Abstract
Scanning electron microscopy studies of modern materials on phytoplankton from Lake Erie allowed the discovery of new for the lake’s flora centric diatoms of specific and generic rank (11), updating systematic position of some species and varieties and broadeninig of Centrophyceae taxonomic spectrum in this lake up to 44 species and 11 genera. The appearance of Cyclotella ocellata – Stephanodiscus niagarae complex in the phytoplankton points to a decrease in the lake’s trophic level.
