Abstract

This is a continuity of a series of taxonomic and phylogenetic papers on the fungi where materials were collected from many countries, examined and described. In addition to extensive morphological descriptions and appropriate asexual and sexual connections, DNA sequence data are also analysed from concatenated datasets to infer phylogenetic relationships and substantiate systematic positions of taxa within appropriate ranks. Wherever new species or combinations are proposed, we apply an integrative approach using morphological and molecular data as well as ecological features wherever applicable. Notes on 112 fungal taxa are compiled in this paper including Biatriosporaceae and Roussoellaceae, Didysimulans gen. nov., 81 new species, 18 new host records and new country records, five reference specimens, two new combinations, and three sexual and asexual morph reports. The new species are Amanita cornelii, A. emodotrygon, Angustimassarina alni, A. arezzoensis, A. italica, A. lonicerae, A. premilcurensis, Ascochyta italica, A. rosae, Austroboletus appendiculatus, Barriopsis thailandica, Berkleasmium ariense, Calophoma petasitis, Camarosporium laburnicola, C. moricola, C. grisea, C. ossea, C. paraincrustata, Colletotrichum sambucicola, Coprinopsis cerkezii, Cytospora gelida, Dacrymyces chiangraiensis, Didysimulans italica, D. mezzanensis, Entodesmium italica, Entoloma magnum, Evlachovaea indica, Exophiala italica, Favolus gracilisporus, Femsjonia monospora, Fomitopsis flabellata, F. roseoalba, Gongronella brasiliensis, Helvella crispoides, Hermatomyces chiangmaiensis, H. chromolaenae, Hysterium centramurum, Inflatispora caryotae, Inocybe brunneosquamulosa, I. luteobrunnea, I. rubrobrunnea, Keissleriella cirsii, Lepiota cylindrocystidia, L. flavocarpa, L. maerimensis, Lophiotrema guttulata, Marasmius luculentus, Morenoina calamicola, Moelleriella thanathonensis, Mucor stercorarius, Myrmecridium fluviae, Myrothecium septentrionale, Neosetophoma garethjonesii, Nigrograna cangshanensis, Nodulosphaeria guttulatum, N. multiseptata, N. sambuci, Panus subfasciatus, Paraleptosphaeria padi, Paraphaeosphaeria viciae, Parathyridaria robiniae, Penicillium punicae, Phaeosphaeria calamicola, Phaeosphaeriopsis yuccae, Pleurophoma italica, Polyporus brevibasidiosus, P. koreanus, P. orientivarius, P. parvovarius, P. subdictyopus, P. ulleungus, Pseudoasteromassaria spadicea, Rosellinia mearnsii, Rubroboletus demonensis, Russula yanheensis, Sigarispora muriformis, Sillia italica, Stagonosporopsis ailanthicola, Strobilomyces longistipitatus, Subplenodomus galicola and Wolfiporia pseudococos. The new combinations are Melanomma populina and Rubroboletus eastwoodiae. The reference specimens are Cookeina tricholoma, Gnomoniopsis sanguisorbae, Helvella costifera, Polythrincium trifolii and Russula virescens. The new host records and country records are Ascochyta medicaginicola, Boletellus emodensis, Cyptotrama asprata, Cytospora ceratosperma, Favolaschia auriscalpium, F. manipularis, Hysterobrevium mori, Lentinus sajor-caju, L. squarrosulus, L. velutinus, Leucocoprinus cretaceus, Lophiotrema vagabundum, Nothophoma quercina, Platystomum rosae, Pseudodidymosphaeria phlei, Tremella fuciformis, Truncatella spartii and Vaginatispora appendiculata and three sexual and asexual morphs are Aposphaeria corallinolutea, Dothiora buxi and Hypocrella calendulina.

Materials and methods

Sampling, isolation and identification

Specimens in this study were collected from Brazil, China, Croatia, Germany, India, Italy, Korea, Russia, Sri Lanka, Thailand and the UK. Soil samples to isolate Gongronella brasiliensis were collected from Taquaritinga do Norte, state of Pernambuco, Brazil, following methods outlined in Benny (2008). Gongronella brasiliensis was cultured in triplicate, in MEA and PDA, and incubated at 10, 15, 20, 25 and 30 °C, over 7 days. Colony characteristics were recorded, while alternative morphs were induced in culture using sterilized pieces of plant material (Phookamsak et al. 2015). Plant material was examined with a Carl Zeiss GmbH (AxioCam ERC 5 S) stereo microscope. Fruiting bodies of ascomycetes were rehydrated in water, lactic acid or 5% KOH. Cut sections were observed with a compound microscope; micro-morphological characteristics (e.g. ascomata sections, peridium structures, asci and ascospores in ascomycetes and basidia, cystidia, basidiospores in basidiomycetes) were examined, described and photographed. Measurements (e.g. from basidiospores and ascospores) were taken from at least 20 representatives and the mean and the standard deviation for length and width, together with the range of spore quotient (Q, the length/width ratio) and its mean value (Qm) are given. Herbarium specimens and ex-type living cultures were deposited in various collections and are listed under each taxon description. Facesoffungi numbers (FoF) and Index Fungorum (IF) numbers were obtained as explained in Jayasiri et al. (2015) and Index Fungorum (2017). New species were established as per recommendations outlined by Jeewon and Hyde (2016).

DNA extraction, PCR amplification and sequencing

For most ascomycetous fungal samples, total genomic DNA was extracted from fresh fungal mycelium grown on appropriate media at 16 °C or room temperature (as outlined by Jeewon et al. 2002), while for basidiomycetes, dry fruiting bodies were used. DNA was extracted following the instructions of the Biospin Fungus Genomic DNA Extraction Kit (BioFlux^®, Hangzhou, P.R. China) or other fungal DNA extraction kits according to the manufacturer’s instructions. When fungi failed to grow in culture, DNA was extracted directly from ascomycete fruiting bodies using aseptic techniques. For Gongronella brasiliensis, fungal biomass was obtained in MEA cultures in test tubes kept at 28 °C for up to six days and genomic DNA extraction of G. brasiliensis was carried out with previously macerated material according to Góes-Neto et al. (2005).

DNA amplification for all samples was performed by Polymerase Chain Reaction (PCR) using universally standard primers. The primers used and PCR conditions are shown in the Table 1. For Gongronella brasiliensis specimens, thermal profiling and amplification reactions of ITS regions were conducted as described by Oliveira et al. (2014) and the final amplicons were purified with the PureLink PCR Purification Kit (Invitrogen), sequenced directly or cloned with a Clone JETTM PCR Cloning Kit (Fermentas; Carlsbad, USA), following the manufacturer’s instructions. The quality of the PCR products was checked by electrophoresis on 1% agarose gels. Purification and sequencing of PCR products (with same primers used in PCR) was done by commercial sequencing providers depending on the regions where the studies were carried out.

Sequence alignment and phylogenetic analyses

A careful verification of sequence data generated in this study was carried out with appropriate reference sequences following BLAST searches in the nucleotide database of GenBank (http://blast.ncbi.nlm.nih.gov/). It was ensured that no erroneous sequences were used in the further analyses and then data were submitted to GenBank. Following sequence verification and Blast search, DNA sequences from appropriate taxonomic ranks were downloaded based on recent publications to construct datasets for phylogenetic analyses. BioEdit sequence alignment editor (Hall 1999), CLUSTALX (Larkin et al. 2007), Mega 6.0.5 (Tamura et al. 2013) and MAFFT: multiple sequence alignment software version 7.215 (Katoh et al. 2002) were used for sequence alignment. Under most circumstances, concatenated DNA datasets were analyzed to generate phylogenetic trees, but in cases of limited availability of DNA sequences from respective gene regions, phylogenies were inferred from single or a combination of two gene datasets and either a consensus of these gene phylogenies or one of the most parsimonious phylogenies was used to infer phylogenetic relationships across taxa sampled. Selection of outgroup(s) for rooting purposes was based on knowledge of potential common ancestors to the in-group as well as taxon sampling from previously published studies. Phylogenetic analyses were performed by neighbor joining (NJ), maximum parsimony (MP), maximum likelihood (RAxML) and Bayesian inference (BI) analyses. The maximum parsimony analyses were performed using PAUP v. 4.0b10 (Swofford 2003), bootstrap analysis with 1000 replicates. All multiple, equally parsimonious trees were saved and descriptive tree statistics for parsimony consistency index (CI), retention index (RI), rescaled consistency index (RC) and homoplasy index (HI) were calculated. Other details are as described by Jeewon et al. (2003b, 2004, 2013), Hu et al. (2007) and Promputtha et al. (2007). The robustness of the best parsimonious tree was estimated by a bootstrap (BT) value with 1000 replicates, each with 100 replicates of random stepwise addition of taxa (Liu et al. 2011, 2012). Maximum likelihood (ML) analysis was performed using RAxMLGUI v. 1.3 (Silvestro and Michalak 2010) with 1000 rapid bootstrap replicates. The substitution model comprised a generalized time reversible (GTR) for nucleotides with a discrete gamma distribution (Silvestro and Michalak 2012). Bayesian analyses were performed by MrBayes v. 3.0b4 (Ronquist and Huelsenbeck 2003) with the best-fit model of sequence evolution estimated with MrModeltest 2.2 as described in Nylander et al. (2008). Markov Chain Monte Carlo sampling (BMCMC) was used to determine the posterior probabilities (PP) (Rannala and Yang 1996; Zhaxybayeva and Gogarten 2002) in MrBayes v. 3.0b4 (Ronquist and Huelsenbeck 2003). Six simultaneous Markov chains were run at least 1000,000 generations or depending on individal settings for the fungal group and trees were sampled every 100th/1,000th generation (Cai et al. 2006). Tracer v. 1.6 (Rambaut and Drummond 2003) was used to check the effective sampling sizes (ESS) and burn-in value. The run was stopped automatically as soon as the average standard deviation of split frequencies fell below 0.01 (Maharachchikumbura et al. 2015). Phylograms were visualized in Treeview (Page 2001) or FigTree 1.4.2 (Rambaut 2014) with bootstrap values above or below the nodes and reorganized in Adobe Illustrator CS v. 6., Microsoft Powerpoint (v.2007), portable document format (PDF) and Adobe Photoshop version CS3 (Adobe Systems, USA). All the sequences generated in this study were deposited in GenBank and accession numbers have been provided where appropriate.

Dothideomycetes

Dothideomycetes is the largest class of Ascomycota. In this study, we follow the classifications in the recent studies of Hyde et al. (2013) and Wijayawardene et al. (2014a).

Asterinales M.E. Barr ex D. Hawksw. & O.E. Erikss.

Hyde et al. (2013) accepted Asterinaceae, Aulographaceae, and Parmulariaceae in Asterinales and a revision of genera in Asterinales was provided by Hongsanan et al. (2014). In recent publications members of Asterinales clustered in two clades (Ertz et al. 2016; Hyde et al. 2016). Hyde et al. (2016) treated the Asterinales clade (not clade containing Parmulariaceae) as Asterinales sensu stricto, because most of the Asterinales strains, from both Asterina and Lembosia clustered in this clade and also because the large clade that contains Asterinales as circumscribed by Ertz et al. (2016) does not have any phylogenetic support. Hyde et al. (2016) also synonymized the younger Asterotexiales under Asterinales. In this paper, we provide an updated tree for Asterinales (Fig. 1).

Asterinaceae Hansf.

The family Asterinaceae has characteristic superficial, web-like, black colonies on the upper and lower surfaces of leaves (Hyde et al. 2013). Hofmann et al. (2010) placed Asterinaceae in Dothideomycetes based on multi-gene sequences, and this was substantiated by Hongsanan et al. (2014).

Morenoina Theiss

= Aulographella Höhn.

Morenoina was introduced by Theissen (1913) with Morenoina antarctica (Speg.) Theiss. as the type species. Morenoina resembles Aulographum, differing only in the morphology of the scutellum, which comprises inordinately arranged cells and a hypostroma of subcuticular hyphae beneath the thyriothecium (Ellis 1980).

Morenoina calamicola Konta & K. D. Hyde, sp. nov.

Index Fungorum number: IF552661; Facesoffungi number: FoF02757, Fig. 2

Holotype: MFLU 15-0013

Saprobic on Calamus sp. Sexual morph Thyriothecia 100–325 μm, occurring on host surface, solitary, aggregated, or gregarious, easily removed from the host surface, superficial, ellipsoid, oblong, curved, flat, with longitudinal, slit-like opening, linear fissure, which are branched at the margin, from the center to the outer rim, lacking free hyphae and appressoria at the margin, in transverse Sect. 24–33 µm high × 86–121 µm diam. (\( \bar{x} \) = 27 × 103 μm, n = 5). Upper wall comprising linear cells, with irregular, filiform hyphae, radiating from the center to the outer rim. Asci 13–20 × 10–17 μm (\( \bar{x} \) = 17 × 14 μm, n = 10), 8-spored, bitunicate, globose to subglobose or clavate, or saccate to globose, apedicellate, with a distinct, thickened apical region. Ascospores 9–11 × 3–4 μm (\( \bar{x} \) = 10 × 3.9 μm, n = 10), irregularly arranged, oblong or fusiform, wider at apex, with slightly acute ends, 1–septate, with two large guttules in each cell, hyaline, smooth-walled. Asexual morph Undetermined.

Culture characteristics: Ascospores germinating on MEA within 24 h and germ tube produced from each cell. Colonies on MEA reaching 3–4 cm diam., after 5 days, grey to olivaceous, dense, with fairly fluffy surface, hyphae, septate, branched and smooth-walled.

Material examined: THAILAND, Chiang Mai Province, on dead stem of Calamus sp. (Arecaceae), 11 August 2014, Sirinapa Konta, P04a (MFLU 15-0013, holotype; ex-type living culture, MFLUCC 14-1162).

GenBank Numbers LSU: KY511424; ITS: KY511430; SSU: KY511427.

Notes: Hongsanan et al. (2014) transferred Morenoina to Aulographaceae based on morphology and phylogeny. In the current phylogenetic analyses, Morenoina calamicola clustered with Melaspilea lekae (Melaspileaceae) (94% in ML, 1.00 in BYPP). The morphology of Morenoina calamicola is distinct and Melaspilea lekae is lichenicolous (Kalb et al. 2012). Morenoina calamicola is similar to Aulographaceae (Asterinales) in lacking appressoria and flattened, elongate thyriothecia, opening by a slit. In the phylogenetic analyses (Fig. 1) Morenoina calamicola is well-separated from Aulographaceae.

Morenoina calamicola is most similar to M. palmicola J. Fröhl., K.D. Hyde & Joanne E. Taylor in characteristics of asci, ascospores and host genus (Calamus australis), but differs in the size and shape of ascospores.

Botryosphaeriales C.L. Schoch et al.

Botryosphaeriales is a diverse order with a worldwide distribution, comprising species that vary from endophytes to pathogens (Slippers and Wingfield 2007; Phillips et al. 2013; Chethana et al. 2016; Daranagama et al. 2016; Dissanayake et al. 2016; Giambra et al. 2016; Konta et al. 2016a, b; Linaldeddu et al. 2016a, b, c; Manawasinghe et al. 2016; Tennakoon et al. 2016; Zhang et al. 2017). Since it was introduced by Schoch et al. (2006) this order has undergone significant taxonomic changes with the addition of several new families. Currently, nine families are recognized, namely, Aplosporellaceae, Botryosphaeriaceae, Endomelanconiopsisaceae, Melanopsaceae, Phyllostictaceae, Planistromellaceae, Pseudofusicoccumaceae, Saccharataceae and Septorioideaceae (Schoch et al. 2006; Minnis et al. 2012; Wikee et al. 2013; Slippers et al. 2013; Wyka and Broders 2016; Dissanayake et al. 2016; Yang et al. 2017), although several authors considered this to be too many (Chethana et al. 2016; Daranagama et al. 2016; Dissanayake et al. 2016; Giambra et al. 2016; Konta et al. 2016a, b; Linaldeddu et al. 2016a, b, c; Manawasinghe et al. 2016; Tennakoon et al. 2016; Liu et al. 2016; Zhang et al. 2017).

Botryosphaeriaceae Theiss. & Syd.

The family Botryosphaeriaceae was described in the 1820s, originally for species of Sphaeria (Fr.) (Crous et al. 2006; Schoch et al. 2006). von Arx and Müller (1954). Barr (1987) included only nine genera, which are mostly different from those of von Arx and Müller (1954). Hawksworth et al. (1995) listed five genera. Lumbsch and Huhndorf (2010) included eleven genera, while Hyde et al. (2011) and Wijayawardene et al. (2012) listed 16 genera. Liu et al. (2012) included 17 genera in the family based on molecular data and examination of generic types. Phillips et al. (2013) provided comprehensive descriptions, notes and phylogenies for the 17 genera and 110 species known from cultures. Twenty-three genera and 187 species of Botryosphaeriaceae were listed by Dissanayake et al. (2016).

Barriopsis A.J.L. Phillips, A. Alves & Crous

Barriopsis was introduced when Phillips et al. (2008) transferred Physalospora fusca to Barriopsis fusca. Stevens (1926) originally placed this species in Physalospora, but was obviously hesitant to do so on account of its brown ascospores. Petrak and Deighton (1952) then transferred it to Phaeobotryosphaeria as P. fusca. Although von Arx and Müller (1954) considered Phaeobotryosphaeria a synonym of Botryosphaeria, Phillips et al. (2008) showed that it is morphologically and phylogenetically distinct from other genera in Botryosphaeriaceae. However, the fungus considered by Stevens (1926) and Petrak and Deighton (1952) does not have apiculi on its ascospores, and thus does not fall within the concept of Phaeobotryosphaeria, which has small, hyaline apiculi on the ascospores. For this reason Phillips et al. (2008) introduced the genus Barriopsis. Dissanayake et al. (2016) list four species.

Barriopsis thailandica Dissanayake, Senan. & K.D. Hyde, sp. nov.

Index Fungorum number: IF551363; Facesoffungi number: 00913, Figs. 4, 5

Etymology: Name refers to the country Thailand, where the fungus was collected. Holotype: MFLU 15-1414

Saprobic on decaying bark of Tectona grandis L.f. Sexual morph Ascostromata 170–220 μm high × 150–170 μm diam. (\( \bar{x} \) = 194 × 160 μm, n = 10), scattered, initially immersed, becoming erumpent through bark when mature, solitary or gregarious, uniloculate, globose to subglobose, or flask-shaped when cut horizontally, coriaceous, ostiolate, papillate. Papilla 70–80 × 60–65 μm (\( \bar{x} \) = 77 × 64 μm, n = 10), short, periphysate. Periphyses 15–20 μm (\( \bar{x} \) = 20 μm, n = 10), brown, curved towards the outside, long, flat, leaf-like. Peridium 20–45 μm wide (\( \bar{x} \) = 30 μm, n = 10) comprising outer, 5–10 layers of brown, thick-walled, large cells of textura angularis to textura globulosa and inner, 4–7 layers of hyaline, thin-walled, small cells of textura angularis to textura globulosa. Hamathecium comprising 2–4 μm wide (\( \bar{x} \) = 3.5 μm, n = 10), hypha-like, numerous, septate, pseudoparaphyses, slightly constricted at septa.

Ascospores 15–20 × 9–11 μm (\( \bar{x} \) = 18 × 10 μm, n = 30), mostly biseriate, rarely overlapping uniseriate, ellipsoidal or rhomboidal, inequilateral, wider in the center, initially hyaline, becoming yellow, pale brown to reddish-brown when mature, aseptate, ends blunt when mature, thick-walled, smooth-walled or verruculose. Asexual morph Conidiomata stromatic, uniloculate, dark brown to black. Hamathecium 20–35 μm long (\( \bar{x} \) = 28 μm, n = 20), hyaline, cylindrical, mostly aseptate, sometimes branched, ends slightly swollen and rounded, arising amongst the conidiogenous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 4–7 × 4–6 μm (\( \bar{x} \) = 6.5 × 5 μm, n = 20), hyaline, smooth, cylindrical, slightly swollen at the base, enteroblastic, proliferating percurrently to form one or two closely spaced annellations. Conidia 15–19 × 7.5–8.5 μm (\( \bar{x} \) = 17 × 7.8 μm, n = 20), ellipsoidal at apex, rounded at base, widest at the center, thick-walled, initially hyaline, aseptate, becoming 1-septate, dark brown, striated after released from the conidiomata.

Material examined: THAILAND, Uttaradit Province, on decaying bark of Tectona grandis (Lamiaceae), 12 October 2014, I.C. Senanayake (MFLU 15-1414, holotype), ex-type living culture MFLUCC 14-1190, KUMCC 16-0185.

GenBank Numbers ITS:KY115675; TEF1:KY115676.

Notes: Barriopsis is one of the less well-known genera in the family Botryosphaeriaceae. To date only four species; Barriopsis archontophoenicis, B. fusca, B. iraniana and B. tectonae have been reported for this genus (Phillips et al. 2008; Abdollahzadeh et al. 2009; Doilom et al. 2014, Konta et al. 2016a, b). Barriopsis tectonae has both sexual and asexual morphs (Doilom et al. 2014; Konta et al. 2016a, b). We describe both a sexual and asexual morph for Barriopsis thailandica (Figs. 4, 5). The asexual morph formed in culture grown on MEA (Fig. 5). In the phylogenetic analysis of combined ITS and TEF1 sequence data, this new taxon is related to B. iraniana (Fig. 3), but phylogenetically distinct with very good support (100% maximum parsimony and 1.0 in Bayesian analysis) to justify its establishment as a new species. The small conidial dimensions of B. thailandica (17 × 8 μm, L/W ratio = 2.1) clearly distinguish it from B. iraniana (27 × 16 μm, L/W ratio = 1.6). The asexual morph has not been reported for B. iraniana, whereas that of B. thailandica is reported herein.

Capnodiales Woron.

The order Capnodiales introduced by Woronichin (1925) was accepted in Dothideomycetes based on phylogenetic studies (Schoch et al. 2006, 2009; Crous et al. 2009; Chomnunti et al. 2014). The Capnodiales are mainly defined by their shared ecological niches (Hughes 1976; Crous et al. 2009; Chomnunti et al. 2011; Hyde et al. 2013).

Mycosphaerellaceae Lindau

Mycosphaerellaceae is a large family in the order Capnodiales (class Dothideomycetes). Species in Mycosphaerellaceae have cosmopolitan distributions, occurring on various hosts worldwide (Crous et al. 2009, 2013a, b; Schoch et al. 2009; Farr and Rossman 2012; Hyde et al. 2013; Quaedvlieg et al. 2013). Some genera of Mycosphaerellaceae e.g. Cercospora, Pallidocercospora, Pseudocercospora and Septoria contain important and well known pathogens, causing serious diseases of economic crops (Crous et al. 2007, 2009, 2013a, b; Cheewangkoon et al. 2008; Schoch et al. 2009; Hyde et al. 2013; Quaedvlieg et al. 2013). Several sexual genera in Mycosphaerellaceae are morphologically similar, but can be distinguished by their asexual morphs (Crous et al. 2007, 2009, 2013a, b). Many phylogenetic studies of the asexual genera in Mycosphaerellaceae have been carried out (Crous and Braun 2003; Crous et al. 2007, 2009, 2013a, b; Quaedvlieg et al. 2013). However, phylogenetic affinities of sexual genera such as Achorodothis, Polythrincium (=Cymadothea), Euryachora, Gillotia, Melanodothis, Polyascosporella and Wernerella are largely unresolved partially due to limited availability of collections and DNA sequence data (Hyde et al. 2013). The phylogeny of Polythrincium trifolii is shown in Fig. 6.

Polythrincium Kunze

Polythrincium was introduced in Kunze and Schmidt (1817) and is typified by P. trifolii Kunze. Polythrincium trifolii is an obligate pathogen causing sooty blotch of clover in temperate regions (Simon et al. 2005a, b, 2009; Rossman et al. 2015). The sexual morph of Polythrincium has been reported as Cymadothea trifolii (Wolf 1935) and it is characterized by small, black, pustulate ascostromata on the lower surface of clover leaflets, bitunicate, clavate asci, lack of pseudoparaphyses and hyaline to subhyaline, oblong to clavate and 1-septate ascospores (Wolf 1935; Simon et al. 2009).

Polythrincium is relatively poorly studied with only seven epithets in Index Fungorum (2017), but rDNA based phylogenies indicate that P. trifolii belongs to the family Mycosphaerellaceae (Simon et al. 2009).

Mycelium immersed, brown to dark brown, smooth-walled. Sexual morph reported as Cymadothea trifolii (Wolf 1935). Asexual morph hyphomycetous forming on lower surface of leaves. Sporodochia 40–120 µm high, 35–80 µm diam., with cushion-like pseudoparenchymatous cells at the base, composed of compact, fasciculate, foot-like cells at the base, with tightly aggregated, parallel, cylindrical to subcylindrical conidiophores. Conidiophores (25–)30–60(–62) × (4.5–)5–7 µm (\( \bar{x} \) = 45.1 × 6.2 µm, n = 50), macronematous, mononematous, caespitose, erect to flexuous, unbranched, aseptate, torsive, brown to dark brown, smooth-walled, largely ampulliform at the base, undulated at the upper part. Conidiogenous cells polyblastic, sympodial, integrated, terminal, cylindrical, undulate, with large, cicatrized scars.

Notes: Polythrincium trifolii differs from P. shiraianum Henn. and P. trifolii var. platense Speg. in having larger conidia (P. shiraianum = 15–30 × 7–8 µm and P. trifolii var. platense = 16–18 × 12–14 µm) (Hennings 1905; Spegazzini 1910). Polythrincium lathyrinum Syd. has conidia of a similar size (P. trifolii: (21–)24–27(–29) × (13–)15–17(–19) µm; P. lathyrinum: 22–32 × 15–18 µm), but occurs on Lathyrus maritimus Willd. (Farr and Rossman 2012) (Sydow 1928). while P. trifolii has been reported from Trifolium, Astragalus sinicus L. (from China) and Stemphylium sarcinaeforme (Cavara) Wiltshire. Phylogenetic analyses based on combined LSU and ITS sequence data show that P. trifolii belongs to Mycosphaerellaceae and concurs with Simon et al. (2009). This is the first report on T. repens from China.

Dothideales Lindau

Thambugala et al. (2014b) revised the order Dothideales and synonymized Dothioraceae under Dothideaceae, and accepted only two families in the order.

Dothioraceae Theiss. & Syd.

Dothideaceae was established by Chevallier (1826) as “Dothideae”, and later Fuckel (1870) introduced Dothidea as the type genus and D. gibberulosa (Fr.) Fr. as the type species. The characteristic features of Dothideaceae are immersed to erumpent or superficial, 1 or multi-loculate ascostromata; 8-or polysporous, bitunicate asci and hyaline or brown, transversely septate, sometimes muriform (Dothiora Fr.) ascospores (Thambugala et al. 2014b). Dothideaceae was revised by Thambugala et al. (2014b) who included ten sexual genera and five asexual genera. The phylogeny of Dothiora buxi along with other members of the Dothideaceae is shown in Fig. 8.

Dothiora Fr.

Dothiora was introduced by Fries (1849) with D. pyrenophora (Fr.) Fr. as the type species. Thambugala et al. (2014b) based a study of Dothiora on both morphology and phylogeny.

Dothiora buxi Jayasiri, Camporesi & K.D. Hyde, in Fungal Diversity 81: 30 (2016)

Facesoffungi number: FoF00078, Fig. 9

Saprobic and/or parasitic on dying leaves and twigs (hemibiotrophic) of Buxus sempervirens L. Sexual morph in Hyde et al. 2016. Asexual morph Conidiomata 182–263 µm high × 383–447 µm diam. (\( \bar{x} \) = 232 × 422 μm, n = 5), pycnidial, globose to subglobose, scattered, solitary, visible as brown to black, pustulate on the lower leaf surface, semi-immersed to erumpent, exposed by breaking leaf epidermis. Peridium 21–43 μm wide, comprising 1–3 layers of thickened, pale brown, cells arranged in textura prismatica. Conidiogenous cells 11–17 × 6–11 µm diam. (\( \bar{x} \) = 14 × 9 μm, n = 10), phialidic, subglobose, hyaline. Conidia 10–16 × 6–19 µm diam. (\( \bar{x} \) = 13 × 7 μm, n = 10), ellipsoid to obovoid, rounded at top, narrow at base, guttulate, smooth, 1-celled, hyaline.

Culture characteristics: Colonies on MEA, reaching 2–2.5 cm diam. after 10 days at 16 °C, flat, margin with entire edge, white, producing conidiomata and numerous conidia.

Material examined: RUSSIA, Rostov Region, Shakhty City, 20th anniversary of Red Army microdistrict, street plantation, street shrubs, dying leaves and twigs (hemibiotrophic) of Buxus sempervirens, 1 May 2015, T. Bulgakov, T421 (MFLU 15-2356, asexual morph); living culture MFLUCC 15-0823.

GenBank Numbers LSU:KY511425; SSU:KY511428 (Fig. 10).

Notes: Fries (1849) introduced the genus Dothiora, with D. pyrenophora (Fr.) Fr. as the type species. In the current study, the phylogenetic analyses indicate that our strain is closely related to Dothiora buxi Jayasiri, Camporesi & K.D. Hyde (MLFU 15-3404) with 92% bootstrap support. The morphology could not be compared as the latter was reported in its sexual morph with no information on its asexual morph (Hyde et al. 2016). However, we found the asexual morph on the same host, Buxus sempervirens. In culture, conidiomata were produced from germinated ascospores after one week’s incubation. Conidiomata, conidiogenous cells, and conidia found in culture are similar to those of D. buxi found on the host. Thus, we introduce the new record of asexual morph of D. buxi based on the morphological and phylogenetic evidence.

Hysteriales Lindau

The order Hysteriales, consisting of a single family, was introduced by Lindau (1896). DNA sequence data showed that Hysteriales should be accommodated in Dothideomycetes (Boehm et al. 2009a, b; Shearer et al. 2009; Suetrong et al. 2009). This order is characterized by carbonaceous navicular ascoma with a longitudinal dehiscent slit and ascospores that are typically dark and vary in septation (Boehm et al. 2009a).

Hysteriaceae Chevall.

Chevallier (1826) introduced the family Hysteriaceae as ‘Hysterineae’. This family has been treated with different genera by authors (Zogg 1962; von Arx and Muller 1975; Kirk et al. 2001; Lumbsch and Huhndorf 2010). Recent multi-gene phylogenetic studies placed Hysteriaceae in Hysteriales, Pleosporomycetidae (Boehm et al. 2009a, b; Hyde et al. 2013; Wijayawardene et al. 2014a; Thambugala et al. 2016).

Hysterium Tode

Hysterium was introduced by Persoon (1797) with H. pulicare Pers. as type species. The genus is characterized by pigmented, versicolorous or concolorous, asymmetric phragmoascospores, three- or more transversely-septate, borne in hysterothecia (Boehm et al. 2009a).

Hysterium centramurum Senan. sp. nov.

Index Fungorum number: IF552708; Facesoffungi number: FoF00164, Figs. 11, 12

Etymology: The species epithet from the combination of two Latin words “centrum” and “murum”, meaning centre and septum or wall, in reference to the ascospore having a median septum.

Holotype: MFLU 14-0096

Saprobic on decaying wood. Sexual morph Ascomata 0.9–1.8 mm long, 400–450 µm wide, 370–380 µm high (\( \bar{x} \) = 1250 × 400 × 375 µm, n = 20), a hysterothecium, scattered, superficial, base immersed in substrate, elongate and depressed conchate, globose, surface black, shiny, longitudinally striate, apex compressed, opening by longitudinal slit. Periphyses aseptate, hyaline with swollen ends. Peridium 30–45 µm wide (\( \bar{x} \) = 34 µm, n = 10), carbonaceous, brittle, of heavily pigmented, small, prosenchymatous cells. Hamathecium comprising 0.75–0.85 µm wide (\( \bar{x} \) = 0.8 µm), aseptate, branched, trabeculate pseudoparaphyses, borne in a gel matrix which is pinkish and granular above the asci. Asci 170–195 × 30–55 µm (\( \bar{x} \) = 179 × 36 µm, n = 20), 8-spored, bitunicate, oblong to clavate, with a short pedicel, apically thickened, with a distinct ocular chamber. Ascospores 110–130 × 20–25 µm (\( \bar{x} \) = 125 × 23 µm, n = 20), crowded to biseriate, fusiform when young, oblong at maturity, with a single median septum, hyaline to light yellow, wall greatly thickened towards the apex, cytoplasm clearly subdivided into numerous compartments in Melzer’s and Cotton blue reagent, muriform when mature, endoplasts appearing cup-shaped when young, smooth-walled. Sheath present, but not very obvious. Asexual morph coelomycetous. Conidiomata 100–110 µm (\( \bar{x} \) = 107 µm), superficial, solitary or aggregated, black to brown, appearing as a mycelium mass, prosenchymatous, without a prominent wall. Conidiophores 8–10 µm long × 1–2 µm wide (\( \bar{x} \) = 9 × 1 µm), cylindrical, attached to the mycelium, hyaline. Conidiogenous cells 2–2.5 × 1–1.5 µm (\( \bar{x} \) = 2.4 × 1.2 µm), holoblastic, terminal or intercalary on conidiophores, cylindrical, short, smooth, hyaline. Conidia 2–2.5 µm diam. (\( \bar{x} \) = 2.3 µm, n = 20) oval to globose, hyaline, brown when mature.

Culture characteristics: Colonies on MEA, greenish-white, circular, with smooth margin, slow growing, attaining 2 cm diam. within 60 days at 20 °C, tightly arranged, short, aerial mycelium. Orange-brownish exudates released into the media. The mycelial mats produce erumpent, globose, light brownish, viscous droplets when incubated at 20 °C for 3 weeks and later becoming lighter in colour.

Material examined: THAILAND, Chiang Mai Province, Doi Suthep-Pui, Sangasabhasri Lane to Huai Kok Ma Village (N1848.62′, E9854.60′, elev. 1145 m), on decaying wood, 17 December 2012, I.C. Senanayake CHUNI 70 (MFLU 14-0096, holotype, HKAS 82633, isotype), ex-type living culture MFLUCC 12-0808.

GenBank Numbers ITS:KM272258; LSU:KM272256; SSU:KM272257; TEF1:KM277819.

Notes: Hysterium centramurum is morphologically similar to Ostreichnion curtisii (Duby) M.E. Barr and O. thailandicum Tennakoon, Phookamsak & KD Hyde. However, phylogenetically, our strain is not closely related to the type species of Ostreichnion, O. sassafras. Combined gene sequences analysis of LSU, SSU and TEF1 (Fig. 10) places H. centramurum in the genus Hysterium. Morphologically H. centramurum differs from other Hysterium species in having hyaline to light yellow ascospores, surrounded by a sheath, with a median septum. Additionally, the coelomycetous asexual morph for this species was obtained in culture. The major secondary metabolic exudate produced in cultures of H. centramurum was identified by mass spectroscopy and 1D and 2D NMR spectroscopy data analysis as physcion (1,8-dihydroxy-6-methoxy-3-methyl-9,10-dioxoanthracene-2-carboxylic acid), which is useful in the textile industry as a dye and in the pharmaceutical industry as an antibiotic and anti-cancer agent (Velmurugan et al. 2010).

