Abstract
Names within Chionoloma tenuirostre are evaluated for proper taxonomic position. A total of 20 names are treated as synonyms, among them, 10 are here synonymised for the first time (Hyophila acutiuscula, Leptodontium subintegrum, Oxystegus cylindricus var. filifer, Trichostomum angustifolium, T. fallax, T. fallax f. minutum, T. fragilifolium, T. prionodon, T. siamense and T. uncinifolium) and three names are excluded from the synonymy (Barbula wollei, Tortula cylindrotheca and Trichostomum burmense). In order to maintain nomenclatural stability, the typification of 12 names is discussed and lectotypes are designated.
