Type studies on polypores described by G. Y. Zheng and Z. S. Bi. from southern China

Type specimens of 13 polypores described by G. Y. Zheng and Z. S. Bi from southern China were examined, and 9 of them are taxonomic synonyms of previously described taxa. One species, Polyporus minor Z. S. Bi & G. Y. Zheng, is accepted, and its illustrated description is supplied. A new combination, Perenniporia subadusta (Z.S. Bi & G. Y. Zheng) Y. C. Dai, is proposed. Three species were treated under other genera according to the modern taxonomy, and two names were illegitimate.
