One of the ecological function of mangrove forests is a habitat for mosquitoes that cause malaria (Anopheles sp.). Epidemic of malaria could increased as a result of mangrove degradation. The damage of mangrove forests stimulate Anopheles sp. migrate to other habitats such as settlements, that become malaria vector. The purpose of this research was to determine the effect of mangrove forest ecosystems both intrinsic and extrinsic factors in immunity to malaria. This research was conducted on June 2014 in the Muara Gading Mas Village, Bandar Negeri, Sriminosari, and Margasari, Sub-district Labuhan Maringgai, District East Lampung. The data were collected through interviews and survey/observations method. The impact of each variable used binary logistic regression models. Parameter optimization used software Minitab 16. The result of research have been demonstrated that there is influence both intrinsic and extrinsic factors in immunity to malaria in mangrove forest. Factors that i...

This review summarizes recent literature (2000-2015) on the synthesis and pharmaceutical properties of pyrrolopyrimidines. These modified pyrimidine bases, fused to a pyrrole ring, and their corresponding nucleosides display a broad applicability in medicinal chemistry. This overview is divided into three main sections, according to the respective isomers: pyrrolo[2,3-d]pyrimidines, pyrrolo[3,2-d]pyrimidines, and pyrrolo[3,4-d]pyrimidines. Each section contains a description of common retro-synthetic strategies, with particular attention for newly reported synthetic entries to the scaffold. Next, the synthetic strategies and the ways in which the scaffolds can be further modified are exemplified according to the biological properties of the obtained products.

Notes — Castanediella was introduced for idriella-like fungi, distinguished by having branched conidiophores giving rise to straight or slightly curved conidia (Crous et al. 2015b, 2017b, Hernández-Restrepo et al. 2016, 2017). Castanediella tereticornis is phylogenetically distinct from the 12 species presently accepted in the genus, all of which are known from DNA sequence data. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Castanediella cagnizarii (GenBank NR_156294.1; Identities = 543/555 (98 %), 6 gaps (1 %)), Castanediella hyalopenicillata (GenBank NR_156309.1; Identities = 491/504 (97 %), 5 gaps (0 %)) and Pidoplitchkoviella terricola (GenBank MH861046.1; Identities = 457/498 (92 %), 8 gaps (1 %)). Falcocladium africanum Crous, sp. nov. Etymology. Name refers to Africa, the continent where this fungus was collected. Classiﬁcation — Falcocladiaceae, Falcocladiales, Sordariomycetes.

Wingfield, HPC 2166, CPC 34007, ITS and LSU sequences GenBank MK047420.1 and MK047471.1. Notes — Falcocladium represents a genus of hyphomycetes associated with leaf litter, or considered to be weak foliar pathogens of Eucalyptus (Crous et al. 1994, 1997). Four species are presently known in the genus, having been collected on eucalypt leaves in Asia, Australia and South America. Falcocladium africanum represents the ﬁrst species described from Africa, and differs from F. thailandicum (sphaeropedunculate vesicles, 6 –7 µm diam, aseptate conidia, (19 –)20 – 23(– 24) × 1.5(– 2) µm; Crous et al. 2007b) in vesicle shape, and having smaller, 0 –1-septate conidia. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of CPC 34050 had highest similarity to Falcocladium thailandicum (GenBank NR_156241.1; Identities = 638/656 (97 %), 6 gaps (0 %)), Falcocladium sphaeropedunculatum (GenBank EU040220.1; Identities = 567/661 (86 %), 43 gaps (6 %)) and Falcocladium multivesiculatum (GenBank JF831936.1; Identities = 420/466 (90 %), 15 gaps (3 %)). The ITS sequences of CPC 34007, 34017 and 34050 are identical. Closest hits using the rpb2 sequence of CPC 34050 had only distant hits with Fusarium species (less than 80 % sequence similarity). The rpb2 sequences of CPC 34017 and 34050 are identical as no other rpb2 sequences are available for Falcocladium species. Pedro W. Crous & Johannes Z.

Notes — Zasmidium and allied genera (Periconiella, ramichloridium-like, rasutoria-like, stenella-like, Verrucisporota) were recently revised by Videira et al. (2017), who presented an emended, wider circumscription of Zasmidium than that previously accepted by Braun et al. (2013). Several species are known to be associated with leaf spots on Eucalyptus, which are allied, but phylogenetically distinct from Z. corymbiae, which is more ramichloridium-like in morphology, having a terminal rachis on its conidiogenous cells, and aseptate conidia. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of CPC 33349 had highest similarity to Zasmidium strelitziae (GenBank NR_156514.1; Identities = 509/543 (94 %), 13 gaps (2 %)), Zasmidium commune (GenBank KY979762.1; Identities = 503/542 (93 %), 10 gaps (1 %)) and Zasmidium pseudovespa (GenBank NR_137548.1; Identities = 473/513 (92 %), 10 gaps (1 %)).

Notes — Harknessia (Harknessiaceae; Crous et al. 2012a) is a genus of appendaged coelomycetous fungi that is commonly isolated from Myrtaceae and Proteaceae. Harknessia was treated by Marin-Felix et al. (2019), who accepted 38 species, recognising the majority as either endophytes, saprobes or foliar pathogens of minor importance. Harknessia corymbiicola represents a phylogenetically distinct species in the H. weresubiae species complex, being characterised by fusoid, apiculate conidia that lack striations, and have (50–)65–80(–90) µm long basal appendages. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Harknessia platyphyllae (GenBank NR_155191.1; Identities = 625/640 (98 %), 11 gaps (1 %)), Harknessia banksiae (GenBank NR_155188.1; Identities = 625/641 (98 %), 5 gaps (0 %)) and Harknessia banksiigena (GenBank NR_155189.1; Identities = 614/630 (97 %), 7 gaps (1 %)).

Etymology. Name refers to Pelargonium, the host genus from which this fungus was isolated. Classiﬁcation — Nectriaceae, Hypocreales, Sordariomycetes. Mycelium consisting of hyaline, smooth, branched, septate, 2.5–3.5 µm diam hyphae. Conidiomata sporodochial, sessile on agar, 50 – 200 µm diam, basal stroma of cells arising from wide hyphae, 8–15 µm diam, giving rise to tightly aggregated cluster of primary branches, aseptate, 1 0 – 20 × 4 –7 µm, forming several secondary branches, 10–15 × 4–5 µm, giving rise to erect, tertiary and quarterly branches, 10 –17 × 3 – 4 µm, forming 1– 3 cymbiform to subcylindrical phialides with periclinal thickening, 12–25 × 3.5–4 µm.

(Geraniaceae), 1 Feb. 2010, P.W. Crous (holotype CBS H-23754, culture ex-type CBS 145054, ITS, LSU, his3, rpb2 and tub2 sequences GenBank MK047426.1, MK047477.1, MK047530.1, MK047537.1 and MK047578.1, MycoBank MB828170). Notes — The genus Thelonectria was established for a genus of Nectriaceae with cylindrocarpon-like asexual morphs (Chaverri et al. 2011) and presently includes approximately 40 species that are known to be saprobes or pathogens of hardwood trees and shrubs. Thelonectria pelargonii, which is phylogenetically distinct from other species in the genus, was associated with roots of a Pelargonium sp. in South Africa, but presently nothing is known about its ecology. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Thelonectria veuillotiana (GenBank KJ022014.1; Identities = 462/493 (94 %), 14 gaps (2 %)), Thelonectria westlandica (GenBank JQ403327.1; Identities = 480/515 (93 %), 11 gaps (2 %)) and Cylindrocarpon olidum (GenBank KC427020.1; Identities = 515/566 (91 %), 29 gaps (5 %)).

Etymology. Name refers to Angola, the country where this species was collected. Classiﬁcation — Didymosphaeriaceae, Pleosporales, Dothideomycetes. Mycelium consisting of hyaline, septate, branched, 2 – 3.5 µm diam hyphae. Conidiophores solitary on aerial mycelium, but also becoming aggregated on agar surface, giving rise to sporodochia, up to 250 µm diam; conidiophores subcylindrical, branched or not, 1– 3-septate, 10 – 25 × 2 – 3.5 µm, pale brown, smooth to verruculose. Conidiogenous cells smooth, pale brown, subcylindrical, proliferating percurrently, 7–15 × 2 – 3.5 µm; conidiogenesis peculiar in that the tip of the conidiogenesis cell is covered by the basal cap attached to conidia, and this is free from the conidiogenous cell itself. In young conidiogenous cells the conidiogenous cell is swollen at the apex, and the basal conidial cap appears to be attached to the tip, but later it is clearly a cap covering the apex of the conidiogenous cell. Conidia solitary, medium to dark brown, narrowly fusoid, apex obtuse, base with basal cup-shaped brown appendage; 3-septate, with two central cells somewhat darker than the apical and basal cell, (28 –) 30 – 34(– 37) × (7–)8(– 9) µm; wall covered in tubular warts, 1– 3 × 1–1.5 µm (tubes open once mature); basal cap-like appendage brown, 2 – 3 × 3– 4 µm. Culture characteristics — Colonies spreading, with moderate aerial mycelium, covering dish after 2 wk at 25 °C. On MEA, PDA and OA surface mouse grey to olivaceous grey, reverse olivaceous grey.

Notes — Pseudopithomyces contains around 10 species, distinguished from Pithomyces s.str. by having fusoid, echinulate to verruculose conidia that are visible as brown to black colonies on the host. In contrast, Pithomyces produces obovate to ovoid, verruculose, pale brown conidia that form whitish to yellowish colonies on the host (Ellis 1971). Colonies of Pseudopithomyces angolensis were small, black and shiny on leaves, and were initially assumed to represent packets of insect eggs. Morphologically, it is distinct from P. chartarum (conidia with 3 transverse and 1–2 vertical septa, 18–29 × 10–17 µm; Ellis 1971) in having longer, narrower conidia that lack vertical septa. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hit using the ITS sequence had highest similarity to Pithomyces chartarum (strain CBS 485.71, GenBank MH860227.1; Identities = 596/601 (99 %), 1 gap (0 %)) and several other sequences labelled as Pithomyces chartarum or Pseudopithomyces chartarum; however, several other cultures of this species are more distant (e.g., CBS 805.72, CBS 679.71 and CBS 712.70, GenBank MH860611.1, MH860299.1 and MH859914.1; Identities = 588/607 (97 %), 7 gaps (1 %)).

Colour illustrations. Wolkberg, South Africa; symptomatic leaf, conidiogenous cells and conidia. Scale bars = 10 µm. Notes — Melanconiella presently includes approximately 20 species (Voglmayr et al. 2012), most of which occur on recently dead twigs and branches of Betulaceae, occurring in the north temperate zone. Asexual morphs of Melanconiella have in the past been described in Melanconium, although the latter genus is in need of revision (Sutton 1980). Morphologically, there is little to choose between Melanconiella and Neomelanconiella, although N. combreti occurs on leaves of Combretaceae, and in the Southern Hemisphere. Neomelanconiella combreti clusters with an isolate identiﬁed as Cryptodiaporthe vepris (AR 3559, on Rubus idaeus (Rosaceae), Austria), although the latter genus is now a synonym of Plagiostoma (Mejía et al. 2011). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Melanconiella ellisii (GenBank JQ926269.1; Identities = 404/449 (90 %), 22 gaps (5 %)), Sphaeronaemella fragariae (GenBank AY271808.1; Identities = 394/440 (90 %), 16 gaps (4 %)) and Melanconiella spodiaea (GenBank JQ926299.1; Identities = 400/448 (89 %), 20 gaps (4 %)).

Etymology. Name refers to Melastoma, the host genus from which this fungus was isolated. Classiﬁcation — Australiascaceae, Chaetosphaeriales, Sordariomycetes. Mycelium consisting of pale brown, smooth to ﬁnely roughened, branched, septate, 2.5 – 4 µm diam hyphae. Conidiophores solitary, erect, subcylindrical, brown, smooth, rarely branched at base, becoming paler brown toward apex, straight, 2 – 3(– 8)-septate, 90 – 250 × 6 –10 µm. Conidiogenous cells terminal, pale brown, smooth, subcylindrical with apical taper to truncate apex, 40 – 55 × 6 –7 µm, phialidic with prominent periclinal thickening at apex, 3 – 4 µm diam. Conidia aseptate, occurring in unbranched chains (–30), ellipsoid to narrowly obovoid, hyaline, smooth, guttulate, apex obtuse, tapering at base to truncate hilum, 2 µm diam, (17–)18 –19(– 20) × (7.5 –)8 µm.

Notes — Monilochaetes (sexual morph Australiasca) is a hyphomycetous genus with solitary, erect, sometimes curved or geniculate, dark brown conidiophores with prominently darkened septa, terminal, wide monophialides with a shallow collarette, and aseptate, rarely septate, hyaline conidia adhering in basipetal chains or heads (Réblová et al. 2011). Using the key of Réblová et al. (2011), M. melastomae is similar to M. guadalcanalensis (conidia 18 – 21 × 6 – 9 µm), although the former differs by forming shorter conidiophores and extremely long conidial chains, and is also phylogenetically distinct. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Australiasca queenslandica (GenBank KP204397.1; Identities = 463/472 (98 %), no gaps), Monilochaetes nothapodytis (GenBank MF153475.1; Identities = 476/499 (95 %), 9 gaps (1 %)) and Australiasca laeensis (GenBank EF029187.1; Identities = 506/547 (93 %), 19 gaps (3 %)).

Etymology. Name refers to Corymbia, the host genus from which this fungus was isolated. Classiﬁcation — Dothideaceae, Dothideales, Dothideomycetes. Conidiomata pycnidial, separate, obovoid, papillate, brown, with central ostiole, 100 –150 µm diam; wall of 4 – 8 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells lining the inner cavity, ellipsoid, hyaline, polyphialidic, with 1– 3 loci per conidiogenous cell, 5 –10 × 4 – 5 µm.

Notes — Dothiora was recently treated by Crous & Groenewald (2016, 2017). Ascostromata were shown to lack pseudoparaphyses, have bitunicate asci with hyaline, transversely septate ascospores (rarely with vertical septa). Conidiomata are pycnidial, conidiophores reduced to hyaline, phialidic conidiogenous cells, and conidia aseptate, hyaline, smooth, subcylindrical to ovoid or oblong, forming a hormonema-like synasexual morph.

Notes — Alfaria was established for a fungus causing a disease on Cyperus esculentus in Spain, and presently contains close to 20 species (Crous et al. 2014a, 2018a, Lombard et al. 2016). Alfaria tabebuiae is phylogenetically closely related to A. acaciae (conidia (6 –)8 –10(–12) × (2.5 –)3 µm; Crous et al. 2018a), although it has shorter conidia, and longer setae. Several isolates identiﬁed as Amerosporium spp. cluster in the Alfaria clade. However, Amerosporium has unilocular, spherical conidiomata, and is distinct from the sporodochial conidiomata of Alfaria. Synapomorphies between the genera are pigmented setae, phialidic conidiogenous cells and pigmented, aseptate conidia. The morphology of these ‘Amerosporium’ isolates will be resolved in a later study. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of CPC 34038 had highest similarity to Alfaria acaciae (GenBank NR_158363.1; Identities = 572/582 (98 %), 5 gaps (0 %)), Alfaria cyperi-esculenti (GenBank KJ869143.1; Identities = 575/591 (97 %), 10 gaps (1 %)) and Alfaria thymi (GenBank NR_154714.1; Identities = 568/587 (97 %), 13 gaps (2 %)).

Etymology. Name refers to Laurus, the host genus from which this fungus was isolated. Classiﬁcation — Vermiculariopsiellaceae, Vermiculariopsiellales, Sordariomycetes. Sporodochia developing on OA and PDA, erumpent, crystalline, up to 450 µm diam, with brown, erect setae dispersed throughout sporodochium, thick-walled, smooth-walled, straight to flexuous, 100 – 300 × 4 – 5 µm, 8 – 20-septate, tapering to an obtuse apex and with bulbous base, 7– 9 µm diam, forming a series of lateral branches (up to 100 µm long) that again branch once with tertiary branch (up to 120 µm long). Conidiogenous cells phialidic, developing in a cluster around the base of setae, pale brown, smooth, subcylindrical with apical taper with periclinal thickening and minute collarette, 1– 2 µm long, 20 – 25 × 3–3.5 µm.

Culture characteristics — Colonies flat, spreading, with sparse aerial mycelium, folded surface, and even, lobate margin, reaching 25 mm diam after 2 wk at 25 °C. On MEA surface pale mouse grey, reverse mouse grey. On PDA surface sepia, reverse brown vinaceous. On OA surface mouse grey. Typus.

Notes — Species of Vermiculariopsiella produce sporodochia with brown, erect setae, stromatic, sub-hyaline conidiophores, phialidic conidiogenous cells, and hyaline, aseptate conidia (Crous et al. 2014a). There are presently more than 16 species known in the genus. Vermiculariopsiella lauracearum is morphologically distinct from known species based on its long, branched setae, and small conidia. Vermiculariopsis circinotricha, an apparent coelomycete (Chaetomella complex), was described from leaves of Laurus ‘canariensis’ collected in Madeira (branched setae, conidia cylindrical, 14 –19 × 1–1.5 µm). However, Sutton & Sarbhoy (1976) could not locate any type material, and hence the taxonomy of the genus has remained unresolved. Based on the original description and current information about the sexual morph of Vermiculariopsiella, it could well be that the illustrated black, ellipsoid sporocarp was of an ascoma (e.g., see V. dichapetali ), in which case Vermiculariopsis would represent an older name for the genus Vermiculariopsiella. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Vermiculariopsiella microsperma (GenBank KY853478.1; Identities = 530/546 (97 %), 7 gaps (1 %)), Vermiculariopsiella pediculata (GenBank MH866028.1; Identities = 530/556 (95 %), 11 gaps (1 %)) and Vermiculariopsiella eucalypti (GenBank NR_154637.1; Identities = 514/540 (95 %), 5 gaps (0 %)).