Hysterobrevium mori (Schwein.) E.W.A. Boehm & C.L. Schoch, Stud. Mycol 64: 62 (2009)

Facesoffungi number: FoF 2766, Fig. 13

Saprobic dead branch of Cornus sanguinea L. Sexual morph Ascomata 200–220 µm high × 240–290 µm diam. (\( \bar{x} \) = 209 × 262 μm, n = 5), superficial on wood, elongate, narrowly elliptical to fusiform, straight or irregularly curved, solitary or scattered on the host surface, dull black, carbonaceous, with a conspicuous longitudinal cleft and often with inconspicuous parallel striations, the cleft gradually widening to expose the hymenium, not easier to remove. Peridium 45–65 μm wide, thick, composed of very dark, near opaque, thick-walled brown to black cells, basal region similar, with a layer of hyaline thin-walled cells forming the cavity floor, dull cells arranged in a textura angularis to textura globulosa. Hamathecium of 1.2–2.2 µm wide, long cylindrical, hyaline, smooth, septate, branched, cellular, pseudoparaphyses. Asci 50–70 × 10–20 μm (\( \bar{x} \) = 61 × 16 μm, n = 15), 8-spored, bitunicate, cylindrical to clavate, with short pedicel, tapering to a rounded or irregular base, thick-walled. Ascospores 15–21 × 5–10 μm (\( \bar{x} \) = 19 × 7 μm, n = 20), mostly ellipsoidal, muriform, usually with 3–4 transverse septa and 1–2 longitudinal septa, with slightly paler ends, conical and narrowly rounded at the ends, hyaline, with mucilaginous sheath. Asexual morph Undetermined.

Culture characteristics: Colonies on MEA at 16 °C reaching 4 cm in two weeks, circular with undulate, yellow-grey mycelium, velvety and flat on the media.

Material examined: ITALY, Forlì-Cesena Province, Castrocaro Terme, dead branch of Cornus sanguinea (Cornaceae), 6 January 2012, Erio Camporesi, IT86 (MFLU 15-1476, HKAS 94526, new host record); living culture, MFLUCC 14-0520).

GenBank Numbers LSU:KY496718; ITS:KY496739; SSU:KY501109; RPB2:KY514403.

Notes: Phylogenetically this species resides in a distinct subclade in Hysterobrevium and is H. mori (Fig. 10). Our new isolate from Italy matches H. mori in having ellipsoidal, hyaline, muriform ascospores, with 3–4 transverse septa and 1–2 longitudinal septa that pass through one to two cells, with a mucilaginous sheath. Thus, we confirm (based on both morphological characteristics and phylogenetic data) that our taxon belongs to H. mori even though it was found on a different host (Cornus sanguinea). Previously, H. mori has been reported from many hosts, such as Acer, Amelanchier, Aspidosperma, Castanea, Cercocarpus, Cotinus, Crataegus, Fraxinus, Gleditsia, Juniperus, Melia, Morus, Olea, Ostrya, Pinus, Pistacia, Prunus, Pyrus, Quercus, Rhus, Rubus, Salix, Ulmus, various Fabaceae, Vitis and Ziziphus (Zogg 1962).

For an account of Pleosporales Luttr. ex M.E. Barr see Zhang et al. (2012b) and Hyde et al. (2013).

Amorosiaceae Thambugala & K.D. Hyde

Amorosia was introduced by Mantle et al. (2006) with A. littoralis Mantle & D. Hawksw. Previous studies, based on phylogenetic analysis, have referred it to the Sporormiaceae (Mantle et al. 2006), but Thambugala et al. (2015a) introduced Amorosiaceae as a new family for this species and described three new species of Angustimassarina in this family. We introduce six new species of Angustimassarina based on morphology and phylogeny (Fig. 14).

Angustimassarina Thambug., Kaz. Tanaka & K.D. Hyde

Thambugala et al. (2015a) introduced Angustimassarina to accommodate three new ascomycetous species placed in the family Amorosiaceae. The members of the genus are considered as fungicolous or they may be parasitic on other fungi and appear to grow within other ascomata or on other ascomycetes. A synopsis of Angustimassarina species is provided (Table 2).

Angustimassarina alni Jayasiri & K.D. Hyde, sp. nov.

Index Fungorum number: IF552551; Facesoffungi number: FoF 2689, Fig. 15

Etymology: The specific epithet alni is based on the host genus.

Holotype: MFLU 16-2981

Saprobic on Alnus glutinosa (L.) Gaertn. Sexual morph Ascomata 160–250 µm high × 130–200 µm diam. (\( \bar{x} \) = 208 × 188 μm, n = 5), scattered to gregarious, immersed to semi-immersed, carbonaceous, dark brown to black, globose to subglobose. Ostiolar canal inner layer lined with black to dark brown cells, outer layer with dark brown to black pseudoparenchymatous cells, with a pore like opening or opening through cracks in the host surface. Peridium 28–44 µm wide, equally thick, comprising dark brown to black cells of textura angularis. Hamathecium comprising 1–1.5 µm septate, unbranched, cellular pseudoparaphyses, embedded in gelatinous matrix, between and above the asci. Asci 71–89 × 8–10 μm (\( \bar{x} \) = 82 × 9 μm, n = 15), 8-spored, bitunicate, fissitunicate, cylindric-clavate, with furcate or knob-like pedicel, rounded at the apex with a minute ocular chamber. Ascospores 19–22 × 3–4 μm diam. (\( \bar{x} \) = 21 × 3.5 μm, n = 30), uni to biseriate, partially overlapping, hyaline, fusiform to cylindrical or ellipsoidal-fusiform, straight to curved, widest at the centre and tapering towards the ends, 3-septate, constricted at the primary septum, smooth-walled, filled with two different sized guttules per cell and surrounded by a mucilaginous sheath. Asexual morph Undetermined.

GenBank Numbers LSU:KY548097; SSU:KY548098; ITS:KY548099.

Culture characteristics: Ascospores germinating on WA within 24 h. Colonies growing on MEA, reaching 5 mm diam. in 1 week at 18 °C. Mycelium superficial, slightly effuse, ashy white, inner brown, sparsely hairy, with undulate edge, lower surface black.

Notes: Angustimassarina alni fits with generic concept of Angustimassarina (Thambugala et al. 2015a). Angustimassarina alni forms a sister clade with Exosporium stylobatum (CBS 16030; asexual morph) and A. premilcurensis (MFLUCC 15-0074. We could not obtain an asexual morph in culture. Angustimassarina alni is similar to A. premilcurensis in having immersed to semi-immersed ascomata, cylindrical to clavate asci and hyaline, fusiform to cylindrical ascospores with a mucilaginous sheath, but differs in having a carbonaceous peridium and different sized ascospores with guttules.

Notes: Angustimassarina premilcurensis differs from other species in Angustimassarina in possessing 1-septate ascospores, constricted and swollen near the septum. In the phylogenetic analyses, A. premilcurensis clustered with Exosporium stylobatum. Exosporium is a hyphomycete (Crous et al. 2011) with more than 120 epithets (Index Fungorum 2017), but DNA sequence data are not available for its type species (Thambugala et al. 2015a). Any conclusive association between A. premilcurensis and Exosporium stylobatum is premature until further DNA sequence data becomes available.

Notes: Angustimassarina italica is phylogenetically closely related to A. acerina and A. quercicola (Fig. 14). However, it differs in having hyaline, 1-septate ascospores while A. quercicola has brown, 1(–3)-septate ascospores, which are finely verruculose at maturity and A. acerina has brown, 1(–3)-septate ascospores (Thambugala et al. 2015a).

Biatrosporaceae K.D. Hyde

Jaklitsch and Voglmayr (2016) dismissed the family Biatriosporaceae, whose type clustered amongst Nigrograna species, and transferred several species from Biatriospora to Nigrograna. They introduced the family Nigrogranaceae and accepted a single genus Nigrograna based on morphology and phylogenetic analyses and provided DNA sequence data. Jaklitsch and Voglmayr (2016) doubted the validity of the strain of B. marina in GenBank. However, based on the type species, the family Biatriosporaceae is morphologically distinct and the family should be maintained. Nevertheless, we accept that it seems odd that the strain of Biatriospora marina in GenBank clusters with Nigrograna species and thus B. marina needs recollecting for sequence analysis to establish if Nigrograna is related, which morphologically seems unlikely. A phylogenetic tree for Nigrogranaceae is presented in this paper (Fig. 59), where the continued use of Biatriosporaceae, which is unlike Nigrogranaceae based on its morphological distinctiveness, is recommended.

Lophiostomataceae Sacc.

The family Lophiostomataceae is an interesting and diverse family in the order Pleosporales, Dothideomycetes. Most members of this family are saprobic and occur mainly on twigs, stems or bark of various woody plants and herbaceous plants in both terrestrial and aquatic environments (Hirayama and Tanaka 2011; Hyde et al. 2013; Ariyawansa et al. 2015c; Thambugala et al. 2015a). Thambugala et al. (2015a) revised the family and accepted 16 genera, including eleven newly introduced genera. In this study, we place two new species and two new host records in Lophiostomataceae (Figs. 14, 20).

Berkleasmium Zobel.

Zobel (1854) established the genus Berkleasmium by re-combining the species Sporidesmium concinnum Berk., and renamed the taxon in honour of Corda, as Berkleasmium cordeanum. Hughes (1958) later corrected this type species name as Berkleasmium concinnum. Moore (1958) and Ellis (1971) accepted this genus for sporodochial taxa that produce dark dictyosporous conidia on short simple unbranched conidiophores or directly on the hyphae. Fourty species are currently listed as legitimate under Berkleasmium in MycoBank (2017). According to Seifertk et al. (2011) the genus Berkleasmium comprises 32 valid species recorded from Africa, Asia, Australasia and North America. Most of these species are recorded from dead substrates, such as dead wood, litter and bark of various plants (Moore 1958; Rao and Rao 1963; Ellis 1971, 1976; Morris 1972; Chouhan and Panwar 1980; Matsushima 1981, 1983; Holubová-Jechová 1987; Yip 1988; Bussaban et al. 2001; Pinnoi et al. 2007; Qu et al. 2014; Hüseyin et al. 2014). The new species B. ariense from India is similar to the type species B. concinnum, however, the conidia are longer. Three species of Berkleasmium were previously recorded from India; B. abuense (current name: Monodictys abuensis), B. osmaniae and B. papillatum (current name: Acrodictys papillata). Phylogenetic affinities of the new taxon with other Berkleasmium species, based on the LSU and ITS gene sequences, is shown in Fig. 20.

Platystomum Trevis.

Platystomum was introduced by Trevisan (1877) and is typified by Platystomum compressum. Platystomum compressum was reported as a synonym of Lophiostoma compressum and Thambugala et al. (2015a) accepted Platystomum in Lophiostomataceae as a distinct genus, and accepted five species (Platystomum actinidiae, P. compressum, P. crataegi, P. rosae and P. salicicola), based on new collections and combinations (Fig. 14).

Notes: Our new isolate is morphologically similar and phylogenetically related to Platystomum rosae (strain MFLUCC 15-0633), but associated with a different host. Platystomum rosae (holotype) was recorded on Rosa canina L (Rosaceae), while our collection was found on Cornus sp. (Cornaceae). The phylogenetic placement of this species is shown in Fig. 14.

Sigarispora Thambug. & K.D. Hyde.

Thambugala et al. (2015a) introduced the genus in Lophiostomataceae and it is typified by S. ravennica (Tibpromma et al.) Thambugala & K.D. Hyde. Sigarispora is characterized by immersed to semi-immersed ascomata, a small crest-like ostiole, and brown, cigar-shaped or ellipsoidal-fusiform, multi-septate or muriform ascospores. Seven species are accepted in the genus.

Material examined: ITALY, Forlì-Cesena Province, near Premilcuore, on dead stem of Helichrysum italicum (Asteraceae), 24 May 2013, Erio Camporesi, IT1302 (MFLU 14-0676, holotype); ex-type living culture, MFLUCC 13-0744); Ibid. (HKAS 94549 bis, paratype).

GenBank Numbers LSU:KY496719; ITS:KY496740; SSU:KY501110.

Notes: The new species clearly differs from other Sigarispora species in having semi-immersed ascomata, cylindric-clavate asci and ellipsoidal, muriform ascospores, with 5–8 transverse septa and 2–3 longitudinal septa. This species separates from other Sigarispora species in the phylogenetic analyses (Fig. 14). Sigarispora coronillae and S. muriformis have muriform ascospores, but S. coronillae differs from S. muriformis in having brown to dark brown ascospores with 4–6 transverse septa and 2–4 longitudinal septa (Thambugala et al. 2015a).

Vaginatispora K.D. Hyde

Vaginatispora was introduced by Hyde (1995) in Massarinaceae Munk to accommodate Vaginatispora aquatica K.D. Hyde. Vaginatispora was long considered to be a synonym of Massarina (Hyde et al. 1992; Read et al. 1997) but recently Thambugala et al. (2015a) confirmed it as a separate genus in Lophiostomataceae based on both morphological characteristics and phylogeny. Vaginatispora is characterized by ‘depressed globose ascomata, immersed beneath a blackened neck, with a slot-like ostiole, numerous and filamentous pseudoparaphyses, cylindrical to clavate asci and narrowly ellipsoidal, hyaline, 2-celled ascospore with a mucilaginous collar around its equator and a spreading papilionaceous sheath’ (Hyde 1995; Zhang et al. 2014). Currently the genus comprises Vaginatispora appendiculata, V. aquatica, V, armatispora and V. fuckelii.

Necks 70–90 µm long, 30–50 µm diam., long slot-like, black, filled with dark brown cells. Peridium 9–12 µm wide at the base, 30–40 µm wide at the sides, comprising 3–4 layers, fused at the outside with the host tissue, composed of thick-walled reddish-brown to dark angular or relatively compressed pseudoparenchymatous cells. Hamathecium of 1–1.5 µm wide, filiform, septate, anastomosing, branched, pseudoparaphyses. Asci 115–130 × 14–18 µm (\( \bar{x} \) = 123.6 × 15.19 µm, n = 20), 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-obclavate, short pedicellate, apically rounded.

Material examined: THAILAND, Chiang Rai Province, Chiang Sean, on dead Calamus rotang stem (Arecaceae), 21 September 2013, Dhanushka Wanasinghe, DHA17 (MFLU 16-2887, new host record); living culture, MFLUCC 13-0835.

GenBank Numbers LSU:KY264745; SSU:KY264749 (Fig. 25).

Notes: As morphological characters examined largely overlap with those of Vaginatispora appendiculata, we report our collection as a new host record of V. appendiculata from Calamus rotang in Thailand. Combined multi-gene based phylogenies also show that both strains (MFLUCC 13-0835 and MFLUCC 11-0083) of V. appendiculata cluster together, but with a low bootstrap support (Fig. 14).

Lophiotremataceae K. Hiray. & Kaz. Tanaka.

Hirayama and Tanaka (2011) introduced the family Lophiotremataceae with its type genus Lophiotrema Sacc. Phylogenetic analyses based on LSU and SSU sequence data supported this new familial placement and its distinctiveness from Lophiostomataceae. Lophiotremataceae comprises Aquasubmersa, Hermatomyces and Lophiotrema (Hyde et al. 2016; Doilom et al. 2017). The genus Hermatomyces was introduced by Spegazzini (1911), with H. tucumanensis as the type species and includes 13 species (Index Fungorum 2017). Morphologically, the genus is characterized by lenticular to cylindrical, muriform conidia, often with subhyaline to pale brown peripheral cells, and dark brown central cells. Conidia are cylindrical and comprise 1–4 columns with 2–11 cells and are irregularly pigmented (Castañeda and Heredia 2000; Leão-Ferreira et al. 2013; Doilom et al. 2017).

Lophiotrema Sacc.

Lophiotrema was proposed by Saccardo (1878) to accommodate species having hyaline ascospores and typified by Lophiotrema nucula, which was excluded from Lophiostoma based on ascospore characteristics. This genus includes many lignicolous bitunicate fungi characterized by immersed-erumpent through woody substrates, dark-pigmented ascomata with ostiolate papilla and fusiform, 1-septate and hyaline ascospores (Barr 1992; Tang et al. 2003; Hirayama and Tanaka 2011). Currently, 161 epithets are listed in Index Fungorum, but only 97 species were accepted in Lophiotrema based on current morphological data and phylogenetic evidence (Hyde et al. 2016; Doilom et al. 2017).

(\( \bar{x} \) = 124 × 37 µm, n = 5), plugged by periphyses, apically with a crest-like papilla, dark, carbonaceous, fragile, with irregular opening. Peridium 23–38.5 µm wide, outer layer narrow, composed of dark cells of textura angularis, inner layer of light pigmented to hyaline cells of textura subglobosa. Hamathecium comprising 1–2 µm wide, branched, septate, cylindrical pseudoparaphyses. Asci (78-)90–125 × 8–11.5 µm (\( \bar{x} \) = 96.5 × 9 µm, n = 20), 8-spored, bitunicate, fissitunicate, cylindric-clavate, sessile to short pedicellate, apically rounded with an ocular chamber. Ascospores 23–29 × 4–6 µm (\( \bar{x} \) = 26 × 5 µm, n = 10), uniseriate, ellipsoidal to broadly fusiform, 1-septate, constricted at the septum, with 1–2 guttules, with distinct large guttules in each cell, with terminal appendages, hyaline, smooth-walled. Asexual morph Undetermined.

Culture characteristics: Ascospore germinating on MEA within 12 h. Colonies on MEA reaching 10 mm diam. in 7 days at 28 °C, flat to slightly effuse, entire edge, dark brown.

Notes: Lophiotrema guttulata differs from other species of Lophiotrema in having a protruding ascomatal neck, carbonaceous papilla and lacking a mucilaginous sheath in the ascospores. Phylogenetic analyses of the combined LSU and SSU dataset reveal that L. guttulata is nested independently between L. lignicola and L. neohysterioides and therefore provides evidence to support our new species (Fig. 25).

Material examined: ITALY, near San Benedetto in Alpe, on dead stem of Sambucus ebulus (Adoxaceae), 24 October 2014, Erio Camporesi, IT2196 (MFLU 15-1497, new host record); living culture MFLUCC 15-0081, (HKAS 94608 bis).

GenBank Numbers LSU:KY496737; ITS:KY496757; SSU:KY501125; TEF1:KY514401.

Notes: Lophiotrema vagabundum was introduced by Saccardo (1878), based on a sexual morph and was recorded from Vitis coignetiae, Epilobium angustifolium and woody plants. Based on rDNA phylogenetic analyses, the collection of L. vagabundum in this study (MFLUCC 15-0081) clustered with high statistical support to other L. vagabundum strains analyzed (Fig. 25). Morphological characters are also identical to other L. vagabundum strains and therefore we report this collection as a new host record on Sambucus ebulus (Adoxaceae), from Italy.

Hermatomyces Speg.

The genus Hermatomyces was introduced by Spegazzini (1911), with H. tucumanensis as the type species. Currently the genus contains six species (Index Fungorum 2017). Morphologically, the genus is characterized by having lenticular to cylindrical, muriform conidia, often with subhyaline to pale brown peripheral cells, and dark brown central cells. Conidia are cylindrical and comprise 1–4 columns with 2–11 cells and are irregularly pigmented (Castañeda and Heredia 2000; Leão-Ferreira et al. 2013; Doilom et al. 2017). Based on the phylogenetic study by Doilom et al. (2017), Hermatomyces is accommodated in Lophiotremataceae.

Etymology: refers to the Sai Khu waterfall where the fungus was collected.

Holotype: MFLU 16-1931

Saprobic on dead stem of Chromolaena odorata Linn. Sexual morph Undetermined. Asexual morph Colonies on natural substrate dry, blackish-brown, velvety, circular, doughnut-shaped, dull, consisting of a sterile mycelial outer zone and a round, glistening, abundantly sporulating centre, with conidia readily liberated when agitated. Mycelium 1.3–2.1 μm wide, superficial, composed of a network of branched, septate, brown, thick-walled, smooth hyphae. Conidiophores 3–4.3 μm long × 1.8–1.9 μm wide (\( \bar{x} \) = 3.6 × 1.8 µm, n = 10), micronematous, flexuous, pale brown, smooth, unbranched, arising from prostrate hyphae at the centre of circular colony. Conidiogenous cells holoblastic, monoblastic, integrated, terminal, cylindrical, hyaline to subhyaline. Conidia 9.2–10.4 µm high × 10.2–11.5 µm wide (\( \bar{x} \) = 9.7 × 10.7 µm, n = 20) monomorphic, thick-walled, smooth, disk-shaped, with central cells dark brown to black, with peripheral cells pale brown.

Colonies growing on PDA, reaching 5 cm in 14 days at 30 °C, mycelium partly superficial, partly immersed, slightly effuse, cottony, with regular edge, olivaceous-green to grayish-green; sexual or asexual spores not formed within 60 days.

Material examined: THAILAND, Chiang Rai Province, Doi Pui, on a dead (not land) stem of Chromolaena odorata (Asteraceae), 5 October 2016, Junfu Li, DPK4 (MFLU 16-2931, holotype). ex-type living culture MFLUCC 16-2818, KUMCC (paratype in HKAS).

GenBank Number LSU:KY559393.

Notes: Morphologically, Hermatomyces chromolaenae is similar to H. saikhuensis in having dark coloured conidia and conidiophores arising from prostrate hyphae at the centre of a circular colony. However, H. chromolaenae is unique in having darker peripheral cells and smaller conidia and the phylogeny also segregates these two species. A close phylogenetic association, albeit with moderate support, between H. chromolaenae and H. pandanicola is also noted. Hermatomyces pandanicola, however, has dark brown to black central cells in the conidia, with subhyaline to pale brown peripheral cells, and in lateral view obovoid, guttulate, hyaline to light brown at lower and upper ends and dark brown at the central cells.

Melanommataceae G. Winter.

The family Melanommataceae, typified by Melanomma, was established by Winter (1885) to accommodate Bertia, Bombardia, Crotonocarpia, Rosellinia, Melanomma and Melanopsamma. Melanommataceae is characterized by globose or depressed perithecial ascomata, bitunicate and fissitunicate asci, pigmented and phragmosporous ascospore (Tian et al. 2015). Tian et al. (2015) revised this family by combining morphology and multi-locus phylogenetic analyses using LSU, SSU, TEF1 and RPB2 datasets and 20 genera were accepted in the family.

Melanomma Nitschke ex Fuckel

Melanomma was validly published by Fuckel (1870) and is typified by Melanomma pulvis-pyrius (Pers.) Fuckel. Melanomma is characterized by the carbonaceous ascomata, and hyaline or brown, 2–3-septate ascospores (Tian et al. 2015). Asexual morphs of Melanomma were reported as coelomycetous and hyphomycetous (Hyde et al. 2011). In this study, we transfer Aposphaeria populina Died. into Melanomma.

Basionym: Aposphaeria populina Died., Krypt.-Fl. Brandenburg (Leipzig) 9: 206 (1912)

Notes: Aposphaeria is considered as an asexual genus in the family Melanommataceae. Tian et al. (2015) mentioned Aposphaeria and phoma-like asexual morphs have been reported for Melanomma species (Sivanesan 1984). Additionally, this study reports the sexual state for Aposphaeria; A. corallinolutea based on multi-gene phylogeny and the identity of the asexual morph produced from culture. Diedicke (1912) introduced A. populina as a phoma-like species reported from Populus canadensis. De Gruyter et al. (2013) designed an epitype from the same host, and generated sequences for A. populina. Based on phylogenies, A. populina is related to Melanomma pulvis-pyrius as they clustered together with high statistical support (Tian et al. 2015; Hyde et al. 2016). Given that the sexual morph morphology in A. corallinolutea and M. pulvis-pyrius are different (Mugambi and Huhndorf 2009), and phylogeny refer them to distinct clades, we synonymize Aposphaeria populina under Melanomma populina.

Aposphaeria Sacc.

The genus Aposphaeria was introduced by Saccardo (1880) and has a phoma-like structure. Aposphaeria is characterized by pycnidial, superficial conidioma, hyaline, short conidiophores, enteroblastic, phialidic, discrete, conidiogenous cells, and hyaline, aseptate, and ellipsoidal conidia (Sutton 1980). Tian et al. (2015) reconsidered the family Melanommataceae and as a result of lack of sequence data for A. pulviscula (Sacc.) Sacc (the type species), Aposphaeria was retained in Melanommataceae. Based on the phylogenetic analysis, A. populina is closely related to Melanomma pulvis-pyrius, the type genus of Melanommataceae (82%ML/82%MP/0.90BYPP, Fig. 31) and is a synonym of Melanomma. It is however, important that the type of Aposphaeria is recollected to establish if the genus sensu stricto, belongs in Melanommataceae. In this study, we describe the sexual morph of Aposphaeria corallinolutea, bearing in mind that Aposphaeria sensu stricto may not belong in Melanommataceae.

Notes: Aposphaeria corallinolutea was introduced by De Gruyter et al. (2013) based on Pleurophoma sp. cultures in CBS culture collection. Aposphaeria corallinolutea (MFLUCC 16-1059, sexual morph) has characters similar to Melanommataceae such as nearly superficial and carbonaceous ascomata, papillate ostioles, thick-walled peridium, trabeculate pseudoparaphyses, cylindrical uniseriate asci, and 1-septate ascospores. Our collection also produced an asexual morph in culture, which is very similar to the characteristics of A. corallinolutea (CBS 131286, CBS 131286). On the other hand, A. corallinolutea strains are sister taxa to Melanomma but lack support. In the phylogenetic tree, our strain Aposphaeria corallinolutea (MFLUCC 16-1059) clustered together with A. corallinolutea (CBS 131286, CBS 131286) (Fig. 31) and we describe the sexual morph of A. corallinolutea with the support of asexual morph production from culture.

Nigrogranaceae Jaklitsch & Voglmayr

See notes under Biatriosporaceae.

Nigrograna De Gruyter et al.

Nigrograna was described by De Gruyter et al. (2013) as a monotypic genus with Nigrograna mackinnonii as type species. The sexual morph of Nigrograna is characterized by depressed globose to globose, immersed or superficial, black ascomata, ostioles periphysate, Ascospores asymmetric, fusoid to narrowly ellipsoid with the second cell slightly wider than others (Jaklitsch and Voglmayr 2016). The asexual morph of Nigrograna is characterized by pycnidia similar to ascomata and usually co-occurring with them, filiform conidiophores, simple to sparsely branched. Conidia forming on pegs and phialides, oblong, 1-celled, smooth (Jaklitsch and Voglmayr 2016). Five species are accepted in Nigrograna (Jaklitsch and Voglmayr 2016) (Fig. 33).

GenBank Numbers LSU:KY511064; SSU:KY511065; ITS:KY511063; TEF1:KY511066.

Notes: All species of Nigrograna are morphologically very similar and thus, Jaklitsch and Voglmayr (2016) considered them to be cryptic species. Morphologically, N. cangshanensis is very similar to other species in the genus. However, N. cangshanensis differs from N. fuscidula, N. norvegica and N. obliqua in having a thicker peridium. Phylogenetic analysis also showed that N. cangshanensis is distinct from other Nigrograna species (Fig. 33).

Roussoellaceae J.K. Liu, Phook., D.Q. Dai & K.D. Hyde

The family Thyridariaceae was introduced by Hyde et al. (2013) to accommodate the genus Thyridaria based on morphology and phylogenetic analyses with Thyridaria incrustans as the type species. Jaklitsch and Voglmayr (2016) introduced a new genus, Parathyridaria, with two species in the family, and provided a phylogenetic analysis of the family based on the combined ITS, LSU, SSU, RPB2 and EF-1α sequence data. In this study, a new species, Parathyridaria robiniae, is introduced with evidence from molecular data analysis and morphological comparisons. Jaklitsch and Voglmayr (2016) treated Roussoellaceae as a synonym of Thyridariaceae. We obtained a similar topology in our phylogenetic analysis, however, the two families have distinct morphological characters. The families are also well resolved in the analyses. This is in agreement with the results of Liu et al. (2014) where they provide evidence that Roussoellaceae is a good family in Pleosporales with high diversity (Crous et al. 2014; Ariyawansa et al. 2015b; Dai et al. 2017). We follow Liu et al. (2014) and treat Roussoellaceae as a well-resolved family in Pleosporales. The phylogenetic tree, based on combined LSU, ITS, EF-1α and RPB2 sequence data is presented in Fig. 35.

GenBank Numbers LSU:KY511141; ITS:KY511142; TEF1:KY549682.

Notes: Phylogenetic analysis indicates that our collection belongs to the family Thyridariaceae and P. robiniae groups together with members of Parathyridaria a genus that was introduced by Jaklitsch and Voglmayr (2016). The phylogeny also indicates that P. robiniae lies in an independent terminal taxon nested between P. percutanea and P. ramulicola and therefore can be considered as a new species (Fig. 35). Parathyridaria robiniae is also distinct in having 1-septate ascospores surrounded by a hyaline gelatinous sheath.

Massarineae

Massarineae is a suborder of Pleosporales, originally established by Barr (1979) to accommodate Massarinaceae and Arthopyreniaceae (Hawksworth et al. 1983, 1995; Barr 1987; Eriksson and Winka 1998; Kirk et al. 2008; Lumbsch and Huhndorf 2010). The taxonomic framework, phylogenetic relationships, biology, and species diversity of Massarineae are poorly understood (Tanaka et al. 2015; Phukhamsakda et al. 2016).

Didymosphaeriaceae Munk.

The family Didymosphaeriaceae was introduced by Munk (1953) and typified by Didymosphaeria, with D. epidermidis (Fr.) Fuckel as the type species. Ariyawansa et al. (2014a) synonymized Montagnulaceae under Didymosphaeriaceae based on priority of the oldest name. Currently, 25 genera are accommodated in Didymosphaeriaceae (Ariyawansa et al. 2015b; Crous et al. 2015a; Thambugala et al. 2014a; Wijayawardene et al. 2014a; Tanaka et al. 2015; Wanasinghe et al. 2016). We introduce introduce a new species of Paraphaeosphaeria with an updated phylogenetic tree for the family.

Paraphaeosphaeria O.E. Erikss.

Paraphaeosphaeria was introduced by Erikss (1967) and species of this genus are similar to Phaeosphaeria Miyake 1909. Sutton (1980) mentioned that all known species of Paraphaeosphaeria occur on monocotyledons and taxa differ in ascomatal structure, ascospores septation, size, host and in asexual characteristics. Taxonomic studies have also reported that this genus is polyphyletic (Câmara et al. 2002; Checa et al. 2002)

Paraphaeosphaeria viciae de Silva, Camporesi & K.D. Hyde, sp. nov.

GenBank Numbers LSU:KY397948; SSU:KY397947; ITS:KY379969.

Notes: Paraphaeosphaeria viciae shares some similarities with P. spartii in having subglobose to ellipsoid or obovoid, aseptate conidia with guttules. Paraphaeosphaeria viciae however, has 113–163 μm diam., semi-immersed, globose to subglobose conidiomata as compared to 200–300 μm diam. in P. spartii (Liu et al. 2015; Wijayawardene et al. 2016). DNA sequence analyses confirm the position of our new taxon in Didymosphaeriaceae (Fig. 37) and indicate the genus is polyphyletic.

Latoruaceae Crous

The family Latoruaceae was introduced by Crous et al. (2015b) and typified by Latorua caligans (Bat. & H.P. Upadhyay) Crous. Four genera Latorua, Matsushimamyces, Polyschema, Pseudoasteromassaria are accommodated in this family. Both sexual morph and asexual morph of the genus Pseudoasteromassaria have been reported and are characterized by fusiform, 1–3-septate, brown ascospores and cylindrical, 6–7-septate, hyaline conidia (Ariyawansa et al. 2015c) (Fig. 39).

Pseudoasteromassaria M. Matsum. & Kaz. Tanaka

Pseudoasteromassaria was introduced by M. Matsum. & Kaz. Tanaka (2015) with Ps. fagi M. Matsum. & Kaz. Tanaka as the type species. The morphological characteristics of this genus are similar to those of Asteromassaria (Pleomassariaceae) (Ariyawansa et al. 2015c).

GenBank Numbers LSU:KY522724; SSU:KY522725; ITS:KY522726.

Notes: Phylogenetic analyses of combined genes indicate that Pseudoasteromassaria spadicea clustered with other species of Pseudoasteromassaria and in particular it shares a close affinity to P. fagi. Pseudoasteromassaria spadicea differs from the asexual strain of P. fagi mainly by its globose or obovoid, aseptate conidia and conidial size (11–15 × 7–10 μm vs. (52–)61–71 × 10–12.5 μm) (Ariyawansa et al. 2015c).

Lentitheciaceae Y. Zhang ter, C.L. Schoch, J. Fourn., Crous & K.D. Hyde

The family Lentitheciaceae was introduced by Zhang et al. (2009a) with L. fluviatile (Aptroot & Van Ryck.) K.D. Hyde (2009) as the type species. This family now includes six genera (Wanasinghe et al. 2014).

Keissleriella Höhn.

Keissleriella was introduced by Höhnel (1919) to accommodate Keissleriella aesculi Sacc. (≡Pyrenochaeta aesculi Höhn.) as the type. The genus is characterized by ascomata with ostiolar necks filled with black setae, and 1 to multi-septate, hyaline ascospores (Barr 1990; Liu et al. 2015). Munk (1957) placed the genus in Lophiostomataceae, while von Arx and Muller (1975) placed it in Pleosporaceae. Later Barr (1990) transferred it to Melanommataceae. Lumbsch and Huhndorf (2007) maintained Keissleriella in Massarinaceae, while Zhang et al. (2009b) placed the genus in Lentitheciaceae, and this has been followed by subsequent authors (Hyde et al. 2013; Tanaka et al. 2015; Wijayawardene et al. 2014a; Zhang et al. 2012b) (Fig. 41).

Notes: Keissleriella cirsii is typical of Keissleriella in its ostiolar neck covered by short dark setae (Munk 1953; Tanaka et al. 2015)., K. cirsii is a distinct species in the genus, supported by molecular and morphological characteristics. Keissleriella cirsii clustered as sister to K. taminensis with 100% bootstrap support. Keissleriella cirsii differs from K. taminensis in having larger ascomata and ascospores with fewer longitudinal septa (3–4 vs. 4–5) (Tanaka et al. 2015).

Pleurophoma Höhn.

The genus Pleurophoma, based on P. pleurospora (De Gruyter et al. 2009), lacks any known sexual morph (De Gruyter et al. 2010). We introduce a new species of Pleurophoma italica, and describe both morphs.

GenBank Numbers LSU:KY496734; ITS:KY496754; SSU:KY501122; TEF1:KY514398.

Notes: Pleurophoma italica is introduced as a new species with both sexual and asexual morphs. The phylogeny indicates a close relationship of P. italica to P. pleurospora (type species), but constitutes a separate branch (Fig. 41). Pleurophoma italica shares similar asexual morphology with P. pleurospora. However, our taxon also clustered with Keissleriella sparticola, K. cladophila and K. genistae, but the morphological characteristics of sexual morphs are different. In the future, if Keissleriella sparticola, K. cladophila and K. genistae asexual morphs are discovered, and with more phylogenetic evidence, these three species could be synonymized under Pleurophoma. Hence, based on our phylogenetic tree (Fig. 41) we agree with Crous et al. (2015a) that the link between Pleurophoma and Keissleriella needs to be resolved.

Material examined: ITALY, Forlì-Cesena, Ravaldino in Monte, on dead Arundo donax stem (Poaceae), 11 November 2014, Erio Camporesi, IT 2233 (MFLU 15-1360, new host record);

GenBank Numbers LSU:KY264748; ITS:KY264744; SSU:KY264752.

