A new species of Emericella from Tibet, China

Emericella miraensis sp. nov. is described and illustrated. It was isolated from the alpine plant Polygonum macrophyllum var. stenophyllum from Tibet, China, and is characterized by ascospores with star-shaped equatorial crests. The new species is distinguished from other Emericella species with stellate ascospores (e.g., E. variecolor, E. astellata) by its violet ascospores and verrucose spore ornamentation. ITS and β-tubulin sequence analyses also support E. miraensis as a new species.
