Samsoniella 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 (S.haniana) and two new species (S.duyunensis and S.vallis) were established and described according to a multilocus phylogenetic analysis and morphological characteristics. Our results provide insight that the richness of Samsoniella species in karst eco-environments and further attention should be paid to entomopathogenic fungi in such habitats.
Keywords: Entomopathogenic fungi; Sordariomycetes; morphology; phylogenetic analysis; valley.
