The Delesseriaceae is a family of about 100 genera of marine red alga.
Rhodomelaceae is estimated to be the largest red algae family, with about 125 genera and over 700 species.
Bangia is an extant genus of division Rhodophyta that grows in marine or freshwater habitats. Bangia has small thalli with rapid growth and high reproductive output, and exhibits behavior characteristic of r-selected species. The plants are attached by down-growing rhizoids, usually in dense purple-black to rust-colored clumps. The chloroplasts of Bangia, like others in the division Rhodophyta, contain chlorophyll a and sometimes chlorophyll d, as well as accessory pigments such as phycobilin pigments and xanthophylls. Depending on the relative proportions of these pigments and the light conditions, the overall color of the plant can range from green to red to purple to grey; however, the red pigment, phycoerythrin, is usually dominant.
Galaxauraceae is a family of red algae (Rhodophyta) in the order Nemaliales.
Nemaliales is an order of red algae.
The Corallinophycidae is a grouping of several calcifying red algal lineages recovered by molecular analysis.
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.
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.
Colaconema is a genus of marine red algae. It is the only genus in the family ColaconemataceaeJ.T.Harper & G.W.Saunders which is the only family in Order ColaconematalesJ.T.Harper & G.W.Saunders.
Batrachospermaceae is a family of fresh water red algae (Rhodophyta). Genera within the Batrachospermaceae generally have a "Lemanea-type" life history with carpospores germinating to produce chantransia. Sporophyte phase with meiosis occurs in an apical cell to produce the gametophyte stage. Pit connections have two pit plug cap layers with the other layer enlarged. This family of freshwater red algae is uniaxial, meaning each filament with a single apical cell. The genera included within Batrachospermaceae are listed in the table below.
Entwisleia is a monotypic genus in the red algae family, Entwisleiaceae. There is just one species in this genus, Entwisleia bella, from south-eastern Tasmania and represents both a new family and a new order (Entwisleiales) in the Nemaliophycidae.
Callithamniaceae is a family of red algae (Rhodophyta) in the order Ceramiales. The family was first described by Friedrich Traugott Kützing in 1843.
Champia is a genus of red algae in the family Champiaceae, first described in 1809 by Nicaise Auguste Desvaux
Scinaiaceae is a family of red algae (Rhodophyta) in the order Nemaliales.
Liagoraceae is a family of red algae (Rhodophyta) in the order Nemaliales. The type genus is LiagoraJ.V.Lamouroux.
Halymeniales is an order of red algae belonging to the class Florideophyceae and the subclass Rhodymeniophycidae.
