Abstract: During the course of a study on the resupinate Aphyllophorales of China in 1963-1965, a lot of specimens collected from 18 provinces in this country by colleagues of the Mycological Department of our Institute were examined by the present author. In this paper, 5 families, 20 genera and 67 species of resupinate Aphyllophorales are reported. Of which, 5 genera and 42 species are considered to be new records to China. Among these new records, l6 species had already been cited in the late Professor F.L. Tai's work entitled "Sylloge Fungorum Sinicorum" (1979), although no descriptions were provided. All new records, including the 16 species discussed above are briefly described for the first time in this paper. Keys to the families, genera and species, as well as synonyms and distribution of all species are given. Scanning electron microsco-pic photographs of some new records are also presented.