Mycelium consisting of branched, septate, pale olivaceous, smooth, 2–3 µm diam hyphae. Conidiophores solitary, erect, medium brown, smooth-walled, flexuous, arising from superﬁcial hyphae, subcylindrical, rarely branched, multiseptate, 200–500 × 5–6 µm, with basal cell extending from hyphae or globose, up to 8 µm diam, lacking rhizoids. Conidiogenous cells integrated, subcylindrical, medium brown, smooth-walled, terminal and intercalary, 20–40 × 4–5 µm, polyblastic, with flat-tipped loci, 2–2.5 µm diam, not thickened nor darkened. Conidia in branched chains, subcylindrical to narrowly fusoid with obtusely rounded ends, hila truncate, 1–1.5 µm diam, unthickened, nor darkened, 3(–7)-septate, ﬁnely roughened, medina cells medium brown, end cells pale brown, (23–)30–35(–47) × (4–)5 µm.

Right column, Anungitopsis lauri, conidiophores, conidiogenous cells and conidia. Scale bars = 10 µm. Notes — Anungitea is a genus of hyphomycetes deﬁned as having dark, solitary conidiophores, with a denticulate head with flattened conidiogenous scars that are unthickened and not darkened, and chains of cylindrical, 1-septate subhyaline conidia (Sutton 1973). Anungitopsis includes taxa with indistinguishable scars arranged in a rachis, and Neoanungitea is intermediate between these two genera, having a rachis, but with flat-tipped loci (Crous et al. 2017b). Crous et al. (2018a) introduced the genus Pseudoanungitea for species phylogenetically distinct from Anungitea s.str., having terminal and intercalary conidiogenous cells, and refractive, thickened scars that give rise to short conidial chains with somewhat darkened and refractive hila. Anungitopsis lauri is phylogenetically distinct from those species presently known from their DNA sequence data. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Anungitopsis speciosa (GenBank EU035401.1; Identities = 601/614 (98 %) and Neoanungitea eucalypti (GenBank NR_156383.1; Identities = 495/607 (82 %), 41 gaps (6 %)).

Notes — Myrmecridium is a ramichloridium-like genus with hyaline mycelium, and relatively unpigmented, pimple-like denticles (Arzanlou et al. 2007). The genus presently contains 12 species, all of which are known from their DNA. Species are distinguished based on conidium and conidiophore morphology, as well as DNA phylogeny (Crous et al. 2015a, 2016a). Myrmecridium sorbicola was recently introduced by Crous et al. (2018a), who commented on the fact that it was distinct from known species of Myrmecridium in having septate conidia. In the present additional species are added (also with septate conidia), resolving this clade to represent a new genus, clustering sister to Myrmecridium s.str. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Myrmecridium sorbicola (GenBank MH107901.1; Identities = 502/564 (89 %), 19 gaps (3 %)), Myrmecridium banksiae (GenBank NR_111762.1; Identities = 480/553 (87 %), 15 gaps (2 %)) and Myrmecridium spartii (GenBank KX306762.1; Identities = 483/558 (87 %), 17 gaps (3 %)).

Notes — Dactylaria (De Hoog 1985) is heterogeneous (Crous et al. 2016a, 2017b), with its type species, D. purpurella, clustering in Magnaporthales (Klaubauf et al. 2014). Xenodactylaria is reminiscent of Dactylaria and Cylindrosympodium, but distinct in that all structures are hyaline, and conidia occur in short chains. Phylogenetically, it also clusters on its own, and a new genus and family is introduced to accommodate it. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Fusarium robustum (GenBank MH861018.1; Identities = 454/548 (83 %), 37 gaps (6 %)), Fusarium venenatum (GenBank NR_156290.1; Identities = 454/550 (83 %), 38 gaps (6 %)) and Fusarium sambucinum (GenBank KM231813.1; Identities = 451/547 (82 %), 37 gaps (6 %)).

On PDA surface luteous with patches of orange, reverse amber. On OA surface luteous with diffuse amber pigment. Notes — Neomyrmecridium asiaticum represents a new species isolated from dead vines in Thailand, where it cooccurred with another new species, N. septatum. Neomyrmecridium septatum (conidia (1–)3-septate, (12 –)14 –16(– 20) × (3.5–)4(–5) µm) is similar to N. asiaticum based on its conidium morphology, but the two species are phylogenetically distinct. The ITS sequences of N. septatum and N. asiaticum are 89 % (501/560 including 14 gaps) similar. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Neomyrmecridium sorbicola (GenBank MH107901.1; Identities = 510/562 (91 %), 11 gaps (1 %)), Myrmecridium phragmitis (GenBank NR_137782.1; Identities = 489/558 (88 %), 13 gaps (2 %)) and Ramichloridium schulzeri (GenBank MH859088.1; Identities = 481/552 (87 %), 13 gaps (2 %)).

Etymology. A fungus with star-shaped conidia, named for Stella Carnegie, the star of the Carnegie family. Classiﬁcation — Chaetothyriaceae, Chaetothyriales, Eurotiomycetes. Conidiomata sporodochial, slimy, solitary, erumpent, 100 – 200 µm diam, with dark brown, erect, flexuous, aseptate setae that are thick-walled, up to 90 µm long, 3 – 5 µm diam. Mycelium consisting of pale brown, smooth, septate, branched hyphae, prominently constricted at septa, 2 – 3.5 µm diam, with several cells becoming swollen and ellipsoid, 4 –7 µm diam. Conidiogenous cells integrated on hyphae, terminal and lateral, subcylindrical, hyaline, smooth, 8 – 20 × 3 – 3.5 µm, mono- to polyblastic. Conidia variable, solitary, hyaline, smooth-walled, starshaped, with 3 – 4 upright arms and one basal arm attached to the conidiogenous cell; lateral arms 1– 3-septate, constricted at septa, ends obtusely rounded, arms 20–40 × 3–5 µm; basal arm 0(–1)-septate, subcylindrical, 10 – 30 × 3– 5 µm. Culture characteristics — Colonies erumpent, spreading, with sparse aerial mycelium and feathery, lobate margin, reaching 7 mm diam after 2 wk at 25 °C. On MEA, PDA and OA surface and reverse fuscous black. Typus. auStraLia, New South Wales, Kangaroo River State Forest, on leaves of Eucalyptus sp. (Myrtaceae), 23 Jan. 2010, A.J.

Notes — When this fungus was initially observed on host material, it had sporodochia with brown setae, giving rise to star-shaped conidia. In culture, it formed sporodochia, but very few brown setae were observed. Morphologically, it is reminiscent of Vonarxia, having sporodochia with dispersed brown setae, and star-shaped conidia (Crous et al. 2009), but it is phylogenetically distinct, and based on its aseptate setae, we choose to place it in Fumagopsis, a genus presently known from two species, F. complexa (on Eugenia jambolana, India; conidial lateral arms 55–70 × 2–2.8 µm; Wu & Sutton 1995) and F. triglifioides (on Lucuma neriifolia, Argentina; conidial lateral arms (12 –)20 – 24 × 2 – 2.5 µm; Van der Aa & Van Oorschot 1985). Although the three species are distinct based on their conidium morphology, there are presently no molecular data to compare them with F. stellatae.

Conidiomata solitary, erumpent, pycnidial, globose, brown, 200–250 µm diam, exuding a creamy conidial mass; wall of 6–8 layers of brown textura angularis. On OA paraphyses observed among conidiophores, hyaline, smooth, septate, hyphae-like, 2 – 3 µm diam. On OA conidiomata are surrounded by chains of chlamydospore-like cells, prominently constricted at septa, hyaline to brown, 0–1-septate, up to 8 µm diam. Conidiophores lining the inner cavity, subcylindrical, 15–25 × 4–5 µm, smooth, hyaline, giving rise to 1–2 conidiogenous cells.

Conidia solitary, hyaline, smooth, guttulate, aseptate, fusoid, apex subobtuse, base truncate, 2 – 2.5 µm diam, (10 –)13 –15(–17) × (3.5–)4 µm. Culture characteristics — Colonies erumpent, spreading, surface folded, with moderate aerial mycelium and smooth, lobate margin, reaching 15 mm diam after 2 wk at 25 °C. On MEA, PDA and OA surface dirty white, reverse buff to isabelline. Notes — The monotypic genus Fusculina was established for a fusicoccum-like genus occurring on leaf spots of Eucalyptus (Summerell et al. 2006). Fusculina eucalyptorum is distinct from F. eucalypti (conidia 16 – 22 × 3 – 4 µm) by having smaller conidia, and lacking secondary conidia and chlamydospores.

Notes — The genus Neodevriesia (Quaedvlieg et al. 2014) which presently includes approximately 20 species, is discussed elsewhere in this paper. Neodevriesia metrosideri is phylogenetically distinct from all species in the genus. An interesting aspect of this species is the prominent difference between young and mature conidia, where young conidial chains are slender and pale olivaceous, and older chains are wider, prominently constricted at septa, and darker brown.

Notes — The Phaeomoniella generic complex is commonly associated with brown wood streaking (Crous & Gams 2000, Halleen et al. 2007). Taxa in this complex have a hyphomycetous and yeast morph, with a coelomycetous synasexual morph. Neophaeomoniella (based on N. eucalypti) is a genus closely related to Phaeomoniella (Crous et al. 2015b), which has three species, isolated as endophytes from leaves and pine needles. Neophaeomoniella corymbiae was isolated from thyrothecial ascomata on leaves, although the sexual link is unconﬁrmed. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Neophaeomoniella eucalypti (GenBank NR_138001.1; Identities = 581/607 (96 %), 9 gaps (1 %)), Neophaeomoniella niveniae (as Phaeomoniella niveniae, GenBank JQ044435.1; Identities = 550/579 (95 %), 10 gaps (1 %)) and Neophaeomoniella zymoides (GenBank KR909194.1; Identities = 568/601 (95 %), 9 gaps (1 %)).

Etymology. Referring to the substrate from which the fungus was recovered (soil). Classiﬁcation — Cunninghamellaceae, Mucorales, Mucoromycotina. Hyphae hyaline to brownish, coenocytic, smooth- and thickwalled, 5 –12.5 mm wide, with a septum at the branching site, usually ﬁlled with orange oil droplets and presenting more or less abundant solitary or catenulate ovoid swellings, 7.5 –12.5 mm wide. Stolons hyaline to brownish, 5 –14 mm wide. Rhizoids well developed, hyaline, originating along the stolon but never in the same place where sporangiophores arise. Sporangiophores hyaline to brownish, erect to slightly curved, smooth- and thick-walled, 25 – 215 × 2.5 – 5 mm, with a single septum below the sporangium and occasionally with an extra septum at the base when sporangiophores are short, arising along and terminally on the stolons and never grouped in whorls, swellings occasionally seen. Sporangia hyaline to brownish due to the mass of sporangiospores, pyriform, multispored, smooth-walled, apophysate, 17.5 – 27.5 × 17.5 – 22.5 mm. Apophysis funnel-shaped, smooth-walled, 12.5 –17.5 × 7.5 –12.5 mm. Columellae globose, smooth-walled, showing a short collarette, sometimes with a wall projection, 5 –7.5 mm diam. Sporangiospores hyaline when solitary, brownish in mass when mature, smooth-walled, cylindrical, 4–5 × 2–4 mm. Chlamydospores absent. Zygospores not observed.

The closest hits using the LSU sequence was A. cylindrospora var. cylindrospora (GenBank JN206588.1; Identities 620/657 (94 %), 5 gaps (0 %)). In a similar search using the CBS database (Crous et al. 2004), the closest hits using the LSU sequence of the isolate FMR 14989 were A. spinosa var. spinosa (CBS 106.08, Identities 308/406 (75.68 %), 9 gaps (2.2 %)), and A. repens (FSU 939, Identities 543/575 (94.43 %), 1 gap (0 %)). While using the ITS sequence the closest hits were A. cylindrospora var. cylindrospora (CBS 100.08, Identities 470/548 (86 %), 18 gaps (3 %)), and A. pseudocylindrospora (CBS 100.62, Identities 236/262 (90 %), 10 gaps (3 %)). Our phylogenetic tree, built using the LSU sequences, corroborated that our fungus represents a new species of the genus Absidia, A. cylindrospora var. cylindrospora being phylogenetically the most closely related species. Absidia terrestris differs from A. cylindrospora var. cylindrospora in its lower growth rate on MEA at 25 °C and in the absence of growth at 30 °C (A. cylindrospora var. cylindrospora grows up to 34 °C), the sporangiophores not arranged in whorls, the absence of chlamydospores and the presence of both apical and basal septa in the shorter sporangiophores.

Cap 40 – 65 mm diam, planoconvex, obtusely umbonate, light brownish grey; surface glabrous, almost dry, ingrown-ﬁbrillose under lens; margin very distinctly sulcate up to 5 mm with paler context showing between ribs. Lamellae subcrowded, off-white with light yellow-brown ﬁmbriate edge concolorous with stipe apex, ventricose up to ± 7 mm, free. Universal veil fragments absent or present as a few small scattered greyish patches and warts. Stipe 70 – 90 × 10 –17 mm, tapering upwards, with a broad rounded base but not bulbous; context white, ﬁrm, ﬁstulose; surface light grey-brown and pruinose near apex, with paler zebroid ﬁbrils below, in the lower third bearing fragments of volval material. Volva friable, up to 2 mm thick, brownish grey, appearing as wart-like floccules appressed to the stipe surface or partially or completely remaining bound to the substrate. Pileipellis: suprapellis an ixocutis of thin, ﬁlamentous hyaline hyphae in a gelatinous matrix; subpellis hyphae with yellow-grey intracellular pigment, some slightly constricted at septa, some forked, (2.9 –)3.2 –7.2(– 8) µm (av. 5.4 µm) thick; vascular hyphae not plentiful, irregular, aseptate, present in all layers, 2 –12 µm thick. Lamella trama bilateral. Mediostratum of well-inflated elements, ﬁlamentous hyphae scarce. Lateral stratum of inflated intercalary elements, appearing pseudoparenchymatous near lamellar base, closer to margin becoming mostly broadly ellipsoid and broadly fusiform, some branched and irregular-shaped, solitary and in chains of 2 or 3. Subhymenium near lamellar base virtually pseudoparenchymatous, of thin-walled, well-inflated elements, transitioning into the similarly well-inflated mediostratum; closer to the edge more structured, appearing as 2 or 3 layers of inflated, subglobose, angular or irregular (‘jigsaw-puzzle’-like) elements. Vascular hyphae in lamella trama overall very rare, but common in the subhymenial layer of the lamella margin, where they sometimes form tangled masses of branching ﬁlamentous hyphae 2.5 – 3.2 (– 3.5) µm wide. Inflated elements on the lamella margin sphaeropedunculate, some utriform to broadly clavate, some slightly thick-walled, with pale greyish yellow intracellular pigment, 21.2 – 54.3 × 14.1– 32.5 µm (av. L = 31.6, W = 22.0). Universal veil differentiated; outer layer dominated by sphaerocysts, some slightly collapsed, often in chains of 3 or 4, and often with pale yellowish grey intracellular pigment, linked by very thin, thin-walled, often collapsed, branching and forked ﬁlamentous hyphae; ﬁlamentous hyphae more abundant in the inner layer.

The closest and most similar species is the European A. friabilis, mycorrhizal with Alnus in wetland habitats (Tulloss 2018). Amanita paludosa differs from A. friabilis by sparser and less fragmented velar remnants on pileus surface and stipe base due to its more differentiated veil structure with more abundant ﬁlamentous elements; markedly rounder, subglobose spores; mycorrhizal association with Betula; and a known distribution limited to West Siberia. Despite the proximity of the two taxa on molecular level, the signiﬁcant differences in morphology, ecology, and distribution validate separating A. paludosa as a new species.

MB828262). Notes — Calonectria hemileiae is a new member of the C. candelabra species complex (Alfenas et al. 2015, Lombard et al. 2015a, Lopes et al. 2018) based both on morphological characteristics and phylogenetic inference. The morphology of C. hemileiae is similar to that of C. zuluensis and C. polizzii. Nevertheless, it is clearly distinct from those taxa both in terms of ecological niche (the sole species of Calonectria recorded as a mycoparasite) and phylogenetically. Species of the C. candelabra complex are found worldwide, occurring on a range of plant hosts. Morphologically, they are characterised by having ellipsoidal to obpyriform vesicles, and 1-septate macroconidia (Schoch et al. 1999, Crous 2002, Lombard et al. 2010).

