ABSTRACT

This paper summarizes the present knowledge of the of Ceriporiopsis () in China. Eleven species are found, and a key is compiled for the species so far recorded from the country. Among them, Ceriporiopsis jelicii (Tortic & A. David) Ryvarden & Gilb. is newly found in China, and description and illustration of this species are given according to the Chinese material.

Key words: Basidiomycota, polypore, .
