During the study of continuous cropping obstacle of Ganoderma lucidum, an ascomycetes, designated WS058 was isolated from Lishui city, Zhengjiang Province. The pure culture was obtained by single mycelial isolation method. We used morphological characteristics and the phylogeny analysis of rDNA-ITS sequence to identify the taxonomic status of this fungus, and the results demonstrated that the strain WS058 was Xylogone ganodermophthora. It is the first record of this genus and species in China. In the paper, the detailed description and microscopic structure illustration were provided.
