Morphology<\/h2>\n

Microscopic to macroscopic colonies; spherical, oval, lobate (having multiple lobes), elongate, or irregular in shape; sometimes composed of packet-like sub-colonies (Microcystis viridis<\/em> is a good example of this); sometimes clathrate (lattice-like or net-like; with distinct holes between elongated bands of cells; Microcystis aeruginosa<\/em> colonies at certain stages of development, for example). Cells irregularly arranged, either sparsely or densely. Colonial mucilage is fine and colorless; sometimes forming a wide border around cells; margins may be either diffuse or distinct; mucilage with a refractive outline in some species (for example, Microcystis wesenbergii<\/em>). Cells spherical, or hemispherical following cell division; 0.8-6(9.4) \u03bcm diameter; without their own individual envelopes; aerotopes present. Cell content is pale blue-green, but the presence of aerotopes causes the cells to look brown.<\/p>\n

Ecology<\/h2>\n

Free-floating in plankton; common bloom-former in eutrophic waterbodies.<\/p>\n
