Range extension of two xerophytic mosses in China based on molecular and morphological data

Feng, C., Kou, J., Zhang, G.-L. & Wang, Z. 2020. Range extension of two xerophytic mosses in China based on molecular and morphological data. – Herzogia 33: 300 –308.An abnormal morphotype of Grimmia crinitoleucophaea Cardot, a species widely known as G. poecilostoma Cardot & Sebille, has been found in Inner Mongolian typical steppe, and its identification confirmed based on molecular and morphological data. Its morphological variation and taxonomic status are also discussed. Didymodon canoae C.Feng, J.Kou & L.Feng, a species previously known only from its type location in Inner Mongolia, was discovered in Tibet which extends its distribution range to a high elevation region of southwest China. Diagnostic characters, differences compared to similar species, distributional remarks and photographs of the two species are provided.
