Chlorogonium is a genus of green algae in the family Haematococcaceae. It was first described by Christian Gottfried Ehrenberg in 1837, with the type species Chlorogonium euchlorum; currently, around 30 species are accepted. They are found in freshwater habitats worldwide.
==Description== Chlorogonium consists of spindle-shaped or otherwise elongated cells, with two short, equal flagella at the anterior end of the cell. Each cell contains more than three contractile vacuoles scattered throughout the cytoplasm. There is a single chloroplast in the cell, which is parietal or spiral, filling most of the cell. Pyrenoids are normally present, but in some conditions (such as in photoheterotrophic medium), some species do not produce pyrenoids. At the center of the cell is a single nucleus. The chloroplast generally has a prominent reddish eyespot in the anterior of the cell.
