ABSTRACT. Leptodictyum mizushimae (Sakurai) Kanda (= Hygrohypnum mizushimae Sakurai), a rare East Asiatic species, known from Japan, Kuril Islands and Kamchatka, is studied by three molecular markers, including nuclear ITS, chloroplastic rps4 and mitochondrial nad5, and all of them indicate its affinity with Climaciaceae, despite lacking morphological similarity: plants are not dendroid and stem lacks any paraphyllia-like structires. A new genus, Limnohypnum is described to accomodate this species. Morphological description and illustrations are provided.
