Abstract

In water bodies of the West Siberian Plain, 8 species of the genus Vaucheria (Vaucheriales, Xanthophyta) were previously known: Vaucheria dichotoma, V. geminata, V. hamata, V. schleicheri, V. sessilis, V. taylorii, V. terrestris, V. walzi. These species belong to sections Woroninia and Corniculatae. In 2013, for the first time in the West Siberian Plain, in the Omsk Region (the valley of the Uy River), fertile specimens of the species Vaucheria aversa of the section Tubuligerae were found, which was new to the studied territory. V. aversa was found in the forest phytogeographical belt in a location with temporary shallow-water ecotopes occupied by hydromacrophyte agglomerations dominated by Caltha palustris, Eleocharis palustris, Callitriche palustris, Vaucheria sessilis, Spirogyra hassallii.
