Pyramimonadaceae is a family of green algae. [1] [2]
The following genera are considered valid:
Prasinopapilla is considered to have uncertain taxonomic status. [3] Schilleriomonas is a synonym of Cymbomonas . [4]
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 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.
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.
Microthamnion is a genus of green algae in the family Microthamniaceae.
Pseudochlorella signiensis is a species of green algae in the family Koliellaceae. Pabia signiensis, the only species in the genus Pabia, is regarded as a synonym. Pabia was sunk into Pseudochlorella in 2016.
Bambusina is a genus of freshwater green algae in the family Desmidiaceae. Bambusina is a cosmopolitan genus, typically associated with acidic and oligotrophic waters. Species of this genus, particularly B. borreri, have been reported in all continents except Antarctica.
Sykidion is a genus of green algae. Pseudoneochloris is a synonym of this genus. As of March 2022, Sykidion was the only genus in the family Sykidiacaeae, which was the only family in the order Sykidiales.
Chlorokybus is a multicellular (sarcinoid) genus of basal green algae or charophyte. It has been classified as the sole member of the family Chlorokybaceae, which is the sole member of the order Chlorokybales, in turn the sole member of the class Chlorokybophyceae. It grows on soil and rock surfaces, and is rare.
Cruoriopsis is a genus of non-corraline red algae. It has sometimes been considered a synonym of Cruoriella Crouan & Crouan or part of the larger genus Peyssonnelia.
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.
The Rivulariaceae are a family of cyanobacteria within the Nostocales in which the filaments (trichomes) are tapered from wider at the base to narrower at the tip.
