Morphology<\/h2>\n

Microscopic colonies, spherical to oval in shape; sometimes composed of subcolonies; surrounded by a fine, diffuse mucilage. Cells are held at the ends of thin gelatinous stalks, which radiate from the colony center; stalks are nearly pseudodichotomously branched (each stalk branches into two more stalks, each roughly equal in length and thickness); stalks usually widened towards the colony center, and may be confluent. Cells are held by the stalks at the periphery of the colony; are often somewhat radially displaced from one another, rather than forming one uniform peripheral layer; usually distant from one another, but if densely arranged on the colony periphery, then at least with small spaces between cells (compare to Gomphosphaeria<\/em>, whose cells remain joined together for a long period following division). Cells spherical to slightly radially elongated; 0.6-4.2 \u03bcm in length or diameter; pale blue-green, olive-green, or yellowish; two species have one to several central aerotopes.<\/p>\n

Ecology<\/h2>\n

Free-floating colonies, planktic in temperate fresh and brackish waters, especially in cold mesotrophic lakes.<\/p>\n