Oliveira, R.J. Ferreira, B.D.B. Silva, M.P. Martín & Baseia, sp. nov. Etymology. Referring to the biome in which it was collected. Classiﬁcation — Agaricaceae, Agaricales, Agaricomycetes. Basidiomata growing solitary, 35 – 40 mm wide × 45 – 58 mm high, pyriform to turbinate. Exoperidium slightly tomentose, evanescent, greyish brown (7E3, Kornerup & Wanscher 1978), at the base with sand encrusted at maturity. Mesoperidium membranaceous, smooth, greyish yellow to brown (4B4 to 5F5) at maturity. Endoperidium papyraceous externally, persistent in the basal portion, olive brown to brown (4E3 to 5E4). Gleba initially compact and white to yellowish white (4A1 to 4A2), becoming lanose and powdery, brownish grey to dark brown (5D2 to 9F4) at maturity. Subgleba well-developed, occupying two thirds of the basidioma, when mature pale yellow at base to dark brown going up (4A3 to 6F8), and presenting a different colour band, yellowish white (4A2) at the apex of subgleba. Rhizomorphs densely encrusted with sand, 2.5 – 6.2 µm diam, regular walls ≤ 1.3 µm thick, curved, branched, septate, hyaline in 5 % KOH, and dextrinoid. Exoperidium composed for hyphae, 2.7– 4.5 µm diam, with regular walls ≤ 0.7 µm thick, straight, rarely branched and septate, hyaline in 5 % KOH and not dextrinoid. Endoperidium with hyphae 2.8 – 5.1 µm diam, with regular walls ≤ 1.16 µm thick, straight, branched, frequently septate, pale brown in 5 % KOH, and dextrinoid; presence of mycosclereids globose, subglobose, pyriform, triangular, ovoid, ellipsoid or rectangular shape, present in the apical portion, 14.4 – 29.5 × 7.6 –17.8 µm, with regular walls ≤ 1.35 thick, and straight. Subgleba with hyphae measuring 2.3 – 4.2 µm diam, with regular walls ≤ 1.2 µm thick, curved, branched, septate, hyaline in 5 % KOH, and dextrinoid. Paracapillitium absent. Capillitium Calvatia-type, hyphae 2.7–4.5 µm diam with regular walls ≤ 0.88 µm thick, straight, frequently branched, septate, with small and numerous circular pits, hyaline in 5 % KOH, dextrinoid. Basidiospores subglobose, equinulated, 5.4 –7.4 × 5.1– 6.7 µm [χ = 5.9 ± 0.5 × 5.6 ± 0.4; Qm = 1.06; n = 20], pedicels present in some spores, ≤ 1.09 µm, hyaline in 5 % KOH, dextrinoid and acyanophilic. Habit & Habitat — Growing solitary or two basidiomata on decaying leaves. characters, it is closely related to some other Calvatia species, such as C. crucibulum, C. cyathiformis, C. fragilis and C. lilacina. Calvatia fragilis has a lycoperdon-type capillitium with numerous small circular pits; however, C. fragilis does not have a subgleba or it is reduced, and basidiospores are smaller and ﬁnely equinulated (Morgan 1890, Silveira 1943). Calvatia crucibulum, a species reported only by Kreisel (1992, 1994), has similar morphological characteristics, such as a capillitium with small and numerous pits, woolly gleba, and ﬁne exoperidium. However, in those publications the author does not describe some macroscopic (subgleba) and microscopic structures (basidiospores), which makes a comparison difﬁcult. In the present study these two species are well separated by their ITS nrDNA barcode sequences. Calvatia lilacina is another morphologically similar species to C. caatinguensis, mainly based on the distinct colour band at the apex of the subgleba; however, C. lilacina has smaller basidiospores (3 – 5 μm), which are verrucose to spinulose (Bottomley 1948). In recent decades, C. fragilis and C. lilacina have been considered by some researchers as synonyms of C. cyathiformis (Bottomley 1948, Zeller & Smith 1964, Liu 1984, Moyersoen & Demoulin 1996, Poumarat 2003, Wartchow & Silva 2007), while others have considered C. lilacina as a synonym of C. fragilis (Kreisel 1992, 1994). Calvatia cyathiformis is recognised by the violaceous gleba, pulverulent, verrucose to echinate basidiospores, subgleba cellular and well developed, capillitium long, branched and with numerous circular pits (Dissing & Lange 1962, Zeller & Smith 1964). This species has been reported in several parts of the world (Morgan 1890, Dissing & Lange 1962, Zeller & Smith 1964, Liu 1984, Moyersoen & Demoulin 1996, Poumarat 2003), including Brazil (Silveira 1943, Viégas 1945, Wartchow & Silva 2007). Calvatia cyathiformis is characterised by a marked morphological variation in basidiospores and capillitium. However, C. caatinguensis has a distinct colour band at the apex of the subgleba, in addition to a marked encrustation at the basal exoperidium when mature, not observed in C. cyathiformis. Morphological and molecular data (ITS nrDNA) provide strong support for C. caatinguensis as a distinct species of Calvatia. Typus.

Sm. & S. Cruz, gen. nov. Etymology. The genus name Carolinigaster refers to North Carolina, the region where this truffle was collected, and ‘gaster’ (Greek for ‘stomach’) in reference to the fact that the spores of this truffle species are enclosed inside of the fruiting body. Classiﬁcation — Boletaceae, Boletales, Agaricomycetes. Distinguished from other Boletaceae by a combination of the following characters: Basidiomata hypogeous to partially emergent, sequestrate, globose to subglobose. Peridium not changing colour when handled. Gleba loculate. Lacking a stipe or columella. Basidiospores statismosporic, globose to subglobose, ornamented with short irregular warts at maturity, pink in water and inamyloid but strongly dextrinoid, bleaching to almost hyaline in KOH.

Basidiomata hypogeous, globose to subglobose, 0.5 – 2 cm diam, attached to the substrate by ﬁne white rhizomorphs. Peridium bright white to pinkish white, completely enclosing the gleba when young but thinning and wearing away with age, not changing colour when handled or bruised. Gleba loculate, locules up to 0.5 mm diam but mostly 0.25 mm or smaller, light pink when young but becoming pinkish brown to light brown in mature specimens, rubbery when fresh. Lacking a columella or sterile base. Odour indistinct, taste not recorded. Peridium 50 – 210 µm thick, hyaline, comprised of loosely interwoven gelatinised hyphae mostly 5 µm diam, notably softer in 3 % KOH than in water or Melzer’s, with occasional incorporated rhizomorphs up to 10 µm diam and slightly dextrinoid. Basidia 40 – 55 × 10 –15 µm but narrowing to 5 µm at the base, fourspored, clavate to subcapitate and scattered. Sterigmata mostly 5 – 6.5 µm long and 0.5 –1 µm diam. Trama tissues appearing gelatinised, especially when mounted in KOH. Basidioles numerous, hyaline, clavate or occasionally subcapitate, 30 – 45 × 8 –13 µm wide, narrowing to 3.5 – 4.5 µm at the base. Clamp connections not observed. Cystidia not observed. Basidiospores statismosporic, 8.8 –11 × 5.9 – 8.4 µm (av. 9.7 × 7.3 µm), Q = 1.2–1.8 (mean Q = 1.35), globose to subglobose, pink in water, inamyloid and strongly dextrinoid in Melzer’s reagent, bleaching to almost hyaline in KOH, spore wall mostly 1 µm, ornamented with triangular to rounded warts that are 0.5 –1.5 µm tall × 1– 2 µm wide at the base, with a hyaline perispore that is always visible in young spores but is more difﬁcult to see in mature spores, often with a visible hilar appendage that is approximately 0.5 µm diam and 1– 2 µm long. Habitat & Distribution — Fruiting in the soil beneath the leaf litter in mixed forests dominated primarily by Quercus, Fagus and Pinus on silty-clay soil. Known only from Durham County but likely present at appropriate sites across North Carolina’s Piedmont region. Additional specimen examined. uSa, North Carolina, Durham County, Durham, Eno River State Park, c. 200 m a.s.l., in mixed pine and hardwood forest, hypogeous in soil below the leaf litter, 16 Oct. 2009, M.E.

Mixed Fagaceae-dominated forest near in Durham, North Carolina where Carolinigaster bonitoi was collected; section of hyaline trama viewed in Melzer’s reagent (scale bar = 25 µm), basidiospores showing strong dextrinoid responses when viewed in Melzer’s reagent (scale bar = 10 µm), fresh basidiomata (scale bar = 1 cm). All photos are of the holotype MES331 (FLAS-F-62017). Notes — Carolinigaster bonitoi is unique in having a hypogeous sequestrate fruiting habit, a bright white peridium that does not stain when handled or bruised, and a loculate gleba without a columella or sterile base that is light pink when young but becomes pinkish brown to brown at maturity. It has lightly ornamented spores covered by a perisporium. The spores are pinkish in water and strongly dextrinoid in Melzer’s reagent but bleach almost completely hyaline in 3 % KOH. Carolinigaster bonitoi is related to species of Austroboletus, Fistulinella, Veloporphyrellus and Mucilopilus in the Austroboletoideae. Mucilopilus castaneiceps forms a sister clade to C. bonitoi but without support. Mucilopilus castaneiceps is a Japanese epigeous bolete that is superﬁcially quite different from C. bonitoi but it actually shares some important features. Both taxa have dextrinoid spores, both have hymenial surfaces that are light when young but become dark pink or pinkish brown at maturity, and both fruit in association with trees in the Fagaceae (Takahashi 1988). The only other known truffle in the Austroboletoideae is Solioccasus polychromus (Trappe et al. 2013, Wu et al. 2016). Solioccasus polychromus is a brightly coloured tropical associate of Myrtaceae and Fabaceae that has smooth ellipsoid spores and is known only from Australasia. No other bolete truffle has all of the same morphological features as C. bonitoi but the most similar taxon is Jimtrappea guyanensis (Smith et al. 2015). However, J. guyanensis is phylogenetically distant and has large, amyloid hymenial cystidia and smooth fusoid spores that are not dextrinoid, and is restricted to Dicymbe-dominated forests in Guyana. Carolinigaster bonitoi is thus far known only from two collections from mixed, Fagaceae-dominated forests in North Carolina, USA. It is interesting that this species has not been found previously, particularly since Coker & Couch (1928) extensively studied the gasteromycetes (including hypogeous sequestrate species) of North Carolina. Coker & Couch (1928) recognized 26 species of ‘Hymenogasteraceae’ in their book but none of the species they studied are similar to C. bonitoi. For supplementary information see MycoBank. Matthew E.

Ferreira & R.W. Barreto, sp. nov. Etymology. Referring to the host, Solanum betaceum, from which it was described. Classiﬁcation — Mycosphaerellaceae, Capnodiales, Dothideomycetes. Lesion on living leaves, starting as small necrotic dots, becoming sub-circular, to irregular, 5 –15 mm diam, brown, with dark brown margins, coalescing and leading to extensive blight. Internal mycelium indistinct. Stromata reduced to few angular cells, 12–25 × 35–55 μm. Conidiophores predominantly hypophyllous, rarely epiphyllous, in fascicles of 5–22 conidiophores, sub-cylindrical, geniculate, 100 –172 × 4 – 5 μm, 3 –7-septate, unbranched, pale olivaceous brown, smooth. Conidiogenous cells terminal, subcylindrical, sympodial, sub-hyaline, 15 – 65 × 3 – 5 μm. Conidiogenous loci conspicuous, 2 – 3 μm diam, strongly thickened, darkened. Conidia obclavate to subcylindrical, straight to slightly curved, 47–130 × 3–5 μm, apex rounded to subacute, base truncate, 3 –12-septate, guttulate, hyaline, smooth. Culture characteristics — Slow-growing (45 mm in PDA and 35 mm in PCA, after 15 d) at 25 °C. Colony sub-umbonate, edge entire, aerial mycelium dense and felty, white; in PDA radially sulcate. Reverse rosy buff with concentric haloes olivaceous. Sporulation absent. Notes — A Cercospora sp. has been reported on Cyphomandra betacea (= S. betaceum) in Malawi (Peregrine & Siddiqi 1972) and Zimbabwe (Whiteside 1966). Other records of Cercospora spp. on members of Solanum spp. are: Cercospora apii, C. canescens, C. cyperacearum, C. lanugiflori, C. physalidis, C. puyana, C. solanacea, C. solani, C. solanicola, C. solanigena (Farr & Rossman 2018). The morphology of the Cercospora on tree tomato was similar to that of species belonging to the C. apii complex (Groenewald et al. 2013). A BLASTn search on GenBank indicated a considerable similarity of C. solani-betacei to other species belonging to Cercospora. A concatenated phylogenetic tree was constructed with ITS, cmdA and actA and, the combined result clearly supported S. betaceum as a distinct species. Koch’s postulates were performed and the pathogenicity of the fungus to S. betaceum was demonstrated. Typus.

This species was discovered during a Citizen Science project in the Netherlands, ‘Wereldfaam, een schimmel met je eigen naam’, describing novel fungal species isolated from Dutch soils. Classiﬁcation — Microascaceae, Microascales, Sordariomycetes. Colonies on OA at 25 °C attaining 18–24 mm in 14 d, ochreous to buff coloured, flat, membranous with regular margins. On PDA at 25 °C attaining 13–15 mm in 14 d, white to light buff, flat, fluffy to dusty with membranous periphery and regular margins. Vegetative hyphae septate, hyaline, smooth- and thin-walled. Conidiophores mononematous, penicillate branched; irregularly bi- to terverticillate, bearing groups of 2–4 conidiogenous cells, rarely reduced to single conidiogenous cells borne laterally on the aerial hyphae, hyaline to subhyaline, smooth-walled. Conidiogenous cells percurrent, lageniform to ampulliform, (11–)13.5 – 29(– 44) × 3 – 4.5 μm, 21.4 ± 7.5 × 3.9 ± 0.3 μm long, broad at the widest part, tapering to a long cylindrical, annellated zone, 1.5 – 2.5 μm wide, up to 23 μm long, annellations inconspicuous. Conidia bullet-shaped or broadly clavate, (5.5 –)6.5 –10.5(–13) × (2.5 –)3 – 4(– 5), 8.6 ± 1.7 × 3.5 ± 0.4 μm, with a distinctive truncate base and rounded or slightly pointed apex, subhyaline to pale brown in mass, smooth- or ﬁnely roughened, thick-walled, arranged in long chains. Notes — The genus Acaulium was recently reinstated and segregated from Scopulariopsis (Sandoval-Denis et al. 2016). Four species are currently accepted (Woudenberg et al. 2017). Acaulium pannemaniae closely resembles Acaulium album. However, the new species differ by producing mononematous conidiophores only in contrast to the synnematous conidiophores of A. album. Acaulium pannemamiae also exhibits much larger conidiogenous cells, often with exceptionally long annellated necks which also contrast with all other known species of the genus.

This species was discovered during a Citizen Science project in the Netherlands, ‘Wereldfaam, een schimmel met je eigen naam’, describing novel fungal species isolated from Dutch soils. Classiﬁcation — Plectosphaerellaceae, Glomerellales, Sordariomycetes. Mycelium consisting of branched, septate, smooth, hyaline and thin-walled hyphae, up to 2 μm wide. Conidiophores simple or poorly branched, hyaline, smooth-walled, up to 83 µm long. Phialides lateral or terminal, subcylindrical to subulate, hyaline, smooth, 17– 46 × 1.5 – 2 µm, with minute cylindrical collarette and periclinal thickening at the conidiogenous locus. Conidia cylindrical or ellipsoidal, sometimes with a slightly truncate base, 1-celled, hyaline, thin- and smooth-walled, 3.5 – 6 × 1.5 – 2 µm, arranged in slimy heads. Chlamydospores lateral or intercalary, single, with or without intermittent hyaline cells, subglobose or clavate, brown, smooth- and thick-walled, 4 –7 × 3.5– 5.5 μm. Culture characteristics — Colonies on OA and PDA after 10 d at c. 25 °C, reaching 25–27 and 28–29 mm diam, respectively, flat, surface and reverse dark mouse grey to fuscous black, with a pale mouse grey mycelium forming concentric rings. Notes — Gibellulopsis species are commonly soil-borne fungi, morphologically characterised by sparse branched conidiophores, ellipsoidal to cylindrical conidia and olive-brown chlamydospores (Domsch et al. 2007). Batista & Maia (1959) introduced the genus based on G. piscis, which was subsequently synonymised with Verticillium nigrescens (Zare et al. 2007). The genus was recently revised, and ﬁve species were accepted. Gibellulopsis chrysanthemy (Hirooka et al. 2014) was segregated from Gibellulopsis and accommodated elsewhere (Giraldo & Crous 2019). Morphologically, G. simonii resembles G. nigrescens in having lateral or intercalary subglobose chlamydospores. Gibellulopsis simonii, however, produces shorter and less branched conidiophores than those of G. nigrescens (up to 100 μm long), and is phylogenetically different from the ex-type strain of that species.

