Westerdykella aquatica, isolated from rice field mud and as an endophyte from Acorus calamus, is described as a new species. The fungus is characterized by its globose cleistothecia, globose to subglobose, persistent, 8-spored asci, and cylindrical, 3-septate, light brown ascospores. A phylogenetic tree based on ITS, LSU, and β-tubulin sequences was constructed to infer the phylogenetic relationship between W. aquatica and other Westerdykella species in the genus. The new species was found to produce phytase, an important enzyme to release organic phosphorus in the soil.
