& M.S. Ignatov. The genus Thamnobryum (Neckeraceae,
Bryophyta) in Russia
Arctoa (2011) 20: 137-151
Five species of Thamnobryum are currently known
in Russia: T. alopecurum (Hedw.) Niewl. ex Gang., T. coreanum (Cardot) Nog. & Z. Iwats., T. neckeroides (Hook.) E. Lawton, T. subseriatum (Mitt. ex Sande Lac.) B.C. Tan and T. subserratum (Hook. ex Harv.) Nog. & Z. Iwats. Lectotype of Thamnobryum vorobjovii (Laz.) Ochyra is selected; this species is synonymized with T.
neckeroides; some collections identified by A.S. Lazarenko as T.
vorobjovii belong also to T. coreanum. Thamnobryum plicatulum
is excluded from the moss flora of Russia. Thamnobryum
alopecurum occurs in the Caucasus and the Kaliningrad Province, its
occurrence in NW European Russia and Russian Far East is not
confirmed. Thamnobryum neckeroides grows in Asiatic Russia,
including Russian Far East and southern Siberia; it is also
recorded in the Caucasus (Abkhazia) and the Carpatian Mts. (Ukraine) for
the first time. Other three species are known in the Russian Far East, mostly
in its southern part, T. coreanum and T. neckeroides were also collected in Kamchatka. A key for the
identification of these five species, their description, illustrations,
ecological and distributional data are provided.
