Abstract:
Collections of submerged wood in streams in Prachuap Khiri Khan Province, Thailand yielded three sporoschisma-like taxa. Morphological examination and phylogenetic analysis of LSU sequence data support the separation of two isolates as new species (S. palauense and S. longicatenatum) and the other as collection of S. hemipsila. The sexual morph (Melanochaeta) is again linked to the asexual genus Sporoschisma by molecular data. The new species are introduced with descriptions and illustrations and compared with the most similar species.

Abstract:
The Chaetosphaeriaceae are a diverse group of pigmented, predominantly phialidic hyphomycetes comprised of several holomorphic genera including Chaetosphaeria, the most prominent genus of the family. Although the morphology of the teleomorphs of the majority of Chaetosphaeria is rather uniform, their associated anamorphs primarily exhibit the variability and evolutionary change observed in the genus. An exception from the morphological monotony among Chaetosphaeria species is a group characterised by scolecosporous, hyaline to light pink, multiseptate, asymmetrical ascospores and a unique three-layered ascomatal wall. Paragaeumannomyces sphaerocellularis, the type species of the genus, exhibits these morphological traits and is compared with similar Chaetosphaeria with craspedodidymum- and chloridium-like synanamorphs. Morphological comparison and phylogenetic analyses of the combined ITS-28S sequences of 35 isolates and vouchers with these characteristics revealed a strongly-supported, morphologically well-delimited clade in the Chaetosphaeriaceae containing 16 species. The generic name Paragaeumannomyces is applied to this monophyletic clade; eight new combinations and five new species, i.e. P. abietinussp. nov., P. eleganssp. nov., P. granulatussp. nov., P. sabinianussp. nov. and P. smokiensissp. nov., are proposed. A key to Paragaeumannomyces is provided. Using morphology, cultivation studies and phylogenetic analyses of ITS and 28S rDNA, two additional new species from freshwater and terrestrial habitats, Codinaea paniculatasp. nov. and Striatosphaeria castaneasp. nov., are described in the family. A codinaea-like anamorph of S. castanea forms conidia with setulae at each end in axenic culture; this feature expands the known morphology of Striatosphaeria. A chaetosphaeria-like teleomorph is experimentally linked to Dendrophoma cytisporoides, a sporodochial hyphomycete and type species of Dendrophoma, for the first time.

Abstract:
A new species, Thozetella pinicola , was isolated from leaf litter of Pinus elliottii Engelm. in Hong Kong. This taxon is described and compared with existing species in the genus. It occurs on the substrate as creamy white sporodochia and has short black conidiophores. Morphological characters are typical of Thozetella and it most closely resembles Thozetella falcata , Thozetella gigantea and Thozetella nivea , but may be distinguished by its distinct microawns and different conidial size. To gain further taxonomic insight into the phylogenetic relationships of our new taxon and its allies, we sequenced and analysed 6 different regions of 3 genes (ribosomal DNA and protein coding genes: RNA polymerase II largest subunit (RBP2) and β-tubulin). Resulting phylogenies are compared with existing morphological information. Molecular data support the relationship between Thozetella species and the Chaetosphaeriaceae (Chaetosphaeriales, Sordariomycetes). In addition, we recovered a new phylogenetic lineage (or group) within the existing phylogenetic framework of Thozetella as previously proposed. In particular, there is a close association between T. pinicola and T. nivea, which is strongly supported. The affinities of these 2 newly sequenced taxa are discussed in light of morphological and molecular characters.

Full text
Abstract:
Zanclospora (Chaetosphaeriaceae) is a neglected, phialidic dematiaceous hyphomycete with striking phenotypic heterogeneity among its species. Little is known about its global biogeography due to its extreme scarcity and lack of records verified by molecular data. Phylogenetic analyses of six nuclear loci, supported by phenotypic data, revealed Zanclospora as highly polyphyletic, with species distributed among three distantly related lineages in Sordariomycetes. Zanclospora is a pleomorphic genus with multiple anamorphic stages, of which phaeostalagmus-like and stanjehughesia-like are newly discovered. The associated teleomorphs were previously classified in Chaetosphaeria. The generic concept is emended, and 17 species are accepted, 12 of which have been verified with DNA sequence data. Zanclospora thrives on decaying plant matter, but it also occurs in soil or as root endophytes. Its global diversity is inferred from metabarcoding data and published records based on field observations. Phylogenies of the environmental ITS1 and ITS2 sequences derived from soil, dead wood and root samples revealed seven and 15 phylotypes. The field records verified by DNA data indicate two main diversity centres in Australasia and Caribbean/Central America. In addition, environmental ITS data have shown that Southeast Asia represents a third hotspot of Zanclospora diversity. Our data confirm that Zanclospora is a rare genus.

