The article generalizes data on the species diversity of the genus Spondylosium Brebisson ex Kutzing representatives in waterbodies of West Siberia, their distribution over zones and subzones. At present, 8 species and intraspecific taxa of the order Desmidiales are known in the region. These family representatives are mosaic spread throughout the territory of West Siberia. The largest numbers of taxa (5) are found in middle taiga, 1 and 3 taxa – in southern and northern taiga, respectively, from 2 to 4 taxa – in other zones. No species is recorded in the steppe zone. 6 species (7 taxa) of this genus are identified in lakes of diverse types, 4 species are known in streams, 2 species – in mires and temporary waterbodies. The analysis of the species confinement to environmental conditions has shown that the genus representatives can serve as indicators of acidic and slightly mineralized water. Indifferents (6 taxa) predominate as mineralization indicators, acidophiles (6 taxa) prevail among pH indicators.