Notes: Li et al. (2016) introduced Pseudodidymosphaeria phlei from Phleum pretense L. (Poaceae) collected in Forlì-Cesena Province of Italy as the second species of Pseudodidymosphaeria. Pseudodidymosphaeria phlei is similar to type species, P. spartii, in having globose to subglobose ascomata, cylindric-clavate asci and 1-septate ascospores. Our new isolate is also morphologically similar to P. phlei (strain MFLUCC 14-1061) and phylogenetically groups with 100% ML support. However, it is associated with a different host. Pseudodidymosphaeria phlei (holotype) was recorded on Phleum pretense and our collection was found on Arundo donax (Poaceae).

Massarineae genera incertae sedis

Inflatispora Y. Zhang ter, J. Fourn. & K.D. Hyde

Zhang et al. (2011) introduced Inflatispora as a lignicolous genus of Pleosporales from France to accommodate I. pseudostromatica Y. Zhang ter, J. Fourn. & K.D. Hyde. The genus is characterized by ‘widely porate ascomata, bitunicate asci, 3-septate, hyaline, cylindrical ascospores, with a swollen upper central cell and surrounded by a thin sheath, and narrow cellular pseudoparaphyses that anastomose between and above the asci (Zhang et al. 2011). Inflatispora pseudostromatica resembles species of Nodulosphaeria in having ascospores with an enlarged supramedian cell, but it can be distinguished from Nodulosphaeria by the presence a sheath surrounding the whole ascospore, while Nodulosphaeria has terminal ascospore appendages. The genus Inflatispora seems more typical of Massarineae, but the familial placement is still uncertain. Thus, we maintain the genus in Massarineae genera incertae sedis. It is essential to collect more taxa to establish their placement in Massarineae (Fig. 39).

Notes: We introduce the second species in Inflatispora, I. caryotae from Thailand based on morphological characteristics coupled with molecular data (Fig. 39). This species morphologically resembles I. pseudostromatica in having fusiform, hyaline ascospores with acute ends and a distinct mucilaginous sheath surrounding the ascospores. However, I. pseudostromatica has semi-immersed ascomata and 3-septate ascospores, while I. caryotae has immersed ascomata and 1-septate ascospores.

Suborder Pleosporineae

Didymellaceae Gruyter, Aveskamp & Verkley

The family Didymellaceae was introduced for the “Didymella clade” to accommodate the type species Didymella exigua and includes phoma and phoma-like genera (De Gruyter et al. 2009). Seventeen genera are presently included in Didymellaceae based on morphology and phylogeny, and these are Allophoma, Ascochyta, Boeremia, Calophoma, Dactuliochaeta, Didymella, Epicoccum, Heterophoma, Leptosphaerulina, Macroventuria, Neodidymelliopsis, Neoascochyta, Nothophoma, Paraboeremia, Phoma, Phomatodes and Xenodidymella (Hyde et al. 2013; Wijayawardene et al. 2014a; Chen et al. 2015). We provide an updated tree for Didymellaceae.

Ascochyta Lib

Ascochyta was introduced by Lib. in (1830) with A. pisi as the type species. A recent study by Aveskamp et al. (2010), reported that Ascochyta is polyphyletic. We introduce two new species and one new host record of Ascochyta and provide a new phylogenetic tree for Didymellaceae (Fig. 47).

Notes: Ascochyta rosae is introduced with both sexual and asexual morphs. The phylogeny indicates that A. rosae clusters with A. herbicola with high statistical support (100% in ML/1.00 in BYPP) (Fig. 47). Ascochyta rosae and A. herbicola differ in the sizes of conidiomata and conidia morphology. Conidia of A. rosae are smaller than A. herbicola (3.2–4.4 × 1.2–1.8 vs. 7–10.5 × 2–2.5) and the conidia are cylindrical to subcylindrical, without guttules (De Gruyter et al. 1998) while, A. rosae has cylindrical, sometimes slightly curved conidia with guttules. RPB2 nucleotide sequence comparison reveals six base pair differences with Ascochyta herbicola.

Calophoma Q. Chen & L. Cai

Calophoma was introduced by Chen & Cai (2015) with C. clematidina (Thüm.) Q. Chen & L. Cai as the type species. The asexual morph of this genus is characterized by subglobose, subcylindrical, ellipsoidal, somewhat obclavate-fusiform conidia with 0–1-septa and chlamydospores are produced in one species. The sexual morph of this genus has not been reported (Chen et al. 2015).

Notes: Calophoma petasitis is introduced as a new species with the first report of a sexual morph for this genus. The sexual morph of C. petasitis is characterized by subglobose ascomata and smooth-walled, guttulate, hyaline ascospores lacking a mucilaginous sheath. Multigene phylogenetic analyses support the position of the new taxon in Calophoma and its establishment as a new species. Calophoma petasitisi clearly segregates from other known species (Fig. 47). We attempted to induce the asexual morph of this species on WA media and found that they produce ascomata on media.

Didysimulans Tibpromma, Camporesi & K.D. Hyde, gen. nov.

Type species: Didysimulans mezzanensis Tibpromma, Camporesi & K.D. Hyde

Saprobic on dead stems. Sexual morph immersed under the host tissue, solitary, black, globose to irregular, conspicuous at the surface, with or lacking ostioles. Peridium composed of brown cells arranged in a textura angularis. Hamathecium comprising dense, septate, guttulate pseudoparaphyses. Asci 8-spored, bitunicate, cylindrical, slightly curved, short pedicellate, apically rounded. Ascospores 2-celled, hyaline, 1-septate, guttulate, enlarged at the first cell, constricted at the septum, conical at the ends, lacking a mucilaginous sheath. Asexual morph Chlamydospores occasionally produced, hyaline to yellow–brown mycelium, in spiral chains.

Notes: Didysimulans is introduced as a new genus based on morphology and phylogenetic support (LSU, ITS, RPB2 and β-tubulin DNA sequence data). The ascomata of Didysimulans are similar to those of Didymellaceae in having a peridium of textura angularis and cylindrical asci with 2-celled, hyaline, 1-septate ascospores. Didysimulans produces chlamydospores with hyaline to yellow–brown mycelium, with spiral chains. Leptosphaerulina (muriform ascospores), Platychora (ascospores septate near the lower end), Monascostroma (ascospores narrowly inequilateral), Macroventuria (ascomata with hairs or setae) and Didymella (ovoid to ellipsoidal ascospores) (Hyde et al. 2013), are all easily distinguishable from Didysimulans.

Nothophoma Q. Chen & L. Cai

The genus Nothophoma was introduced with the type species N. infossa (Ellis & Everh.) Q. Chen & L. Cai. (syn. Phoma infossa) to accommodate five synonymized Phoma species, including Nothophoma anigozanthi (Tassi) Q. Chen & L. Cai (syn. Phoma anigozanthi), Nothophoma arachidis-hypogaeae (V.G. Rao) Q. Chen & L. Cai (syn. Phoma arachidis-hypogaeae), Nothophoma quercina (Syd.) Q. Chen & L. Cai (syn. Phoma fungicola), and Nothophoma gossypiicola (Gruyter) Q. Chen & L. Cai (syn. Phoma gossypiicola) (Chen et al. 2015). This genus is ubiquitous, species-rich and includes many important plant pathogens, some of which are of quarantine concern (Aveskamp et al. 2008, 2010; Chen et al. 2015).

GenBank Numbers LSU:KY053897; ITS:KY053896; RPB2: KY053898; β-tubulin: KY053899.

Notes: Nothophoma quercina has been reported as a saprobe from Quercus sp. in Ukraine (Aveskamp et al. 2010; Chen et al. 2015) and as a pathogen causing stem canker and fruit blight on Pistacia vera L. in the USA (Chen et al. 2013). This is the first record of N. quercina on Ulmus species. When comparing our species with the type specimen of N. quercina (CBS 633.92), they are similar in morphology, but differ in their host. The conidiomata are larger, while conidia are smaller compared to the type specimen. Based on our phylogenetic analysis of combined ITS, TEF1, β-tubulin and RPB2 sequence data of Nothophoma species (Fig. 47), our strain (MFLUCC 16-1392) clustered with the ex-type strain of Nothophoma quercina with relatively high bootstrap and Bayesian probabilities (99%MP/1.00BYPP).

Stagonosporopsis Died.

Stagonosporopsis produces dimorphic conidia, and most of these conidia are aseptate, hyaline, ellipsoidal to subglobose, thin-walled and smooth-walled. The other type of conidia are smaller, 1-celled or with up to 3 septa, produced both in vivo and in vitro in the same pycnidium (Chen et al. 2015). Aveskamp et al. (2010) and Chen et al. (2015) have detailed this genus.

GenBank Numbers ITS:KY100872; TEF1:KY100874; β-tubulin:KY100878; RPB2:KY100876.

Notes: Stagonosporopsis species are characterized by their unique dimorphic conidia, chlamydospores and conidiomata (De Gruyter and Noordeloos 1992; Chen et al. 2015). Molecular data is important to identify and characterize these species. Combined phylogenetic analysis of LSU, ITS, β-tubulin and RPB2 sequence data places S. ailanthicola within the clade of Stagonosporopsis in the Phoma species complex. Stagonosporopsis ailanthicola differs from S. dorenboschii in having chlamydospores and larger conidia. It forms a sister taxon with S. heliopsidis with 100% bootstrap support and 1.00 Bayesian posterior probability (Fig. 47). This is the first host record of Stagonosporopsis species on Ailanthus.

Leptosphaeriaceae M.E. Barr

The family Leptosphaeriaceae was introduced by Barr (1987) in the order Pleosporales and is typified by Leptosphaeria doliolum (Pers.) Ces. & De Not. Taxa commonly occur as saprobes or parasites (Hyde et al. 2013). Members of this family are characterized by superficial or erumpent ascomata, with single papillate ostiole lined with periphyses, a relatively thick peridium wall, bitunicate cylindrical asci and pale brown to brown, transversely septate ascospores (Kodsueb et al. 2006; Ariyawansa et al. 2015a). The asexual morphs of the family Leptosphaeriaceae can be coelomycetous or hyphomycetous (Shenoy et al. 2006; Zhang et al. 2012b; De Gruyter et al. 2013; Ariyawansa et al. 2015a). Currently, seven genera are accepted in the family: Alternariaster, Heterospora, Leptosphaeria, Neophaeosphaeria, Paraleptosphaeria, Plenodomus, and Subplenodomus (Ariyawansa et al. 2015a). We introduce a new species in both Paraleptosphaeria and Subplenodomus. Updated phylogenetic analyses followed taxon sampling as outlined by Ariyawansa et al. (2015a) (Fig. 58).

Paraleptosphaeria Gruyter, Aveskamp & Verkley

Paraleptosphaeria is typified by P. nitschkei (Rehm ex G. Winter) Gruyter, Aveskamp and Verkley. De Gruyter et al. (2013) introduced the genus to accommodate the heterogeneous section of Leptosphaeria and its related species in Leptosphaeriaceae. Paraleptosphaeria is characterized by having superficial or immersed, subglobose ascomata, a thick-walled peridium comprising cells of textura angularis, cylindric-clavate asci and transversly septate ascospores. Ariyawansa et al. (2015a) included six species in this genus.

Saprobic on dead and dying branches of Prunus padus L. Sexual morph Ascomata 288–345 μm high × 330–396 μm diam. (\( \bar{x} \) = 316 × 363 μm, n = 5), solitary, scattered or clustered in small groups, immersed under epidermal layer, superficial on host surface, globose, black to dark brown, coriaceous, ostiole central. Ostioles 119 × 83 μm, papillate, shiny, dark brown, smooth, periphyses filling ostiole channel. Peridium 9–53 μm wide, up to 72 μm at base, outer region heavily pigmented, composed of 6–8 layers of textura angularis, black to dark-brown, 7–17(–20) μm wide cells, inner layer composed of thick hyaline gelatinous cells. Hamathecium comprising numerous, 2–3.1 μm (\( \bar{x} \) = 2 μm, n = 50) wide, long, transversely septate, branched, cellular pseudoparaphyses. Asci 74–127 × 8–14 μm (\( \bar{x} \) = 106 × 11 μm, n = 30), 8-spored, bitunicate, broad-cylindrical, with club-shaped pedicel, apically rounded, ocular chamber clearly visible when immature. Ascospores 16–21 × 6–7 μm (\( \bar{x} \) = 18 × 6 μm, n = 50), overlapping biseriate, pale brown, broad-fusiform, conical at the apex, (2)–3 transversely septate, constricted at the septa, enlarged at the second cell from apex, wall rough, indentations present when mature. Asexual morph Undetermined.

Material examined: RUSSIA, Arkhangelsk Region, Arkhangelsk City, near northern Maimaksa urban microdistrict, wood waste landfill, on dead and dying branches of Prunus padus (Rosaceae), 11 May 2015, G.V. Okatov, T-589 (MFLU 15-2756, holotype).

GenBank Numbers LSU:KY554198; SSU:KY554201; ITS:KY554203; TEF1: KY554206.

Notes: Paraleptosphaeria padi is typical of Paraleptosphaeria based on the thick-walled peridium, immersed under host epidermal layer, scleroplectenchymatous cell layers, broad-cylindrical asci with a bulbous pedicel and transversally septate ascospores (Ariyawansa et al. 2015a). We compared the new species with P. praetermissa that has been reported from Rosaceae. Even though P. padi is similar to P. praetermissa in its peridium, asci, and ascospore characteristics; the ascomata of P. praetermissa are erumpent to immersed, whereas in P. padi they are superficial and smaller in size (300–500 μm high × 350–625 μm wide diam. vs. 288–345 μm high × 330–396 μm wide diam.). Paraleptosphaeria padi also shares similarities with P. dryadis. However, P. dryadis has smaller ascomata (180–275 μm high × 150–250 μm wide and larger ascospores (20–25 μm high × 6–7 μm wide diam. The phylogeny also supports the establishment of P. padi as a new species with high support (Fig. 58).

Subplenodomus Gruyter, Aveskamp & Verkley

Subplenodomus was established by De Gruyter et al. (2013), typified with S. violicola (P. Syd.) Gruyter, Aveskamp & Verkley, to accommodate some Phoma-like species that belong to Leptosphaeriaceae. Based on morphological characterization and multi-gene phylogenetic analysis, Subplenodomus are accepted as asexual morphs of Leptosphaeriaceae (De Gruyter et al. 2013; Hyde et al. 2013; Ariyawansa et al. 2015a). The genus includes S. apiicola, S. drobnjacensis, S. valerianae and S. violicola. Subplenodomus is characterized by thick-walled pycnidia, consisting of pseudoparenchymatous or sometimes scleroplectenchymatous cell types, ostiole, phialidic, ampulliform to doliiform conidiogenous cells and hyaline, aseptate, and ellipsoid conidia (De Gruyter et al. 2013). We reconstruct the phylogeny for Leptosphaeriaceae using a concatenated dataset of RPB2 and β-tubulin. Our new collection of S. galicola (MFLU 15-1368) is close to S. violicola (Fig. 59).

Ostioles 70–98 μm high × 98–117 μm diam. (\( \bar{x} \) = 87 × 104 μm, n = 5), papillate, shiny, brown to reddish-brown, smooth, filled with periphyses. Peridium 32–60 μm wide, up to 75 μm at ostiole part, thick, outer region of heavily pigment cells, outer layer of 8–10 layers of black to dark-brown cells of textura angularis, inner layer composed of thick-walled, hyaline, angular cells. Hamathecium comprising numerous, long, 1.5–2.8 μm (\( \bar{x} \) = 2 μm, n = 50) wide, broad, transversely septate, branched, cellular pseudoparaphyses. Asci 66–120 × 12–17 μm (\( \bar{x} \) = 98 × 14 μm, n = 20), 8-spored, bitunicate, broad cylindrical, with club-shaped pedicel, apically rounded, ocular chamber visible when immature. Ascospores 30–40 × 6–9 μm (\( \bar{x} \) = 37 × 7 μm, n = 50), overlapping biseriate, pale brown, broad fusiform, tapering at the ends, with (3)–4 transverse septa, slightly constricted at the septa, enlarged at the second cell from apex, wall rough, indentations present when mature.

Notes: Subplenodomus galicola is similar to other Subplenodomus species in its pseudoparenchymatous peridium cell types (De Gruyter et al. 2013). Subplenodomus galicola also shares similarities with Plenodomus in its cylindric asci and yellowish ascospores with 3–5 transverse septa. However, they are distinct, as the ascomata of S. galicola are, superficial, whereas Plenodomus has immersed to erumpent ascomata (Ariyawansa et al. 2015a). Currently, the species of Subplenodomus are known from herbaceous plants or woody dicotyledonous trees (De Gruyter et al. 2013).

Phaeosphaeriaceae M.E. Barr.

The family Phaeosphaeriaceae, introduced by Barr (1979), was originally characterized by immersed to superficial, globose to subglobose ascomata, short papilla, bitunicate asci and hyaline, yellowish or brown, fusiform to ellipsoidal, filiform, or muriform, septate ascospores (Barr 1979; Shoemaker 1984; Shoemaker and Babcock 1989; Zhang et al. 2012b; Hyde et al. 2013; Phookamsak et al. 2014). Most species in this family are widely distributed on plants as necrotrophic pathogens or as saprobes (Shoemaker and Babcock 1989; Carson 2005; Stukenbrock et al. 2006; Cannon and Kirk 2007). Phaeosphaeriaceae shows diverse morphological characters and comprise more than 35 sexual and asexual genera (Phookamsak et al. 2014; Wijayawardene et al. 2014a; Hyde et al. 2016).

Entodesmium Riess

Entodesmium was introduced by Riess in 1854 with E. rude Riess as the type species. Entodesmium has immersed, globose ascomata, and filiform, multi-septate ascospore, some breaking into part ascospores (Shoemaker 1984; Barr 1992; Zhang et al. 2012b; Phookamsak et al. 2014) (Fig. 61).

Neosetophoma Gruyter, Aveskamp & Verkley

Neosetophoma is typified by N. samararum (Desm.) and most species are pathogens causing leaf spots of various hosts (Phookamsak et al. 2014). The genus is characterized by globose to irregular conidiomata, with papillate ostioles, and yellowish conidia that are attenuate at one end (De Gruyter et al. 2010) and no sexual morph is known.

Notes: The phylogenetic analyses place N. garethjonesii in Neosetophoma as a new species with good statistical support (95% in ML/0.99 in BYPP) (Fig. 61). The sexual morph of Neosetophoma had not been previously reported (De Gruyter et al. 2010, Liu et al. 2015). Neosetophoma garethjonesii is introduced as a new species and is the first report of the sexual morph of Neosetophoma.

Nodulosphaeria Rabenh.

The genus Nodulosphaeria was introduced by Rabenhorst (1858) and typified with N. hirta Rabenh. The characteristics of this genus are ascomata lined with brown setae, and three- to multi-septate ascospores, with a swollen cell and some with terminal appendages (Holm 1961; Shoemaker 1984; Mapook et al. 2016). Clements and Shear (1931) considered Nodulosphaeria a synonym of Leptosphaeria, but Holm (1957) showed Nodulosphaeria was different to Leptosphaeria. Recent studies by Phookamsak et al. (2014), Ariyawansa et al. (2015a) and Mapook et al. (2016) included a reference strain of Nodulosphaeria modesta, morphological characteristics and investigation of the familial placement and generic affinities based on combined DNA sequence data.

Notes: Nodulosphaeria sambuci shares similarities with species having 8-septate ascospores (Nodulosphaeria derasa, N. dolioloides and N. pellita), but those species lack molecular data. It is phylogenetically closely related to N. senecionis with high statistical support (100% in ML, 1.00 in BYPP). However, N. sambuci has fusiform, golden yellow ascospores, that are enlarged at the fourth cell from the apex, and conical and narrowly rounded at the ends, while N. senecionis has long fusiform to almost cylindrical, yellowish brown ascospores, enlarged at the third cell from the apex and tapering towards the rounded ends (Ariyawansa et al. 2015c).

Phaeosphaeria I. Miyake

Phaeosphaeria was established by Miyake (1909) with P. oryzae as the type species. The epitypification of Phaeosphaeria oryzae I. Miyake and Phaeoseptoria papayae Speg. are confirmed through sexual and asexual morph connections and based on evidence from phylogenetic analysis (Quaedvlieg et al. 2013; Phookamsak et al. 2014).There are 203 epithets for Phaeosphaeria in Index Fungorum (2017) with 19, 363 nucleotide sequences available in GenBank.

Notes: Phaeosphaeriopsis yuccae is characterized by having pycnidial conidiomata, doliiform to cylindrical or ampulliform conidiophores and globose to subglobose, dark brown conidia at maturity. Paraphaeosphaeria species differ in their asexual morph characteristics, including conidiomatal structure, type of conidiogenesis, and conidial morphology. Some asexual morphs are Coniothyrium-like, whereas others are more typical of Microsphaeropsis Höhn (Câmara et al. 2003). This new strain is Coniothyrium-like and morphologically most similar to asexual morph of Phaeosphaeriopsis dracaenicola in conidiomata, conidiophores and conidial nature, but they are phylogenetically distant in our phylogram (Fig. 62). According to phylogenetic analyses P. phacidiomorpha has a close affinity to P. yuccae, but the two strains are well-resolved with high statistical support (83% ML, 1.00 BYPP) (Fig. 61). Furthermore, the conidiomata of P. phacidiomorpha is cylindrical, dark brown and 3 mm long and typical of the Microsphaeropsis-like asexual morph of Phaeosphaeriopsis (Farr et al. 2006; Câmara et al. 2003).

Pleosporineae genera incertae sedis

Camarosporium Schulzer

Camarosporium was established by Schulzer (1870), with Camarosporium quaternatum as the type species. The genus Camarosporium has been referred to different families (Liu et al. 2015; Wijayawardene et al. 2014b, c, 2015, 2016; Ariyawansa et al. 2015b). Currently, there are more than 500 names listed in the genus (Index Fungorum 2017). Based on multi-locus phylogeny, Wijayawardene et al. (2014c) placed Camarosporium sensu stricto in Pleosporineae, Pleosporales. This genus has been reported as the asexual morph of many important fungal families and orders including Cucurbitariaceae, Leptosphaeriaceae, Phaeosphaeriaceae and Botryosphaeriales (Kirk et al. 2008; Wijayawardene et al. 2012; Hyde et al. 2013) (Fig. 69).

Notes: Camarosporium uniseriatum clusters with two coelomycetous species, C. clematidis and C. spartii with high bootstrap support (Fig. 69). Camarosporium uniseriatum, C. elongatum and C. arezzoensis, are the sexual morphs reported for the genus Camarosporium (Mirza 1968; Hyde et al. 2013; Tibpromma et al. 2016a; Thambugala et al. 2016). Camarosporium laburnicola differs from C. elongatum and C. arezzoensis in having smaller asci and ascospore with a different number of longitudinal and transverse septa. Even though asci and ascospore sizes overlap, C. laburnicola can be distinguished from C. uniseriatum which has 3–5 transverse septa and 1–2(–3) longitudinal septa; (Thambugala et al. 2016). However, there are three coelomycetous Camarosporium species (i.e. C. cytisi, C. laburni, C. laburnicum) reported from the same host (Laburnum spp.) for which molecular data are unavailable (Saccardo 1882, 1892).

Notes: Based on phylogenetic analyses and morphological comparison, our collection belongs to Camarosporium sensu stricto, which is a distinct lineage in Pleosporinae, Pleosporales. In our phylogenetic analyses of combined LSU, SSU and ITS sequence data of Camarosporium sensu stricto (Fig. 52), our collection of C. moricola clustered in a well-defined monophyletic clade sister to C. robiniicola (MFLUCC 13-0527) and C. aureum (MFLUCC 14-0620) with relatively high bootstrap and Bayesian probabilities (90% MP/97% ML/1.00 BYPP). Camarosporium moricolais distinct from C. robiniicola as the latter has obclavate conidiophores and larger conidia (18–28 × 7–11 μm) with 4–6 transverse septa and 1 longitudinal septum (Wijayawardene et al. 2014b, c). Camarosporium moricola differs from C. aureum in having smaller conidiomata (400–550 × 350–550 μm), smaller conidia ((19–)–19.5–22.5(–24) × 8–9(–10) μm) with 4–5 transverse septa, with 2–3 longitudinal septa (Liu et al. 2015). Camarosporium moricola also shows morphological similarities to its sister taxa, C. clematidis and C. spartii. Our species is distinct from C. clematidis by having conidiomata (370–425 × 350–380 μm), enteroblastic, annellidic conidiogenous cells and wider conidia 2–3 transverse and 1 longitudinal septa (Wijayawardene et al. 2014c). They differ from C. spartii by not having annelidic conidiogenous cells, larger conidia (16–13 × 6–7 μm), 3–4 transverse septa and 2–3 longitudinal septa (Wijayawardene et al. 2014b).

Eurotiomycetes O.E. Erikss. & Winka.

Eurotiomycetes was introduced by O.E. Erikss. & Winka (1997). Eurotiomycetes is a monophyletic class (Geiser et al. 2006) comprising three major clades, Chaetothyriomycetidae, Eurotiomycetidae, and Mycocaliciomycetidae. Some are human pathogens, many of the black yeasts, and some lichenized families (Kirk et al. 2008).

Eurotiales G.W. Martin ex Benny & Kimbr.

Eurotiales was introduced by G.W. Martin and validated Benny & Kimbr in 1980. The order contains three families (Elaphomycetaceae, Monascaceae and Trichocomaceae) of well known and common fungi, particularly those with phialidic Aspergillus and Penicillium asexual stages (Kirk et al. 2008).

Trichocomaceae E. Fisch.

Trichocomaceae was introduced by Fischer (1897). Species of Trichocomaceae are economically important in industry and medicine (Houbraken and Samson 2011). Phylogenetic relationships are well known for only certain genera of Trichocomaceae (Aspergillus, Penicillium and Paecilomyces) (Peterson 2000a, b; Samson et al. 2004; Peterson 2008; Samson et al. 2009), and the relationships are still poorly studied (Houbraken and Samson 2011).

Section Exilicaulis

Penicillium Link.

Species of Penicillium (Trichocomaceae, Eurotiales) are well known and abundant in soil, air, indoor environments and in contaminated foods (Frisvad and Samson 2004; Samson et al. 2010). Their main function in nature is the decomposition of organic materials and many are known for the postharvest decay of fruits and as mycotoxin producers on various foods (Frisvad and Samson 2004; Houbraken et al. 2016).

The genus Penicillium is divided into four subgenera—Aspergilloides, Penicillium, Biverticillata and Furcatum comprising 25 sections (Visagie et al. 2014). Section Exilicaulis was described by Pitt (1980), and is characterized by monoverticillate conidiophores and typified by P. restrictum. Recently, Houbraken and Samson (2011) revised the classification of the genus Penicillium based on phylogenetic data. They redefined section Exilicaulis to include species with biverticillate conidiophores, such as P. corylophilum, P. melinii, and P. raciborskii. Recently, section Exilicaulis was revised using three genes (BenA, CaM, and RPB2) to comprise eight clades defined by the inclusion of the following species: P. melinii, P. corylophilum, P. restrictum, P. citreonigrum, P. decumbens and P. parvum (Visagie et al. 2016).

As far as can be determined, only four species of Penicillium. P. daejeonium, P. koreense, P. samsonianum and P. jejuense, have been reported as new from Korea: P. daejeonium from grape and schisanda fruit, P. koreense from soil, P. samsonianum from stems and leaves of Viscum album var. coloratum, and P. jejuense from marine environments of Jeju Island.

During an investigation of the fungi associated with pomegranate fruit in Korea, a new species was isolated and is described here based on morphological characteristics and phylogenetic analyses (Fig. 72).

Material examined: REPUBLIC OF KOREA, Jeonnam Province, Gwangju (3510′N 12655′E), from a fruit of Punica granatum (pomegranate) from a grocery store and then stored in the fridge, 5 February 2016 (CNUFC-FP2-1, preserved as glycerol stock at −80 °C in the Chonnam National University Fungal Collection; isotype in Culture Collection of National Institute of Biological Resources (NIBR), Incheon); living culture (ex-type) deposited at Jena Microbial Resource Collection (University of Jena and Leibniz Institute for Natural Product Research and Infection Biology, Jena, Germany) (JMRC:SF:12421).

GenBank Numbers CNUFC-FP2-1 RPB2:KX839675; CaM:KX839671; β-tubulin:KX839673. CNUFC-FP2-2 RPB2:KX839670; CaM:KX839672; β-tubulin:KX839674.

Culture characteristics: The isolate was observed to grow over a wide range of temperatures with varying growth rates on MEA (malt extract agar), CYA (Czapek yeast autolysate agar), and YES (yeast extract sucrose agar). The average growth rates of CNUFC-FP2-1 on MEA, CYA, and YES were 5, 3, and 2.5 mm per 24 h, respectively. Optimal growth was observed around 25 °C, slow growth was observed at below 20 °C, and restricted growth at 37 °C.

Notes: Penicillium punicae is distinct from P. cravenianum and P. pagulum, growing rapidly when cultivated on MEA and CYA; whereas P. cravenianum and P. pagulum have restricted growth on MEA, and CYA, respectively. The number of phialides per metula and metulae are fewer than in P. cravenianum and P. pagulum. In the phylogenetic tree based on multiple genes, the strain formed a separate branch from other species of Penicillium sect. Exilicaulis and is considered to represent a new species.

Exophiala J.W. Carmich.

Exophiala was introduced by Carmichael (1966) to accommodate the type species E. salmonis from cerebral lesions of Salmo clarkii. It is characterized by melanin or melanin-like pigments in the cell walls, annelidic conidiogenesis and an abundance of budding cells (de Hoog and Hermanides-Nijhof 1977; Haase et al. 1999). Exophiala includes mostly black yeast asexual morphs belonging to Chaetothyriales (Untereiner et al. 1995; de Hoog et al. 2011; Zeng et al. 2014), occasionally linked to peculiar coelomycetes synanamorphs, viz. E. placitae Crous & Summerell (Crous et al. 2007). The sexual morph of Exophiala has been reported as Capronia (Herpotrichiellaceae, Chaetothyriales) (Carmichael 1967; Hironaga et al. 1981; de Hoog et al. 2011). They are present in extreme ecological niches causing animal and human diseases (Li et al. 2008, 2009; Sudhadham et al. 2008; de Hoog et al. 2011; Najafzadeh et al. 2013; Wen et al. 2015), in soil, rock surfaces, air, rhizosphere, and plant tissues (Addy et al. 2005; Julou et al. 2005; Bates et al. 2006; Neubert et al. 2006; Bukovská et al. 2010; de Hoog et al. 2011; Seyedmousavi et al. 2011; Ferrari et al. 2011; Isola et al. 2013) (Fig. 74).

Notes: We introduce a new species based on both morphology and phylogeny. Exophiala italica was found in Italy, where the sexual morph is characterized by semi-immersed to erumpent oval ascomata, ostiole, cylindric asci, club-shaped pedicel and 2-celled hyaline ascospores, constricted at the second septum. The species was mainly identified based on phylogenetic analyses with high statistical support (96% in ML/1.00 in BYPP) and clustered with E. hongkongensis. We compared the asexual morph of E. italica and found that E. hongkongensis is different (see Woo et al. 2013). E. italica is the first sexual morph report in Exophiala based on morphological characteristics and molecular data (Fig. 74).

Mucoromycotina Benny

Mucorales Fr.

Mucorales has the largest number of species within the Mucoromycota and is characterized by the formation of coenocytic hyphae with septa either at the base of the reproductive structures or irregularly distributed in old colonies (Santiago et al. 2013). Species of this order are mostly saprotrophic, and are commonly isolated from soil, stored grains, plants, and animal excrement, especially that of herbivores and rodents (Santiago et al. 2013; de Souza et al. 2016). The genus Gongronella, proposed by Ribaldi (1952), belongs to the phylum Mucoromycota, subphylum Mucoromycotina, order Mucorales and family Cunninghamellaceae (Benny et al. 2016; Spatafora et al. 2016). It includes species characterized by relatively slow growing colonies that form poorly developed stolons and rhizoids, as well as erect or circinately branched sporangiophores. The sporangia are small with a deliquescing or breaking wall, and the columellae are reduced in size, with the presence of an apophysis meaning the sporangium never has a pyriform shape. The sporangiospores are 1-celled, hyaline, smooth and variously shaped, while the brown to black zygospores are borne aerially, and have parallel suspensors devoid of appendages (Hesseltine and Ellis 1964).

Cunninghamellaceae Naumov ex R.K. Benj.

Gongronella Ribaldi

Gongronella was established to accommodate a single species: G. urceolifera Ribaldi (currently G. butleri Lendn.), previously allocated within Mortierellaceae. The presence of a distinct globose apophysis and the reduced size of the columellae were the main characteristics in the introduction of the genus (Upadhyay 1969). Peyronel and Dal Vesco (1955) and Pici (1955) transferred Absidia butleri Lendn. to Gongronella, based on the presence of a characteristic apophysis similar to those observed in the type species. Later, Hesseltine and Ellis (1961) proposed the addition of another species, G. lacrispora Hesselt. & J.J. Ellis, and recently, three new species have been described (Adamčík et al. 2015; Ariyawansa et al. 2015c; Li et al. 2016). Currently, the genus includes five species: G. butleri, G. guangdongensis F. Liu, T.T. Liu & L. Cai, G. koreana Hyang B. Lee & T.T.T. Nguyen, G. lacrispora and G. orasabula Hyang B. Lee, K. Voigt, P.M. Kirk & T.T.T. Nguyen. Species of Gongronella have traditionally been distinguished based on their morphology and sporangial stages. In recent years, however, molecular analysis has been used as an additional tool to delimitate species, causing an increase in the number of new taxa (Adamčík et al. 2015; Ariyawansa et al. 2015c; Li et al. 2016).

Gongronella brasiliensis C.A. de Souza, D.X. Lima & A.L. Santiago, sp. nov.

Index Fungorum number: IF552552; Facesoffungi number: FoF 2699, Fig. 78 Etymology: Brasiliensis, referring to country where the species was first isolated.

Holotype: URM 7487

Colonies white, cottony, low and exhibiting slow growth (6 cm diam. and 1–2 mm in height) after 7 days on MEA at 25 °C. Reverse cream to buff with irregular margins. Rhizoids frequent, slightly branched, long or short, up to 45 μm length, hyaline. Stolons present, 2–6 μm diam., hyaline, generally coenocytic, although some septa can be observed in old colonies. Odourless. Sporangiophores erect, straight or slightly recumbent, smooth-walled, hyaline, 26.5–320 × 2.5–5 μm; solitary, arising from stolons, or in whorls of two, often with a single branch, predominantly terminating in a sporangium, while those emerging directly from aerial mycelia branch repeatedly. Some branches end in a sterile sporangial, globose, 5–17 μm diam. One or two septa may form below the apophysis. Sporangia first yellowish then becoming light brownish, globose, subglobose, 9.5–30 μm diam., smooth-walled, some leaving collars. Columellae hyaline to light grey, smooth-walled, globose, subglobose, (3–)4–8(–9) μm or conical-cylindrical, 1.5–2.5 × 2–3 μm, some so small that they are almost inconspicuous, up to 1 μm diam., some with an evident collar. Apophysis hyaline, smooth-walled, variable in shape, globose, (3–)4–5(–6) μm diam., vase-shaped, (3–)4 × 12(–14.5) μm and ellipsoidal, 5–10(–12) × 3–7(–8.5) μm. Sporangiospores variable in shape, hyaline, smooth-walled, some containing oil droplets, reniform, 1.5–4 × 1.5–2.5 μm, ellipsoid to fusiform, 2–6.5 × 1.5–3 μm, ellipsoid with a flattened end, some almost falciform, 2.5–7.5 × 1.5–4. Chlamydospores present in the aerial mycelium, globose, subglobose and doliiform. Giant cells globose, subglobose, ovoid, some hypha-like and irregularly swollen, up to 48 μm diam. Zygosporangia not observed.

