown at end cells, guttulate at some stage, dry, smooth. Type species: Proliferophorum thailandicum G.N. Wang, H. Zhang, K.D. Hyde & Senan. Notes: Proliferophorum is introduced as a monotypic genus in the subclass Diaporthomycetidae to accommodate a hyphomycetous species forming mononematous, caespitose conidiophores, sometimes percurrently proliferating 1–2 times at broken ends of conidiogenous cells and fusiform to cylindrical conidia. The genus was found on wood, 123 Fungal Diversity 123 Fungal Diversity b Fig. 85 Distoseptispora thysanolaenae (KUN-HKAS 102247, holo- type). On host substrate: a Appearance of colonies on host surface. b, d, e Conidiophores. c, f Conidiophores with attached conidia. g– i Variable shapes of conidia.

Scale bars a = 500 lm, b–i, k–r = 20 lm, s = 50 lm similar to the genus Minimelanolocus R.F. Castañeda & Heredia, which has conidiophores that are generally conspicuous, mononematous, solitary or fasciculate, septate, erect, straight or flexuous, smooth or verrucose, and brown to dark brown with a melanised base (Castañeda-Ruiz et al. 2003). The conidia of Minimelanolocus are generally, cylindrical, naviculate, clavate, obclavate and pale brown to dark brown (Liu et al. 2015b). However, Proliferophorum differs from Minimelanolocus in its conidiophores that have a few upper guttulate cells and conidia having obvious droplets. In addition, LSU sequence data analysis shows the genus does not group with species in Chaetothyriales. Phylogenetic analyses (Fig. 86) of taxa within Diaporthomycetidae indicate that Proliferophorum forms a single lineage, between Phomatosporales Senan. et al. and Amplistromatales M.J. D’souza et al. The sporothrix-like asexual morph of Phomatosporales was reported from culture by Rappaz (1992). Amplistromatales comprises the families Amplistromataceae Huhndorf et al. and Catabotrydaceae Petr. ex M.E. Barr and their asexual morphs have been reported as acrodontium-like for Amplistroma Huhndorf et al. (Maharachchikumbura et al. 2015). Proliferophorum and acrodontium-like asexual morphs are distinct. Proliferophorum thailandicum G.N. Wang, H. Zhang, K.D. Hyde & Senan., sp. nov.

Plectosphaerellaceae was introduced by Zare et al. (2007) to accommodate the genera Acrostalagmus Corda, Gibellulopsis Bat. & Maia, Musicillium Zare & W. Gams, Plectosphaerella and Verticillium Nees, with Plectosphaerella as the type genus and P. cucumeris Kleb. being the type species. Eleven genera are accepted in this family viz.

Newly introduced strain is in blue bold and type strains are in bold. The tree is rooted to Leotia lubrica (AFTOLID 1 = OSC 100001). The combined LSU, SSU and ITS sequence dataset comprised 67 strains (including the new strain and outgroup taxon) and manually adjusted dataset totally comprised 2228 characters including gaps. The best scoring RAxML tree was selected to represent the relationships among taxa, in which a final likelihood value of - 22073.200898 Etymology: The specific epithet ‘‘kunmingensis’’ refers to Kunming City, Yunnan, China where the species was first collected. Holotype: KUN-HKAS 102246 Colonies forming on PDA. Mycelium composed of 1– 3 lm wide, septate, branched, smooth and thin-walled, hyaline hyphae, partly immersed on PDA. Sexual morph forming black, obpyriform ascomata after 8 weeks at 20– 25 °C. Ascomata 100–185 lm high, 80–110 lm diam., perithecial, superficial or immersed in culture colonies, scattered, solitary to gregarious, subglobose to ovoid, or obpyriform, uni-loculate, glabrous, ostiole at centre, with a minute papilla. Peridium 7–18 lm wide, thin-walled, of equal thickness, composed of 1–3 layers, of dark brown pseudoparenchymatous cells, arranged in a textura angularis. Asci (42–)45–55(–62) 9 10–13 lm ( x = 51.9 9 11.6 lm, n = 15), 8-spored, unitunicate, cylindric-obclavate to obpyriform, subsessile, thick-walled at apex, with J-, subapical ring. Ascospores (8–)10–13(–15) 9 3–5 lm ( x = 11.9 9 4.3 lm, n = 50), overlapping 1–2-seriate, hyaline, ellipsoidal to subfusoid, with round ends, 1-septate, smooth-walled with small guttules, becoming finely echinulate when stained by Melzer’s reagent. Asexual morph Hyphomycetous, Conidiophores 15–50(–58) 9 (1.5–)3– 5 lm ( x = 38.5 9 4.2 lm, n = 20), macronematous or micronematous, produced from prostrate hyphae, lacking hyphal coils, sometimes branched, hyaline, yellowish brown at the base, thick-walled, smooth, septate, branched, straight or flexuous. Conidiogenous cells phialidic, determinate, integrated to discrete, hyaline, subcylindrical to ampulliform, smooth-walled, with periclinal wall thickening, with minute collarette. Conidia 7–10 9 4–7 lm ( x = 8.7 9 5.4 lm, n = 50), pleurogenous or acropleurogenous, formed in slimy heads at the apex of the phialides, hyaline, subglobose to ellipsoidal, aseptate, smooth, thinwalled, with granular contents. Chlamydospores not produced. Culture characteristics: Colonies on PDA reaching 40–48 mm diam. after 3 weeks at 20–25 °C, dense, irregular in shape, flat to slightly raised, slightly rough at surface, with mycelia radiating outwards, sometimes forming sectors of different folds, fimbriate at edge, mucoid to floccose; from above, white yellowish to cream; from below, pale yellowish; not producing pigmentation in agar medium. Material examined: CHINA, Yunnan Province, Kunming City, Kunming Institute of Botany, colonies forming on WA as a contaminated fungus, 5 July 2017, R. Phookamsak, KIB042 (dried culture herbarium: KUNHKAS 102246, holotype), ex-type living culture, KUMCC 18-0181. GenBank numbers: ITS = MH254296, LSU = MH254298, RPB2 = MH254297, TEF1-a = MH254295. Notes: Phylogenetic analyses of a combined ITS, LSU and TEF1-a sequence dataset (Fig. 88) show the new species, Plectosphaerella kunmingensis forming a distinct lineage at the basal clade of Plectosphaerella in Plectosphaerellaceae with moderate support (76% ML and 0.96 BYPP). Plectosphaerella kunmingensis can be distinguished from other Plectosphaerella species in the lack of hyphal coils, as well as having partly coloured conidiophores. The sexual morph of P. kunmingensis differs from P. cucumerina in having smaller asci (P. kunmingensis, (42–)45–55(–62) 9 10–13 lm versus 50–80 9 6–9 lm, P. cucumerina; Carlucci et al. 2012) and wider ascospores (P. kunmingensis, (8–)10–13(–15) 9 3–5 lm versus (9–)10.5–14(–15) 9 2.5–3(–4) lm, P. cucumerina; Carlucci et al. 2012) (Fig. 90). Another species, Plectosphaerella sinensis was also found from China isolated from a healthy stem of Cucumis melo L. (Cucurbitaceae) (Su et al. 2017). Whereas, our isolate was found as a contaminated fungus on WA. Plectosphaerella kunmingensis has subglobose to ellipsoidal, aseptate conidia and lacks chlamydospores, while P. sinensis has ellipsoidal, 0–1-septate conidia with a slightly apiculate base, and forming intercalary or terminal, irregular, thick-walled chlamydospores (Su et al. 2017). In the BLASTn search on NCBI GenBank, the closest matches of ITS sequence of P. kunmingensis are P. nepalense (CBS 971.72) and P. cucumerina (XSD-75) with 95% similarities for both strains. In addition, a comparison of ITS nucleotide bases between P. kunmingensis and P. niemeijerarum (CBS 143233) shows that they differ in 42 base positions (8.08%/520 bp). Based on a molecular analyses coupled with morphological characteristics, we therefore, propose P. kunmingensis as a new species. Hypocreales Lindau Cordycipitaceae Kreisel ex G.H. Sung et al. Cordycipitaceae was validated by Sung et al. (2007) to accommodate the type of Cordyceps Fr., C. militaris (L.) Fr. and most of Cordyceps species forming brightly coloured, fleshy stromata.

Eighteen genera are listed in this family (Wijayawardene et al. 2018a). We follow the latest treatment and updated accounts of Cordycipitaceae in Kepler et al. (2017). Leptobacillium Zare & W. Gams The genus Leptobacillium was introduced by Zare and Gams (2016) to accommodate saprotrophic and fungicolous phialidic hyphomycetes and Leptobacillium leptobactrum (W. Gams) Zare & W. Gams is the type species. We follow the latest treatment in Zare and Gams (2016). Leptobacillium leptobactrum var. calidius is reported for the first time in India. Leptobacillium leptobactrum var. calidius Zare & W. Gams, Mycol Progr 15: 1003 (2016) Facesoffungi number: FoF04832, Fig. 91 Holotype: GHANA, Atewa. CBS H-22406, a dried culture of CBS 748.73 (= IHEM 3708), from living lepidopteran larva collected by H.C. Evans. Colour codes follow: Methuen Handbook of Colour (Kornerup and Wanscher 1978) Saprobic on phylloplane. Sexual morph Undetermined. Asexual morph Conidiophores 36–173.5 9 1.2–2.8 lm ( x = 97 9 1.5 lm, n = 30), cylindrical, mainly solitary or in groups (2–3), simple to branched, smooth-walled, hyaline. Conidiogenous cells 3.5–66.5 9 0.8–2 lm ( x = 29.5 9 1.4 lm, n = 30), phialidic, cylindrical, septate, slightly tapering towards apex, 1–3 arising from single node of condiophores. Conidia 2.5–6.2 9 0.8–1.8 lm ( x = 4 9 1.2 lm, n = 30), produced in long chains (about 20 in a chain) and in gloeosporic masses, cylindrical, bacilliform, fusiform, smooth-walled, aseptate, hyaline. Chlamydospores absent. Culture characteristics: Colonies on PDA reaching 15–28 mm diam. in 10 days, at 25 °C, white (4A1), margin smooth, entire, flat to slightly raised, puffy, sometimes produces exudates. Reverse yellowish white (4A2) to crème (4A3), wrinkled. Known hosts and distribution: Hemileia vastatrix Berk. & Broome on Coffee (Brazil), technical equipment (France, Netherlands), living lepidopteran larva (Ghana), decaying wood (Poland), cyst of Heterodera glycines Ichinohe (USA) (Zare and Gams 2016). Material examined: INDIA, Maharashtra, Pune, on phylloplane of Colocasia esculenta (L.) Schott (Araceae), 10 November 2017, S.K. Singh, living culture, NFCCI 4235, voucher specimen, AMH 10000. GenBank numbers: ITS = MG786580, LSU = MG786581. Notes: Phylogenetic analysis based on a combined ITS and LSU sequence dataset of 24 taxa shows that the Indian taxon (NFCCI 4235) clusters with type of Leptobacillium leptobactrum var. calidius Zare & W. Gams (CBS 748.73) (Fig. 90). Mega blast search of ITS sequence shows 99% similarity (505/508) with L. leptobactrum var. calidius (CBS 748.73) and same similarity (99% similarity, 592/594) for LSU analysis. In this isolate conidia are produced in long chains and in gloeosporic masses. Though slight variations in conidial length and width were observed, our isolate is similar to L. leptobactrum var. calidius (CBS 748.73) in overall morphological characteristics. In addition, our isolate optimally grows at 25–26 °C, the same as reported for L. leptobactrum var. calidius (CBS 748.73) with negligible growth at 30 °C. Optimum temperature for growth of L. leptobactrum var. leptobactrum is 18–21 °C (Zare and Gams 2016). Leptobacillium leptobactrum var. calidius and L. leptobactrum var. leptobactrum were treated as a synonym of L. leptobactrum (Index Fungorum 2019). However, L. leptobactrum var. calidius (CBS 748.73) forms a distinct lineage with the type strain of L. leptobactrum (CBS 771.69). Hence, based on similarity in morphological characteristics, temperature requirements, and phylogenetic analysis this Indian isolate is identified as L. leptobactrum var. calidius (Zare and Gams 2016). To our knowledge, this is the first report of this genus, species and variety isolated from phylloplane of a different host, Colocasia esculenta from India. Hypocreaceae De Not. Hypocreaceae was introduced by De Notaris (1844) and is typified by Hypocrea Fr. Species of Hypocreaceae are characterized by their brightly coloured, fleshy perithecial stromata (Rogerson 1970). The family comprises 18 genera and more than 450 species (Kirk et al. 2008; Wijayawardene et al. 2018a). Trichoderma Pers. Trichoderma is frequently isolated from various habitats including soil, decaying wood, and vegetable matter (Samuels 2006) and is known to play an important ecological role as biocontrol agents of plant diseases, producers of bioactive compounds, and pathogens of animals and mushrooms (Schuster and Schmoll 2010). Based on molecular data, more than 250 species are currently accepted in this genus (Bissett et al. 2015). Three novel species are introduced based upon their phylogenetic affinities clarified by maximum likelihood and Bayesian inference analyses of a combined TEF1-a and RPB2 sequence dataset (Fig. 92). 123 Fungal Diversity Fig. 88 Phylogenetic tree generated from maximum likelihood analysis based on a combined LSU, ITS and TEF1-a sequence dataset of the genera in Plectosphaerellaceae.

Morphologically and phylogenetically, T. rugulosum is closely related to species in the T. harzianum complex. However, these species have faster growth at 30 °C on SNA (32–70 mm on SNA after 3 days). T. rugulosum shows a wrinkle in colony reverse on PDA at 25 °C and wavy margin on PDA at 30 °C, features not seen in members of the T. harzianum complex. Hypocreales, genera incertae sedis Emericellopsis Beyma Emericellopsis Beyma (1940) was introduced with E. terricola Beyma as the type species. Emericellopsis species have been mostly isolated as saprobes from marine environments, soda lakes, and terrestrial habitats (GrumGrzhimaylo et al. 2013). We describe a novel species from Korea based on phylogenetic analysis of a combined ITS and TUB2 sequence dataset (Fig. 96). Emericellopsis koreana Hyang B. Lee, S.J. Jeon & T.T.T. Nguyen, sp. nov.

Culture characteristics: The isolate grows over a wide range of temperatures with varying growth rates. The average growth rates of CNUFC-MOG1-1 on MEA, CYA, and PDA medium at 25 °C were 27.5, 17, and 15.5 mm after 7 days, respectively. Optimal growth was observed around 25 °C, slow growth was observed below 10 °C, and no growth at 40 °C. Material examined: REPUBLIC OF KOREA, Jeonnam Province, garden of the Chonnam National University located in Gwangju (35°10’20.2’’N 126°530 57.200 E), from gut of a mosquito larva, 15 September 2016, H.B. Lee, CNUFC-MOG1-1 (holotype), ex-type living culture, JMRC:SF:013604. GenBank numbers: ITS = MH173304, TUB2 = MH243035 (CNUFC-MOG1-1); ITS = MH173305, TUB2 = MH243036 (CNUFC-MOG1-2). Notes: Emericellopsis koreana, which forms a subclade with E. donezkii Beliakova, E. humicola (Cain) Cain ex Grosklags & Swift, E. persica Papizadeh et al. and Emericellopsis sp., differs by having smaller conidia. In the phylogenetic tree based on a combined ITS and TUB2 sequence dataset (Fig. 96), the strains CNUFC-MOG1-1 and CNUFC-MOG1-2 form a separate branch from other related species of Emericellopsis and is considered to be a new species. Subclass Savoryellomycetidae Hongsanan et al. Savoryellales Boonyuen et al. Savoryellaceae Jaklitsch & Réblová Savoryellaceae was introduced by Jaklitsch (2015) and is typified by Savoryella E.B.G. Jones & R.A. Eaton. The family is characterized by immersed to superficial, globose to pyriform, coriaceous, papillate ascomata, clavate to cylindrical, unitunicate asci, with an inamyloid apical ring, paraphyses, ellipsoidal to fusiform, versicolorous, septate ascospores, with or without polar mucilaginous pads or appendages and dematiaceous, hyphomycetous asexual morphs (Jaklitsch 2015). Most species of Savoryellaceae are aquatic occurring on submerged wood in freshwater, marine and brackish habitats worldwide (Jaklitsch 2015; Xia et al. 2017). The generic type, Savoryella was re-circumscribed by Maharachchikumbura et al. (2016) and the 123 Fungal Diversity higher level classification of the families in Savoryellomycetidae was revised by Hongsanan et al. (2017) based on phylogenetic and molecular clock evidence. Six genera are accepted in this family (Wijayawardene et al. 2017a, 2018a). Canalisporium Nawawi & Kuthub. The genus Canalisporium was introduced by Nawawi and Kuthubutheen (1989) to accommodate muriform asexual morph species, with conidia that are flattened dorsiventrally, comprising a single layer of regularly arranged cells, which are supported by a small, thin-walled, cuneiform, pale basal cell. There are 12 species in this genus (Zhao et al. 2013). Five species lack molecular data, viz. C. kenyense Goh et al., C. microsporum G.Z. Zhao, C. nigrum G.Z. Zhao, C. panamense A. Ferrer & Shearer and C. variabile Goh & K.D. Hyde (Goh et al. 1998; Sri-Indrasutdhi et al. 2010; Zhao et al. 2013). In this study, Canalisporium kenyense was collected from submerged decaying wood in a freshwater stream in Thailand. The taxon is re-circumscribed and illustrated as the reference specimen (Figs. 98, 99). Canalisporium kenyense Goh, W.H. Ho & K.D.

Lu, CR01 (MFLU 17-1086, reference specimen designated here); ibid., KUN-HKAS 97477. GenBank numbers: ITS = MH701998, LSU = MH701999, TEF1-a = MH708885. 123 Known hosts and distribution: On decaying wood (Kenya), submerged wood (Hong Kong), decorticated branches of dead tree (China), decaying branches of unidentified plant (China) (Goh et al. 1998; Zhuang 2001; Zhao et al. 2013; Farr and Rossman 2018). Notes: Our new collection resembles Canalisporium kenyense in morphological characters of the conidiophores, conidiogenous cells and conidia, and their measurements align with those of the holotype (IMI 285428a) (Goh et al. 1998) and other specimens of C. kenyense (Zhao et al. 2013). Therefore, we identify our new collection as C. kenyense which is the first report from Thailand. Phylogenetically, C. kenyense forms a distinct lineage within the genus Canalisporium with strong support (96% ML and 1.00 BYPP; Fig. 98). Based on morphological characters and phylogenetic support, we designate our collection MFLU 17-1086 as a reference specimen. Subclass Sordariomycetidae O.E. Erikss. & Winka Chaetosphaeriales Huhndorf et al. Chaetosphaeriaceae Réblová et al. Chaetosphaeriaceae is a widespread, species-rich family, which was invalidly introduced by Locquin (1984) to accommodate Chaetosphaeria Tul. & C. Tul., Loramyces W. Weston, Niesslia Auersw., Rhagadostoma Körb. and Zignoëlla Sacc., (Réblová et al. 1999; Hyde et al. 2017). Réblová et al. (1999) re-described and validated Chaetosphaeriaceae and accepted Ascocodinaea Samuels et al., Chaetosphaeria, Melanochaeta E. Müll. et al., Melanopsammella Höhn., Porosphaerella E. Müll. & Samuels, Porosphaerellopsis Samuels & E. Müll. and Striatosphaeria Samuels & E. Müll. Currently, 38 genera are accepted in Chaetosphaeriaceae (Hyde et al. 2017; Tibpromma et al. 2018; Wijayawardene et al. 2018a). We introduce Thozetella lithocarpi sp. nov. from Lithocarpus sp. and record Macaranga tanarius as a new host record for Chaetosphaeria panamensis based on both morphological and phylogenetic analyses (Fig. 100). Chaetosphaeria Tul. & C. Tul. The saprobic genus, Chaetosphaeria was introduced by Tulasne and Tulasne (1863) based on the type species, C. innumera Berk. & Broome ex Tul. & C. Tul., and currently comprise 165 epithets (Index Fungorum 2019). Chaetosphaeria is placed in Chaetosphaeriaceae (Chaetosphaeriales) based on molecular data (Réblová et al. 1999; Huhndorf et al. 2004; Maharachchikumbura et al. 2015), although it was previously placed in Lasiosphaeriaceae by Barr (1990). Chaetosphaeria species have a diverse distribution having been recorded from both temperate and tropical countries (i.e. Canada, China, Europe, Hong Kong, New Zealand, Thailand) (Hyde et al. 1999, 2017; Réblová 2000; Perera et al. 2016; Wijayawardene et al. 2017a).

Notes: Chaetosphaeria panamensis was introduced by Huhndorf and Fernández (2005), and was collected from decorticated wood in Panama. In this study, C. panamensis is reported on another host, Macaranga tanarius from Taiwan. Phylogenetic analyses based on a combined LSU, ITS and TUB2 sequence dataset show that our strain (FU30910) clusters with the ex-type strain of C. panamensis (SMH 3596) and another representative strain (MFLUCC 15-1011) with high support (100% ML and 1.00 BYPP; Fig. 100). Based on morphological characters (superficial, globose ascomata with setae, cylindrical asci and filiform, slightly curved, 7-septate, hyaline ascospores) and molecular data of ITS region, our isolate is identical to the type (SMH 3596; Huhndorf and Fernández 2005) and hence, the new isolate is identified as C. panamensis.

Notes: Thozetella lithocarpi (MFLUCC 16-0194) shows a close relationship with T. pandanicola Tibpromma & K.D. Hyde, T. pinicola S.Y. Yeung et al. and T. nivea (Berk.) Kuntze (Fig. 100). However, T. lithocarpi can be 123 distinguished from T. pandanicola and T. pinicola in having larger conidia and presence of microawns (Jeewon et al. 2009; Tibpromma et al. 2018). Thozetella lithocarpi produces microawns with a straight apex, while they are undulating to geniculate in T. nivea (Barbosa et al. 2011). A comparison of nucleotides in ITS gene region shows that T. lithocarpi differs from T. pandanicola and T. pinicola by 9 nucleotides (1.9%) and T. nivea by 18 nucleotides (3.9%). Our new species is also compared with Thozetella species that lack molecular data.

Castañeda & G.R.W. Arnold (Castañeda-Ruiz and Arnold 1985). Thozetella canadensis Nag Raj produces verrucose microawns, while T. lithocarpi produces smooth-walled microawns (Nag Raj 1976).

Barbosa & Gusmão and T. tocklaiensis (Agnihothr.) Piroz. & Hodges also produces smaller conidia than those of T. lithocarpi. Thozetella ypsiloidea J.S. Monteiro et al. differs from T. lithocarpi by its Y-shaped microawns. Microawns of T. serrata have a serrated edge, while microawns have a straight apex in T. lithocarpi (Monteiro et al. 2016). 123 Coniochaetales Huhndorf et al. Coniochaetaceae Malloch & Cain Fungal Diversity Coniochaetaceae was established to accommodate two genera Coniochaeta (Sacc.) Cooke and Coniochaetidium Malloch & Cain by Malloch and Cain (1971). Species of Coniochaetaceae can be distinguished from other families in having ascospores with elongated germ slits. Cultures are frequently pink or orange and have a yeast-like appearance. They usually grow better at low temperatures. Conidia are produced in abundance as phialospores or rarely as aleuriospores (Malloch and Cain 1971; Huhndorf et al. 2004; Wanasinghe et al. 2018). We followed the latest phylogenetic analyses and the updated accounts of Coniochaeta in Nasr et al. (2018), Samarakoon et al. (2018) and Wanasinghe et al. (2018). A new species is introduced based on its morphological distinctiveness coupled with strong phylogenetic support (Fig. 103). Coniochaeta (Sacc.) Cooke We follow the latest treatment and updated accounts of Coniochaeta in Samarakoon et al. (2018) and Wanasinghe et al. (2018). Coniochaeta simbalensis S. Rana & S.K. Singh, sp. nov.

