ABSTRACT. Systematics of several species of Bryum is discussed, with the special attention to groups where the species concept was considerably expanded by the recent suggestions of Holyoak. The observations based on material from Russia support the traditional, more narrow understanding of: (1) Bryum archangelicum and Bryum amblyodon; (2) Bryum purpurascens and Bryum arcticum; (3) Bryum calophyllum and B. axel-blyttii. Rare species, B. teres and B. sibiricum are commented, and B. planiusculum is synonymized with B. turbinatum. New records of Bryum species for some provinces of Russia are also provided.
