AB In recent years, three rare cyanophytes, Microcystis botrys TEILING, M. novacekii (KOMÁREK) COMPÈRE and Radiocystis geminata SKUJA, appeared in great abundance in the plankton of eutrophic lakes and fishponds in Western Slovakia. During the summer they produced or contributed to a massive planktonic water bloom. The two Microcystis species exhibit some similarities with M. aeruginosa but differ by smaller, unperforated colonies with very densely aggregated cells. M. botrys is distinguished from M. novacekii (and from other species of the genus) by semiglobose or tubular gelatinous protuberances in the colonial mucilage. Colonies of R. geminata stand out by the radially oriented cells in the mucilaginous envelope.