Hyphae thin- to thick-walled, simple to branched, smooth-walled, constricted near the septa, wall thickened, guttulate, anastomosis observed. Conidiophores 1.2–6.3 lm wide, starting in 2–3 days from slender, thin hyaline to thick, smooth-walled hyphae, mostly reduced to conidiogenous cells. Phialides 1.8–60 9 1–3.7 lm ( x = 14.3 9 2.2 lm, n = 30), variable, produced laterally from superficial hyphae, solitary or in groups (1–3), ventricose, base narrow, and middle swollen with elongated narrow tip (collar) tapered collula, variable in length, all curved, reduced in size to dentate structure like adelophialides to elongated branched.

Chlamydospores 5–8.6 9 3.4–6.7 lm ( x = 6.8 9 4.9 lm, n = 30), light to dark olivaceous brown, observed frequently, terminal to intercalary, solitary or in branched chains, wall thickened and darkened, constricted near the septa, variable in shape, globose, cylindrical to pyriform, sometimes produced laterally from short and long stalk of * 16–28 lm. Stalks septate, simple to branched, light to olivaceous brown, smooth-walled. Culture characteristics: Colonies on PDA reaching 39–45 mm diam. after 2 weeks at 25 °C; from above brownish grey (9D2) with margins fading to dull red (9B3), flat, sulcate, entire with smooth margin; from below, brownish grey (9E2) with outer margins fading to pale orange (6A3), sulcate.

Colonies on PCA reaching 29–34 mm diam. after 2 weeks at 25 °C; from above smoke brown (4F3); from below, silver grey (4E2) with a margin of nearly 5 mm yellowish white (4A2) in flat, glazy, margin entire and irregular. Material examined: INDIA, Himachal Pradesh, Kangra Dist, Simbal (31.9754 N’’ 76.6507 E’’), Mushroom rhizospheric soil, 8 July 2017, S. Rana, (AMH 9941, holotype), ex-type living culture, NFCCI 4236. GenBank numbers: ITS = MG825743, LSU = MG917738. Notes: Coniochaeta simbalensis differs from other Coniochaeta species based on the sequence analysis. On megablast analysis, ITS sequence of C. simbalensis shows 94.92% (468/493) similarity and 25 gaps (5%) with C. cateniformis (Perdomo et al.) Gené & Guarro (UTHSC 01-1644, type), 92.23% (487/528) similarity and 29 gaps (5%) with C. canina (Deanna A. Sutton et al.) Deanna A. Sutton et al. (UTHSC 11-2460, type), 93.37% (366/392) similarity and 5 gaps (1%) with C. hoffmannii (J.F.H. Beyma) Z.U. Khan et al. (CBS 245.38, type) and 87.36% (491/562) similarity and 42 gaps (7%) with C. acaciae Samarakoon et al. (MFLUCC 17-2298). Interestingly, the sources of isolation of these species are quite distinct. Coniochaeta cateniformis (UTHSC 01-1644) was isolated from canine bone marrow, C. canina (UTHSC 11-2460) from bone aspirate, canine breed German Shepard, C. hoffmannii (CBS 245.38) from butter (Khan et al. 2013) and C. acaciae (MFLUCC 17-2298) from dead trunk and branches of Acacia sp. (Samarakoon et al. 2018), whereas, C. simbalensis was isolated from rhizospheric soil of unidentified mushroom growing in soil. Coniochaeta simbalensis produces brownish grey (9D2) colonies with margins fading to dull red (9B3) and sulcate on PDA, whereas C. cateniformis and C. canina produces orange white and non-sulcate colonies. Similarly, C. simbalensis produces brownish grey (6F2), colonies on MEA as against orange red to yellowish red colonies produced by C. acaciae. Phialides of highly variable length were frequently observed in vitro by C. simbalensis. Conidia are highly variable in shape and size in C. simbalensis, ranging from oval to cylindrical to subglobose, non-truncate, and straight; whereas conidia are ovoidal to ellipsoidal, truncate and smaller in C. cateniformis, and ellipsoidal, straight 123 Fungal Diversity Fig. 102 Thozetella lithocarpi (MFLU 16-1068, holotype). a Dried seed of Lithocarpus sp. b, c Appearance of conidiomata on host substrate. d–f Conidiophores with conidia. g–i Microawns. j–l Conidia. m Germinating conidium.

Coniochaeta simbalensis also readily produces chlamydospores in culture, a feature absent in C. acaciae and C. prunicola Damm & Crous (Damm et al. 2010). Therefore, based on phylogenetic inference (Fig. 103), morphological and cultural distinctness C. simbalensis is proposed as a new species. T. labiosa S.W. Wong et al., which was collected from submerged wood in a small stream in Australia and Hong Kong (Wong et al. 1998). The genus is characterized by dark brown, immersed to semi-immersed, subglobose ascomata, with periphyses, papillate, thin-walled, pale brown peridium, paraphyses, 8-spored, unitunicate, cylindrical asci, with an unusual J-, lip-like, refractive apical ring, and hyaline, ellipsoidal-fusiform, aseptate ascospores, with narrow, roughed mucilaginous sheath (Wong et al. 1998). The asexual morph of this genus is unknown (Wijayawardene et al. 2017b). Based on the general morphology of the ascus apical ring observed with light microscopy and scanning, transmission electron microscopy, a new genus was established (Wong et al. 1998). Wong et al. (1998) suggested to place the genus in its own family due to a unique character of its apical ring. Wijayawardene et al. (2018a) treated the genus in Sordariomycetes, genera incertae sedis. We collected a Phyllachorales M.E. Barr Phyllachoraceae Theiss. & H. Syd. We follow the latest treatment and updated accounts of Phyllachoraceae in Dayarathne et al. (2017) and Mardones et al.

Material examined: CHINA, Yunnan Province, Pingbian, on submerged wood in a small river, 20 September 2017, W. Dong, WF-33A (MFLU 18-1191, a reference specimen is designated here; ibid., KUN-HKAS 101711), living culture, MFLUCC 18-1018 = KUMCC 18-0060. Known hosts and distribution: On submerged woods or twigs in Australia, Brazil, China, Hong Kong (Wong et al. 1998; Barbosa et al. 2013; this study). GenBank numbers: ITS = MK034865, LSU = MK034866, SSU = MK034867. Notes: Our isolate shares the size range of asci, ascospores, peridium and paraphyses with the type of Tamsiniella labiosa (see description). However, it has a slightly smaller ascomata compared to the type. Our isolate was collected from submerged wood in Yunnan, China, whereas the type specimen was collected from submerged wood in North Queensland, Australia. Based on morphological comparison and geographical distribution, we hence, designate our collection as a reference specimen of T. labiosa. In phylogenetic tree, Tamsiniella labiosa forms a distinct lineage in the order Phyllachorales M.E. Barr with moderate support (77% ML and 0.99 BYPP, Fig. 105). Phyllachorales species are distinctive as they are biotrophic on various hosts (Pearce and Hyde 1994; Dayarathne et al. 2017; Mardones et al. 2017, 2018). Phyllachorales species are characterized by deep black stromata of various shapes; pseudostroma inside the host tissue and usually beneath an epidermal clypeus; perithecia usually strongly melanized; cylindrical to clavate asci with an inconspicuous apical ring; and globose to filiform, mostly hyaline, 1-celled, rarely brown or septate ascospores (Parbery 1967; Cannon 1991; Dayarathne et al. 2017; Mardones et al. 2017, 2018). However, our collection was isolated from decaying wood submerged in freshwater, which was the same habitat as another freshwater ascomycete genus Ascovaginospora Fallah et al. in Phyllachoraceae (Wijayawardene et al. 2018a). Therefore, Tamsiniella is accommodated in Phyllachoraceae based on phylogenetic analyses. Sordariales Chadef. ex D. Hawksw. & O.E. Erikss Lasiosphaeriaceae Nannf. Lasiosphaeriaceae was established by Nannfeldt (1932), circumscribed by species with black ascomata and cylindrical asci, brown to hyaline ascospores, and typified by Lasiosphaeria Ces. & De Not. The family was re-circumscribed by Maharachchikumbura et al. (2015, 2016) and 35 genera were accepted in the family. Based on phylogeny, Lasiosphaeriaceae is sister to Chaetomiaceae with high support and this family has been shown to be paraphyletic, with many genera polyphyletic (Chang et al. 2010; Kruys et al. 2015; Maharachchikumbura et al. 2015, 2016). Wijayawardene et al. (2018a) listed 32 genera in Lasiosphaeriaceae. Zopfiella G. Winter Zopfiella was established by Winter (1884) to introduce Z. tabulata (Zopf) G. Winter and Z. curvata (Fuckel) G. Winter. Phylogenetic studies reported that the genera Zopfiella, Triangularia Boedijn, Cercophora Fuckel and Podospora Ces. are polyphyletic (Miller and Huhndorf 2005; Cai et al. 2005, 2006a, b; Chang et al. 2010; Kruys et al. 2015; Maharachchikumbura et al. 2015, 2016). A new species Z. indica, is introduced within Lasiosphaeriaceae based on evidence from morphology and DNA sequence data (Fig. 107). Zopfiella indica Devadatha, Jeewon & V.V. Sarma, sp. nov.

Material examined: INDIA, Tamil Nadu, Tiruvarur District, Muthupet mangroves (10.4°N 79.5°E), on the bark of intertidal mangrove wood, 28 November 2015, B. Devadatha, AMH-9907 (holotype), ex-type living culture, NFCCI-4217. GenBank numbers: ITS = KY863506, LSU = KY863507, SSU = MF168941, RPB2 = MF182396, TEF1-a = MF182400, TUB2 = MF406208. Notes: Multigene phylogenetic analyses indicate that Zopfiella indica shares a sister relation with Z. karachiensis (S.I. Ahmed & Asad) Guarro and Triangularia tanzaniensis R.S. Khan & J.C. Krug in a strongly supported monophyletic clade (Fig. 107). Zopfiella indica is clearly distinguished from Z. karachiensis and Triangularia tanzaniensis based on its ascospores having ovoid to ellipsoidal, rugose head cell, apical cauda attached to apical part of the terminal cell and primary appendage attached to the basal pedicel. Species belonging to Podospora are predominantly coprophilous whereas those belonging to Zopfiella predominantly thrive in soil or on plant substrata and less on dung. Given the existing taxonomic confusion vis-a-vis the genera Zopfiella and Podospora, we prefer to place Z. indica in the genus Zopfiella based on its occurrence on decaying wood, and presence of a septum in the dark cell. Recent phylogenetic analysis showed that Zopfiella is polyphyletic, interspersed with species belonging to other genera and hence is in need of revision along with other closely related genera such as Podospora and Triangularia, 123 both at the morphological and molecular level, by including a larger representation of the species belonging to these genera. Phylogenetic analyses carried out by Cai et al. (2006b) also indicated that Zopfiella does not constitute a monophyletic group. They felt that the characters of nonostiolate ascomata, and the absence of gelatinous appendages in ascospores that are considered important in delineating Zopfiella from Podospora (Guarro et al. 1991) are not reliable in understanding phylogenetic relationships (Cai et al. 2006b). This is because they found non-ostiolate Zopfiella species interspersed in different clades in the trees suggesting multiple origins of this morphological character. Also they found that the presence or absence of gelatinous appendages are phylogenetically less informative as different Zopfiella species grouped in different clades that also include many species possessing elaborate gelatinous appendages. Cai et al. (2006b) suggested that Zopfiella should be restricted to species with a septum in the dark cell. There are two strains under the name Zopfiella karachiensis (IFO32902 and CBS 657.74) in GenBank, which were included in our phylogenetic analysis. However, these two strains formed a separated lineage in our phylogenetic tree (Fig. 107). Zopfiella karachiensis (IFO32902) is sister to Z. lundqvistii (NBRC30585); whereas, Z. karachiensis (CBS 657.74) clustered with Triangularia tanzaniensis and Z. indica (our present strain). Taxonomic revision of genera in this family is needed based on multigene phylogenetic analyses. Subclass Xylariomycetidae O.E. Erikss. & Winka Amphisphaeriales D. Hawksw. & O.E. Erikss. Amphisphaeriaceae G. Winter The family Amphisphaeriaceae was introduced by Winter (1887) to accommodate Amphisphaeria and allied taxa. Amphisphaeriaceae is mainly characterized by perithecial, semi-immersed to erumpent ascomata, dark peridium, unitunicate, cylindrical asci, with J ? or J-, apical rings, pale to dark brown, septate ascospores and forming coelomycetous asexual morphs (Senanayake et al. 2015; Maharachchikumbura et al. 2016). Three genera are accepted in this family, Amphisphaeria Ces & De Not., Griphosphaerioma Höhn., and Lepteutypa Petr. (Wijayawardene et al. 2018a). An updated evolutionary relationship of the family in Xylariomycetidae was presented by Samarakoon et al. (2016) and Hongsanan et al. (2017). Amphisphaeria Ces. & De Not. Amphisphaeria was established by Cesati and De Notaris (1863) without assigning a generic type. Petrak (1923) proposed A. umbrina (Fr.) De Not. as the lectotype of Amphisphaeria. Hyde et al. (1996) epitypified and described A. umbrina. Senanayake et al.

Based on phylogenetic analyses of a combined LSU, SSU and ITS sequence dataset (Fig. 109) coupled with morphological characteristics, we therefore, introduce a new species from intertidal branches and twigs of Suaeda monoica Lam. (Amaranthaceae) in India. Amphisphaeria mangrovei Devadatha & V.V. Sarma, sp. nov. Index Fungorum number: IF554279; Facesoffungi number: FoF04273, Fig. 110 Etymology: Named after the fungal habitat from marine environment, where the fungus found. Holotype: AMH-9948 Saprobic on intertidal branches and twigs of Suaeda monoica. Sexual morph Ascomata 150–280 lm high, 140– 250 lm diam. ( x = 192 9 211 lm, n = 10), immersed to erumpent, globose to subglobose, gregarious to solitary, coriaceous, brown, short papillate, ostiolate. Ostioles 45– 60 lm long, 35–45 lm diam. ( x = 50 9 40 lm, n = 10), short, periphysate, brown, 0.5–2 lm ( x = 1.5 lm, n = 20). Peridium equal in thickness, 10–20 lm wide ( x = 13 lm, n = 10), both at the base and sides, comprising two layers, inner stratum with 3–4 layers of hyaline to light brown cells of textura angularis and outer stratum with 2–3 layers of light brown to brown cells of textura angularis, fusing with the host tissue. Paraphyses 1–2 lm wide ( x = 1.7 lm, n = 20), filamentous, septate, longer than asci, embedded in a gelatinous matrix. Asci 80–130 9 5–10 lm ( x = 100 9 8 lm, n = 30), 8-spored, unitunicate, cylindrical to obclavate, apically rounded with a J-, apical ring, short pedicellate.

Colonies on MEA reaching 80–90 mm diam. after 7 days of incubation at room temperature, cream to white from above, yellow and white at margin from below, granular and cottony, undulate, umbonate, irregular. Material examined: INDIA, Tamil Nadu, Tiruvarur, Muthupet mangroves (10.4°N 79.5°E), on intertidal branches and twigs of Suaeda monoica, 29 October 2016, B. Devadatha, AMH-9948 (holotype), ex-type living culture, NFCCI-4247. GenBank numbers: ITS = MG844283, LSU = MG767311, SSU = MG844279. Notes: Amphisphaeria mangrovei differs from other Amphisphaeria species in having smaller ascomata, asci and ascospore dimensions and the marine habitat. Amphisphaeria mangrovei has similar morphological characters to A. sorbi such as clypeate ascomata, asci with J-, apical ring and single, median septate, ellipsoidal ascospores (Senanayake et al. 2015). However, A. sorbi has larger ascomata, asci and ascospores, and slightly constricted ascospores with a thick mucilaginous sheath. Amphisphaeria umbrina and A. vibratilis (Fuckel) E. Müll. have clypeate ascomata, asci with J ? , discoid subapical rings and larger ascospores. Phylogenetic analyses of a combined LSU, SSU and ITS regions reveal that A. mangrovei is sister to A. sorbi and A. umbrina with significant support (96% ML, 90% MP and 1.00 BYPP; Fig. 109). Based on morphological characters and molecular phylogenetic analyses, a new species A. mangrovei is introduced. Sporocadaceae Corda. Jaklitsch et al. (2016b) proposed the family Sporocadaceae based on morphological observations and phylogenetic analyses of a concatenated ITS-LSU sequence dataset with asexual morph genera that are acervular coelomycetes having hyaline, pale or dark brown, septate conidia. The type genus is Seimatosporium Corda (Jaklitsch et al. 2016b). The family Sporocadaceae hitherto includes 22 genera (Jaklitsch et al. 2016b; Wijayawardene et al. 2017a, 2018a). We follow the latest treatment and updated accounts of Sporocadaceae in Jaklitsch et al. (2016b), Maharachchikumbura et al. (2017) and Wanasinghe et al. (2018). The updated phylogenetic analyses are derived from Maharachchikumbura et al. (2017) and Wanasinghe et al. (2018). Bartalinia Tassi We follow the latest treatment and updated accounts of Bartalinia in Jaklitsch et al. (2016b) and Wanasinghe et al. (2018). In this study, Bartalinia kunmingensis is introduced from Zea mays (Poaceae) in Yunnan, China based on morphological characteristic and phylogenetic analyses of ITS and LSU sequence data (Fig. 111). Bartalinia kunmingensis Thiyag., Wanas., Phookamsak & K.D. Hyde, sp. nov. Index Fungorum number: IF556209; Facesoffungi number: FoF05717, Fig. 112 Etymology: The specific epithet ‘‘kunmingensis’’ refers to Kunming City, Yunnan, China, where the holotype was collected. 123 Fungal Diversity Holotype: KUN-HKAS 102242 Saprobic on dead leaves of Zea mays. Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata 80–110 lm high, 110–140 lm diam. ( x = 126.2 9 99 lm, n = 10), pycnidial, dark brown to black, immersed, slightly raised, solitary to gregarious, uniloculate, globose to subglobose, glabrous, ostiolate, with a minute papilla. Conidiomata walls 8–20 lm wide, slightly thick-walled, of equal thickness, comprising several cell layers of brown, pseudoparenchymatous cells of textura angularis, paler towards the inner layers. Conidiophores arising from the inner cavity, reduced to conidiogenous cells. Conidiogenous cells (3.6–)4–7.5 9 2–5 lm ( x = 5.4 9 2.8 lm, n = 30), holoblastic, phialidic, rarely with 1–2 percurrent proliferations, discrete, hyaline, ampulliform to subcylindrical, or obclavate, aseptate, smooth-walled. Conidia (17.5–)20–25 9 3–4 lm ( x = 22.1 9 3.9 lm, n = 30), cylindrical to subcylindrical, straight to slightly curved, 4-septate, not constricted at the septa, with longest cell at the second from base, bearing appendages; basal cell 2.5–4 lm long ( x = 3.2 lm), obconic, truncate at base, hyaline, thin and smooth-walled, second cell from the base 6.5–8 lm long ( x = 7.4 lm), pale yellowish, third cell 4–5.5 lm long ( x = 4.8 lm), pale yellowish, fourth cell 4–5.5(–6) lm long ( x = 5 lm), pale yellowish, apical cell 2–3(–3.7) lm long ( x = 2.9 lm), conical, hyaline and smooth-walled, forming three-branched tubular, flexuous, 10–20 lm long apical appendages; basal appendages 5–6 lm long, single, absent at immature state, tubular, unbranched, centric. Culture characteristics: Colonies on PDA reaching 38–40 mm diam. after one week at room temperature. Colony dense, irregular in shape, flat, slightly raised, surface smooth, with edge undulate, floccose to fluffy, entire margin, forming black stromatic after 2 months; from above, white yellowish to cream at the margin, grey yellowish to dark yellowish, slightly radiated outwards colony, from below, black; not producing pigmentation on agar medium. Material examined: CHINA, Yunnan Province, Kumming, Kunming Institute of Botany, on dead leaves of Zea mays L. (Poaceae), 5 November 2015, D.S. Tennakoon, COE002 (KUN-HKAS 102242, holotype), ex-type living culture, KUMCC 18-0178. GenBank numbers: ITS = MK353083, LSU = MK353085, SSU = MK353148, RPB2 = MK492668, TEF1-a = MK492656. Notes: Phylogenetic analyses of a combined ITS and LSU sequence dataset (Fig. 111) show that Bartalinia kunmingensis (KUMCC 18-0178) clusters with Bartalinia species and is sister to B. robillardoides Tassi (CBS 122705, ex-epitype strain). A comparison of ITS region shows that B. kunmingensis is not significant different from B. robillardoides (only two differentiated nucleotide 123 bases); however, B. kunmingensis is different from B. robillardoides in 207/890 bp (23.2%) in RPB2 region. We therefore, identify our isolate as a new species which was found from corn (Zea mays) in China. Bartalinia kunmingensis differs from B. robillardoides (CBS H-21728) in having smaller conidiomata and paler yellowish conidia. (Crous et al. 2014a). Robillarda Sacc. The genus Robillarda was introduced by Saccardo (1880a) and is typified by R. sessile Sacc. This genus contains about 38 species (Crous et al. 2015a). The asexual morph has been reported with its unique characteristics such as solitary or gregarious, separate, subglobose, unicellular, immersed, ostiolate, glabrous pycnidia, holoblastic, ampulliform, hyaline, conidiogenous cells, originating on the inner wall of the pycnidium and ellipsoidal, 1-septate, smooth-walled, hyaline conidia with single branched, apical appendage (Crous et al. 2015a; Borse et al. 2016; Wijayawardene et al. 2016). In this study, the new species, Robillarda mangiferae is introduced from leaf blight on mango in Yunnan, China. Robillarda mangiferae Thiyag., Wanas., Phookamsak & K.D. Hyde, sp. nov. Index Fungorum number: IF556210; Facesoffungi number: FoF05718, Fig. 113 Etymology: The specific epithet ‘‘mangiferae’’ is based on the host genus Mangifera, from which the taxon was isolated. Holotype: KUN-HKAS 102245 Associated with a leaf blight symptom on Mangifera. Sexual morph Undetermined. Asexual morph Coelomycetous.

