The genus Leskea in Russia is represented by one widespread species, L. polycarpa Hedw. Records of L. gracilescens appeared to be erroneous. Analysis of nuclear ITS sequence data demonstrated that North American samples of L. gracilescens and L. obscura clearly differ from European and Asian populations in several characteristic substitutions. Anomalous morphology of plants from Yakutia and Amur Province is described and illustrated. Their distribution likely corresponds to a high and late floodings of big rivers, crossing permafrost areas.
