ABSTRACT. A rheophytic moss from Yunnan superficially similar to Hygrohypnum was found to belong to the Symphyodontaceae, and is resolved in a position sister to the genus Symphyodon in phylogenies by all four studied DNA markers: nuclear ITS, chloroplast trnL-F and rps4 and mitochondrial nad5. It is described as a new genus and species, Rheoshevockia fontana Ignatov, W.Z. Ma & D.G. Long, as it is strikingly different from species of the mainly epiphytic genus Symphyodon. This is not a unique case where molecular phylogenetic studies reveal a close though unexpected relationship between epiphytic and rheophytic mosses.