Material examined: CHINA, Yunnan Province, Xishuangbanna, Jinghong, Nabanhe, associated with leaf blight symptom on living leaf of Mangifera sp., 21 November 2015, R. Phookamsak, XB011 (KUN-HKAS 102245, holotype), ex-type living culture, KUMCC 18-0180. GenBank numbers: ITS = MK353084, LSU = MK353086, SSU = MK353149. Notes: Robillarda mangiferae resembles Robillarda species in having oblong to subfusoid, septate conidia, with an apical cell modified into a branched appendage. However, R. mangiferae can be distinguished from other Robillarda species by its appendage being straight, nonflexuous, broad tubular and narrower towards the apex, with inconspicuous septa at the apex, as well as its conidiogenous cells being holoblastic and proliferating percurrently. Robillarda species have flexuous, narrow tubular, aseptate appendages and holoblastic conidiogenous cells, proliferating sympodially or percurrently near the apex (Crous et al. 2015a; Wijayawardene et al. 2016). Phylogenetic analyses of a combined ITS and LSU sequence dataset show that R. mangiferae clusters with other Robillarda species and Ellurema indica Nag Raj & W.B. Kendr. [current name = Hyalotiopsis Punith., 123 Fungal Diversity proposed by Réblová et al. (2016), and Wijayawardene et al. (2016)] in Sporocadaceae, but the species forms a distinct lineage at the base of this clade with moderate support (92% ML and 1.00 BYPP; Fig. 111). Robillarda mangiferae differs from Ellurema indica in having oblong to ellipsoidal, or subfusoid, (0–)1-septate conidia, with straight, non-flexuous, broadly tubular apical appendages. The asexual morph of Ellurema indica (= Hyalotiopsis) has cylindrical to fusiform or obclavate conidia, with more than 1-septate and 2–3 apical bi- or tri-furcate, filiform, flexuous appendages (Wijayawardene et al. 2016, 2017a). Based on morphological characteristics and phylogenetic analyses of a combined ITS and LSU sequence dataset (Fig. 111), we hence, introduce a new species, R. mangiferae in this study. Xylariales Nannf. Diatrypaceae Nitschke We follow the latest treatment and updated accounts of Diatrypaceae in de Almeida et al. (2016), Shang et al. (2017, 2018) and Senwanna et al. (2017). A higher level classification with divergence time estimates for Diatrypaceae was provided by Hongsanan et al. (2017) and placed the family in order Xylariales (Xylariomycetidae, Sordariomycetes) and a similar scheme is followed in Wijayawardene et al. (2018a). A novel species, Peroneutypa mangrovei is introduced in Diatrypaceae based on analysis of a combined ITS and TUB2 sequence dataset (Fig. 114), coupled with morphological characteristics. In addition, the new genus Neoeutypella is introduced as a monotypic genus to accommodate N. baoshanensis. The new genus was collected from dead wood in Baoshan, China. The sexual and asexual morphs are described and illustrated. Neoeutypella M. Raza, Q.J. Shang, Phookamsak & L. Cai, gen. nov. Index Fungorum number: IF555373; Facesoffungi number: FoF04927 Etymology: The generic epithet ‘‘Neoeutypella’’ refers to the taxon resembling Eutypella. Saprobic on dead wood of Pinus armandii. Sexual morph Ascostromata entostromatic, carbonaceous, visible as black, solitary to gregarious, globose to long irregular in shape on host surface, erumpent through host epidermis, producing yellow pigments surrounding ascostroma. Ascomata perithecial, black, immersed to semi-immersed in stromatic tissues, aggregated, globose or subglobose, ostiolate, papillate, slightly conspicuous, with periphyses. Peridium thickened unequally, two-layered, outer layer comprising 5–7 layers of thick-walled, hyaline to dark brown cells of textura angularis, inner layer comprising 3–5 layers of thin-walled, hyaline to brown cells of textura prismatica. Hamathecium comprising aseptate, filamentous paraphyses, tapering toward the apex, embedded in hyaline gelatinous matrix. Asci 8-spored, unitunicate, spindleshaped, long pedicellate, apically rounded with refractive cytoplasmic strands, amyloid, with a J ? , subapical ring. Ascospores overlapping 1–3-seriate, allantoid, slightly or moderately curved, initially hyaline, becoming pale brown at maturity, aseptate, mostly with small 1–2 guttules. Asexual morph Hyphae branched, smooth, hyaline, septate. Conidiophores long, branched, with phialides, mononematous, macronematous, hyaline. Conidiogenous cells smooth-walled, hyaline, holoblastic, discrete, phialidic, doliiform, ampulliform or irregular in shape. Conidia filiform, solitary, aseptate, smooth-walled, unbranched, hyaline to pale yellow. Type species: Neoeutypella baoshanensis M. Raza, Q.J. Shang, Phookamsak & L. Cai Notes: Neoeutypella resembles Eutypella (Nitschke) Sacc. in forming large entostroma, 8-spored, spindleshaped asci and allantoid ascospores, with a libertella-like asexual morph. Phylogenetic analyses of maximum likelihood, maximum parsimony and Bayesian inference based on the combined ITS and TUB2 sequence dataset (Fig. 114) show that Neoeutypella baoshanensis groups with Eutypella caricae (De Not.) Berl. (strains EL51C and GL08362). Sequences of these two strains are available in GenBank, but no morphological description is available for comparative studies. The two Eutypella caricae strains and Neoeutypella form a distinct lineage from Eutypella sensu stricto. Acero et al. (2004) mentioned that these two strains might have been misidentified and a taxonomic revision of these species is needed. Eutypella caricae and Neoeutypella are phylogenetically closely related to Diatrypella banksiae Crous which produced an asexual morph (Crous et al. 2016a). Nevertheless, Neoeutypella can be differentiated from D. banksiae in shape and size of conidia. Neoeutypella baoshanensis (see below) has filiform conidia [(16.5–)25–37(–40) 9 1.2–1.9 lm], whereas Diatrypella banksiae has spindle-shaped conidia [(25–)27–30(– 35) 9 1.5(–2) lm] (Crous et al. 2016a). Based on morphological comparison of our new taxon and Eutypella caricae described by Saccardo (1882) and Berlese (1902), Neoeutypella baoshanensis (99% similarity in ITS, 90% similarity in TUB2) differs from Eutypella caricae in having larger asci (N. baoshanensis, (45– )52–110(–125) 9 (19–)26–37(–40) versus 35–45 9 6–7, E. caricae) and ascospores (N. baoshanensis, (30–)35–43(– 50) 9 (8–)9–11(–12) versus 9–11 9 2.5–3, E. caricae) (Saccardo 1882; Berlese 1902). Neoeutypella baoshanensis has spindle-shaped asci and pale yellowish to pale brown ascospores, whereas E. caricae has clavate asci and hyaline ascospores (Saccardo 1882; Berlese 1902).

Asexual morph Undetermined. Culture characteristics: Colonies on MEA reaching 50–80 mm diam. after 15 days of incubation at room temperature, initially white, becoming light grey at maturity, reverse light yellow, cottony, punctiform, flat, circular, entire. Material examined: INDIA, Puducherry, Thengaithittu mangroves (11.5°N 79.5°E), on decaying wood of Avicennia marina (Forssk.) Vierh. (Acanthaceae), 12 March 2016, B. Devadatha (AMH-9944, holotype), ex-type living culture, NFCCI-4246. GenBank numbers: ITS = MG844286, LSU = MG844278, SSU = MG844282, TUB2 = MG844282. Notes: Peroneutypa mangrovei shares similar morphological characters such as J-, apical ring asci, overlapping ascospores dimensions with P. diminutispora D.A.C. Almeida et al. (de Almeida et al. 2016). However, it differs in having perithecia single or in groups of up to four, shorter ascomata and ostiole, longer asci (14–20 9 3–4 lm) and its exclusive occurrence in marine habitat. Peroneutypa diminutispora has perithecia arranged in a single layer, occurring singly or in groups of up to seven, shorter asci (8–14 9 3.5–5 lm) that are urn-shaped (de Almeida et al. 2016). Peroneutypa cosmosa (Speg.) Carmarán & A.I. Romero has larger asci (18–25 9 5–7 lm) with J?, apical rings and longer ascospores (6–8 lm) (Carmarán et al. 2006). Peroneutypa longiasca Senwanna et al. and P. mackenziei Q.J. Shang et al. have longer ascospores (5–7 lm) (Senwanna et al. 2017; Shang et al. 2017). This is the first report of Peroneutypa species from a marine habitat (Jones et al. 2015). ITS and TUB2 gene phylogeny also supports P. mangrovei as distinct forming an independent lineage, sister to Eutypa microasca E. Grassi & Carmarán, and cluster with Peroneutypa diminutispora and P. cosmosa (Fig. 114). A comparison of ITS nucleotides between P. mangrovei and P. dimunitispora (GenBank no. KM396647) results in 7.4% (47 nucleotides) and 5.5% (26 nucleotides) along with P. cosmosa (GenBank no. KF964568). Hypoxylaceae DC. We follow the latest treatment and updated accounts of Hypoxylaceae in Daranagama et al. (2018) and Wendt et al. (2018). Hypoxylon Bull. Hypoxylon is the largest genus in Hypoxylaceae with over 140 accepted species classified on the basis of morphology, phylogeny and chemotaxonomy (Kuhnert et al. 2014; Wijayawardene et al. 2017a). More than 1000 epithets are listed in Index Fungorum (2019). We introduce a new species Hypoxylon teeravasati based on morphology and multigene analysis (Fig. 117).

Material examined: INDIA, Tamil Nadu, Tiruvarur, Muthupet mangroves (10.4°N 79.5°E), on decaying wood of Avicennia marina (Acanthaceae), 28 November 2015, B. Devadatha, AMH-9906 (holotype), ex-type living culture, NFCCI-4216; ibid. on decaying branches and twigs of Suaeda monoica Forssk. ex J.F. Gmel, PUFD4 (paratype at Pondicherry University, Puducherry). GenBank numbers: ITS = KY863509, LSU = MF385274, SSU = MF385273, RPB2 = MG986895, TEF1-a = MF182401, TUB2 = MG986894. Notes: Multigene analysis shows that Hypoxylon teeravasati shares a strongly supported sister relationship with H. jaklitschii Sir & Kuhnert and H. lenormandii Berk. & M.A. Curtis as a basal taxon. All three taxa constitute a single monophyletic clade with high support (Fig. 117), but their relationships with other Hypoxylon species are not well-resolved. We found distinct nucleotide base pair differences between H. teeravasati and H. jaklitschii across ITS and TUB2 genes [36 within ITS and 23 within TUB2] which is in agreement with guidelines by Jeewon and Hyde (2016) to establish new species. Hypoxylon teeravasati, H. lenormandii, H. jaklitschii and H. croceum J.H. Mill. share similar stromatal characters and overlapping asci dimensions. However, H. teeravasati can be easily distinguished from H. lenormandii, H. jaklitschii and H. croceum in having a burnt sienna surface, with KOH extractable pigments eye brown and larger perithecia. Hypoxylon lenormandii has surface greyish sepia, fuscous, or brown vinaceous, dull orange brown to dark brown granules beneath and between perithecia, with KOH extractable pigments hazel, fulvous, umber or ochreous (Kuhnert et al. 2015; Liu et al. 2015a). Hypoxylon jaklitschii has a sepia to dark brick surface, pruinose, with orange brown or dark brown granules immediately beneath 123 the surface and between perithecia, with KOH extractable pigment umber or dark brick and smaller ascospores (9.5–12 9 4–5.5 versus 9–15 9 4–7) (Kuhnert et al. 2015). Hypoxylon croceum is distinguished from H. teeravasati in having an initially sepia or fuscous surface, becoming dark brown at maturity and abelline or hazel KOH extractable pigments (Miller 1933). Hypoxylon croceum is the only report of Hypoxylon species from a marine habitat (Jones et al. 2015). Hypoxylon teeravasati is saprobic on decaying branches and twigs of Avicennia marina and Suaeda monoica, exclusively from marine environments. Hypoxylon lenormandii and H. jaklitschii have been reported from terrestrial habitats. Phylum Basidiomycota R.T. Moore We follow the latest treatment of Basidiomycota in Zhao et al. (2017). Class Agaricomycetes Doweld The classifications of the families in Agaricomycetes herein follow Hibbett et al. (2014) and Zhao et al. (2017). The subclasses, orders and families of Agaricomycetes are listed in alphabetical order. Subclass Agaricomycetidae Parmasto Agaricales Underw. Agaricaceae Chevall. We follow the latest treatments and updated accounts of Agaricaceae in Zhao et al. (2016), Zhou et al. (2016) and Hyde et al. (2017). Three specimens were collected and preliminary BLAST using ITS sequence data indicated that two taxa belong to Agaricus sect. Xanthodermatei and the third to Coprinus. Based on distinctive morphological characteristics and phylogenetic support, two novel species of Agaricus sect. Xanthodermatei as well as Coprinus trigonosporus sp. nov. are introduced in this study. An updated phylogenetic tree based on maximum likelihood and Bayesian inference analyses also confirms their placement (Fig. 119). Agaricus L.: Fr. We follow the latest treatment and updated accounts of Agaricus in Thongklang et al. (2014), Karunarathna et al. (2016), Zhao et al. (2016) and Zhou et al. (2016).

Pileipellis a cutis composed of hyphae of 4.6–14.4 lm diam., smooth, cylindrical, slightly constricted at septa, pigment intracellular, light brown or brown. Material examined: CHINA, Sichuan Province, Miyi County, 13 September 2015, ZRL20151118 (HMAS 0278359, holotype). Host and habitat: Solitary on soil in forest with bamboo around. Distribution: Sichuan Province (China). GenBank numbers: ITS = MG763128, LSU = MG765263, TEF1-a = MG765265. Notes: The phylogenetic trees generated by maximum likelihood and Bayesian inference analyses (Fig. 119) show that Agaricus memnonius forms a distinct lineage within Agaricus sect. Xanthodermatei in the clade Xan II and the tree topology is similar with previous studies (Zhao et al 2016; Zhou et al. 2016; Parra et al. 2018). Agaricus memnonius has relatively small and slender basidiomes, which are similar to the European species A. laskibarii L.A. Parra & Arrillaga, A. xanthodermulus Callac & Guinb. and A. parvitigrinus Guinb. & Callac (Parra 2013). However, A. memnonius has black-brown and triangular scales on the pileus, while the other three species have greyish brown and not triangular scales. Some species 123 described from China also have small and slender basidiomes, such as A. gregariomyces J.L. Zhou & R.L. Zhao and A. karstomyces R.L. Zhao. However, A. gregariomyces has larger and elongate basidiospores (5.6–6.3 9 3.5–4.0 lm, Q = 1.6–1.9; Zhou et al. 2016). Agaricus karstomyces has dot-like scales on the pileus, while A. memnonius has triangular scales. Based on phylogenetic and morphological studies, A. memnonius is introduced as a new species and is characterized by its distinct phylogenetic position in section Xanthodermatei, small and slender basidiome, black-brown and triangular scales on the pileus, and the single and multiseptate cheilocystidia. Agaricus langensis M.Q. He & R.L. Zhao, sp. nov. Fungal names: FN570534; Facesoffungi number: FoF03941, Fig. 121 Etymology: The Latin epithet ‘‘langensis’’ meaning ‘‘originating from Lang’’ refers to the Lang County where the holotype was collected. Holotype: HMAS 0278317 Basidiomes flavescent when rubbed. Pileus 26–49 mm diam., parabolic when young, then convex, disc slightly subumbonate, margin straight, sometimes with appendiculate remains of veil; surface dry, with grayish brown fibrillose scales against white background, scales appressed, covering the whole pileus, denser at disc, scattered towards the margin. Lamellae up to 5 mm broad, free, crowded, pink, edge even, intercalated with lamellulae. Annulus up to 6 mm in diam., superous, double, membranous, white when fresh, yellowish when dry, pendant, upper side smooth, lower side cogwheel, white, edge light brown. Stipe 59–76 9 6–7 mm (7–10 mm at base), white, hollow, cylindrical, surface dry, smooth or slightly fibrillose, with rhizomorphs. Context fleshy, white. Odour unknown. KOH reaction: positive yellow. Schäffer’s reaction: negative. Basidia 18.5–25.3 9 6.7–8.9 lm, clavate, hyaline, 4-spored, smooth.

Cheilocystidia absent. Pileipellis a cutis composed of hyphae of 4.8–12.1 lm diam., smooth, cylindrical, slightly constricted at septa, hyaline, light brown or brown. Material examined: CHINA, Tibet, Lang County, Gongga Village, Alt. 3384 m, 29°160 N, 93°110 E, S-Y. Su, ZRL20152282 (HMAS 0278317, holotype). Habit and habitat: Scattered on soil in forest. Distribution: Tibet (China). GenBank numbers: ITS = MG763129, LSU = MG765264, TEF1-a = MG765266. Notes: Agaricus langensis (HMAS 0278317) belongs to a clade called Xan III (Thongklang et al. 2014; Parra et al. 2018) which is present (but not always indicated) in all previous multigene trees of Agaricus sect. Xanthodermatei (Zhao et al. Fungal Diversity Fig. 119 Maximum likelihood tree of Agaricus sect. Xanthodermatei based on LSU, TEF1-a and ITS sequences with Agaricus campestris (LAPAG370) as the outgroup taxon. The bootstrap values and Bayesian posterior probabilities more than 50%/0.90 (BS/BYPP) are indicated at the nodes. The branches in bold mean the related PP [ 0.95, ‘‘T’’ refers to sequences from type specimen 2016, Zhou et al. 2016, Parra et al. 2018) and which includes in our tree A. flavidodiscus L.A. Parra et al., A. langensis and 32 other species (Fig. 119). The new species forms a sister lineage with Agaricus sp. (ZRL2012629) with moderate support (75% ML and 1.00 BYPP) in our phylogenetic analyses (Fig. 119). Agaricus parvitigrinus Guinb. & Callac resembles A. langensis in the field, because both have small to medium sized basidiomes, a convex pileus covered by greyish fibrillose scales. However, A. langensis has larger basidiospores than those of A. parvitigrinus (5.8 9 3.7 lm; Parra 2013). Agaricus menieri Bon, A. xanthodermulus Callac & Guinb. and A. xanthodermus Genev. have similar sized basidiospores, but have distinct cheilocystidia (Parra 2013), a feature lacking in A. langensis. Agaricus tibetensis J.L. Zhou & R.L. Zhao also has small to medium sized basidiomes, same sized basidiospores as A. langensis, and no cheilocystidia (or rare in A. tibetensis), and both species originated from Tibet (Zhou et al. 2016). However, their ITS sequences differ at 33 base positions, and the molecular phylogeny also indicates that they are different species. Based on the phylogenetic analyses and morphological characteristics, we introduce this new species, which is 123 Fungal Diversity Fig. 120 Agaricus memnonius (HMAS 0278359, holotype). a Basidiome in the field. b Basidiospores. c Cheilocystidia. d Pileipellis hyphae. e Basidia. Scale bars a = 2 cm, c–e = 10 lm, b = 5 lm characterized by its distinct phylogenetic position in sect. Xanthodermatei, small to medium sized basidiomes, relatively large basidiospores and absence of cheilocystidia. Coprinus Pers. Traditionally, Coprinus comprised all coprinoid species (black spore print and mature lamellae, plicate-sulcate pileus) and it was the type genus of the family Coprinaceae Overeem & Weese. On the basis of earlier phylogenetic 123 studies, Redhead et al. (2001) transferred most Coprinus species into four genera of the new family Psathyrellaceae Vilgalys et al. Coprinus comatus (O.F. Müll.) Pers., and a few related species remained in Coprinus, which was transferred to family Agaricaceae (Moncalvo et al. 2002; Vellinga 2004). Coprinus species have rather small to large basidiomes with squamulose pileus, ring-like partial veil and deliquescent lamellae. A phylogenetic tree is presented in Fig. 122. Fungal Diversity Coprinus trigonosporus Tkalčec & Mešić, sp. nov. MycoBank number: MB826852; Facesoffungi number: FoF05719, Fig. 123 Etymology: The species is named after its basidiospores that are often rounded triangular in frontal view. Holotype: CNF 1/6594 Pileus up to 24 mm broad and 32 mm high when still closed, 32–46 mm broad at maturity, ellipsoid to oblong at first, later obtusely conical to subapplanate with broad subumbonate centre, often radially splitting, when young entirely covered with a dense, white universal veil forming imbricate, rather large scales with mostly upturned lower edge, later veil splitting up into patches of different sizes (from one scale to group of scales) except at the centre, surface strongly plicate-sulcate, white at first, becoming pink brown to vinaceous brown and soon black, margin sometimes with few small, white, appendiculate remnants of partial veil at maturity. Lamellae free, crowded, broad, often sinuous when young, white at first, later turning pink to vinaceous brown, soon becoming black, weakly deliquescent. Stipe 34–56 9 5.5–10 mm, tapering upwards or subcylindrical, with subbulbous, obconical, buried base (up to 15 mm wide), white, central, hollow, dry, ± tomentose when young, (sub) glabrous at maturity, partial veil remaining as a white, narrow ring at the top of the base. Context white. Odour and taste fungoid. Spore print black. Basidia 30–62 9 12–24 lm, clavate, 4-spored, thin-walled or moderately thick-walled (up to 1 lm), first hyaline, at maturity partially (in the middle part) or entirely with pale to dark brown parietal pigment, surrounded by 6–12 hymenophysalides (pseudoparaphyses). Hymenophysalides 15–42 9 6–14 lm, clavate, thin-walled, sometimes moderately thick-walled (up to 0.8 lm), hyaline to pale brown.

Material examined: SAUDI ARABIA, Jizan Province, village, 8 km S from Harub, 17°220 0300 N, 42°520 1000 E, 257 m a.s.l., on sandy soil in a courtyard, 22 September 2010, leg. M. Čerkez, CNF 1/6594 (holotype). Habit and habitat: In group (approximately 20 basidiomes), on sandy soil with some sheep dung, among scattered herbaceous plants and bushes in a courtyard. Distribution: So far known only from the type locality in the Kingdom of Saudi Arabia, Jizan Province. GenBank numbers: ITS = MH422561, LSU = MH422563. Notes: Based on a megablast search of NCBIs GenBank nucleotide database, the closest hit using ITS sequence for our new species is Coprinus vosoustii Pilát [GenBank no. JF907844, similarity = 627/668(94%), Gaps = 9/668(1%)]. Phylogenetic analysis based on the ITS sequence data of Coprinus sensu stricto shows that C. trigonosporus formed a distinct lineage and clustered with C. vosoustii and 123 Fungal Diversity C. sterquilinus (Fr.) Fr.. Morphologically, C. trigonosporus is best characterised by a considerable number of cordiform and rounded triangular basidiospores. Other species in the genus have ellipsoid or ovoid basidiospores (van de Bogart 1976; Moreno and Heykoop 1998; Cacialli et al. 1999; Uljé 2005; Crous et al. 2016b). The rather peculiar microscopic characteristic of C. trigonosporus is the large number of hymenophysalides (6–12) surrounding the basidium. Amanitaceae E.-J. Gilbert Amanitaceae is defined as those agarics having bilateral, divergent lamellae trama and a longitudinally acrophysalidic stipe context. The family comprises five genera, Amanita Pers., Catatrama Franco-Mol., Limacella Earle, Limacellopsis Zhu L. Yang et al. and Myxoderma Fayod ex Kühner (Cui et al. 2018). In this family, Amanita is the most species-rich genus (Bas 2000; Tulloss 2005; Yang 2005; Cui et al. 2018). More than 1000 species have been described worldwide with ca. 600 accepted names; about 60 taxa have been reported from India (Yang 2000; Bhatt et al. 2003; Tulloss and Yang 2016). Amanita Pers Amanita was recently discussed by Ariyawansa et al. (2015a), Tulloss and Yang (2016), Tulloss et al. (2016) and Cui et al. (2018). We follow the latest treatment and updated accounts of Amanita in Tulloss and Yang (2016), Tulloss et al. (2016), Tibpromma et al. (2017) and Cui et al. (2018). Two novel species (belonging to Amanita sect. Amanita and A. sect. Vaginatae), collected from the north-western part of Indian Himalaya are introduced together with their morphology and phylogenetic placements (Figs. 128, 131). In addition, A. altipes and A. Fig. 122 Maximum likelihood phylogenetic tree of Coprinus trigonosporus and closely related species based on ITS sequence dataset and calculated with MEGA6.0 software (Tamura et al. 2013). The new species is shown in blue. Maximum likelihood bootstrap values greater than 50% are indicated at the nodes. The tree is rooted with Tulostoma kotlabae and T. niveum. The bar indicates the number of nucleotide substitutions per site 123 melleialba are reported from Thailand for the first time, which was established based on morphology and DNA sequence analyses of LSU and RPB2 regions (Fig. 124).

