Morphology<\/h2>\n

Plate-like colonies, flat to slightly wavy, more or less square or rectangular (older colonies sometimes with irregular outline); flattened, plate-like colonies sometimes aggregate together into larger colonies; most colonies microscopic. Colonies may contain only a small number of cells, or more than 4,000 cells. Colonies are composed of a single layer of cells, with the cells arranged in perpendicular rows; cells may be densely packed or distant from one another. Colonial mucilage is colorless, fine, and typically has diffuse margins; cells of some species facultatively develop individual envelopes. Cells spherical to widely oval; if oval, then with the longer axis of the cell lying in the plane of the colony; hemispherical following cell division; (0.4)1.2-6.5(17) \u03bcm in diameter. Cells pale to bright blue-green, rarely reddish. Cells of several planktic species possess one or a few aerotopes in their centers; otherwise without aerotopes.<\/p>\n

Ecology<\/h2>\n

Species inhabit both freshwater and saline environments. In North American temperate regions, several species are common in the plankton and metaphyton of eutrophic to mesotrophic waters; other common species are metaphytic in mesotrophic lakes, ponds, and swamps.<\/p>\n
