Morphological variability of seven monoclonal populations of the planktonic coccoid genus Chroococcus, isolated mostly from reservoirs, fishponds and littoral substrata from localities in the Czech and Slovak Republics, but occurred all over the world, were studied experimentally under various combinations of nutrient concentration, light intensity, temperature, and water movement. Four clusters of ten studied strains designed originally as species of the genus Chroococcus were distinguished in the Neighbor Joining phylogeny tree based on 16S rRNA gene sequences. Cell morphology and the formation of colonies studied in experiments verified the existence of these four clusters. One of them verified a distant generic position of the genus Limnococcus, which could not be classified to the genus Chroococcus and was established as an independent genus.