Lombard & Hern.-Restr., sp. nov. Etymology. From Latin septimana- meaning week, fini- meaning the end of, and scientiae- meaning science. Named after the ‘Weekend of Science’. Classiﬁcation — Nectriaceae, Hypocreales, Sordariomycetes. Conidiophores initially as lateral phialides arising directly from somatic hyphae, simple or rarely branched, monochasial or verticillate, straight, hyaline, smooth-walled, aseptate or with basal septum, up to 32 µm long. Conidiogenous cells monophialidic or rarely polyphialidic, arising laterally from hyphae or in terminal pairs, or verticils of three, cylindrical to subulate, 6 –16 × 3–4 µm, thin- and smooth-walled, hyaline with inconspicuous collarettes and periclinal thickening. Macroconidia falcate, more or less straight, slightly narrowing towards the ends, apical cell often hooked with a more or less pointed tip, basal cell slightly pedicellate, (1–)3-septate, (19 –)25 – 29(– 34) × 3 – 4 µm (av. 27 × 3 µm), hyaline, thin- and smooth-walled. Microconidia absent. Chlamydospores single or in pairs, intercalary or terminal, globose to obovoid, thick-walled and verruculose. Sexual morph unknown. Culture characteristics — Colonies on OA, MEA and PDA at 25 °C attaining 25 – 30 mm in 7 d. On OA aerial mycelium absent with slimy appearance due to abundant sporulation on medium surface, buff to primrose, margin entire. On MEA aerial mycelium absent with slimy appearance due to abundant sporulation on medium surface, rosy buff to buff, reverse buff, margin entire. On PDA aerial mycelium absent with slimy appearance due to abundant sporulation on medium surface, pale luteous to buff, reverse pale luteous, margin entire. Typus. the netherLandS, Utrecht Science Park, Westerdijk Fungal Biodiversity Institute, from soil in front of the bronze statue of Johanna Westerdijk, Mar. 2017, M. Hernandez-Restrepo (holotype CBS H-23749, culture ex-type CBS 144935); ITS, LSU, tef1 and tub2 sequences GenBank MK069422, MK069418, MK077808 and MK069408, MycoBank MB828215). Notes — Fusarium s.lat. has recently been segregated into several fusarium-like genera, one of which is Fusicolla (Lombard et al. 2015b, Guarnaccia et al. 2018). Fusicolla septimanifiniscientiae can be distinguished from other species in the genus Fusicolla by the formation of polyphialidic conidiogenous cells on the somatic hyphae (Gräfenhan et al. 2011). Based on phylogenetic inference of the ITS sequences, F. septimanifiniscientiae is closely related to F. aquaeductuum, F. matuoi and F. merismoides. However, F. septimanifiniscientiae mostly produced 3-septate macroconidia ((19–)25–29(–34) × 3–4 µm (av. 27 × 3 µm)), rarely 1-septate, which are smaller than the 3-septate macroconidia of F. aquaeductuum (30–55 × 2.5–3.5 µm; Gerlach & Nirenberg 1982), F. matuoi ((25 –)33 – 56 × (1.5 –)2 – 3 µm; Hosoya & Tubaki 2004) and F. merismoides (26 – 48 × 3– 4.3 µm; Gerlach & Nirenberg 1982).

Lombard, sp. nov. Etymology. Named for Tjidde Hilhorst, who collected the sample. This species was discovered during a Citizen Science project in the Netherlands, ‘Wereldfaam, een schimmel met je eigen naam’, describing novel fungal species isolated from Dutch soils. Classiﬁcation — Bionectriaceae, Hypocreales, Sordariomycetes. Colonies on OA at 25 °C attaining 12 – 20 mm in 7 d, aerial mycelium collapsed with abundant sporulation on the medium surface forming vinaceous green to vinaceous black droplets of conidial masses, margin undulate surrounded by a vinaceous to greyish rose halo, surface vinaceous black, reverse isabelline in the centre becoming vinaceous towards the margins. On MEA at 25 °C attaining 20 – 25 mm in 7 d, with moderate aerial mycelium, felty with string folds into the medium, margin undulate, surface olivaceous black in the centre due to abundant sporulation becoming brick to rosy vinaceous towards the margin, surrounded by a vinaceous halo, reverse vinaceous to rosy buff. Sexual morph not seen. Vegetative hyphae septate, hyaline, smooth- and thin-walled, becoming slightly verrucose with age, 1– 2.5 µm wide. Conidiophores erect, arising directly from vegetative hyphae, simple or branched, straight, hyaline and smooth-walled becoming slightly verrucose and subhyaline with age, aseptate or with basal septum, up to 56 µm long. Conidiogenous cells phialidic, arising laterally from hyphae or in terminal pairs, or verticils of three, or small monopodially branched tufts of up to four from conidiophores, monophialidic, aseptate, elongate-ampulliform to subcylindrical, 13 – 24 µm long, 1– 3 µm wide at the base, thin- and smooth-walled to slightly verrucose, hyaline to subhyaline with inconspicuous collarettes and periclinal thickening. Conidia unicellular, ovoid to broadly ellipsoidal, 3 – 5 × 2 – 3 µm (av. 4 × 2 µm), subhyaline to olivaceous green, thick- and smooth-walled, forming slimy heads on the phialides. Chlamydospores not seen. Notes — Lasionectria hilhorstii is morphologically reminiscent of Acremonium cereale (Gams 1971), but can be distinguished by the lack of flared collarettes and basal swelling of the phialides.

Etymology. rintelii, refers to the name of the collector of the ex-type strain, Marinus Rintel. This species was discovered during a Citizen Science project in the Netherlands, ‘Wereldfaam, een schimmel met je eigen naam’, describing novel fungal species isolated from Dutch soils. Classiﬁcation — Muyocopronaceae, Muyocopronales, Dothideomycetes. Mycelium hyaline to pale brown composed of smooth-walled, septate, 1– 2 µm wide hyphae. Conidiophores micro- to semimicronematous composed of one to many globose to irregular cells, thin-walled, hyaline, smooth. Conidiogenous cells monoor polyblastic, lateral or terminal, subcylindrical, globose or irregular, non-denticulate, hyaline, smooth, 3.5 – 6.5 × 3.5 – 5 µm. Conidia solitary, cylindrical, rounded at both ends or truncate base, hyaline, 1-septate, smooth, multi-guttulate, 8 –14.5 × 3 – 4 µm, with a simple, ﬁlamentous subterminal appendage at each end, 2.5 – 6 μm long. Chlamydospores not observed. Culture characteristics — Colonies on OA and CMA after 1 wk at 25 °C, aerial mycelium lacking except in the centre, where occasionally white tufts are observed, pale ochreous to cinnamon with age, reverse concolourous. Notes — Leptodiscella is an uncommon genus known mainly from soil (Papendorf 1967, Matsushima 1975, Madrid et al. 2012) and dust (Udagawa & Toyazaki 1985). Leptodiscella rintelii is more similar to L. africana in having hyaline, 1-septate conidia and lacking chlamydospores (Papendorf 1967). However, L. rintelii can be distinguished from L. africana by having shorter and wider conidia with shorter appendages (11–17.5 × 2 – 3 µm, 6.5–13 µm long, in L. africana, Papendorf 1975). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence are L. brevicatenata (GenBank FR821312.1; Identities = 485/455 (96 %), 7 gaps (1 %)), L. chlamydospora (GenBank FR745398.1; Identities = 449/489 (92 %), 12 gaps (2 %)) and L. africana (GenBank NR_145359.1; Identities = 457/509 (90 %), 14 gaps (2 %)).

This species was discovered during a Citizen Science project in the Netherlands, ‘Wereldfaam, een schimmel met je eigen naam’, describing novel fungal species isolated from Dutch soils. Colonies on OA at 25 °C attaining 45 – 55 mm in 7 d, salmon due to abundant sporulation on medium surface giving a wet and slimy appearance, effuse, with edge entire surrounded by a light cyan blue halo; reverse salmon. On MEA at 25 °C attaining 38 – 50 mm in 7 d, rosy buff, effuse, with strong folds into the medium with edge entire; reverse rosy buff. Vegetative hyphae septate, hyaline, smooth- and thin-walled, 1–2.5 µm wide. Conidiophores erect, arising directly from vegetative hyphae, simple or rarely branched, straight, hyaline, smooth-walled, aseptate or with basal septum, up to 75 µm long. Conidiogenous cells phialidic, arising laterally from hyphae or in terminal pairs, or verticils of three, or small monopodially branched tufts of up to four from conidiophores, monophialidic, aseptate, elongateampulliform to subcylindrical, 13 – 27 µm long, 1– 3 µm wide at the base, thin- and smooth-walled, hyaline with inconspicuous collarettes and periclinal thickening. Conidia unicellular, ellipsoidal, bacilliform to fusiform, sometimes slightly curved, 3–5 × 1– 2 µm (av. 4 × 2 µm), hyaline, thin- and smooth-walled, forming slimy heads on the phialides. Chlamydospores not seen. Notes — The genus Parasarocladium was recently introduced by Summerbell et al. (2018) and included three species, P. breve, P. gamsii and P. radiatum. Conidia of P. debruynii (3–5 × 1– 2 µm) are smooth-walled compared to the chromophilic roughened conidia of P. breve (Gams 1971) and smaller than those of P. gamsii ((4 –)5 –7(–12) × 0.5 –1 µm; Tichelaar 1972). Furthermore, the phialides of P. debruynii lack any septation, distinguishing it from P. radiatum (Gams 1971). Additionally, ribosomal DNA sequences resolved P. debruynii as a distinct lineage within the genus Parasarocladium.

Etymology. boutwelliae, refers to the name of the collector of the ex-type strain, Katrina Boutwell. This species was discovered during a Citizen Science project in the Netherlands, ‘Wereldfaam, een schimmel met je eigen naam’, describing novel fungal species isolated from Dutch soils. Classiﬁcation — Conioscyphaceae, Conioscyphales, Sordariomycetes. Description on OA. Mycelium composed of septate, hyaline, smooth, 1– 2.5(– 4) µm wide hyphae. Conidiophores reduced to conidiogenous cells. Conidiogenous cells monoblastic, cupulate, endogenous, multilayer cup-like collarette after several percurrent enteroblastic tiny elongations, hyaline, smooth, 11.5 – 20.5 × 8–15 µm. Conidia solitary, unicellular, ellipsoidal, obovoid or subglobose, base truncate with a central pore of 1–1.5 μm diam, brown, pitted-wall, 10.5 – 21 × 8–13.5 µm. Culture characteristics — Colonies on OA after 1 wk at 25 °C, flat, spreading with scarce aerial mycelium, powdery, shiny, black, margin effuse. Notes — Conioscypha includes 13 species mainly isolated as saprobes from submerged dead wood and leaves (Matsushima 1975, 1993, 1996, Shearer 1973, Crous et al. 2014a, Zelski et al. 2015, Chuaseeharonnachai et al. 2017, HernándezRestrepo et al. 2017). Conioscypha boutwelliae is the ﬁrst species described from soil, besides C. varia that has been reported from agricultural soil according to the CBS database. Conioscypha boutwelliae is similar to C. japonica, C. lignicola and C. pleiomorpha in having dark brown pitted conidia. However, they differ in shape and size, while in C. boutwelliae conidia are wider (8 –13.5 μm) than in C. japonica (4.5 –10 μm) and C. pleiomorpha (6 – 9 μm), they are narrower than in C. lignicola (11–12 μm).

This species was discovered during a Citizen Science project in the Netherlands, ‘Wereldfaam, een schimmel met je eigen naam’, describing novel fungal species isolated from Dutch soils. Classiﬁcation — Sarocladiaceae, Hypocreales, Sordariomycetes. Colonies on OA at 25 °C attaining 27– 32 mm in 14 d, pale saffron to rosy buff, effuse, glabrous with undulate to lobate margin. On PDA at 25 °C attaining 38 – 43 mm in 14 d, saffron to salmon, effuse, glabrous, with edge entire. Vegetative hyphae septate, hyaline, smooth- and thin-walled, 1– 2.5 µm wide. Conidiophores erect, arising directly from vegetative hyphae or from ropes of hyphae, simple or rarely branched, straight, hyaline, smooth-walled, up to 35 µm long. Phialides subcylindrical, 17– 24 µm long, 1– 2 µm wide at the base, thin- and smooth-walled, hyaline with inconspicuous periclinal thickening; adelophialides and schizophialides not observed. Conidia unicellular, cylindrical, ellipsoidal, ovoid to irregular, 3–5 × 1– 2 µm (av. 3 × 1.5 µm), hyaline, thin- and smooth-walled, arranged in slimy heads. Chlamydospores rare, intercalarily, smooth-walled, 5 µm diam. Notes — Sarocladium dejongii is morphologically similar to several species characterised by producing conidia in slimy heads (Giraldo et al. 2015). However, this species is distinguished from all these species by the multiple conidial shapes produced and the formation of intercalary chlamydospores. Additionally, ribosomal DNA sequences resolved S. dejongiae as a distinct lineage within the genus Sarocladium.

Culture characteristics — Colonies on PDA after 14 d at c. 25 °C, reaching 22 – 23 mm diam, elevated, slightly folded, salmon, with brown punctiform sporodochia on the top. Notes — Lectera was introduced based on the plant pathogen Lectera colletotrichoides as the type species, along with L. longa (Cannon et al. 2012). Recently, three more species have been added to the genus, i.e., Lectera capsica from Capsicum annuum, L. phaseola from Phaseolus vulgaris and L. humicola from soil (Crous et al. 2017a, Giraldo & Crous, in prep.). Morphologically, L. nordwiniana resembles L. longa and L. phaseola in the profuse production of flexuous setae in artiﬁcial media. However, in L. nordwiniana these structures are longer (up to 193 μm long) than those produced by the other species (L. longa up to 111 μm long, L. phaseola up to 38 μm long).

Immature basidiomata subglobose, 13–18 × 16–22 mm, greyish white (12A1–12B1 KW) with a single and thick rhizomorph greyish white (12A1–12B1 KW). Expanded basidiomata obovate to subglobose 46–95 × 24–71 mm. Arm meshes pentagonal to hexagonal, rugose at the beginning of development, becoming smooth afterwards, 32–90 × 20–70 mm, dull red to pinkish white (8B3–8A2), transverse section of an arm shows 3–4 tubes subglobose, elongated to piriform. Pseudostipe absent. Gleba mucilaginous, in all inner part of arms, olive brown (KW 4F4), with an unpleasant smell. Volva 50–140 × 10–40 mm, greyish white (12A1–12B1 KW), with thick rhizomorph, greyish white (12A1–12B1 KW). Basidiospores cylindrical, 4.6–5.6 × 1.9–2.7 µm (5.2 ± 0.4 × 2.3 ± 0.3 µm; Qm = 2.29; n = 30 spores), wall ≤ 0.7 µm, smooth, hyaline in KOH. Arms exhibiting subglobose to globose and pyriform cells, 19.5–45.6 × 13–33.5 µm, wall ≤ 2.2 µm diam, hyaline. Volva composed of ﬁlamentous hyphae, 2.7–5.2 µm diam, wall ≤ 1.1 µm diam.

Medeiros (holotype UFRN-Fungos 2948, isotype UFRN-Fungos 2947, paratype UFRN-Fungos 2946, ITS and LSU sequences GenBank MH107232 and MH107235, MycoBank MB824737). tubes in transverse section. This species presents similarities with Clathrus cristatus with the colour of the arms and mesh arrangement, but that presents basidiomata with crests along the arm edges (Fazolino et al. 2010), a characteristic absent in C. natalensis. In a BLASTn search, the ITS sequence obtained in this study has 94 % similarity to Clathrus ruber (GenBank GQ981501). However, C. ruber can easily be distinguished by the bright red colour, smaller meshes, and the immature basidiome marked by reticulations (Dring 1980). In the phylogenetic analysis, C. natalensis does not group with any species available on GenBank; in fact, they are clearly morphologically different. Clathrus columnatus and C. archeri show distinct receptacle arrangements, columnar in the ﬁrst, and united arms below with pointed tips initially attached in the latter (Bosc 1811, Dring 1980); C. crysomycelinus and C. delicatus have white basidiomata, the ﬁrst differs by a glebifer attached at the junction of the arms, and the second by a smaller receptacle (up to 25 mm high × 15 mm wide) and deep grooves in the outer face of the arms (Möller 1895, Dring 1980) – characteristics absent in C. natalensis. Thus, both morphological characters and the phylogenetic analysis separate C. natalensis from the already known species.

Typus. chiLe, Los Ángeles, on leaves of Fuchsia magellanica (Onagraceae), 11 July 2012, J. Jure (holotype RGM 2481, culture ex-type SAG 53350-12 = CBS 144795; ITS, LSU, GAPDH, ACT and TUB2 sequences GenBank MH817944, MK014743, MH817950, MH817956 and MH817962, MycoBank MB827627, TreeBASE Submission ID 23265). For additional material examined, see MycoBank. Notes — Colletotrichum arboricola was isolated for the ﬁrst time on leaves of Fuchsia magellanica, but its presence has since been observed in different arboreal hosts in the central area of Chile. A phylogenetic analysis based on sequence data from four loci (ITS, GAPDH, ACT and TUB2) places the fungus in clade 5 of the Colletotrichum acutatum complex (Damm et al. 2012). Colletotrichum arboricola is separated from other species by GAPDH and ACT, with GAPDH performing best as a diagnostic sequence. The closest matches in a BLASTn searches with the GAPDH sequence were C. phormii CBS 118194 (GenBank JQ948777; Identities = 245/252 (97 %), no gaps), C. acerbum CBS 128530 (GenBank JQ948790; Identities = 242/252 (96 %), no gaps) and C. johnstonii CBS 128532 (GenBank JQ948775; Identities = 241/252 (96 %), no gaps). Due to size and shape overlapping of conidia, appressoria and ascospores with others members of the complex, C. arboricola is not reliably distinguishable using morphological characteristics. One of the two equally most parsimonious trees (67 steps, CI = 0.896, HI = 0.104, RI = 0.957) obtained from the multilocus phylogenetic analysis (ITS-GAPDH-ACT-TUB2) for selected Colletotrichum species belonging to the C. acutatum complex. The analysis was conducted with PAUP v. 4.0b10 (Swofford 2003). DNA sequences were aligned using MAFFT v. 7.0 employing the E-INS-i strategy. Bootstrap support values ≥ 75 % are shown above nodes (1 000 replicates). The tree was rooted with Colletotrichum orchidophilum. T = ex-type.