Notes: Amanita altipes, originally described from southwestern China by Yang et al. (2004), resembles several species in the section Amanita, such as A. elata (Massee) Corner & Bas, A. gemmata (Fr.) Bertillon, A. orientigemmata Zhu L. Yang & Yoshim. Doi, A. russuloides (Peck) Sacc., and A. xylinivolva Tulloss et al. Amanita altipes shares some morphological similarities with these yellow to yellowish species which have been discovered in either Europe or Asia. Molecular analyses indicate that A. altipes is a distinct species closely related to A. melleialba. The combined gene phylogenetic analyses indicate that Thai A. altipes sequences clustered with A. altipes sequences from China with 100% ML support (Fig. 124). 123 Amanita flavoalba Mehmood & R.P.

Host and habitat: On ground under Abies pindrow (Royle ex D. Don) Royle in temperate coniferous forest Distribution: Indian Himalaya. GenBank numbers: LSU = KY861748 (CAL 1405), MF695813 (TM 16-1280). Notes: A combination of macro- and micromorphological features like inamyloid basidiospores and bulbous stipe base place A. flavoalba in Amanita [subg. Amanita] sect. Amanita (Yang 1997). Amanita flavoalba is distinct from other known species of Amanita sect. Amanita by a combination of characteristics: smaller basidiomes, yellow to vivid yellow pileus centre and whitish to yellowish white toward pileus margin, membranous to submembranous universal veil on pileus, subglobose basidiospores, universal veil on the pileus composed of abundant filamentous hyphae mixed with scattered inflated cells. In the field, A. flavoalba is easily recognized by its yellow pileus with yellowish white margin, easily detachable universal veil on pileus in the form of membranous to submembranous patches and its occurrence under Abies pindrow. The presence of subglobose basidiospores, very abundant filamentous hyphae mixed with scattered inflated cells in universal veil on the pileus are also quite striking. Amanita flavoalba might be confused with A. melleialba Zhu L. Yang et al. (originally described from China), however, the latter possesses a honey pileus with longer marginal striation, subconical to granular universal veil remnants on pileus, ellipsoid to sometimes broadly ellipsoid basidiospores (7.5–9.5 9 6–7 lm, with Q = 1.41) and 123 it occurs in subtropical forests dominated by plants of Fagaceae (Ariyawansa et al. 2015a). Amanita flavoalba is similar to A. pseudosychnopyramis Yang Y. Cui et al., but the latter has yellowish brown to brownish pileus, universal veil remnants as conical to pyramid, grey to brownish grey warts and it occurs in subtropical forests of Fagaceae (Ariyawansa et al. 2015a). Amanita parvipantherina Zhu L. Yang et al. and A. subparvipantherina Zhu L. Yang et al. are easily segregated from A. flavoalba by the universal veil remnants on pileus in the form of subconical to granular warts (Yang et al. 2004; Ariyawansa et al. 2015a). Amanita parvipantherina also has broadly ellipsoid to ellipsoid basidiospores (8.5–11.5 9 6.5–8.5 lm, Q = 1.38; Yang et al. 2004) and A. subparvipantherina has broadly ellipsoid to ellipsoid basidiospores (9–11.5 9 6.5–8 lm, with Q = 1.38; Ariyawansa et al. 2015a). Amanita flavoalba resembles A. altipes by its yellowish pileus but A. altipes pileus has a brownish tinge and its basidiospores are globose to subglobose (8–10 9 7.5–9.5 lm, with Q = 1.07; Yang et al. 2004). Amanita elata (originally described from Singapore) differs from A. flavoalba by its pale dingy to ochraceous buff pileus with very faint sulphur-yellow tinge, exannulate stipe, smaller basidiospores (7–8.5 9 6.8–7.7 lm) and its occurrence in tropical forests (Corner and Bas 1962). Our molecular phylogenetic analysis shows closeness (though well separated in Fig. 128) with a few taxa (in Amanita sect. Amanita) like A. xylinivolva (originally described from Colombia; GenBank no. FJ890036), A. crenulata Peck (originally described from the USA; GenBank no. HQ539687) and A. breckonii Thiers & Ammirati (originally reported from the USA; GenBank no. KJ535440).

Scale bars a = 10 mm, f–i = 20 lm Amanita xylinivolva can be easily separated by its basidiomes without a pileal umbo, white to off-white to dingy grey volval remnants, whitish buff lamellae, marked to abrupt bulb and microscopically, globose to subglobose basidiospores with comparatively lower Q value (8–10.2 9 7.2–9.5 lm, Q0 = 1.08; Tulloss et al. 1992). Amanita crenulata has a brownish beige to greyish pileus, universal veil on pileus as flocculose to subpyramidal warts and subglobose to broadly ellipsoid basidiospores (Q0 = 1.08) (Peck 1900). Amanita breckonii has ellipsoid to elongate basidiospores (9.8–12.8 9 6.2–8.7 lm, Q0 = 1.65) and clamp connections at the base of basidia (Thiers and Ammirati 1982). Macro- and micromorphology coupled with the LSU-based phylogenetic analysis corroborate A. flavoalba as a novel species. Amanita melleialba Zhu L. Yang, Qing Cai & Yang Y.

Amanita ceciliae (Berk. & Broome) Bas, A. liquii Zhu L. Yang et al., A. griseofolia Zhu L. Yang, and A. cinctipes Corner & Bas are species of sect. Vaginatae which are somewhat similar to A. subtropicana on the basis of friable universal veil at the stipe base. Amanita ceciliae, a European species, can be easily segregated from A. subtropicana by its yellow brown to grey-brown or olive-brown pileus with greyish to brownish universal veil remnants (Phillips 1990; Breitenbach and Kränzlin 1995). Amanita liquii, originally described from southwestern China, differs from A. subtropicana by its dark brown to blackish pileus with dark universal veil remnant and globose to subglobose basidiospores. Furthermore, it is associated with Abies and Picea (Yang et al. 2004). Amanita griseofolia differs by its grey to brownish grey pileus and felted to verrucose universal veil and globose to subglobose basidiospores (10–13.5 9 9.5–13 lm; Yang 2004). Amanita cinctipes (originally described from Singapore) is distinct from A. subtropicana by its mouse grey to greyish brown pileus with abundant universal veil remnants on the base of the stipe forming 2–4 rings and globose to subglobose basidiospores (Corner and Bas 1962). Three Indian species, Amanita cornelii Mehmood et al., A. emodotrygon Mehmood et al. and A. rajendrae Mehmood et al. (GenBank no. KX528072, KX539266 and MF170174, respectively, in Fig. 131) of sect. Vaginatae are easily segregated from A. subtropicana by their distinct saccate universal veil on stipe base (Das et al. 2017b; Tibpromma et al. 2017). Initial BLASTn search results of LSU sequence from Indian collection (TM 17-1574) against the NCBI database exhibited 87% similarity with 100% query coverage of Amanita subtropicana to ‘‘Amanita sp. Aus09’’ (GenBank no. KY349232). Phylogenetically (Fig. 131), A. subtropicana might have some closeness with Amanita sp. (Aus09), A. madagascariensis L.P. Tang et al. and A. strobilaceovolvata (Beeli) E.-J. Gilbert. Unfortunately, no morphological description of Amanita sp. (Aus09) is available for comparison of important morphological characteristics. Amanita madagascariensis originally described from East Africa can easily be separated by its dirty white or dull white pileus covered with greyish to brownish grey universal veil remnants and occurrence under Eucalyptus (Tang et al. 2015). Amanita strobilaceovolvata, originally described from the Congo, has a yellow to pale yellow pileus, a strobiloid saccate universal veil and subglobose to broadly ellipsoid basidiospores (8–10 9 7–9 lm) (Gilbert 1940; Tang et al. 2015). Hygrophoraceae Lotsy The family Hygrophoraceae contains 25 genera and over 600 species (Lodge et al. 2014). Most species in the family prefer a humicolous habitat, except for a few that are lignicolous, ectomycorrhizal, or on mosses (Griffith et al. 2002). Hygrocybe (Fr.) P. Kumm Hygrocybe is cosmopolitan in distribution (Senthilarasu et al. 2010). Currently, 457 species are listed as legitimate in Index Fungorum and MycoBank (2019). The genus is characterized by the presence of variously coloured basidiomes with waxy lamellae, absence of veilar remnants on the pileus margin as well as stipe, and white, inamyloid, smooth basidiospores (Boertmann 1995; Babos et al. 2011; Lodge et al. 2014; Hosen et al. 2016). Most species predominantly grow on soil, except for a few found on tree trunks or on logs (Lodge et al. 2006). Hygrocybe lucida K. Acharya & A.K. Dutta, sp. nov.

Habit and habitat: Uncommon, solitary or scattered, on humus-rich soil. Distribution: India. GenBank numbers: ITS = MH599084 (CUH AM123); ITS = MH599083 (CUH AM126). Notes: The distinguishing features of Hygrocybe lucida include small basidiome size, a convex (when young) to somewhat infundibuliform (at maturity), orange to reddish orange pileus that does not change colour on bruising or with age; white, adnexed to broadly adnate lamellae; an orange or greyish orange stipe; dimorphous basidiospores and basidia; absence of cheilo- and pleurocystidia; an ixotrichodermium-type pileipellis; regular lamellae trama composed of short hyphal elements (29–76 lm long); an ixocutis-type stipitipellis; absence of caulocystidia; and presence of clamp connections in all parts of the basidiome. This combination of features place the present species in sect. Firmae of subgen. Pseudohygrocybe (Pegler and Fiard 1978; Pegler 1986; Cantrell and Lodge 2001; Lodge and Ovrebo 2008). The morphological placement is further supported by the molecular phylogenetic analysis based on ITS sequence data (Fig. 134). 123 Fungal Diversity Fig. 131 Maximum likelihood phylogram of Amanita showing the position of Amanita subtropicana. Phylogenetic analysis was conducted in MEGA 6.0 (Tamura et al. 2013) based on LSU sequence data. Bootstrap support values ([ 50%) obtained from maximum likelihood analysis are shown above or below the branches at nodes. The new taxon is highlighted in blue and bold on the tree. Type specimens are in bold. Amanita caesareoides Lj.N. Vassiljeva and A. caesarea (Scop.) Pers. were used as the outgroup taxa Within sect. Firmae, species with more or less similar size of the macrospores include Hygrocybe alwisii (Berk. & Broome) Pegler, H. diversicolor (Petch) Pegler, and H. earlei (Murrill) Pegler. Hygrocybe alwisii, previously reported from India, and differing by a larger pileus (45–55 mm), adnexed to almost free lamellae, a longer stipe (60–70 mm), and a repent epicutis type of pileipellis (Pegler 1986; Leelavathy et al. 2006). Hygrocybe diversicolor has a larger pileus (up to 50 mm) that is olivaceous brown to blackish brown with appressed squamulose surface, longer stipe (30–35 mm), purplish grey to purplish black, and epicutis type of pileipellis (Pegler 1986). 123 Fungal Diversity Hygrocybe earlei, a species known only from Cuba and Trinidad, has a pileus that is initially campanulate and becomes expanded with a broad low umbo, and free to adnexed lamellae. Hygrocybe cf. earlei, previously known only from Panama, has an umbonate pileus, pale yellow lamellae with white edge, a pure white, much longer stipe (up to 40 mm), smaller macrobasidia (24–46 lm long) and microbasidia (22–30 lm long), and presence of an intermittent thin gelatinous coating in the pileipellis (Lodge and Ovrebo 2008). Hygrocybe batistae Singer, described from Brazil and later found in Colombia and Puerto Rico, has similarly coloured basidiomes but differs by its rugulose to rugose pileus, caespitose basidiomes, and presence of coralloid hyphae in the pileipellis (Lodge and Pegler 1990; Cantrell and Lodge 2001; Lodge et al. 2014). Hygrocybe neofirma S.A. Cantrell & Lodge also has similarly coloured basidiomes but has a star-shaped perforation at the pileus centre, light yellow to brilliant yellow lamellae, and larger macrospores (12.8–17.6 9 8–10.4 lm; Cantrell and Lodge 2001). Hygrocybe hypohaemacta (Corner) Pegler, previously placed within sect. Firmae and recently transferred to sect. Velosae based on phylogenetic analysis by Lodge et al. (2014), appears to be close to H. lucida in some morphological characteristics. However, H. hypohaemacta has a convex to plano-convex pileus that is covered by a thick (up to 1.5 mm) greyish gluten, discolorous lamellae with pale golden edge, longer stipe (up to 60 mm), somewhat differently sized macrospores (7–11 9 5–8 lm), presence of polymorphic cheilocystidia, and an epicutistype pileipellis (Pegler and Fiard 1978). Hygrocybe trinitensis (Dennis) Pegler and H. siparia (Berk.) Singer are comparable in having similar smaller pilei (Pegler and Fiard 1978). Hygrocybe trinitensis differs by the presence of coral red lamellae that are broadly adnate with a decurrent tooth, a longer stipe (up to 50 mm), smaller macrospores (7–9 9 4.5–5.5 lm, Q = 1.56), smaller macro- and micro-basidia, and an epicutis-type pileipellis that contains red vacuolar pigments. Hygrocybe siparia, described from Brazil, has an umbilicate pileus with squamulose surface, lamellae with a decurrent tooth, longer macrospores (10–13 lm long, Q = 1.53), and smaller macro-basidia (40–48 lm long). Among phylogenetically related taxa (Fig. 134), Hygrocybe firma (Berk. & Broome) Singer differs by its yellow pileus, strongly decurrent lamellae, and longer macrospores (11–18 lm long) (Berkeley and Broome 1871; Young and Mills 2002). Hygrocybe andersonii Cibula & N.S. Weber, originally described from Horn Island of Mississippi, has densely cespitose growth habit, brownish orange to deep orange lamellae, longer stipe (up to 42 mm long) reddish brown, and large bacilliform Fig. 132 Hygrocybe lucida (CUH AM123, holotype).

Marasmiaceae Roze ex Kühner Marasmiaceae is a family of pale-spored agarics. It has a worldwide distribution and comprises about 54 genera and 1590 species (Kirk et al. 2008). Several of these taxa were previously considered under Tricholomataceae sensu lato (Moncalvo et al. 2002; Matheny et al. 2006). Most species are saprobes that play a leading role in nutrientrecycling and form prominent components of forest ecosystems (Cannon and Kirk 2007). A novel species, Marasmius indojasminodorus is introduced within Marasmiaceae. An updated phylogenetic tree of ITS sequence data based on maximum likelihood and Bayesian inference analyses of the genus Marasmius is provided (Fig. 135). Detailed literature and updated accounts of Marasmius were provided by Wannathes et al. (2009) and Tibpromma et al. (2017). Marasmius Fr.

GenBank accession numbers for all of the sequences are indicated in the tree 123 Fungal Diversity Host and habitat: Uncommon, scattered to gregarious, on dead and decayed leaves and wood of dicotyledonous plants. GenBank numbers: ITS = KY785172, LSU = KY785174 (CAL 1514); ITS = KY785171, LSU = KY785173 (CAL 1515). Notes: The most distinctive combination of features of Marasmius indojasminodorus includes a small to medium sized (12–21 mm diam.), convex to broadly convex, rugulose-striate yellowish brown pileus with a rugulose, olive brown to light brown or yellowish brown disc; adnexed, subdistant (14–16), white to cream, lamellae with lamellulae of 2–3 lengths; a non-insititious, glabrous to slightly velutinous stipe coloured white to cream at apex and light brown to brown at base, with yellowish white to brownish white basal mycelium; strong, sweet, jasmine like odour; ellipsoid basidiospores with a mean size of 8.7 9 3.7 lm (Q = 1.8–2.8); Siccus-type cheilocystidia with main body 10–15 9 3.5–7.5 lm; absence of pleurocystidia; and two types of caulocystidia, Siccus-type in combination with numerous non-setulose cells, cylindrical to irregular in outline (17–36 9 6–11 lm). This combination of features undoubtedly place the present taxon within Marasmius ser. Atrorubentes of sect. Sicci (Wannathes et al. 2009). Among taxa that possess jasmine-like odour, Marasmius jasminodorous Wannathes et al. (Wannathes et al. 2009), described from Northern Thailand, differs by its colouration of pileus (dark reddish brown towards disc with light brown to brownish orange margin), basal mycelium of the stipe (brownish orange), and larger basidiospores with a mean range of 10.1 9 3.6 lm (Qm = 2.8). Marasmius odoratus V.A. Farook & Manim., recently described from Kerala state of India, primarily differs by the presence of ‘‘Globulares-type’’ cells in the pileipellis and is categorized under sect. Globulares (Farook and Manimohan 2015). Among other similar species belonging to sect. Sicci, and phylogenetically close taxa (Fig. 135), M. midnapurensis A.K. Dutta et al., described from India, primarily differs from M. indojasminodorus by the absence of jasmine-like odour, longer basidiospores (10.7–15 lm long, Qm = 3), comparatively broader main-body of cheilocystidia (up to 10 lm broad), and longer (up to 50 lm), and non-setulose caulocystidia (Dutta et al. 2014). The Indonesian taxon, M. araucariae var. siccipes Desjardin et al. differs by its non-rugulose pileus, orange brown all over or with darker disc, discolorous lamellae with orangebrown edge, glabrous stipe, absence of any fragrant odour, and distinctly longer (11–12 9 3–4 lm), subfusoid basidiospores (Desjardin et al. 2000). Marasmius ochroleucus Desjardin & E. Horak, described from New Caledonia and subsequently reported from Northern Thailand, primarily 123 differs by its light yellow to cream pileus, much crowded (L = 20–24, l = 3–4), and intervenose lamellae, and presence of only one type of caulocystidia shaped cylindrical to fusoid-ventricose (Wannathes et al. 2009). The Korean taxon M. occultatiformis Antonı́n et al. has brownish orange to brownish red pileus and slightly paler towards margin, presence of more lamellae (L = 25) finely pubescent towards edge, whitish basal mycelium, somewhat differently sized basidiospores (mean of 7.8 9 4 lm, Q = 1.95), and absence of caulocystidia (Antonı́n et al. 2012). Marasmius araucariae Singer, described from Argentina, has castaneous-ferruginous or ferruginous pileus, more lamellae (16–24), comparatively longer stipe (up to 70 mm long) with fulvous-white basal mycelium, absence of any odour, larger basidiospores (9–12.5 9 2.7– 4.5 lm), and only one type of caulocystidia, subcylindric, 50 9 5.5 lm (Singer 1976). Marasmius napoensis Singer differs by its larger pileus (up to 60 mm diam.) with deeply sulcate margin, distant lamellae, longer stipe (60–77 mm long), absence of any strong odour, and presence of only Siccus-type caulocystidia (Singer 1976). Marasmius pellucidus Berk. & Broome, although phylogenetically related as revealed in Fig. 135, possess Globulares-type of cells in the pileipellis and is categorized under a sect. Globulares (Wannathes et al. 2009). The other distinguishing features of M. pellucidus from that of M. indojasminodorus includes a plano-campanulate to almost applanate pileus, ivory to pale orange towards disc with white to cream or pale yellowish white margin, and presence of comparatively more lamellae (up to 26; Wannathes et al. 2009). Omphalotaceae Bresinsky The family Omphalotaceae was proposed by Bresinsky in Kämmerer et al. (1985) to accommodate the genera Omphalotus Fayod and Lampteromyces Singer. The members of the family are characterized by fleshy, brightly coloured and often luminescent basidiomes with a glabrous or fibrillose pileus, decurrent lamellae, central or eccentric stipe devoid of any veil, hyaline, smooth, globose or ellipsoid and inamyloid basidiospores, clavate basidia often intergrading with cystidioles, the absence of cystidia and monomitic hyphal system with clamp connections (Cannon and Kirk 2007). Species of Omphalotaceae are saprobic or necrotrophic on wood or litter (Moncalvo et al. 2002). Moncalvo et al. (2002), in their broad systematic treatment of the euagarics using LSU sequence, observed that several genera that were traditionally classified in various families or tribes of Agaricales (Singer 1986) and Caripia montagnei, a reduced form that was generally placed in the Stereales (Hawksworth et al. 1995) were clustered together in Omphalotaceae clade together with lentinuloid and omphalotoid species. In their overview of phylogeny of Fungal Diversity Fig. 135 Consensus phylogram (50% majority rule) obtained from MCMC analysis of one million generations from a Bayesian inference analysis based on ITS region for Marasmius taxa and two outgroup sequences (Crinipellis brunneipurpurea and C. malesiana).

