Genera[1]
See text.

The Chlorococcaceae consists mostly of coccoid (single, nonmotile) cells with one parietal or central chloroplast and one or multiple nuclei. The chloroplast contains a single pyrenoid surrounded by a starch envelope. The cell envelope may thicken with age and develop into a mucilaginous stalk in some species.^[2] Reproduction consists of zoospores with a cell wall; after they stop swimming, the zoospores retain their shape.^[2]

The family Chlorococcaceae is currently under taxonomic revision. As currently circumscribed, the type genus Chlorococcum is polyphyletic.^[2] The type species, Chlorococcum infusionum, is a member of the clade Moewusinia.^[3]