Notes — The genus Diaporthe has been extensively reviewed and several new species have been included in it (MarinFelix et al. 2019). BLASTn searches using ITS sequence of Diaporthe poincianellae demonstrated 99 % similarity to D. velutina (GenBank NR_152470.1), amongst others. The LSU sequence is 99 % similar to D. phragmitis (GenBank MH878644.1), amongst others. The CaM sequence has 93 % similarity to D. anacardii (GenBank KC343266.1). The his3 sequence is 94 % similarity to D. inconspicua and D. pseudoinconspicua (e.g., GenBank KC343607.1 and MH122517.1). Based on the tef1 sequence D. poincianellae is 88 % similarity to D. velutina (GenBank KX999178.1), and based on tub2 sequence it is 95 % similar to D. cissampeli (GenBank KX228384.1). Morphologically, D. poincianellae differs from D. velutina based on the size of pycnidia (69 – 428 μm diam), conidiophores (10 – 23 × 1– 2.5 μm), alpha conidia sometimes clavate (5.5–10 × 2–2.5 μm) and by the presence of beta conidia (Gao et al. 2017). Furthermore, D. poincianellae also differs from D. cissampeli by the size of its pycnidia (up to 200 μm diam), conidiogenous cells phialidic (10 –15 × 1– 2 μm) and alpha conidia subcylindrical (7.5 –12 × 2 – 3 μm) (Crous et al. 2016b).

Morozova, Noordel., Brandrud & Krisai, sp. nov. Etymology. The epithet refers to the habitat of the species in broad-leaved forests. Classiﬁcation — Entolomataceae, Agaricales, Agaricomycetes. Basidiomata medium-sized, collybioid to tricholomatoid. Pileus 11‒ 50 mm diam, initially hemispherical to convex with or without a small acute umbo, becoming applanate with central depression, with involute then straight margin, hygrophanous, translucently striate at margin when expanded, quickly pallescent on drying, when moist initially pale brownish grey to ochraceous grey, becoming paler, whitish grey (3B3–4, 4B3–4, 4C3 – 4, 5B3 – 4, 6D5 – 6, Kornerup & Wanscher 1978), often almost white when dry (4A2), surface dry, smooth, glabrous, sometimes with a few scattered, white hairs at margin (when young and fresh). Lamellae moderately distant (L = 30 – 40, l = 1– 3), adnexed, adnate-emarginate or adnate with small tooth, arcuate-segmentiform, narrow, whitish, pale grey, becoming pinkish or orange-white (5A2, 6A2), with entire, concolorous edge. Stipe 30 – 80 × 3 –7 mm, cylindrical or fusiform, base rarely broadened, sometimes tapering towards base, white, greyish pale to watery grey, longitudinally ﬁbrillose striate, base distinctly hairy. Context greyish beige, hygrophanous, solid then hollow. Smell nitrous or somewhat soap-like, or with a sweetish, perfume-component, somewhat farinaceous. Spores (7–)8 – 9.5(–12) × (5.5 –)6 – 8(– 9) μm, Q = (1–)1.2–1.3(–1.5), subisodiametrical, with 5–7 angles in side-view. Basidia 28–45 × 8 –11 μm, 4-spored, narrowly clavate to clavate. Cheilocystidia absent. Hymenophoral trama regular, made up of inflated elements, 55 –130 × 6 –13 μm. Pileipellis a cutis of parallel, cylindrical hyphae, 3 –7 μm wide, with slender clavate terminal elements up to 12 μm wide, these a bit uplifted; subpellis welldifferentiated, made up of inflated elements, 40 –100 × 8 – 28 μm. Pileitrama regular, made up of inflated elements, 45 –120 × 20 – 35 μm. Pigment intracellular and sometimes with additionally incrusted thin hyphae of pileipellis. Clamp-connections abundant in all structures. Habit, Habitat & Distribution — In groups on soil in broadleaved forests, mainly under Carpinus, Quercus, Fagus or Tilia. Known from Austria, Estonia, Hungary, Norway, Russian Caucasus, and Iran (from root samples). lucently striate pileus, a relatively fragile white stipe, isodiametrical or subisodiametrical spores, and a nitrous (to soap-like) smell. The smell of the species in the E. rhodopolium-E. nidorosum group is rather variable, and perceived differently by different mycologist, but it is deﬁnitely different from the pure and often strong farinaceous smell and taste found in other rhodopolioid Entoloma species. Diagnostic features of E. silvae-frondosae are pale basidiomata with distinctly hairy stipe base, and occurrence in temperate broad-leaved forests with Carpinus, Fagus and Tilia. Similar species within the E. rhodopolium clade, such as E. melenosmum (= E. nidorosum, Kokkonen 2015), E. nidorosum and E. politum, have another ecology, preferring moist to swampy Betula and Salix forests. In addition, they usually have darker basidiomata. However, E. rhodopolium s.str. often grows in similar habitat as E. silvae-frondosae like Corylus and Fagus forests in boreonemoral-temperate regions (Kokkonen 2015, Brandrud et al. 2018). Although E. rhodopolium s.str. has on average somewhat darker, larger basidiomata with less distinct hairy stipe base, it might sometimes be difﬁcult to distinguish it morphologically from E. silvae-frondosae.

Morozova, Dima, Bendiksen & Noordel., sp. nov. Etymology. The epithet refers to the occurrence of the species with Tilia spp., in calcareous Tilia forests and parks with Tilia. Classiﬁcation — Entolomataceae, Agaricales, Agaricomycetes. Basidiomata medium-sized, tricholomatoid. Pileus 20 ‒ 60 mm diam, initially hemispherical-campanulate to convex-umbonate, becoming applanate with or without a low and broad central umbo, with slightly involute then straight margin, typically strongly hygrophanous, in exposed habitats often only seen in dried up state, and then rather pale brownish grey, in shadow rich places in water-soaked state starting off rather dark greyish brown to greyish brown (6F4–6, 7F3–6, Kornerup & Wanscher 1978), sometimes almost black at centre or the entire pileus when young, pallescent when drying up to pale brownish but small or expanded, thin-fleshed basidiomata can be much paler when dry grey (5D4 – 6, 5E4 – 6 up to 5C3 – 4); surface dry, glabrous, smooth or slightly rugose in the centre, initially sometimes ﬁnely white-silvery ﬁbrillose-pruinose at centre, not striate when young, only weakly striate at margin when mature. Lamellae moderately distant (L = 30 – 40, l = 3– 5), adnexed, adnate-emarginate or adnate with small decurrent tooth, whitish to pale greyish, becoming pinkish or greyish pink (7A2–3), with entire, concolorous edge. Stipe 30–70 × 3–11 mm, cylindrical or slightly fusiform, base sometimes tapered, sometimes distinctly clavate-bulbous (up to 1 cm broad) longitudinally ﬁbrillose striate due to whitish ﬁbrils on more or less greyish background, with age or when dry whitish; basal mycelium sparse, white, cottony, sometimes with white rhizomorphs; sometimes with reddish spots at the stipe base (also in context). Context greyish in the stipe and under the pileus surface, usually whitish in the inner part of the pileus, when dry whitish in most of context. Smell and taste farinaceous. Spores (8 –)9 – 9.5(–11.5) × (6.5–)7–7.5(–9) µm, Q = (1–)1.2–1.3(–1.4), subisodiametrical, with 6 –7 angles in side-view. Basidia 38 – 48 × 11–12.5 µm, 4-spored, narrowly clavate to clavate, clamped.

Typus. ruSSia, Saint Petersburg, Botanical Garden of the Komarov Botanical Institute RAS, N59.968889° E30.320833°, under Tilia × europaea, 19 Aug. 2011, O. Morozova (holotype LE254179, ITS and LSU sequences GenBank MH790420 and MH792063, MycoBank MB827527), as E. gerriae in Morozova et al. (2014). For additional material examined, see MycoBank. Notes — Entoloma tiliae is characterised by an usually uniformly dark-coloured pileus, longitudinally ﬁbrillose striate rather rigid greyish stipe, isodiametrical or subisodiametrical spores, intracellular and additionally minutely incrusting pigments and a farinaceous smell. The majority of collections also exhibit some reddish spots/stains at bulb base on a few specimens. According to our phylogeny, the species belongs to a well-supported clade including, e.g., E. rubrobasis and E. griseorugulosum (Brandrud et al. 2018). In our phylogram, the species comes out as a sister to E. griseorugulosum and E. rivulare. Entoloma griseorugulosum has a resembling morphology and ecology, but it is distinguished on the rugulose pileus surface and habitat in the Quercus and Castanea forests. Furthermore, reddish stains at the base of the stipe is never noted on E. griseorugulosum. The recently described E. rivulare (Kokkonen 2015) is a small, boreal species, associated with wet habitats with Alnus or Populus. Entoloma rubrobasis (also demonstrating reddish tinge in the stipe base) and E. boreale are so far found only in Fennoscandian boreal coniferous forests, probably associated mainly with Betula and Picea, respectively (Kokkonen 2015, Brandrud et al. 2018). Entoloma griseoluridum is another deciduous forest species described with somewhat similar features, but we have not been able to sequence the type of this species. According to the protologue (Kühner in Kühner & Romagnesi 1954), E. griseoluridum, however, lacks incrusting pigment on the narrow hyphae of pileipellis, it is more robust species with purplish red tinge in pileus, has dark lamellae, and it grows in Quercus, Fagus, Carpinus forests. Ludwig (2007) considered E. griseopruinatum and E. griseoluridum synonymous. Entoloma gerriae, also a very dark species from a similar habitat, differs by the more slender and tender basidiomata, coarsely incrusting and very dark intracellular pigment, and its holotype sequence nests in a distinct, rather distant clade. Some specimens of Entoloma tiliae previously were erroneously interpreted as Entoloma griseoluridum (e.g., in Zhukova et al. 2017), another deciduous forest species described with somewhat similar features. Unfortunately, we have not been able to sequence the type of this species. See tree on Fungal Planet 839.

Pham, Y.C. Li & O.V. Morozova, sp. nov. Etymology. The epithet refers to the white and olivaceous colours of the basidiomata. Classiﬁcation — Boletaceae, Boletales, Agaricomycetes. Basidiomata small to medium sized, boletoid. Pileus 15 ‒ 50 mm diam, hemispherical to convex or subapplanate; with dark olivaceous grey (4D3 – 4, 4E3 – 5, 5D3 – 5E3, Kornerup & Wanscher 1978), greyish beige (4C3 – 4) to dark green, greyish green or olive green (28E8, 28C3 – 5, 30E7– 8) scales and flakes over white background, becoming when mature grass green to yellowish green (30E7, 29B5 – 6), embedded in the gelatinous matter, more closely spaced in centre; slimy to viscid, in wet condition; margin almost lacking scales, white, overhanging the hymenophore, entire, slightly inrolled when young. Hymenophore tubular, adnate-emarginate to shortly decurrent with tooth to the stipe, 3 – 8 mm thick, whitish to creme (4A1– 3), unchanging in colour when bruised, pinkish from spores in maturity; pores rounded to angular, 1– 2 /mm, with fringed edge; tubes concolorous with the hymenophore surface.

Zeng 416, FHMU 202, tef1α sequence GenBank MH746439. Notes — The genus Fistulinella was originally described based on a species from Cameroon (Hennings 1901). It is characterised by the whitish to pink tubular hymenophore, the pinkish to brownish pink spore print, the smooth, elongate to fusiform, more or less dextrinoid basidiospores, and the presence of gelatinised structures in the pilei- and stipitipellis (Wu et al. 2014). Fistulinella olivaceoalba ﬁts these characteristics rather well. It is recognised by the small slimy basidiomata with distinct greenish or olivaceous colours in the pileus and pinkish hymenophore. Microscopically long cylindrical septate cheilo- and caulocystidia, as well as fusiform pleurocystidia are also characteristic. Based on these features it is close to F. cinereoalba (Fulgenzi et al. 2010), which, however, lacks greenish colours in basidiomata and grows in South America. In GenBank this species is represented by the ITS sequence, which is signiﬁcantly different from that of F. olivaceoalba. There are no sequences of the type species, Fistulinella staudtii, available. But according to a 3-gene (tef1α, rpb2, LSU) phylogeny (Wu et al. 2014), a specimen from China (HKAS 53367) is grouping together with Fistulinella prunicolor, and belongs to the subfamily Austroboletoideae. However, they are rather distant – p-distance = 12.6 % difference of tef1α sequences. The genus Fistulinella appears to be polyphyletic and needs additional examination. A BLASTn search of the ITS sequence of LE312004 in GenBank shows 99 –100 % similarity with sequences obtained in the course of environment studies in Japan (e.g., GenBank LC315825 – ectomycorrhiza of Pinus amamiana, GenBank AB807905 – ectomycorrhiza of Quercus, and also GenBank AB973727 and AB509575).

Lima, J.O. Sousa, M.P. Martín & Baseia, sp. nov. Etymology. Name refers to ‘Piquiri-Una’ environmental preservation area in Rio Grande do Norte State, Brazil, where the type specimen was collected, around a community at the margins of Catu River. In Tupi-Guarani indigenous language, piquiri means ‘river with little ﬁshes’; una means black, dark. Classiﬁcation — Geastraceae, Geastrales, Agaricomycetes. Immature basidiomata epigeous, orange-yellow (N10Y80M30; Küppers 2002), subglobose, 3 mm high × 3 mm wide, rounded apex, surface not encrusted, hirsute, short hairs (< 0.5 mm high), presence of subicular base with rhizomorphs (up to 15 mm long), encrusted with debris. Expanded basidiomata saccate, 3.5 – 6 mm high (including peristome) × 10 –18 mm wide.

Endoperidium greyish brown (N60Y60M40), globose to subglobose, 2 – 5 mm high (including peristome) × 3– 7 mm wide, sessile, glabrous. Peristome ﬁnely ﬁbrillose, delimited by a yellowish pale brown (N10Y20M10) annulum, lighter than endoperidium, mammiform (< 1 mm high), 1.9 – 2.3 mm wide. Gleba powdery, darkened grey (N99Y00M00). Eucapillitium brownish, 2.9–5.6 µm wide, not branched, surface encrusted, verrucose, lumen non-evident, tapering towards the end, thin walls (< 1 µm thick). Basidiospores subglobose, 4.7– 6.3 µm diam (av. = 5.5 ± 0.4 × 5.3 ± 0.4 µm, Qm = 1.03, n = 30), brownish in 5 % KOH, slightly flattened, conspicuous ornamentation at light microscopy, composed of confluent warts (0.2 – 0.5 µm high) with truncate apex, and irregularly distributed under SEM.

Geastrum pusillipilosum, BraZiL, Paraíba, Mamanguape, REBIO Guaribas, SEMA II, 26 June 2014, J.O. Sousa JM100 (holotype UFRN-Fungos 2315, ITS and LSU sequences GenBank KX761175 and KX761176). Notes — Geastrum piquiriunense is mainly characterised by its small basidiomata (up to 18 mm wide), hirsute mycelial layer, presence of a subicular base with rhizomorphs, delimited peristome, and subglobose basidiospores 4.7– 6.3 µm, slightly flattened, with irregular confluent warts with truncate apex. This species is morphologically similar to G. pusillipilosum regarding its small size, hirsute mycelial layer, and delimited ﬁbrillose peristome. Geastrum pusillipilosum can be recognised by its slightly larger, globose basidiospores (5 – 6.8 µm, Qm = 1.0), covered by longer columnar warts (0.6–2 μm high; Crous et al. 2016a), and also by rhizomorphs covered by irregular oblique prism crystals, 2.5– 2.8 × 4.8 – 8.6 μm. Geastrum schweinitzii and G. pleosporum also have small size basidiomata (up to 20 mm wide) and delimited peristome; however, G. schweinitzii has well-developed subiculum, caespitose growth, and smaller basidiospores (up to 5 μm diam) (Sousa et al. 2014), while G. pleosporum is characterised by smooth to subsmooth irregular shaped basidiospores up to 5 μm diam (Douanla-Meli et al. 2005). Geastrum piquiriunense could be also confused with G. hirsutum, but the latter can be distinguished by having longer and strigose mycelial tufts (up to 3 mm long) at its mycelial layer, and quite smaller basidiospores (2.5 – 3 μm wide) (Baseia & Calonge 2006, Silva et al. 2015). In our phylogenetic analysis G. piquiriunense grouped tightly with GenBank JN845120 (TENN:061141, MLbs = 99 %, PP = 1, MPbs = 100 %); nonetheless, this sequence is identiﬁed as G. saccatum both at the online database of University of Tennessee (TENN Herbarium) and the GenBank database, while in Kasuya et al. (2012), the same code (JN845120 –TENN:061141) is identiﬁed as G. sessile (= G. fimbriatum, according to Index Fungorum). The hirsute mycelial layer clearly distinguishes G. piquiriunense from G. saccatum or G. sessile (= fimbriatum); moreover, these two species have predominantly smooth, sometimes felted or wrinkled mycelial layers (Sunhede 1989). In addition, G. sessile has an endoperidium with protruding hyphae and smaller basidiospores (2.7– 5.2 μm diam) (Leite & Baseia 2007, Alfredo et al. 2016); also G. saccatum has smaller basidiospores (3.6 – 4.5 μm diam) (Leite et al. 2011). Thus, our analysis conﬁrms a misidentiﬁcation of collection TENN:061141, since it is not included in the clades of the sections Corollina nor Fimbriata; this collection needs to be morphologically reassessed in order to determine if it belongs to G. piquiriunense, or even if it is a new species awaiting description.

