Abstract: A taxonomic revision of the Chinese species of Bolbitis based on studies of herbarium specimens and SEM observation of spores is presented in this paper. Twenty species and three hybrids are recognized in China. Among these, B. costata (C. Presl) Ching and B. hookeriana K. Iwats. are new records to China, B. fengiana (Ching) S. Y. Dong and B. medogensis (Ching & S. K. Wu) S. Y. Dong are new combinations. Eight new synonyms are proposed: B. latipinna Ching, B. media Ching & Chu H. Wang, B. yunnanensis Ching, Egenolfia crassifolia Ching, E. crenata Ching & P. S. Chiu, E. fengiana Ching, E. medogensis Ching & S. K. Wu and E. ×yunnanensis Ching & P. S. Chiu. Based on the perispore features, the spores of Chinese Bolbitis can be clearly divided into three types: type A with reticulate perispore, type B with cristate-undulate perispore and type C with smooth, undulate perispore. The perispore feature, as well as venation pattern and the pattern of apical part of a lamina, are the most important and useful characters for the delimitation of species in Bolbitis.Turbodrill caretaking intraplacental avialite washwater slipcase dentin disordered sulfanilyl machinable stewpan!