Media and temperature tests: On MEA at 10 °C lack of growth and sporulation. At 15 °C—colonies with slow growth, reaching 3.6 cm in diam. after 192 h; poor sporulation. At 20 °C—low (1–2 mm in 168 h) colonies with slow growth (4.3 cm in 168 h); good sporulation. Sporangiophores with mainly single branches, rarely multi-branched; Chlamydospores present, globose to subglobose; giant cells absent. At 25 °C—low (1–2 mm in 168 h) colonies, better growth (6 cm in 168 h); excellent sporulation. At 30 °C—good growth 5.6 cm in 168 h; excellent sporulation. The growth of G. brasiliensis on PDA was slightly slower than on MEA at all tested temperatures.

Material examined: BRAZIL, Taquaritinga do Norte, state of Pernambuco (752′28″S, 3559′25″W), in soil samples. Soil, 5.XI.2015, leg. C.A.F de Souza (URM 7487, holotype). Gene bank numbers ITS:KY114930; KY114931.

Notes: According to the phylogenetic (ITS) and morphophysiological analyses, G. brasiliensis exhibits well-supported genetic datasets and morphological characteristics that differentiate it from other species of the genus (Fig. 78). Gongronella brasiliensis produces elliptical apophysis, conical-cylindrical columellae and giant cells not so far reported for this genus. G. brasiliensis may have been previously confused with G. butleri because of the branching pattern of the sporangiophores and for the size and shape of the sporangia. However, only the former produces elliptical apophysis, conical-cylindrical columellae and giant cells (Fig. 77). Additionally, colonies of G. brasiliensis are persistently white, in contrast to the colonies of G. butleri that are at first white, later becoming olive-buff or olive-gray (Upadhyay 1969). In most species of Gongronella, one septum is commonly observed below the sporangia. The presence of two septa delimiting the sporangia was only observed in G. orasabula and G. brasiliensis. Additionally, the sporangiospores of G. brasiliensis are variable in shape and larger than those observed in G. butleri, G. guangdongensis, G. koreana and G. orasabula (Figs. 79, 80).

Rhizopodaceae K. Schum.

Mucor Fresen.

The genus Mucor includes primarily saprotrophic species characterized by the production of fast-growing colonies, simple or branched sporangiophores without basal rhizoids, non-apophysate sporangia, and seldomly produced zygospores which are borne from opposed suspensors, possess a thick pigmented and ornamented zygosporangium (Schipper and Samson 1978). The species within the genus can be easily isolated from soil, dung, water, stored grains and other plant parts (Benny 2008; Li et al. 2016). Mucor spp. are commonly reported in different herbivore faeces (Thilagam et al. 2015; Li et al. 2016; Nguyen et al. 2016). On these substrates, Zygomycetes usually appear first, followed by ascomycete and finally basidiomycete fungi. Among the Zygomycetes found in dung, species of Mucor were dominant (Benny 2008). In Korea, a small number of Mucorales have reported from animal fecal (Li et al. 2016; Nguyen et al. 2016).

Traditional taxonomy of species of Mucor was based on morphological characteristics such as the size and shape of sporangia, as well as the mode of reproduction (sexual or asexual). Recently, molecular data have been used to evaluate mucoralean species (Hoffmann et al. 2013; Walther et al. 2013; Ariyawansa et al. 2015c).

During a study on the Mucorales from animal faecal samples in Korea, a species of Mucor that differed morphologically and phylogenetically from other species was isolated and is thus described as new.

MycoBank number: MB 818383; Facesoffungi number: FoF 2799, Fig. 81

Etymology: stercorarius. Named for rat dung from which the species was first collected.

Holotype: CNUFC-UK2-1

Colonies growing fast on SMA, white, grayish-white in reverse, reaching 42–45 mm diam. at 20 °C after 2 days of incubation. Sporangiophores 4.5–7 μm wide, erect, branched sympodially. Sporangia globose to subglobose, yellow, multi-spored, reaching 30–38.5 × 27.5–37 μm; sporangial wall at maturity fully deliquescent, leaving a small collar on the sporangiophore. Columellae of diverse shape, globose to subglobose or pyriform, 15.5–22 × 17–25 μm. Sporangiospores ellipsoidal, 6.5–10 × 3.5–6 μm. Zygospores 38–83 × 45–86 μm.

Material examined: REPUBLIC OF KOREA, Jeonnam Province, garden of the Chonnam National University located in Gwangju (3510′N 12655′E), from a rat fecal sample, 24 February 2016 (CNUFC-UK2-1 preserved as glycerol stock at −80 °C in the Chonnam National University Fungal Collection (CNUFC); isotype in Culture Collection of National Institute of Biological Resources (NIBR), Incheon; living culture (ex-type) deposited at Jena Microbial Resource Collection (University of Jena and Leibniz Institute for Natural Product Research and Infection Biology, Jena, Germany) (JMRC:SF:12422).

GenBank Numbers CNUFC-UK2-1 LSU:KX839685; SSU:KX839684; ITS:KX839689; TEF1:KX839681; Actin:KX839688. CNUFC-UK2-2 LSU:KX839682; SSU:KX839686; ITS:KX839680; TEF1:KX839687; Actin: KX839683.

Culture characteristics: The isolate grew over a wide range of temperatures with varying growth rates on SMA, PDA (potato dextrose agar), and MEA (malt extract agar) of 21.5, 17.5 and 23 mm per 24 h, respectively. Optimal growth was 20–25 °C, slow growth at 5 °C, and no growth at 37 °C.

Notes: Mucor stercorarius is similar in morphology and closely related to M. genevensis but differs by forming smaller sporangia. Columellae are diverse in shape and smaller than those of M. genevensis; sometimes a, bell-shaped apophysis was present. Moreover, the new species grows and sporulates at 35 °C, whilst M. genevensis does not. In the phylogenetic tree of ITS and multiple genes, the strain forms a branch separate from other species of Mucor, supporting its establishment as a new species.

Sordariomycetes O.E. Erikss. & Winka

Sordariomycetes is the second largest class of Ascomycota (Hyde et al. 2013) including 6 subclasses, 32 orders, 105 families and 1331 genera (Maharachchikumbura et al. 2016). The Sordariomycetes have a cosmopolitan distribution comprising terrestrial and aquatic taxa (Jones et al. 2015; Pratibha et al. 2014). Species are characterized by perithecial ascomata and inoperculate unitunicate asci (Zhang et al. 2006) or non-fissitunicate asci (Kirk et al. 2008). The class includes many important plant pathogens, endophytes, saprobes, epiphytes, coprophilous, fungicolous, and lichenized or lichenicolous taxa (Maharachchikumbura et al. 2016) (Figs. 79, 80).

Diaporthales Nannf.

The Diaporthales was introduced by Nannfeldt (1932), and includes a number of plant pathogenic fungi and many asexually reproducing fungi (Castlebury et al. 2002; Rossman et al. 2007).

Gnomoniaceae G. Winter

Gnomoniaceae was introduced by G. Winter (1886) with Gnomonia Ces. & De Not. 1863 as the type genus. Species in Gnomoniaceae can exist as saprobes as well as cause serious tree diseases (Rossman et al. 2007). They are characterized by ascomata that are generally immersed, solitary, without a stroma, or aggregated with a rudimentary stroma (Sogonov et al. (2008).The genera of Gnomoniaceae were listed by Sogonov et al. (2008) (Fig. 82).

Gnomoniopsis Stoneman

Gnomoniopsis Berl. was introduced based on the type species G. chamaemori (Fr.) Berl. (Barr 1978; Monod 1983; Walker et al. 2010). Gnomoniopsis is characterized by having small, black perithecia, solitary or in groups in a minimal stroma, and 1-septate, oval to fusiform ascospores. Sogonov et al. (2008) identified some Sirococcus species as the asexual morph of Gnomoniopsis. Most species of Gnomoniopsis occur on plants of the Fagaceae, Onagraceae and Rosaceae. Gnomoniopsis also contains economically important pathogens of rosaceous crop plants, including blackberry, raspberry, and strawberry (Bolay 1971; Monod 1983; Maas 1998). An updated phylogeny of Gnomoniopsis with new isolates based on a combined gene analysis is presented (Fig. 83).

GenBank Numbers LSU:KY496735; ITS:KY496755; SSU:KY501123; TEF1:KY514399.

Notes: Walker et al. (2010) chose a lectotype of G. sanguisorbae but their illustration is not clear. However, our phylogenetic tree shows that our strain groups with other strains of G. sanguisorbae. We also compared the morphology of our strain with G. sanguisorbae and found that it matches. We therefore designate G. sanguisorbae (MFLU 15-1255) as a reference specimen (sensu Ariyawansa et al. 2014b).

Sydowiellaceae Lar.N. Vassiljeva

Sydowiellaceae was established in Diaporthales by Lar.N. Vassiljeva (1987) based on S. fenestrans (Duby) Petr. (Rossman et al. 2007, Senanayake et al. 2017). The family accommodates 15 genera with 43 species, but several taxa do not share any clear morphological features in common (Rossman et al. 2007; Liu et al. 2015; Maharachchikumbura et al. 2015, 2016; Senanayake et al. 2017). Members of Sydowiellaceae are found on herbaceous, dicotyledonous plants and hardwood trees as pathogens and saprobes (Rossman et al. 2007).

Sillia P. Karst.

Sillia was introduced by P. Karsten (1873), with the type S. ferruginea (Pers.) P. Karst. There are six species listed in Index Fungorum (2017) and Senanayake et al. (2017) added a new species, S. karstenii. Sillia is characterized by stromata with numerous ascomata with long cylindrical necks and stromatic tissues, which turn to red in 10% KOH (Iznova and Rukseniene 2012). A revised phylogeny among members of the Diaporthales is presented in Fig. 84

Holotype: MFLU 16-0056

Saprobic on dead branch of Corylus sp. (Corylaceae). Sexual morph Stroma erumpent from cracks, up to 1–2.5 mm in diam., black on the surface. Ascomata 480–745 µm high × 136–346 µm diam. (\( \bar{x} \) = 640 × 242 µm, n = 10), semi-immersed in black stromatic tissues gregarious, globose to subglobose, ostiolate, soft and found in a valsoid arrangement. In 10% KOH solution stroma becomes brownish-red. Ostioles 330–570 μm long, cylindrical, forming at the center of the ascomata, raised from the host surface. Peridium 20–34 μm thick, with outer layer of brown and thick-walled cells of textura prismatica; inner layer of hyaline and thin-walled cells of textura angularis. Paraphyses 4–7 µm wide, cylindrical, cellular, septate, mixed with asci. Asci 147–234 × 10–15 μm (\( \bar{x} \) = 190 × 13 µm, n = 25), 8-spored, unitunicate, narrowly clavate, straight or somewhat curved, with a short obtuse pedicel.

Asexual morph Undetermined.

Material examined: ITALY, Forlì-Cesena Province, Monte Mirabello–Predappio, on dead twig of Corylus sp. (Corylaceae), 11 January 2016, Erio Camporesi, IT2754 (MFLU 16-0056 holotype, BBH isotype).

GenBank Numbers LSU:KY397949; ITS:KY523484.

Notes: Sillia italica strains analyzed herein are sister taxa to S. ferruginea, S. karstenii and this relationship is well-supported (Fig. 84). This close phylogenetic affinity is also supported by morphological similarities. Both S. ferruginea and S. italica become reddish in 10% KOH solution (Iznova and Rukseniene 2012). Sillia italica however, has some distinct characters as compared to S. ferruginea. Stromatic tissues of S. ferruginea comprise black tissues on the surface and inner yellow stromatic tissues mixed with black tissues (Iznova and Rukseniene 2012), while S. italica contains black stromatic tissues. The ascomata arrangement of S. italica is valsoid, whereas in S. ferruginea it is diatrypoid. Sillia italica has clavate asci similar to S. ferruginea, but they are longer (147–234 µm vs. 96–115 µm). Ascospores of S. italica are 99–128 µm long with 3 septa, while in S. ferruginea they are 65–72 µm long with 3–5 septa. Senanayake et al. (2017) introduced Sillia karstenii which morphologically differs from S. italica in having large ascomata with very poorly developed stromata. The phylogenetic analysis of Senanayake et al. (2017) also showed that S. italica is phylogenetically distinct from other Sillia species (Fig. 86).

Cytospora was introduced by Ehrenberg (1818) and is an important pathogenic genus causing canker disease on branches leading to dieback on a wide range of plants. (Adams et al. 2005, 2006; Hyde et al. 2016; Norphanphoun et al. 2017). See Norphanphoun et al. (2017) for a recent account of the genus. An updated tree for the genus is provided in Fig. 87.

Material examined: RUSSIA, Rostov Region, Krasnosulinsky District, Donskoye forestry, lining-out nursery, trees and shrubs, dying twigs and branches of Cotinus coggygria (Anacardiaceae), 27 October 2015, T. Bulgakov; T-1117 (MFLU 15-3779, holotype), ex-type living culture, MFLUCC 16-0634, KUMCC.

Notes: In the phylogenetic analyses (Fig. 87), C. gelida groups with C. cotini (strain MFLUCC 14-1050) and C. ribis (strain 284-2). Cytospora gelida can be distinguished from C. cotini by its multi-loculate (>4) conidiostromata, while C. cotini has 2–3 locules in the conidiostromata. The conidia of C. gelida are larger than C. cotini (6.9 × 1.8 vs. 5.9 × 1.2 µm). Cytospora gelida differs from C. cotini in the polymorphic nucleotides of ITS, RPB2 and Actin sequence data. In ITS it differs with two polymorphisms, and RPB2 in 17 polymorphisms.

Material examined: RUSSIA, Rostov Region, Krasnosulinsky District, Donskoye forestry, Kabanya Balka (Boar gully), artificial forest, dying twigs and branches (necrotrophic) on Acer platanoides (Sapindaceae), 27 October 2015, T. Bulgakov; T-1095 (MFLU 15-3757, new record); living culture, MFLUCC 16-0625, KUMCC.

Notes: Cytospora ceratosperma has been reported on hosts worldwide (Ahmad 1969; Pantidou 1973; Simonyan 1981; Truszkowska and Chlebicki 1983; Cannon et al. 1985; Spielman 1985; Ahmad et al. 1997; Dudka et al. 2004; Mulenko et al. 2008; Fotouhifar et al. 2010; Rossman et al. 2015). The characters of the sexual morph in our collection indicate it belongs to Cytospora in having a large circular area, with 3–6-ostioles per group, with asci (\( \bar{x} \) = 63 × 11 μm) and ascospores (\( \bar{x} \) = 14.5 × 3.7 μm). In the phylogenetic analyses of our collection (strain MFLUCC 16-0625), groups with C. rosarum (strain 218), collected from Rosa canina (Fotouhifar et al. 2010) (Fig. 86). The current study represents the first record of maple canker caused by C. ceratosperma in Russia.

Cytospora ceratosperma has not been epitypified and therefore we treat MFLUCC 16-0625 as a reference specimen (Ariyawansa et al. 2014b). Fresh collections of C. ceratosperma from the type location and host are needed for epitypification.

Hypocreales Lindau

Bionectriaceae, Clavicipitaceae, Cordycipitaceae, Flammocladiaceae, Hypocreaceae, Nectriaceae, Niessliaceae, Ophiocordycipitaceae, Stachybotryaceae and Tilachlidiaceae are included in the order Hypocreales (Maharachchikumbura et al. 2015). Hypocreales are highly diverse and found in the tropics and subtropics (Põldmaa 2011). They are characterized by pigment producing, brightly coloured perithecial ascomata, and typically ostiolate perithecial fruiting body (Rogerson 1970; Rehner and Samuels 1995).

Clavicipitaceae Earle

The families Clavicipitaceae, Cordycipitaceae and Ophiocordycipitaceae were recognized by Sung et al. (2007) based on phylogenetic analyses. The family Clavicipitaceae (Hypocreales) is a very heterogeneous group comprising obligate saprotrophes, parasites and symbionts with insects and, fungi or grasses, rushes or sedges (Sung et al. 2007; Schardl et al. 2013; Kepler et al. 2013; Li et al. 2016). Maharachchikumbura et al. (2015) listed 48 genera under this family.

Species of Hypocrella, Moelleriella and Aschersonia belong to the family Clavicipitaceae and are pathogens of scale insects and whiteflies and are common in tropical regions (Chaverri et al. 2008). Most species of Hypocrella produce an Aschersonia asexual morph that is characterized by pycnidia or acervuli on a stroma, often filled with brightly coloured, slimy conidia (White et al. 2003; Chaverri et al. 2005). Moelleriella was described by Bresadola (1896) and it produces filiform, multi-septate ascospores, that disarticulate at the septa within the ascus and an aschersonia-like asexual morph with fusoid conidia (Chaverri et al. 2008) (Fig. 89).

Conidiomata 1.4–2.2 × 0. 45–0.55 mm (\( \bar{x} \) = 1.784 × 0.493 mm, n = 10), reddish-brown, solitary, irregular in shape, surface roughened, flattened pulvinate, multi-loculate, locules 520–638 × 385–455 µm (\( \bar{x} \) = 579 × 420 µm, n = 20), brown, immersed, globose or subglobose to obpyriform, ostiolate. Ostioles subcylindrical, single, well-developed, centrally located. Wall of conidiomata 19–29 µm wide, composed of relatively thick-walled, brown cells of textura oblita in the outer layers and thin-walled, hyaline cells of textura angularis in the inner layers. Paraphyses 163–308 × 1.2–1.6 µm (\( \bar{x} \) = 236 × 1.4 µm, n = 150), hyaline, filiform, tapering at the apices, arising from the hymenium of the conidioma. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 8–14 × 1–1.5 µm (\( \bar{x} \) = 11 × 1.2 µm, n = 90), hyaline, phialidic, cylindrical to subcylindrical, broad at base, discrete, smooth, arising from the inner layers of conidioma. Conidia 11–13 × 2.1–2.9 µm (\( \bar{x} \) = 12 × 2.5 µm, n = 150), hyaline, fusiform, unicellular, straight or slightly curved, guttulate, thick-and smooth-walled, accumulating in a slimy yellowish mass above the conidioma.

Culture characteristics: Cultures were obtained from germinating ascospores and conidia. The ascospores and conidia germinated within 48 h on PDA. Colonies on PDA were irregular and approx. 2 cm diam. after 4 weeks at 20 °C. The colonies derived from germinating ascospores or conidia formed a compact mycelium. The colonies have rough surface, viscous texture, knobly protuberances and curled margin. The conidial mass was pale yellow to yellow appearing as abundant slimy masses scattered over the surface of stromatic colonies.

Notes: The sexual morph of this species was not found in the field although several attempts were made to find it throughout the year. Moelleriella thanathonensis is similar to three widespread species in Thailand, namely Moelleriella raciborskii (Zimm.) P. Chaverri, M. Liu & K.T. Hodge, M. libera (Syd. & P. Syd.) P. Chaverri & M. Liu and Aschersonia placenta Berk. Aschersonia placenta is the asexual morph of Moelleriella raciborskii (syn. Hypocrella raciborskii Zimm.) (Liu et al. 2009). Moelleriella libera is the sexual morph of Aschersonia aleyrodis Webber (Chaverri et al. 2008). Our new species M. thanathonensis is characterized by multi-locular conidiomata, fusiform conidia and phialidic conidiogenous cells. In this paper, we provide a synopsis of morphologically similar asexual morph species to M. thanathonensis in Table 3. Phylogenetic analysis of combined TEF1, RPB1 and RPB2 sequence data (Fig. 89) also provides evidence that M. thanathonensis is a new species.

Stachybotryaceae L. Lombard & Crous

Stachybotryaceae was introduced with its type genus Stachybotrys (Corda 1837) and is typified by S. chartarum (Ehrenb.) S. Hughes (Wang et al. 2015). Presently, 33 genera are accepted in the family Stachybotryaceae (Lombard et al. 2016; Lin et al. 2016) (Fig. 92).

Myrothecium Tode

Myrothecium was introduced by Tode (1790) with M. inundatum Tode as the type species. Species of this genus are saprobes in the soil and plant pathogens (Ellis and Ellis 1985; Watanabe 1994; Chen et al. 2016). More than 30 species of this genus have been recorded worldwide (Seifertk et al. 2011; Chen et al. 2016; Lombard et al. 2016).

Notes: Myrothecium septentrionale is similar to M. chiangmaiense D.Q. Dai & K.D. Hyde in morphology. However, M. septentrionale and M. chiangmaiense are phylogenetically distinct and the latter is basal to M cinctum and M. gramineum, while M. septentrionale is closely related to M. roridum with high support (Fig. 92). Myrothecium septentrionale differs from M. roridum in having larger ampulliform conidia (8.6–12 × 1.2–2.1 µm vs. 5–6 × 1–1.2 µm), while M. roridum has cylindrical conidia.

Glomerellaceae Locq. ex Seifert & W. Gams

Glomerellaceae is a monotypic family which mainly comprises plant pathogens. The family was invalidly published by Locquin (1984) and was validated in Zhang et al. (2006). This family was accepted as one of the four families of Glomerellales in Maharachchikumbura et al. (2015). This family is characterized by the Colletotrichum asexual morph and the Glomerella sexual morphs, which are now named as Colletotrichum (Hyde et al. 2014; Maharachchikumbura et al. 2015).

Colletotrichum Corda.

This genus was introduced by Corda (1831), for C. lineola Corda (Damm et al. 2009). Colletotrichum species are mainly plant pathogens, but also endophytes and saprobes (Yang et al. 2009; Hyde et al. 2009; Cannon et al. 2012; Jayawardena et al. 2016a, b). Kirk et al. (2001, 2008), Réblová et al. (2011) referred Colletotrichum to the family Glomerellaceae and Maharachchikumbura et al. (2016) further confirmed the familial affinities of this genus (Fig. 94).

Colletotrichum sambucicola Jayawardena, Camporesi & K.D. Hyde, sp. nov.

Index Fungorum number: IF552553; Facesoffungi number: FoF 2683, Fig. 95

Holotype: MFLU 16-2675

Saprobic on dead branch of Sambucus ebulus L. Sexual morph Undetermined. Asexual morph Conidiomata 0.13–0.4 mm (\( \bar{x} \) = 0.27 mm, n = 10) diam., black, acervulus, oval, solitary, gregarious. Setae straight or ± bent, abundant, dark brown, becoming paler towards the apex, opaque, smooth walled, septate, 1–6-septate, 110–145 μm long, base cylindrical, slightly inflated, 6.1–8.5 μm diam., apex acute to rounded, smooth. Conidiophores simple, to 20 μm long, hyaline to pale brown, smooth-walled. Conidiogenous cells 9–16 × 2–4 μm (\( \bar{x} \) = 11.9 × 2.9 μm, n = 20), phialidic, hyaline, smooth-walled, cyllindrical to slighty inflated, opening 1–2 μm wide, collarette or periclinal thickening observed. Conidia 12.2–29.7 × 3–5 μm (\( \bar{x} \) = 17.7 × 3.8 μm, n = 15), L/W ratio 4.7, hyaline, smooth or verruculose, aseptate, curved, both sides gradually tapering towards the round to slightly acute apex and truncate base, guttulate. Appressoria not observed.

Reverse olivaceous green, concentric rings can be clearly observed, reaching 40–55 mm in 7 days at 25 °C.

Material examined: ITALY, Province of Forlì-Cesena [FC], Meldola, on dead branch of Sambucus ebulus (Adoxaceae), 30 March 2016, Erio Camporesi IT 2902 (MFLU 16-2675, holotype); ex-type living culture, MFLUCC 16-1388, KUMCC 16-0127.

GenBank Numbers ITS:KY098781, KY595193; GAPDH: KY098780, KY595192; CHS:KY098779, KY595190; Actin: KY098778, KY595190; TUB2: KY098782, KY595194 respectively.

Notes: Colletotrichum dematium species complex is mainly characterized by species with curved conidia (Damm et al. 2009; Jayawardena et al. 2016a, b). Colletotrichum sambucicola falls within the C. dematium species complex clade and forms a separate branch with 100% bootstrap support and 1.00 Bayesian posterior probability and is a sister taxon to C. anthrisci (Fig. 95). Among the species with angular conidia, conidia of C. anthrisci have the highest L/W ratio (7.8) and the apex is strongly pointed. Colletotrichum sambucicola differs from C. anthrisci in having conidiogenous cells with a distinct collarette, as well as by having smaller conidia. A BLASTn search of NCBI GenBank with the ITS sequence of MFLUCC 16-1388 showed 99% similarity to quite a number of Colletotrichum species with angular conidia. The closet match in a BLASTn search in GenBank with the GAPDH sequence of MFLUCC 16-1388 was GenBank GU228237 (98% identity, three bp differences) and CHS GU228335 (98% identity 4–7 bp differences). The newly described taxon differs from its sister taxon C. anthrisci in six bp in ITS, eight bp in GAPDH, four bp in CHS, 39 bp in Actin and four bp in TUB2 (Fig. 96).

Xylariales Nannf.

Xylariales was introduced by Nannf. 1932 and this order is the largest order of perithecial ascomycetes. Familial relationships in this order have been investigated (e.g. Tang et al. 2009) and currently 22 families are accepted Maharachchikumbura et al. (2016).

Bartaliniaceae Wijayaw. et al.

Based on morphology and DNA sequence data, Senanayake et al. (2015) introduced the family Bartaliniaceae to accomodate the genera Bartalinia, Broomella, Dyrithiopsis, Hyalotiella, Truncatella and Zetiasplozna. Later Wijayawardene et al. (2016) included the genera Doliomyces Steyaert and Morinia Berl. & Bres. Doliomyces is known to be morphologically similar to the other genera of the family but there is no sequence data yet to confirm this placement (Wijayawardene et al. 2016). Morinia Berl. & Bres. has uniquely distinct morphological features but phylogenetically groups within Bartaliniaceae (Wijayawardene et al. 2016). Bartaliniaceae is phylogenetically related to the families Sporocadaceae, Pestalotiopsidaceae and Robillardaceae (Jeewon et al. 2002, 2003a; Senanayake et al. 2015; Maharachchikumbura et al. 2016).

Truncatella Steyaert

The genus Truncatella, typified by T. truncata was established by Steyaert (1949) to accommodate distinct species having 3-septate, verruculose, pigmented conidia (Steyaert 1949; Jeewon et al. 2002; Maharachchikumbura et al. 2012, 2015). The genus was previously placed in Amphisphaeriaceae, Xylariales (Jeewon et al. 2003a; Lumbsch and Huhndorf 2010), and later included in Bartaliniaceae by Senanayake et al. (2015) based on both morphological features and molecular evidence. Several studies have contributed to the phylogenetic understanding of Truncatella, such as its affinity to Bartalinia (Jeewon et al. 2002; Lee et al. 2006; Maharachchikumbura et al. 2012, 2014a, b, 2016, 2017; Senanayake et al. 2015; Maharachchikumbura et al. 2017) and Neotruncatella (Hyde et al. 2016). The sexual morph of Truncatella remains largely unresolved, however Senanayake et al. (2015) illustrated both the sexual and asexual morph for T. spartii.

Conidiomata wall consisting of outer light brown to hyaline cells of textura angularis and inner hyaline cells of textura angularis to textura globulosa. Conidiophores 2.5–4 μm long, hyaline, cylindrical, simple or branched. Conidiogenous cells 8.5–14.2 μm long hyaline, simple, filiform, annelidic, indeterminate, integrated. Conidia 17.5–24.8 × 5.3–7.2 μm (\( \bar{x} \) = 21.5 × 6.5 μm, n = 30), broadly fusiform, 3-septate, slightly constricted at the mid septum, verruculose, median cells brown to yellowish-brown, 10.5–15 μm long, thick-walled, globules present, basal cell hyaline, conical tapering towards the base with an acute apex, apical cell hyaline, bearing 3 appendages.

Material examined: ITALY, Province of Forlì-Cesena [FC], near Camposonaldo—Santa Sofia, on dead cone attached to Picea excelsa (Pinaceae), 6 May 2013, Camporesi Erio, IT1226 (HKAS96302, new host record), living culture KUMCC 15-0127.

GenBank Numbers ITS:KY 474383.

Notes: This is the first record of Truncatella sparti on Picea excelsa. This species was introduced by Senanayake et al. (2015) from the host Spartium with both sexual and asexual morphs illustrated. Truncatella spartii is closely related to T. hartigii (Tubeuf) Steyaert, T. helichrysi (Severini) B. Sutton and T. restionacearum S. Lee & Crous, but differs in the apical cell characteristics of its conidia (Lee et al. 2006; Senanayake et al. 2015).

Myrmecridiales Crous

Myrmecridium Arzanlou, W. Gams & Crous.

The genus Myrmecridium was described by Arzanlou et al. (2007) with the type species M. schulzeri. To date, 10 species of Myrmecridium have been described (Peintner et al. 2016). Species belonging to this genus are characterized by the production of obovoid or fusiform conidia, tapering towards a narrowly truncate base, hyaline mycelium with pale to unpigmented, and pimple-like denticles. They are frequently isolated from soils and plant tissues (Crous et al. 2011; Jiea et al. 2013; Peintner et al. 2016). Some species possess potent antimicrobial activity (Zhang et al. 2012a). Molecular data have been used to evaluate species of Myrmecridium (Crous et al. 2015a; Réblová et al. 2016; Peintner et al. 2016). In a previous study a new species, Myrmecridium fluviae, was reported from a freshwater sample from Yeongsan River in Gwangju, Korea (Hyde et al. 2016).

While examining the diversity of fungi from freshwater sample of Yeongsan River in Gwangju, Korea, a new species was isolated and is described here based on morphological characteristics and phylogenetic analyses (Fig. 98).

Myrmecridium fluviae Hyang B. Lee & T.T.T. Nguyen, sp. nov.

MycoBank number: MB 818334; Facesoffungi number: FoF 2806, Fig. 99

Etymology: fluviae. Referring to fresh water from which the species was first isolated.

Holotype: CNUFC-YR61-1

Sexual morph Undetermined. Asexual morph Colonies on OA growing very slowly, grey olivaceous, reaching 15–17 mm diam. at 25 °C after 7 days incubation; reverse olivaceous black with a white margin. Conidiophores arising vertically from aerial hyphae, straight to irregular, branched, septate, varying greatly in length, 3–4.5 μm diam. Conidiogenous cells cylindrical, holoblastic, polyblastic, forming a rachis with scattered pimple-shaped denticles. Conidia produced laterally or apically, obovoid to fusoid, wall smooth to slightly rough, 7.5–12 × 3–4 μm. On PDA growth is faster than on OA and MEA, greenish-olivaceous, reverse olivaceous-buff; on MEA, surface greyish-sepia.

Material examined: REPUBLIC OF KOREA, Jeonnam Province, Yeongsan River located in Gwangju (3510′N 12655′E), from a freshwater sample, 15 February 2016 (CNUFC-YR61-1, preserved as glycerol stock at −80 °C in the Chonnam National University Fungal Collection; isotype in Culture Collection of Nakdonggang National Institute of Biological Resources (NNIBR), Sangju, Gyeongbuk Province); living culture (ex-type) deposited at Jena Microbial Resource Collection (University of Jena and Leibniz Institute for Natural Product Research and Infection Biology, Jena, Germany) (JMRC:SF:12423).

GenBank Numbers CNUFC-YR61-1 LSU:KX839677; ITS:KX839678. CNUFC-YR61-2 LSU:KX839676; ITS:KX839679.

Culture characteristics: The isolate grew over a wide range of temperatures with varying growth rates on PDA, MEA and OA with average growth rates of 2.8, 2.5, and 2.2 mm per 24 h, respectively, for CNUFC-YR61-1. Optimal growth around 25 °C to 27 °C, slow growth at 10 °C, and no growth at 35 °C.

Notes: Myrmecridium fluviae is morphologically distinct from other species, especially from M. phragmitis and M. flexuosum by having larger conidia with smooth to slightly rough-walls, sometimes forming a spiny layer. Our phylogenies provide sufficient evidence to justify the new species, albeit not strong, possibly due to inadequate taxon sampling and sequence data from other genes.

Xylariaceae Tul. & C. Tul.

The family Xylariaceae was introduced by Tulasne and Tulasne (1963) using the term “Xylariei” and the rank of the name was not certain as it did not address the family concept (Stadler et al. 2013). Even though the exact number of currently accepted taxa varies, the recent outline of Xylariaceae (Maharachchikumbura et al. 2015) accepted 87 genera. The segregation of Xylariaceae into the subfamilies Hypoxyloideae and Xylarioideae have been supported by molecular data (Tang et al. 2009; Stadler et al. 2013; Daranagama et al. 2015; Maharachchikumbura et al. 2015). The xylariaceae are mainly saprobes, while several species can also be found as pathogens and endophytes.

Rosellinia De Not.

Rosellinia was introduced by De Notaris (1844) with R. aquila (Fr.) Ces. & De Not. as the type species. According to the world monograph by Petrini (2013) only 142 species are accepted, of which 37 species are described as new species (Fig. 100).

Rosellinia mearnsii Tennakoon, Phookamsak & K.D. Hyde, sp. nov.

Index Fungorum number: IF552779; Facesoffungi number: FoF 2718, Fig. 101

Etymology: Name reflects the host Acacia mearnsii, from which the holotype was collected.

Holotype: MFLU 16-1382

Saprobic on dead stem of Acacia mearnsii De Wild. Sexual morph Stromata globose, with a conical pointed top, 700–750 µm high × 550–580 µm diam. (\( \bar{x} \) = 735 × 565 μm, n = 10), black, shiny, solitary, aggregated into small groups, carbonaceous, flattened base, surrounded by grey to pale brown, woolly to felty subiculum, confined to the stromatal base, ostiolate. Ostioles black, distinctively papillate. Ascomata, globose, uni-loculate, 550–625 µm high × 390–485 µm diam. (\( \bar{x} \) = 576 × 445 μm, n = 20). Peridium black, thick-walled, with several compressed cell layers, carbonaceous. Ascomata 600–650 × 550–580 µm (\( \bar{x} \) = 635 × 565 μm, n = 10), nearly semiglobose, surface convex, dark, smooth, with a central black papilla and ostiole. Peridium black, thick walled, compressed and carbonaceous. Paraphyses at base (3.6–)3.8–4.6(–4.9) μm wide (\( \bar{x} \) = 4.2 μm), distinct septate, slightly longer than asci, filamentous, unconstructed and hyaline. Asci (198.2–)202–224(–232.5) × (9.6–)11.5–14.2(–15.5) μm (\( \bar{x} \) = 215 × 12.5μm, n = 20) 8-spored, bearing part cylindrical, short pedicellate, with barrel-shaped, subapical, J + ring, 15.6–15.9 µm high, 7.9–8.4 µm diam., apically rounded with well-developed ocular chamber. Ascospores (44.7–)46.2–53.4(–56.3) × (7.9–)8.2–8.8(–9.1) μm (\( \bar{x} \) = 49.3 × 8.6 μm, n = 20), overlapping, inequilaterally fusiform, uni-seriate, initially hyaline to slight brown, becoming brown colour, aseptate, straight to curved, smooth walled with prominent guttules. Asexual morph Undetermined.

