Species

Parachlorella is a genus of green algae in the order Chlorellales.[2] The genus Parachlorella is more or less indistinguishable from the similar genus Chlorella using morphological features alone; the two genera differ genetically, and can be identified using their 18S ribosomal RNA.[1]

Parachlorella consists of solitary, egg-shaped to spherical cells, sometimes covered in a gelatinous layer. The chloroplast is parietal and contains a broadly elliptical pyrenoid sheathed in grains of starch. Reproduction occurs through autospores. It is found in freshwater habitats, or soil.[1]
