Rhodomelaceae is estimated to be the largest red algae family, with about 125 genera and over 700 species. [1]
Rhodomelaceae includes the following tribes and genera: [2]
Gracilaria is a genus of red algae (Rhodophyta) notable for its economic importance as an agarophyte, as well as its use as a food for humans and various species of shellfish. Various species in the genus are cultivated among Asia, South America, Africa and Oceania.
Chordariaceae is a family of brown algae. Members of this family are may be filamentous, crustose with fused cells at the base, or they may be terete and differentiated into a central medulla and an outer photosynthetic cortex. They have a sporphytic thallus usually aggregated to form a pseudo-parenchyma.
The Delesseriaceae is a family of about 100 genera of marine red alga.
Halymenia a genus of a macroscopic red algae that grows in oceans worldwide.
Rhodymenia is a genus of red algae, containing the following species:
Plocamium is a genus of red algae in the family Plocamiaceae. It contains around 40 species and has a cosmopolitan distribution in temperate seas, although it is most diverse in the southern hemisphere. It is widely distributed in tropical and also warm-temperate and cold-temperate seas, such as northern Europe, the northern Arabian Sea and western Australia. They are also found in the Antarctic regions of Admiralty Bay and Terra Nova Bay.
Laurencia is a genus of red algae that grow in temperate and tropical shore areas, in littoral to sublittoral habitats, at depths up to 65 m (213 ft).
Solieriaceae is a family of red algae in the order Gigartinales.
Dumontiaceae is a red alga family in the order Gigartinales.
Chondria is a red alga genus in the family Rhodomelaceae.
Wrangeliaceae is a red alga family in the order Ceramiales. It was published by J.Agardh in 1851 in his book Species, genera et ordines algarum : seu descriptiones succinctae specierum.
Hypnea is a genus of red algae, and a well known carrageenophyte.
Phyllophora is a genus of red algae in the family Phyllophoraceae.
Acrosorium is a genus of marine red algae.
Dictyota is a genus of brown seaweed in the family Dictyotaceae. Species are predominantly found in tropical and subtropical seas, and are known to contain numerous chemicals (diterpenes) which have potential medicinal value. As at the end of 2017, some 237 different diterpenes had been identified from across the genus.
Callithamniaceae is a family of red algae (Rhodophyta) in the order Ceramiales. The family was first described by Friedrich Traugott Kützing in 1843.
