Two new Cordyceps-like species, Perennicordycepszongqii and Purpureocilliumzongqii, isolated from a larva and soil, are introduced. Morphological comparisons and phylogenetic analyses based on multigene datasets (ITS, LSU, RPB2 and TEF) support the establishment of the new species. Moreover, new species in the families Polycephalomycetaceae and Ophiocordycipitaceae were introduced into Tiankeng and the valley for the first time. Further attention needs to be paid to the diversity of other Cordyceps-like fungi in the special eco-environment of the karst region.
Keywords: Cordyceps-like species; Ophiocordycipitaceae; Polycephalomycetaceae; morphology; phylogenetic analysis.
