Characiellopsis is a genus of green algae in the family Characiaceae. Two species are known: Characiellopsis anophelesii and Characiellopsis skujae. [1]
Characiellopsis consists of solitary cells that are elongate and attached to a substrate via a pad of mucilage. Cells contain a single central nucleus. Young cells contain a single chloroplast, while older cells contain multiple; each chloroplast has a single pyrenoid. Cells reproduce by 2-flagellated zoospores. These zoospore escape from the tip of the mother cell via a tear in the mother cell's wall. [2]
Characiellopsis anophelesii consists of solitary cells that are attached to mosquito ( Anopheles ) larvae. [2]
Characiellopsis skujae consists of solitary cells that are elongated to ovoid, attached to a surface via a thick stalk. The cell walls are very thick, and the tip of the cell has a refractive ring-shaped structure visible in light microscopy. Cells contain a single chloroplast filling the cell, each with a single pyrenoid. The apical ring structure is very distinctive, and it shares this characteristic with another taxon, Characium obtusum; the two species are probably synonymous. [3]
Bracteacoccus is a genus of green algae, the sole genus of the family Bracteacoccaceae. It is a terrestrial alga commonly found in soils, from the tropics to the poles.
Characium is a genus of green algae in the family Characiaceae. It is very commonly found in freshwater habitats, where it is attached to phytoplankton or zooplankton.
Dictyochloris is a genus of green algae in the class Chlorophyceae. It is the sole genus of the family Dictyochloridaceae. It is commonly found in terrestrial and subaerial habitats.
Golenkinia is a genus of green algae first described in 1894 by Robert Chodat. The genus is named for the Russian phycologist Mikhail Iljitsch Golenkin. Golenkinia species live in fresh water and are found around the world.
Lagerheimia is a genus of green algae in the family Oocystaceae. It is commonly found in freshwater habitats all over the world, although some species are rare and have only been recorded from Europe or the United States.
Micractinium is a genus of green algae in the family Chlorellaceae. Species of the genus Micractinium are common in freshwater habitats. A few species are found as endosymbionts of protozoa, such as Micractinium conductrix and Micractinium tetrahymenae.
Neochloris is a genus of green algae in the family Neochloridaceae. It is found in freshwater aquatic and terrestrial soil habitats.
Pseudomuriella is a genus of green algae, specifically of the class Chlorophyceae. It is the sole genus of the family Pseudomuriellaceae. It is a terrestrial alga that inhabits soils.
Pseudoschroederia is a genus of green algae in the family Characiaceae. It is planktonic in freshwater habitats, and probably has a cosmopolitan distribution. The genus Pseudoschroederia was circumscribed by Eberhard Hegewald and Eberhard Schnepf in 1986. The genus was distinguished from the similar Schroederia by being heteropolar and differing cell structure. However, some authors do not consider the genera to be separate.
Raphidocelis is a genus of green algae in the family Selenastraceae. They are found in freshwater habitats.
Schroederia is a genus of green algae in the family Schroederiaceae. Schroederiaceae is a monotypic taxon; Schroederia is its only genus.
Sorastrum is a genus of green algae in the family Hydrodictyaceae. It is a component of the phytoplankton of freshwater ponds, lakes, and ditches. Sorastrum is common in tropical to temperate regions of the world, but due to its small size it is often overlooked.
Tetraedron is a genus of green algae in the family Hydrodictyaceae. It may also be spelled as Tetraëdron.
Gilbertsmithia is a genus of green algae in the family Scenedesmaceae, containing the single species Gilbertsmithia grandis. It was named after the American botanist Gilbert Morgan Smith. This remarkable alga has only been recorded once from a muddy rainwater pool in Madras, India.
Deuterocharacium is a genus of green algae in the family Characiaceae. It is found in freshwater habitats, attached to algae or detritus. It is rare and has only been recorded from Europe.
Chlorotetraedron is a genus of green algae, in the family Neochloridaceae. The name may also be written as Chlorotetraëdon. It is found as freshwater plankton or in soil.
Korshikoviella is a genus of green algae in the family Characiaceae.
Poloidion is a genus of green algae in the family Neochloridaceae, containing the single species Poloidion didymos. It is an extremely rare genus, which has only been recorded once on moist soil and rocks in Austria.
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.
Bracteamorpha is a genus of green algae in the order Sphaeropleales, and is the only genus in the family Bracteamorphaceae. It contains a single species, Bracteamorpha trainorii.
