Chlamydomonadales, also known as Volvocales, are an order of flagellated or pseudociliated green algae, specifically of the Chlorophyceae. Chlamydomonadales can form planar or spherical colonies. These vary from Gonium up to Volvox. Each cell has two flagella, and is similar in appearance to Chlamydomonas, with the flagella throughout the colony moving in coordination.
Tetradesmus lagerheimii is a green alga in the family Scenedesmaceae. It is also known by its synonym, Scenedesmus acuminatus.
Coelastrum is a genus of green algae in the Scenedesmaceae family. It is a common component of the phytoplankton in freshwater habitats such as ponds, lakes, waterfalls, and temporary pools of water, particularly eutrophic ones. The genus has a more or less cosmopolitan distribution, although some species appear to have more restricted geographical distributions.
Asterarcys is a genus of green algae in the family Scenedesmaceae. It contains a single species, Asterarcys quadricellularis, also spelled as Asterarcys quadricellulare.
