Pleosporales is the largest order of Dothideomycetes. In recent years, systematics of Pleosporales have undergone considerable revisions. Dictyosporiaceae is one of the newly established families within this order proposed to accommodate holomorphic saprobic Dothideomycetes. Currently 18 genera are recognised in Dictyosporiaceae. The new species, Jalapriya aquaticum sp. nov. and J. apicalivaginatum sp. nov. were collected from freshwater habitats in Gansu and Yunnan Provinces, China, respectively and are introduced, based on morphology and molecular analysis of combined ITS, LSU, SSU and TEF1-α sequence data. We also recovered one fresh collection of Dictyocheirospora vinaya D’souza, Bhat & K.D. Hyde, which is a new record for China. Jalapriya aquaticum differs from extant species of Jalapriya in rows converging at the apex and apical cells with spherical-like appendages. Jalapriya apicalivaginatum differs from extant species of Jalapriya in having the rows of conidia mostly arranged in a plane. The phylogenetic analysis place the new collections within Dictyosporiaceae (Pleosporales). Descriptions and illustrations of Jalapriya aquaticum, J. apicalivaginatum and Dictyocheirospora vinaya are provided. A synopsis of characters of species of Jalapriya is also 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.

A New Species

A new species, Akanthomyces neocoleopterorum, which was isolated from an infected ladybug, is introduced. Morphological comparisons with extant species and DNA-based phylogenies from analysis of a multigene dataset support the establishment of the new species. It differs from other species by having mononematous and verticillium-like conidiophores, longer phialides, and mostly cylindrical conidia. Both the morphological identification and phylogenetic analysis of combined ITS, LSU, RPB1, RPB2 and TEF sequence data support A. neocoleopterorum as a new species in the genus Akanthomyces.

Two New Species

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.

This paper describes five sarcosomataceous samples collected from southwestern China and provides an updated two locus phylogeny of Sarcosomataceae. Two new species, Donadinia echinacea and Plectania sichuanensis, are described based on morphological and phylogenetic analyses. Donadinia echinacea is a dematiaceous hyphomycete with pleurogenous, guttulate conidia. Plectania sichuanensis is a cup-fungus distinguished by its ochre hymenium and ellipsoid ascospores with small multiple oil droplets. Phylogenetic analysis based on ITS and LSU sequence data using broad taxon sampling supports establishment of the new species along with eight distinct clades within Sarcosomataceae.

Two new hyphomycetes, Paradictyoarthrinium aquatica and P. hydei were collected and isolated from submerged wood and decaying wood in China and Thailand respectively. Morphologically, they line well with Paradictyoarthrinium in having superficial, gregarious, black, powdery fruiting bodies, macronematous conidiophores with unevenly dictyoseptate, muriform, subglobose to ellipsoidal dark brown conidia, but they differ from the other species in having short conidiophores. Phylogenetic analysis of combined LSU, ITS and RPB2 sequence data showed that six taxa of Paradictyoarthriniaceae, including the two new species, form a monotypic clade among the phylogenetically close families in Pleosporales with good support. Six isolates of Paradictyoarthrinium formed four distinct clades and represent four different species. Detailed descriptions and illustrations of the new species are provided, as well as the comparisons with related taxa.

Two New Species

In this third contribution involving new Cantharellus species from South Korea, two new species are introduced. In addition, we document a first report of the recently described Japanese Cantharellus anzutake outside of Japan based on identical ITS sequence data. Cantharellus citrinussp. nov. is introduced as a new member of subgenus Cinnabarini, to which the closely related Korean C. albovenosus and Chinese C. phloginus also belong. Cantharellus curvatussp. nov. is introduced as a new member of subgenus Parvocantharellus, in which the Korean C. koreanus was recently placed. The respective placements of the new taxa are significantly supported by a phylogenetic analysis of sequences from the transcription elongation factor (tef-1).

Helicascus species from submerged wood in aquatic habitats in northern Thailand were studied based on morphology and analysis of DNA sequence data. Descriptions and illustrations of H. elaterascus and a new species H. chiangraiensis are provided.  H. chiangraiensis is characterized by unilocular ascostromata, fissitunicate asci with a long, narrow and coiled endoascus, ascospores with 2–4 large refractive guttules. The phylogenetic analysis based on combined ITS, LSU and SSU sequence data placed the species in Morosphaeriaceae (Pleosporales).

The morphology and phylogeny of two new sessilid species, Zoothamnium weishanicum n. sp. and Epicarchesium sinense n. sp., two insufficiently known species, Zoothamnium arbusculaEhrenberg, 1831 and Zoothamnium hentscheliKahl, 1935, and a well-known species, Carchesium polypinum (Linnaeus, 1767) Ehrenberg, 1838, collected from freshwater habitats of China, were investigated. Zoothamnium weishanicum n. sp. is characterized by its inverted bell-shaped zooids, double-layered peristomial lip, alternately branched stalk, and two different-length rows in infundibular polykinety 3 (P3). Epicarchesium sinense n. sp. is recognized by its asymmetric-pyriform zooids, single-layered peristomial lip, conspicuous cortical blisters on the pellicle, dichotomously branched stalk, and P3 containing one short inner row and two long outer rows. Based on previous and newly obtained data of the three known species, improved diagnoses and redescriptions are provided including, for the first time, data on the infraciliature of Z. arbuscula and Z. hentscheli. In addition, we analyzed the phylogeny of each species based on SSU rDNA sequence data.
