Monotypic algae genera

Noctiluca is a genus of dinoflagellates in the family Noctilucaceae. Its only species is Noctiluca scintillans, a marine species that can exist in a green or red form, depending on the pigmentation in its vacuoles. It can be found worldwide, but its geographical distribution varies depending on whether it is green or red. This unicellular microorganism is known for its ability to bioluminesce, giving the water a bright blue glow seen at night. However, blooms of this species can be responsible for environmental hazards, such as toxic red tides. They may also be an indicator of anthropogenic eu

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. It is the only known genus in the class Mesostigmatophyceae (and thus, the only genus in the family Mesostigmataceae and the order Mesostigmatales).

Zoochlorella (: zoochlorellae) is a colloquial term for any green algae that lives symbiotically within the body of an aquatic invertebrate animal or a protozoan.

Compsopogon caeruleus, known as staghorn algae, is a species of red algae that lives in fresh water. It is a common nuisance in freshwater aquaria. It is the only species in the genus Compsopogon and the only representative of the family Compsopogonaceae. It is found in North America, South America, Europe, Africa, Asia, Australasia and Oceania. Compsopogon can tolerate a wide range of conditions in freshwater streams and occasionally in brackish lagoons and estuaries. It propagates by asexual spores.

Picocystis is a monotypic genus of green algae, the sole species is Picocystis salinarum. It is placed within its own class, Picocystophyceae in the division Chlorophyta.

Bangiomorpha pubescens is a species of red algae in the order Bangiales. It is the first known sexually reproducing organism. A multicellular fossil of Bangiomorpha pubescens was recovered from the Hunting Formation in Somerset Island, Canada that strongly resembles the modern red alga Bangia despite occurring in rocks dating to , during the Stenian period. This species is the oldest example of an organism belonging to an extant phylum. The fossil includes differentiated reproductive cells that are the oldest evidence of sexual reproduction. Sexual reproduction increased genetic variation, whi

Flabellia is a genus of green algae in the family Halimedaceae. Flabellaria is an accepted synonym of this genus. It is a monotypic genus and Flabellia petiolata is the only species; it is found in the eastern Atlantic Ocean and the Mediterranean Sea.

Platydorina is a genus of microscopic green algae in the family Volvocaceae. It contains only one species, Platydorina caudata. It was described by Charles Atwood Kofoid in 1899.

Furcellaria is a genus of red algae. It is a monotypic genus, the only species being Furcellaria lumbricalis, which has commercial importance as a raw material for carrageenan production. It is mainly harvested from the waters of Denmark and Canada.

Blastophysa is a genus of green algae in the class Ulvophyceae. , in AlgaeBase the only species is Blastophysa rhizopus.

Lanceola is a genus of green algae in the family Characiaceae, containing a single species, Lanceola spatulifera. It is found in freshwater habitats.

Tetrabaena is a monotypic genus of green algae containing the species Tetrabaena socialis. It primarily occurs in freshwater, although it has been found in saltwater on at least one occasion. Although rare, it has a cosmopolitan distribution and has even been found from Antarctica.

Arthrochaete is a genus of green algae, in the family Chaetophoraceae, containing the sole species Arthrochaete penetrans.

Prasinococcus is a monotypic genus of green algae, containing the only species Prasinococcus capsulatus, in the monotypic family Prasinococcaceae. This unicellular algal species was discovered in 1990 in the West Pacific Ocean and has characteristic reproduction methods as well as an interesting and potentially exploitable morphology. This is the only species in the genus, though various strains exist, for example URI 266G is the Atlantic clone.

Entwisleia is a monotypic genus in the red algae family, Entwisleiaceae. There is just one species (the type species) in this genus, Entwisleia bella, from south-eastern Tasmania and represents both a new family and a new order (Entwisleiales) in the Nemaliophycidae.

Klebahniella is a genus of green algae in the family Chaetophoraceae, containing the sole species Klebahniella elegans. It is a freshwater alga that occurs in or within the gelatinous colony of Nostoc verrucosum, a cyanobacterium.

Basichlamys is a monotypic genus of colonial green algae in the family Tetrabaenaceae. The sole species is Basichlamys sacculifera. It is rare, but cosmopolitan in freshwaters.
