... Phylogenetic analyses showed that freshwater hyphomycetes are polyphyletic and distributed in different phyla, such as Ascomycota and Basidiomycota, the dominant phylum being Ascomycota [6,29,30,36], with most species reported in Dothideomycetes and Sordariomycetes [29,30,37], and a few species belonging to Eurotiomycetes [38][39][40]. Some freshwater hyphomycetes have been linked with their sexual morphs [6,29,[41][42][43][44][45]. ...
Freshwater hyphomycetes are a highly diverse group of fungi with a worldwide distribution and have been mostly reported from tropical and subtropical regions. During investigations of freshwater fungi from the Greater Mekong subregion in China and Thailand, sixteen freshwater hyphomycetes (three of them belong to the class Dothideomycetes while thirteen belong to the class Sordariomycetes) were collected. Based on morphology and multi-gene phylogenetic analyses, Neospadicoides thailandica, Pseudodactylaria aquatica, Sporidesmium nujiangense, Tetraploa thailandica, Vamsapriya aquatica and Wongia fusiformis are described as new species; Aquapteridospora bambusinum is proposed as a new combination; Acrodictys liputii, Chloridium gonytrichii, Pseudoberkleasmium chiangmaiense, Pleomonodictys capensis, Sporidesmium aturbinatum and Vamsapriya indica are reported as new country records; and Sporidesmium tropicale, Sporoschisma chiangraiense and Sporoschisma longicatenatum are introduced as three new collections. In addition, a checklist of freshwater fungi from China over the last five years is also provided.
... Remarks:-this species forms muriform conidia larger than 100 μm, golden-brown to olive, abundant. Tanney & Miller (2017) found that this is the asexual phase of Neoacanthostigma septoconstrictum (Prom. & A.N. Mill.) ...
The tropical montane cloud forest is an important reservoir of the diversity of Mexican ascomycetes. We cite and describe 17 species that had not been recorded in this vegetation type. Fifteen of them are new records for Mexico. Some of these species are associated with angiosperms and some with other fungi. Ongoing efforts are required to carry out floristic, taxonomic, phylogenetic and ecological studies of this group of fungi in such a diverse ecosystem that is cataloged as threatened.
... The diversity of trophic and reproductive strategies of fungi and their often complex lifecycles add further complications. What is perceived as phenotypically distinct entities may be manifestations of one and the same fungus, often representing sexual versus asexual forms (Kendrick 1979;Aoki and O'Donnell 1999;Covert et al. 2007;Wingfield et al. 2012;Rossman et al. 2016;Tanaka and Honda 2017;Tanney and Miller 2017). Exemplar cases are the rust fungi Kolmer et al. 2018), which can produce up to seven morphologically and functionally distinct types of spores (Bruckart et al. 2010). ...
True fungi (Fungi) and fungus-like organisms (e.g. Mycetozoa, Oomycota) constitute the second largest group of organisms based on global richness estimates, with around 3 million predicted species. Compared to plants and animals, fungi have simple body plans with often morphologically and ecologically obscure structures. This poses challenges for accurate and precise identifications. Here we provide a conceptual framework for the identification of fungi, encouraging the approach of integrative (polyphasic) taxonomy for species delimitation, i.e. the combination of genealogy (phylogeny), phenotype (including autecology), and reproductive biology (when feasible). This allows objective evaluation of diagnostic characters, either phenotypic or molecular or both. Verification of identifications is crucial but often neglected. Because of clade-specific evolutionary histories, there is currently no single tool for the identification of fungi, although DNA barcoding using the internal transcribed spacer (ITS) remains a first diagnosis, particularly in metabarcoding studies. Secondary DNA barcodes are increasingly implemented for groups where ITS does not provide sufficient precision. Issues of pairwise sequence similarity-based identifications and OTU clustering are discussed, and multiple sequence alignment-based phylogenetic approaches with subsequent verification are recommended as more accurate alternatives. In metabarcoding approaches, the trade-off between speed and accuracy and precision of molecular identifications must be carefully considered. Intragenomic variation of the ITS and other barcoding markers should be properly documented, as phylotype diversity is not necessarily a proxy of species richness. Important strategies to improve molecular identification of fungi are: (1) broadly document intraspecific and intragenomic variation of barcoding markers; (2) substantially expand sequence repositories, focusing on undersampled clades and missing taxa; (3) improve curation of sequence labels in primary repositories and substantially increase the number of sequences based on verified material; (4) link sequence data to digital information of voucher specimens including imagery. In parallel, technological improvements to genome sequencing offer promising alternatives to DNA barcoding in the future. Despite the prevalence of DNA-based fungal taxonomy, phenotype-based approaches remain an important strategy to catalog the global diversity of fungi and establish initial species hypotheses.
