This scanning electron microscopy study of phytoplankton and microfitobentos from the Pisanets Lake (Republic of Karelia, Russia) has revealed a small-sized diatom species, Chamaepinnularia vyvermanii, rare to the flora of Russia. Differences in the variability range of the number of striae in 10 µm from the original description and literature data allow the authors to refine the description of this species. New data on the location clarify range of C. vyvermanii.
