planktonic colony

Descrission:

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.