Material examined: CHINA, Yunnan Province, Xishuangbanna, Nabanhe, dead branch of Acacia mearnsii (Mimosaceae), 20 November 2015, D.S. Tennakoon, DXH 21 (MFLU 16-1382, holotype; HKAS 93712, isotype).

GenBank Numbers LSU:KY514060; ITS:KY514059; RPB2:KY514061.

Notes: Rosellinia mearnsii resembles R. lamprostoma in having asymmetrically ellipsoidal to slightly fusoid, light brown ascospores (Petrini 2013). However, R. mearnsii differs from R. lamprostoma in its globose ascomata and prominent guttules in the ascospores, whereas stromata in R. lamprostoma are conical, pear shaped and ascospores with inconspicuous guttules (Petrini 2013). The size ranges of ascomata also differ (550–625 μm high × 390–485 μm diam., in R. mearnsii and 700–1050 μm high × 625–1250 μm diam., in R. lamprostoma). Rosellinia mearnsii is also reminiscent to R. capetribulensis, which has fusiform, brown ascospores and a barrel-shaped apical ring (Bahl et al. 2005). However, in R. capetribulensis, the asci are clavate as compared to the cylindrical asci in R. mearnsii. Although the ascospores in R. mearnsii and R. capetribulensis different in length, the spores of R. capetribulensis are 103–155 × 15–22.5 μm, whereas those in R. mearnsii are 46.2–53.4 × 8.2–8.8 μm. Furthermore, Rosellinia mearnsii resembles R. chiangmaiensis in having ellipsoidal to slightly fusoid, brown ascospores, but R. chiangmaiensis can easily be distinguished from R. mearnsii in having an inverted hat-shaped apical ring and ascospores with a thin mucilaginous sheath (Li et al. 2016).

Phylogenetic analyses of combined ITS, LSU and RPB2 sequence data show that R. mearnsii clusters with R. lamprostoma with strong support (100% ML, 100% MP, 1.00 BYPP, Fig. 101). Besides the morphological differences, R. mearnsii differs from R. lamprostoma in having six ITS base pair and seven RPB2 base pair differences.

Evlachovaea B.A. Borisov & Tarasov

The genus Evlachovaea was established by Borisov and Tarasov (1999) and since then this genus is a monotypic with E. kintrischica Borisov and Tarasov as the type species. Only one species (Evlachovaea kintrischica B.A. Borisov & Tarasov 1999) has so far been reported from this genus (Index Fungorum 2017) (Figs. 102, 103).

Etymology: specific epithet ‘indica’ refers to the country of origin.

Holotype: AMH 9760

On live Mantispa sp. in terrestrial habitats. Asexual morph Conidiophores mononematous, unbranched to branched, sometimes apical region extends to form long whip like structure producing solitary and short conidiogenous cells unilaterally or verticillately, smooth-walled, hyaline, 25–80 × 1.5–2.5 µm (\( \bar{x} \) = 47 × 3.29 µm, n = 30). Conidiogenous cells phialides in whorls of 2–8, or more, occasionally solitary on conidiophores or arising from a vegetative hypha, with slightly inflated and narrowed towards base, smooth-walled, hyaline, tapering with long slender neck, 8–40 × 1–2.39 µm (\( \bar{x} \) = 16.24 × 1.49 µm, n = 30). Conidia produced in long basipetal chains, forming a zip-like pattern, oval or subglobose, broadly ellipsoidal to clavate, smooth-walled, hyaline, 1.75–9 × 1–3 µm (\( \bar{x} \) = 6.40 × 2.07 µm, n = 30). Sexual morph Undetermined.

Culture characteristics: on semi-synthetic agar medium-sucrose (HAM–S) reaching 5.5 cm diam. in 14 days at 25 °C. After two weeks of incubation with irregular margin, smooth surface, cottony, puffy, umbonate to pulvinate, white (1A1-2) towards margin, pinkish-white at centre (7A2), rosy vinaceous with age, raised, sometimes reaching about 1 cm high, and touching upper lid of Petri plates. Reverse light yellow to pale orange (4A4–5A3) towards centre, yellowish-white (4A2) towards margin, wrinkled; hyphae septate, unbranched to branched, pigmented, smooth and thin walled 2.5–4.35 µm wide.

Material examined: INDIA, Maharashtra, Pune District, on live Mantispa sp. (Mantispidae) 30 August 2012, P.N. Singh; (AMH 9760 holotype-dried colony on PDA); ex-type living culture, NFCCI 3970, National Fungal culture Collection of India-WDCM 932);

GenBank Numbers ITS:KU983517; TEF1:KU983516.

Notes: Colony characters and growth rates of E. indica vary when grown on HAM medium supplemented with different carbon sources, viz., arabinose, galactose, glucose, glycerol, fructose, lactose, maltose and sucrose (Fig. 106). Arabinose favored maximum radial growth of colony (56–60 mm) on pre-defined incubation conditions of 25 °C, and for 14 days, followed by galactose (55–56 mm), lactose (54–56 mm), sucrose (52–55 mm). Colony characters and growth pattern of E. indica resembles colony characters of E. kintrischica, but the growth rate was faster in E. indica compared to E. kintrischica on most of the carbon sources used in present study. In addition, E. indica and E. kintrischica expressed very prominent wrinkles on reverse sides of the colony on glucose, glycerol, and sucrose. Evlachovaea indica expressed less prominent wrinkles on maltose compared to distinctly prominent in E. kintrischica. Both the species did not produce wrinkles on galactose and lactose. Besides, E. indica produced no wrinkles on fructose, while it has been reported prominent in E. kintrischica.

Evlachovaea indica is morphologically distinct in having smaller and slender conidiophores, and significantly larger conidia from the type species, E. kintrichica, and from Evlachovaea-like isolates group I and II (Humber et al. 2013) in having longer conidia and conidiogenous cells. However, length–width ratio of conidia (L/W 1.8–3.4) and conidiogenous cells (L/W 4.8–32.9) in E. indica is significantly greater as compared to L/W ratio of conidia (L/W 1.3–2.5) and conidiogenous cells (L/W 2–7) of E. kintrichica. Proposed species is also distinct from type species in lacking synnemata and triangular or pomegranate like conidia (Borisov and Tarasov 1999).

The internal transcribed spacer (ITS)-rDNA and translation elongation factor (TEF1) regions have been shown to be taxonomically and phylogenetically informative for various entomopathogenic fungi such as Beauveria, Cordyceps, Isaria, Metarhizium and Paecilomyces (Liu et al. 2002; Luangsa-ard et al. 2005). These two gene sequences were also found to be useful in unambiguously placing the proposed isolate in a unique place in the phylogenetic trees. Though, it shows some level of relatedness with Evlachovaea-like isolates group I, is still distinct from Evlachovaea-like isolates group I, II, and Evlachovaea kintrischica. The phylogenetic analysis clearly establishes Evlachovaea indica as a novel species. Humber et al. (2013), utilized above mentioned genes to place the evlachovaea-like Brazilian isolates to Cordycipitaceae. However, they could not determine the correct species identifications, possibly due to the unavailability of TEF1 and other gene sequences of species of Isaria and other allied taxa. This indicates that a comprehensive analysis of more of genes, in addition to, ITS and TEF1 and their phylogenetic analysis needs to be undertaken to resolve the phylogenetic ambiguity of this group of fungi. Until the phylogenetic ambiguity is resolved, the present isolate is placed as a novel species under the genus Evlachovaea Borsov and Tarasov. To our knowledge, this fungus was isolated for the first time from a four-winged live Mantispa sp. collected from Western Ghats region in India. Moreover, this genus is being reported for the first time from India.

Helvella L. 1753

Species of Helvella L. are widely distributed in the northern hemisphere (e.g. Hyde et al. 2016; Zhao et al. 2015, 2016a, b, c). Since Linnaeus (1753) proposed the generic name Helvella, numerous studies have been conducted to address the taxonomic issue and infrageneric division in Asia, Europe and North America (e.g. Dissing 1966; Weber 1972; Häffner et al. 1987; Abbott and Currah 1997; Hyde et al. 2016; Zhao et al. 2015, 2016a, b, c).

Asexual morph Undetermined.

Habitat: Scattered or gregarious on soil in coniferous forests.

Distribution: Europe (Dissing 1966; Häffner et al. 1987); North America (Abbott and Currah 1997).

Material examined: CHINA, Yunnan Province, Panlong County, under Pinus spp., alt. 2000 m, 10 July, 2014, Qi Zhao 1643 (HKAS 87704, reference specimen designed here), Qi Zhao 1645 (HKAS 87706).

Notes: Helvella costifera has a greyish hymenium, pubescent receptacle surface with blunt edged ribs and a non-lacunose stipe, pleurorhynchous asci, broadly ellipsoid ascospores 15–19 × 10–13(–13.5) µm, slightly enlarged paraphyses (6–7 µm), and ectal excipulum J⁺ in Melzer’s reagent. Helvella costifera can be confused with H. acetabulum, which also have cupulate pileus and ribbed stipe (Dissing 1966; Häffner et al. 1987; Abbott and Currah 1997). However, H. acetabulum is distinguished by its brownish cup-shaped pileus and ribbed or lacunose stipe, with ribs reaching to the half or to the receptacle surface edge (Abbott and Currah 1997).

Helvella crispoides Q. Zhao & K.D. Hyde, sp. nov.

Index Fungorum number: IF 551935; Facesoffungi number: FoF 01338, Fig. 108

Etymology: crispoides is proposed because of the eastern Asian mushroom’s similarity to Helvella crispa.

Holotype: HKAS 90535

Sexual morph Pileus irregularly lobed to saddle-shaped, up to 4 cm high, 1–3 cm broad; margin inflexed to receptacle surface when young, expanded at maturity; hymenium undulate-rugose, cream, becoming brownish-yellow when dried; receptacle surface pubescent, with blunt ribs covering almost 1/3 of the pileus, grey, becoming greyish when dried.

Asexual morph Undetermined.

Habitat: Solitary or gregarious on the ground. In northern Thailand in conifer forest dominated by Pinus kesiya, and in southwestern China in conifer forest dominated by P. yunnanensis Franch.

Distribution: Only known from Eastern Asia.

Material examined: THAILAND, Chiang Mai Province, Chiang Mai County, Mushroom Research Center, in coniferous forest dominated by Pinus kesiyi, alt. 640 m, 31 August 2015, Qi Zhao 2661 (HKAS 90535, holotype). CHINA, Yunnan Province, Yulong County, alt. 1840 m, 21 Aug 2010, Q. Zhao 8292 (HKAS 69968).

Notes: Gross morphological differences between H. crispoides and H. pseudoreflexa Zhao et al. (2015) are subtle, the broad medullary excipulum of H. crispoides is usually 280–450 µm, while in the latter species it is generally 200–280 µm. The main differences between them are probably their ecological preferences, H. crispoides is associated with coniferous forests, while H. pseudoreflexa is mainly distributed in deciduous forests (Zhao et al. 2015). Both H. crispoides and H. papuensis Weber exhibit an irregular saddle-shaped pileus, which is deeply ribbed, with cross-veins and stipe pockets. However, H. papuensis is a tropical species originally described from Papua New Guinea, in the southern hemisphere by Dissing (1979). It is diagnosed by oxide yellow to brownish-yellow hymenium, with a villose to tomentose sterile surface which is concolorous or slightly darker than the hymenium surface (Dissing 1979). Helvella crispoides has a cream hymenium and a grey, pubescent, receptacle surface.

Sarcoscyphaceae Le Gal ex Eckblad

Cookeina Kuntze

Cookeina is a genus of cup fungi in the family Sarcoscyphaceae, members can be found in tropical and subtropical regions of the world. Species in the Cookeina have a deep, cup-shaped to funnel-shaped fruiting bodies, or apothecia, may be found on fallen branches of angiosperms, trunks, and sometimes on fruits (Weinstein et al. 2002) (Fig. 109).

Cookeina tricholoma (Mont.) Kuntze, Revis. gen. pl. (Leipzig) 2: 849 (1891)

Facesoffungi number: FoF 3136, Figs. 110, 111

Apothecia deeply cup-shaped, 4–16 mm diam. and up to 43 mm high, more or less long stalked, funnel-shaped. Hymenial surface smooth, pale yellow-orange or pale pink-orange to orange-reddish. Outer surface covered with long, whitish or very faintly orange brown hairs (1–2 μm diam.), obviously denser at the margin, grouped in bundles, concolorous to the hymenial surface, sometimes rough; margin smooth, whole, often introflexed. Stalk cylindrical, long, slightly expanded at the top, about 3 mm diam., smooth, white-cream. Flesh whitish or very pale whitish-orange, waxy. Ascospores variable in size, 33–36 × 13–16 μm, fusiform, few irregularly citriform, occasionally with slightly mucronate extremities, with 10–20 longitudinal thin striations, straight and more or less parallel, wall up to 2–3 μm thick, usually with a large cylindrical-ellipsoidal oil drop, rarely 2 oil-drops, hyaline, uniseriate in the asci. Asci 300–400 × 15–20 μm, 8-spored, cylindrical, wall 1–2 μm thick, with rapidly tapered base that ends in a thin and usually curved appendage 15–35 μm long, not amyloid, suboperculate. Paraphyses 2–3 μm diam., thread-like, cylindrical, simple or pluri-forked. Subhymenium not noticeable. Medullar excipulum 230–300 μm thick; textura intricata, hyphae of 6–9 μm diam., interwoven, variously anastomosed, septate, hyaline or slightly yellowish. Ectal excipulum 300–350 μm thick; textura globulosa, cells 18–30 μm diam., rounded, rarely angular, globose or slightly ellipsoidal, wall thin or somewhat thickened, grey-brown or pale brown. Presence of catenulate marginal cells, apex irregularly shaped or enlarged. Hairs up to 260 μm long, 40–50 μm large at the apex and 100–150 μm at the base, arising from the medullar excipulum, formed by more or less parallel fenced hyphae 10–15 μm wide, cylindrical or slightly enlarged in some points, with rounded, capitulate tip, irregularly thickened in some points, wall 2–4 μm thick, septate, yellow–brown, less dense near the top and more numerous and shorter near the base.

Habit, habitat and distribution: as groups of more or less close fruit-bodies, usually on dead or decaying wood, May–August. Our collection was collected on a decaying wood at Hanthana Mountains Range, Peradeniya.

Specimens examined: SRI LANKA, Kandy District, Hanthana Mountains Range, 19 June 2012, Samantha C. Karunarathna (MFLU 12-2390, reference specimen designated here).

GenBank Number ITS:KY649459.

Notes: The main distinguishing characteristics of C. tricholoma are pale yellow-orange apothecia and large ascospores. However, colorful C. sulcipes (Berk.) Kunze, are usually orange-red, cherry-red or scarlet, might be confused with C. tricholoma; its ascospores, although with the same kind of ornamentation, are smaller in size (25–30 × 11–14 μm). This is the first report of C. tricholoma with the molecular phylogenetic confirmation from Sri Lanka (Fig. 111). We therefore designate it as a reference specimen (sensu Ariyawansa et al. 2014b).

Agaricomycetes Doweld

Agaricales Underw.

Agaricaceae Chevall.

The family Agaricaceae was introduced by the French botanist François Fulgis Chevallier in 1826 (Chevallier 1826). Named after the type genus Agaricus, the family was originally circumscribed by Carl Linnaeus in 1753 in his work on Species Plantarum.

Amanita Pers.

The morphologically diverse and monophyletic genus Amanita Pers. (Persoon 1797; Bas 1969; Zhang et al. 2004; Wolfe et al. 2012b; Tulloss et al. 2016) is dominantly mycorrhizal however, at least one species is saprobic (Wolfe et al. 2012a) and another three dozen or so are non-mycorrhizal with precise trophic modes unclear. The genus is divided into two subgenera: Amanita subg. Amanita (with inamyloid spores) comprising three sections, viz sect. Amanita, sect. Caesareae Singer, sect. Vaginatae sensu Yang (1997) and A. subg. Lepidella (E.-J. Gilbert) Veselý emend. Corner & Bas (with amyloid spores) includes four sections namely, sect. Amidella (E. J. Gilbert) Konrad & Maubl., sect. Lepidella sensu Bas (1969), sect. Phalloideae (Fr.) Quél., and sect. Validae (Fr.) Quél. More than 530 species are described worldwide with valid accepted names and about 50 taxa are reported from India (Yang 2000; Bhatt et al. 2003; Tulloss and Yang 2016). Here, we describe two new species belonging to subg. Amanita sect. Vaginatae. They were collected from the northwestern Indian Himalayas and are presented here with morphological and molecular data. The respective single nrLSU gene tree is presented in Fig. 112.

Notes: The combination of macro- and micromorphological features such as inamyloid spores, saccate volva, absence of a bulb and absence of Basidia clamps place Amanita cornelii in Amanita [subg. Amanita] sect. Vaginatae sensu Yang (Yang 1997). In the field the present species is distinct from other known species of Amanita sect. Vaginatae by its pileus with coarse, irregular, radial, brown streaks. In eastern Asia, Amanita cornelii might be confused with Amanita brunneofuliginea Zhu L. Yang (Yang 1997) (originally described from China); however, the latter has a pileus that is blackish-brown to brownish-black over the centre. The latter also differs by lacking coarse, irregular, brown stripes on the pale background on the pileus, bearing a white to dirty white patches of universal veil on the pileus, its having a saccate volva which is dirty white with plentiful pale-leather to orange spots on its outer surface and by its subglobose to broadly ellipsoid basidiospores “(10–)10.5–13(–14) × (9–)9.5–12(–12.5) μm, (Q = (1.04–)1.06–1.24(–1.26); Q′ = 1.13 ± 0.06)” (Yang 1997). Amanita lignitincta Zhu L. Yang (Yang 1997) (originally described from China), is somewhat similar to the present taxon with a wood brown to leather brown pileus; but it differs by its slightly depressed pileus, a contrastingly darker ring–like zone at the inner end of its marginal striations, by its larger basidiospores “(9.5–)10–13(–13.5) × (8.5–)9–12(–13) µm” (Yang 1997) and by lacking the unusual striping pattern of the present species. Our nrLSU-tree clearly indicates the genetic dissimilarities of Amanita cornelii from six taxa. BLAST search indicates relative closeness (96% identity with 95% query coverage) of A. cornelii to A. friabilis (GenBank Numbers KU248120, KU248119); (96% identity to 96% query coverage) of A. cornelii to A. basiana (GenBank Numbers KP258987); (96% identity with 94% query coverage) of A. cornelii to A. affin. fulva (GenBank Numbers HQ539697); (96% identity with 95% query coverage) of A. cornelii to A. olivaceogrisea (GenBank Numbers KU867877); (95% identity to 95% query coverage) of A. cornelii to A. affin. ceciliae (GenBank Numbers KU139438, KU139439); (97% identity with 95% query coverage) of A. cornelii to A. populiphila (GenBank Numbers KP221314, KP221304).

The European A. basiana Tulloss & M. Traverso (Tulloss and Traverso 2000) and A. friabilis (Karst.) Bas (Bas 1974) are easily segregated from the present species because, in those two taxa, hyphae provide extensive and persistent interconnection between the pileipellis and the universal veil (Bas 1974; Tulloss and Traverso 2000, 2001). Moreover, A. friabilis is separated from A. cornelii by its subglobose to elongate spores “Q = (1.06–)1.13–1.62(–1.89); Q = 1.23–1.43; Q′ = 1.34” (www.amanitaceae.org/?Amanita%20friabilis); and A. basiana also differs from the present taxon due to its broadly ellipsoid to ellipsoid spores Q = (1.08–)1.13–1.44(–2.34); Q = 1.21–1.33(–1.36); Q′ = 1.27 (www.amanitaceae.org/?Amanita%20basiana).

Volval differences also serve to segregate species that could be mistaken for A. ceciliae (European) and A. olivaceogrisea (European) from the present species. It should be noted that many species in eastern Asia, eastern North America and other regions have been mistaken for A. ceciliae in the past. This group have friable volva’s that quickly become gray with age often leaving warts and small patches on the pileus, fragments on the lower stipe, and a white cupulate structure on the stipe’s base (Bas 1984; Tulloss 1994, 2001). Amanita olivaceogrisea also differs from Amanita cornelii by its subglobose to broadly ellipsoid spores showing slightly higher Q values, i.e. Q = (1.03–)1.04–1.14(–1.27); Q = 1.09–1.11; Q′ = 1.10 (www.amanitaceae.org/?Amanita%20olivaceogrisea).

Amanita affin. fulva (North America) possesses an orange-brown pileus that becomes paler at the margin and brown to dark brown in the center, lacks the irregular striping pattern of the present species, and has a white external volva surface that becomes orange-brown to rusty in numerous spots. The matching GenBank Numbers sequence is a nearly perfect match to sequences derived from Newfoundland material presently treated under a provisional name by Tulloss (www.amanitaceae.org/?Amanita%20daimonioctantes).

Amanita populiphila Tulloss & Moses (Tulloss and Moses 1995), described from North America differs from the present taxon by an unstriped, white to pale yellowish pileus that takes on rusty stains with time; cream-colored Lamellae having pale orange or pinkish tint; occurrence of plentiful lamellulae and a weakly structured, white volva that tends to change color as the pileus does. Amanita populiphila has only been recorded with species of Populus [cottonwood and aspen] and has subglobose spores with slightly higher Q values than that of the present taxon; Q = (1–)1.04–1.20(–1.61); Q = (1.06–)1.08–1.15(–1.19); Q′ = 1.11. (www.amanitaceae.org/?Amanita%20populiphila). Macro- and micromorphology coupled with the LSU-based genetic distances, segregate Amanita cornelii from previously known species of Amanita sect. Vaginatae.

Specimen examined: India, Uttararakhand, Rudraprayag, Hariyali Devi Forest, 1651 m, N3015.955′E7903.719′, 27 July 2015, T. Mehmood, TM 15-659 (CAL 1338, holotype).

GenBank Number ITS:KX539266.

Notes: The combination of macro- and micromorphological features such as longitudinally acrophysalidic stipe context; bilateral, divergent lamella trama, inamyloid spores, absence of a stipe bulb and absence of Basidia clamps place Amanita emodotrygon in Amanita [subg. Amanita] sect. Vaginatae Sensu Yang (Yang 1997).

In the field this species is distinct from other known species of Amanita sect. Vaginatae by its greyish-brown to olive campanulate pileus, which is deeply grooved towards the margin, crowded white lamellae that becomes pale yellowish with age and occurrence in a coniferous forest under Pinus roxburghii. Micromorphologically, presence of globose to subglobose spores, branched, septate and thick-walled, filamentous hyphae in the universal veil at the stipe base are also quite striking. Based on the key in Tulloss (1994) and (www.amanitaceae.org/?stirps%20Pachyvolvata), there is a group of North American and European taxa that are morphologically similar to A. emodotrygon in having a large, robust basidiome and universal veil-strips Pachyvolvata of Tulloss. The relevant section of the key is largely based on cap colour and spore size and shape. Two of the taxa are described as having an olivaceous tint to the cap. Two are described as having a ring around the inner ends of marginal striations. Hence, gross morphology of this group is similar to that of A. emodotrygon. One of the species has both the cited pileus characters and is, hence, most similar to the present taxon:

Amanita magnivolvata Aalto (1974) (originally reported from Finland) is segregated from A. emodotrygon by its gray ring on the inner edge of the marginal striations, white Lamellae becoming gray with age and a white exterior surface of the universal veil, developing small, rusty, yellow spots. It occurs in mixed forest including Alnus, Betula, and Picea in Scandinavia and has been reported from Italy (Liguria). Its spores are subglobose to broadly ellipsoid and have comparatively higher Q values than occur in the present taxon-Q = (1.03–)1.06–1.36(–1.52); Q = 1.18. (www.amanitaceae.org/?Amanita%20magnivolvata)

Our nrLSU-tree clearly indicates the genetic dissimilarities of Amanita emodotrygon from three taxa. BLAST search indicates relative closeness (98% identity with 98% query coverage) of Amanita emodotrygon to Amanita trygonion (GenBank Numbers KU186810); (94% identity with 94% query coverage) of Amanita emodotrygon with Amanita penetratrix (GenBank Numbers KU186834, KU186833, KU186832, KU186831); (93% identity to 93% query coverage) of Amanita emodotrygon to Amanita myrmeciae (GenBank Numbers KU852505 and KU186806).

The relatively small number of taxa that have been sampled for nrLSU in section Vaginatae and the great difficulty in dealing with the genus by morphological means alone create an unusual situation in the present case, i.e. all of the sequences for which close BLAST comparisons exist in the case of A. emodotrygon are taxa described provisionally. Hence, we can say, at the time of writing, the present taxon is quite distinct from all published species of sect. Vaginatae for which sequence data exists.

Amanita trygonion Tulloss, Pastorino & Kudzma, nom. prov. is a small gray species of the sandy coastal plain in southeastern Texas, USA, where it occurs in Pinus dominated mixed forest and has subglobose to broadly ellipsoid spores with higher Q values than those of the present taxon-Q = (1.05–)1.10–1.33(–1.40); Q = 1.17–1.20; Q′ = 1.19. (www.amanitaceae.org/?Amanita%20trygonion)

Amanita penetratrix Tulloss & Kudzma, nom. prov. is a large species with a hard-fleshed, prominent umbo in the center of a gray to gray-brown to white pileus. It is known from a few sites in the northeastern USA. It occurs in mixed forest including Pinus strobus, Betula, Fagus, and Quercus and has spores that are dominantly subglobose to broadly ellipsoid with higher Q values than those of the present taxon-Q = (1.04–)1.05–1.25(–1.34); Q = 1.09–1.16; Q′ = 1.12. The primordium of this mushroom develops deep in forest soil. The unusual umbo allows penetration of up to 154 mm of soil dense with roots and is reminiscent of the perforatorium of species of Termitomyces. (www.amanitaceae.org/?Amanita%20penetratrix)

Amanita myrmeciae Tulloss, Kudzma & Albertella, nom. prov. is known only from association with eucalypts in the Blue Mountains of New South Wales, Australia. This species is unique among those discussed here by being a significant food source for ants of the genus Myrmecia. The species is known from one specimen with a light brown to brown pileus 62 mm wide and has subglobose spores with slightly higher Q values than those of the present taxon—Q = 1.06–1.18; Q 1.10.

Notes: Lepiota microspila, a species from Sri Lanka is similar to L. maerimensis in its ochraceous tawny to rufous squamules on the pileus and stipe covering. Lepiota microspila differs from L. maerimensis in having a smaller spore size (3.3–4.5 × 1.7–2.3 (3.8 × 2) µm, shorter Basidia (6.5–8 × 3.3.5 µm), and thicker wall of elements in the pileus covering (up to 1 µm). Unfortunately, Cheilocystidia of Lepiota microspila were not recovered in the Sri Lankan material (Pegler 1972). Some species of section Echinatae from India are compared with this species, for example Natarajan and Manjula (1982) described Lepiota subrufa from South India and it differs from L. maerimensis in its pale red background on the pileus and stipe, and reddish-brown pyramidal squamules, pastel red Lamellae and dull red membranous annulus. Lepiota babruka is also similar to L. maerimensis in having brown to dark brown pyramidal squamules on the pileus, but it differs in lacking a squamulose stipe and yellowish-white to pale yellow lamellae (Arun Kumar and Manimohan 2009) (Fig. 121).

Leucocoprinus Pat.

Leucocoprinus belongs to the family Agaricaceae. Its best-known member is the yellow pot-plant mushroom Leucocoprinus birnbaumii, found worldwide. The type species of this genus is L. cepistipes (Sowerby) Pat.

Pileus 3–6 cm broad, hemispherical when young, expanding to planoconvex to campanulate, margin decurved, slightly sulcate-striate, when young with many, dense, soft floccules, readily collapsing or wearing off to leave farinose covering; light buff to white at center, white elsewhere. Lamellae distantly free, rather broad, thin; white, edge slightly fimbriate. Stipe 5–8 cm long, 4–6 mm broad at apex, gradually enlarged downward to a broadly clavate to somewhat fusiform 6–14 mm broad base; sometimes coarsely farinose to slightly flocculose-farinose below annulus, subfarinose above; white to ivory yellow tinted. Annulus white, very soft, rather flaring, median to superior. Basidiospores 8–11 × 5–8 μm, Q = 1.32–1.47, metachromatic, dextrinoid, ellipsoid to amygdaliform, thick-walled, with an apical germ pore covered with a hyaline lens. Basidia 16–22 × 9–12 μm, pyriform to clavate with a bulbous base, 4-spored, surrounded by 4 pseudoparaphyses. Sterigmata 1–2 × 0.7–1.5 μm. Pseudoparaphyses 10–13 × 7–10 μm, sphaeropedunculate to broadly clavate to pyriform, very broad point of attachment. Cheilocystidia 27–75 × 7–18 μm, thin-walled, hyaline, subcylindrical to narrowly fusiform to slightly narrowly lageniform, mucronate, rarely obtuse, moderately pedicellate. Pileus covering a sparse layer of terminal cells essentially absent on mature pilei, most prevalent near the center of young pilei, 45–117 × 7–9 μm, cylindrical to narrowly lageniform, with flexuous necks. Stipe covering structure like that of pileus, with terminal cells even more sparse. Stipitipellis a cutis of narrowly cylindrical, 5–8 μm broad elements. Clamp connections absent.

Entolomataceae Kotl. & Pouzar

Entolomataceae is a large family of pink-spored terrestrial gilled mushrooms introduced by Kotl. and Pouzar in 1972 and typified by Entoloma. The family is highly variable in terms of sporocarp morphology and micromorphology (Noordeloos 2004). This family contains four genera and 1071 species (Kirk et al. 2008).

Entoloma Fr. ex P. Ku mm.

The genus Entoloma is characterized by pink or pinkish-brown spore print and basidiospores that are angular in all views (Noordeloos 1992; Noordeloos and Gates 2012). There is no agreement regarding the limits of the genus Entoloma as some authors have set a very wide limit to the genus (e.g. Donk 1949; Romagnesi 1978; Noordeloos 1981, 1992, 2004; Co-David et al. 2009; Noordeloos and Gates 2012) and others have applied a very restricted concept of the genus and have introduced several segregate genera such as Alboleptonia, Claudopus, Inocephalus, Leptonia, Nolanea, and Pouzarella (e.g. Largent 1974; Mazzer 1976; Baroni et al. 2011). In the course of a continuing study on the Entolomataceae of Kerala State, India, we came across a species of Entoloma, which was found to be new to science. It is herein formally described as new based on both morphology and molecular phylogeny. Maximum likelihood analysis placed the new species within a clade that represents the subgenus Entoloma with significant (74%) ML bootstrap support (Fig. 125).

Entoloma magnum K.N.A. Raj & Manim., sp. nov.

MycoBank number: MB 818742; Facesoffungi number: FoF02637; Figs. 126, 127

Etymology: The specific epithet refers to the large size of the basidiocarp.

Holotype: CAL 1385

Basidiocarp large, tricholomatoid. Pileus 102 mm diam., somewhat plano-convex with a low central umbo surrounded by a shallow depression; surface dark brown (7F4/OAC636) at the centre and light brown (7D4/OAC659) towards the margin, not hygrophanous, tacky, finely radially wrinkled, innately fibrillose, plicate-striate towards the margin; margin somewhat incurved to almost straight, finely crenate, fissile. Lamellae narrowly adnate to adnate, moderately crowded, subventricose, orange white (6A2/OAC634), up to 13 mm wide, with lamellulae of 3 lengths; edge crenate to somewhat wavy, concolorous with the sides. Stipe 99 × 18 mm, central, terete, slightly tapering towards both the apex and the base, robust, solid; surface yellowish-brown (5D4/OAC743) towards the apex, whitish towards the base, appressed-fibrillose all over; base with scanty basal mycelium. Odour and taste not distinctive.

Basidiospores 7–10 × 7–9 (8.6 ± 0.73 × 7.6 ± 0.66) µm, Q = 1–1.2, Qm = 1.13, predominantly pentagonal or occasionally 4- or 6-angled in profile, isodiametric to sub-isodiametric, hyaline, thick-walled. Basidia 31–57 × 9–11 µm, clavate, hyaline, thin-walled, 4-spored; sterigmata up to 7 µm long. Lamella-edge fertile. Cheilocystidia and pleurocystidia absent. Lamellar trama subregular; hyphae 4–7 µm wide, pale brownish-yellow, thin-walled. Subhymenium inconspicuous. Pileus trama subregular; hyphae 7–13 µm wide, pale yellow, thin-walled. Pileipellis a transition between an ixocutis and an ixotrichoderm; hyphae 5–10 µm wide, with a pale brownish-yellow wall pigment, thin-walled. Stipitipellis a cutis rarely disrupted with flaring out hyphae; hyphae 5–12 µm wide, pale brownish-yellow, thin-walled. Caulocystidia absent. Oleiferous hyphae present in both lamellar and pileus trama. Clamp connections observed on all hyphae.

Habitat: on soil, among litter, solitary.

Material examined: INDIA, Idukki District, Munnar, Eravikulam National Park, 6 July 2011, K.N. Anil Raj AR683 (CAL 1385, holotype).

GenBank Number ITS:KY002062.

Notes: Entoloma magnum is characterized by a large, tricholomatoid basidiocarp; a brown-coloured, umbonate pileus; adnexed to narrowly adnate lamellae; a fleshy-fibrous stipe; isodiametric to sub-isodiametric basidiospores; absence of cheilocystidia; a pileipellis that is a transition between an ixocutis and an ixotrichoderm and the presence of clamp connections on all hyphae. Owing to these characters, E. magnum fits into the section Entoloma of the subgenus Entoloma (Noordeloos 2004; Co-David et al. 2009; Noordeloos and Gates 2012).

Entoloma brihadum Manim., A.V. Joseph & Leelav., a species previously described from Kerala (Manimohan et al. 1995), somewhat resembles E. magnum in having robust, tricholomatoid basidiocarps with a subumbonate pileus, crowded lamellae, a fertile lamella-edge, and absence of caulocystidia. However, E. brihadum has a smaller (50 mm), pinkish-white, glabrous pileus with pellucid striations, free to adnexed lamellae, a pinkish-white, and glabrous stipe, smaller and exclusively quadrate basidiospores (6–8 × 6–7 µm) and a cutis-type pileipellis composed of hyaline hyphae.

Entoloma myochroum Noordel. & E. Ludw., a species from Germany (Noordeloos 2004), is close to E. magnum in having almost similar-sized basidiocarps, a concave and glabrous pileus, adnate lamellae with concolorous edges, a solid stipe with a fibrillose surface, almost similar-sized basidiospores (7–10 × 6.5–8.5 µm) with 4–6 angles, a fertile lamella-edge and clamped hyphae. However, that species has a mouse-grey-coloured pileus, a flexuous or irregularly shaped stipe, a cutis-type pileipellis made up of hyphae with intracellular pigment and lamellar and pileus trama with short inflated elements.