The newly generated previously described type specimen sequence of Marasmius midnapurensis and the sequences of the newly described taxa for the present study are placed in blue font to highlight its phylogenetic position in the tree. Ex-type strains are in bold. GenBank accession numbers for all of the sequences are indicated in the tree Marasmiellus is a predominantly tropical and subtropical genus that encompasses more than 400 species known worldwide (Wilson and Desjardin 2005; Blanco-Dios 2015). Traditionally, the genus had been placed in family Tricholomataceae (Singer 1986). While Kirk et al. (2008) treated it in the Marasmiaceae, DNA-based molecular phylogenetic studies of Moncalvo et al. (2002) and Wilson and Desjardin (2005) indicated that this genus belongs to the Omphalotaceae. Marasmiellus is characterized by collybioid, omphalioid or pleurotoid basidiomes, slightly decurrent, intervenose lamellae, smooth, white or off-white and inamyloid basidiospores, and pileipellis or stipipellis showing a Rameales-structure (Singer 1973; Pérez-DeGregorio et al. 2011). Most of the species are saprobes occurring on dead and rotting plant material and some are host specific. A few species are found on living hosts. According to Wilson and Desjardin (2005), the genus is polyphyletic. In the course of our studies on the agarics of Kerala State, India, we came across a remarkable species of Marasmiellus. It is formally described here as a new 123 Fungal Diversity Fig. 137 Marasmius indojasminodorus (CAL 1514, holotype). a Basidiomes. b Basidiospores. c Basidioles. d Siccus-type cheilocystidia. e Siccus-type cells of the pileipellis. f Caulocystidia showing setulose and nonsetulose cells. Scale bars a = 5 mm, b–f = 5 lm. Drawings by A.K. Dutta species based on both morphology and molecular phylogeny (Fig. 138). Marasmiellus bicoloripes K.P.D. Latha, K.N.A Raj & Manim., sp. nov. MycoBank number: MB820689; Facesoffungi number: FoF03251, Figs. 139, 140 Etymology: Referring to the bicoloured stipe of the basidiomes. Holotype: CAL 1524. Colour codes follow: Methuen handbook of colour (Kornerup and Wanscher 1978) and the Online Auction Color Chart (Anonymous 2004). Basidiomes small, somewhat omphalinoid. Pileus 5–20 mm diam., initially convex, becoming plano-convex with a small umbo surrounded by a shallow depression at 123 maturity; surface brown (6F4/OAC733) all over when young, becoming greyish brown (6D3/OAC730) at the centre and brownish beige (6E3/OAC723) towards the margin, not hygrophanous, faintly pellucid-striate, appressed-fibrillose all over; margin decurved to somewhat straight, initially entire, becoming somewhat wavy. Lamellae adnate or subdecurrent, somewhat thick and waxy, often furcate and anastomosing, close, brownish orange (6E2/OAC724), up to 2 mm wide, with lamellulae of 2–3 tiers; edge finely torn, concolorous with the sides. Stipe 12–14 9 1–2 mm, central, terete, equal or slightly tapering towards the base, solid; surface initially white all over, becoming dark grey (5E1, 5F1/OAC904) towards the base at maturity, appressed-fibrillose all over. Odour and taste not distinctive. Lamellar trama subregular, hyphae 3–9 lm wide, hyaline, thin-walled, inamyloid. Subhymenium poorly developed Fungal Diversity pseudoparenchymatous. Basidia 20–31 9 4–6 lm, clavate or occasionally pedicellate clavate, hyaline, thin-walled, 4or 2-spored; sterigmata up to 5 lm long. Basidiospores 4–8 9 3–4(–5) (6.5 ± 1.5 9 3.5 ± 0.6) lm, Q = 1.3–2.7, Qm = 1.9, oblong-ellipsoid, pip-shaped or subfusiform, often with a stretched-out apicular end, with prominent guttules, hyaline, inamyloid, smooth, thin-walled. Lamellar edge heterogeneous. Pleurocystidia absent. Cheilocystidia 20–32 9 4–8 lm, scarce, scattered, versiform: clavate with short or long, apical diverticulate projections or with a mucronate apex, cylindrical with a mucronate apex, utriform with a rostrate apex or flexuous, thin-walled, hyaline. Pileus trama interwoven; hyphae 3–10 lm wide, hyaline, thinwalled, inamyloid. Pileipellis a differentiated cutis with occasional nodulose-diverticulate hyphae; hyphae 3–18 lm wide, with a yellowish brown plasmatic pigment and strong, yellowish brown spiral encrustions, thin- to slightly thickwalled. Stipitipellis an epicutis; hyphae 3–6 lm wide, hyaline or with a yellowish brown plasmatic pigment, thickwalled (up to 1 lm thick), often giving rise to short or long, sometimes diverticulate side branches, 17–108 9 3–5 lm, slightly thick-walled towards the base. Caulocystidia absent. Clamp connections observed on all hyphae. Material examined: INDIA, Kerala State, Ernakulam District, Pooyamkutty, 22 November 2014, K.P.D. Latha, DKP331 (CAL 1524, holotype). Host and habitat: In small group among on a decaying twig. GenBank numbers: ITS = KY807129, LSU = KY817233. Notes: Marasmiellus bicoloripes is characterised by omphalinoid basidiomes with a greyish brown, faintly striate and fibrillose pileus, brownish orange, anastomosing and somewhat thick and waxy lamellae, a white stipe turning dark grey towards the base, oblong-ellipsoid to subfusiform basidiospores, a hymenium devoid of pleurocystidia, a heterogeneous lamellar edge with scattered cheilocystidia, a cutis-type pileipellis with occasional nodulose-diverticulate hyphae, an epicutis-type stipitipellis with frequent nodulose-diverticulate hyphae and presence of clamp connections. Owing to the combination of characteristics such as the stipe tending to greyish at the base, the cutis-type pileipellis with occasional diverticulate hyphae and the short basidiospores (less than 10.4 lm), this species can be placed either in sect. Candidi (Bat.) Sing. or in sect. Dealbati Sing. (Singer 1986) of Marasmiellus. Marasmiellus cibodasensis Retnowati, an Indonesian species described invalidly by Retnowati (2012), differs in having a flattened pileus with a wrinkled surface, subdistant, non-anastomosing lamellae, an apically tapered, granulose and bulbous stipe which is not darkening towards the base, ellipsoid basidiospores, a fertile lamellar edge devoid of cheilocystidia and a gregarious habit on wood. Marasmiellus rhizomorphigenus Antonı́n et al., known from Republic of Korea (Antonı́n et al. 2010), differs in having a greyish to whitish pileus with a pubescent to tomentose surface, whitish to pale yellowish and distant lamellae, a stipe with a pubescent to furfuraceous surface, presence of rhizomorph, larger basidiospores (13.5–17 9 4.5–6.5 lm), well-developed, larger hymenial cystidia (34–70 9 8–14 lm) and presence of pileo- and caulocystidia. Marasmiellus koreanus Antonı́n et al. also described from Republic of Korea (Antonı́n et al. 2010), has larger, robust basidiomes with a brownish orange, rugulose pileus, light yellow lamellae, whitish to light yellow stipe, versiform cheilocystidia and stipitipellis with copious caulocystidia. Marasmiellus candidus (Fr.) Singer, a widespread species in Europe (Noordeloos 1995), differs in having a pure white, pruinose to tomentose pileus with a greybrown centre, a pruinose stipe with a bulbous base, oblong to cylindrical and larger basidiospores [(10.5–)11.5–15(– 17.5) 9 (7.5–)8.0–12.5 lm], copious and larger cheilocystidia (45–90 9 6–12.5 lm), an irregular cutis-type pileipellis with a transition to a trichoderm and the stipitipellis with caulocystidia. The phylogenetic trees inferred from the ML and BI analyses of the ITS sequence dataset show identical topology and the ML phylogram is presented in Fig. 138. The tree reveals two distinct clades, the Tetrapyrgos and the Marasmiellus clades, as shown by Wilson and Desjardin (2005) and subsequently confirmed by Antonı́n et al. (2010). Marasmiellus bicoloripes nests in the Tetrapyrgos clade with 82% ML and 1.00 BYPP support. Within this clade, M. bicoloripes together with collections of M. rhizomorphigenus, M. tenerrimus (Berk. & M.A. Curtis) Singer and M. candidus formed a cluster where M. bicoloripes was found to be a lineage distinct from other species with significant support (73% ML and 1.00 BYPP). It has to be emphasized here that the clade Tetrapyrgos does not exactly correspond to the genus Tetrapyrgos as the latter is primarily characterised by tetrahedral basidiospores and a stipe arising from a basal pad (Honan et al. 2015) while some species including M. bicoloripes and M. candidus that form part of the clade Tetrapyrgos do not show these features. Psathyrellaceae Vilgalys et al. Based on molecular studies, Redhead et al. (2001) introduced the family Psathyrellaceae to accommodate the genera Psathyrella (Fr.) Quél. and Lacrymaria Pat., together with related species in the polyphyletic genus Coprinus sensu lato, which were transferred to the genera Coprinellus P. Karst., Coprinopsis P. Karst. or Parasola Redhead et al. A few species related to Agaricus remained in Coprinus sensu stricto. Therefore, the concept of family Coprinaceae Overeem & Weese was abandoned and 123 Fungal Diversity Coprinus sensu stricto was transferred to Agaricaceae Chevall. Afterwards, several smaller genera were included in Psathyrellaceae. Kirk et al. (2008) consider the family to contain 12 genera. Coprinopsis P. Karst. Coprinopsis is a large genus that contains around 200 species (Kirk et al. 2008). They are saprotrophic on soil, wood, vegetable refuse, dung or burnt ground, and produce agaricoid, rather fragile basidiomes which are often short lived and/or deliquescent, with black to blackish spore deposit (Vesterholt 2012). The phylogenetic tree is presented in Fig. 141. Coprinopsis kubickae (Pilát & Svrček) Redhead, Vilgalys & Moncalvo, in Redhead et al., Taxon 50(1): 229 (2001) Facesoffungi number: FoF05721, Fig. 142 Basionym: Coprinus kubickae Pilát & Svrček, Česká Mykol. 21: 142 (1967). Holotype: Czechoslovakia, on culm of Juncus. Pileus up to 10 mm wide when expanded, sphaerical at first, then ellipsoid to ovoid, paraboloid, convex, finally applanate or plano-concave with revolute margin, plicatesulcate except at the centre, whitish to pale brown when young, then pinkish, finally brownish grey except brownish central disc, non-deliquescent, covered with scarce, minute, brownish to brown flocculose veil. Lamellae free, distant, L = 22–34, l = 1–3, white at first, becoming pinkish, then reddish brown with whitish and flocculose edge, finally brown-black and deliquescent. Stipe 16–28 9 0.8–1.2 mm, cylindrical or gradually thickened towards the base, which is often (sub) bulbose or with basal disc (up to 2 mm wide), central, hollow, dry, minutely fibrillose-floccose, often tomentose at the base, white. Odour and taste not observed. Spore print brown-black. Basidia 14–31 9 9–12 lm, clavate, 4-spored, thin-walled, hyaline, surrounded by 5–8 hymenophysalides (pseudoparaphyses). Basidiospores [100/2/1] 8–9.6–11.1 9 6.9–8.2– 9.3 lm, Q = (1–)1.05–1.17–1.30(–1.38), mostly subglobose, broadly ellipsoid or ovoid, but also globose and ellipsoid, not flattened, with rounded to slightly conical base and rounded apex, smooth, thin-walled to moderately thick-walled (up to 0.7 lm), with 1.2–1.8 lm wide (inner diameter), central to eccentric germ-pore, medium rusty brown in H2O and NH4OH, medium brown in KOH, but soon becoming medium brown grey, semi-transparent, non-amyloid and non-dextrinoid. Cheilocystidia 30–90 9 9–24 lm, narrowly utriform to utriform, oblong, subcylindrical, conical or narrowly clavate, thin-walled to moderately thick-walled (up to 0.7 lm), hyaline, scattered. Pleurocystidia 50–110 9 13–24 lm, similar to cheilocystidia, but somewhat more elongated, mostly narrowly utriform, narrowly conical or subcylindrical, scattered. Veil composed of 2–6 lm broad, branched, thin-walled, rather 123 sparsely diverticulate, hyaline to light yellowish brown hyphae, mostly with minutely to coarsely encrusted, light to dark brown pigment. Pileipellis a cutis, composed of repent, hyaline, thin-walled, 1.5–5 lm wide hyphae. Stipitipellis a cutis of parallel, repent, thin-walled, hyaline, 1–8 lm wide hyphae, sparsely diverticulate, with ascending hyphal tufts in places. Clamp connections present and abundant in all tissues. Material examined: CROATIA, Karlovac County, Fishpond Draganići, 10 km NE from Karlovac, 45°330 4000 N, 15°380 2100 E, 107 m a.s.l., 7 September 2013, leg. M. Čerkez, CNF 1/6614. Host and habitat: Solitary or in small groups on dead Phragmites, Typha, Juncus, Carex, Glyceria and Acorus species in wet habitats, as well as on rich soil and rotten straw in greenhouses (Uljé 2005; Nagy 2007; Gierczyk et al. 2011). From Canada reported on wood submerged in an alkali lake (Anastasiou 1967; as Coprinus amphibius Anastasiou). Our collection was collected on wet remnants of Phragmites australis, on the marshy edge of a fishpond. Distribution: Known from about 15 European countries and Canada, rare. GenBank number: ITS = MH422562. Notes: Coprinopsis kubickae is primarily characterized by its branched, diverticulate and thin-walled veil elements, presence of clamp connections, smooth, globose to broadly ellipsoid, not flattened spores, rather small basidiomes and by living on plant (almost always herbaceous) remnants in wet habitats. Morphologically (according to branched and diverticulate veil), it belongs to section Alachuani (Singer) D.J. Schafer. However, the morphological concept of section Alachuani is not supported by molecular data and several Alachuani species are mixed with species of sections Atramentarii (Fr.) D.J. Schafer and Lanatuli (Fr.) D.J. Schafer in our ITS based phylogram (Fig. 141). Still, Coprinopsis kubickae nests in the clade with the rest of Alachuani species. We report Coprinopsis kubickae as new to Croatian mycobiota. Boletales E.-J. Gilbert Boletaceae Chevall. Boletaceae is an important Basidiomycete family with a global distribution, most of which form ectomycorrhizal associations with trees. Most species have been described from temperate regions, and little research had been carried out on tropical boletes before 2010. In the past decade, however, phylogenetic analyses based on multigene dataset and including tropical taxa, have greatly improved our understanding of the systematics of the group, with many new genera and species being published (e.g., Halling et al. 2012; Hosen et al. 2013; Wu et al. 2015, 2016; Henkel et al. 2016). This molecular revolution has left a number of Boletaceae species (especially in the large genus Boletus) Fungal Diversity Fig. 138 Phylogram derived from maximum likelihood (RAxML) analysis using ITS sequence dataset. Maximum likelihood (RAxML) bootstrap support (left) C 50% and Bayesian posterior probabilities (right) C 0.90 BYPP are indicated above the nodes. Marasmiellus bicoloripes is highlighted in blue. Marasmius rotula and M. capillaris are selected as the outgroup taxa to be re-examined and recombined in the light of modern classification of the family. A novel species, Baorangia major is introduced based on distinct morphological characteristics coupled with phylogenetic analysis of a combined ATP6, RPB2, and TEF1-a dataset (Fig. 143). Two new combinations, Baorangia rufomaculata and Lanmaoa pallidorosea are also designated in this study. Baorangia G. Wu & Zhu L. Yang Baorangia was first recognized by Wu et al. (2014, as ‘clade 51’), and later formally described by Wu et al. (2015). Typical characteristics are a thin hymenophore that is 3–5 times thinner than the pileus context, yellow tubes and pores that stain blue when bruised, a light yellow context that slowly stains pale blue when cut, and a 123 Fungal Diversity Fig. 139 Marasmiellus bicoloripes (CAL 1524, holotype). a, b Basidiomes in the field.

Habit and habitat: Mostly gregarious, sometimes fasciculate or solitary, on soil in forests dominated by Lithocarpus spp., Castanopsis spp., sometimes mixed with Dipterocarpus spp. Distribution: Known from Chiang Mai Province, Thailand and Yunnan Province, China. GenBank numbers: ATP6 = MG897421, RPB2 = MG897441, TEF1-a = MG897431 (OR209, holotype); ATP6 = MG897422, RPB2 = MG897442, TEF1a = MG897432 (OR404), ATP6 = MG897423, RPB2 = MG897443, TEF1-a = MG897433 (OR486). Notes: Baorangia major can easily be recognised in the field by its large basidiomes when mature, decurrent hymenophore with large, angular, radially arranged (at least near the stipe), and 1–3 times compound pores, red stipe that immediately and intensely turns blue when injured or merely touched. In their diagnosis of Baorangia, Wu et al. (2015) mentioned ‘‘context which stains pale blue slowly when cut’’. While this fits B. major pileus context, it does not fit its stipe context, which quickly and intensely stains blue when cut. Baorangia bicolor (Kuntze) G. Wu et al. and B. rufomaculata (see below) somewhat resembles 123 B. major, but the latter can easily be distinguished by the large angular pores and intense blueing.

Both 4144 (CFMR). Distribution: North America. GenBank numbers: ATP6 = MG897415, RPB2= MG897435, TEF1-a = MG897425. Notes: The specimen we studied (Both 4144) was already sequenced by Nuhn et al. (2013) for LSU, RPB1, and TEF1-a genes, but under the wrong number ‘‘4414’’. Our TEF1-a sequence is 100% identical to the one published by Nuhn et al. (2013), except for the insertion of an ‘‘N’’ at position 215 in the latter, which is likely an artefact. Our measurements of microscopic characteristics slightly deviate from the original description of Both (1998). However, the specimen we studied was collected and identified by Both from the type locality. Therefore, we are confident that it belongs to the same species. Lanmaoa G. Wu & Zhu L. Yang The genus Lanmaoa was recognized by Wu et al. (2014, as ‘clade 49’), and later formally described by Wu et al. (2015). The typical characteristics of the genus are a thin hymenophore which is 3–5 times thinner than the pileus context and stains blue when bruised, a light yellow context that slowly stains pale blue when cut, and an interwoven trichodermium to subcutis pileipellis (Wu et al. 2015). Seven species are recorded in the genus, L. angustispora G. Wu & Zhu L. Yang, L. asiatica G. Wu & Zhu L. Yang (generic type), L. carminipes (A.H. Sm. & Thiers) G.

Notes: Although the specimen we examined is immature and we could not check basidiospore and basidia dimensions, we are confident that it belongs to the species described by Both (1998). Indeed, it was collected and identified by E. Both himself from the type locality. Cantharellales Gäum. Clavulinaceae Donk Clavulinaceae was established by Donk (1933) as a tribe, but later Donk (1961) raised the tribe to the rank of family. The family Clavulinaceae comprises four genera, Burgella Diederich & Lawrey, Clavulina J. Schröt., Membranomyces Jülich and Multiclavula R.H. Petersen (Kirk et al. 2008).

A novel species, Clavulina thindii is introduced based on distinct morphology and maximum likelihood phylogeny of ITS sequence data (Fig. 148). Clavulina J. Schröt. Clavulina is distributed worldwide and characterized by clavarioid to coralloid, occasionally resupinate and effused, 123 simple or branched basidiomes, monomitic hyphal system, with clamp connections in most species; smooth, hyaline, subglobose to broadly ellipsoid basidiospores usually with one large guttule; basidia with two or up to six cornuted sterigmata and often develop a transversal septum (Corner 1950, 1970; Petersen 1988a; Henkel et al. 2005, 2011; Uehling et al. 2012a; He et al. 2016). Species of Clavulina Fungal Diversity occur in forests dominated by ectomycorrhizal (ECM) trees of the leguminous genera (Fabaceae) (Henkel et al. 2011). Approximately 82 species have been described in the genus Clavulina (Corner 1950, 1970; Thind 1961; Petersen 1967, 1983, 1985, 1988a, b; Thind and Sharda 1984; Roberts 1999; Thacker and Henkel 2004; Henkel et al. 2005, 2011; Douanla-Meli 2007; Duhem and Buyck 2007; Trappe and Castellano 2007; Olariaga and Salcedo 2012; Uehling et al. 2012a, b; Wartchow 2012; He et al. 2016). Clavulina thindii U. Singh, sp. nov. MycoBank number: MB824527; Facesoffungi number: FoF04878, Figs. 149, 150 Etymology: To commemorate Prof. K.S. Thind for his contribution to Indian mycobiota. Holotype: CAL 1661 Colour codes follow: Methuen handbook of colour (Kornerup and Wanscher 1978). Basidiomes 41–66 9 30–49 mm, coralloid, terrestrial, profusely branched, solitary to scattered; sterile stipe 12–28 9 7–12 mm, white to greyish white, glabrous; fertile branches 30–38 9 2.5–4.5 mm, forming 4–7 ranks in multiple planes, branching pattern polychotomous to dichotomous-ascending, initially violet white to pale violet (16A2–3), maturing to lilac grey to lilac (16B2–3), wax white to greyish yellow (2B3–4) with drying, smooth; hymenium ripening over distal two-thirds of basidiomes, amphigenous, interface with stipe clearly demarcated; apices roundedacuminate to irregularly coronate or blunt, concolorous with branches when young, becoming brownish orange (6C8) at maturity; context subsolid to hollow, concolorous with branches. Taste and Odour pleasant. Basidiospore deposit not obtained. Basidia 22–48 9 6–10 lm, subcylindrical to subclavate or clavate, with numerous granular contents, postpartial septa observed on some basidia, basally clamped, 2-spored; sterigmata up to 7 lm long, cornuted; basidioles numerous, subcylindrical to clavate. Hymenophoral tramal hyphae sub-regular to irregular; noninflated tramal hyphae 5–8 lm, smooth, thin-walled, hyaline, lacking internal contents; inflated tramal hyphae 11–15 lm, smooth, thin-walled, hyaline, lacking internal contents. Cystidia absent. Basidiospores 6.5–7.5–8 9 6–6.4–7 lm (n = 30, Q = 1.07–1.15– 1.25), subglobose to broadly ellipsoid, smooth, pale yellow in KOH, inamyloid, with one translucent guttule; apicules up to 1 lm long. Clamp connections present. Material examined: INDIA, Uttarakhand, Pauri Garhwal District, Gangoti-Adwani forest, alt. 1948 m, N 30°05.7990 E 078°43.9270 , 3 October 2016, U. Singh, US 1428 (CAL 1661, holotype); ibid., 31 August 2017, U. Singh, US 1585. Host and habitat: Solitary to scattered, on ground, under trees of Acacia dealbata A. Cunn. in mixed temperate forest. Distribution: Known only from India. GenBank numbers: ITS = MG892054 (US 1428); ITS = MG892055 (US 1585). Notes: Clavulina thindii is distinct from all other species of Clavulina by the ITS sequence data and combination of morphological features: violet to lilac profusely branched basidiomes (42–66 9 38–49 mm) with white to greyish white stipe and rounded-acuminate to irregularly coronate or blunt apices, subsolid to hollow context, subglobose to broadly ellipsoid basidiospores, cylindrical to subclavate basidia with two cornuted sterigmata, absence of cystidia, noninflated to inflated tramal hyphae and presence of clamp connections. In field, Clavulina thindii may appear similar to C. livida Shu Z. Yan et al. with both species possessing large sized, branched basidiomes with rounded-acuminate apices which turn brown at maturity, smooth basidiospores with one large guttule, subcylindrical to clavate basidia with sometimes post-partial septa, absence of cystidia, noninflated to inflated tramal hyphae and presence of clamp connections. However, the latter has greyish basidiomes with olive stipe, larger (11.6–12.9 9 10.7–12.5 lm), globose to subglobose basidiospores and larger basidia (51.5–76.5 9 7–12.3 lm) (He et al. 2016). Clavulina amethystina (Bull.) Donk shares similarities with C. thindii in having lilac to violet, branched basidiomes with obtuse to blunt apices, but the former has completely lilac to violet basidiomes (the stipe of Clavulina thindii is white to greyish white), becoming dark grey with age and ellipsoid (Lm/Wm & 1.55–1.62) basidiospores (Corner 1950; Olariaga et al. 2009). Clavulina cinerea (Bull.) J. Schröt, C. rugosa (Bull.) J. Schröt, C. coralloides (L.) Schröt. (= C. cristata), C. subrugosa (Cleland) Corner and C. samuelsi R.H. Petersen are also closely related to C. thindii. However, these five species show morphological differences from C. thindii. Clavulina cinerea differs from C. thindii by its white to dark grey basidiomes with acute to blunt apices, indistinct or not well-delimited stipe due to basitonic branching and ovoid (Lm/Wm = 1.1–1.3) basidiospores (Bulliard 1788; Olariaga et al. 2009). Clavulina rugosa is distinguished by its simple to sparsely branched, white basidiomes, noncristate and normally obtuse apices and relatively larger basidiospores (9–14 9 8–12 lm, Lm 9 Wm = 9.9–10.6 9 8.2–8.8) (Corner 1950; Olariaga et al. 2009). Clavulina coralloides differs from C. thindii by its white to grey basidiomes with not well-delimited stipe due to basitonic branching, cristate apices, comparatively larger and subglobose basidiospores (7–11 9 6.5–10 lm) (Holmskjold 1790; Corner 1950; Olariaga et al. 2009). Clavulina subrugosa can be separated from C. thindii by its simple or filiform to flattened branched, white to pale greyish brown basidiomes and rather large basidiospores (6.8–8.6 9 5.8–7.2 lm) (Corner 1950; Petersen 1988a). 123 Fungal Diversity Fig. 146 Baorangia rufomaculata microscopic features. a Basidiospores. b Basidia. c Cheilocystidia. d Pleurocystidia. e Caulocystidia. f Pileipellis. g Stipitipellis.

