ABSTRACT. The list of mosses known for Magadan Region includes 434 species. It is compared to moss floras of other regions in the Russian Far East. It is shown that in the north of the Russian Far East, Magadan Region is characterized by a heightened diversity of mosses along with Kamchatka and Beringian Chukotka; the greatest similarity in the moss flora is observed with these same regions. The compiled summary table of species clearly demonstrates the latitudinal distribution of moss species in the Russian Far East and the distribution by the floristic regions within the Magadan Region. As a result of sorting the summary table of species lists, in the moss flora of Magadan Region three large groups of species differing in their predominant distribution in the Far East were revealed: “cross-cutting”, “northern” and “southern”. The former account for approximately 40%; the “northern” and “southern” groups have a comparable number of species. More than half of “southern” species in Magadan Region are at the northern limit of their distribution in the Far East. The locations of the “southern species” are concentrated in the Okhotsk District. A list of species that can be found in future is provided.