... Berkleasmium is polyphyletic, with species having similar characteristics, but which are phylogenetically distinct (Pinnoi et al. 2007;Hu et al. 2010;Lu et al. 2018b). A study by Tanney and Miller (2017) was able to obtained several fresh collections of Berkleasmium and compared those with the reference specimens of Berkleasmium concinnum. Re-examination of the type species placed the generic type of Berkleasmium in Tubeufiales. ...

... Berkleasmium is polyphyletic, as many species clustered in different clades and even in different families in the phylogenetic analysis (Fig. 37). Moreover, the type species of the genus (Berkleasmium concinnum) has been moved to Tubeufiaceae (Tubeufiales) (Tanney and Miller 2017;Lu et al. 2018). Berkleasmium concinnum has obovoid conidia with a scar (hilum) at base and cylindrical conidiogenous cells with a dark apex (Ellis 1971;Bussaban et al. 2001;Seifert et al. 2011;Tanney and Miller 2017). ...

This paper provides illustrated descriptions of micro-fungi newly found on Pandanaceae in China and Thailand. The fungi are accommodated in 31 families. New taxa described include a new family, seven new genera, 65 new species, 16 previously known species. A new family: Malaysiascaceae (Glomerellales). New genera are Acremoniisimulans (Plectosphaerellaceae), Pandanaceomyces, Pseudoachroiostachy (Nectriaceae), Pseudohyaloseta (Niessliaceae), Pseudoornatispora (Stachybotriaceae) and Yunnanomyces (Sympoventuriaceae). New species are Acremoniisimulans thailandensis, Beltrania krabiensis, Beltraniella pandanicola, B. thailandicus, Canalisporium krabiense, C. thailandensis, Clonostachys krabiensis, Curvularia chonburiensis, C. pandanicola, C. thailandicum, C. xishuangbannaensis, Cylindrocladiella xishuangbannaensis, Dictyochaeta pandanicola, Dictyocheirospora nabanheensis, D. pandanicola, D. xishuangbannaensis, Dictyosporium appendiculatum, Di. guttulatum, Di. hongkongensis, Di. krabiense, Di. pandanicola, Distoseptispora thailandica, D. xishuangbannaensis, Helicoma freycinetiae, Hermatomyces biconisporus, Lasiodiplodia chonburiensis, L. pandanicola, Lasionectria krabiense, Menisporopsis pandanicola, Montagnula krabiensis, Musicillium pandanicola, Neofusicoccum pandanicola, Neohelicomyces pandanicola, Neooccultibambusa thailandensis, Neopestalotiopsis chiangmaiensis, N. pandanicola, N. phangngaensis, Pandanaceomyces krabiensis, Paracylindrocarpon nabanheensis, P. pandanicola, P. xishuangbannaensis, Parasarcopodium hongkongensis, Pestalotiopsis krabiensis, P. pandanicola, Polyplosphaeria nabanheensis, P. pandanicola, P. xishuangbannaensis, Pseudoachroiostachys krabiense, Pseudoberkleasmium pandanicola, Pseudochaetosphaeronema pandanicola, Pseudohyaloseta pandanicola, Pseudoornatispora krabiense, Pseudopithomyces pandanicola, Rostriconidium pandanicola, Sirastachys phangngaensis, Stictis pandanicola, Terriera pandanicola, Thozetella pandanicola, Tubeufia freycinetiae, T. parvispora, T. pandanicola, Vermiculariopsiella hongkongensis, Volutella krabiense, V. thailandensis and Yunnanomyces pandanicola. Previous studies of micro-fungi on Pandanaceae have not included phylogenetic support. Inspiration for this study came from the book Fungi Associated with Pandanaceae by Whitton, McKenzie and Hyde in 2012. Both studies reveal that the micro-fungi on Pandanaceae is particularly rich in hyphomycetes. All data presented herein are based on morphological examination of specimens, coupled with phylogenetic sequence data to better integrate taxa into appropriate taxonomic ranks and infer their evolutionary relationships.
... Clade 35 (30 taxa) represents the genus Berkleasmium established by Zobel (Corda 1854) with the type species B. concinnum. Tanney and Miller (2017) found that B. concinnum is the asexual morph of Neoacanthostigma septoconstrictum. In this study, we synonymize Neocanthostigma aquaticum, N. brunneisporum, N. guangxiense, N. latisporum, N. thailandicum and introduce two new species, Berkleasmium fusiforme and B. longisporum. ...
... Boonmee et al. (2014) synonymized it under Neoacanthostigma filiforme based on phylogenetic evidence. However, Tanney and Miller (2017) pointed out that the transfer of Acanthostigma filiforme to Neoacanthostigma was unwarranted based on ITS-LSU phylogenetic analyses. Our phylogenetic analyses also showed that two taxa of A. filiforme (ANM101 and ANM514) formed a distinct clade from Neoacanthostigma and Acanthostigma. ...
