Chroococcus cumulatus is a cyanobacterium in the family Chroococcaceae, found in freshwater and semi-aquatic habitats. Members of the genus Chroococcus are among the simplest organized cyanobacteria, consisting of spherical cells that divide by binary fission to form pairs or tetrads held together within layered gelatinous sheaths. Cyanobacteria are cosmopolitan prokaryotes that carry out oxygenic photosynthesis using pigments including chlorophyll a, phycocyanin, and phycoerythrin. Chroococcus species occur in diverse aquatic habitats ranging from standing freshwater bodies to damp soil surfaces, rock faces, and tree bark in humid environments. The genus has historically been characterized primarily on the basis of cell size, sheath structure, and colony organization, though molecular analysis has increasingly revealed cryptic diversity within morphologically defined groups. Chroococcus cumulatus has been documented from northern European freshwater habitats. As a microscopic prokaryote, it has not been assessed by the IUCN, and its ecological role centers on primary production at the base of aquatic food webs in its habitat.

Chroococcus prescottii is a species of cyanobacteria in the family Chroococcaceae, named in honor of the American phycologist Gerald Weber Prescott, who made major contributions to the study of freshwater algae in North America during the twentieth century. Like other Chroococcus species, it consists of spherical cells arranged in pairs or small groups within a gelatinous sheath matrix. Cyanobacteria of this genus are common inhabitants of freshwater lakes, bogs, and other aquatic environments across temperate and boreal regions. Chroococcus prescottii has been documented from North American and European freshwater localities. The species occupies the plankton or periphyton of its host water bodies, contributing to primary production through photosynthesis. In aquatic food webs, small cyanobacteria serve as food for herbivorous zooplankton such as cladocerans and copepods, linking primary production to higher trophic levels. The taxonomy of Chroococcus has been complicated by the variable expression of morphological characters under differing environmental conditions and by the recognition through molecular analysis that the genus as traditionally defined is polyphyletic. Chroococcus prescottii has not been assessed by the IUCN.
