Abstract: In 1929, V. F. Brotherus published eight species and one form of Chinese Brachytheciaceae based on Handel-Mazzetti's collections from Hunan, Guizhou and Yunnan provinces of China during 1914～1918. The holotypes of all the taxa mentioned above were studied by the present authors. Three names are newly reduced to synonyms: Brachythecium subcurvatulum≡ Brachythecium velutinum ; Rhynchostegium gracilescens≡ Eu-rhynchium savatieri and Rhynchostegium obsoletinerve≡Herzogiella turfacea.
