ABSTRACT. The genus Philonotis in Russia includes two species with a subcontinuous holarctic distribution, P. fontana (Hedw.) Brid. and P. tomentella Molendo, one holarctic highly disjunctive species, P. marchica (Hedw.) Brid., three mainly European and western Asian species, P. calcarea (Bruch et al.) Schimp., P. rigida Brid. and P. seriata Mitt., and one mainly SE Asiatic and African species, P. falcata (Hook.) Mitt. Philonotis capillaris Lindb. has a disjunct distribution from western Europe to the Caucasus area, and in western North America through the Aleutian Islands to Russian Far East. P. yezoana Besch. & Cardot is known in addition to Japan and Korea from North and South Far East regions of Russia, and P. americana Dism. ranges from the Kuril Islands and Kamchatka to Western North America. Only a few specimens from European Russia can be referred to P. caespitosa Jur. A key to the species is given, they are illustrated and their taxonomy is discussed. The total ranges of taxa based on specimens studied, previous revisions and checklists and floras are given. Some erroneous reports are corrected and correct reports are confirmed. DNA studies (nrITS1-2 and cp trnL-F) show distiction of sect. Philonotis and sect. Philonotula, however P. capillaris is resolved within the former one. ITS analysis supports the distinction of P. caespitosa and P. tomentella from P. fontana, but the latter species appears to be paraphyletic.
