Abstract
As a result of taking water samples in spring 1999, 26 species of silica-scaled chrysophytes were found in the Kis-Balaton Reservoir I, one of the most remarkable aquatic habitats in Hungary. From them, 23 have been identified with certanity, two were questionable and two were identified to genus level. 12 species are new to Hungary and 19 species had not been found in Kis-Balaton before. Most of the species are widely distributed, occuring mainly in eutrophic waters. The most abundant species were Paraphysomonas vestita, Synura petersenii and Mallomonas alpina, all three widely distributed, cosmopolitan species. Beside these, Mallomonas cratis and Mallomonas acaroides were found to be common members of the vernal flora of silica-scaled chrysophytes in Kis-Balaton. Mallomonas pseudocratis has been found only in a few places in the world, while Mallomonas alata and Mallomonas parvula have bipolar distribution
