A new species, Didymodon liae J. Kou, X.-M. Shao & C. Feng, is described and illustrated from Dagzê County in south central Tibet of China. The new species is most similar to Didymodon australasiae (Hook. & Grev.) R.H. Zander, but differs in plants growing loosely in a thin turf, stems without hyalodermis and sclerodermis, margins recurved from just above the base to nearly the apex, laminal cells strongly bulging, mammillose, covered with simple or forked papillae, and costa with a layer of ventral substereids and differentiated laminal basal cells. The new species is contrasted with other similar species of the genus. Information on its distribution and ecology is also provided.
