Complex algological and hydrochemical studies were performed in July 2017 at the mouths of Upper Angara and Kichera rivers, as well as three mouths of Angara-Kichera estuary — Dushkachanskoye, Srednee and Dagarskoye, which supply water to Lake Baikal. The species diversity of scaled chrysophytes was studied via scanning and transmission electron microscopy. A total of 31 species and intraspecific taxa were detected: Chrysosphaerella — 1; Paraphysomonas — 2; Spiniferomonas — 8; Mallomonas — 14; Synura — 6. As a result, the list of scaled chrysophyte species in the Baikal region was extended by 3 taxa and currently includes 76 species and intraspecific taxa, thus making its diversity of scaled chrysophytes the highest in the world.
