A new species, Stephanonectria ellipsoidea, was isolated from decaying fruit in Kunming City, Yunnan Province, China. It is characterized by pale orange colonies, densely clustered, irregularly branched conidiophores, cylindrical phialides, and hyaline, ellipsoidal conidia. Its morphology fits well with the generic concept of Stephanonectria. This species is closely related to S. keithii based on phylogenetic analysis of concatenated LSU and ITS sequences. The combination of morphological observation and molecular data supports the erection of the new species.
