Abstract

Eight species of silica-scaled chrysophytes were identified by electron microscopy of phytoplankton samples from the newly opened Kis-Balaton Water Protecting Reservoir, Hungary. The composition of this flora of silica-scaled chrysophytes is charachteristic for eutrophic to hypertrophic localities. Most of the species are common and widely distributed, even cosmopolitan. The record of Chrysosphaerella annulata, which was recently described from Austria and has been recorded from widely separated places in the world, is interesting. This and three further species (Spiniferomonas trioralis, Synura petersenii and S. curtispina) are new to Hungary, while the others (Paraphysomonas vestita, Mallomonas acaroides, M. alpina, M. tonsurata) were recorded before mainly on the basis of light microscopy. Electron micrographs of the above species are presented in the paper. A checklist of all the previous records of scaled chrysophytes in Hungary is added as an Appendix. With 10 figures.