In a BLASTn search using the ITS sequence (628 bp) derived from E. magnum, the closest hit was E. ochreoprunuloides (GenBank Number KC710092; 92% identity). Entoloma ochreoprunuloides Morgado & Noordel., is a species from Germany (Noordeloos 2004; Morgado et al. 2013), resembles E. magnum in having a similar-shaped, brownish pileus with radially wrinkled and innately fibrillose surface, isodiametric basidiospores, a fertile-lamella edge, and clamped hyphae. However, E. ochreoprunuloides differs from E. magnum owing to its smaller-sized and differently-coloured basidiocarps, emarginate lamellae, smaller (5.9–7.1 × 5.7–7.2 µm) basidiospores and hyphae of the pileipellis with intracellular pigment.

In the phylogram (Fig. 126) generated from the ML analysis, E. magnum nested within a clade, which represents the subgenus Entoloma. Within this clade, E. magnum, E. luteobasis, E. ochreoprunuloides, E. madidum and collections of E. bloxamii formed a subclade. Within this subclade, E. magnum was differentiated as an independent lineage separated from other species with significant (74%) bootstrap support.

Inocybaceae Jülich

The type genus of the Inocybaceae, Inocybe, had traditionally been placed within the Cortinariaceae family (Kirk et al. 2008, Singer 1986). Despite this, Jülich placed the genus in its own family, the Inocybaceae (Jülich 1982). Members of this family have a widespread distribution in tropical and temperate areas (Cannon & Kirk 2007).

Inocybe (Fr.) Fr.

The genus Inocybe (Inocybaceae) is a species-rich genus of Agaricales and is well-known for their ectomycorrhizal ecology and toxicity of most species (Matheny 2009). Matheny (2009) proposed seven major clades or lineages consisting of Inocybe and its allies within the family Inocybaceae. Of the seven clades or lineages (Inocybe s. str., Nothocybe, Pseudosperma, Mallocybe, Inosperma, Auritella and Mallocybella), Auritella and Mallocybella were formally recognised as distinct genera, Auritella and Tubariomyces (Matheny and Bougher 2006a, b; Alvarado et al. 2010). Species of Inocybe are characterised by mostly brownish or rarely whitish basidiomata occasionally with a purplish or lilac hue, a fibrillose-rimose or squamulose pileus, brownish lamellae, brown spore-print, a fibrillose-pruinose stipe at times with a distinct marginate-bulbous base, a characteristic odour, smooth, warty, nodulose or spinulose basidiospores and metuloidal cystidia often with crystalloid deposits at their apices. Several species are devoid of metuloidal cystidia and they are characterised by abundant, thin-walled cheilocystidia (Matheny 2005; Larsson et al. 2009). During the course of our studies on this genus in Kerala State, India, we discovered several new species of Inocybe. Three of these species belonging to the Pseudosperma clade (Fig. 128) are described here.

Inocybe brunneosquamulosa K.P.D. Latha & Manim., sp. nov.

MycoBank number: MB 816735; Facesoffungi number: FoF: 2176, Figs. 129, 130

Etymology: referring to the brown squamules on the pileus surface.

Holotype: CAL 1308

Basidiocarps small. Pileus 7–11 mm diam., convex with a small umbo when young, becoming broadly convex still with a small umbo at maturity; surface initially dark brown (6F8/OAC636) on the squamules and brownish-orange (6C4/OAC653) elsewhere, becoming dark brown (6F7/OAC637) on the squamules, greyish-orange (6B3/OAC633) on the fibrils and brownish-grey (6C2/OAC662) elsewhere at maturity, appressed- to recurved-squamulose all over when young, becoming appressed- to recurved squamulose on and around the umbo and appressed-fibrillose and rimose towards the margin; margin incurved, becoming decurved, crenate or wavy.

Basidia 21–30 × 11–13 µm, clavate, thin-walled, hyaline, 4-spored; sterigmata up to 4.5 µm long. Pleurocystidia absent. Lamella-edge heterogeneous. Cheilocystidia 17–39 × 11–18 µm, versiform: clavate, utriform, fusiform, cylindrical with an obtuse apex, occasionally subglobose or rarely pedicellate or septate, hyaline with faint hyaline encrustations, thin- to slightly thick-walled. Lamellar trama subregular; hyphae 6–15 µm wide, thin-walled, hyaline or pale yellow. Subhymenium pseudoparenchymatous. Pileus trama subregular, composed of both narrow and inflated hyphae; hyphae 3–30 µm wide, pale yellow, thin-walled.

Habitat: on the ground, scattered around Vateria indica (Dipterocarpaceae) trees.

Specimen examined: INDIA, Kerala State, Ernakulam District, Kochi, Thevakkal, Ponnakkudam Kavu sacred grove, 25 August 2014, K.P.D Latha DKP264 (CAL 1308, holotype).

GenBank Numbers ITS: KX073582; LSU: KX073586; RPB2: KX073589.

Notes: Small basidiocarps with a dark brown, squamulose and fibrillose-rimose pileus; a fibrillose stipe with a finely pruinose apex and an abruptly ending base; smooth, ellipsoid to subphaseoliform basidiospores; a hymenium devoid of pleurocystidia; versiform cheilocystidia with occasional, faint, hyaline encrustations; a cutis-type pileipellis which is disrupted with trichodermal patches and a cutis-type stipitipellis disrupted by loose, hyphal projections and often with caulocystidia at the extreme stipe apex are the salient features of I. brunneosquamulosa. Inocybe fuscospinulosa, a species originally described from Indonesia (Horak 1980b) and also reported from Sri Lanka (Pegler 1986), seems to be somewhat similar to I. brunneosquamulosa in having a pileus of rather similar colour and surface features, a fimbriate lamella-edge, a fibrillose stipe, a hymenium devoid of pleurocystidia, a trichoderm-type pileipellis and the presence of cheilocystidia. Inocybe fuscospinulosa, however, is distinguished from the I. brunneosquamulosa in having larger basidiocarps with a densely squamulose pileus, crowded, adnexed, tobacco brown lamellae, a reddish-brown tinted stipe with occasional scales, smaller (6.5–8 × 4–5 µm) and ovoid basidiospores, cylindric to subfusoid cheilocystidia devoid of encrustations and a stipitipellis lacking caulocystidia. Inocybe brunneosquamulosa is also somewhat similar to I. umbrinovirens E. Horak, a species so far known only from Papua New Guinea (Horak 1980b), in having a somewhat similar-coloured pileus with almost similar surface features, a fibrillose stipe, smooth basidiospores, a hymenium devoid of pleurocystidia, the presence of cheilocystidia with encrusting pigment and a trichoderm-type pileipellis. However, the characters such as the larger basidiocarps with differently-shaped pileus, chocolate brown, adnexed, crowded lamellae, a hollow stipe with a greenish base, larger (10–12.5 × 7–8.5 µm) and ovoid basidiospores, larger basidia, cheilocystidia that are terminal elements of lamellar trama, the absence of caulocystidia and a strong odour make I. umbrinovirens different from I. brunneosquamulosa.

Inocybe squamata J.E. Lange, a species widespread in Europe and USA (Cripps 1997) and also reported from Kerala (Pradeep and Vrinda 2010; Mohanan 2011) is similar to I. brunneosquamulosa in having a pileus of somewhat similar texture, rather similarly attached lamellae, a fibrillose stipe, subphaseoliform basidiospores, a hymenium devoid of pleurocystidia, the presence of cheilo- and caulocystidia and similar type of pileipellis. However, I. squamata has larger basidiocarps with a differently-coloured pileus, thick, broad, yellow brown lamellae, a longer, white stipe, larger basidiospores (9–11.5 (13) × (5) 5.5–6.5 µm), occasional 2-spored basidia and narrowly clavate cheilo- and caulocystidia lacking encrustations.

Comparison of the ITS (679 bp), LSU (935 bp) and RPB2 (699 bp) sequences derived from I. brunneosquamulosa with the nucleotide sequences available in GenBank Numbers showed that I. brunneosquamulosa has distinct sequences. Inocybe species MCA562 resulted as the closest hit in megablast searches with ITS (GenBank Numbers JQ408785; Identities = 630/682 (92%)), LSU (GenBank Numbers JN975016; Identities = 921/936 (98%)) and RPB2 (GenBank Numbers JQ421077; Identities = 673/699 (96%)) sequences. Inocybe species MCA562 is a collection from Japan, but its morphological features are unavailable for comparison as it remains unpublished.

The phylogenetic placement of I. brunneosquamulosa is shown in the phylogram (Fig. 128) generated from the ML analysis of RPB2 sequence data matrix. In the ML analysis, I. brunneosquamulosa nested in the Pseudosperma clade with maximum support (100% ML) where it paired with Inocybe species MCA562 and had a strong support (96% ML).

Inocybe palaeotropica, however, has larger basidiocarps with dissimilar colour and surface features, adnexed lamellae, a fibrillose stipe devoid of apical pruinosity, ovoid to short ellipsoid basidiospores, only 4-spored basidia, clavate to cylindro-clavate cheilocystidia, hyphae of lamellar trama lacking encrustations, a cutis-type pileipellis and smaller, cylindro-clavate caulocystidia. Inocybe luteobrunnea is somewhat similar to I. fuscospinulosa Corner & E. Horak, an Indonesian species (Horak 1980b) and also reported from Sri Lanka (Pegler 1986), in having a somewhat similar-shaped pileus, a fibrillose stipe, almost similar-sized basidiospores (6.5–8 × 4–5 µm), cheilocystidia, a hymenium devoid of pleurocystidia and an almost similar pileipellis structure. However, I. fuscospinulosa differs from I. luteobrunnea owing to its larger basidiocarps with conspicuous, erect, spiny squamules on the pileus, crowded, adnexed, tobacco-brown lamellae, a red-brown tinged stipe with occasional brown squamules and without a distinct bulbous base, ovoid basidiospores, consistently 4-spored basidia, larger, differently-shaped cheilocystidia and a stipitipellis devoid of caulocystidia.

The distinctive status of (CAL 1260: 675 bp; CAL 1261: 674 bp), LSU (CAL 1260: 838 bp; CAL 1261: 746 bp) and RPB2 (CAL 1260: 651 bp) sequences of I. luteobrunnea was confirmed in the BLASTn searches. An unnamed Australian species, Inocybe species AU95 was the closest hit in a megablast search for ITS (GenBank Numbers KP636851; Identities = 540/588 (92%)), LSU (GenBank Number KP171053; Identities = 831/839 (99%)) and RPB2 (GenBank Number KM555145; Identities = 638/651 (98%)) sequences.

The phylogram generated from the Maximum Likelihood (ML) analysis (Fig. 129) depicts the relative placement of I. luteobrunnea. The ML analysis placed I. luteobrunnea in the Pseudosperma clade with full support (100% ML) based on RPB2 sequence data matrix. Within this clade, I. luteobrunnea clustered with an unnamed Australian species, Inocybe species AU95 (KM555145) with maximum support (100% ML). The macro-morphological and microscopic data of that species are not available for comparison.

MycoBank number: MB 816736; Facesoffungi number: FoF: 2175; Figs. 133, 134

Etymology: referring to the reddish-brown colour of the pileus.

Holotype: CAL 1307

Basidiocarps small. Pileus 6–12 mm diam., somewhat hemispherical or paraboloid when young, becoming convex or plano-convex with a small umbo; surface reddish-brown (8E5, 8E6/OAC609, OAC610) when young, becoming dark brown (7F7/OAC621) at the centre and on the squamules, orange grey (6B2) elsewhere, appressed- to slightly recurved squamulose and appressed-fibrillose all over when young, becoming appressed- to recurved squamulose on and around the centre, appressed-fibrillose and rimulose towards the margin; margin initially incurved, becoming decurved to somewhat straight with age, crenate. Lamellae sinuate or emarginate, close, initially greyish-orange (6B3/OAC654), becoming brownish-orange (6C4/OAC695), up to 1.5 mm wide, with lamellulae of 3 lengths; edges fimbriate, whitish. Stipe 11–20 × 1–2 mm, central, terete, equal or slightly tapered towards the base, cartilaginous, solid; surface brownish-orange (6C3/OAC633), fading towards the apex, appressed-fibrillose all over, slightly pruinose at the apex; base slightly enlarged. Odour and taste not distinctive.

Basidiospores 7–9 × 5–6 (8.32 ± 0.63 × 5.57 ± 0.43) µm, Q = 1.2–1.7, Qm = 1.4, smooth, ellipsoid to slightly phaseoliform, slightly thick-walled, pale yellowish-brown. Basidia 18–27 × 9–12 µm, clavate, thin-walled, hyaline, 4-spored; sterigmata up to 3 µm long. Pleurocystidia absent. Lamella-edge heterogeneous. Cheilocystidia 17–44 × 6–15 µm, abundant, versiform: narrowly clavate, clavate, cylindrical, oblong, ellipsoid, fusiform, obovoid, cylindrical with a median constriction or with a subcapitate apex, occasionally septate, exuding some amorphous material at the apex, slightly thick-walled (up to 1 µm thick), hyaline or rarely with pale yellowish-brown, amorphous contents, occasionally with faint, hyaline encrustations. Lamellar trama subregular, composed of both narrow and inflated hyphae; hyphae 3–23 µm wide, thin- to slightly thick-walled, hyaline. Subhymenium pseudoparenchymatous. Pileus trama subregular; hyphae 6–27 µm wide, hyaline or pale yellow, thin-walled. Pileipellis a cutis often disrupted with bundles of tangled ascending hyphae towards the centre; hyphae 5–10 µm wide, with a pale brownish-yellow wall pigment and brown spiral encrustations. Stipitipellis a cutis composed of hyaline or pale yellow hyphae (3–10 µm wide), devoid of encrustations, frequently disrupted by bundles of loose, tangled hyphae towards the apex (2–6 µm wide), with a pale-yellow wall pigment and pale yellow spiral encrustations, thin- to slightly thick-walled, occasionally with yellowish-brown amorphous contents. Caulocystidia absent. Clamp connections observed on all hyphae.

Habitat: on soil, solitary or in small groups, near Hopea ponga (Dipterocarpaceae) trees.

Specimen examined: INDIA, Kerala State, Wayanad District, Muthanga, Muthanga Wildlife Sanctuary, 21 August 2013, K. P. Deepna Latha DKP142 (CAL 1307, holotype).

GenBank Numbers ITS:KX073583; LSU:KX073587; RPB2:KX073590.

Notes: Small basidiocarps with an appressed-fibrillose to squamulose pileus; a stipe with a slightly enlarged base and a fibrillose surface; smooth, ellipsoid to slightly phaseoliform basidiospores; a hymenium devoid of pleurocystidia; versiform cheilocystidia exuding some amorphous material at the apex; a cutis-type pileipellis disrupted with bundles of tangled ascending hyphae; and a cutis-type stipitipellis often disrupted by bundles of loose, tangled hyphae towards the apex are the diagnostic features of I. rubrobrunnea.

Following the key of Kobayashi (2002), I. rubrobrunnea keys out close to I. quercina Hongo, a species known from Japan, because of its reddish-brown pileus with almost similar size, shape and surface features, a whitish lamella-edge, a solid stipe with a fibrillose surface, almost similar-shaped basidiospores, the absence of pleurocystidia and the presence of cheilocystidia. However, the characters such as the adnexed lamellae that become red when cut, a longer stipe, larger basidiospores (8.2–10.8 × 4.8–5.5 µm) and basidia, smaller cheilocystidia devoid of encrustations, a cutis-type pileipellis lacking encrustations, the presence of caulocystidia and a strong odour of that species make it different from I. rubrobrunnea. Inocybe fuscospinulosa, a species originally described from Indonesia (Horak 1980b) and also reported from Sri Lanka (Pegler 1986), has a pileus with dark brown squamules, a whitish lamella-edge, basidiospores of similar size (7–9 × 4.2–5.5 µm) and shape and the absence of pleuro- and caulocystidia. However, that species differs in having larger basidiocarps with a campanulate to applanate pileus, a white context discolouring purplish-red on exposure, cheilocystidia devoid of encrustations and a trichoderm-type pileipellis.

Comparison of the ITS (676 bp), LSU (924 bp) and RPB2 (702 bp) sequences of I. rubrobrunnea with the nucleotide sequences of taxa available in GenBank Numbers suggests that it has distinct sequences. In a megablast search of the GenBank Numbers database using ITS sequence of I. rubrobrunnea, the closest hit was Inocybe species MCA562 (GenBank Numbers JQ408785; Identities = 616/668 (92%)) followed by Inocybe species AU43 (GenBank Numbers KJ729878; Identities = 605/659 (92%)). An undescribed Inocybe species, Inocybe species AU44 was the closest hit in BLASTn search with LSU (GenBank Numbers KJ729906; Identities = 896/925 (97%)) sequence. Inocybe species AU43 (GenBank Numbers KJ729935; Identities = 670/702 (95%)) resulted as the closest hit in BLASTn search with RPB2 sequences. But, the details of Inocybe species MCA562, an unnamed Inocybe collection from Japan and Inocybe species AU43 and Inocybe species AU44, another unnamed collection from Australia, are not available for comparison.

The RPB2-based ML phylogeny (Fig. 128) placed Inocybe rubrobrunnea in the Pseudosperma clade with full support (100% ML). Within this clade, I. rubrobrunnea clustered with Inocybe species AU43 with a significant support (95% ML).

Marasmiaceae Roze ex Kühner.

The family Marasmiaceae is characterized by white spores. The members of this family mostly have tough stems and the capability of shrivelling up during a dry period and later recovering. According to Kirk et al. (2008), the family contains 54 genera and 1590 species.

Marasmius Fr.

Marasmius is a genus of mushroom-forming fungi in the family Marasmiaceae. It contains about 500 species (Kirk et al. 2008) of which a few, such as Marasmius oreades, are edible. However, most members of this genus are small, unimpressive, brown mushrooms. Their humble appearance contributes to them not being readily noticeable to the layman, and therefore these mushrooms are seldom collected by mushroom hunters. Quite a few of the species are known to grow in the characteristic fairy ring pattern (Fig. 135).

MycoBank number: MB 816959; Facesoffungi number: FoF 2192, Figs. 136, 137

Etymology: referring to the beautiful (luculentus) appearance of the pileus.

Holotype: CUH AM120

Notes: Distinctive features of M. luculentus include a small basidiomes with a convex, plicate, light brown to reddish-grey pileus when young that later turns into white to off-white, with a reddish-brown to brown or dark brown central papilla, collariate and distant to subdistant, often intervenose lamellae (12–14), a small central, insititious stipe arising directly from the substratum, obtuse apical setulae of the pileipellis broom cells and cheilocystidia of the Siccus-type, and moderately-sized basidiospores (10.3 × 4.8 µm; mean Q = 2.2). These combinations of macro- and micro-morphological features easily categorizes the present specimen belonging to sect. Marasmius and subsect. Sicciformes Antonín (Wannathes et al. 2009).

Being a well representative of sect. Marasmius, the new Indian species is morphologically similar to several other species. Marasmius conicopapillatus Henn., described from Cameroon for the first time (Hennings 1895) and later subsequently reported to occur in other African countries (Antonín 2007), Bolivia (Singer 1976), Uganda (Pegler 1977) and Java (Desjardin et al. 2000) differs by its much smaller pileus (1–7 mm diam.) coloured pure white to off-white when young that turns cream-buff at maturity, non-intervenose lamellae, and a considerably larger stipe (12–30 mm long, Desjardin et al. 2000; 22–35 mm long, Pegler 1977) coloured white towards apex. Marasmius pallenticeps Singer, originally described from Argentina, has a much smaller pileus (1–2 mm diam.), a copper brown to reddish-brown coloured stipe that arise directly from the rhizomorphs, and distinctly smaller basidiospores (7–8.5 × 2.7–4.5 µm; Singer 1976). Marasmius chrysochaetes Berk. & M.A. Curtis differs by its much smaller pileus (1.2–2 mm), a longer stipe (22–25 mm long), and differently sized basidiospores (9–10 × 3–3.5 µm, Dennis 1951; 8–9 × 3.5–4.2 µm, Singer 1976). Marasmius stypinoides Petch, described from Hakgala, differs by its much smaller (up to 5 mm diam.) and minutely rugulose pileus, a longitudinally striate and initially white stipe, and a serrate lamellae edge (Petch 1948). Marasmius gracilichorda Corner has smaller basidiomes with a minutely velutinous pileus surface coloured brownish-orange to dark brown overall, yellowish-white lamellae with brownish edges (Tan et al. 2009).

Among other species that grows on bamboo leaves, Marasmius kuthubutheenii Y.S. Tan, Desjardin, Vikineswary & Noorlidah differs by its much smaller (1–3 mm) pileus with a minutely pruinose surface coloured brownish-orange to light brown overall and a very smaller stipe (2–4 mm long; Tan et al. 2009). As revealed in Fig. 136, M. luculentus appears to be phylogenetically close to several other taxa like M. nigrobrunneus (Pat.) Sacc., M. ruforotula Singer, and M. subruforotula Singer. Marasmius nigrobrunneus, originally described from Vietnam and previously reported from India, differs by its smaller pileus (1–4 mm diam.) coloured greyish-black to brown black with slightly paler striae, a long slender stipe (up to 73 mm long), and somewhat differently sized basidiospores (Singer 1976; Manimohan and Leelavathy 1989; Antonín and Buyck 2006; Antonín 2007). Marasmius ruforotula has a greyish-orange to brownish-orange pileus with a black papilla, and yellowish-white lamellae, and presence of numerous black rhizomorphs (Tan et al. 2009). Marasmius subruforotula has a minutely velutinous pileus surface coloured greyish-brown to orange brown often with white striae, discoloured and pale orange coloured lamellae edge, slightly smaller basidiospores with a mean of 9.5 × 4.5 µm (Q mean 2.1), and habitat on dicotyledonous leaves or on wood (Pegler 1977; Antonín 2007; Wannathes et al. 2009).

The new species is macro-morphologically similar to M. capillaris, M. limosus, M. rotalis, and M. rotula, but the latter have cheilocystidia and pileipellis broom cells of the Rotalis-type, and belong in subsect. Marasmius (Petch 1948; Gilliam 1976; Singer 1976; Pegler 1977, 1986; Desjardin 1989; Bas et al. 1995; Corner 1996).

Mycenaceae Overeem

The Mycenaceae is a family of fungi in the order Agaricales which the members are saprobic, have a cosmopolitan distribution, and are found in almost all ecological zones. According to Kirk et al. (2008), the family contains 10 genera and 705 species. This is one of the several families that were separated from the Tricholomataceae as a result of phylogenetic analyses.

Favolaschia (Pat.) Pat.

Favolaschia is a genus of mushrooms in the family Mycenaceae. The genus has a widespread distribution, and contains about 50 species worldwide (Kirk et al. 2008) (Fig. 138).

Basidia 23–26 × 7–8 µm, 4–spored, rarely 2–spored, mostly clavate or constriction in the middle. Gloeocystidia few or none. Hyphae filamentous, hyaline, truly gelatinized, thin walled in parts of the trama, non-gelatinized and often broader and somewhat thick-walled in other parts, predominantly in the pseudostipe, all hyphae inamyloid, and clamp connections present. Gloeocystidia 21–35 × 9–22 µm, mostly clavate or ventricose to subvesiculose, rarely cylindrical, hyaline to yellowish. Dermatocystidia 19–29 × 6–14 µm, hyaline, thin-walled, erect, subvesiculose or broadly ventricose, deep purplish-pink in Cresyl blue mounts, obtuse or rarely somewhat mucronate, crowded at the epicutis, otherwise few.

Notes: This species was first described from Gulf Coast of South America and this is the first report of F. auriscalpium with the molecular phylogenetic confirmation from Sri Lanka. Favolaschia auriscalpium is morphologically closely related to F. calocera R. Heim. but F. calocera differs by having 2 spored, clavate, 38–40 × 7–10 μm size basidia whereas F. auriscalpium has 4 spored, clavate 23–26 × 7–8 µm size basidia. Phylogenetic analysis (Fig. 138) also supports to place the species in F. auriscalpium.

Specimens examined: THAILAND, Chiang Mai Province, Doi Suthep Pui national park, 30 July 2012, Samantha C. Karunarathna (MFLU 12-1892, new record).

GenBank Number ITS:KY649460.

Notes: Cyptotrama asprata was first described from Sri Lanka. It is widely distributed in South and Southeast Asia (Sri Lanka and Laos), East Asia (China, Japan and Korea), New Zealand, Hawaii, and Central America (Martinique and France) (Berkeley 1847; Redhead and Ginns 1980; Yang 1990; Moreau et al. 2015; Qin and Yang 2016). Cyptotrama chrysopepla morphologically resembles to C. asprata because of its’ gold yellow and scruffy appearance, but differs by having smaller squamules, hymeniderm pileipellis, thick walled elements in squamules of stipe, the non-acute subcapitate pleurocystidia and larger basidiospores (8.5–13 × 6.5–10 µm). This is the first report of C. asprata with the molecular phylogenetic confirmation from Thailand.

Boletales E.-J. Gilbert

Boletaceae Chevall.

Boletaceae is a family of mushrooms, first described by the French botanist François Fulgis Chevallier in 1826 as a family distinct from Agaricaceae, primarily characterized by developing their spores in small pores on the underside of the mushroom, instead of gills, as are found in agarics. As a whole, the typical members of the family are commonly known as boletes.

The genus Austroboletus (Corner) Wolfe was established by Wolfe (1979) with the boletoid mushrooms showing the combination of striking morphological features: white to pale cream coloured tube and pore surface which gradually turn pink to pink-rose or sometimes vinaceous on bruising; lacunose to lacerate or reticulate stipe surface; spore print pink to vinaceous or purple brown to rust cinnamon, basidiospores with warted to pitted or reticulate ornamentations; ixotrichodermium or trichodermium nature of pileipellis (Wolfe 1979; Das and Dentinger 2015). According to recent phylogenetic analysis of the members of Boletaceae, this genus is placed under subfamily Austroboletoideae (Wu et al. 2014). About 30 species are reported globally (Kirk et al. 2008) in this genus. Here we describe a new Austroboletus species with the support of morphology and phylogeny (Fig. 146) which was collected from Uttarakhand of India.

Austroboletus appendiculatus Semwal, D. Chakr., K. Das, Indoliya, D. Chakrabarty, S. Adhikari & Karunarathna, sp. nov.

MycoBank number: MB 817672; Facesoffungi number: FoF 2952, Figs. 147, 148 Etymology: referring to stipes (of basidiomata) with appendages.

Holotype: CAL 1304

Diagnosis: is distinct from the closest species A. subvirens by larger and differently coloured pileus, longer and wider stipe, presence of pleurocystidia and caulocystidia and putative association with Shorea sp.

Pileus 75–90 mm. diam.; convex when young, to plano-convex, sometimes uplifted with age; surface areolate-squamose, then disrupted into several patches or segments with the expansion exposing yellowish-orange to greyish-yellow (4B7–4A7, 4B6) subpellis that becoming paler towards margin as pastel yellow to butter yellow, light yellow (3A4–4A5, 4A4); segments of suprapellis light brown to brown, cottony, slightly viscid when wet; margin plane, regular. Pore surface pinkish when young, gradually on bruising or maturity greyish-orange to brownish-orange (5B3–6C3), reddish-grey (12B2), or darker to brown, but paler toward the stipe juncture as light orange grey (6B2), depressed at junction to stipe, unchanging on bruising, pores often up to 2 mm broad at maturity, angular to rectangular, attached. Tubes 12–16 mm long, concolorous to slightly paler then pore surface. Stipe 80–120 × 20–30 mm, central, terete or more or less fusoid towards down, surface distinctly covered with pale orange to light orange (4–5A2–4) or sometimes yolk yellow (4B8) anastomosing broad ridges or appendages forming elevated or flaring to wing-like network (on yellowish-white background) which gradually becoming thin (less elevated) reticulum towards apex, but, never with typical lacerate surface, base with white mycelia elements; ridges cottony, darker with age as golden yellow to brownish-yellow (5B5–6, 5C6). Context white, unchanging, fluffy, partly hollow in stipe. Odour mushroomoid. Taste indistinct. Spore print rust brown to reddish-brown (6E8–8E8). Basidiospores 14.2–14.8–16.5 × 7.3–8–9.1 µm (n = 20, Q = 1.68–1.83–1.97), broadly fusoid to amygdaliform, depressed suprahilar part, surface appears warted by disruption of the outer wall, deeply pitted to form punctuate-warted; under SEM, pits minute at both the fusoid ends, gradually with intricate furrows towards mid region, at mid region with more broader and deeper pits forming warty surface with truncate warts, with disrupted adaxial surface. Basidia 22–32 × 12–16 µm, 4–spored, clavate. Pleurocystidia rare. Tube trama boletoid, gelatinous. Pileipellis trichoderm, composed of erect, septate hyphae; terminal cells cylindrical with rounded apex, width 6–9 µm. Stipitipellis fertile, composed of caulocystidia and caulobasidia. Caulocystidia 40–70 × 11–20 µm, clavate to subclavate, subventricose to appendiculate. Caulobasidia 30–45 × 9–12 µm, 2- to 4-spored, clavate.

Habitat and distribution: Under Shorea robusta Gaertn. in subtropical broadleaf forest.

Material examined: INDIA, Uttarakhand, Dehradun District, Tapovan forest, 650 m, 17 July 2010, K.C. Semwal, KCS 1401 (CAL 1304, holotype; isotype: BSHC).

GenBank Numbers ITS:KX530028.

Notes: Austroboletus appendiculatus is typically featured by combination of characters: brownish areolate-squamose pileus with exposed yellowish subpellis, distinctively reticulate-appendicute and non-lacerate stipe surface, pinkish pore surface that becomes brownish to greyish on bruising or after maturity, partly hollow stipe, almond-shaped deeply pitted basidiospores with distinct suprahilar depression and prominently disrupted adaxial surface and occurrence with putative association of Shorea in subtropical broadleaf forest.

In the field, Austroboletus subvirens (Hongo) Wolfe [≡Porphyrellus subvirens Hongo], A. lacunosus (Kuntze) T.W. May & A.E. Wood [≡A. cookie (Sacc. & Syd.) Wolfe] and A. novae-zelandiae (McNabb) Wolfe [≡Porphyrellus novaezelandiae McNabb] are quite similar (as far as the stipe surface is concerned) to the present taxon. But, A. subvirens (probably the closest species being reported earlier from Japan, Papua New Guinea, China, Americas and Australia and labelled the Australian Material here with GenBank Numbers KP242207, KP242214, KP242212 and KP242210 in Fig. 146) has distinctively smaller (25–60 mm) and differently coloured pileus, shorter and thinner stipe (50–90 × 4–10 mm), and lacks pleuro-, cheilo- and caulocystidia (Wolfe 1979; Jian-Zhe 1985). Moreover, A. subvirens are found to be associated with the trees of Fagaceae in Australasia and Americas and Acacia, Allocasuarina and Eucalyptus in Australia (Wolfe 1979; Horak 1980a, c; Halling et al. 2006) whereas, A. appendiculatus (present species) grows under Shorea robusta (Dipterocarpaceae). Austroboletus novae-zelandiae (reported from New Zealand and New Caledonia and labelled with GenBank Numbers accession number HM060327 in Fig. 146) is separated from the present species by distinctively shorter and slender stipe (70 × 8 mm), bigger (17–19.5 × 8–10.4 µm) basidiospores (Wolfe 1979). Austroboletus lacunosus (reported from Australia and labelled with GenBank Accession Number KC552014 in Fig. 146) can also be separated from the present taxon by smaller pileus (15–25 mm), and stipe (20–50 × 5–6 mm) and smaller (32.5–56 × 10–15.5 µm) caulocystidia (Wolfe 1979).

Only two other species, hitherto known from India: A. olivaceoglutinosus K. Das & Dentinger (labelled with GenBank Numbers KM597478 and KM597479 in Fig. 146) and A. gracilis (Peck) Wolfe can easily be differentiated in the field from the present novel species. A. olivaceoglutinosus which is found in subalpine Himalayan region under Tsuga and Picea has distinguishingly long and slender basidiomata (Pileus 30–55 mm diam., stipe 100–180 × 13–17 mm), highly glutinous olive coloured pileus, lacerate (never with ridges) stipe surface and narrower (12.7–19 × 5.9–7.7 μm) basidiospores showing different ornamentation pattern (Das and Dentinger 2015) whereas, A. gracilis has different pilear surface (subtomentose, velvety or fibrillose), smaller caulocystidia: “14–42(–57) × 4–14 μm” and different pattern (“rugulose punctate”) of spore ornamentation, different host associations (Wolfe 1979; Lakhanpal 1996).

Considering the spore ornamentation, A. fusisporus (reported from Japan and China and labelled with GenBank Numbers AB509830 and JX889719 in Fig. 146) also appears close to A. appendiculatus but the former has altogether different and very small (pileus 5–20 mm, stipe 20–45 × 2–4 mm) basidiomata (Wolfe 1979).

Our ITS phylogeny (Fig. 146) were obtained by the neighbour-joining analysis criterion considering the all available ITS sequences available in GenBank and/or appeared in BLAST search with the sequence of our Indian material. The new sequence forming a separate clade is clustered (80% bootstrap) with the sequences of A. subvirens derived from Australian Material (Fig. 146). These two species in turn is clustered (80% bootstrap) with A. festivus (sequence derived from specimen collected from Guyana).

Unique combination of macro- and micromorphological features coupled with ITS phylogeny clearly support the novelty of Austroboletus appendiculatus.

Boletellus Murrill

Boletellus is a genus of mushrooms in the family Boletaceae (Binder and Hibbett 2006). The genus was first introduced by American mycologist William Alphonso Murrill in 1909 (Murrill 1909). The genus contains about 50 species, has a widespread distribution, especially in subtropical regions (Kirk et al. 2008) (Fig. 149).

Boletellus emodensis (Berk.) Singer, Annales Mycologici 40: 19 (1942)

Facesoffungi number: FoF 3141, Figs. 150, 151

Basidiomata (small to medium-sized. Pileus 3–9 cm in diam., convex to applanate; surface smooth and dry, purple to dull red colour, fading to pale brown with age, finely tomentose when young, then peeling or cracking into large squamules; at first margin extended into a fake veil and covering the pores, then radially splitting, appendiculate with fake veil remnants; context 0.5–1.2 cm thick in the pileus center, yellowish, strongly and rapidly turn to blue when bruised or injured. Hymenophore poroid, yellowish, strongly and rapidly turn to blue when bruised or injured; pores 0.1–0.2 cm diam., simple and angular.

Tube trama made up of thin-walled, colourless to yellowish hyphae 5–13 μm in width. Cheilocystidia 46–69 × 10–18 μm, thin-walled, subfusiform to fusiform, colourless or yellowish-brown in KOH. Pleurocystidia 68–92 × 10–20 μm, subfusiform to fusiform, colourless to yellowish-brown in KOH. Pileipellis is an intricate trichoderm composed of interwoven, thin-walled, yellowish-brown hyphae; terminal cells 18–36 × 6–12 μm, with round to obtuse apex. Pileal trama composed of thin walled, colourless to yellowish hyphae 4–16 μm diam. Clamps absent.

Habit and habitat: Solitary or gregarious on soil, tree stumps or rotten wood in forests dominated by Fagaceae

This is the first report of B. emodensis with the molecular phylogenetic confirmation (Fig. 149) from Sri Lanka.

Rubroboletus Kuan Zhao & Zhu L. Yang

The genus Rubroboletus (Zhao et al. 2014), typified by R. sinicus (W.F. Chiu) Kuan Zhao et Zhu L. Yang, was established to accommodate Boletaceae with reddish pileal surface, an orange, orange-red to blood red surface of the hymenophore, yellow tubes, pink to red net or spots on the stipe, a bluish colour-change when injured, a non-amyloid context (even if the original diagnosis says “not observed”), smooth spores, olive-brown in deposit, and an interwoven trichodermal pileipellis (Fig. 152).