(an Indian species) shares similarities with C. thindii in possessing profusely branched basidiomes and sometimes subglobose basidiospores but the former has cream-white to greyish brown basidiomes with cristate to acute apices and larger Fungal Diversity Fig. 147 Lanmaoa pallidorosea microscopic features. a Cheilocystidia. b Pleurocystidia. c Two types of caulocystidia. d Pileipellis. e Stipitipellis. Scale bars a–c = 20 lm, d, e = 50 lm. All drawings were made from Both 4432 basidiospores (7–9 9 5.6–8 lm) (Corner et al. 1958). Clavulina limosa K.S. Thind & Sharda (also originally reported from India) differs from C. thindii by simple (unbranched), slimy, creamish white to pallid-cream basidiomes and globose to subglobose basidiospores (Thind and Sharda 1984). Thind (1961) reported Clavulina amethystinoides (Peck) Corner from India, but the conspecificity has not yet been verified with help of sequence data from the Indian collections. Clavulina amethystinoides shares some similarities with C. thindii in possessing violet basidiomes and 2-spored basidia, but differs in having simple or sparsely 123 Fungal Diversity branched basidiomes, comparatively larger and globose to subglobose basidiospores (9–12.3 9 8.8–10.5 lm). Moreover, C. amethystinoides (originally reported from USA) differs from C. thindii by having simple or irregular branches, slightly palmate branching, pale drab, pinkish tan, fawn or very pale lilac basidiomes, pale livid flesh, eventually blackening tips with distinctly different colour and larger basidiospores (7–10 9 6–8 lm) (Corner 1950). Clavulina thindii is commonly collected and consumed by local villagers. ‘Angalchyun’ (fingers like mushroom) is the vernacular name used for this species in the local language (Garhwali). However, inhabitants refer this vernacular name (Angalchyun) for all clavarioid fungi. The ITS dataset consisting of 49 sequences (including our isolates: US 1428, represented by GenBank no. MG892054 and US 1585, represented by GenBank no. MG892055) of Clavulina and Hydnum L. was analyzed by maximum likelihood phylogenetic inference (Fig. 148). Two sequences isolated from Indian materials appear to be nested amongst other sequences of Clavulina and form a distinct clade being sister to Chinese collections of C. livida (represented by KU219603, KU219604, KU219605 and KU219606). The combination of morphological features and phylogenetic analysis indicates that Clavulina thindii is a new species, distinct from all the known taxa of Clavulina. Polyporales Gäum. Phanerochaetaceae Jülich The family Phanerochaetaceae was described by Jülich (1981) with Phanerochaete as generic type, and also including the genera Meruliopsis Bondartsev, Phlebiopsis Jülich and Scopuloides (Massee) Höhn. & Litsch. This family was characterized by mostly resupinate basidiome, thick-walled hyphae, often without clamps, basidia narrowly clavate and spores hyaline, smooth and thin-walled (Larsson 2007; Ryvarden and Melo 2014; Yuan et al. 2017). Justo et al. (2017) revised the family on the basis of molecular and morphological data and, in addition to Phanerochaete, they include the following thirteen genera: Bjerkandera P. Karst., Donkia Pilát, Hapalopilus P. Karst., Hyphodermella J. Erikss. & Ryvarden, Oxychaete Miettinen, Phaeophlebiopsis Floudas & Hibbett, Phanerina Miettinen, Phlebiopsis Jülich, Pirex Hjortstam & Ryvarden, Porostereum Pilát, Rhizochaete Gresl. et al., Riopa D.A. Reid and Terana Adans. Most of these genera are corticioid and rarely polyporoid, with the hyphal system monomitic or sometimes dimitic, and most have hyphae without clamps; cystidia are often present and spores are thin-walled, hyaline and smooth. All species of this family produce a white-rot. Phanerochaete P. Karst. 123 Phanerochaete is a genus of widespread corticioid fungi that causes white rot on all kinds of decayed wood and plays a key role in forest ecosystems. The genus contains 167 legitimate names (MycoBank 2019). Since 2008 eight new species and one subspecies have been described (Nakasone 2008; Ghobad-Nejhad et al. 2015; Floudas and Hibbett 2015; Liu and He 2016; Sádlı́ková and Kout 2017; Spirin et al. 2017), and six new combinations have been proposed (Nakasone 2008; Hjortstam et al. 2009; Melo et al. 2012; Floudas and Hibbett 2015; Volobuev et al. 2015; Miettinen et al. 2016). Phanerochaete was described by Karsten (1889) to accommodate Thelephora alnea Fr. and T. odora Fr., and therefore based on two elements, without designation of a type. Cooke (1953) considered T. alnea as generic type and later Corticium decolorans (= Phanerochaete velutina) was chosen as lectotype by Eriksson et al. (1978a). Recently, Spirin et al. (2017) reinstated T. alnea as the generic type. Long neglected, Phanerochaete was reintroduced by Donk (1957) with the two initial species. Several years later, the taxonomy of the genus was discussed by Donk (1962), Parmasto (1968), Eriksson et al. (1978b) and Burdsall (1985). Donk (1962) amended Phanerochaete, recognizing that the generic limits were uncertain and suggesting that other taxa should be included. Parmasto (1968) accepted twenty species separated in two subgenera, Phanerochaete and Phanericium Parm.; cystidiate and acystidiate species, respectively. Eriksson et al. (1978b) recognized twelve species in Northern Europe divided into three groups, Phanerochaete velutina group (= subgen. Phanerochaete), P. tuberculata group (= subgen. Phanericium Parm.), and P. septocystidiata group, the last one with only one species characterized by cystidia regularly septate. Burdsall (1985) recognized 42 species in three subgenera, Phanerochaete, Phanericium, and Scopuloides (Massee) Burdsall, the latter with cystidia and subiculum usually distinct. Phylogenetic studies carried out in Phanerochaete sensu Burdsall (1985) showed that the genus is polyphyletic (De Koker et al. 2003; Wu et al. 2010a) and its species are distributed in nine phylogenetic linages across the phlebioid clade within order Polyporales (Floudas and Hibbett 2015). According to Floudas and Hibbett (2015) one of these linages, Phanerochaete sensu stricto, includes species mostly found in the subgenus Phanerochaete sensu Burdsall (1985). From a morphological point of view, the species included in the Phanerochaete sensu stricto clade in Floudas and Hibbett (2015) and in our LSU analysis (Figs. 151, 152) are characterized by their basidiomes being resupinate, membraceous, white, yellowish orange, or red to brown; the subiculum well-developed and the margin mostly fibrillose, with or without cordons. The hyphal Fungal Diversity Fig. 148 Maximum likelihood phylogeny of Clavulina showing the position of novel species Clavulina thindii (shown in blue and bold). The ITS sequence dataset was aligned with online version of MAFFT v. 7 (Katoh and Standley 2013) and no manual editing was done within the alignment. One-thousand bootstrap replicates were analyzed to obtain nodal support values. Analysis was conducted with MEGA 6.0 (Tamura et al. 2013).

(2016); the new species, Phanerochaete australosanguinea is introduced. Phanerochaete australosanguinea Telleria, M. Dueñas & M.P. Martı́n, sp. nov. MycoBank number: MB825276; Facesoffungi: FoF05725, Figs. 153, 154 Etymology: From Latin ‘‘australis’’ which means southern and ‘‘sanguinea’’ refers to the morphological similarity of this species with Phanerochaete sanguinea (Fr.) Pouzar Holotype: 20102Tell, MA-Fungi 91309 Colour codes follow: ISCC-NBS Centroid Colour Charts (Kelly and Judd 1976) Basidiomes resupinate, orbicular to confluent, membranaceous, closely adnate; hymenophore smooth to slightly cracked in mature specimens; brownish orange (54. Br O–37. m r O) when young, in mature specimens orange yellow (70. l. OY–71. m. OY); the edge especially differentiated by dark reddish orange (38. d. r O). Margin fibrillose and white; with well-developed dark strands sometimes present. KOH 3% reaction (?) turning green that quickly change to brown. Subiculum byssoid, white to cream, lighter in colour than the hymenophore. Hyphal system monomitic. Subicular hyphae thick-walled, loosely interwoven, sparsely branched, growing parallel to the substrate, (5–)8–10 lm wide, sometimes with orange brown content, with single clamps. Subhymenial hyphae thin-walled and short-celled, branched, densely interwoven, growing perpendicular to the substrate, 3–5 lm wide. Cystidia thin-walled, cylindrical to tapering, sometimes with secondary septa, 44–66 9 4–5 lm. Basidia narrowly cylindrical to claviform, four sterigmata, 40–46 9 4–5 lm. Spores ellipsoid, 4.5–5.5 9 3–3.5 lm, thin-walled, sometimes with oil drops in the protoplasm, Q (L/W) = 1.29. Material examined: CHILE, Los Lagos, Palena, Hornopirén, comuna Hualainhué, Huinay Biological Reserve, path to Cerro del Tambor, 42°220 5400 S 72°240 5300 W, 202 msl, on unidentified wood, 8 May 2013, M. Dueñas, M.P. Martı́n & M.T. Telleria, 20102Tell., (MA-Fungi 91309, holotype); ibid., 20098Tell. (MA-Fungi 91308); 20114Tell. (MA-Fungi 91310). Host and habitat: Known from the Valdivian temperate rain forest, Chilean Patagonia, South America, growing on decayed wood and associated with white rot. GenBank numbers: ITS = MH233925, LSU = MH233928 (20098Tell., MA-Fungi 91308); ITS = MH233926, LSU = MH233929, (20102Tell., MA-Fungi 91309, holotype); ITS = MH233927 (20114Tell., MA-Fungi 91310). Notes: Based on LSU analyses (Fig. 151), Phanerochaete australosanguinea clusters into the Phanerochaete sensu stricto clade in the P. sanguinea complex, according to the maximum likelihood phylogeny of the concatenated ITS, LSU, RPB1 and RPB2 obtained by Floudas and Hibbett (2015). Most species of this complex cause red–orange staining of the substrate, such as P. australosanguinea (Fig. 153c). In the LSU analyses, P. australosanguinea is a sister species of P. sanguineocarnosa Floudas & Hibbett. Morphologically, this is corroborated by both species sharing well-developed dark strands, the KOH reaction turning quickly green changing to brown on the basidiome; the subicular hyphae having developed clamps, and cystidia in both species are cylindrical, tapering to the apex, with secondary septa and of similar size. However, the spores are ellipsoid to broadly ellipsoid in P. australosanguinea (Q = 1.29), while those of P. sanguineocarnosa, described by Floudas and Hibbett (2015), are sub-ellipsoid to ellipsoid (Q = 1.8). In the ITS analyses (Fig. 152), Phanerochaete australosanguinea also clusters in the P. sanguinea complex. However, the newly generated sequences are very distinct 123 Fungal Diversity from those of the P. sanguinea complex of Floudas and Hibbett (2015). These authors included mainly species and specimens from the Northern hemisphere (except one sequence from Tasmania). The three collections from Chile form a basal and highly supported group (99% ML, 97% MP and 1.00 PP) indicating that P. australosanguinea is distinct from other species of the P. sanguinea complex by its geographical distribution. So far, P. australosanguinea has been reported from Valdivian temperate rain forest in Chilean Patagonia, where it is probably frequent and could have been confused with P. sanguinea (Fr.) Pouzar reported from the Patagonian Andes forest of Southern Argentina by Greslebin and Rajchenberg (2003). Russulales Kreisel ex P.M. Kirk et al. Russulaceae Lotsy Russulaceae is one of the most speciose, and morphologically diverse ectomycorrhizal mushroom families (Miller et al. 2006; Hyde et al. 2016). This family has a worldwide distribution of more than 1200 species (Kirk et al. 2008). Multigene molecular phylogenetic analyses consistently recovered this family as a monophyletic clade which is now comprised of four genera: Russula Pers., Lactarius Pers., Lactifluus (Pers.) Roussel and Multifurca Buyck & Hofstetter (Buyck et al. 2008, 2010). We follow the treatments and the updated accounts of taxa in Russulaceae in Li et al. (2016), Hyde et al. (2016, 2017), De Crop et al. (2017) and Tibpromma et al. (2017). Four novel species viz. Lactarius olivaceopallidus, Lactifluus midnapurensis, Russula choptae and R. uttarakhandia are introduced in Russulaceae based on morphological distinctiveness and phylogenetic support. An updated phylogenetic tree of Lactarius, Lactifluus, Russula subg. Russula and subg. Incrustatula are provided. Detailed discussion and reviewed literatures were provided in Li et al. (2016), Hyde et al. (2016, 2017), De Crop et al. (2017) and Tibpromma et al. (2017). Lactarius Pers. Lactarius is one of the most prevalent agarics which form obligate symbiotic associations with many wide spread genera of trees (Verbeken et al. 2001; Le et al. 2007; Das and Verbeken 2011; Verbeken and Nuytinck 2013; Das et al. 2015; Hyde et al. 2016; Uniyal et al. 2017). Multigene based phylogenetic studies resulted segregation of paraphyletic Lactarius sensu lato into Lactifluus Pers. (Roussel) and Lactarius (including all angiocarpic species). Lactarius sensu novo consists of three cosmopolitan subgenera: Lactarius subg. Lactarius, L. subg. Plinthogalus (Burl.) Hesler & A. H. Sm. and L. subg. Russularia (Fr. ex Burl.) Kauffman (Verbeken and Nuytinck 2013; Das et al. 2015). Recent studies indicate the high species richness within L. subg. Lactarius in the Indian Himalayan region 123 (Sharma and Das 2003; Das and Sharma 2005; Das and Verbeken 2011; Das 2013; Das et al. 2015; Uniyal et al. 2017). A novel species within L. subg. Lactarius sect. Uvidi, collected from Himalayan temperate forest (India) is presented here with morphological details and ITS phylogeny (Fig. 155). Lactarius olivaceopallidus Uniyal, sp. nov. MycoBank number: MB820694; Facesoffungi number: FoF04839, Figs. 156, 157 Etymology: Due to pale olive colour of basidiomes. Holotype: CAL 1401 Colour codes follow: Methuen Handbook of Colour (Kornerup and Wanscher 1978). Pileus 21–88 mm diam., convex, centrally depressed, finally infundibuliform, olive yellow (3C6) at centre, greyish yellow (4C4–7) toward margin, paler at margin, surface slimy to gelatinous, viscid at centre, sticky when dry, azonate to faintly zonate near margin, pale yellow (3A3) then yellow (3A7) with 30% KOH; margin decurved to inrolled. Lamellae yellowish white (1A2), pale yellow (3A2) in age, often with greyish yellow (4B4) spots, greyish violet (15D5) on bruising, adnate to broadly adnate, close (10–17 L ? l/cm), including lamellulae), some forked near stipe, lamellulae numerous. Stipe 21–45 9 10–23 mm, yellowish white (4A2) to pale yellow (4A3), spotted with light yellow (4A5) scrobiculi, stuffed to hollow. Context up to 14 mm thick in pileus, yellowish white (1A2), pale yellow (3A3) with KOH, pale yellow (3A2) in stipe, immediately turning violet (15C6) on exposure. Latex yellowish white (3A2), rather abundant, immediately turning dull lilac (15C3) on gills, context, white paper and after 2–3 minutes on glass slide. Odour pleasant. Taste acrid. Basidia 51–72 9 9.5–16 lm, subclavate, 2–4-spored, sterigmata 5–9 lm long. Basidiospores 7.5–8.7–9.5 9 7–7.7–8.5 lm, (n = 40, Q = 1.06– 1.12–1.21), subglobose to broadly ellipsoid; ornamentations amyloid, 1.7–2 lm high, mostly composed of broad ridges with wavy to even margin, triangular narrow ridges with round apices and small isolated warts, forming a dense incomplete reticulum; plage distally amyloid. Pleuromacrocystidia 51–113 9 9–17.5 lm, abundant, subclavate to fusiform, mostly round to blunt and acute apices, sometimes mucronate, contents dense. Pleuropseudocystidia up to 9 lm thick, nonemergent, cylindrical with rounded nonforked apex. Lamellae edge sterile composed of cheilomacrocystidia and marginal cells. Cheilomacrocystidia 34–63 9 8.5–12 lm, broadly fusiform, round to blunt apex. Marginal cells 13–23 9 4–6 lm, cylindric to subfusiform with rounded apex. Hymenophoral trama mainly composed of sphaerocytes and abundant lactifers, lactifers up to 14 lm wide. Pileipellis an ixocutis, 300–630 lm thick, composed of densely packed septate Fungal Diversity Fig. 151 Phylogram generated from Bayesian inference analysis of LSU sequence data of species of Phanerochaete sensu stricto from Floudas and Hibbett (2015) and the new species is marked in grey square. Maximum parsimony and maximum likelihood bootstrap support C 50% (10.000 replicates both), and Bayesian posterior probabilities C 0.50 BYPP are shown above the nodes. The tree is rooted with Pirex concentricus and Hyphodermella rosae. Newly generated sequences are in blue, types are in bold hyphae, often shriveled, forming bundles in outer parts, 1–4 lm thick. Lactifers in pilear trama up to 11 lm wide. Stipitipellis an ixocutis, 65–102 lm thick, hyphae 1–4 lm wide, septate, not shriveled. Material examined: INDIA, Uttarakhand, Pauri Garhwal, Chaubatta, alt 1904 m, N30° 09.6810 E78° 51.2220 , 19 July 2016, P. Uniyal, PU-1110 (CAL 1401, holotype); ibid., Pauri Garhwal, Chaubatta, 16 July 2016, P. Uniyal, PU 15-1090. Host and habitat: Gregarious, under Quercus leucotrichophora A. Camus in temperate mixed forest. GenBank numbers: ITS = KY440363 (CAL1401), ITS = MF741705 (PU 15-1090). Notes: Lactarius olivaceopallidus differs from other members of Lactarius sect. Uvidi due to presence of pale olive basidiomes, abundant yellowish white latex, very high (B 2 lm) ornamentations of basidiospores and very thick (B 630 lm) ixocutis type of pileipellis. The combination of characteristics like viscid to slimy, azonate to slightly zonate pileus, ixocutis pattern of pileipellis and presence of white latex turning dull lilac on exposure undoubtedly place the present taxon in Lactarius sect. Uvidi. In the field, Lactarius olivaceopallidus can easily be recognized by its pale olive basidiome, slimy to gelatinous pilear surface, pale yellow lamellae turning lilac when damaged, scrobiculate stipe surface and yellowish white latex that immediately changes into lilac on gills. Microscopically, very thick pileipellis (B 630 lm) and basidiospores with very high prominences (up to 2 lm) in form of a dense incomplete reticulum are also distinct. Studies have suggested that poor molecular resolution in Lactarius sect. Uvidi has been a problem, as species in this group are dissimilar but genetically very close (Das et al. 2015; Barge et al. 2016). Species of L. sect. Uvidi in present study are well-separated (Fig. 155) from species belonging to other sections of L. subg. Lactarius. Two collections of the present species L. olivaceopallidus (CAL1401 and PU 15-1090) are distinctly separated in a relatively long branch from its closely related species. Morphologically, L. olivaceopallidus can be confused with L. uvidus (Fr.) Fr. (GenBank no. KJ742416, KJ742417; Fig. 155), L. violascens (J. Otto) Fr. and L. aspideus (Fr.) Fr. But, L. uvidus (originally described from Europe) differs in having greyish pink to light vinaceous grey pileus, cream to pale pinkish buff lamellae, larger basidiospores 123 Fungal Diversity Fig. 152 Phylogram generated from Bayesian inference analysis of ITS sequence data of species of Phanerochaete sanguinea complex from Floudas and Hibbett (2015) and the new species is marked in grey square. Maximum parsimony and maximum likelihood bootstrap support C 50% (10,000 replicates both), Bayesian posterior probabilities C 0.50 BYPP are shown above the nodes. The tree is rooted with three Phanerochaete species (8.4–11.3 9 6.6–8.5 lm), with shorter ornamentations (up to 0.7 lm) in form of rounded warts and obtuse broad ridges forming an incomplete reticulum. Lactarius violascens (originally reported from Europe) shares similarity in occurrence under deciduous trees but quite different due to greyish buff to brownish violet, azonate or zonate pileus, extracellular pigmentation in pileipellis appearing as dark brown granules and larger basidiospores (7.6 – 11.3 9 6.4–8.5 lm) (Heilmann-Clausen et al. 1998). Like L. olivaceopallidus, a pale basidiome is also present in L. aspideus (originally reported from Europe) which differs from L. olivaceopallidus due to smaller (10–70 mm in diam.) pileus, non-scrobiculate stipe, unchanging latex on isolation from flesh, shorter ornamentations (up to 0.5 lm) in basidiospores, zebroid pattern forming complete to nearly complete reticulum and very thin (40–70 lm) pileipellis (Heilmann-Clausen et al. 1998). Lactarius salicis-reticulatae Kühner (GenBank no. KR090958, KR090959; Fig. 155) is another lilac staining species which is also phylogenetically close (94% similarity for 93–96% query coverage using BLAST) to the present novel species, however, it has subdistant to distant lamellae, mild tasting watery white latex, association with Salix and larger basidiospores (8.5–11.5 9 8–10 lm) (Barge and Cripps 2016). Genetically, Lactarius repraesentaneus Britzelm. (GenBank no. KR090950, KR090954, KR090948, KR090953, JF908312 and KR090952; Fig. 155) is the closest relative (only 95–96% similarity for 93–96% query coverage using BLAST) to L. olivaceopallidus, but morphology of the two species is very different. Lactarius repraesentaneus (originally reported from Europe) has orange-yellow to honey pileus and conspicuously bearded pileus margin (hairs up to 5 mm long). Moreover, L. repraesentaneus is reported growing in ecological 123 Fungal Diversity Fig. 153 Phanerochaete australosanguinea (20102Tell., MA-Fungi 91309, holotype). a Basidiome dry specimen. b Strands, dry specimen. c Substrate stained red. d Basal hyphae thick-walled with clamp. e Probasidia and cystidium. f Basidium stained in congo red. g Cystidium with secondary septa stained in congo red. h Spores.

