Chondria is a red alga genus in the family Rhodomelaceae.
The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha, the former members of which are known under the common name green nori.
Cystophora is a genus of brown algae found mostly in temperate waters around Australia. Most of the southern Australian species can be immediately recognised as belonging to this genus by their characteristic zigzag branching pattern. Identification of individual species is generally more difficult and relies on the size and shape of branches, particularly terminal branches, which are specialised reproductive structures known as receptacles. Due to their local diversity and dominance in southern Australia, they are regarded by some as 'the eucalypts of the underwater world'.
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.
Rhodomelaceae is estimated to be the largest red algae family, with about 125 genera and over 700 species.
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).
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.
Acrosorium is a genus of marine red algae.
Champia is a genus of red algae in the family Champiaceae, first described in 1809 by Nicaise Auguste Desvaux
Callithamnion is a genus of algae belonging to the family Callithamniaceae.
