Ulotrichales is an order of green algae in the class Ulvophyceae. [2]
Genera unplaced to family ( incertae sedis ):
Chlorophyta is a taxon of green algae informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it is a highly paraphyletic group of all the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms. In newer classifications, it is the sister clade of the streptophytes/charophytes. The clade Streptophyta consists of the Charophyta in which the Embryophyta emerged. In this latter sense the Chlorophyta includes only about 4,300 species. About 90% of all known species live in freshwater. Like the land plants, green algae contain chlorophyll a and chlorophyll b and store food as starch in their plastids.
Chlamydomonadales, also known as Volvocales, are an order of flagellated or pseudociliated green algae, specifically of the Chlorophyceae. Chlamydomonadales can form planar or spherical colonies. These vary from Gonium up to Volvox. Each cell has two flagella, and is similar in appearance to Chlamydomonas, with the flagella throughout the colony moving in coordination.
Mamiellales are an order of green algae in the class Mamiellophyceae. Their cells and flagella are covered with spiderweb-like scales of several types. Some species lack scales but possess pigments similar to those of the scale-bearing species.
Prasiolales is an order of green algae in the class Trebouxiophyceae.
Aphanochaetaceae is a family of algae in the order Chaetophorales.
Caulerpaceae is a family of green algae in the order Bryopsidales.
Chlorellaceae are a family of green algae in the order Chlorellales.
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.
Cladophoraceae are a family of green algae in the order the Cladophorales. This family includes notably the genus Chaetomorpha which has a few members used in saltwater aquariums.
The Dasycladaceae is one of the two extant families of green algae of the order Dasycladales. When found in Palaeozoic limestones, they typically indicate depositional depth of less than 5m.
Trentepohliaceae are a family of green algae in the order Trentepohliales.
Collinsiella is a genus of green algae in the order Ulotrichales.
Eugomontia is a genus of green algae in the order Ulotrichales.
Gloeotilopsis is a genus of green algae, in the order Ulotrichales.
Monomastix is a genus of green algae in the class Mamiellophyceae. It is the only genus in the family Monomastigaceae, which in turn is the only family in the order Monomastigales.
Pseudendocloniopsis is a genus of green algae in the order Ulotrichales.
The Gonatozygaceae are one of four families of Charophyte green algae in the order Desmidiales (desmids).
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.
