Two new species of (Cordycipitaceae, Hypocreales) from the Mayao River Valley, Guizhou, China.

species have been often found in the forest habitat and rarely found in special karst eco-environments, such as Tiankeng, valleys and caves. In this research, eleven cordyceps specimens were collected from Mayao River Valley. A known species () and two new species ( and ) were established and described according to a multilocus phylogenetic analysis and morphological characteristics. Our results provide insight that the richness of species in karst eco-environments and further attention should be paid to entomopathogenic fungi in such habitats.
