Octogoniella is a genus of green algae, in the family Chlorococcaceae. It contains a single species, Octogoniella sphagnicola, found as an epiphyte on Sphagnum leaves. [1] It is a rarely recorded taxon. [2]
The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of unicellular algae found in freshwater and moist terrestrial environments, less common today than they were during the Proterozoic. The stated number of species in the group varies from about 14 to 26. Together with the red algae (Rhodophyta) and the green algae plus land plants, they form the Archaeplastida.
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.
Bryopsidella is a genus of green algae in the family Bryopsidaceae.
Arabicodium is a genus of green algae in the family Codiaceae.
Callipsygma is a genus of green algae in the family Udoteaceae.
Dicranochaete is a genus of green algae in the order Chaetopeltidales. It is the only genus in the family Dicranochaetaceae.
Sporocladopsis is a genus of green algae in the family Chaetophoraceae.
Apodochloris is a genus of green algae, in the family Chlorococcaceae.
Closteridium is a genus of green algae, in the family Chlorococcaceae.
Emergococcus is a genus of green algae, in the family Chlorococcaceae. It contains a single species, Emergococcus lucens. It is neustonic in fresh water.
Ferricystis is a genus of green algae, in the family Chlorococcaceae.
Neospongiococcum is a genus of green algae, in the family Chlorococcaceae.
Trochisciopsis is a genus of green algae, in the family Trebouxiaceae.
Chlorochytrium is a genus of green algae, in the family Chlorochytriaceae.
Palmodictyon is a genus of green algae in the family Radiococcaceae.
The Mesostigmatophyceae are a class of basal green algae found in freshwater. In a narrow circumscription, the class contains a single genus, Mesostigma. AlgaeBase then places the order within its circumscription of Charophyta. A clade containing Chlorokybus and Spirotaenia may either be added, or treated as a sister, with Chlorokybus placed in a separate class, Chlorokybophyceae. When broadly circumscribed, Mesostigmatophyceae may be placed as sister to all other green algae, or as sister to all Streptophyta.
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).
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.
