ABSTRACT. The status and distribution of Pohlia saprophila (Müll. Hal.) Broth. remained vague, as this species was not specially studied. Being described from the Central China, Gansu Province, it was treated as doubtful in the last edition of Flora of China. Pohlia saprophila is closely related to P. elongata, and its distinction from this species in dioicous sexual condition could be considered ambiguus, as dioicous plants occasioanlly occur in some populations of P. elongata as well. However, dioicous sexuality in Pohlia saprophila is stable and consistent with very dense growth of plants due to numerous rhizoids, and it distinction is also well supported by ITS sequence data. In addition to China, this species occurs in Mongolia, Kazakhstan, Kyrgyzstan, South Siberia (Altai and Transbaikalia) and extending eastward to Kamchatka. Another species, which was described as dioicous in this groups, P. viridis Lindb. & Arnell, is synonymized with P. elongata.
