Chroococcus giganteus is a species of cyanobacteria in the family Chroococcaceae, notable for being among the largest-celled representatives of its genus, as indicated by the specific epithet. While cyanobacterial cells are generally microscopic, there is considerable variation in cell size within the genus Chroococcus, and giganteus refers to its relatively large cell diameter compared to other species in the group. Chroococcus cells are spherical to hemispherical, typically dividing by binary fission to form pairs or groups of two to four cells enclosed within layered mucilaginous sheaths. The photosynthetic pigments in the cells give them a blue-green to olive coloration. Chroococcus giganteus has been documented from freshwater and moist terrestrial habitats in various geographic regions. As a cyanobacterium, it contributes to primary production in its habitat and potentially to nitrogen cycling if it possesses nitrogen-fixing capacity. Taxonomic resolution within the genus Chroococcus remains challenging due to the limited morphological complexity of these organisms and the significant influence of environmental conditions on cell size and sheath development. The species has not been assessed by the IUCN.

Chroococcus turicensis is a species of cyanobacteria in the family Chroococcaceae, with the specific epithet turicensis referring to Turicum, the Latin name for the city of Zurich, Switzerland, suggesting that the species was first described or commonly documented from Swiss freshwater habitats. Chroococcus species are small, coccoid cyanobacteria occurring in pairs or tetrads within gelatinous sheaths in freshwater and moist environments. Chroococcus turicensis has been recorded from lakes and other freshwater localities in central Europe, including the alpine and pre-alpine lakes of Switzerland. Alpine and subalpine freshwater bodies are generally oligotrophic, and the cyanobacteria that inhabit them tend to be well adapted to low nutrient concentrations and clear, well-lit waters. The freshwater phytoplankton of Alpine lakes has been extensively studied due to the ecological and economic importance of these water bodies as drinking water reservoirs and indicators of environmental change. Chroococcus turicensis contributes to the diversity of the cyanobacterial component of such communities. Like all Chroococcus species, it is a prokaryote whose conservation status has not been assessed by the IUCN.
