Abroteia is a genus of red algae. The type species for this genus is Abroteia orbicularis J.Agardh.
Pedinellales is a group of single-celled algae found in both marine environments and freshwater.
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.
AlgaeBase is a global species database of information on all groups of algae, as well as one group of flowering plants, the sea-grasses.
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.
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.
Chaetomorpha is a genus of green algae in the family Cladophoraceae. Members of this genus may be referred to by the common name sea emerald.
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.
Rhexinema is a genus of green algae in the order Ulotrichales. Recent research has suggested that the genus Helicodictyon is a synonym of Rhexinema.
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.
Pyrenomonas is a genus of cryptomonad.
Oxyrrhis is a genus of dinoflagellates. It includes the species Oxyrrhis marina.
Nemoderma is the only genus in the family Nemodermataceae and order Nemodermatales of the brown algae. The genus contains only a single species, Nemoderma tingitanum.
Vaucheria is a genus of Xanthophyceae or yellow-green algae. It is one of only two genera in the family Vaucheriaceae. The type species of the genus is Vaucheria disperma.
Erythrotrichia is a red algae genus in the family Erythrotrichiaceae.
Perkinsidae is a family of alveolates in the phylum Perkinsozoa, a sister group to the dinoflagellates.
Hapalidiaceae is a family of red alga belonging to the order Corallinales.