... Moore (1958) re-established Berkleasmium to accommodate sporodochial species previously placed in Sporidesmium. Berkleasmium currently comprises 37 species characterized by sporodochial conidiomata bearing macronematous conidiophores, monoblastic conidiogenous cells and brown or black, dry, rhexolytically-seceding dictyoconidia (Moore 1958;Ellis 1971;Bussaban et al. 2001;Zhao and Zhang 2004;Pinnoi et al. 2007;Seifert et al. 2011;Qu et al. 2014;Tanney and Miller 2017). Tanney and Miller (2017) reported that the type species of Berkleasmium, B. concinnum, was the asexual morph of Neoacanthostigma septoconstrictum. ...
This study deals with an extensive taxonomic reevaluation focusing on phylogenetic relationships and morphological characterization of Tubeufiales, especially those helicosporous hyphomycetes which are difficult to identify. Based on evidence from DNA sequence data and morphology, we introduce 13 new genera in the family Tubeufiaceae, viz. Acanthotubeufia, Dematiohelicoma, Dematiohelicomyces, Dematiohelicosporum, Dematiotubeufia, Helicoarctatus, Helicohyalinum, Helicotruncatum, Neochlamydotubeufia, Neohelicoma, Pleurohelicosporium, Pseudohelicomyces and Pseudohelicoon; transfer Chaetosphaerulina from Dothideomycetes genera incertae sedis, and Artocarpomyces and Helicodochium from Ascomycetes genera incertae sedis into Tubeufiaceae; introduce 52 new species, viz. Berkleasmium fusiforme, B. longisporum, Chlamydotubeufia cylindrica, Dematiohelicosporum guttulatum, Helicoarctatus aquaticus, Helicodochium aquaticum, Helicohyalinum infundibulum, Helicoma aquaticum, H. brunneisporum, H. cocois, H. rufum, H. fusiforme, H. longisporum, H. multiseptatum, H. rubriappendiculatum, H. septoconstrictum, H. tectonae, Helicomyces hyalosporus, Helicosporium aquaticum, H. flavisporum, H. setiferum, H. vesicarium, H. viridiflavum, Neochlamydotubeufia fusiformis, Neohelicomyces hyalosporus, Neohelicosporium acrogenisporum, N. astrictum, N. ellipsoideum, N. irregulare, N. krabiense, N. laxisporum, N. ovoideum, Pleurohelicosporium parvisporum, Pseudohelicomyces aquaticus, P. hyalosporus, Tubeufia abundata, T. bambusicola, T. brevis, T. brunnea, T. chlamydospora, T. dictyospora, T. eccentrica, T. fangchengensis, T. hechiensis, T. inaequalis, T. krabiensis, T. rubra, T. sessilis, T. sympodihylospora, T. sympodilaxispora, T. taiwanensis and T. tratensis; provide 43 new combinations, viz. Acanthohelicospora guianensis, Acanthotubeufia filiforme, Berkleasmium aquatica, B. guangxiense, B. latisporum, B. thailandicum, Dematiohelicoma perelegans, D. pulchrum, Dematiohelicomyces helicosporus, Dematiotubeufia chiangraiensis, Helicohyalinum aquaticum, Helicoma elinorae, H. gigasporum, H. hongkongense, H. linderi, H. nematosporum, H. pannosum, H. serpentinum, Helicomyces chiayiensis, Helicotruncatum palmigenum, Neochlamydotubeufia khunkornensis, Neohelicoma fagacearum, Neohelicomyces pallidus, Neohelicosporium abuense, N. aurantiellum, N. griseum, N. morganii, N. myrtacearum, N. nizamabadense, N. sympodiophorum, N. taiwanense, N. vesiculiferum, Pseudohelicomyces indicus, P. paludosus, P. talbotii, Pseudohelicoon gigantisporum, P. subglobosum, Tubeufia dentophora, T. geniculata, T. lilliputea, T. machaerinae, T. sympodiophora and T. xylophila; introduce 16 new records, viz.

The taxonomy of Helicoma, Helicomyces and Helicosporium is revisited based on phylogenetic analyses and morphological evidence. Neorhamphoria is transferred to Bezerromycetaceae. Three species are excluded from the genus Chlamydotubeufia, twelve species from Helicoma, four species from Helicomyces, 25 species from Helicosporium, six species from Neoacanthostigma and one species from Tubeufia. A multi-gene phylogenetic tree based on maximum likelihood and Bayesian analyses of ITS, LSU, RPB2 and TEF1α sequence data of species of Tubeufiales is provided. Detailed descriptions and illustrations are provided, as well as the morphological comparison with similar taxa are explored. The checklist of accepted Tubeufiales species and re-organised Tubeufiales species are provided.
