Description: Colonial species. Colonies tend to float near the surface in nutrient-rich fresh water and other low-salinity waters. Cells have no individual mucilaginous envelopes, but the colony is encased in a fine colorless mucus. Can produce toxins (microcystins), and dense blooms can be dangerous to aquatic ecosystems as well as animal and human health.
Cell Size: 2-3um
Distribution: cosmopolitan
Synonym: Polycystis aeruginosa
