Of the genus Microcystis (Cyanobacteria, chroococales), M. wesenbergii is the easiest species to identify: the spherical cells are relatively large (5-8 µm) and are embedded in thick colorless homogeneous mucilage with clearly defined contours. It is generally less abundant in Lake Kinneret than M. aeruginosa and M. flos aquae.

Microcystis flos-aquae together with Microcystis aeruginosa is common in Lake Kinneret throughout the year, and blooming periodically. The cells at the border and at the center of Microcystis colony looks different by chlorophyll and gas vesicles concentrations. The specimen was sampled from the shore of the lake in March 2006.

Microcystis flos-aquae (Cyanobacteria, Chroococcales) is a together with Microcystis aeruginosa are common in Lake Kinneret throughout the year, occasionally forming blooms with surface scums in winter or spring. The individual cells in a M. flos-aquae colony are 3-4 um in diameter, the colony is spherical or lens-shaped, with varying degree of spacing between cells within a colony. The dark spots clearly showing in the individual cells in this picture are due to the reflection of light from the gas vesicles. A bunch of choanoflagellates are attached at the upper left side of the colony.
