Abstract

Freshwater fungi are highly diverse in China and frequently reported from submerged wood, freshwater insects, herbaceous substrates, sediments, leaves, foams, and living plants. In this study, we investigated two freshwater species that were collected from Yunnan and Guizhou provinces in China. Detailed morphological analysis complemented by multi-gene phylogenetic analyses based on LSU, SSU, ITS, RPB2 and TEF1-α sequences data revealed them to be two new saprobic species, namely Acrogenospora alangiisp. nov. and Conioscypha yunnanensissp. nov. in their asexual morphs. Additionally, Acrogenospora alangiisp. nov. is reported for the first time as a freshwater ascomycete associated with the medicinal plant Alangium chinense (Alangiaceae). Detailed morphological descriptions, illustrations and updated phylogenetic relationships of the new taxa are provided herein.
