Abstract
Dicranodontium tenii Broth. & Herzog in Herzog (1925: 150), initially described based on a specimen collected from Yunnan Province, China, was later suggested by Frahm (1997) to be identical to Dicranum hamulosum Mitten (1891: 156). However, the detailed morphological descriptions and excellent illustrations of these two species, based on the type specimens provided by Noguchi (1987) and Gao (1994) respectively, offer convincing evidence of their distinctions. For instance, Dicranum hamulosum lacks differentiated epidermal cells on the ventral side of the costa, while they are well-differentiated in Dicranodontium tenii (Noguchi 1987; Gao 1994).
