Multi-gene phylogenetic analyses revealed two novel species and one new record of (Pleosporales, Dictyosporiaceae) from China.

The rotting wood in freshwater is a unique eco-environment favoring various fungi. During our investigation of freshwater fungi on decaying wood, three hyphomycetes were collected from Jiangxi and Guangxi Provinces, China. Based on the morphological observations and phylogenetic analysis of a combined DNA data containing ITS, LSU, SSU and sequences, two new species, and , as well as a new record of , were introduced. Additionally, a comprehensive description of the genus with both morphological and molecular data was first provided.
