Four New Endophytic Species Isolated from Three Species in Guizhou, China.

Endophytic fungi isolated from medicinal ferns serve as significant natural resources for drug precursors or bioactive metabolites. During our survey on the diversity of endophytic fungi from species (a genus of medicinal ferns) in Guizhou, was observed as a dominant fungal group. In this study, seven strains, representing four new species, were obtained from the healthy plant tissues of three species-. , . and . . The four new species, namely , . , . and . , were described in detail with color photographs and subjected to phylogenetic analyses using combined LSU, ITS, TEF1-α, and TUB2 sequence data. This study also documented three new hosts for species.
