Pseudodactylaria fusiformis sp. nov. was collected during an investigation of freshwater fungi along a north-south latitudinal gradient in the Asian region. Evidence for the new species is provided by morphological comparison and sequence data analysis. Pseudodactylaria fusiformis differs from other species in having hyaline conidiophores and fusiform, 0–1-septate hyaline conidia without a sheath. Phylogenetic analysis based on combined ITS and LSU sequence data was carried out to determine the phylogenetic placement of the species. Six Pseudodactylaria taxa clustered together and formed a monotypic clade representing the genus, and five species are well recognized. Pseudodactylaria fusiformis and P. camporesiana share a sister relationship and they are phylogenetically distinct species. A detailed description and illustration are provided, as well as the comparisons with similar taxa.

A New Species

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.

Two new species, Castanediellabrevis and C.monoseptata, are described, illustrated and compared with other Castanediella taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Castanediellabrevis can be distinguished from other Castanediella species by the short hyaline conidiophores and fusiform, aseptate hyaline conidia, while C.monoseptata differs from other Castanediella species by its unbranched conidiophores and fusiform, curved, 0–1-sepatate, hyaline conidia. Phylogenetic analysis of combined ITS and LSU sequence data was carried out to determine the phylogenetic placement of the species. A synopsis of hitherto described Castanediella species is provided. In addition, Castanediella is also compared with morphologically similar-looking genera such as Idriella, Idriellopsis, Microdochium, Neoidriella, Paraidriella and Selenodriella.

A New Species

A new species Alfaria avenellae, is described, illustrated and compared with other Alfaria species. Evidence for the new species is provided by morphological comparison and sequence data analyses. Alfaria avenellae can easily be distinguished from other Alfaria species by its distinct synnemata, long conidiophores (up to 350 μm) and pale green to dark green conidia. Phylogenetic analysis of combined LSU and ITS sequence data was carried out to determine the phylogenetic placement of this new species within the genus Alfaria and provide evidence to support the establishment of our new species.

The detailed descriptions and illustrations of the new species are provided, as well as the morphological comparison with similar taxa are discussed. Two strains of Neohelicomyces aquaticus and Tubeufia cylindrothecia are provided.

Freshwater Habitats

During our ongoing investigations of freshwater fungi in Thailand, three new chaetosphaeriaceous species, Chloridium aquaticum, Chloridium aseptatum and Dictyochaeta aquatica, were found on submerged wood in freshwater habitats. To determine their placement, a phylogenetic analysis of combined LSU and ITS sequence data was performed. Chloridium aquaticum is the only species having proliferating conidiophores and holoblastic conidiogenous cell in Chloridium. A detailed description and illustrations of the taxa is provided and phylogenetic relationship between the new taxa and their relatives are compared and discussed.

During a survey on diversity of freshwater fungi along a north-south latitudinal gradient in Asia, three fresh specimens of Minimelanolocus were collected from submerged wood in streams in northwestern Yunnan Province, China. Based on their distinct morphological features and phylogenetic analyses of combined ITS, LSU and SSU sequence data, Minimelanolocus nujiangensis and M. clavatus are described as new species and M. submersus was recollected from Yunnan, China. Illustrations and descriptions with notes of the three species are provided. This study increases the known diversity of Minimelanolocus and enriches freshwater fungal resources.

Greater Mekong Subregion

During our surveys of freshwater fungi on submerged wood in the Greater Mekong Subregion, a rhexodenticula-like taxon was collected, described and illustrated. The new collection is identified based on analyses of combined LSU, SSU, ITS and TEF sequence data, and morphological comparison with other Rhexodenticula species. According to the morphology and molecular analysis, our collection is not known before and hence, we introduce here as Rhexodenticula aquatica sp. nov. This species is characterized by macronematous, subcylindrical, unbranched conidiophores, polyblastic, terminal conidiogenous cells and fusiform, 3-septate, verruculose conidia, and schizolytic conidial secession. Rhexodenticula is referred to Sordariomycetidae genera incertae sedis due to its unstable phylogenetic placement in Sordariomycetidae.

Triadelphia fusiformis sp. nov. was collected during an investigation of freshwater fungi along a north-south latitudinal gradient in the Asian region. It differs from previously described Triadelphia species in having only one form of fusiform conidia. Phylogenetic analyses based on combined ITS and LSU sequence data indicate that T. fusiformis formed a distinct subclade among the species of Triadelphia. A detailed description and illustration are provided, as well as the comparisons with similar taxa. A checklist of accepted Triadelphia species is provided.

Decaying Wood

Conioscypha is an asexual morph genus placed in the family Conioscyphaceae. During our study of brown-spored hyphomycetes, a new taxon C. tenebrosa was found on decaying wood collected in Guizhou Province, China. The new species is characterized by having micronematous, hyaline conidiophores which are often reduced to conidiogenous cells, with a cup-shaped, percurrently developed, multi-collaretted phialide, and globose to subglobose, obovoid conidia with broadly rounded apex and subtruncate base. The phylogenetic analysis of combined LSU, SSU, ITS and RPB2 sequence data showed that isolates of C. tenebrosa are phylogenetically distinct from other species. Conioscypha tenebrosa sp. nov. is therefore introduced here with a description and morphological illustration. Taxonomic notes and a morphological comparison of Conioscypha species are provided.

A New Species

Colletotrichum sonchicola, sp. nov. from Sonchus sp. (dandelion tribe) in Forlì-Cesena Province, Italy, is introduced using morphological and molecular data. Combined phylogenetic analysis of ITS, GAPDH, CHS, ACT and TUB2 sequence data demonstrate that C. sonchicola is a distinct species within the dematium species complex. The new species is illustrated and compared with related taxa. This provides the first record of a Colletotrichum species from the genus Sonchus.