Etymology: the specific epithet of the name of the taxon comes from the Latin word “demonensis” and refers to the ancient name “Valdemone”, which was one of the three valleys (“valli”) or real domains (“reali dominii”) in which the region Sicily was subdivided from the Muslim domination to the Bourbon period; the “Valdemone”, with respect to the “Val di Noto” and the “Val di Mazzara”, constitutes the north-eastern part of the Sicily, an area that closely corresponds to the actual habitat of R. demonensis. Furthermore, the epithet “demonensis” well reminds the peculiar features of the species, i.e. the flaming red colour of the cap and the pores, features shared with other close “devilish” species, belonging to the same genus (R. satanas). Moreover, unforeseeable circumstances would have wanted that one of the first growth stations of R. demonensis had been the locality “Pizzo Inferno” (i.e.: Hell Peak) on the Nebrodi chain, in the common of Floresta.

Holotype: MCVE 29081 (GS10244)

Pileus 60–150(–240) mm broad, initially hemispherical, then convex, pulvinate, in the end almost applanate in mature basidiomes. Margin ± regular in young, soon uneven, ±undulate-lobate, sometimes distinctly lobate in mature specimens. Colour at the very beginning whitish, pale grey, pale ochre (4/A1–B2), soon, starting from the margin, dirty pale pink-lilac (5–12/A1–B2), then strongly variable from light grey (5–7/B1–C2), to pink-lilac (7–12/B2–C3), to purple-red (10–12/B3–C6, 11–12/C6–D8) depending on environmental conditions; with wet weather or in shady woods, the pileus shows particularly bright colours, tending to purple-blood red, quite uniformly distributed on the pileus surface (11–12/C8–D8). In some occurrences, red colour seems not to develop completely both in pores and stipe, and in meantime also the pileus colour stabilizes on a pink-lilac uniform colour (8–11/A3–B4), that becomes blood red when bruised. Conversely, in dry weather or in areas exposed to the sun, pileus colour is much more variable, with flesh pink colours sometimes fading to brownish-grey or to paler tone tending to cream-whitish (7–9/B2–D3). However, in the most of the basidiomes observed, large intensely reddish areas or wide blood red spots persist, even more intense following to scrubbing, touching or other manipulation. Surface typically tomentose and dry at the beginning, sometimes smooth and viscous in wet weather; the cuticle is not detachable from the underlying flesh. Often, in mature large basidiomes, the pileus appears pleasantly bright shining red, darker when bruised. Looking closely at the pileus surface, also with the aid of a lens, minute, in relief, concolorous scales can be noticed. This feature is shared with the close species R. rubrosanguineus, R. legaliae, R. pulcherrimus and R. sinicus. Stipe 80–120(–150) × 40–80(–90) mm, bulky, robust and wide, cylindrical, often gradually enlarged or clavate towards the base, sometimes also obese, not rooting. Surface in rare case yellow orange at the very beginning (4–6/A4–A6), with purplish base (9–10/A4–B6), then, passing through intermediate orange-red tones (7–8/A4–B6), in the end bright red, blood red, purple red, often darker at the base (9–10B7–D8, 9–11D6–D8), often with an evident deep yellow, or orange-yellow band (5–15 mm wide) in the upper part. In some xanthoid aspects stipe does not develop red tones in the upper half, remaining yellow or orange yellow, but the stipe base is anyway red, purple-red, blood red. Bitten areas often show the deep yellow flesh colour, giving a chromatic effect reminiscent of R. rhodoxanthus. A sharp net, with regular meshes, is well distributed over at least ¾ of the height, darker than the colour of the ground; the meshes are usually larger and the ribs usually thicker than those of B. rubrosanguineus or B. legaliae, giving to the net a general rougher appearance with respect to the ones of the close species. The extreme base of the stipe is covered with a whitish grainy, furfuraceous over layer, particularly evident in basidiomes collected on moist grounds. Tubes 5–12(–20) mm, having average length, free at the stipe, from deep yellow to olive green, discolouring blue when cut. Pores small, round, usually from the beginning purple-red, dark red (10–11/C7–D8, 11–12/D7–F8), dull blue when touched, in aged basidiomes orange-yellow towards the margin of the pileus. In some collections, young specimens have yellow pores, that with age develop only an orange, red–orange colour, reminiscent that one of typical R. legaliae. Flesh firm, yellow, deep yellow, lemon yellow (3/A4–A8), particularly intensive in both stipe and pileus wounds; when exposed, quickly turning sky-blue, blue, deep blue (21–23/A4–B6), due to discolouring not particularly intensive, sometimes weak, then fading to a pale grey-cream colour. In some cases, in the exposed pileus or mostly in the lower part of the stipe some beetroot shades may appear. Sub-hymenophoral layer concolorous. Taste sweetish, slightly acidic. Smell weak, fungal and pleasant. Spore print tobacco-brown. Amyloid reaction in the flesh at the stipe base, according to Imler’s procedure (Imler 1950): the tissues at the stipe base are not amyloid in all the collections if examined microscopically. As in R. legaliae and R. rubrosanguineus, sometimes the amyloid reaction could be macroscopically “positive” (Cheype 1983) due to the absorption of the Melzer’s regent in the tissues. Basidiospores smooth, fusiform ellipsoid, with a more or less pronounced suprahilar depression, (12.5–)12.6–13.6(–13.9) × (4.6–)4.7–5.1(–5.1) µm (363/7/7), on average 13.1 ± 0.5 × 4.9 ± 0.2 µm, Q = (2.53–)2.57–2.79(–2.89), Qm = 2.68 ± 0.11, from light yellow to yellow–brownish in KOH. They may have different shape in different collections, despite the molecular investigation has confirmed them as belonging to the same species. In some collections, they are ellipsoid (Fig. 156b), more elongate with respect to those of R. legaliae, smaller both in width and in length with respect to those of R. rubrosanguineus but with almost the same Q ratio; in other collections, they are more fusiform, with the apex opposed to apiculum more tapered and acuminate (Fig. 156c). In some collections, lots of irregular spores, with various, irregular protuberances, may also occur (Fig. 156c(right)). Basidia mostly 4-spored, hyaline, (23.8–)31.3–47.7(–62.6) × (4.2–)7.7–12.7(–13) µm (34/2/2). Facial cystidia fusiform, versiform, sometimes lageniform, hyaline, (15.5–)29.5–44.7(–50.7) × (4.2–)5.3–7.7(–9.5) (64/2/2). Marginal cystidia similar to facial cystidia but smaller, mostly versiform than fusiform or lageniform, hyaline (15.8–)20–29 (37.2) × (3.5–)4.3–6.3(–7.9) (46/2/2). Pileipellis an entangled trichodermium, tending to a cutis, often gelatinized in mature individuals, consisting of thin, cylindrical elements, collapsing gradually during development of the basidiomes. Terminal elements (33.3–)32.9–42.9(–44.3) × (5–)5.2–5.9(–6.9) µm (138/5/5), Q = (6.6–)6.4–8.1, Qm = 7.3, with rounded or tapered tip, sometimes clavate, rarely capitulate or pear-shaped, with pale yellow vacuolar pigment and incrusted pigmented here and there, mostly in the deeper and closer to hypoderma hyphae. Hymenophoral trama boletoid in the sense of Singer (1965, 1967). Clamp connections absent.

Habitat: Rubroboletus demonensis is typical in acid and silicic soils, thermophilic, in summer. It grows in groups of small basidiomes in warm deciduous forests, in mountains or in some cases in mixed deciduous and coniferous woods (Pinus nigra and Taxus baccata), never with pure conifers. It prefers mesic forests of deciduous oaks (Quercus pubescens sensu lato, Q. cerris, Q. congesta and Q. virgiliana), rarely with holm (Q. ilex). It is common in chestnut woods (Castanea sativa), pure or mixed, and at higher elevations with beech (Fagus sylvatica). It is usually collected in June after the late spring rains and, not liking the summer drought, it disappears during the hottest period of July and August, then appears again in September. During the warmer autumns, it can be observed until the first half of October.

Distribution: R. demonensis was found in a rather delimited areal of the South Italy [(Sila Plateau (“Altopiano della Sila”) in Calabria] and Sicily, where it inhabits the mesomediterranean and supramediterranean zone of the mountain strip, characterized by a humid Mediterranean climate, with large rainfalls and Mediterranean humid forest well represented by deciduous forests of oak (Q. pubescens s.l.) and chestnut (C. sativa), some rare patches of evergreen forest with Q. ilex, with the presence of Pinus nigra ssp. calabrica, in an altitudinal range between 1200 m and 1600 m a.s.l.. Sicily seems to be the southern limit of distribution of the species. A unique collection from Greece (04.08.2014, near Nimea Village, Komotini, Rhodope Regional Unit, coord. 4112′42.2″N, 2531′16.5″E, alt. 650 m a.s.l., leg. D. Tragkos) with Q. petraea ssp. medwediewii, proved only by photographic material, represents the most eastern collection. The findings in Spain under Q. faginea and Q. ilex, until now attributed to Imperator rhodopurpureus var. polypurpureus (Ruiz Fernandez & Ruiz Pastor 2006) or R. rubrosanguineus (Calzada Dominguez 2007), seem likely referable to R. demonensis, and, if confirmed, might represent the western (Zamora, Salamanca) and northern (Navarra, Palencia, Huelva) limits of the distribution of the species. The main collection sites in Sicily are the north-eastern mountain range (Appennino Siciliano), the Nebrodi chain and the Madonie chains, but it has also been reported on the Etna volcano massif, where it grows even at higher altitudes. The most of the collections from Sicily comes from the commons of Cesarò, Floresta, Maniace and Troina in the Nebrodi Mountains Park, in the province of Messina.

Edibility: like other closely related species in this genus, it is probably poisonous if consumed raw.

GenBank Number ITS:KY677920.

Notes: During mycological surveys and mapping of Northeast of Sicily, in the territory between mountain ranges of Nebrodi, Peloritani and Madonie and the massif of Mount Etna, several collections of a Boletaceae apparently close to Rubroboletus rubrosanguineus (Cheype) Kuan Zhao & Zhu L. Yang of Northern Italy were observed. They grew exclusively with broadleaved trees and in the first instance they were included in the large colour variability of R. legaliae (Pilát & Dermek) Della Maggiora & Trassin. In the meantime, other sporadic finds of the same bolete occurred in the region Calabria, in the areas of Gambarie and Sila Piccola (Vasquez 2014). However, since the first findings, it was observed that these collections differ from these two neighbouring taxa in chorological-ecological, anatomical and macroscopic characters. The sharp delineation of the new species has become clear in additional collections (Vasquez 2012, 2013), to which some microscopic and molecular differences from the other close, but different species have been later added. Based on the BLASTn results (sequences were selected based on the greatest similarity) and the recent phylogenetic study focused on Rubroboletus (Zhao et al. 2014), sequences were retrieved from GenBank number and UNITE (http://unite.ut.ee/) databases for the comparative phylogenetic analysis with the newly generated sequences. Caloboletus calopus (HM347645) was chosen as an outgroup species. Phylogenetic analyses were performed using the Bayesian Inference (BI) (MrBayes v. 3.2.2, Ronquist et al. 2012) and maximum likelihood (ML) (RAxML v. 7.0.4, Stamatakis 2006; RAxML version 8, Stamatakis 2014) approaches. The ITS data set comprised 52 taxa (24 from GenBank number and 14 from UNITE). BI and ML trees were congruent and only the Bayesian tree with both BYPP (Bayesian Posterior Probabilities) and MLB (Maximum Likelihood Bootstrap) values is shown in Fig. 152. In the analysis, the six sequences of R. demonensis form a highly-supported clade (BYPP = 1, MLB = 100); it resulted as a distinct species, sister (with low support, BYPP = 89, MLB = 54) to R. eastwoodiae. Distinctive features of R. demonensis are the overall purple blood red colour (general appearance close to R. rubrosanguineus with brighter colours), combined with frequent orange-yellow collar in the upper part of the stipe, growth with broadleaved trees (Quercus, Castanea, Fagus) and spores narrower than in the closer species, with a higher Q ratio (13.1 ± 0.5 × 4.9 ± 0.2 µm, Qm = 2.68 ± 0.11). As in the most of the boletes, red colours can be in some situations attenuate: this originates xanthoid aspect, whose appearance is quite close to R. legaliae. R. legaliae has a paler, whitish, greyish-cream pileus tending to pink or reddish [R. legaliae f. spinarii (Hlaváček) Mikšík], more velutinous, and shares in many occurrences in Sicily the same environment of R. demonensis. It has also shorter but stouter in average spores (12.5 ± 0.4 × 5.5 ± 0.1 µm, Q = 2.29 ± 0.05) (533/13/13) and generally paler yellowish-orange pores, even if some bright red pores form do exist. It grows with broadleaved trees, mainly with oaks, in neutral-acidocline or basicline soils (Lannoy and Estades 2001; Estades and Lannoy 2004; Muñoz 2005; Andersson 2013; Halama 2016). It is nevertheless much more widely distributed in Europe and its areal extends North to Denmark, East to Penza region (Russia), South to Sicily (Italy) and West to Baixo Alentejo (Portugal), including: Austria, Bulgaria, Corse, Croatia, Czech Republic, Denmark, France, Germany, Great Britain, Hungary, Ireland, Italy, Montenegro, Norway, Portugal, Romania, Russia, Sardinia, Serbia, Sicily, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey (Courtecuisse and Duhem 2011; Halama 2016). Its occurrence in Russia, until now has been overlooked (Courtecuisse and Duhem 2011; Halama 2016), but this species is known in Russia as rather rare but typical for the middle and southern oakeries, associated with Quercus robur in regions of Penza, Tula (Svetasheva 2010), Volgograd, Stavropol, Lipetsk (Sarycheva and Svetasheva 2015). R. rubrosanguineus is a rare bolete growing in submontane and mountainous regions, on alkaline soil, in spruce and firs (Abies, Picea) woods, also mixed with beech (Fagus), rarely in pure Fagus woods and if so in the areas formerly populated by Abies; it has pileus colour more purplish than R. demonensis, without so intensive and bright red tones (Walty 1969; Cheype 1983; Lannoy and Estades 2001; Estades and Lannoy 2004; Muñoz 2005). It is widespread along the Alpine arch but its distribution western limit is constituted by Spain (Palazon 2006) and reaches the most northern distribution in the West Carpathians (Beskydy Mountains, Czech Republic), even if a doubtful record could set this limit to Belgium (Noordeloos 2010); at East, it extends to Russian Caucasus (Kiyashko 2012; Svetasheva and Kovalenko 2013). The southern limit seems to be constituted by the Italian Appennini chain, in Emilia-Romagna region, where it grows with Fagus in the areas earlier populated by Abies alba. So, its distribution includes Austria, Belgium, Bosnia and Hercegovina, Bulgaria, Croatia, Czech Republic, France, Germany, Greece, Italy, Monte Negro, Poland, western part of Russia, Slovakia, Slovenia, Spain, Switzerland (Courtecuisse and Duhem 2011). R. rubrosanguineus presents spores as slender as those of R. demonensis, but longer and broader (14 ± 0.8 × 5.4 ± 0.3 µm, Qm = 2.58 ± 0.12, (618/20/20).

From both R. rubrosanguineus and R. legaliae, R. demonensis can be distinguished by the net (reticulum) with larger meshes and thicker ribs. R. rubrosanguineus has also significantly broader pileipellis terminal elements (47.7 ± 4.9 × 7.5 ± 0.5 µm, Qm = 6.73 ± 0.49 (42/4/4)) with respect to the other two boletes (37.9 ± 5 × 5.5 ± 0.4 µm, Qm = 7.24 ± 0.89 (138/5/5) and 32.8 ± 0.1 × 5.7 ± 0., 5 µm Qm = 6.15 ± 0.51 (49/2/2) respectively for R. demonensis and R. legaliae). R. pulcherrimus (Thiers & Halling) D. Arora, N. Siegel & J.L. Frank is a North-American species apparently very similar, growing in in the North Western mixed forests of the Coastal Chain (Arora et al. 1999; Desjardin et al. 2015); it has much larger spores (14.3 ± 1.1 × 5.8 ± 0.1 µm, Q = 2.48 ± 0.15 (106/4/4) (Arora et al. 1999).

The phylogenetically closest related Boletus eastwoodiae (Murrill) Sacc. & Trotter differs in the pale greyish pileus, becoming olive-buff-grey and developing pink tones especially along the margin. The stipe is massive, abruptly bulbous with a ventricose base, with pinkish-grey colour and a concolorous or vinaceous reticulation (Bessette et al. 2000; Desjardin et al. 2015). Due to the molecular evidence offered in our work, Suillellus eastwoodiae Murrill is here combined in the genus Rubroboletus.

Rubroboletus eastwoodiae (Murrill) Vasquez, Simonini, Svetasheva, Mikšík & Vizzini, comb. nov.

Index Fungorum number: IF552780; Facesoffungi number: FoF 2813, Fig. 155

Basionym: Suillellus eastwoodiae Murrill, N. Amer. Fl. (New York) 9 (3): 152 (1910)

It is worth noting that the combination R. eastwoodiae (Murrill) Arora, C.F. Schwarz & J.L. Frank (Frank 2015) is invalid (wrong citation of the basionym). Curiously, R. demonensis shares both the growth area and edaphic-environmental conditions of another Mediterranean species very common in Sicily and Calabria, Boletus flavosanguineus Lavorato & Simonini: frequently these boletes are observed growing together (pers. obs.).

The analysis of the spore size distribution with the method of the “isoprobability ellipses” (Simonini 1992, 1998; Consiglio and Simonini 2005) (Fig. 155) is based on average values of 20 collections of R. rubrosanguineus, 13 collections of R. legaliae, and 7 collections of R. demonensis. This comparison allows to analyse better the differences of the spores both in size and shape. It could be observed that spores of R. demonensis and R. legaliae are clearly separated each other even at confidence level of 95%, having R. demonensis clearly shorter and narrower spores. R. rubrosanguineus has some overlapping with the other species only at confidence level of 95%, while at 68% there is almost no overlapping: R. demonensis has narrower and stouter spores with respect to R. rubrosanguineus, and the latter has slender and longer spores with respect to R. legaliae. The difference in width of the spores of R. rubrosanguineus and R. legaliae is statistically not significant.

Strobilomyces Berk.,

The genus Strobilomyces Berk. is a member of the family Boletaceae and characterized by greyish or blackish basidiomata; presence of fibrillose squamules or scales on pilear surface; stipe dry, woolly to shaggy, with or without annulus; ornamented basidiospores (Bessette et al. 2010; Das et al. 2014). This genus includes nearly 40 taxa (Gelardi et al. 2012; Wu et al. 2014; Antonín et al. 2015) around the globe. During a macrofungal survey to East District of Sikkim (a small Himalayan state in India), an interesting member this genus was collected and here it is described as a novel taxon (S. longistipitatus) with its morphology and phylogeny (Fig. 157).

Holotype: CAL 1336

Diagnosis: Distinct from the European species Strobilomyces strobilaceous by its exceptionally long stipe, significantly short tubes and frequent occurrence of tongue-like appendages on the wall of the ridges of basidiospores. Pileus 37–50 mm. diam.; convex when young, becoming pyramidal to convex with maturity; surface densely squamulose to floccose in numerous conical clusters of somewhat repent pattern, greyish-brown to violet brown (11E3–11F4) to blackish, reddish with KOH; margin wavy with sterile flap of tissue, brownish-black.

Stipe 110–200 × 17–28 mm, central, dark grey to (11F4) or black; surface cotton like or floccose with white basal mycelium. Context solid in pileus and stipe; context in pileus and stipe chalky white but immediately turning pastel red (8A4) and then greyish-red (8C5) or darker on exposure, turning orange (6A7) with KOH, greyish-green (25E5) with FeSO₄, greyish-green (25D4) with guiacol. Spore print blackish-brown. Odour like Boletus edulis. Basidiospores 10–11.1–12.7 × 8–9.1–9.9 µm (n = 20, Q = 1.16–1.22–1.33), broadly ellipsoid to ellipsoid, ornamentation composed of high ridges forming complete reticulum; under SEM with broad and confluent ridges (of irregularly wavy walls) forming complete reticulations and with frequent tongue like erect appendages on the wall of ridges, blackish-brown.

GenBank Numbers ITS:KX364694.

Notes: Characteristic features of S. longistipitatus are presence of short pileus with almost blackish dense squamules on surface in numerous conical clusters arranged repently (never erect), exceptionally long stipe (3–4 times or more of pileus diameter) without any striation or reticulation on the surface, distinguishingly short white sinuate tubes which becomes reddish-orange on bruising, basidiospores with complete reticulum with the confluent ridges and frequent occurrence of tongue-like appendages on the ridge-walls and occurrence in association with the coniferous trees.

Our ITS based phylogeny (Fig. 156) clearly supports the existence of two distinct and strongly supported clades (Clade A and Clade B) in Strobilomyces which are also reported repeatedly by earlier workers (Gelardi et al. 2012; Antonín et al. 2015) however, another clade represented by the only species S. annulatus Corner from Malaysia (sequence of ITS region is not yet available in GenBank) is also known when phylogeny is conducted based on partial sequences of the largest subunit of RNA polymerase II (RPB2) as shown by Gelardi et al. (2012) and Antonín et al. (2015). Here, Clade A includes S. confusus Singer, S. seminudus Hongo, S. verruculosus Hirot. Sato where basidiospores are never reticulated as also stated by Gelardi et al. (2012) and Antonín et al. (2015). Distinguishingly, Clade B represents S. strobilaceous (Scop.: Fr) Berk., S. appendiculatus sp. nov., S. echinocephalus Gelardi & Vizzini., S. pteroreticulosporus Antonín & Vizzini, S. mirandus Corner where basidiospores are typically reticulate (Gelardi et al. 2012, Antonín et al. 2015). Basidiospore-ornamentation pattern is known to be the reliable parameter in the delimitation of major groups of Strobilomyces. Recently, on the basis of morphology and ITS data Petersen et al. (2012) showed the existence of only a single species of Strobilomyces in Europe, as S. strobilaceus. Therefore, we considered (Fig. 156) only the sequences derived from European collections as S. strobilaceus sensu stricto in our phylogeny. Our LSU based phylogeny which was conducted considering all the Strobilomyces LSU sequences appeared on BLAST (or available in GenBank) search with our specimen (GenBank Numbers KF112459, KF112460, KF112463, KF030345, DQ534626) and some other species of Boletaceae also clearly supports the position of the present specimen amongst Strobilomyces and confirms the novelty (Fig. 157). Here three sequences labelled as Strobilomyces sp. (Wu et al. 2014) are placed in the weakly supported sister clade of present species (94–95% identity with S. longistipitatus for 91% query coverage using BLAST).

Morphologically, this Indian specimen is quite similar to S. strobilaceous (an European species represented here by GenBank Numbers JQ319001, JQ318998, JQ318984, JQ318975, JQ318977 and JQ318988 in Fig. 156) and S. echinocephalus (reported from China) but, the former (probably the closest relatives of present species) differs from S. longistipitatus by its considerably shorter stipe [60–140 mm and 80–150 mm as mentioned by Breitenbach and Kränzlin (1991) and Knudsen and Vesterholt (2012) respectively] and longer tubes (10–15 mm) whereas, the latter is distinct from the present Indian specimen by its much shorter stipe (74–105 mm), presence of striation on stipe apex and longer tube (9 mm). Phylogenetically, both the species are well distinct as shown in Fig. 156. Three more species: S. alpinus, S. pteroreticulosporus, S. mirandus are also partly close to S. longistipitatus. Strobilomyces alpinus can be separated in field by the presence of longitudinal striations on stipe and unchanging exposed context and larger spores (12.5–15 µm) (Gelardi et al. 2012). Strobilomyces pteroreticulosporus is distant by its pileus surface which is covered with pyramidal fibrillose dirty whitish scales, longer (30 mm) tubes and shorter (100–140 mm) stipe (Antonín et al. 2015) whereas, S. mirandus has yellow or golden orange to brownish-orange pileus, longer (up to 10 mm) tubes and distinctly smaller (40–70 mm) stipe (Sato et al. 2005).

Strobilomyces polypyramis Hook. f., another species recently reported from the state Sikkim can easily be separated by presence of erect, small conical to pyramidal, pointed or rarely spinoid black scales, longer tube (up to 13 mm), shorter stipe (80 mm), absence of complete reticulum in basidiospores (Horak 1980a, c; Das et al. 2014). Strobilomyces dryophilus Cibula & N.S. Weber (96% identity with S. longistipitatus for 95% query coverage using BLAST) and S. floccopus were also appeared close (though well separated) in the LSU phylogeny along with our Indian material (Fig. 157). But, S. dryophilus is morphologically distinct from S. longistipitatus by its whitish ground coloured pileus with coarse, woolly appressed or erect, greyish-pink or pinkish-brown scales, 10–17 mm long tubes, and much shorter (40–80 mm) stipe (Bessette et al. 2010). Whereas, S. floccopus (sequence derived from European material) is considered as the synonym (Petersen et al. 2012; Gelardi et al. 2012) of S. strobilaceous (morphological comparison given in the earlier paragraph).

According to unique combination of morphological data and phylogenetic analyses of ITS and LSU sequences, our specimen from India should be treated as an independent species, proposed as S. longistipitatus which is placed in Clade B (Fig. 156) along with other species featured with reticulate basidiospores.

Cantharellales Gäum.

Clavulinaceae Donk

Clavulinaceae was described in 1970 by Donk to accommodate the genus Clavulina, based on bisterigmate, secondarily septate, and stichic basidia. Currently, it includes four genera and belongs to Cantharellales (Kirk et al. 2008). It is characterized by having simple, branched or resupinate basidiomata, monomitic hyphal system, clamped or not hyphae, and cystidia that is present in a few species. The basidia are clavate or subcylindric, with sterigmata generally incurved and the basidiospores are usually globose, subglobose to ellipsoid, smooth, guttulate and inamyloid. They are reported as saprobes, ectomycorrhizal and lichenized (Corner 1950; Donk 1964; Moncalvo et al. 2006; Bernicchia and Gorjón 2010).

Clavulina J. Schröt.

Clavulina J. Schröt. accommodates species usually with branched basidiomata, occasionally simple, infundibuliform, effused-coralloid or resupinate, typically with two smooth, hyaline, guttulate basidiospores per basidia, and cornute sterigmata. Additionally, a septum is sometimes formed at the base of the basidia after the release of basidiospores (Corner 1950, 1970; Petersen 1988; Thacker and Henkel 2004; Henkel et al. 2005; Uehling et al. 2012a). Clavulina is a genus of ectomycorrhizal fungi with about 75 species widely distributed mainly in tropical regions (Uehling et al. 2012b). Studies about the phylogeny of the genus show its monophyly within Cantharellales (Thacker and Henkel 2004; Moncalvo et al. 2006; Olariaga et al. 2009; Uehling et al. 2012a, b).

GenBank Numbers URM 89967 ITS:KX811199, URM 89968 ITS:KX811184.

Notes: This species is characterized by the slender, flexible, fleshy and greyish basidiomata when fresh, brittle when dry, and by the hymenial, hyaline cystidia with homogeneous to granular contents. Clavulina grisea composed of several solitary basidiomata growing on soil covered by rotten leaves and branches.

Other species of Clavulina with greyish basidiomata and cystidia have been reported by Corner et al. (1956), Corner (1970) and Petersen (1983). Clavulina hispidulosa Corner, however, has subhyaline to pale yellow or pale brownish, subglobose to obovoid, larger basidiospores (8–12 × 7–10.5 μm), while C. griseopurpurascens Corner has hyaline, usually ellipsoid basidiospores (7.5–8.7 × 6–7 μm).

The specimens of C. grisea are grouped in a well-supported clade (100% ML/100% MP/1.00BYPP) sister of C. cristata (80% ML) (Fig. 160). Clavulina cristata (Holmsk.) J. Schröt. is characterized by white, often becoming yellowish, ochraceous or fuliginous basidiomata, branches with acute tips usually becoming cristate, and larger, slightly thick-walled basidiospores (7–11 × 6.5–10 μm).

Another greyish species in the phylogenetic analyses (Fig. 160) are C. cinerea (Bull.) J. Schröt., C. craterelloides Thacker & T.W. Henkel and C. griseohumicola T.W. Henkel, Meszaros & Aime, all without cystidia. Additionally, C. cinerea has yellow or ochraceous, subglobose or broadly ellipsoid, basidiospores (6.5–11 × 6–10 μm); C. craterelloides has infundibuliform basidiomata, and hyaline, subglobose to broadly ellipsoid, basidiospores (6.5) 7.5–8 × (5.5) 6–7 (7.5) μm; and C. griseohumicola has dark bluish-grey, simple basidiomata, and subglobose basidiospores (8–9.5 × 7–9 μm) (Fig. 161).

Clavulina ossea Meiras-Ottoni & Gibertoni, sp. nov.

MycoBank number: MB 818103; Facesoffungi number: FoF 2956; Figs. 162

Etymology: ossea (Latin) = bone, referring to appearance basidiomata after drying.

Holotype: URM 89970

Basidiomata branched, solitary or in small groups, with fleshy consistency, –10 cm, polychotomous branches, the tips of branches are unique or rarely cristate, becoming dark, stem visible, sterile, when fresh dark brown (8F6), branches brownish-lilac grey (10C2, 16B2), hymenium amphigenous starting just below the branch point and extending to the apex of the branches. Basidiospores globose to subglobose, 6–9 (L = 7.66) × 5–7.5 (W = 6.56) μm, Q = 1.14, smooth, hyaline, with one large oleiferous guttule, thin-walled, with short apiculus (0.2–1 μm), IKI-. Hyphal system monomitic, tramal hyphae smooth sometimes verrucous, parallel, hyaline, 3–10 μm, some hyphae are wide but not inflated, clamp connections abundant, subhymenium tightly interwoven. Cystidia absent. Basidia cylindrical, 21–44 × 5–6 μm, hyaline, multi-guttulate, with 2 cornute sterigmata, 4–5 μm, postpartal septa observed on most basidia.

Material examined: BRAZIL, Paraíba: Areia, Parque Estadual Mata do Pau-Ferro, June 2015, C.O. Mendonça (URM 89970, holotype; isotype in O).

GenBank Number ITS:KX811197.

Notes: This species is characterized by the robust, fleshy, and pale lilac basidiomata when fresh, resembling bones when dry, and hyphae occasionally incrusted. The new species is composed of several solitary or in pairs basidiomata, scattered on soil covered by rotten leaves and branches. Of the species of Clavulina with similar colour (vinaceous, lilac or purple tints), C. incrustata can be distinguished by the basidiomata with very rare clamp connections and ferruginous brown, incrusted hyphae (Wartchow 2012); C. amethystina (Bull.) Donk by the ovoid-ellipsoid or subglobose, slightly larger basidiospores (7–11(–12) × 6–8 μm), while C. amethystinoides (Peck) Corner by the subglobose to broadly ellipsoid (7–10 × 6–8 μm). In all phylogenetic analyses, C. ossea comes an isolated position within the genus (Fig. 160).

Clavulina paraincrustata Meiras-Ottoni & Gibertoni, sp. nov.

MycoBank number: MB 818102; Facesoffungi number: FoF 2957, Figs. 163

Etymology: paraincrustata (Greek + Latin) = similar to Clavulina incrustata, referring to the extracellular incrustations on the hyphae of the context.

Holotype: URM 89969

Basidiomata branched in caespitose clusters, more rarely solitary or in pairs, somewhat fused basally, initially monopodial but branching early, with fleshy consistency, −8 cm, branches occasionally hollow, tips of branches cristate, stipe visible, sterile, when fresh brownish-orange (6C7, 6C8), branches violet brown (11F8), hymenium unilateral, appearing initially above first branching point. Basidiospores globose to subglobose, 6–8 (L = 7.49) × 5–7 (W = 6.32) μm, Q = 1.20, smooth, hyaline, with one large oleiferous guttule, thin-walled, with short apiculus(–1 μm), IKI-. Hyphal system monomitic, tramal hyphae frequently incrusted, parallel, very compact, brownish, 2–10 μm, not inflated, without clamp connections. Cystidia absent. Basidia elongate-clavate, 31–48 × 4, 5–7 μm, hyaline or with granular cytoplasmic contents, with 2 cornute sterigmata, rarely 3, 4–5 μm, postpartal septa observed on most basidia.

Specimen examined: BRAZIL, Paraíba: Rio Tinto e Mamanguape, Reserva Biológica Guaribas, May 2015, A. Meiras-Ottoni (URM 89969, holotype; isotype in O).

Additional specimen examined: Brazil, Pernambuco: Igarassu, Refúgio Ecológico Charles Darwin, May 2010, F. Wartchow (URM 82947).

GenBank Numbers ITS:KX811201; LSU:KX811196.

Notes: This species is characterized by the robust and violet brown basidiomata when fresh, brittle when dry, and incrusted hyphae. It is composed of several solitary or in pairs basidiomata, scattered on soil covered by rotten leaves and branches.

Wartchow (2012) described C. incrustata Wartchow, the first species of Clavulina with incrusted hyphae, based in material collected in Brazil. Despite being microscopically similar, it differs from C. paraincrustata by the less robust, paler basidiomata, and the amphigenous hymenium. DNA of the type was tentatively extracted, without success.

Clavulina paraincrustata was grouped (94% ML/94% MP/1.00BYPP) with C. craterelloides and C. rosiramea Uehling, T.W. Henkel & Aime (Fig. 160), from which can be distinguished by the lack of incrusted hyphae. Additionally, C. craterelloides has infundibuliform basidiomata, subglobose to broadly ellipsoid basidiospores [(6.5) 7.5–8 × (5.5) 6–7 (7.5) μm], while C. rosiramea has simple or slightly branched basidiomata, with orange tints, subglobose to slightly triangular [(6.5) 7–9 (10) × (6) 7–8 (9) μm].

Polyporales Gäum.

Fomitopsidaceae Jülich

Fomitopsidaceae is a family of Polyporales and currently comprises 24 genera and 197 species (Kirk et al. 2008), with Fomitopsispinicola (Sw.) P. Karst as the type species. The species are characterized by the basidiomata annual or perennial, resupinate, applanate, effuse or pileate, woody, leathery or corky in texture. The hymenium is poroid, and the hymenial surface is usually pale or brownish. The hyphal system is di- or trimitic and clamp connections are usually present (Cannon and Kirk 2007). Most genera of Fomitopsidaceae such as Antrodia P. Karst. Fomitopsis P. Karst., Daedalea Pers., Laetiporus Murrill are of ecological, evolutionary and economic importance because this group has many forest pathogens and cause brown rot which also play an important role in carbon sequestration (Fukami et al. 2010; Ortiz-Santana et al. 2013; Zhou and Wei 2011).

Fomitopsis P. Karst.

Fomitopsis includes species with basidiomata sessile to effused-reflexed, rarely annual to perennial, varying from white to purple, and di- to trimitichyphal system with clamped generative hyphae. The basidiospores are smooth and hyaline, thin-walled, ranging from subglobose to cylindrical (Gilbertson and Ryvarden 1986; Ryvarden and Gilbertson 1993; Dai 2012). It is a cosmopolitan genus, causing brown rot in the substrates, and several species were used as biological models in genetic analyses, as well as ecological, biotechnological and taxonomic studies (Högberg et al. 1999; Chlebicki et al. 2003; Aime et al. 2007; Watanabe et al. 2010) (Fig. 164).

