ABSTRACT. A morphological and molecular phylogenetic study of Dicranum with elongate, porose distal laminal cells and costae with ridges on dorsal surface (sect. Dicranum) from Asian Russia revealed an unknown species. It is described as Dicranum baicalense sp. nova. It differs from the other species of the section Dicranum by having straight, homomallous leaves with two ridges on the dorsal side of costa, long and narrow upper laminal cells, and arcuate-cylindric, smooth capsules. A comparison of the new species with the representatives of the section Dicranum is provided. Dicranum baicalense occurs in southern Siberia (Republic of Buryatia and Zabaikalsky Territory) and the southern Russian Far East (Amur Province and Primorsky Territory). Morphological distinctions and distribution of D. japonicum Mitt. in Russia are also discussed.
