The genus Otidea was recently monographed and studied phylogenetically, but knowledge of the diversity and distribution of Otidea species in China is fragmentary. In this study, collections from China were examined morphologically and included in phylogenetic analyses. Using LSU, TEF1-α, and RPB2 new species were placed within previously recognized clades in the genus. The results agree with both Genealogical Concordance Phylogenetic Species Recognition (GCPSR) and genetic divergence as previously reported. Three new species, Otidea hanseniae, Otidea korfii and Otidea purpureogrisea are recognized based on phylogenetic reconstruction using ITS, LSU, TEF1- α and RPB2. Comments on some incompletely known species are added. With the discovery of these three new species, the genus Otidea in China proves to be more diverse than previously recognized.