Fomitopsis flabellata Soares & Gibertoni, sp. nov.

MycoBank number: MB 817408; Facesoffungi number: FoF 2958, Figs. 165

Etymology: flabella (Latin) = The name refers to the fan-shaped basidiomata.

Holotype: URM 89405

Basidiomata annual, biannual, pileate, dimidiate, solitary or in small groups or clusters. Pileus 0.2–2 cm wide, up to 2 cm long, 0.3 mm thick at base, upper surface purple (9.1E purple) when fresh and dried, azonate to zonate, glabrous to slightly velutinate. Margin obtuse, entire. Pore surface pinkish-brown to lilac-violaceous (9.4D pinkish-brown, 11.5E lilac violaceous), pores round to angular (3–4 mm), dissepiment thin and entire. Context purple brownish (9.1F brownish), 0.1 mm thick.

Basidiospores cylindrical to sub-cylindrical, 4–5 (6.5) × 2–2.5 μm, smooth, thin-walled, IKI–. Basidia clavate with four sterigmata, 8–10 (12) × 4–5 μm. Hyphal system trimitic, generative hyphae clamped, thin-walled, 2–3 μm in diam.; skeletal hyphae dominant, thick-walled, hyaline, 3–5 μm in diam.; binding hyphae thick-walled, hyaline, 1.5–2.5 μm in diam. Cystidia absent.

GenBank Numbers ITS:KX423688; LSU:KX423686.

Notes: Fomitopsis flabellate can be recognized by the small, usually fan-shaped, coriaceous, brown-vinaceous basidiomata. Fomitopsis lilacinogilva (Berk.) J.E. Wright & J.R. Deschamps and F. cupreorosea (Berk.) Carranza & Gilbn. have a similar colour, but differ by the larger and thicker basidiomata (2–20 × 2–9 × 0.5 × 10 cm; 5–16.5 × 2.6–10.3 × 0.3–2.5 cm, respectively). Besides, the pores in F. lilacinogilva are slightly labyrinthiform (1–2 mm) and sub-daedaleoid, becoming sinuous-daedaleoid in F. cupreorosea (1–3 mm), while in F. flabellata they are round to angular. Fomitopsis flabellata is placed as a basal taxon of the Rhodofomitopsis sensu stricto, but with low statistical support (Fig. 164). For the time being, we prefer to keep this species in Fomitopsis until new sequences are added to the Antrodia clade phylogeny.

Fomitopsis roseoalba Soares, Ryvarden & Gibertoni, sp. nov.

MycoBank number: MB 812876; Facesoffungi number: FoF 2959, Fig. 166

GenBank Numbers ITS:KT189139; LSU:KT189141.

Notes: This species is easily recognized by the white to pink, pileate to effuse-reflexed basidiomata. Of the neotropical species, F. nivosa (Berk.) Gilbertson and Ryvarden has similar whitish colour and morphology (pileate, and sometimes effused-reflexed), but is separated by having cylindrical basidiospores (6–9 × 2–3 μm) and smaller pores (6–8 mm). Despite herbaria revision and several collections in other parts of the Brazilian Amazonia, F. roseoalba was only found in the Eastern Brazilian Amazonia, what indicates that this species may be restricted to this region. According to our molecular analyses, F. roseoalba grouped into a well-supported clade (81/0.99) with one unidentified, endophytic Fomitopsis isolated from Hevea brasiliensis sapwood collected in Brazil (Fomitopsis sp. NHB31) (Martin et al. 2015). This isolate may represent an endophytic stage of F. roseoalba. The F. roseoalba clade grouped in a major clade (98/1.00) with F. subtropica B.K. Cui, Hai J. Li and M.L. Han and two unidentified, endophytic Fomitopsis isolated from Elaeis guineensis from Thailand (Fomitopsis sp. 9 V 3.1 and Fomitopsis sp. 7R 8.1) (Rungjindamai et al. 2008), all included in the Fomitopsis sensu stricto (75/1.00).When in a resupinate form, F. roseoalba is whitish as F. subtropica, and both have similar basidiospores (cylindrical to oblong-ellipsoid 3–4.7 × 1.7–2.3 μm in F. subtropica). Fomitopsis subtropica, however, has smaller pores (6–9 mm) and the pileus, when present, is white to cream (Li et al. 2013b). Li et al. (2013b) suggested that the two specimens of Fomitopsis sp. from Thailand (7R 8.1, 9 V 3.1) could be F. subtropica, because of the high supporting values uniting them in their study (100/1.00). Although the phylogenetic relationship of these three Fomitopsis species was strongly supported, our analyses indicates that F. subtropica, F. roseoalba and Fomitopsis sp. (7R 8.1, 9 V 3.1) are clustered in an independent way (Fig. 164).

Polyporaceae Fr. ex Corda

Favolus (Fr.) Sotome & T. Hatt.

The genus Favolus, typified by F. brasiliensis (Fr.) Fr, is a wood decaying fungus within the Polyporaceae, Polyporales. Previously, Núñez and Ryvarden (1995) treated Favolus as one of the six infrageneric groups of the genus Polyporus, and recently Sotome et al. (2013) proposed as a new genus based on phylogenetic analyses of LSU and ITS regions and morphological characters such as a radially striate pileus, and lack of distinct cutis of agglutinated hyphae. This genus is well supported by multi-gene phylogenies (Binder et al. 2013; Seelan et al. 2015) (Fig. 167).

Favolus gracilisporus H. Lee, N.K. Kim & Y.W. Lim, sp. nov.

Index Fungorum number: IF552508; Facesoffungi number: FoF 2626, Fig. 168

Etymology: referring to a slenderer spore relative to other Favolus species.

Holotype: SFC20130704–40

Basidiocarps annual, lateral stipitate; pileus circular to flabellate, up to 40 mm in diam., up to 3.5 mm thick; pileal surface ivory to pale buff, with age becoming brown, fibrillose with flattened, radially striate, azonate, slightly glabrous, margin concolorous, acute, lacerate. Hymonophore cream to pale brown when fresh, pores diamond-shaped, radially elongated, 2–3 mm long, 1–2 mm wide near stipe to 2–3 per mm at margin; dissepiments thin and lacerate with age. Context in pileus pale tan to ivory, corky, brittle when dry, up to 0.5 mm thick. Tube continuous with the context, up to 2–3 mm thick. Stipe lateral, buff, glabrous, up to 7 mm long and 6 mm thick. Hyphal system dimitic; generative hyphae hyaline in KOH, thin-walled, 3–4 μm in diam., septa with clamps, skeletal-binding hyphae thick-walled, aseptate, much branched, with tapering apices, 3–6 μm diam. Cystidia absent. Basidia clavate, 4–sterigmate (up to 4.5 μm), 27–35 × 5.7–8 μm, with a basal clamp. Basidiospores cylindric, hyaline, smooth, IKI-, 7.9–9.7 × 2.5–3.3 μm. L = 9 μm, W = 2.9 μm, Q = 3.11 (n = 20/1).

Habitat: solitary to gregarious on dead wood of hardwood.

Material examined: KOREA, Gyeongsangbuk-do, Yecheon-gun, Mt. Hagga, on rotten angiosperm stump, 4 July 2013, Y.W. Lim (SFC20130704–40, holotype).

GenBank Number ITS:KY038472.

Notes: Favolus gracilisporus shares similar characteristics with Favolus brasiliensis (Fr.) Fr., Favolusroseus Lloyd, and Neofavolusalveolaris (DC.) Sotome & T. Hatt. such as lateral stipitate basidiocarps with radially elongated and hexagonal pores; however, F. gracilisporus has distinctly larger basidia (27–35 × 5.7–8 μm) compared to F. roseus (18–23.8 × 4.5–7 μm, Sotome et al. 2013) and N. alveolaris (17.5–26 × 4–7 μm, Sotome et al. 2013). Microscopic features of F. brasiliensis are somewhat similar to F. gracilisporus, but the latter species has a larger basidiospore Q value (3.11) than F. brasiliensis (Q = 2.75, Sotome et al. 2013). Phylogenetic analysis based on the ITS region indicated that F. gracilisporus separated distinctly from the other three species (Fig. 167).

Lentinus Fr.

Lentinus (Fr.) Quel is a cosmopolitan genus with an estimated 63 species (Kirk et al. 2008) and 629 records under the name of Lentinus in the Index Fungorum (2017) and, species are able to survive over a wide temperature range, are abundant in boreal, temperate and tropical regions (Pegler 1983; Corner 1981; Karunarathna et al. 2011) (Fig. 169).

Notes: The wide distribution of Lentinus velutinus complex has resulted in a range of variations and in some instances constant morphological differences limited to restricted geographical areas. This is the first report of L. velutinus with the molecular phylogenetic confirmation from Sri Lanka after Pegler (1983) has previously reported it.

Panus Fr.

The generic delineation and phylogenetic relationships between Lentinus and Panus and their accepted allies Neolentinus, Heliocybe, and Pleurotus has been controversial (Corner 1981; Pegler 1983; Redhead and Ginns 1985; Singer 1975, 1986). Corner (1981) treated Lentinus and Panus as separate genera on the basis of their hyphal system and some species were placed in Pleurotus by Singer (1975), whereas, Pegler (1983) treated Panus as a subgenus of Lentinus and included several species of Singer’s Pleurotus in Panus (Fig. 176).

Material examined: THAILAND, Chiang Rai Province, along the road number 1149, Mae Fah Luang Sub-District, Mae Fah Luang District, 17 June 2014, collector Benjarong Thongbai (MFLU 16-2129, holotype).

GenBank Number ITS:LT614958.

Notes: Panus subfasciatus is characterized by its brownish violet to purple brown young basidomata. Later they turn greyish ruby, leathery, solid, dry and are fully covered with short brownish grey hairs. In some aspects it bears a superficial resemblance to Panus fasciatus (Berk.) Singer and Lentinus concentricus Karunarathna, K.D. Hyde & Zhu L. Yang. Panus subfasciatus is easily distinguished from P. fasciatus with its ochraceous basidiomata and abundance of sclerocystidia, which are clavate or fusoid, 22–32 × 4–9 μm (Corner 1981; Pegler 1983). Panus subfasciatus differs from L. concentricus by the latter having yellowish brown-clay, velvety, concentrically zonate of basidiomata and absence of sclerocystidia (Karunarathna et al. 2011). Panus subfasciatus also bears a superficial resemblance to Panus conchatus (Bull.) Fr. which also has purplish brown basidiomata but is lacking cilia. The phylogenetic trees obtained from RAxML analyses are shown in Fig. 176. Panus subfasciatus was statistically supported in the Polyporaceae. In the major clade, P. subfasciatus clustered in a subclade that predominantly contained Panus species and Lentinus strigosus, while a second subclade exclusively contained Lentinus species. Panus subfasciatus appeared most similar to P. conchatus (unpublished according to the entry in GenBank) and a yet undescribed Panus species (BS = 82%). The phylogenetic tree suggests that the nrITS region may be useful for preliminary phylogenetic analyses, also because this is the most frequent DNA locus from which references are available. However, an expanded taxon sampling, best supported by a multi gene genealogy, should be carried out to redefine the boundaries between Lentinus and Panus. The new fungus was recently referred to as Lentinus cf. fasciatus in a report of a new secondary metabolite named lentinulactam (Helaly et al. 2016). Nevertheless, after the outcome of the phylogenetic study we preferred to place it in the genus Panus because it is appears closer to the type species of that genus, P. conchatus.

Polyporus P. Micheli ex Adans.

Polyporus is a well-known genus of wood rotting fungi, which produce stipitate basidiocarps with dimitic hyphal system that causes white rot (Ryvarden 1991; Ryvarden and Gilvertson 1994; Núñez and Ryvarden 1995; Sotome et al. 2007). Núñez and Ryvarden (1995) divided this genus into six infrageneric groups based on macro-morphological characters and recent phylogenetic analysis showed that Polyporus sensu lato is separated into at least five well-defined clades as follows: Dendropolyporus, Favolus, Neofavolus, Polyporellus, and Polyporus (Sotome et al. 2008; Krüger et al. 2006; Sotome et al. 2013; Binder et al. 2013; Seelan et al. 2015). Morphological characteristics and phylogenetic analysis of six new species from Korea are described below. The phylogenetic tree is presented in Fig. 178.

Polyporus brevibasidiosus H. Lee, N.K. Kim & Y.W. Lim, sp. nov.

Index Fungorum number: IF552513; Facesoffungi number: FoF 2631, Fig. 179

Etymology: referring to the characteristic short basidia.

Holotype: SFC20130808-24

Basidiocarps annual, central stipitate; Pileus circular, plane then funnel-shaped, up to 30 mm diam., 1.5 mm thick; pileal surface light buff in the center, brown near margin, fibrillose with flattened, radially striate, glabrous, margin reddish-black, undulate, enrolled. Hymonophore white, cream to brown; pores fine, rounded to angular, 8–9 per mm. Context in pileus pale buff, corky, up to 1 mm thick. Tube continuous with the context, up to 0.5 mm thick. Stipe central, brown to dark brown, smooth to longitudinally wrinkled, apex distinct from the pore, up to 40 mm long and 2 mm thick. Hyphal system dimitic; generative hyphae hyaline in KOH, thin-walled, 2.5–3 μm in diam., septa with clamps, skeletal-binding hyphae thick-walled, aseptate, much branched, with tapering apices, 3–6 μm diam.

Habitat: solitary to gregarious on dead wood of hardwood.

Material examined: KOREA, Gyeongsangbuk-do, Sangju-si, Mt. Noem, on fallen hardwood branch, 8 August 2013, H. Lee, W. J. Kim & S-Y. Oh (SFC20130808-24, holotype). KOREA, Gangwon-do, Inje-gun, Baekdam temple, on fallen hardwood branch, 9 July 1999, Y. W. Lim (SFC19990709-26, paratype).

GenBank Number ITS:KY038474.

Notes: This species shares similar characteristics with many Polyporus species including eccentric stipe, thin pileus, and small pores. Although the smaller pileus (less than 3 cm), pores (8–9 mm) and basidia (15–16.6 × 6.3–7.4 μm) of P. brevibasidiosus are distinguishable characters, morphology alone is not sufficient for species level identification. ITS sequence analysis is useful to confirm its identity and phylogenetic position.

Notes: This species is often confused with P. melanopus, P. ulleungus and P. varius because of similar basidiocarps and microscopic features; however, the smaller basidiospore of Polyporus koreanus (5.7–6.9 × 2.1–2.3 μm) is distinguishable from P. melanopus (7–9 × 3–3.5 μm), P. ulleungus (6.8–8 × 2.3–3.3 μm) and P. varius (9–12 × 2.5–3 μm) (Gilbertson and Ryvarden 1987).

Notes: This species has variable basidiocarp shapes similar to Polyporus varius. Therefore, many of specimens in Korea had been misidentified as Polyporus varius. Two types of P. varius sequences were reported in a previous study (Sotome et al. 2008). The first included sequences from the USA, Russia, and Japan (Sotome et al. 2011; Dai et al. 2014) and the second was unique to Japan (AB587635, Sotome et al. 2011). Phylogenetic analysis based on ITS sequences showed that P. orientivarius formed a monophyletic group with the second type of P. varius sequence and was distantly related to P. varius (Fig. 3). In addition, P. varius has smaller pores (7–9 mm) and longer basidiospores (9–12 × 2.5–3 μm) (Gilbertson and Ryvarden 1987) than those of P. orientivarius. Therefore, both morphological and molecular evidence support P. orientivarius as a new species that is clearly separate from P. varius.

Polyporus parvovarius H. Lee, N.K. Kim & Y.W. Lim, sp. nov.

Index Fungorum number: IF552511; Facesoffungi number: FoF 2629, Fig. 182

Etymology: referring to the similar but smaller basidiocarps compared to P. varius.

Holotype: SFC20120814-33

Basidiocarps annual, central stipitate; Pileus circular, plane then funnel-shaped, up to 35 mm diam., 1.5 mm thick; pileal surface light buff to brown, fibrillose with flattened, radially striate, glabrous; margin reddish-brown, enrolled, undulate. Hymonophore white, cream to brown; pores fine, rounded to angular, 6–7 per mm. Context in pileus pale buff, corky, up to 1 mm thick. Tube continuous with the context, up to 0.5 mm thick.

L = 7.52 μm, W = 4.25 μm, Q = 1.78 (n = 20/1).

Habitat: solitary to gregarious on dead wood of hardwood.

Material examined: KOREA, Gyeongsangbuk-do, Ulleung-gun, Na-ri basin, on fallen hardwood branch, 14 August 2012, Y. W. Lim, W. J. Kim & S-Y. Oh (SFC20120814-33, holotype); KOREA, Gangwon-do, Inje-gun, on rotten wood below litter layer, 1 July 2014, Y. W. Lim & H. J. Cho (SFC2040701-19, paratype).

GenBank Numbers ITS:KY038466.

Notes: Polyporus parvovarius is similar to P. badius, P. elegans and P. varius in its central stipitate basidiocarps, blackish stipe, and microscopic features. Simple septate generative hyphae separate P. badius from the other species. P. parvovarius has larger basidia (23.8–26.3 × 7.4–8.5 μm) than P. elegans (15–20 × 6–7 μm) and P. varius (18–23 × 5–7 μm). Phylogenetic analysis of the ITS region showed that P. parvovarius is closely related to P. brevibasidiosus (Fig. 178). However, they are distinguishable by pore, basidia, and basidiospore size. P. parvovarius has larger than those of P. brevibasidiosus.

In a phylogenetic analysis, P. badius formed a separate clade within the Melanopus clade, but P. subdictyopus is located in a sister clade together with P. dictyopus (Fig. 178). Basidiocarps shape and microscopic features of P. dictyopus are hard to distinguish except its pantropical distribution. One or two oil drops in the basidiospores of P. subdictyopus differentiate it from P. dictyopus.

GenBank Numbers SFC20120814-41 ITS:KY038467. SFC20150902-99 ITS:KY038481.

Notes: Polyporus ulleungus is commonly found in the Na-ri Basin of Ulleung Island and has larger basidiocarps (SFC20120814-41; 110 mm across) than other species collected in inland area (SFC20150902-99; 35 mm across). Polyporus ulleungus is most similar to P. koreanus and P. melanpus. It has larger pore (5–6 mm) than those of P. koreanus (6–7 mm) and P. melanpus (6–8 mm). In a phylogenetic analysis, P. ulleungus formed a distinct clade with strong support (100% ML, Fig. 179) and clearly separated from P. koreanus and P. melanpus (Fig. 178).

Wolfiporia Ryvarden & Gilb.

Wolfiporia is a genus of mushrooms in the family Polyporaceae. The genus was introduced by Ryvarden and Gilbertson (1984) to contain the type species Wolfiporia cocos (currently known as W. extensa) and W. dilatohypha (Fig. 185).

Specimen examined: CHANA, Hainan Province, Ledong County, Jianfengling Nature Reserve, On dead angiosperm tree, 1 June 2015, Dai 15269 (BJFC019380, holotype).

GenBank Numbers ITS:KX354451.

Notes: The phylogenetic analysis of ITS sequence (Fig. 186) shows that the new species, Wolfiporia pseudococos, is closely related to W. cocos (F.A. Wolf) Ryvarden & Gilb, the type species of the genus Wolfiporia. Sequence data from three specimens of W. Cocos also clustered in a distinct lineage with strong support (100% BS, 1 BYPP), and the sequence of the new species formed a terminal lineage. Morphologically, Wolfiporia pseudococos is distinguished from W. cocos by the presence of cystidioles and larger basidiospores (7.9–9.5 × 3–3.8 µm vs. 6.5–8.1 × 2.8–3.1 µm). In addition, Wolfiporia cocos usually grows on conifers in temperate areas, but Wolfiporia pseudococos has a distribution in tropics and growing on angiosperm trees.

Psathyrellaceae Locq.

The family Psathyrellaceae is a family of dark-spored agarics that generally have rather soft, fragile fruiting bodies, and are characterized by black, dark brown, rarely reddish, or even pastel-coloured spore prints.

Coprinopsis P. Karst., Acta Soc. Fauna Flora Fenn. 2 (1): 27 (1881)

During the last 25 years, molecular phylogenetic analyses have made great impact on our understanding of phylogenetic relatonships among coprinoid fungi (Hopple and Vilgalys 1994, 1999; Moncalvo et al. 2002). The analyses have showed that the genus Coprinus Pers. sensu lato is not monophyletic. A minority of Coprinus species (including the type species C. comatus (O.F. Müll.) Pers.) is clustered near the genus Agaricus L., while the great majority of Coprinus species is grouped into three clades closely related to the genus Psathyrella (Fr.) Quél. Based on molecular studies, Redhead et al. (2001) transferred the majority of Coprinus species into three genera (Coprinellus P. Karst., Coprinopsis, and Parasola Redhead, Vilgalys & Hopple) within the newly proposed family Psathyrellaceae Vilgalys, Moncalvo & Redhead. Consequently, the genus Coprinopsis includes five subsections of Coprinus sensu lato, Alachuani Singer, Atramentarii (Fr.) Konrad & Maubl., Lanatuli J.E. Lange, Narcotici Uljé & Noordel., and Nivei Citérin. Further phylogenetic research (Larsson and Örstadius 2008; Padamsee et al. 2008; Örstadius et al. 2015) revealed that the genus Psathyrella is not monophyletic either. Based on these studies, some Psathyrella species belong to the genus Coprinopsis (Fig. 188).

GenBank Number ITS:KX869912.

Notes: Based on a megablast search of NCBIs GenBank numbers nucleotide database, the closest hits using the ITS1-5.8S-ITS2 sequence for our holotype collection (CNF 1/7253, GenBank Numbers KX869912) are Coprinopsis (Coprinus) cortinata (J.E. Lange) Gminder (GenBank Numbers JF907847; Identities = 619/702 (88%), Gaps = 29/702 (4%)), Coprinopsis (Coprinus) bellula (Uljé) P. Roux & Eyssart. (GenBank Numbers FN430682; Identities = 621/705 (88%), Gaps = 30/705 (4%), and Coprinopsis utrifer (Watling) Redhead, Vilgalys & Moncalvo (GenBank Numbers FN396410; Identities = 609/688 (89%), Gaps = 28/688 (4%)). Other three collections of C. cerkezii (CNF 1/5209, 1/5216, 1/7252) have identical ITS and LSU sequences. The phylogenetic analysis using maximum likelihood method was performed with MEGA6 software. The ITS sequence from the holotype of Coprinopsis cerkezii was combined with sequences of all closely related species and some other taxa of the genus Coprinopsis downloaded from GenBank number database. Analysed sequences belong to the species from subsections Alachuani, Atramentarii, Lanatuli, Narcotici, and Nivei (Uljé 2005) of the genus Coprinus sensu lato, as well as to a few Coprinopsis species transferred from the genus Psathyrella (Örstadius et al. 2015). Sequences of Coprinellus species (C. xanthothrix (Romagn.) Vilgalys, Hopple & Jacq. Johnson and C. domesticus (Bolton) Vilgalys, Hopple & Jacq. Johnson) were used as outgroup. In phylogenetic analysis Coprinopsis cerkezii clustered with other members of subsect. Nivei of the genus Coprinus sensu lato (Fig. 188), in accordance with its morphological characters.

Coprinopsis cerkezii is primarily characterised by small and delicate basidiocarps, a strongly plicate-sulcate pileus with an orange-brown to rusty-orange upper veil, narrow and elongated spores without myxosporium, an abundance of spherical pileal velar elements lacking nipple-shaped warts, an absence of pleurocystidia and clamp-connections, and by living on dung. Comparison of C. cerkezii with similar taxa is based on descriptions in the following literature: Bisby et al. (1929), Orton and Watling (1979), Pegler (1986), Doveri (2004), Uljé (2005). Five species morphologically similar to C. cerkezii, C. bellula, C. candidata (Uljé) Gminder & T. Böhning, C. coniophora (Romagn.) Redhead, Vilgalys & Moncalvo, C. cortinata, and Coprinus furfurellus (Berk. & Broome) Pegler, differ by living on soil or wood, by presence of clamp-connections, and by absence of orange-brown tones in pileus. From above mentioned species, Coprinus furfurellus possess the most similar basidiospores (6–7 × 3.5–4 µm), but the average Q is smaller (1.73). Three other similar species live on dung as Coprinopsis cerkezii. Coprinus parvisporus Buller differs by having white pileus, less elongated spores (6 × 3.5 µm), presence of pleurocystidia, and larger spherical elements of pileal veil (60–80 µm). Coprinopsis pseudcortinata (Cacialli, Caroti & Doveri) Doveri, Granito & Lunghini differs by having white to greyish pileus, broader (3.5–4.5 µm) and less elongated spores (Q = 1.5–2.05), presence of pleurocystidia and smaller number of lamellae (L = 6–12). Coprinopsis utrifer differs by having broader (4–5.5 µm) and less elongated spores (Q = 1.3–1.7) and by presence of clamp-connections and pleurocystidia. ITS Sequences of Coprinopsis candidata, C. pseudcortinata, Coprinus furfurellus, and C. parvisporus are not included in phylogenetic analysis since the sequences of these species are not present in GenBank.

Russulales Pers.

Russulaceae Lotsy

Russulaceae is one of the dominant and morphologically diverse families of mushrooms in the order Russulales, with roughly 1900 known species and a worldwide distribution (Kirk et al. 2008). Apart from its three corticoid genera, i.e. Boidinia, Gloeopeniophorella and Pseudoxenasma (Larsson and Larsson 2003; Miller et al. 2006), this family has four predominantly agaricoid genera: Lactifluus, Lactarius, Multifurca and Russula (Buyck et al. 2008, 2010), some of which may also contain secotioid-hypogeous or pleurotoid species.

Russula Pers.

The genus Russula Pers. has a worldwide distribution and can be easily identified with its colourful fruiting bodies (Kirk et al. 2008). Russula is widely distributed from Western Europe to North America in the northern hemisphere (Romagnesi 1967; Singer 1986; Sarnari 1998; Miller and Buyck 2002; Bau et al. 2008). The genus contains more than 200 species generally accepted in Europe (Sarnari 1998, 2005) and more than 750 species worldwide (Kirk et al. 2008). Keys to Russula being complex since of this huge taxonomic diversity. They play a crucial beneficial role in forest ecosystems as ectomycorrhizal symbionts (Li et al. 2013a). Russula species were used as traditional food and medicine in China for a long history. Twenty-two medicinal species and 82 edible species have been reported in China (Dai et al. 2009; Li et al. 2010). Southwestern China represents one of the world’s biodiversity “hotspots” and has a high diversity of macro-fungi (Yuan and Dai 2008), but only a few russulacean species have been identified from this region. However, some new species and varieties have been reported from Southern and Southwestern China (Wang et al. 2009). In this contribution one new species belong to genus Russula is introduced from Guizhou Province, China (Fig. 191).

GenBank Number ITS:KY195927.

Notes: Russula yanheensis is morphologically and phylogenetically close to Russula pulchra Burl. Russula pulchra has 50–100 mm diameter pileus, stipe 30–70 mm long, ellipsoid basidiospores 6.5–9 × 5.5–7.5 µm; and pilocystidia absent (Binion et al. 2008), but R. yanheensis has 32–70 mm diameter pileus, stipe 23–42 mm long, ellipsoid to subglobose to globose basidiospores 5.8–8.3 × 4.8–7.3 µm, i.e. having smaller pileus, stipe and basidiospores, and the different shapes of basidiospores, presence of pilocystidia. Russula yanheensis is also morphologically similar to R. flavisiccans Bills but the latter species differs from our species by its pileus colour, pilocystidia and cheilocystidia shapes and sizes, further, the stipe never flushes with pink (Kuo and Methven 2014). Further, R. yanheensis is phylogenetically closely related to R. sichuanensis G.J. Li & H.A. Wen, but its morphological characteristics are very different from the latter species by its colour, pilocystidia and cheilocystidia shapes and sizes.

Dacrymyces chiangraiensis Ekanayaka, S.C. Karunarathna, Q. Zhao & K D. Hyde, sp. nov.

Index Fungorum number: IF552549; Facesoffungi number: FoF 2696, Fig. 196

Etymology: Name reflects the province, where the type species was collected

Holotype: MFLU 16-0572

Saprobic on wood, stems and twigs. Sexual morph Basidiomata 478–482 × 908–915 µm (\( \bar{x} \) = 480.8 × 911.6 µm, n = 10) superficial, mostly solitary, sometimes gregarious, pulvinate, yellow to orange. Sterile parts of basidiocarps covered with simple or branched, tightly packed, cylindrical, septate, hyaline, thin-walled marginal hyphae. Internal hyphae branched, thin walled, gelatinous, septate, hyaline, loosely packed, clamp connections absent. Hymenium composed of dikaryophyses and basidia. Dikaryophyses 2–5.5 µm (\( \bar{x} \) = 4 µm, n = 20) branched, septate, thick-walled, hyaline. Hymenium hyaline, limited to the upper surface of the basidiocarp. Probasidia 32–53 × 7–10 µm (\( \bar{x} \) = 41.4 × 8.5 µm, n = 20) hyaline, guttulate, cylindrical to clavate, thin-walled, becoming bifurcate. Basidiospore 19–23 × 6.5–8 µm (\( \bar{x} \) = 20.9 × 7.3 µm, n = 20), allantoid, somewhat bent, hyaline, with many transverse septa, smooth walled. Asexual morph undetermined.

Material examined: THAILAND, Mae Fah Luang University, Chiang Rai Province, 22 December 2014, A.H. Ekanayaka, (MFLU 16-0572, holotype).

GenBank Number ITS:KY498587.

Notes: Dacrymyces chiangraiensis is phylogenetically close to D.san-augustinii. However, they are separated with strong bootstrap support. Morphologically D. chiangraiensis is similar to D. san-augustinii in having yellow to orange pulvinate basidiomata, but they differ in the size of the basidiomata and colour of probasidia and basidiospores. Dacrymyces san-augustinii has larger basidiomata (1–2 mm high, 1–3 mm diam.) with pale yellow probasidia, and subhyaline, smaller basidiospores (15.5–23.6 × 4.6–6.8 µm) (McNabb 1973). Dacrymyces chiangraiensis differs from D. novae-zelandiae in having yellow to orange non-gelatinized basidiomata with smaller probasidia (Ellis and Ellis 1990; Shirouzu et al. 2009)

Femsjonia Fr.

The genus Femsjonia was established by Fries with the type species Femsjonia luteoalba Fr. However, the systematic position of this genus was not clear and linked with Peziza radiculata as the appearance of fruiting body is similar to discomycetes (McNabb 1965). Currently this genus classified within Dacrymycetaceae (Dacrymycetales, Dacrymycetes, Agaricomycotina). The genus Femsjonia is characterized by discoid, brightly coloured basidiomata with thick-walled internal hyphae and globose to sub-globose basidia (McNabb 1965; Shirouzu et al. 2009).

Femsjonia monospora Ekanayaka, S.C. Karunarathna, Q. Zhao & K.D. Hyde, sp. nov.

Index Fungorum number: IF552550; Facesoffungi number: FoF 2697, Fig. 197

Etymology: Name reflects the aseptate basidiospores.

Holotype: MFLU 16-0608

Saprobic on wood, stems and twigs. Basidiomata superficial, gregarious, discoid, sessile, bright yellow, orange near the base, sterile surface rough tomentose, whitish at the margins of the hymenial surface. Hymenium yellow. Internal hyphae branched, thin-walled, septate, hyaline, loosely packed. Probasidia 100–150 × 7–10 µm (\( \bar{x} \) = 139.6 × 8.2 µm, n = 20) cylindrical, yellow, thin-walled, becoming bifurcate. Basidiospores 25–30 × 10–15 µm (\( \bar{x} \) = 28.5 × 12.5 µm, n = 20), subglobose, guttulate, aseptate, yellowish, smooth-walled.

Material examined: CHINA, Yunnan province, Kunming, 10 November 2015, S. C. Karunarathna (NB130), (MFLU 16-0608, holotype).

GenBank Number ITS:KY498588.

Notes: Femsjonia monospora distinct from all the other species in the genus by having larger probasidia and aseptate, guttulate basidiospores (McNabb 1965; Liu et al. 1988; Shirouzu et al. 2009). The phylogenetic comparisons among Femsjonia species are not possible due to the lack of sequence data.

Tremellales Fr.

Tremellaceae Fr.

This family was erected by Fries in 1821 based on macromorphology of its members (Fries 1821). This family currently comprises 18 genera and 250 valid species (Kirk et al. 2008).

Tremella Pers.,

Tremella was one of the original genera created by Linnaeus in his Species Plantarum of 1753. All Tremella species are parasites of other fungi and most produce anamorphic yeast states. Basidiocarps, when produced, are gelatinous and are colloquially classed among the “jelly fungi”. Over 100 species of Tremella are currently recognized worldwide (Kirk et al. 2008). Two species, T. fuciformis and T. aurantialba, are commercially cultivated for food (Fig. 198).

Tremella fuciformis Berk., Hooker’s Journal of Botany and Kew Garden Miscellany 8: 277 (1856)

Facesoffungi number: FoF 3146, Figs. 199, 200

Basidiocarps foliose, lobes caespitose, wet, gelatinous but fairly hard, crisped, composed of graceful lobes, lobes generally very thin, flower like, translucent whitish, up to about 8 cm across and 5 cm high, surface smooth and shiny, generally associated with Hypoxylon sp. Spore print white. Basidiospores 7–15 × 5–9 µm, Q_m = 1.2–1.6 µm, broadly ellipsoid to ellipsoid, smooth, often germinating by repetition, budding or sometimes germ tubes. Basidia mostly 4–spored but occasionally 2 or 3 spored, becoming longitudinally 4–septate with maturity, probasidia typically clavate becoming subglobose to ellipsoid with maturity, 11–16 × 8–14 µm, with sterigmata up to 50 × 4 µm. Conidia absent. Vesicles absent. Hyphidia absent. Hyphae 2–6 µm diam. in inner part of basidiocarps, close to substrate 12 µm diam. Haustorial hyphae in basal part close to substrate, often branched. Clamp connections present.

Habit, habitat and distribution: Tremella fuciformis, following its host, fruit bodies are typically found on dead, attached or recently fallen branches of broadleaf trees. This fungus commonly prefers tropical and subtropical ecosystems, May–September. This species is mainly in tropical and subtropical ecosystems, but does occur temperate areas in Asia including Thailand; Laos and China, and North America. It is found in South and Central America, the Caribbean, parts of North America, sub-Saharan Africa, southern and eastern Asia, Australia, New Zealand and the Pacific Islands. Our collection was found on a fallen dead tree branch near Hanthana Mountains Range, Peradeniya, Sri Lanka.

Specimens examined: SRI LANKA, Kandy District, Hanthana Mountains Range, 1 June 2012, Samantha C. Karunarathna (MFLU 12-1895, new record).

GenBank Number ITS:KY649468.

Notes: The species is distributed mainly in tropical and subtropical areas, but extends into temperate areas in Asia and North America. It is known throughout South and Central America, the Caribbean, parts of North America, sub-Saharan Africa, southern and eastern Asia, Australia, New Zealand, and the Pacific Islands. This is the first report of T. fuciformis with the molecular phylogenetic confirmation from Sri Lanka.
