Result of an extensive moss study of earlier nearly unexplored areas of the northeastern part of the Subpolar Urals, namely Khulga River Basin is presented. An annotated list of mosses is compiled based on the identification of 1200 specimens collected in the Khulga River Basin (60.45–65.20°N, 60.42–62.20°E). The river starts at the border between the Polar and Subpolar Urals and flows down southwards along the eastern slope of the Ural Mountains to the confluence with the Severnaya Sosva River near the village Saranpaul (Berezovo District, Khanty-Mansi Autonomous Area — Yugra). The list includes 210 moss species, of which 56 species are new to the Khanty-Mansi Autonomous Area — Yugra. Five species are new to the Urals: Didymodon perobtusus, Lewinskya iwatsukii, Schistidium frisvollianum, Sphagnum mirum, Warnstorfia tundrae. Further 9 species were found in the Subpolar Urals for the first time: Dicranum bardunovii, D. laevidens, D. schljakovii, Encalypta pilifera, Flexitrichum gracile, Grimmia elatior, G. tergestina, Orthotrichum hyperboreum, Sphagnum annulatum. The data on occurrence of many moss species, which were previously known from single finds in the mountainous part of the area, is significantly expanded. Ecology, phytocenotic preference and distribution of the recorded species are discussed. |
