Chiloscyphus sikkimensis(Geocalycaceae,Hepaticae),New to Mainland of China

Chiloscyphus sikkimensis(Steph.) J.J. Engel & R.M. Schust. (Geocalycaceae,Hepaticae),discovered from Yunnan,is reported here as new to mainland of China. This species is characterized as leaves obliquely to subtransversely inserted on stem,adaxially convex,ovate with entire,obtuse or retuse; and underleaves often connate with adjoining leaves at their base on one or both sides,cordate to reniform with obtuse to retuse apex. Heteroscyphus acutangulus (Schiffn.) Schiffn. from Taiwan is actually C. sikkimensis and should be excluded from Chinese bryoflora.
