The recent revisions of moss taxa of the Moss Flora of Russia with integrative taxonomy approach found a number of similar phytogeographical patterns. European species traditionally assumed as circum-Holarctic or at least Eurasian in distribution appeared to be confined to Europe, having eastern boundary of distribution within the European Russia. Examples are provided by Rhynchostegium riparioides, Polytrichum formosum, Schistidium apocarpum, Lewinskya speciosa, Ulota crispa, Hedwigia ciliata, Plagiothecium laetum. Eastern vicariants may be well segregated geographically (Polytrichum formosum/ P. densifolium, Hedwigia ciliata /H. mollis, Rhynchostegium riparioides / R. aquaticum s.l.) or have a considerable overlap, e.g. Lewinskya speciosa/L. elegans. Interestingly haplotypes of Neckera pennata complex often have coincident geographical limits: amphiatlantic, two amphipacific, circumboreal, South Chinese and two montane; among them only saxicolous N. oligocarpa has stable morphological differences and presumably may represent suite of cryptic or semi-cryptic species. Highly supported infraspecific groupings corresponding to geographical patterns were found in course of our molecular phylogenetic studies also in widespread species of Anomodon, Rhabdoweisiaceae, Amphidium. Thus, the overall diversity of mosses within the circumboreal region turns to be much higher than it was though before. Among found bryogeographical boundaries the western administrative border of the former USSR and boundary of the permafrost territory in continental climate of Asia seems are more prominent that thought earlier.