Typus. ecuador, Esmeraldas province, Chocó Tropical Rainforest, alt. 357 m, July 2012, A. Salazar (holotype QCAM 3123, Fungarium QCAM, ITS-LSU sequence GenBank MH890527, MycoBank MB827824, TreeBASE Submission ID 23292). Notes — Morphologically, the sample belongs to the G. applanatum complex (Gottlieb & Wright 1999). The Neotropical Polypores key (Ryvarden 2004) indicates G. australe as the closest species. However, there are some morphological discrepancies, such as the shape and uniform thickness of the cuticle across the basidiocarp, the thickness of the tubes, the homogeneous context, lack of resin deposits, and the trimitic hyphal system in G. chocoense. Phylogenetically, G. chocoense is distinct from all taxa presently known to occur in the genus, with the closest species from the megablast search using the full ITS sequence being G. podocarpense (GenBank MF796661; 100 % Query Coverage, Identities = 544/568 (96 %), 11 gaps (1 %)). Ganoderma podocarpense was ﬁrst described as a new species from Ecuador in 2017 (Crous et al. 2017b). Subsequent megablast hits are of Ganoderma species from Argentina and Brazil. The ITS phylogenetic tree of the top 10 megablast hits for the G. chocoense holotype sequence substantiates that it is a new species. The phylogenetic tree was constructed using the Maximum Likelihood plugin PHYML in Geneious R9 (http://www.geneious. com; Kearse et al. 2012), and the substitution model determined by jModelTest 2.1.10 (Guindon & Gascuel 2003, Darriba et al. 2012) according to the Corrected Akaike Information Criterion (AICc). Ganoderma sp. (GenBank AF255195) represents the outgroup. Bootstrap support values > 80 % are given above branches. The phylogenetic position of G. chocoense is indicated in bold. The species name is followed by the GenBank accession number, and when the country of origin was indicated, the three letter United Nations country code, in order of appearance, is used, namely TWN: Taiwan, VNM: Vietnam, THA: Thailand, CHN: China, NZL: New Zealand, ECU: Ecuador, BRA: Brazil, and ARG: Argentina.

Etymology. From Greek ξερός-, dry, and Latin -tolerans, tolerance, due to the ability of this fungus to grow on culture media with a low water activity. Classiﬁcation — Incertae sedis, Hypocreales, Sordariomycetes. Mycelium composed of hyaline, septate, funiculose hyphae, 2–3 μm wide. Conidiophores borne on vegetative mycelium, determinate, erect, septate, penicillate, bi- to terverticillate, mostly solitary, sometimes funiculose; stipes hyaline, 25 –155 × 2–3 μm, septate, smooth-walled to verrucose, asymmetrically branched; primary branch (= rami) cylindrical, 20 – 40 × 2–3 μm, mostly septate, smooth-walled to verrucose; terminal branch (= metulae) cylindrical, 7–15 × 2 μm, rarely 1-septate, with smooth to verrucose walls, in whorls of 2 – 3; phialides cylindrical, 8 –10 × 1.5 – 2 μm, abruptly tapering at the apex, with smooth to verrucose walls, in whorls of 2 – 5. Conidia hyaline, aseptate, ellipsoid to ovoid, 3 – 4 × 1.5 – 2 μm, rounded at both ends, smooth-walled, disposed in chains of up to 20 conidia. Sexual morph not observed. Culture characteristics — Colonies on MEA reaching 38–39 mm diam after 2 wk at 25 °C, slightly elevated, powdery, margins irregular, orange white (5A2; Kornerup & Wanscher 1978) at centre and white (5A1) at edge, exudates absent, sporulation abundant; reverse orange (6A6), diffusible pigment absent. Colonies on CYA reaching 49–51 mm diam after 2 wk at 25 °C, slightly elevated, powdery, margins regular, white (4A1) at centre and pale yellow (4A3) at edge, exudates absent, sporulation abundant; reverse reddish orange (7B7) at centre and pale orange (6A5) at edge, diffusible pigment absent. Colonies on CZD 62 – 63 mm diam after 2 wk at 25 °C, cottony, margins irregular, white (3A1), exudates absent, sporulation abundant; reverse yellowish white (3A2), diffusible pigment absent. Colonies on YES reaching 62 – 63 mm diam after 2 wk at 25 °C, slightly elevated with radial waves, reddish grey (12B2) and white (4A1), exudates absent, sporulation abundant; reverse reddish brown (9E7) at centre and orange (6A6) at edge, diffusible pigment absent. This fungus grows on culture media with a low water activity (on DG18 after 2 wk at 25 °C, 10 –12 mm diam; on G25N in the same conditions, 27– 29 mm diam; on MY70S, 39 – 40 mm diam; and on MEA with 30, 40 and 50 % (glucose 50 % / fructose 50 %), 23 – 24 mm diam, 18 –19 mm diam and 12 –13 mm diam, respectively). In these culture media the fungal sporulation is abundant. Minimum, optimal and maximum temperature of growth: 15 °C, 25 °C and 35 °C, respectively. Typus. SPain, Tarragona province, Els Pallaresos, isolated from a darkened wall of a house, 19 Apr. 2018, J. Cano & A.M. Stchigel (holotype CBS H-23734, cultures ex-type FMR 17085 = CBS 144969; BenA, EF1-α, ITS and LSU sequences GenBank LS998791, LS998792, LS998789 and LS998790; MycoBank MB827825). Notes — Geosmithia xerotolerans was recovered from the surface of a darkened house wall taken in Els Pallaresos, Tarragona province, Spain. The genus Geosmithia was erected to accommodate species previously placed in Penicillium, with the following differentiable combination of characters: colonies in colours other than greyish blue or greyish green, penicillate and roughened conidiophores, with both phialides and conidia cylindrical (Pitt 1979). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hit using the ITS sequence is the ex-type strain of Geosmithia cnesini MK 1820 (GenBank AM947671; Identities = 965 / 978 (99 %), 1 gap (0 %)); using the LSU sequence it was Geosmithia microcorthyli CCF3861 (GenBank MG954241; Identities = 809/815 (99 %), no gaps); using the EF1-α sequence, it was Geosmithia omnicola CNR8 (GenBank KR135476; Identities = 238/280 (85 %), 13 gaps (4 %)); and using the BenA sequence it matched with Geosmithia omnicola CNR43 (GenBank KP990575; Identities = 429/460 (93 %), 9 gaps (1 %)). Our ITS-BenA-EF-α phylogenetic tree corroborated the placement of our isolate as a new species of Geosmithia, being phylogenetically close to Geosmithia omnicola.

Soares & Ryvarden, sp. nov. Etymology. (L.) resupinata, bent, referring to the shape of the basidiomata. Classiﬁcation — Meripilaceae, Polyporales, Agaricomycetes. Basidiomata annual, resupinate, 2 – 4 cm wide and long and 1 mm thick, adnate, fleshy and white when fresh (2B) becoming distinct rusty red when bruised after collecting, hard and fragile and black when dry (black 37) (Watling 1969), pores irregular, about 1–2 mm in the sloping substrate, in other parts of the holotype more regular and 4 – 5 pores per mm, tubes concolorous with the pore surface. Context almost absent, dense and black when dry (37). Hyphal system monomitic; generative hyphae with simple septa, hyaline to pale yellow, thin-walled, 3 – 6 µm wide. Gloeoplerous hyphae and cystidia absent. Basidia not seen. Basidiospores 4 – 5 µm diam, globose to subglobose, smooth, thin-walled, IKI-. Typus. BraZiL, Amapá, Porto Grande, Serra da Capivara, on dead wood, 2014, A. Soares 2014-49 (holotype URM, isotype O, ITS and LSU sequences GenBank MG255826, MycoBank MB823555). Colour illustrations. Environment where the type specimen was collected in Porto Grande, Serra da Capivara, Amapá, Brazil; Henningsia resupinata fresh basidiomata (top), dried basidioma, generative hyphae and basidiospores (bottom). Scale bars = 2 cm (basidiomata), 20 µm (generative hyphae), 10 µm (basidiospores). Notes — The black basidiomata when dry, the simple septate hyphae and the globose to subglobose basidiospores clearly place this species in Henningsia where all species share the same colour and simple septate generative hyphae. Henningsia resupinata can be separated from the other species of the genus by the resupinate basidiomata. Henningsia macrospora is another species also found in Brazil and also has a black basidioma when dry, but it is separated by the pileate basidiomata with numerous gloeoplerous hyphae in the context and the larger, subglobose to ellipsoid basidiospores (6 –7 × 4.5 – 5 µm) (Gibertoni & Ryvarden 2014). In the phylogenetic tree, H. resupinata clustered with low support with Physisporinus sp. (47 %/0.68) collected in Indonesia and it is distantly related to P. sanguinolentus (KHL_11913) collected in Norway. Physisporinus sanguinolentus is similar by the white basidiomata when fresh and becoming bright rusty red when bruised or greyish to blackish on drying. However, the pores in P. sanguinolentus are smaller (8 –10 per mm) and the basidiospores are larger and ovoid to subglobose (6 –7 × 5 – 6 µm). Besides, P. sanguinolentus has fusoid cystidioles (15 – 27 × 5 – 6 µm) which are lacking in the new species (Ryvarden & Gilbertson 1994). There is no molecular data regarding Henningsia, and, for the time being, the new species will be kept in this genus due its morphological characters. Moreover, Henningsia is a Neotropical genus and the type species is from Brazil, while Physisporinus occurs mostly in Europe. Maximum likelihood phylogenetic tree inferred from ITS+LSU sequences performed with RAxML v. 7.0.4 (Stamatakis 2006). Bayesian analysis (BY) was performed with MrBayes v. 3.2.1 software (Ronquist et al. 2012) for 5 M generations with four Markov chains, and trees sampled every 1 000 generations, similar topology was obtained (not shown). Bootstrap support values (1 000 replicates) and posterior probabilities (PP) from Bayesian analysis to each node are shown from left to right. The new species described in this study is in bold face.

Etymology. Refers to the colour of the pileus and stipe. Classiﬁcation — Inocybaceae, Agaricales, Agaricomycetes. Pileus up to 40 mm, widely campanulate, then convex to plane, with central umbo, obtuse and irregular proﬁle, with sulcatedcracked margin. Cuticle ﬁbrillose-rimose, slightly chappedsquamulose, more cracked at the centre; colour yellowish to bread crust (Munsell 7.5YR: 8/6, 7/8; 10YR: 7/8; 2.5Y: 7/8), then pinkish, old-pink to orange-fulvous and reddish bronze all over the basidioma (Munsell 2.5YR: 6/8; 5YR: 7/8; 7.5YR: 7/8; 10YR: 7/8). Cortina white, observed in early stages. Lamellae close, thick, colour very light (Munsell 2.5Y: 8/3-4), then ochraceous, olivaceous (Munsell 2.5Y: 7/6) to rust-concolorous (Munsell 2.5Y: 7/8), white floccose edge, crenulated. Stipe 40 – 50 × 3 –7 mm cylindrical, pruinose on the upper part, ﬁrst whitish to straw coloured (Munsell 2.5Y: 8/3-4), then grey to grey-rose pale, concolorous with pileus; covered with coarse, long, and whitish ﬁbrils. Flesh white, ﬁrm, red staining absent, smell absent. Basidiospores (7.5–)8.2–10(–10.7) × (5–)5.3–6.2(–6.6) µm, Q = (1.2–)1.3–1.5(–1.7), smooth, subamygdaliformis, with small soprapicular depression and variable apex, obtuse to subconic and rarely conic-papillate; germinative pore sometimes visible. Basidia 35 – 40 × 9 –12 µm, tetrasporic. Paracystidia not observed. Hymenial cystidia 50–85 × 10–15 µm cylindrical or slightly clavate, clavate-subutriformis, sinuose, subcapitate to capitate, not lageniforme; wall 0.5 –1(– 2) µm thick, without oxalate crystals calcium or rarely present; NH3-. Caulocystidia only in the upper part of the stipe, (1/4), 100 × 10 µm, flexuose, subcylindrical, catenulate. turns to orange-red, concolorous to the external surface (Alessio & Rebaudengo 1980). Because the flesh of I. roseascens does not change colour when damaged, and the absence of smell, it cannot be placed in the section Lactiferae, and it most likely belongs to the supersection Cortinatae (Boursier & Kühner 1928). Species in Cortinatae have a cortina at young states, and a stipe that is slightly pruinose at the apex only, or not at all. Based on our molecular analysis, the closest species to I. roseascens is I. melanopus, a species described from Northern America and well known in Europe (Kuyper 1986, Stangl 1989, Bon 1997, Alpago Novello 2006, Bizio 2012). Inocybe melanopus was ﬁrst described by Stuntz as I. melanopoda (Stuntz 1954), as cited in Index Fungorum. However, it is universally accepted with the orthographic variant I. melanopus. Inocybe melanopus is not a reddening species, with stipe dark brown to blackish, pileic surface lanose feltrate, ochraceous to beige with infrequent cystidia, cylindrical-fusiform, caulocystidia absent. In I. roseascens, the stipe is never blackish. )"$ ( )"$ ( $$$ ( " ## " $ $ $ ! +!, * , # &% $ ##$ ! * $ " " "* Typus. itaLy, Veneto, Agordo, loc.

Notes — Only two Inocybe species with smooth spores, I. whitei and I. godeyi, have both metuloid cystidia and a reddening surface, as in the new species proposed here. The basidiomata of I. roseascens are at ﬁrst yellow-ochre, which gradually turn reddish, but this is not the case in its odourless flesh. Based on a morpho-chromatic point of view, I. roseascens is close to the group of I. withei, because of its partially cystidiate stipe and the absence of basal bulb. Inocybe godeyi has ochre to orange-fulvous-red, brick-pink or rarely red carmine sporocarps, and it belongs to the supersection Marginatae because of its fully cystidiate stipe and marginate basal bulb.

Notes — Analysis of the ITS region of the surveyed yeasts suggested that they were conspeciﬁc and represented a hitherto undescribed species of Kwoniella. Based on NCBIs GenBank database, the best hit using the ITS sequence is K. botswanensis CBS 12716, GenBank NR_119822 (96 %, 10 subst. and 7 gaps), using LSU it is K. dendrophila CBS 6074, GenBank NG_058326 (98 %, 12 subst.), using SSU it is K. mangrovensis CBS 8507, GenBank KF036681 (99 %, 10 subst.), K. shivajii CBS 11374, GenBank KF036652 (99 %, 9 subst. and 1 gap), using TEF1 it is K. dendrophila CBS 6074, GenBank FJ534856 (95 %, 15 subst.), and using RPB1 it is K. dendrophila CBS 6074, GenBank KF036320 (82 %, 147 subst.). In compliance with a recent revision of the genus (Liu et al. 2015), the phylogenetic placement of the new species is demonstrated using the LSU rDNA phylogeny. No growth on L-sorbose, methyl alphaD-glucoside, salicin, citric acid, methanol, YM agar with 10 % NaCl and growth on DL-lactic acid, 50 % w/w glucose / yeast extract (0.5 %) agar are good physiological tests for the distinction of the new species from the phylogenetically closely related species of the genus.

Notes — The genus Lareunionomyces was established by Crous et al. (2016b), with L. syzygii as the type species. Lareunionomyces loeiensis is designated as a new species based on both morphological characteristics and phylogenetic analyses. Lareunionomyces loeiensis is similar to L. syzygii and L. eucalypti, but distinct from them in that it has conidia aggregating in longer chains that form a mucoid spore mass. Conidiophores are longer than those of L. syzygii (50 –100 × 5–8 µm) and similar to those of L. eucalypti (60 –160 × 5 – 6 µm) but up to 3-septate only while other are 2 –7-septate. Conidia of L. loeiensis are slightly wider than those species, the apex and base are truncate, and occur in long chains.

Mill. & Huhndorf, sp. nov. Etymology. The speciﬁc epithet refers to this species resembling a smaller version of L. ovina. Classiﬁcation — Lasiosphaeriaceae, Sordariales, Sordariomycetes. Ascomata ampulliform to ovoid, papillate, 200 – 250 µm diam, 200 – 350 µm high, numerous, scattered to gregarious, superﬁcial; young ascomata tomentose, white, tomentum becoming tightly appressed, crust-like and cream to waxy and brownish grey with age, areolate, ﬁnally tomentum wearing away and ascomata becoming black and glabrous; neck conical, glabrous, black. Ascomatal wall of textura angularis in surface view, in longitudinal section 3-layered, 20 – 40 µm thick, inner layer pseudoparenchymatous, 5–8 µm thick, composed of 3–5 layers of elongate, flattened, pale brown cells, middle layer pseudoparenchymatous, 10 –16 µm thick, composed of 3 – 5 layers of polygonal to angular, pale brown cells, outer layer prosenchymatous, 5 –16 µm thick, composed of several to few layers of hyphae depending on age of ascomata, hyphae 1–2.5 µm wide, hyaline to pale brown, septate, thin-walled. Ascomatal apex with periphyses. Centrum with yellow pigments that quickly diffuse in water. Paraphyses ﬁliform, 2 – 5 µm wide, longer than asci, hyaline, numerous, septate, unbranched, persistent. Asci cylindrical, 85–130 × 8–14 µm, stipitate, stipe 24–46 × 2.5–4.5 µm, numerous, unitunicate, thin-walled, apex truncate; ring narrow, shallow, refractive; subapical globule smooth, 2 – 4 µm wide; with 8 bi- to triseriate ascospores.

