Abstract

A new species, Stachylidium chayuense, was isolated from a dead branch of an unidentified plant in the Chayu County, Xizang Autonomous Region, China. Phylogenetic analysis based on multi-locus (ITS, LSU, tef-1α, and rpb2) revealed that S. chayuense is closely related to S. pallidum. However, S. chayuense can be distinguished from S. bicolor and S. pallidum by its simple, unbranched conidiophores with a greater number of whorls of conidiogenous cells. The integration of morphological observations and molecular data strongly supports the establishment of the new species.