... Dictyosporella hydei is morphologically similar to some species of Berkleasmium Zobel. Berkleasmium currently comprises 37 dematiaceous hyphomycetous species characterized by sporodochial conidiomata bearing macronematous conidiophores and monoblastic conidiogenous cells that give rise to brown or black, dry, rhexolyticallyseceding, dictyoconidia (Tanney & Miller 2017). Of the 37 Berkleasmium species, Dictyosporella hydei mostly resembles Berkleasmium fusiforme G.Z. Zhao, B. lingula R.T. Moore and B. micronesicum Matsush. in the conidial shape. ...
A new species Dictyosporella hydei was collected on submerged wood in Yunnan Province, China. The new species is characterized by globose to broadly cylindrical, muriform and brass coloured conidia consisting of multiple angular, subglobose cells. Its affinity to Dictyosporella was inferred from phylogenetic analysis based on LSU data. The new species together with the other two species of Dictyosporella formed a well-supported clade which was closely related to Distoseptisporaceae.
... The family was introduced to accommodate bitunicate ascomycetes occurring as saprobes on decaying wood (Barr 1979(Barr , 1980Boonmee et al. 2011Boonmee et al. , 2014Hyde et al. 2013). Taxa in Tubeufiaceae are characterized by superficial, soft and fleshy, pallid to bright, or black ascomata, bitunicate asci, and hyaline to pale brown, Thaxteriella, Thaxteriellopsis and Tubeufia (Boonmee et al. 2011Hyde et al. 2013;Wijayawardene et al. 2014;Brahamanage et al. 2017;Chaiwan et al. 2017;Luo et al. 2017;Tanney and Miller 2017). Recent phylogenetic investigations have reported Berkleasmium concinnum as the asexual morph of Neoacanthostigma septoconstrictum, hence Tanney and Miller (2017) synonymized N. septoconstrictum under B. concinnum based on the priority of Berkleasmium over Neoacanthostigma. ...

However, the taxonomic boundaries between these two genera are still uncertain as the asexual morph of Neoacanthostigma is characterized by helicomyces-like asexual morph Hyde et al. 2016). ...
... Phylogenetic analyses obtained from ML, MP and BI were similar in overall topologies and were not significantly different (data not shown). Phylogeny of genera in Tubeufiaceae were well-resolved and depict relationships similar to previous studies Chaiwan et al. 2017;Dai et al. 2017;Doilom et al. 2017;Lu et al. 2017a, b, c;Luo et al. 2017;Tanney and Miller 2017). ...
Two novel species of bambusicolous fungi in the genus Kamalomyces, collected from northern Thailand, are described and illustrated herein. Kamalomyces bambusicola and K. thailandicus spp. nov. are typical of the genus Kamalomyces (Tubeufiaceae, Tubeufiales) and are morphologically distinct from known species with respect to their size of ascomata, asci and ascospores, ascospore septation and peridium structure, including the subiculum comprising hyphae on the host surface. Morphological examination reveals that the asexual morph of K. bambusicola is associated with its sexual morph in a subiculum forming dictyochlamydosporous conidia, which are similar to the asexual morph of Chlamydotubeufia. Phylogenetic analyses of combined LSU, ITS and TEF1-α sequence data also support these two species as distinct and confirm their phylogenetic affinities within the Tubeufiaceae. In particular, Kamalomyces shares a close phylogenetic relationship to Helicoma.
A new genus Globosus with a new species G. polychromus is introduced from a freshwater habitat in Thailand, based on morphological characters with evidence from phylogenetic analysis of concatenated internal transcribed spacer region ITS4-5.8S -ITS5 (ITS), nuclear large subunit rDNA (28S) and nuclear small subunit rDNA (18S) sequence data. Phylogenetically, Globosus clustered with Quadrisporella and Setoapiospora in Muyocopronaceae with 100% ML/ 1.00 BYPP support. However, there are differences in morphology. Globosus is characterized by its hyphomycetous structure and having pink or yellow colonies in culture on the natural substrate and PDA, its conidiogenous cells exhibit distinctive globular intumescence which differs from existing genera in Muyocopronaceae . Descriptions and illustrations of G. polychromus are provided with a key to asexual genera in Muyocopronaceae .
The monotypic genus Excipulariopsis, with type species E. narsapurensis, was established based on the emended generic characteristics of Excipularia narsapurensis. Excipulariopsis has non-cupulated superficial conidiomata arising directly from stroma surrounded by thick walled dark brown subulate setae. The conidia are dark brown, broadly fusoid, having thick septa and truncate base. Phylogenetic analyses using ITS, LSU, TEF1α and RPB2 sequences positioned Excipulariopsis allied to Speiropsis in the family Wiesneriomycetaceae, as a sister family to Tubeufiaceae within Tubeufiales. This study resolved a long-standing ambiguity about the phylogenetic status of this unique sporodochial setose hyphomycetes from India.