Habitat — Decayed wood in a tropical forest. Distribution — Known only from Costa Rica. Typus. coSta rica, San Jose, San Gerardo de Dota, Albergue de Montage, Savergre, Sendero la Quebrada, on 10 cm branch with loose bark, N9.33 W83.48, 701 m elev., 12 May 1996, S.M. Huhndorf & F.A. Fernandez (holotype SMH 2392 (F), isotype at ILLS, ITS-LSU sequence GenBank MH700179, MycoBank MB827965). Notes — Lasiosphaeria miniovina possesses the typical characters known for the genus: tomentose ascomata containing yellow centrum pigments (Miller & Huhndorf 2004a, b). This species can be distinguished by its small whitish ascomata, presence of a distinct ascal subapical globule, and short cylindrical ascospores that lack appendages and produce swollen heads with age. It has ascomata, asci and ascospores resembling L. ovina, but all characters are about half the size as those found in L. ovina. Lasiosphaeria ovina has ascospores with appendages but the ascospores never form a swollen head, whereas L. miniovina has ascospores that lack appendages and that form a swollen head with age. Lasiosphaeria miniovina is only known from Costa Rica, whereas L. ovina occurs widespread throughout north temperate regions, although it has been reported once from Costa Rica (as Lasiosphaeria chrysentera; Miller & Huhndorf 2004b). Lasiosphaeria lanuginosa occurs in Costa Rica and was collected at the same time (GenBank AY587916) as L. miniovina, but it differs in having longer ascospores (33–60 vs 22–33 µm) and ascospores with long, lash-like appendages. 94 Lasiosphaeria ovina AY587929 Lasiosphaeria ovina AY587926 82 Lasiosphaeria lanuginosa AY587916 90 Lasiosphaeria sorbina AY587934 Lasiosphaeria sorbina AY587935 100 95 Lasiosphaeria similisorbina MF806376 Lasiosphaeria similisorbina MF806377 Lasiosphaeria miniovina MH700179 100 Lasiosphaeria glabrata AY587914 Lasiosphaeria glabrata AY587915 Lasiosphaeria rugulosa AY587932 0.02 Lasiosphaeria rugulosa AY587933 Maximum likelihood tree generated using PhyML in Seaview v. 4.5.4 (Gouy et al. 2010).

Notes — Ophiocordyceps houaynhangensis produces ascomata on the subterminal part of the stroma, while the asexual morph is on the apex of the stroma, a feature reminiscent of O. brunneipunctata and O. stylophora. Their hosts are coleopteran larvae that can be found buried in soil. Ophiocordyceps brunneipunctata can be found throughout Thailand (Luangsaard et al. 2008) and Laos (our surveys and observation) while Ophiocordyceps stylophora is a rare species that was reported from North America (South Carolina; Minnessota) and China (Chachuła et al. 2011). Our phylogenetic analyses and morphological assessment support the placement of O. houaynhangensis in Ophiocordycipitaceae (Sung et al. 2007). Based on its micro-morphological characters, O. houaynhangensis more closely resembles O. brunneipunctata in the size of its partspores that range from 4 – 6 × 1–1.5 µm (Hywel-Jones 1995, Evans et al. 2018), while O. stylophora produces whole ascospores, 102 –164 × 2 – 3 µm (Mains 1958). However, O. houaynhangensis differs signiﬁcantly from O. brunneipunctata in the size of perithecia and colour of its stroma as well as in the length of the phialides. In O. houaynhangensis the perithecia are longer than those reported for O. brunneipunctata (270–335 µm long) by Hywel-Jones (1995), and the stromata are pale yellow-brown with brown ostioles. In O. brunneipunctata they are cinnamon coloured, and the phialides are longer (up to 30 µm long) while they are shorter in O. brunneipunctata (up to 23 µm long). The results of our phylogenetic study using LSU and tef1 sequences clearly separates O. houaynhangensis from O. brunneipunctata. For supplementary information see MycoBank.

SPain, Canary Islands, Tenerife, San Miguel de Abona, NE of Costa del Silencio, NNE of Monumento Natural de la Montaña Amarilla, N28°00'59" W16°38'03", 35 m alt., on detached branch of Euphorbia canariensis (Euphorbiaceae), 16 Dec. 2012, L. Quijada & R. Castro (holotype TFC Mic. 23767, ITS-LSU sequence GenBank MH221071, MycoBank MB825108). Notes — Orbilia amarilla was collected on rotten wood of a detached, xeric branch of Euphorbia canariensis in the hyperarid Euphorbia scrubs in the south of Tenerife. In ascospore shape it resembles O. pisciformis (series Commatoideae or Rubellae ined.), which occurs in the same habitat, and O. caudata (series Piliferae ined.). These two species sharply differ, however, in having capitate paraphyses and partly glassy processes. Also, it resembles O. pilifera (series Piliferae), but this latter and O. pisciformis differ in having tear-shaped, narrowly attached spore bodies. A sequence of O. amarilla comprising SSU, ITS and LSU (S1506 intron absent) was obtained by Guy Marson (pers. comm.) from apothecia of the holotype. Orbilia amarilla shows an ITS distance of 7.5 % and LSU (D1– D2) distance of 3 % to O. pilifera, but 20 % (ITS) and 5.5 % (LSU) to O. pisciformis. Our phylogenetical analyses supported the relationships between O. amarilla and O. pilifera in the clade of series Piliferae within sect. Aurantiorubrae of subg. Habrostictis (1.00 BIPP, 100 % ML-BS), see Baral et al. (2017).

Notes — A BLAST search against an ex-type reference sequence dataset (Visagie et al. 2014b), placed the new species in Penicillium sect. Aspergilloides. A multigene phylogeny resolves P. fortuitum as sister to a clade containing P. infra-aurantiacum, P. malmesburiense and P. sublectaticum. Morphologically, it is easily distinguished from these based on its restricted growth on MEA, a character typical of P. brunneoconidiatum, P. tsitsikammaense and P. turcosoconidiatum. However, conidia of P. brunneoconidiatum have thick rough walls and are brown, colonies of P. tsitsikammaense typically produce sclerotia, while conidiophores of P. turcosoconidiatum have very short stipes (Houbraken et al. 2014). -/93 */97 */96 0.99/88 */97 x4 -/80 -/88 0.03 Colour illustrations.

Conidiophores short and monoverticillate (83 % of the cases) and frequently occurring as side branches of the divaricate type of conidiophores, occasionally biverticillate (17 %). Isolated phialides born directly on hyphae occur frequently and mycelial coilings were sometimes observed.

Notes — Penicillium guaibinense morphologically resembles P. curticaule (Visagie et al. 2015) and is phylogenetically more related to P. singorense (Visagie et al. 2014a), both included in sect. Lanata-Divaricata. However, comparisons of ITS, BenA and CaM revealed that it differs from P. singorense by six transitions in BenA and nine in CaM, three transversions in BenA and six in CaM, one indel in each of these genes, and by one transition in ITS (TreeBASE submission ID 23052). The differences between P. guaibinense and its closest related species, P. singorense, are larger than the differences between other described species in sect. Lanata-Divaricata, such as P. coerulum and P. levitum (Visagie et al. 2014a). Penicillium guaibinense grows slower than P. singorense on all media and temperatures tested, but it grows faster than P. curticaule on CYA 37 °C, CYAS and OA. Penicillium guaibinense may produce a soluble bright yellow pigment in CYA and secondary elongated phialides in ± 10 % of the conidiophores, both of these characteristics were not reported for P. singorense and P. curticaule. Penicillium guaibinense has shorter stipes than P. singorense and longer stipes than P. curticaule. Penicillium guaibinense produces mycelial coils similar to P. curticaule, but these structures were not reported for P. singorense. All macroscopic and microscopic measurements were done twice, independently, for isolates CCDCA 11512 and CCDCA 11510. For supplementary information see MycoBank.

Etymology. Named after its conidiophores that developed in tufts or dense patches. Classiﬁcation — Periconiaceae, Pleosporales, Dothideomycetes. On natural substrate. Colonies on decaying leaves dark brown to black, producing a reddish pigment. Mycelium immersed in the substrate, composed of septate, pale brown to subhyaline, smooth, 3.5 – 4 µm wide hyphae. Conidiophores macronematous, mononematous, septate, unbranched or rarely branched, caespitose, straight to flexuous, setiform and sometimes uncinated at the tip, pale brown at the base, brown towards the apex, minutely roughened at the base and at the apex, as well as in the areas nearest of conidiogenous cells, otherwise smooth, up to 500 µm long, 5 – 6 µm wide at the base, fertile at the lower-median part and sometimes also at the apex. Conidiogenous cells polyblastic, pale brown, ﬁnely roughened, intercalary and terminal, globose, subglobose or obpyriform (6 –)7.5 – 9 × 6.5 –7.5 µm. Conidia globose, aseptate, reddish brown, thick walled, dry, solitary or in short basipetal chains of 2 – 4 conidia, (6 –)6.5 – 9 µm diam, strongly echinulate, spines 1–1.5 µm long, maturation basipetal.

Conidiophores same as in natural substrate but more frequently branched and fertile at tips. Typus. BraZiL, Ceará, Missão Velha Waterfall Geosite, on decaying leaves of unidentiﬁed dicotyledonous plant, 30 Apr. 2016, T. Cantillo (holotype HUEFS 239357, culture ex-type LAMIC 110/16, ITS and LSU sequences GenBank MH051906 and MH051907, MycoBank MB827635). Notes — BLAST searches indicated that the closest relative of Periconia caespitosa represented in GenBank is P. epilithographicola CBS 144017 (ITS GenBank MF422162, Identities = 578/590 (98 %), 4 gaps (0 %)). Both species have ﬁnely roughened conidiogenous cells, produce reddish pigment, and have a similar conidial size; but, on PDA, P. epilithographicola has creeping hyphae and greyish to black conidiophores forming small agglutinated, black, sticky drop-like structures instead of caespitose, brown and setiform conidiophores with dry conidia in short chains, as occurs with P. caespitosa. These species clustered together with a maximum-likelihood bootstrap support value of 100 % but no LSU sequences of P. epilithographicola are available for comparison and therefore a phylogenetic analysis could not be performed. Given the morphological and cultural differences and also the low clustering quality values produced by both genetic markers at the generic level, we consider P. caespitosa as a new species. In addition, P. caespitosa is morphologically different from all currently accepted Periconia species (Subramanian 1955, Rao & Rao 1964, Ellis 1971, 1976, Cantrell et al. 2007, Markovskaja & Kačergius 2014, Tanaka et al. 2015, Wu et al. 2015, Liu et al. 2017, Coronado-Ruiz et al. 2018, Crous et al. 2018b, Vu et al. 2019). Among all the species of Periconia with clustered conidiophores the most similar to P. caespitosa are P. clitoriae, P. tirupatiensis, P. saraswatipurensis and P. atropurpurea, but these can be differentiated from P. caespitosa by the combination of features such as the aggrupation of conidiophores and the position of conidiogenous cells in them, conidial size and ornamentation, and pigment production on natural substrates and/or in culture. The most similar species to P. caespitosa is P. clitoriae, whose conidiophores arise in dense clusters and conidiogenous cells are located laterally at the upper three cells or at apex. Also, conidia of P. clitoriae are slightly bigger (8.5–9.5 µm diam) and also distinctly verrucose (Subramanian 1955) whereas in P. caespitosa conidia are echinulate; in addition, lateral conidiogenous cells in P. caespitosa are located in the lower portion of the conidiophore and sometimes terminally. Unfortunately, no DNA sequence data of P. clitoriae is available in GenBank for comparison. Maximum Likelihood (ML) tree inferred from ITS-LSU nrDNA sequences. Phylogenetic analyses were performed with MEGA v. 7 (Kumar et al. 2016), with the best DNA substitution model determined by the same software. Statistical support was determined by bootstrap analysis of 1 000 replicates. Bootstrap support values ≥ 70 % are depicted at the internodes. Periconia caespitosa is marked in bold face.

Note — The family Phaeothecaceae presently only includes Phaeotheca, based on P. fissurella. Phaeotheca shathenatiana B.A. Darveaux, sp. nov. Etymology. From the ﬁrst three letters of my children’s names, Shawn, Theresa and Natalie. Microscopic characteristics on 2 % malt extract agar: Hyphae brown, smooth, thin-walled, 10–20 × 3–4 µm. Conidiophores absent. Conidiogenous cells integrated, vegetative hyphae cells become conidiogenous, brown, 15–25 × 3–5 µm, expanding to 20–30 × 15–30 µm as endoconidia develop, enlarging as the cytoplasm compartmentalizes, one endoconidium forms from each compartment, successive enlarged cells resemble sausages, often one large cell that has ruptured or is near rupturing, bracketed by 3–5 lesser enlarged cells on both sides, mature conidiogenous cell ﬁnally ruptures and releases mature endoconidia. Conidia endogenous, unicellular, brown when seen en masse, pale brown when viewed individually, thin-walled, smooth, irregularly angular, especially when recently released, due to being pressed together in the conidiogenous cell, later becoming globose to subglobose, becoming less angular as they get older after release, 4–6(–7) µm diam, 5–30 per conidiogenous cell. Secondary conidia none. Culture characteristics (2 % malt extract agar) — Very slow growth, colony diameter increase is 2–4 mm/wk (27 °C) eventually stopping, not covering plate. Mycelium dense, growing edge sharp, aerial hyphae developing just behind slowly advancing submerged hyphae, aerial hyphae on older areas, exudate droplets on surface containing conidia, centre of colony becoming raised. Colour dark brown to black, reverse black. Typus. USA, Alaska, Anchorage, from twig and cone litter, 30 Sept. 1997, coll. D. Duffy, isol.

Notes — The current fungus shares generic diagnostic features of Phaeotheca such as predominant endogenous conidiogenesis, slow restricted growth at room temperature, and angular brown conidia (Sigler et al. 1981.) However, P. shathenatiana differs from the other four species of the genus by: P. fissurella usually has 1–3 (rarely more) endoconidia per conidiogenious cell (Sigler et al. 1981); P. dimorphospora forms hyaline, cylindrical secondary conidia from primary endocondia (DesRochers & Ouellette 1994); P. triangularis and P. salicorniae both produce septate endoconidia (De Hoog et al. 1997, Crous et al. 2016b). Our phylogenetic analysis using partial LSU sequence data along with described species of Phaeotheca including members of asexual Capnodiales from an alignment published by Bose et al. (2014), shows strain P. shathenatiana clusters with the type species P. fissurella as a strongly supported clade (91 % RAxML bootstrap support). Our analysis also shows that Phaeotheca is a polyphyletic genus consistent with conclusions drawn in previous studies (Crous et al. 2016b). Phaeotheca represents an undescribed, monotypic family in Capnodiales, for which Phaeothecaceae is herewith introduced. There are many other genera that produce endoconidia, usually to a minor extent, but relatively few rely on this mode as their main form of conidiogenesis. Several genera of the latter type are Coccidioides, Phaeothecoidea, Endoconidioma and Hyphospora (Seifert et al. 2011.) Endospores of Coccidioides come from sphaerules rather than intercalary hyphal cells and it has alternate-arthric conidia which P. shathenatica does not have (Seifert et al. 2011). Phaeothecoidea differs in that the endoconidia are verruculose, 1–2-septate, and give rise to additional endoconidia. However, the photomicrographs of Phaeothecoidea melaleuca look very similar to the current fungus (Crous et al. 2010). Endoconidioma differs in that it has a pycnidium-like conidiomata and solitary blastoconidia. Seifert et al. (2011) considers Endoconidioma a coelomycete. Colour illustrations.

Hyphospora differs in that it has hyaline mycelium and conidia and a depressed hemispheric central part of the colony surrounded by a halo of hyaline hyphae in the agar (Ramaley 1996). Blaise A.

Pseudocercospora species can be found as saprobes, endophytes, hyperparasites, being very common as plant pathogens – causing mainly leaf spots (Crous et al. 2013, Braun et al. 2016, Guatimosim et al. 2016). Cercosporoid fungi have been reported as host-speciﬁc (Guatimosim et al. 2016, Silva et al. 2016). Four cercosporoid fungi have been described from Styrax spp.: Passalora styracis, Cercospora apii s.lat. (= Cercospora styracicola), Pseudocercospora fukuokaensis and Cercoramularia koreana (Crous & Braun 2003, Videira et al. 2017). Morphologically, P. styracina clearly differs from P. fukuokaensis and P. brackenicola by having external mycelium colonising the trichomes and stromata absent. Additionally, the conidia length of P. styracina (22.5 – 47.5 µm) are shorter than P. fukuokaensis (30 –70 µm) and P. brackenicola (20 –77 µm) (Chupp 1954, Guatimosim et al. 2016). Pseudocercospora styracina does not correspond to any sequence available in GenBank at present. Hence, it is described here as a new species. Based on a megablast search of NCBIs GenBank nucleotide database, the ITS sequence is identical to P. norchiensis (GenBank MF663573), P. brackenicola (GenBank NR_147290) and P. abacopteridicola (GenBank KT037518).

