These species belong to sections <em>Woroninia</em> and <em>Corniculatae</em>. 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 <em>Vaucheria aversa</em> of the section <em>Tubuligerae</em> were found, which was new to the studied territory. <em>V. aversa</em> was found in the forest phytogeographical belt in a location with temporary shallow-water ecotopes occupied by hydromacrophyte agglomerations dominated by <em>Caltha palustris, Eleocharis palustris, Callitriche palustris, Vaucheria sessilis, Spirogyra hassallii</em>.
