Abstract:Type materials of Apomarsupella verrucosa (Nichols.) Vana from Yunnan, China and Gymnomitrion papillosum Kitag. & S. Hatt. from Nepal were studied. Detailed comparisons of the type specimens reveal that the two species are con-specific. Therefore, Gymnomitrion papillosum was reduced to synonym of Apomarsupella verrucosa.
