Pyramimonadophyceae is a class of green algae in the division Chlorophyta. [1]
The Prorocentrales are a small order of dinoflagellates. They are distinguished by having their two flagella inserted apically, rather than ventrally as in other groups. One flagellum extends forward and the other circles its base, and there are no flagellar grooves. This arrangement is called desmokont, in contrast to the dinokont arrangement found in other groups. Accordingly, the Prorocentrales may be called desmoflagellates, and in some classifications were treated as a separate class Desmophyceae.
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.
The Fucales (fucoids) are an order in the brown algae. The list of families in the Fucales, as well as additional taxonomic information on algae, is publicly accessible at Algaebase.
AlgaeBase is a global species database of information on all groups of algae, as well as one group of flowering plants, the sea-grasses.
Pedinophyceae is a class of green algae in the division Chlorophyta.
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.
Chaetophorales is an order of green algae in the class Chlorophyceae.
Pseudoscourfieldiales is an order of green algae in the class Pyramimonadophyceae.
Pyramimonadales are an order of green algae in the Chlorophyta.
Botrydiaceae is a family of yellow-green algae comprising 13 species in three genera. It is the only family in the order Botrydiales.
Tilopteridales is an order of brown algae with isomorphic alternation of generations.
Ralfsiales is an order of crustose brown algae containing two families.
Erythrotrichia is a red algae genus in the family Erythrotrichiaceae.
Mamiellophyceae is a class of green algae in the division Chlorophyta.
Nephroselmidaceae is a family of green algae, the only family in the order Nephroselmidales and the class Nephrophyceae within the division Chlorophyta.
Syracosphaerales is an order of algae consisting of three families:
Palmariales is an order of marine algae. It includes the edible seaweed dulse.
