Periplegmatium is a genus of green algae in the family Chaetophoraceae. [1]
The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of freshwater unicellular algae, less common today than they were during the Proterozoic. Only 15 species have been described, but more species are likely to exist. Together with the red algae (Rhodophyta) and the green algae plus land plants, they form the Archaeplastida. However, the relationships among the red algae, green algae and glaucophytes are unclear, in large part due to limited study of the glaucophytes.

Eustigmatophytes are a small group of eukaryotic algae that includes marine, freshwater and soil-living species.
The Trebouxiophyceae are a class of green algae, in the division Chlorophyta. Their circumscription within the green algae is not well established due to the need for more genetic studies at higher levels within the group.
Bryopsidales is an order of green algae, in the class Ulvophyceae.
Chaetophoraceae is a family of green algae in the order Chaetophorales.
Botryococcus is a genus of green algae. The cells form an irregularly shaped aggregate. Thin filaments connect the cells. The cell body is ovoid, 6 to 10 μm long, and 3 to 6 μm wide. Fossils of the genus are known since Precambrian times, and form the single largest biological contributor to crude oil, and are a major component of oil shales.
Bryopsidella is a genus of green algae in the family Bryopsidaceae.
Dictyosphaerium is a genus of green algae, in the family Chlorellaceae.
Neochloris is a genus of green algae in the family Neochloridaceae.
Pediastrum is a genus of green algae, in the family Hydrodictyaceae. It is a photoautotrophic, nonmotile coenobial green algae that inhabits freshwater environments.
Heterococcus is a genus of yellow-green algae in the family Heteropediaceae.
Trichosarcina is a genus of green algae in the order Ulotrichales. Filoprotococcus was once regarded as a synonym. However, Filoprotococcus is now considered valid in its own right. Trichosarcina is considered to be of uncertain validity.
Udotea is a genus of green algae in the family Udoteaceae.
Arabicodium is a genus of green algae in the family Codiaceae.
Pleurococcus is a genus of green algae in the family Chaetophoraceae that are spherical in shape with a thick cell wall to protect themselves against excessive water loss.
Rhexinema is a genus of green algae in the order Ulotrichales. Recent research has suggested that the genus Helicodictyon is a synonym of Rhexinema.
Acanthosphaera is a genus of green algae, in the family Chlorellaceae.
Acicularia is a genus of green algae in the family Dasycladaceae.
Filoprotococcus is a genus of green algae in the order Ulotrichales. It was once regarded as a synonym of Trichosarcina. However, it is now accepted as a genus in its own right, and Trichosarcina is considered taxonomically uncertain.
