Morphological and phylogenetic analyses reveal two new species and a new record of (Amphisphaeriales, Apiosporaceae) in China.

The genus includes endophytes, pathogens and saprobes, with a wide host range and geographic distribution. In this paper, six strains isolated from diseased and healthy tissues of bamboo leaves from Hainan and Shandong provinces in China were classified using a multi-locus phylogeny based on a combined dataset of ITS, LSU, and , in conjunction with morphological characters, host association and ecological distribution. Two new species, and , and a new record of in China, are described based on their distinct phylogenetic relationships and morphological analyses. Illustrations and descriptions of the three taxa are provided, along with comparisons with closely related taxa in the genus.
