Four new araneogenous species and a new genus in Hypocreales (Clavicipitaceae, Cordycipitaceae) from the karst region of China.

The karst region in southwestern China is one of the biodiversity hotspots in the world with rich fungal diversity but under-studied. Four fungal species belonging to (Clavicipitaceae) and (Cordycipitaceae) were isolated from dead spiders. Morphological comparisons, phylogenetic analyses and a PHI analysis based on multigene datasets support the establishment of these new species viz., , , , and are introduced. A new genus, , is proposed to accommodate , which is phylogenetically distinct from Our results revealed that further attention needs to be paid to the diversity of araneogenous fungi in the karst regions of southwestern China.
