Pohlia tundrae was formerly described from North America, and subsequently was found also in Central Europe, Russian Far East and northern West Siberia. Recently, we discovered this species in Tibet, China. In this paper, morphological characteristics of P. tundrae are described; the photographs, habit, global distributions are provided; and morphological comparison of it with the similar species are discussed. The voucher specimen is deposited in the herbarium of China Agricultural University (BAU).
