The morphology of the vegetative cells and zygospores of the collected samples is briefly described, the ecological conditions in the habitats are characterized, and photos of &lt;em&gt;Spirogyra daedalea&lt;/em&gt; (lateral conjugation), &lt;em&gt;S. dictyospora&lt;/em&gt; (ladder-shaped conjugation) and &lt;em&gt;S. rugulosa&lt;/em&gt; (ladder-shaped conjugation) are given. In total, in water bodies of the West Siberian Plain the authors found 16 species of the section &lt;em&gt;Conjugata&lt;/em&gt; (&lt;em&gt;Spirogyra bellis, S. crassa, S. daedalea, S. decimina, S. dictyospora, S. gracilis, S. hungarica, S. irregularis, S. maxima, S. mirabilis, S. neglecta, S. nitida, S. pellucida, S. rugulosa, S. setiformis, S. varians&lt;/em&gt;).
