Proposed synonyms in Cyathus

Abstract

Based on the morphological analyses of 48 taxa of Cyathus, including 30 type specimens, three Cyathus species were found to represent synonyms of existing species. Cyathus cheliensis, C. gansuensis and C. megasporus are herein accepted as synonyms of C. limbatus, C. pygmaeus and C. poeppigii, respectively. The latter three species are redescribed and illustrated.
