Abstract

As a result of studying samples from ephemeral water bodies of the Scientific Experimental Station Otradnoe, located in northwestern European Russia, four species of silica-scaled chrysophyte algae new to the Leningrad Region were recorded: Mallomonas insignis, Synura asmundiae, S. bjoerkii (the second record to Russia) and S. macracantha (the third record to Russia). This is the first study of chrysophyte algae in this locality that was done using the electron microscopy method. The article provides descriptions, data on distribution in Russia, and original micrographs for each species.
