ABSTRACT

This is the first electron microscopy study of Bacillariophyta, a major component of Lake Kronotskoye phytoplankton, which revealed more than 80 taxa of diatoms. Among the 80, two species are new for the flora of Russia (Cavinula thoroddsenii (Foged) Lange-Bert. and Navicula jentzschii Grunow), and 10 forms were identified only to the genus. Genera Cymbella Agardh,, Pseudostaurosira Williams and Round, Gomphonema Ehrenb., Planothidium Round and Bukht. and Navicula Bory are the richest in species. Pennate (Asterionella Hassall) and centric (Aulacoseira Thw., Handmannia M. Perag.) diatoms represented the dominating species of phytoplankton.