Scale bars a–d = 10 lm association with Picea, Betula and Salix in temperate to arctic-alpine areas of North America and Europe. Microscopically, it has longer basidiospores (8–10.5 lm) with shorter (B 1 lm high) ridges and ixotrichoderm type of pileipellis. Phylogenetic analyses have suggested 99.4% similarity of L. repraesentaneus with L. dryadophilus Kühner (GenBank no. KR090901), which is very similar to L. repraesentaneus (Barge et al. 2016). Lactarius dryadophilus (originally reported from Europe) is also genetically close to L. olivaceopallidus (95% similarity for 94% query coverage using BLAST) but quite different due to white to pale yellow pileus with bearded margin and larger basidiospores (9.3–11.8 9 7.2–9.2 lm) having very low (B 0.3 lm high) ornamentations (Heilmann-Clausen et al. 1998; Barge et al. 2016). 123 In Asia, Lactarius sect. Uvidi is represented by L. formosus H.T. Le & A.Verbeken and L. pyriodorus K. Das & Verbeken. Lactarius formosus (originally reported from Thailand) is distinct from the present taxon by possessing greyish yellow to yellowish buff, zonate, scaly pileus with bundles of glutinous hairs and cutis to trichoderm type of thick (120–140 lm) pileipellis (Le et al. 2007). Lactarius pyriodorus K. Das & Verbeken (originally reported from Indian Himalaya) cannot be mistaken in the field for L. olivaceopallidus as the former displays brown vinaceous pileus, watery white latex, distinctive pear-like fruity odour and association with Abies. Microscopically, L. pyriodorus has larger basidiospores (8–8.9–10.5 9 6.9–7.5–8.8 lm), with lower (B 1.1 lm high) prominences and thinner (B 320 lm) pileipellis (Das et al. 2015). Fungal Diversity Lactifluus (Pers.) Roussel We follow the latest treatment and updated account of Lactifluus in De Crop et al. (2017) and Hyde et al. (2017). The new species Lactifluus midnapurensis is introduced in Lactifluus subgen. Lactifluus (Burl.) Hesler & A.H. Sm (Fig. 158). Lactifluus midnapurensis S. Paloi & K. Acharya, sp. nov. MycoBank number: MB820587; Facesoffungi number: FoF03248, Figs. 159, 160 Etymology: The specific epithet refers to the type locality, Purba Midnapur (India).

Basidiospores 5.5–6.5–7.1(– 8) 9 (5–)6–6.6–6.9(–7.5) lm, (n = 30) Q = 1.02–1.07– 1.12, globose to subglobose, ornamentation amyloid, composed of short (0.3–0.6 lm) and long warts (1.5–2.0 lm), interconnected by a ridge line, forming a complete reticulum, sometimes connected line are shown wing-like pattern in side view, suprahilar spot amyloid or not. Lamellae edge sterile mainly composed of numerous cheilocystidia. Cheilocystidia 27–48.5 9 4.5–7.5 lm, subclavate to subcylindrical with mostly capitate apex, hyaline, thin-walled, oil droplet present when viewed with KOH. Pleuromacrocystidia 43–61 9 7.5–11 lm, rare toward cap margin but abundant toward cap centre, mostly appendiculate or mucronate, hyaline, thin-walled.

Habit and habitat: Common, solitary or gregarious, growing under Shorea robusta C.F. Gaertn. tree (Dipterocarpaceae). GenBank numbers: ITS = KY785175, LSU = KY785177 (CAL 1516, holotype); ITS = KY785176, LSU = KY785178 (CAL 1523). Notes: The diagnostic features of the newly described species includes small to medium sized (11–48 mm in diam.), convex to infundibuliform or applanate pileus, brownish grey to white that turns reddish orange with guaiacol; distant lamellae, white; slightly excentric stipe; watery latex (transparent); white spore print; mild taste; globose to subglobose basidiospores with a mean size of 7.1 9 6.6 lm, Qm = 1.07, ornamentation composed of warts (up to 2 lm), interconnected with each other forming complete reticulate; pileipellis a palisade type. This combination of characteristics undoubtedly place Lactifluus midnapurensis under subg. Lactifluus sect. Gerardii (Stubbe et al. 2010; De Crop et al. 2017). Lactifluus midnapurensis appears to be related to L. coniculus (Stubbe & Verbeken) Verbeken, described from Sri Lanka growing in association with Shorea sp. However, L. coniculus differs by cigar brown to snuff brown pileus, 123 Fungal Diversity 123 Fungal Diversity b Fig. 155 Phylogeny of Lactarius olivaceopallidus inferred from maximum likelihood analysis of ITS sequence dataset using RAxMLGUI 1.5 (Silvestro and Michalak 2012). Multiple sequence alignment was performed using MAFFT v.7 (Katoh and Standley 2013) with default settings. Alignment was manually edited with Bioedit v 7.2.5 (Hall 1999). To change the multiple alignment format, Alignment Transformation Environment (ALTER) was used (GlezPeña et al. 2010). One-thousand bootstrap replicates were analyzed to obtain nodal support values. TreeGraph2 was used for visualization of the phylogram (Stöver and Müller 2010). The novel species is shown in blue and type strains are in bold. Species of sister genus Lactifluus were selected as the outgroup taxa solid stipe context, comparatively larger basidiospores (7.1–10.2 9 6.4–8.8 lm) with ornamentation like interconnected conical to triangular, round to acute warts and absence of pleuromacrocystidia (Stubbe et al. 2012b). Within the same section, among taxa with similar sized basidiospores, colouration of the latex and growth in association to Dipterocarpus plants, Lactifluus limbatus (Stubbe & Verbeken) Stubbe (described from Malaysia) is a phylogenetically close taxon (Fig. 158). Lactifluus limbatus has a larger pileus (30–60 mm), brownish grey towards centre and grey towards margin, greyish brown lamellar edge, spore ornamentation up to 0.8 lm high and absence of pleuromacrocystidia (Stubbe et al. 2012a, b). Lactarius atrovelutinus J.Z. Ying frequently encountered from China and Malaysia, has a dark black-brown pileus, cream (young) to yellow (mature) lamellae, latex that turns pink or brownish pink on drying, presence of fruity or sweet odour, absence of pleuromacrocystidia and very thick pileipellis (80–100 lm; Ying 1991). Lactarius conchatulus Stubbe & Verbeken, described from northern Thailand (alt. 1300 m), has smaller pileus (2–7 mm diam.) that turns pale yellow on bruising, subdecurrent lamellae, and broadly ellipsoid basidiospores (Q = 1.08–1.35) with up to 0.9 lm long ornamentation (Stubbe et al. 2012a, b). Being a well representative member of the sect. Gerardii; Lactifluus bicolor (Massee) Verbeken, distributed in Malaysia and Singapore, differs from L. midnapurensis in having a larger pileus (20–80 mm diam.), dark brown or fuliginous, longer stipe (10–80 mm), and larger basidiospores (7.5–9.6 9 6.4–8.6 lm) with a ornamentation up to 0.3–0.5 lm high (Massee 1914; Stubbe et al. 2012a, b). A taxon with similar pileus colouration, L. leae Stubbe & Verbeken differs by its very larger pileus (35–120 mm in diam.), somewhat differently sized basidiospores (6.6–12.1 9 5.9–9.1 lm), ornamentation up to 0.5–1 lm high and absence of macrocystidia (Stubbe et al. 2012a, b). Russula Pers. Russula is species-rich and one of the most thoroughly monographed genera of fungi that is mainly ectomycorrhizal with a diverse range of plants in deciduous or evergreen, broadleaf or coniferous woods, scrubland and even meadows from tropical to subalpine areas and has a cosmopolitan distribution (Knudsen and Borgen 1982; Singer 1986; Buyck et al. 1996; Rawla 2001; Das and Sharma 2005; Das et al. 2006a, b, Das et al. 2010, Das et al. 2013, Das et al. 2014, 2017a, b; Miller et al. 2012; Li et al. 2013, 2015; Hyde et al. 2016; Ghosh et al. 2016, 2017; Ghosh and Das 2017). Species within this genus are known by the combination of their conspicuous and fleshy basidiomes, colourful fragile pileus, amyloid warty basidiospores, abundant sphaerocytes in a heteromerous trama that can make these fungi brittle, absence of latex and the hyphae that lack clamp connections (Romagnesi 1967; Singer 1986; Sarnari 1998, 2005). Russula has 10 subgenera namely: R. subg. Compactae, R. subg. Heterophyllidia, R. subg. Ingratula, R. subg. Amoenula, R. subg. Incrustatula and R. subg. Russula, R. subg. Archaea, R. subg. Brevipes, R. subg. Malodora and R. subg. Crassotunicata Buyck & V. Hofstetter (Sarnari 1998; Hongsanan et al. 2015; Das et al. 2017b). Here, two novel species (belonging to subg. Incrustatula and Russula) collected from the northwestern part of Indian Himalaya are described with morphological details and phylogenetic placement (Figs. 161, 162). Russula choptae A. Ghosh & K.

(2017) subcylindrical to cylindrical; in the cap centre, terminal cells subcylindrical to cylindrical, with rounded or obtuse tips, measuring (19–)20–25–29(–35) 9 3–4–4.5(–5) lm; subterminal cells cylindrical. Pileocystidia near the pileus margin aseptate, short to very long, measuring (2.5–)4–5–6(–7) lm broad, subcylindrical to cylindrical, sometimes with lateral projections, obtuse-rounded or sometimes swollen apex, almost completely filled with dense granular content in congo red, distinctly grey-black in sulfovanillin (SV), without incrustations. Pileocystidia near the pileus centre aseptate, short to very long, measuring (3)4–5–6(–8) lm broad, slightly larger, subcylindrical to cylindrical, sometimes with lateral projections, obtuse-rounded or swollen or sometimes forked apex, almost completely filled with dense granular content in congo red, distinctly grey-black in sulfovanillin (SV), without incrustations.

(Fagaceae) in mixed forests dominated by Quercus, Rhododendron (Ericaceae) and Abies (Pinaceae). GenBank numbers: ITS = MG897815 (AG 16–1186); ITS = MG925207 (AG 16–1363). Notes: The combination of macro- and micromorphological features such as, taste being usually acrid or very acrid, epicutis containing well characterized dermatocystidia, yellowish white spore print, often pinkish or lilac stipe, mostly adnate or subdecurrent lamellae and red pilei growing in deciduous forests place Russula choptae under subg. Russula sect. Russula subsect. Sardoninae (Sarnari 1998). In the field Russula choptae is distinct from other species of this group by its brownish red, pale red, pastel red to madder red finely wrinkled pileus with intermixed of pink, orange to yellowish tinge of coral red at the centre, long and slim stipe with yellowish white (1A2) areas or orange white to pale orange (5A2–3) tinge at the base; lamellae with bifurcate, different lengths at the apex of stipe, lamellulae with different lengths (up to 5 series); stipe cuticle and context turns reddish brown and greyish green with guaiacol and KOH, respectively, and micromorphologically it is separated from allied species by different types of cystidial apex (capitate, appendiculate, pointed, mucronate, moniliform or rounded) and basidiospores with warts that are linked as small crests and thick ridges, forming an incomplete network and intermixed with isolated warts. Based on the BLASTn search in NCBIs GenBank nucleotide database, the closest hit using ITS sequences (AG 16-1186 and AG 16-1363) is Russula sp. (voucher HKAS 78400 GenBank no. KF002784) collected from China. Unfortunately, there is no micro- and macromorphological details available for this Chinese collection in published literature. Our phylogeny (Fig. 161) shows R. choptae as sister to this unknown Chinese Russula sp. In subsect. Sardoninae, three species Russula persicina Krombh., R. exalbicans (Pers.) Melzer & Zvára and R. gracillima Jul. Schäff. (also appeared to be close in ITS phylogeny in Fig. 161) resemble R. choptae. However, R. persicina, originally reported from Europe, has larger pileus (40–100 mm), widely spaced rather sinuate lamellae, basidiospores, mostly with isolated warts (0.8 lm) with few crests (Galli 1996; Sarnari 1998; Kränzlin 2005; Knudsen et al. 2012). Russula exalbicans (originally reported from Europe), differs in having larger (50–100 mm diam.), rosered, pink, vinaceous, rapidly becoming paler to almost entirely greenish white pileus usually with a trace of pink at the extreme margin, firm white stipe which soon becomes grey with age or in wet weather, frequent 0–1-septate dermatocystidia, larger basidiospores (7–10 9 5–7 lm) with low (up to 0.75 lm high) ornamentations and ochre spore print (Pearson 1950; Galli 1996; Sarnari 1998; Kränzlin 2005). Russula gracillima (also reported from Europe), differs from R. choptae in possessing moderately spaced lamellae, presence of abundant, broad (5–10 lm) dermatocystidia and basidiospores with isolated blunt warts (Rayner 1985; Galli 1996; Sarnari 1998; Kränzlin 2005; Knudsen et al. 2012; Kibby 2014). Russula renidens Ruots. et al., another taxon in subsect. Sardoninae and originally reported from Europe, has bright crimson red, blood-red to copper red 123 Fungal Diversity Fig. 159 Lactifluus midnapurensis (CAL 1516, holotype). a Fresh basidiomes in the field. b Basidiome showing lamellae side. c SEM microphotograph of basidiospores. d Pleurocystidia. e Pileipellis. Scale bars a, b = 10 mm, c = 5 lm, d = 20 lm, e = 10 lm 123 Fungal Diversity larger pileus (35–80(–100) mm), sulcate margin with age, some intervening lamellae, cylindric to clavate stipe (40–100 9 10–22 mm), basidiospores with low ornamentation (up to 0.5 lm) consisting of small warts with some clusters or ridges, 0–2-septate and slender to clavate dermatocystidia (Galli 1996; Sarnari 1998; Knudsen et al. 2012). Five more taxa of this subsection, Russula sanguinea Fr., R. queletii Fr., R. sardonia Fr., R. torulosa Bres. and R. thindii K. Das & S.L. Mill. also differ from R. choptae. Russula sanguinea, originally reported from Europe, has a coniferous habitat especially under pines and elliptical larger basidiospores (7–9 9 6–7 lm), with ornamentation consisting mostly of solitary warts which are somewhat elongated (only a few with connections) (Rayner 1985; Sarnari 1998; Kränzlin 2005; Knudsen et al. 2012). Russula queletii (originally reported from Europe) can be distinguished by presence of a combination of characteristics i.e. vinaceous red to violet pileus and stipe, strong fruity odour and changing of pilear context to light vinaceous red with FeSO4 (Rayner 1985; Saini and Atri 1989; Sarnari 1998; Kränzlin 2005; Knudsen et al. 2012). Similarly, R. sardonia, originally reported from Europe, differs in having dark violaceous purple, reddish purple or livid vinaceous pileus, sometimes with greyish olivaceous or with yellowish patches; solid and firm stipe; slightly larger basidiospores (7–9 9 6–7 lm) and is mycorrhizal with Pinus on acid soil (Sarnari 1998; Knudsen et al. 2012). Russula torulosa (originally reported from Europe) possess purple-violet, purple-red, violet-red or dark red pileus sometimes with lighter ochraceous or olivaceous spots, often blackish at centre; solid and firm stipe; larger basidiospores (7.2–9.5 9 5.6–7.3 lm) with low ornamentations (0.4–0.6 lm) and is found mostly under Pinus sp. (Sarnari 1998; Knudsen et al. 2012). Russula thindii (originally reported from India) is distinct by its larger pileus (38–77 mm diam.), pale yellow spore print and larger basidiospores (7.5–9–10 9 6–7–8 lm), with ornamentation composed mostly of isolated conical to spinoid warts being occasionally connected by fine connectors (Das et al. 2014). In Eastern Asia, Russula choptae might be confused with R. chiui G.J. Li & H.A.Wen, R. zhejiangensis G.J. Li & H.A. Wen and R. minutula var. minor Bi (originally described from China). However, R. chiui differs in having brightly red tinged pileus, white stipe, septate pileocystidia, densely reticulate larger basidiospores [(8–)8.5–10(– 10.5) 9 7–8(–8.5) lm] and sterile lamellar edge (Li et al. 2015). Russula zhejiangensis has a purely white stipe, isolated conical to obtuse warts in basidiospores, shorter pleurocystidia (35–74 9 6–11 lm) with mostly rounded or mucronate apex, sterile lamellar edge and 0–3-septate pileocystidia (Li et al. 2011). Russula minutula var. minor, described in Guangdong Province of South China, differs by its white to yellowish gills, white stipe, isolated spinoid basidiospores and shorter pleurocystidia (Bi and Li 1986; Li et al. 2011). Russula uttarakhandia A. Ghosh & K. Das, sp. nov.

Primordial hyphae comparatively longer than the other extremities and often protruding or repent on the cap surface, occurring mostly singly, composed of 5–7–9(–10) lm broad, cylindrical cells, obtuse apex, thick-walled (up to 1 lm thick); incrustations present. Clamp connections and laticiferous hyphae absent from all tissues. Material examined: INDIA, Uttarakhand, Rudraprayag District, Baniyakund, alt 2634 m, N30°28.9140 0 E79°10.854 , 17 July 2015, A. Ghosh, AG 15-670 (CAL 1537, holotype); ibid., alt 2560 m, N30°292070 E79°10.2580 , 24 July 2016, A. Ghosh, (AG 16-1190 paratype). Habitat and distribution: Under Quercus sp. in mixed forests dominated by Quercus, Rhododendron and Abies. GenBank numbers: ITS = KY873997 (CAL 1537); ITS = MF684758 (AG 16-1190). Notes: The combination of macro- and micromorphological features such as: epicutis with primordial hyphae, absence of dermatocystidia, mild taste, yellow to ochre spore print, nonpruinose cap and epicutis with clavate hyphal ends undoubtedly place Russula uttarakhandia under subg. Incrustatula, sect. Amethystinae subsect. Chamaeleontinae (Sarnari 1998). In the field R. uttarakhandia is distinct from other known species of this group by its pinkish white or reddish white to venetian pink and centrally olive yellow to greyish yellow gelatinous, glossy pileus; stipe that turns pink or red rose after sometime with application of guaiacol, pale yellowish cream spore print. Micromorphologically, it is separated from allied species by the combination of various shapes of cystidial apex (distinctively appendiculate cystidia with long appendages up to 23 lm long). Based on the BLASTn search in NCBIs GenBank nucleotide database, the closest hit using ITS sequences of Russula uttarakhandia (collection numbers AG 15-670 and AG 16-1190) is Russula sp. (voucher HMAS 277786 collected from China, GenBank no. LT602960), showing 96% similarity with 98% query coverage. Unfortunately, there is no morphological details available for this Chinese collection in any published literature. Our phylogeny (Fig. 162) clearly shows that R. uttarakhandia is genetically closer and sister to unknown Chinese Russula sp. (LT602960). In subsection Chamaeleontinae, Russula postiana Romell and R. risigallina (Batsch) Sacc. also appeared to be close in ITS phylogeny with R. uttarakhandia (Fig. 162). But, R. postiana (originally reported from Europe), differs from R. uttarakhandia by its herbage green to yellowish green, smooth, shining pileus; bright ochre yellow lamellae, heavily encrusted primordial hyphae, slightly larger basidiospores (8–10.2 9 7–8 lm) and its occurrence under coniferous trees (Galli 1996; Kibby 2014). Russula risigallina (also originally reported from Europe), differs from R. uttarakhandia by its red or orange pileus often with paler yellow centre (sometimes entirely yellowish opaque), strongly intervened egg yellow to almost orange lamellae and deep yellow spore print (Galli 1996; Sarnari 2005; Kibby 2014). Another taxon of this subsect., R. lutea (Huds.) Gray (also appeared in the BLASTn search), originally reported from Europe, separated from R. uttarakhandia by its entirely yellow, apricot or coral pileus, deep ochre gills and deep ochraceous spore print (Rayner 1985; Kibby and Fatto 1990). Considering the cap colouration, R. uttarakhandia may also be confused in the field with R. gracillima Jul. Schäff., R. cremeirubra Murrill, R. robertii J. Blum, R. nitida (Pers.) Fr. and R. decipiens (Singer) Svrcek. However, R. gracillima (originally described from Europe) possess moderately spaced lamellae, a little acrid taste, presence of abundant broad dermatocystidia (5–10 lm) and basidiospores with isolated blunt warts (Rayner 1985; Galli 1996; Sarnari 1998; Chou and Wang 2005; Kibby 2014). Russula cremeirubra (originally reported from Florida) has rather distant straw coloured lamellae, basidiospores with amyloid warts connected by fine lines or connectors which combine to form few meshes and broken reticulum, pilear hyphae (2–6 lm broad) with acute to rounded apex (Murrill 1945; Hesler 1960; Kibby and Fatto 1990; Fatto 1998). Russula robertii (originally described from Europe) has 1–2-septate, slender dermatacystidia (3–5 lm broad) and spores with many crests and connectives forming partial to complete reticulum (Sarnari 2005; Kibby 2014). Russula nitida (originally reported from Europe) has pale straw-yellow gills, sometimes with reddish edge near the cap margin, larger basidiospores (8–10.5(–12) 9 6.5–8(–9) lm) with rather sharp spines (up to 1.2 lm high), isolated or variously connected, and abundant dermatocystidia with 1–3 septation (Rayner 1985; Galli 1996; Sarnari 2005). 123 Fungal Diversity 123 Fungal Diversity b Fig. 161 The ITS sequence of the newly generated Russula species (Russula choptae) plus those acquired from GenBank, UNITE database and relevant literature, were aligned with the help of AliView (Larsson 2014) using default settings. Sequences of ITS were phylogenetically analyzed using Bayesian inference analysis (BI). Bayesian inference was computed independently twice in MrBayes v.3.2.2 (Ronquist et al. 2012). The best-fit substitution model of nucleotide evolution (TIMef) was carried out in MrModeltest 3.7 (Posada and Crandall 1998). Posterior probabilities (PP) were calculated in two simultaneous runs with Markov chain Monte Carlo (MCMC) algorithm (Larget and Simon 1999). Markov chains were run for 1000000 generations, saving a tree every 100th generation. Default settings in MrBayes were used for the incremental heating scheme for the chains (3 heated and 1 cold chain), unconstrained branch length [unconstrained: exponential (10.0)] and uninformative topology (uniform) priors. The analysis was terminated when the average standard deviation of split frequencies fell below 0.01. The first 25% of trees were discarded as burn-in (Hall 2004). The convergence of runs was visually assessed using Trace function in Tracer version 1.6 (Rambaut et al. 2013). The novel species having GenBank no. MG897815 and MG925207 (ITS) are shown in blue and bold on the tree and ex-type strains are in bold. Russula pseudoamoenicolor and R. violeipes are considered as the outgroup taxa Russula decipiens (belonging to subg. Russula), originally reported from Europe has slightly infundibuliform pileus, yellowish white stipe that slightly becomes grey on bruising, acrid taste and presence of aseptate, subclavate to clavate dermatocystidia (Rayner 1985; Sarnari 1998). In field, Russula uttarakhandia may be confused with R. rajendrae A. Ghosh & K. Das (originally described from India and also collected from Uttarakhand, Rudraprayag District, Baniyakund), but the latter possess an acrid taste, numerous pileocystidia in cuticle and belongs to subg. Russula (Ghosh and Das 2017). Considering the acystidiate aspect of pileipellis and mild taste (key characters of subg. Incrustatula), Russula uttarakhandia is also similar to other taxa of subg. Incrustatula reported from India viz. R. sharmae K. Das et al., R. dafianus K. Das & J.R. Sharma, R. dhakuriana K. Das et al., R. hookeri S. Paloi et al. and R. kewzingensis K. Das et al. However, R. sharmae (reported for the first time from West District of Sikkim) possess red to scarlet with yellow blotched larger pileus (70–140 mm), absence of lamellulae, smaller basidiospores (6.8–7.3–7.9 9 6–6.6–7 lm) and palisade to trichopalisade type of pileipellis (Das et al. 2013). Russula dafianus (reported from Dafia Dhura, Uttarakhand) has smaller basidiomes (35–45 mm), yellowish white to pale yellow lamellae and encrusted pilear hyphae (Das and Sharma 2005). Russula dhakuriana (reported from Dhakuri, Uttarakhand) has more robust basidiomes (pileus 80–120 mm diam., stipe 50–125 9 20–28 mm), longer basidiospores (6.5–10.2 9 6–7.7 lm) and pleurocystidia (60–115 9 7–12 lm) and cellular nature to the subpellis (Das et al. 2006a). Russula hookeri (reported from Darjeeling Hill, Eastern Himalaya) has small to medium basidiomes (20–35 mm), greyish red to greyish rose pileus with brownish red centre, concolorous stipe; smaller basidiospores (5.4–7.2 9 4.5–6.4 lm) and white spore print (Paloi et al. 2015). Russula kewzingensis (reported from Kewzing, Sikkim Himalaya) has deep and intense red pileus, red-flushed stipe and pseudoparenchymatous nature of subpellis (Das et al. 2017b). Stereaceae Pilát The family Stereaceae was proposed by Pilát (1930) with Stereum Hill ex Pers. as generic type. This family is one of the most widespread and diverse in the Russulales, together with Russulaceae. It includes species with basidiome appressed, effuse-reflexed or discoid, rarely stalked; pileus often zoned; monomitic or dimitic hyphal system; hymenophore smooth to tuberculate; basidia and spores hyaline, smooth, amyloid or non-amyloid. The family comprises species that grow in exposed positions, such as dead branches still attached to hardwood or conifer trees, causing white rot (Miller et al. 2006; Larsson 2007). Aleurodiscus Rabenh. ex J. Schröt. Aleurodiscus is one of the largest genera in Stereaceae. It was proposed by Rabenhorst (1874) without diagnosis, and validated by Schröter in (1888), with Peziza amorpha Pers. (: Aleurodiscus amorphus (Pers.) J. Schröt.) as type species. Pilát (1926) included Aleurodiscus corticioid fungi with large basidia and large spores, as well as variable sterile elements and this concept was largely accepted (Bourdot and Galzin 1912, 1928; Burt 1918). Lemke (1964a, b) considered the genus to be artificial and proposed to exclude species with inamyloid spores, and described the following new genera: Aleurocystidiellum Lemke, Aleurocorticium Lemke and Licrostroma Lemke. On the basis of morphological and molecular data, Wu et al. (2000) described Acanthofungus Sheng H. Wu et al. with Acanthofungus rimosus Sheng H. Wu et al. as type species, and Neoaleurodiscus Sheng H. Wu with Neoaleurodiscus fujii Sheng H. Wu as type species. From a phylogenetic perspective, Wu et al. (2001) analyzed the limits of Aleurodiscus sensu lato and the monophyly of previously segregated genera, concluding that Aleurocystidiellum and Acanthobasidium are monophyletic. However, subsequent studies (Larsson and Larsson 2003; Miller et al. 2006; Larsson 2007) have shown that Aleurocystidiellum does not belong to Stereaceae. Wu et al. (2001) set the boundaries of Aleurodiscus sensu stricto and confirmed that Aleurodiscus sensu lato is paraphyletic. According to Wu et al. (2001), Aleurodiscus sensu lato includes species with highly variable characteristics; these are not congruent and usually overlap, so the species in Aleurodiscus sensu lato show all possible combinations of spore surface from smooth or ornamented, presence or absence of acanthophyses, and hyphae with clamps or 123 Fungal Diversity Fig. 162 The ITS sequence of the newly generated Russula uttarakhandia plus those acquired from GenBank, UNITE database and relevant literature, were aligned with the help of AliView (Larsson 2014) using default settings.