Full text
Abstract:
The genera Menisporopsis, Multiguttulispora and Tainosphaeria (Chaetosphaeriaceae) are saprobes inhabiting decaying plant material. This study is based on an integrated morpho-molecular characterisation to assess their generic concepts and explore phylogenetic relationships. Menisporopsis is revealed as polyphyletic, and species with 1-septate conidia and synnemata growing unilaterally along the seta are placed in the new segregate genus Arcuatospora. Codinaea dimorpha and C. triseptata are shown to be congeneric with Multiguttulispora sympodialis, the type species. Two new combinations are proposed: M. sympodialis is found conspecific with M. dimorpha. The Tainosphaeria complex is resolved into three genera. We found that the morphological separation of three groups within the genus is consistent with phylogenetic relationships. Tainosphaeria s. str. is accepted with five species. Tainosphaeria aseptata and T. lunata are transferred to the newly erected Phialoturbella, whereas T. obclavata is revealed as conspecific with Phialogeniculata guadalcanalensis, reducing it to a synonym. A new genus Flectospora is erected for a chloridium-like fungus nested in the Tainosphaeria clade. Based on molecular evidence, we show that asymmetrical, scolecosporous ascospores are a unique teleomorphic characteristic among family members. Therefore, we propose new combinations for Chaetosphaeria hispida in Paragaeumannomyces and Ch. spinosa in the new genus Ericiosphaeria, both exhibiting this rare morphotype.

Abstract:
The genus Catenularia (Chaetosphaeriaceae) was reviewed, and its relationships with morphologically similar fungi were evaluated using molecular and morphological data. Eleven species are accepted, four of which have been verified with molecular DNA data. The correct epithet ‘cupulifera’ is proposed for the type species C. cupuliferacomb. nov. Four other combinations are proposed, namely C. catenulatacomb. nov., C. elsikiicomb. nov., C. minorcomb. nov. and C. novae-zelandiaecomb. nov.Catenularia is an uncommon fungus inhabiting mainly decaying bark, wood and bamboo culms of various hosts and shows a widespread geographical distribution. It is circumscribed for fungi with mononematous, macronematous, simple conidiophores with terminal monophialides, usually accompanied with capitate hyphae. The conidia are aseptate, brown, cuneiform to rounded-obconic with an angular outline, adhering in chains. The diagnostic values of taxonomic characteristics of capitate hyphae and conidia (i.e. colour, shape in transverse section, setulae and formation) at the generic level were evaluated. An account of morphology, taxonomy and phylogeny of species accepted in Catenularia is provided. Based on ribosomal DNA sequences, Chalarodes obpyramidatasp. nov., characterised by catenate, angular, hyaline conidia with apical setulae, is revealed as closely related to Catenularia. The new genus Fuscocatenulagen. nov. is proposed for catenularia-like fungi having pigmented conidia with protracted maturation and round outline, with two species accepted, F. submersacomb. nov. and F. variegatacomb. nov. A new species Nawawia antennatasp. nov. is introduced and Nawawia is compared with morphologically similar taxa.

Abstract:
Species of Kionochaeta are saprobes commonly associated with decaying plant materials. As a part of surveys on freshwater microfungi, Kionochaeta-like taxon was found on a submerged decaying twig at a rivulet in the protected forest area of Khao Kheow Open Zoo (KKOZ), eastern Thailand. This taxon is microscopically similar to Kionochaeta, but clearly differs by its accessory lateral setiform branches and sterile setae arising beside the conidiophores. Multi-locus phylogenies inferred from four combined loci (SSU, ITS, LSU and RPB2) demonstrated that this taxon clustered as a unique clade with Kionochaeta species (Chaetosphaeriaceae, Chaetosphaeriales). Therefore, we introduce this taxon as K. setosimplicia, and it is phylogenetically close to K. castaneae, K. ramifera and K. pughii. Kionochaeta setosimplicia is separated from K. microspora and K. spissa. In Kionochaeta clade 1, K. nanophora forms a basal taxon. Kionochaeta ivoriensis forms a distinct Kionochaeta clade 2 distant from other Kionochaeta.

Abstract:
During a mycological survey of freshwater hyphomycetes on submerged leaves in southwest China, a new species, Anacraspedodidymum submersum, was isolated. The new species A. submersum is characterized by having monophialidic conidiogenous cells with funnel shaped collarettes and globose or subglobose, aseptate and hyaline conidia. Morphologically, A. submersum is somewhat similar to A. aquaticum and A. hyalosporum in conidiophores and conidiogenous cells, but can be easily distinguished by its subglobose to globose and smaller conidia. Phylogenetic analysis of combined ITS and LSU sequences show that the new species of Anacraspedodidymum clustered together with the genus Thozetella in Chaetosphaeriaceae. A full description, illustrations and a phylogenetic tree showing the position of A. submersum are provided herein.
