Comment:— Myurella brevicosta J.X. Luo and P.C. Wu (1980: 125) is a notable species from Xizang, China. It is characterized by (1) slightly firm plants with loose branches, (2) small, ovate to oblong-ovate leaves with obtuse to round apex and contracted bases, (3) weakly forked, occasionally absent costae, and (4) thick-walled laminal cells. It was reduced to a synonym of Glossadelphus prostratus by Gao and Cao (1992). Our observation of the type of M. brevicosta shows that it is conspecific with Bryocrumia vivicolor (Broth. & Dixon) W.R. Buck (1987: 522), which is noted as growing on moist rocks, most along streams, seasonally (irregularly) submerged (Ma et al. 2016). Although G. prostratus resembles B. vivicolor, the former species can be separated from the latter in having acuminate perichaetial leaves and incurved capsules (Ma et al. 2016). Thus, we place M. brevicosta in synonymy with B. vivicolor.
Bryocrumia vivicolor has various leaf forms in different collections (Kim & Yamaguchi 2020). The leaves of Xizang plants are elliptic, much larger, and arrange closer, which are similar to those from Mt. Li (Taiwan) specimen (Kim & Yamaguchi 2020). Bryocrumia vivicolor is known in China from Yunnan (Redfearn et al. 1989, O’Shea & Buck 2001, Ma et al. 2016) and Taiwan (Kim & Yamaguchi 2020). As Myurella brevicosta becoming a synonym, a new provincial record in China, Xizang, is added for B. vivicolor.
