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.

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.

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.

We are currently studying lignicolous freshwater fungi in China. In this paper, we introduce two taxonomic accounts to the  family Amniculicolaceae in Pleosporales viz. Murispora aquatica sp. nov (from Yunnan) and a new record of Murispora fagicola (from Tibet). The conclusions were derived from both morphological comparisons and the results of phylogenetic analyses (concatenated ITS, LSU, SSU and TEF1-α sequence data). The new species is compared with other existing species of Murispora and comprehensive descriptions and micro-photographs are provided.

A survey of freshwater fungi on submerged wood in China and Thailand resulted in the collection of three species in Dictyocheirospora and four species in Dictyosporium including two new species in the latter genus. Morphological characters and phylogenetic analyses based on ITS, LSU and TEF1α sequence data support their placement in Dictyocheirospora and Dictyosporium (Dothideomycetes). An updated backbone tree is provided for the family Dothideomycetes. Descriptions and illustrations of the new taxa and re-collections are provided. Four new combinations are proposed for Dictyocheirospora.

During a survey of freshwater fungi in Guizhou Province, China, a collection from a submerged decaying twig in Baihua Lake was identified as a new species of Sporidesmium sensu lato based on morphological characters and phylogenetic analyses of combined LSU, SSU, ITS, TEF1α and RPB2 sequence data. Phylogenetic analyses supported its placement in Sordariomycetes but the fungus grouped distant from Sporidesmium sensu stricto, and its ordinal or familial position within the class remained inconclusive. Sporidesmium guizhouense sp. nov. is introduced with an illustrated account and notes on its taxonomy, phylogeny and systematic position are provided.

Two New Species

Lignicolous freshwater fungi represent one of the largest groups of Ascomycota. This taxonomically highly diverse group plays an important role in nutrient and carbon cycling, biological diversity and ecosystem functioning. The diversity of lignicolous freshwater fungi along a north-south latitudinal gradient is currently being studied in Asia. In this paper, we introduce two novel freshwater taxa viz. Tingoldiago hydeisp. nov. and T. clavatasp. nov. which were collected from freshwater substrates in Eastern Thailand. Morphological comparison based on the size of ascomata, asci and ascospores, as well as multi-gene phylogenetic analyses based on LSU, SSU, ITS and TEF1-α DNA sequences, supports their placement in Tingoldiago (Lentitheciaceae). Descriptions and illustrations of these two new species are provided.

Greater Mekong Subregion

A collection of lignicolous freshwater fungi in the Greater Mekong Subregion resulted in four interesting dematiaceous hyphomycetes with similar morphology. The taxa had sporodochial colonies, micronematous to semi-macronematous conidiophores and subglobose, ellipsoidal to broadly pyriform, 0–1-septate, dark brown to black conidia. Based on morphological characters and phylogenetic analyses of combined LSU, SSU, ITS and RPB2 sequence data, Parafuscosporella aquatica sp. nov., P. pyriformis sp. nov., Conioscypha tenebrosa and Vanakripa minutiellipsoidea are identified. Parafuscosporella aquatica and P. pyriformis cluster within Fuscosporellaceae (Fuscosporellales), while C. tenebrosa and V. minutiellipsoidea are placed within Conioscyphales. This is the first report on the phylogenetic placement of Vanakripa. Descriptions and illustrations of the new collections are provided.

Ancient Hybridization

Abstract—Doellingeria and Eucephalus form the earliest-diverging clade of the North American Astereae lineage. Phylogenetic analyses of both nuclear and plastid sequence data show that the Doellingeria-Eucephalus clade consists of two main subclades that differ from current circumscriptions of the two genera. Doellingeria is the sister group to E. elegans, and the Doellingeria + E. elegans subclade in turn is sister to the subclade containing all remaining species of Eucephalus. In the plastid phylogeny, the two subclades are deeply divergent, a pattern that is consistent with an ancient hybridization event involving ancestral species of the Doellingeria-Eucephalus clade and an ancestral taxon of a related North American or South American group. Divergence of the two Doellingeria-Eucephalus subclades may have occurred in association with northward migration from South American ancestors. We combine these two genera under the older of the two names, Doellingeria, and propose 12 new combinations (10 species and two varieties) for all species of Eucephalus.

Nomen Novum

In a recent monograph on the genus Rosellinia, type specimens worldwide were revised and re-classified using a morphological approach. Among them, some came from Pier Andrea Saccardo’s fungarium stored in the Herbarium of the Padova Botanical Garden. In this work, we taxonomically re-examine via a morphological and molecular approach nine different Roselliniasensu Saccardo types. ITS1 and/or ITS2 sequences were successfully obtained applying Illumina MiSeq technology and phylogenetic analyses were carried out in order to elucidate their current taxonomic position. Only the ITS1 sequence was recovered for Rosellinia areolata, while for R. geophila, only the ITS2 sequence was recovered. We proposed here new combinations for Rosellinia chordicola, R. geophila and R. horridula, while for R. ambigua, R. areolata, R. australis, R. romana and R. somala, we did not suggest taxonomic changes compared to the current ones. The name Rosellinia subsimilis Sacc. is invalid, as it is a later homonym of R. subsimilis P. Karst. & Starbäck. Therefore, we introduced Coniochaeta dakotensis as a nomen novum for R. subsimilis Sacc. This is the first time that these types have been subjected to a molecular study. Our results demonstrate that old types are an important source of DNA sequence data for taxonomic re-examinations.
