Staurastrum is a genus of green algae, specifically of the Desmidiaceae. [1]
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.
Prasiolales is an order of green algae in the class Trebouxiophyceae.
Ulotrichales is an order of green algae in the class Ulvophyceae.
Caulerpaceae is a family of green algae in the order Bryopsidales.
Chlorellaceae are a family of green algae in the order Chlorellales.
Chlorocystidaceae is a family of green algae. It is the only family in the order Chlorocystidales. The family was formerly placed in the order Ulotrichales.
Carteria is a genus of green algae in the family Chlamydomonadaceae. Carteria are similar in morphology to the common genus Chlamydomonas and differ by having four, rather than two, flagella at the vegetative stage.
Chloromonas is a genus of green algae in the family Chlamydomonadaceae. It is closely related to the model green algae, Chlamydomonas, and traditionally has been distinguished mainly through the absence of a pyrenoid.
Marsupiomonas is a genus of green algae, containing a single species Marsupiomonas pelliculata.
Monomastix is a genus of green algae in the class Mamiellophyceae. It is the only genus in the family Monomastigaceae, which in turn is the only family in the order Monomastigales.
The Desmidiaceae are one of four families of charophyte green algae in the order Desmidiales (desmids).
The Gonatozygaceae are one of four families of Charophyte green algae in the order Desmidiales (desmids).
Genicularina is a genus of green algae, specifically of the Gonatozygaceae.
Staurodesmus is a genus of green algae, specifically of the Desmidiaceae.
Xanthidium is a genus of green algae, specifically of the Desmidiaceae.
Mesostigma is a genus of unicellular biflagellate freshwater green algae, with a single species Mesostigma viride, covered by an outer layer of basket‐like scales instead of a cell wall. As of February 2022, AlgaeBase classified it as the only genus in the family Mesostigmataceae, the only family in the order Mesostigmatales, the only order in the class Mesostigmatophyceae. It is now considered to be one of the earliest diverging members of green plants/algae (Viridiplantae).
