Abstract
In the waterbodies of different types of the steppe zone of the Southern Urals, 19 taxa of silica-scaled Chrysophyceae belonging to the orders Chromulinales and Paraphysomonadales have been recorded. Among them, 16 taxa of the infrageneric rank were recorded for the first time for the studied territory; two species (Lepidochromonas cancellata and Polylepidomonas vacuolata) are new to the flora of Russia. New localities have been revealed of four species rare in the flora of Russia: L. poteriophora, L. stelligera, L. subrotacea, and Paraphysomonas caelifrica. For each discovered taxon, data on its morphology, locality, and distribution are provided. All findings are illustrated with microphotographs taken using scanning electron microscopy.
