sp. nov., a new hyphomycetous fungus from freshwater habitats in China.

Background: Freshwater fungi, growing on submerged wood, can promote the degradation of organisms and the reuse of rotten wood energy and play key roles in freshwater ecosystems. Here, a new hyphomycetous fungus, , was isolated and identified from submerged wood samples collected in a small stream in Jiangxi Province, south-eastern China.

New Information: The new taxon was studied, based on morphological characters and phylogenetic analyses combined with LSU, ITS, and sequences data. was morphologically characterised by its pink colonies on PDA medium in prophase, macronematous, mononematous, solitary, brown, septate, unbranched, straight or slightly flexuous conidiophores with holoblastic, polyblastic, integrated, terminal, pale brown conidiogenous cells and cylindrical, narrowly clavate, broadly obovoid to cuneiform, 3-4-distoseptate, olivaceous brown or brown conidia with rounded apex. A phylogenetic tree was constructed, based on the combination of LSU, ITS, and sequences data.
