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.
