Verruconis panacis sp. nov., an endophyte isolated from Panax notoginseng.

An endophytic strain (designated as strain SYPF 8337T) was isolated from the root of 3-year-old Panax notoginseng in Yunnan province of China. Strain SYPF 8337T grew slowly and formed pale brown to brown colonies. Phylogenetic analyses indicated that strain SYPF 8337T was placed in the Verruconis clade. Different from other Verruconis species, strain SYPF 8337T produced four-cell conidia. Furthermore, strain SYPF 8337T is the first fungus isolated as an endophyte of P. notoginseng in the genus Verruconis. Combined with the morphology and molecular analyses, a new species named Verruconis panacis sp. nov. is proposed.
