Coccolithus is a genus of unicellular haptophytes.
The species in this genus include: [1]
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 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.
Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts. Depending on the treatment of the genus Nitellopsis, living (extant) species are placed into either one family (Characeae) or two. Further families are used for fossil members of the order. Linnaeus established the genus Chara in 1753.
Navicula is a genus of boat-shaped diatom algae, comprising over 1,200 species. Navicula is Latin for "small ship", and also a term in English for a boat-shaped incense-holder.
Eustigmatophytes are a small group of eukaryotic forms of 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.
Chlorellaceae are a family of green algae in the order Chlorellales.
Hormotila is a genus of green algae in the family Chaetophoraceae.
Trentepohlia is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae, living free on terrestrial supports such as tree trunks and wet rocks or symbiotically in lichens. The filaments of Trentepohlia have a strong orange colour caused by the presence of large quantities of carotenoid pigments which mask the green of the chlorophyll.
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.
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.
Pyrenomonas is a genus of cryptomonad.
Chorda is a genus of thalloid brown algae. It is the only genus in the family Chordaceae. Its members are known by a number of common names including: mermaid's fishing line, tsurumo, ruálach, doruithe briain, sailors' laces, sea laces, mermaids line, roccálach, ruadhálach, gemeine meersaite, bootlace weed, seatwine, zottige meersaite, dead men's ropes, mermaid's tresses, cat gut and sea lace.
Erythrotrichia is a red algae genus in the family Erythrotrichiaceae. In Iceland, E. carnea is red listed as a vulnerable species (VU).
Perkinsidae is a family of alveolates in the phylum Perkinsozoa, a sister group to the dinoflagellates.
Kiitoksia is a genus of aquatic protist. The taxonomic position of the genus is still uncertain and it has not found a robust location in any subgroup.
Chrysomerophyceae is a monotypic class of photosynthetic heterokont eukaryotes.
