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.

Chroococcus turgidus, (Cyanobacteria, Chroococales), from Lake Kinneret pelagic waters, April 2006, showing 2 daughter cells after division by simple binary fission â as characteristic for most Chroococcales species. This species is common in the plankton of Lake Kinneret throughout the year. Usually there are 2 â 8 cells in a colony. Clearly delimited colorless mucilaginous envelopes surround the individual cells following their contours, and the entire colony. Cell diameter: 8 â 11 µm.

Filamentous blue green algae with several morphologies, all lack a mucus sheath, glide and had no evident heterocysts (differentiated cells), and are probably (though not certainly) assignable to Oscillatoria. Phase contrast.

Filamentous cyanobacterium, unidentified, found as one of several cyanobacterial epibionts on the leaves of the moss Hygrohypnum, a site which seems to be a focus for nitrogen fixation. Differential interference contrast.

Intertwined filaments of cyanobacteria grow together to form a microbial mat.
-
This image of cyanobacteria shows how the filaments are made up of many disc-shaped cells joined end to end. Although all are the same species, the colors of the filaments vary. This can cause mats to have regions of different colors, even when they are formed by the same species

Merismopedia (mer-is-mo-pea-dee-a) is a blue-green alga or cyanobacterium (blue-green alga). The genus is distinguished by the square-packed pattern of the coccoid cells. It is common in sediments, but the number of cells which occur in a colony may vary from only a few to thousands. As a cyanobacterium, the photosynthetic pigments are located throughout the cytoplasm. Differential interference contrast

It is common in sediments, but the number of cells which occur in a colony may vary from only a few to thousands. As a cyanobacterium, the photosynthetic pigments are located throughout the cytoplasm. These can be seen if the cells are illuminated with ultra-violet light and then the distribution of the pigment detected by the resulting fluorescence. Fluorescence microscopy.
