Twenty-three strains of Chrysosporium were isolated from soil samples in different provinces of China. Phylogenetic analyses of ITS sequence data showed that these strains comprised nine new species and four already known species. The new species could be also distinguished from related species by their morphology. The results of phylogenetic and morphological analyses confirmed the nine new species of Chrysosporium. Descriptions and illustrations of these new species are provided.
