Florideophyceae

species of edible alga

Florideophyceae is a class of exclusively multicellular red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. Most, but not all, genera have three phases to the life cycle. In the subclass Nemaliophycidae there are three orders, Balbianiales, Batrachospermales, and Thoreales, which lives exclusively in freshwater. When alive, the Florideophyceae appear bright red or even violet. Howe

Palmariales is an order of marine algae. It includes the edible seaweed dulse (Palmaria palmata).

Ahnfeltia is a genus of red algae.

genus of algae

The Sporolithaceae is the only known family of algae in the Sporolithales order.

Hildenbrandiales is an order of crustose forms red alga which bear conceptacles and produce secondary pit-connections. They reproduce by vegetative gemmae as well as tetrasporangia, which are produced inside the conceptacles. The way in which the tetraspores are produced is unusual enough to justify the formation of this distinct order. Some members of the order are known from freshwater rivers as well.

Atractophora is a monotypic genus of red algae of the family Atractophoraceae (within the Order Atractophorales). It only contains one known species Atractophora hypnoides .

REDIRECT Thoreaceae

Thorea is a genus of fresh water algae in the division Rhodophyta (red algae). Thorea is a small alga with filaments up to 200 cm long, dark green in colour and not red as are marine Rhodophyta. The filaments have only as few secondary branches.

Titanophora is a genus of seaweeds belonging to family Schizymeniaceae of the order Nemastomatales.

Entwisleia is a monotypic genus in the red algae family, Entwisleiaceae. There is just one species (the type species) in this genus, Entwisleia bella, from south-eastern Tasmania and represents both a new family and a new order (Entwisleiales) in the Nemaliophycidae.

Halymenia a genus of a macroscopic red algae that grows in oceans worldwide.

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 (maritime Antarctica, Antarctic Peninsula) and Terra Nova Bay (in the Ross Sea).

Sporolithon is a genus of red coralline algae in the family Sporolithaceae, in the order Corallinales.

The Corallinophycidae is a grouping of several calcifying red algal lineages recovered by molecular analysis.

Chylocladia is a genus of red algae belonging to the family Champiaceae.

Halosaccion is a genus of red algae belonging to the family Palmariaceae.

The Rhodogorgonales are an order of red algae, a sister group to the corallines. They are always thalloid and calcified; their calcification is very different from the corallines, as individual calcite crystals are deposited in the cell wall of specialised cells; this suggests that the evolution of calcification may have been independent from the corallines. They have no fossil record.