Etymology. Name refers to the Spanish region where the species was collected. Classiﬁcation — Microthyriaceae, Microthyriales, Dothideomycetes. Mycelium consisting of branched, septate, pale brown, smoothwalled to verruculose hyphae of 1–1.5 µm diam. Conidiophores mononematous, dimorphic: microconidiophores reduced to conidiogenous cells on hyphae, 13 –19 µm high, apex truncate 2 µm wide, pale brown; macroconidiophores unbranched, erect, subcylindrical, with up to 3-septate, pale brown to brown, often verruculose towards the apex, smooth- and thick-walled towards an often swollen base, up to 55 µm long (up to 120 µm long on the natural substratum), 2 – 3 µm wide. Conidiogenous cells terminal or subterminal, mono- or polyblastic, with up to 4 inconspicuous conidiogenous loci, verruculose, pale brown, 11– 21.5 × 1.5 – 3 µm. Ramoconidia subcylindrical, aseptate, pale brown, smooth to verruculose, 7.5 –11 × 2 – 3 µm, forming conidia in acropetal branched chains. Conidia cylindrical to ellipsoidal, aseptate, pale brown, smooth-walled to verruculose, 6 –12 × 1– 3 µm. Sexual morph not observed. Culture characteristics — Colonies on PDA reaching 8 – 9 mm diam after 30 d at 25 °C, golden grey to black, velvety, erumpent, aerial mycelium scarce,feathery margin; reverse dark brown to black. On OA reaching 5 – 6 mm diam after 30 d at 25 °C, olive brown to black, slightly dusty, flat, aerial mycelium scarce; reverse dark brown to black. Notes — Pseudopenidiella was introduced to accommodate P. piceae (Crous et al. 2012b), a hyphomycetous fungus morphologically similar to Cladosporium, but phylogenetically distant to the family Cladosporiaceae (Capnodiales, Dothideomycetes). The genus was characterised by the formation of dimorphic conidiophores with terminal aseptate ramoconidia producing branched conidial chains, and by the absence of coronate-type scars on conidia or conidiogenous cells. In addition to the type, P. pini (formerly Polyscytalum pini; Kirk 1983) is currently included in Pseudopenidiella (Kirk 2014). However, the phylogeny of this latter species is obscure since only herbarium material (holotype IMI 242163) is available for comparison. Pseudopenidiella pini is characterised by the production of short and broad denticulate conidiogenous cells, a feature not described in Pseudopenidiella. Pseudopenidiella gallaica differs from P. piceae in its shorter conidiophores (up to 55 µm long in culture – up to 120 µm on the natural substratum – vs 150 μm long in P. piceae) and slightly longer conidia (up to 12 µm in P. gallaica vs up to 10 µm in P. piceae). Based on a megablast search of NCBIs GenBank nucleotide, LSU sequence of P. gallaica showed a similarity of 95 % (742/ 785) with that of P. piceae (CBS 131453, GenBank NG_042681); while ITS sequence did not reveal any close hits. Our phylogenetic reconstruction shows that Pseudopenidiella is related to the members of the family Microthyriaceae (Abarca et al. 2011, Singtripop et al. 2016). Typus.

Conidia solitary, dry, obclavate, hyaline, (30 –)36 – 52(– 65) × 10 –13 µm, 2(– 3)-septate, hilum often protuberant, conidia produce secondary conidiophore. Sexual morph unknown. Culture characteristics — Colonies on OA transparent, buff, reaching 42 mm diam after 1 wk at 23–25 °C; on PDA transparent, white, and straw reverse, reaching 26 mm diam after 1 wk at 23 – 25 °C. Typus. iran, Guilan province, Lasht-e Nesha city, on infected leaves of Cyperus sp., 19 Oct. 2017, G. Ghorbani (holotype UTFC-PO20, culture ex-type UTFC-PO21, ITS, LSU, RPB1 and CAL sequences GenBank MH780926, MH780974, MH699975 and MH699978, MycoBank MB826968). Notes — This species is similar to Ps. higginsii, Ps. cyperi, Ps. iraniana, Ps. kyllingae and Ps. hagahagae in having 2-septate conidia (Klaubauf et al. 2014, Pordel et al. 2017). However, the conidia and conidiophores of Ps. persiana are larger than those of Ps. higginsii, Ps. cyperi, Ps. kyllingae and Ps. hagahagae. It differs from Ps. iraniana in conidial shape and size. To clarify the identiﬁcation of Ps. persiana within Pseudopyricularia, CAL / ITS/RPB1 sequences were combined in a phylogenetic analysis. The phylogenetic tree suggested phylogenetic relatedness of the taxa from Iran to Pseudopyricularia with high statistical support (Bayesian Posterior Probability = 100 %, Maximum Likelihood bootstrap support =100 %). Our and previous data identiﬁed seven species in Pseudopyricularia, which is sister to Macgarvieomyces. Macgarvieomyces is morphologically well-separated from Pseudopyricularia because the former produces chlamydospores, has conidiophores that are mostly unbranched and conidia that are narrowly obclavate, granular and 1-septate. Isolates of Ps. persiana clustered sister to Ps. higginsii. However, conidia and conidiophores sizes of Ps. persiana are distinct from those of Ps. higginsii. Maximum likelihood and Bayesian Inference analyses of the combined CAL, ITS and RPB1 sequences support the classiﬁcation of the new species in Pseudopyricularia, a genus that is distantly related to Pyricularia. Morphological characteristics combined with analyses of DNA sequences allowed us to identify and illustrate Ps. persiana as a novel species from Iran.

Blair, sp. nov. Etymology. Named in honour of Carolyn W. and Robert S. Wohlsen, who founded Millport Conservancy in Lititz, Pennsylvania, USA in 1969. Classiﬁcation — Pythiaceae, Pythiales, Oomycetes. Main hyphae up to 5 µm diam. Sporangia ﬁlamentous noninflated, giving rise to vesicles containing abundant zoospores at room temperature on 0.2 % water agar with sterile grass blades. Encysted zoospores 7–10 µm (av. 8.5 µm) diam, form large grape-like clusters. Oogonia produced in single culture after several weeks, globose, smooth-walled, mostly intercalary, occasionally catenulate, 20 – 23 µm (av. 21.6 µm) diam. Antheridia monoclinous, one per oogonium. Oospores single, aplerotic or nearly plerotic, globose, 16 –19 µm (av. 17.9 µm) diam, wall 1.1–1.6 µm (av. 1.3 µm) thick. Culture characteristics — Produces dense, aerial hyphae on potato-dextrose agar (PDA), thin aerial hyphae with no special pattern on potato-carrot (PCA) and clariﬁed V8 agars (V8A), and a chrysanthemum pattern with light aerial hyphae on cornmeal agar (CMA). Colony diam. after 24 h at 25 °C on PDA 26 mm, PCA 28 mm, V8A 25 mm, CMA 23 mm. Optimal growth at 28 °C. Notes — Isolates were ﬁrst collected in 2013 and subsequently in 2015 and 2017; this species is commonly baited from stream water with hemp seed, or in association with various submerged pondweeds. Despite extensive stream sampling in the area, Pythium wohlseniorum has only been recovered to date from Lititz Run at Millport Conservancy. Phylogenetic analysis of both mitochondrial and nuclear loci place P. wohlseniorum in Pythium Clade B2 sensu Levesque & De Cock (2004), closely related to P. pachycaule. Sequences from 11 isolates were identical for COII, ITS, LSU and betatubulin loci; a single nucleotide polymorphism was present in COI sequences. Pythium wohlseniorum has a higher optimal temperature compared to P. pachycaule, and a faster growth rate at 25 °C than P. pachycaule, P. coloratum, P. diclinum, P. dissotoum and P. lutarium. Other morphological features overlap with other Clade B2 species. Typus. uSa, Pennsylvania, Warwick Township, Millport Conservancy, from stream water, 12 May 2015, J.E. Blair & S.

Silva, R.J.V. Oliveira, Souza-Motta, J.L. Bezerra & G.A. Silva, sp. nov. Notes — The genus Simplicillium was introduced by Zare & Gams (2001). Members of this genus include endophytic species, parasites and saprobes isolated from different environments such as soil, freshwater, plants and other parasitic fungi (Liu & Cai 2012, Nonaka et al. 2013, Gomes et al. 2018). Morphologically, S. filiforme is similar to S. obclavatum and S. chinense which also form conidial chains. However, S. filiforme is different from S. obclavatum and S. chinense based on the size and shape of its conidia. Simplicillium filiforme produces conidia that are long, fusoid to ﬁliform, catenulate, straight to curved (7.2–12.5 × 1 μm) while S. obclavatum produces conidia obclavate to ellipsoidal (2.5 – 3.5 × 1– 2 μm) and S. chinense produces conidia that are mostly ovoid, ellipsoidal or cylindrical (3.5 – 5 × 1–1.5 μm). Based on ITS rDNA, the new species S. filiforme is phylogenetically close to S. coffeanum, though S. coffeanum form macroconidia and microconidia with subglobose to ellipsoidal heads at the apex of the phialides (Gomes et al. 2018). Etymology. The name refers to the ﬁliform shape of its conidia. Classiﬁcation — Cordycipitaceae, Hypocreales, Sordariomycetes. Mycelial hyphae thin, hyaline, septate, branched, smooth-walled, 1.8–2.7 µm diam. Phialides hyaline, produced on aerial hyphae, solitary, elongate, slightly tapering towards the apex, 9–18 × 1 µm. Conidia long, fusoid to ﬁliform, hyaline, smooth-walled, catenulate, straight to curved, sometimes forming zigzag chains, 7.2–12.5 × 1 µm. Culture characteristics — Colonies on PDA reaching 44 mm diam after 10 d at 25 °C, white, slow growth, moderate aerial mycelium, cottony surface, compact. Reverse white to yellowish cream. Colonies on MEA reaching 40 mm diam after 10 d at 25 °C, white, slow growth, cottony surface, moderate aerial mycelium. Reverse dark yellow. Typus.

Conidiogenous cells phialidic, hyaline, cylindrical to barrel-shaped or ampulliform, 5–8.5 × 1.5–2 μm, smooth-walled, solitary or laterally disposed on the conidiophores. Conidia hyaline, aseptate, smooth- and thin-walled, guttulate, cylindrical to navicular, 4–5 × 1.5– 2 μm. Culture characteristics — Colonies on OA reaching 7 mm diam after 14 d at 25 ± 1 °C, margins lobate, flattened, both surface and reverse black (M. 2F1).

Notes — The geographical origin of the strains (USA and Spain) and the nature of the substrates from which they were isolated (human and environmental ones) probably indicates a wide distribution of this new taxon. Superstratomyces tardicrescens is distinguished from the rest of the species of the genus by its small conidia produced on well-developed conidiophores (larger, and produced on single phialides in the rest of the species) (Van Nieuwenhuijzen et al. 2016).

Jurjević (holotype BPI 910643, cultures ex-type NRRL 66822 = ITEM 17527 = EMSL 2233, ITS, BenA, CaM and rpb2 sequences GenBank MH281565, MH282578, MH282579 and MH282577, MycoBank MB828092). Notes — BLAST searches of the sequences of Talaromyces iowaense showed β-tubulin (BenA) similarity to T. rademirici (83 %), calmodulin (CaM) similarity to T. purpureus (82 %), RNA polymerase II second largest subunit (rpb2) similarities to T. rademirici (89 %) and T. purpureus (87 %), and ITS similarity to T. purpureus was 91 %. A phylogenetic tree with three genes was generated (no T. rademirici calmodulin sequence available), and the branch resolution improved when this species is included. The maximum likelihood analysis of DNA sequences show net separation of this new species from the other well-resolved branches. Talaromyces iowaensis clusters with the species from Talaromyces sect. Purpurei. Talaromyces iowaense is distinguished from other Talaromyces species by production of intense red (light coral red to Pompeian red, R8) soluble pigments on MEA, good growth on MEA but restricted on CYA, growth on CREA, no growth at 37 °C, and conidia 2 – 2.5(– 3) × 2 – 3 µm. The closely related T. rademirici demonstrates no soluble pigments on MEA, good growth on CYA and MEA, no growth on CREA, growth at 37 °C, and has larger conidia 2.5 – 4 × 1.5– 2.5 µm.

Notes — Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence are T. gigantea (GenBank AY331002 and AY331001; Identities = 432/442 and 431/442 (98 %), no and 1 gap, respectively), T. acerosa (GenBank AY330996; Identities = 440/455 (97 %), 1 gap) and T. boonjiensis (GenBank AY330995; Identities = 424/442 (96 %), 1 gap). Closest hits using the LSU sequence had highest similarity to T. fabacearum (GenBank NG_059767 and KY212762; Identities = 499 /518 (96 %), 6 gaps (1 %)), T. nivea (GenBankEU825200; Identities = 497/518 (96 %), 6 gaps (1 %)) and Chaetosphaeria rivularia (GenBankKR347357; Identities = 490/519 (94 %), 7 gaps (1 %)). Morphologically, T. pindobacuensis differs from T. gigantea based on the size of the microawns (65 – 280 × 2.5 – 8 μm) and conidial setula (6 –12.5 μm long) (Paulus et al. 2004, Silva & Grandi 2013). Furthermore, the new species has synnematous conidiomata with synchronic extensions and 0 –1-septate microawns. Thozetella pindobacuensis differs from T. acerosa, T. boonjiensis and T. nivea in the production of sporodochial conidiomata and the shape of its microawns. In this paper, we considered T. acerosa and T. boonjiensis as distinct species based on molecular data (Paulus et al. 2004, Jeewon et al. 2009, Perera et al. 2016). pindopacuensis MH595849/MH595851 Thozetella pindopacuensis MH595850 Thozetella gigantea AY331002 70/1 100/1 Thozetella gigantea AY331001 Thozetella acerosa AY330996 Thozetella boonjiensis AY330994 88/1 100/1 Thozetella boonjiensis AY330995 100/1 Thozetella queenslandica AY330998 Thozetella queenslandica AY330997 Thozetella nivea EU825201/EU825200 Thozetella pinicola EU825197/EU825195 72/0.98 Thozetella falcata AY331000 Thozetella falcata AY331004 72 Thozetella cristata KJ183032 79/1 Thozetella falcata AY331003 87/1 Thozetella falcata AY330999 74 Thozetella fabacearum KY212754/KY212762 100/1 Thozetella havanensis EF029184 Chaetosphaeria rivularia KR347356/KR347357 Menispora tortuosa AF178558/AF178558 Sporoschisma hemipsilum KX455869/KX455862 0.05 100/1 Thozetella Maximum likelihood (ML) tree based on combined dataset of ITS and LSU sequences.

Cultures sterile. Typus. BraZiL, Viçosa, campus of Universidade Federal de Viçosa, on Coussapoa floccosa (Cecropiaceae), 18 July 2014, R.W. Barreto (holotype VIC44404, culture ex-type COAD1824; ITS and LSU sequences GenBank MG780415 and MH716814, MycoBank MB827438). Notes — Xenosonderhenia was recently established to accommodate two leaf spot fungal pathogens belonging to the Mycosphaerellaceae. Xenosonderhenia is a pleomorphic genus including the type species X. syzygii – with no known sexual morph but described as having two asexual morphs: a pycnidial morph and a hyphomycete synasexual morph seen only in culture (Crous et al. 2012b) and X. eucalypti – known only from its ascomatal morph (Crous et al. 2014b). Phylogenetically, COAD1824 clusters with Mycosphaerella elaeocarpi – a fungus lacking an asexual morph – and with Xenosonderhenia. Morphological features such as size and surface of conidia (ﬁnely verruculose in X. syzygii but smooth in the newly proposed species) and phylogenetic data indicated that the fungus on C. floccosa represents a new species of Xenosonderhenia. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence were X. syzygii (GenBank NR_111763; Identities = 461/492 (94 %), 7 gaps (1 %)), X. eucalypti (GenBank NR_137937; Identities = 457/492 (93 %), 6 gaps (1 %)) and Mycosphaerella elongata (GenBank EF394833; Identities = 456/492 (93 %), 8 gaps (1 %)). Closest hits for LSU were M. elaeocarpi (GenBank EU040212; Identities = 858/868 (99 %), 4 gaps (0 %)), X. syzygii (GenBank NG_042685; Identities = 852/864 (99 %), 2 gaps (0 %)) and X. eucalypti (GenBank NG_058120; Identities = 812/823 (99 %), no gaps). Xenosonderhenia coussapoae represents an addition to the known mycobiota of C. floccosa and, if proven speciﬁc to this host, may represent an endangered species of microfungi, as are other fungal species described from this highly endangered Brazilian tree species (Rocha et al. 2010).

Notes — Maximum likelihood phylogenetic analyses of ITS sequences under a GTR model grouped the new sequences in a well-supported clade (bootstrap support value > 95 %) with Xylodon niemelaei, X. rhizomorphus and X. reticulatus. No LSU GenBank sequences were available for X. reticulatus. Distribution and morphological diagnostic characters for each species are shown in Table 1. Xylodon jacobaeus is similar to these species, but differs in having subcylindrical to utriform cystidia, capitate hyphae and wider spores. Topology of ITS tree obtained by Maximum Likelihood Inference conducted in RAxML v. 8.2.10 on CIPRES Science Gateway v. 3.3 (Miller et al. 2010). Two sequences of X. paradoxus were used as outgroup. Bootstrap support values (> 50 %) are indicated on the branches (bootstrap iterations = 1 000). The X. jacobaeus clade is marked with a green block; the accession numbers from the EMBL/GenBank database are indicated at the terminal nodes. The asterisk (*) after the EMBL/GenBank accession numbers are sequences obtained for this study.
