Molecular phylogenetic studies revealed among collections from the Russian Far East an undescribed species of the genus Brachythecium. Morphological distinctions of B. amurense sp. nov. disagree with any species closely related according to the analysis of the nuclear ITS, the marker explored in most studied species of the genus. The fact that such large and conspicuous plant remained undiscovered indicates still incomplete knowledge of mountain moss flora of the Russian Far East and calls for more efforts for its exploration.