Notes: Phylogenetic analysis based on a combined ITS and LSU sequence dataset (Fig. 169) shows that Aleurodiscus patagonicus clusters within Stereaceae, far away from the Aleurodiscus sensu stricto clade, which includes only A. amorphous (Pers.) J. Schröt. (type species) and A. grantii Lloyd (Wu et al. 2001). Aleurodiscus sensu lato is paraphyletic; sequencing shows species of apparently unrelated genera intermingled with the species of Aleurodiscus sensu lato (Wu et al. 2001, 2010b; Larsson and Larsson 2003; Binder et al. 2005; Miller et al. 2006). In the phylogeny (Fig. 169), A. patagonicus groups in a highly supported clade (99% ML, 99% MP and 1.00 PP), which is sister to the A. limonisporus D.A. Reid clade and this relationship is also highly support (92% ML, 90% MP and 1.00 BYPP). Aleurodiscus patagonicus is similar to A. limonisporus. Both species have a monomitic hyphal system, cylindrical paraphysoid hyphae, and characteristic citriform smooth spores. However, A. patagonicus differs in the following characteristics: clamps present in paraphysoid hyphae, longer and wider basidia, with basal clamp, and, spores with higher length/width ratio, as well as, in the geographical distribution (Table 3). Aleurodiscus patagonicus is reported from Chilean Northern Patagonia, while A. limonisporus occurs in Australia (Reid 1955) and New Zealand (McKenzie et al. 2000). Trechisporales K.H. Larsson Hydnodontaceae Jülich Hydnodontaceae was described by Jülich (1981) with Hydnodon Banker as generic type, and includes Brevicellicium K.H. Larss. & Hjortstam, Cristelloporia I. Johans. & Ryvarden and Trechispora P. Karst. Hydnodon is now considered as a synonym of Trechispora (Ryvarden 2002). This family was characterized by the resupinate, effusedreflexed or pileate basidiome, hymenophore smooth to hydnoid or poroid, as well as by the ampulate septa, short cylindrical basidia and ornamented spores. The family concept was revised by Larsson (2007), on the basis of morphological and molecular data, and Brevicellicium, Fibriciellum J. Erikss. & Ryvarden, Fibrodontia Parmasto, Luellia K.H. Larss. & Hjortstam, Porpomyces Jülich, Subulicystidium Parmasto, Trechispora and Tubulicium Oberw. were included. Trechispora P. Karst. Trechispora was erected by Karsten (1890) to include only one species, Trechispora onusta P. Karst. (= Trechispora hymenocystis). This genus was characterized by its adnate basidiomes, poroid hymenophore, with hyaline and ornamented spores. Trechispora was treated by Bondartsev and Singer (1941), and Rogers (1944, 1951), and the initial description was amended by Liberta (1966) to include species with clamped hyphae, ampulate septa and smooth spores. Liberta (1973), in his monograph, introduced new morphological criteria for species delimitation, such as shape and size of spores, as well as the spore surface (smooth or ornamented), hyphal system (monomitic or dimitic), and hymenophore configuration (smooth, poroid or hydnoid), and this species concept was followed in all subsequent treatments. Larsson (1994, 1995a, b, 1996) gave detailed micromorphological studies, described new taxa, proposed new combinations and recognized the morphology of crystal deposits on subicular hyphae as a reliable character for species delimitation. Most species of Trechispora have been described from boreal and temperate zones, growing on deeply decayed wood and other debris on the ground, although Matssura and Yashiro (2010) reported an insect-fungus association between a termite species (Reticulotermes termites) and an undescribed trechisporoid fungus (Trechispora sp.) from Japan. Trechispora contains 82 legitimate names (Index Fungorum 2019). According to Hjortstam and Ryvarden (2007), 27 species have been reported from tropical and subtropical areas. Trechispora echinospora sp. nov. is introduced from Equatorial Guinea. Trechispora echinospora Telleria, M. Dueñas, I. Melo & M.P. Martı́n, sp. nov.

Line drawings were made with a Leyca DM2500 microscope with aid of a drawing tube by M. Dueñas. Scale bars = 10 lm Trechispora obtained by our team were deposited in GenBank under Trechispora sp. because many specimens were collected in tropical areas, and require a thorough study of their morphology to clearly identify them to the species level. In this paper, ITS sequences from 13858Tell. and 13861Tell. collected during our study of the corticoid fungi from Equatorial Guinea (Centro Sur Province), growing on Oxythenantera abyssinica (A.Rich.) Munro, were compared with sequences available in the EMBL/GenBank/ DDBJ (Cochrane et al. 2011) and UNITE (Abarenkov et al. 2011; Kõljalg et al. 2013) databases, mainly from Larsson et al. (2004), Lutzoni et al. (2004), Krause et al. (2011), Brazee et al. (2012, 2014), Sjökvist et al. (2012), Telleria 123 Fungal Diversity et al. (2013), and Ordynets et al. (2015). The sequences were analyzed under maximum parsimony (MP), maximum likelihood (ML) and Bayesian inference (BI). The BI tree is shown in Fig. 170, including the MP and ML bootstrap values, as well as the posterior probabilities. The five sequences from these collections, group together in a highly supported clade (85% MP, 99% ML and 1.00 BYPP), sister group of the clade formed by Trechispora araneosa (Höhn. & Litsch.) K.H. Larss., T. farinacea (Pers.) Liberta, T. hymenocystis (Berk. & Broome) K.H. Larss. and T. mollusca (Pers.) Liberta, although this relationship is not well-supported. These collections from Equatorial Guinea show unique morphological characteristics, such as the spores being globose and echinulate with straight prickles, striking under SEM (Fig. 171). The morphological characteristics and molecular phylogenetic results, its habitat on dead stem of bamboo, and its geographical distribution led us to propose the new species, T. echinospora. Subclass Auriculariomycetidae Jülich Auriculariales J. Schröt. Auriculariaceae Fr. Ex Lindau Auriculariaceae, typified by Auricularia mesenterica (Dicks.) Pers. (= Helvella mesenterica Dicks.), belongs to Auriculariales and comprises nine genera and 155 species (Kirk 2017). The family includes species with resupinate, effused-reflexed, hydnoid, cerebriform and pileate basidiomes; thin or thick-walled probasidia and metabasidia, both varying from globose to cylindrical and thin-walled basidiospores that germinate by tubes or producing conidia (Lowy 1971; Martin 1952). The most common genera of Auriculariaceae are Auricularia Bull., Heterochaete Pat., Exidia Fr., Eichleriella Bres., Exidiopsis (Bref.) A. Møller and Hirneolina (Pat.) Bres. Tremellochaete Raitv. Tremellochaete was described by Raitviı́r (1964) with T. japonica (Lloyd) Raitv. (= Exidia japonica Lloyd) as the type species and comprises two legitimate species (Kirk 2017). The genus is characterized by tough-gelatinous basidiomes, often becoming softer with age, varying from tuberculate-erumpent and effused-tuberculate; papillate hymenium, papillae heavily encrusted with irregular, hyaline crystals; metabasidia with 2- or 4-celled; and allantoidsuballantoid, hyaline, aseptate basidiospores. Tremellochaete is similar to Exidia, which has fewer papillae (Raitviı́r 1964), and has been considered a synonym of the latter. However, Tremellochaete was reinstated after morphological and phylogenetic analyses (Malysheva and Spirin 2017). We follow the treatments and updated accounts in Malysheva and Spirin (2017). The new species, T. atlantica is introduced based on phylogenetic analysis of 123 a combined ITS and LSU sequence dataset coupled with morphological characteristics (Fig. 172). Tremellochaete atlantica Alvarenga, sp. nov. MycoBank number: MB823716; Facesoffungi number: FoF05728, Fig. 173 Etymology: The name refers to the phytophysiognomy where it was collected. Holotype: URM 90199 Colour codes follow: Methuen Handbook of Colour (Kornerup and Wanscher 1978). Basidiomes yellowish to greyish or brown (1B, 2A, 5E, 4D) when fresh, greyish brown to yellowish brown (3F, 8E) when dry, foliose, 2.5–3 9 3.5 cm, gelatinous, densely papillate, papillae 50–107.5 9 40 lm, encrusted with irregular, hyaline crystals not dissolving in KOH, margin detaching from the substrate, marginal hairs present in tufts, 50–212 lm or absent, subhymenial hyphae with ochraceus, granular content. Basidia with complete septum, 2- or 4-celled, hyaline, ovoid, 9–12(–13) 9 6–9(–10) lm, clamped at the base. Basidiospores allantoid to reniform, 7.8–10(–12) 9 2–5 lm, thin-walled, IKI-. Hyphal system monomitic, hyphae clamped, thin-walled, hyaline, 1–2 lm in diam. Cystidia absent. Material examined: BRAZIL, Pernambuco: Igarassu, Refúgio Ecológico Charles Darwin, May 2017, R.L.M. Alvarenga, RLMA 491 (URM 90198); ibid., Pernambuco: Recife, Centro de Biociências, near the Departamento de Zoologia, Universidade Federal de Pernambuco, June 2017, R.L.M. Alvarenga, RLMA 477 (URM 90199 holotype; isotype in O). GenBank numbers: ITS = MG594382, LSU = MG594384 (URM 90198); ITS = MG594381, LSU = MG594383 (URM 90199). Notes: Tremellochaete atlantica is recognized by the marginal hairs ranging from 50–212 lm and the heavily encrusted papillae with hyaline, irregular crystals. It is similar to T. japonica and T. nigerima (Viégas) Spirin & V. Malysheva. Tremellochaete japonica (type locality Japan) differs by the darker basidiomes, fewer dark hyphae, smaller papillae (60–75 lm), absence of marginal hairs and slightly smaller basidiospores (9.5–12 9 4–4.5 lm) (Roberts 2006), while T. nigerima (type locality Brazil) has larger metabasidia and basidiospores (20–25 9 10–15 lm and 17–20 9 7–8 lm, respectively) (Viégas 1945). Tremellochaete hispidula (Lowy) Raitv. (= Exidia hispidula Lowy, from USA) also has marginal hairs (up to 125 lm), but lacks clamps, has larger metabasidia [(7–)8– 10 9 (10–)12–16] and ovoid to allantoid basidiospores [(9–13(–14.5) 9 5–7)] (Lowy 1957). This species, however, is illegitimate, because Exidia hispidula Berk. has priority over E. hispidula Lowy.

(2016) and Shirouzu et al. (2017). Dacrymycetales Henn. Dacrymycetaceae J. Schröt. Dacrymycetaceae was introduced by Schröter (1889), with the genera Calocera (Fr.) Fr., Dacrymyces Nees, Dacryomitra Tul. & C. Tul. and Guepinia Fr. Nowadays, according to Oberwinkler (2014) this family contains ten genera: Arrhytidia Berk. & M.A. Curtis, Calocera, Dacrymyces, Dacryomitra, Dacryonaema Nannf., Dacryopinax G.W. Martin, Ditiola Fr. (= Guepinia), Femsjonia Fr., Guepiniopsis Pat. and Heterotextus Lloyd. The species included in this family are characterized by the form of basidiome: pustulate, cupulate, clavate, or sometimes branched; gelatinous when fresh and usually yellow or orange. The hyphal system is monomitic, the basidia bifurcate, with two well-developed sterigmata and the spores are usually septate germinating by conidia or germ tubes. All species are wood-decaying and cause brown rot (Oberwinkler 1993). The genera in this family have been delimited according to morphological criteria such as the shape of basidiome, the position of the hymenium, and presence or absence of a specialized cortex (Kobayasi 1939; McNabb 1973; Reid 1974). Phylogenetic studies (Weiß and Oberwinkler 2001; Shirouzu et al. 2007, 2009, 2013, 2017) showed that Calocera, Cerinomyces, Dacrymyces, and Dacryopinax are polyphyletic, suggesting that the traditional taxonomy should be revised. We follow the treatment and updated accounts in Shirouzu et al. (2017) as well as following Reid (1974) for taking into account Dacrymyces sensu lato. The species of this genus are characterized by the basidiomes being gelatinous when fresh, at first pustular, becoming pulvinate, discoid or turbinate, sometimes stipitate; hymenium amphigenous, or restricted to the upper surface; hyphal system monomitic; hyphidia simple, or somewhat branched, with or without clamp connections; basidia clavate becoming bifurcate; spores cylindrical, ellipsoid, allantoid, ovate or subglobose, becoming variously septate at maturity and germinating by conidia or germ-tubes. The novel species, Dacrymyces invisibilis is introduced based on morphological characteristics coupled with ITS phylogenetic analyses (Fig. 174). Dacrymyces invisibilis M. Dueñas, Telleria & M.P. Martı́n, sp. nov. MycoBank number: MB825361; Facesoffungi number: FoF05729, Figs. 175, 176 Etymology: From Latin ‘‘invisibilis’’ not visible, refers to dry basidiome difficult to see. 123 Holotype: 14597MD, MA-Fungi 91306. Basidiomes pustulate at first, pulvinate to discoid, confluent, 0.5–3 mm diam., gelatinous, white, becoming varnish-layered when dry; hymenophore amphigenous, smooth; margin determinate. Hyphal system monomitic. Hyphae thin- to thick-walled, smooth, or incrusted, loosely interwoven, sparsely ramified, 2–4 lm wide, without clamps.

Dueñas, M.P. Martı́n & M.T. Telleria, 14617MD (MA-Fungi 91307). Habitat and distribution: Known from the Valdivian temperate rainforest in the Chilean Northern Patagonian region, growing on unidentified wood. GenBank numbers: ITS = MH230100 (14597MD, MAFungi 91306); ITS = MH230101 (14617MD, MA-Fungi 91307). Notes: Previous ITS/LSU analyses (data not shown) of Dacrymyces invisibilis, and 119 homologous sequences from Shirouzu et al. (2017), included this taxon with D. subantarcticensis Burds. & Laursen described from New Zealand (Burdsall and Laursen 2004). However, morphological and molecular features clearly separate the two taxa. In this paper, a shorter and more accurate alignment is reported, including the species closest to D. subantarcticensis in Shirouzu et al. (2017): D. aureosporus Shirouzu & Tokum., D. chrysospermus Berk. & M.A. Curtis, D. dictyosporus G.W. Martin, D. minor Peck, D. subalpinus Kobayasi, D. stillatus Nees and Guepiniopsis buccina (Pers.) L.L. Kenn. In the UPGMA tree (Fig. 174) based on Kimura-2-parameters, the genetic distances proposed in Schoch et al. (2012) as barcode analyses, are shown, including the parsimony bootstrap and maximum likelihood support values, as well as the Bayesian posterior probabilities. The two collections from Chile form a wellsupported group (81% MP, 78% ML and 1.00 BYPP) indicating that D. invisibilis is distinct from D. subantarcticensis. In addition, in this figure a small part of the alignment (around positions 189 and 246) is included to show some of the variable positions between these two Fungal Diversity Fig. 170 Phylogram generated from Bayesian inference analysis of ITS sequence dataset of Trechispora sequences. Maximum parsimony and maximum likelihood bootstrap support values C 50% (10,000 replicates both), and Bayesian posterior probabilities C 80% are shown above the nodes. The tree is rooted with Brevicellicium exile and B. olivascens. Newly generated sequences are marked in blue and ex-type strains are in bold species. Dacrymyces invisibilis and D. subantarcticensis have basidiomes nearly invisible when dry, and thin-walled spores, with three septa, but they differ in the size of basidia and spores, smaller in D. subantarcticensis (20–30 9 5 lm and 10–13 9 4.5–6 lm, respectively). Dacrymyces subalpinus, D. aureosporus, D. chrysospermus and D. dictyosporus form a subclade close to D. subantarcticensis and D. invisibilis; all of them have spores with more than three septa at maturity. Dacrymyces subalpinus and D. aureosporus are known only from Japan (Kobayasi 1939; Shirouzu and Hosoya 2017). Dacrymyces chrysospermus has been widely reported and D. dityosporus is known from Honduras, and Mexico (Lowy 1971).

The phylogenetic tree was generated by partial concatenated analyses of the ITS and LSU sequence dataset. Only species with at least the LSU sequences were considered for the phylogeny. The sequences obtained in this study were aligned with other from GenBank in MEGA6 (Tamura et al. 2013) and edited using the Staden Package 2.0 software (Staden et al. 1998). Sistotrema brinkmannii (Bres.) J. Erikss. was used as outgroup taxa. Prior to phylogenetic analyses, the model of nucleotide substitution was estimated using Topali 2.5 (Milne et al. 2004). Bayesian inference analyses [two runs over 2 9 106 generations with a burn in value of 25% and maximum likelihood (1000 bootstrap)] were performed, respectively, in MrBayes 3.1.2 (Ronquist et al. 2012) and PhyML (Guindon and Gascuel 2003) launched from Topali 2.5, using the GTR ? G model. Sequences obtained in this study are in blue. Support values are maximum likelihood (BSML) and Bayesian posterior probability (BYPP). Only support values of at least 50% are shown Mucoraceae Dumort. We follow the latest treatment and updated accounts of Mucoraceae in Spatafora et al. (2016), Tibpromma et al.

(2018) based on an evolutionary ecological analysis. collected from the gardens of Chonnam National University, Gwangju, Korea, a new species of Mucor was isolated and is described here. Recently, only three new Mucor species have been reported in Korea: M. koreanus Hyang B. Lee et al. from tangerine fruit (Li et al. 2016); M. stercorarius Hyang B. Lee et al. from rat faeces (Tibpromma et al. 2017); and M. fluvii Hyang B. Lee et al. from freshwater (Wanasinghe et al. 2018) (Fig. 177). Mucor Fresen. The genus Mucor was described by Fresenius (1850), and comprises the largest number of species within the Mucorales (Benny et al. 2014). They are readily isolated from soil, fruits, vegetables, stored grains, insects or dung (Benny 2008). Several species are of great interest to the biotechnology industry because of their ability to produce proteolytic enzymes (de Souza et al. 2015), while some species are considered as the causal agents of cutaneous zygomycosis in humans (Ribes et al. 2000).

Optimal growth was observed around 25–30 °C, slow growth was observed below 10 °C, and no growth at 40 °C. Material examined: REPUBLIC OF KOREA, Jeonnam Province, garden of Chonnam National University located in Gwangju (35° 090 16.9900 N, 126° 540 56.0200 E), from fecal sample of praying mantis, October 2017 (CNUFC- Fungal Diversity Fig. 177 Phylogenetic tree of Mucor orantomantidis (CNUFC-MID1-1 and CNUFCMID1-2), and related species based on a maximum likelihood analysis of a combined ITS and LSU sequence dataset. The sequence of Backusella oblongispora was used as outgroup taxon. Numbers at the nodes indicate the bootstrap values ([ 50%) from 1000 replications. The bar indicates the number of substitutions per position. New taxa are shown in blue and ex-type strains in bold MID1-1, holotype); isotype in Korean Agricultural Culture Collection (KACC, Wanju, Korea); ex-type living culture, JMRC:SF:013605 (deposited at Jena Microbial Resource Collection, University of Jena and Leibniz Institute for Natural Product Research and Infection Biology, Jena, Germany and preserved as glycerol stock at -80 °C in the CNUFC). GenBank number: ITS = MH594737, LSU = MH591457 (CNUFC-MID1-1); ITS = MH594738, LSU = MH591458 (CNUFC-MID1-2). Notes: The phylogenetic analyses of a combined ITS and LSU sequence dataset (Fig. 177) show that Mucor orantomantidis belongs to M. amphibiorum group as defined by Walther et al. (2013). Mucor orantomantidis is closely related to Mucor sp. ‘hiemalis’. However, M. orantomantidis differs from Mucor sp. ‘hiemalis’ by producing zygospores with equal or unequal suspensors, and by having larger sporangiospores. M. orantomantidis grows and sporulates at 35 °C, whereas, the maximum temperature for Mucor sp. ‘hiemalis’ is around 30 °C. In addition, the strain forms a separate branch from other species of the genus, showing it represents a new species in the phylogenetic tree (Fig. 177). 123 Fungal Diversity Fig. 178 Mucor orantomantidis (CNUFC-MID1-1, holotype). a A praying mantis. b Colony in potato dextrose agar. c Colony in synthetic mucor agar. d Colony in malt extract agar. e, f Sporangiophores and sporangia. g, h Columellae with collarette. i Sporangiospores. j–m Zygospores.
