Cystoseira foeniculacea is a species of brown alga in the genus Cystoseira .
Cystoseira foeniculacea forms tufts up to 30 centimetres (12 in) long, attached to the substrate with a broad disc-shaped holdfast. [2] It has many cryptostomata, and conceptacles that may be male, female or both. [3] Up to 12 oogonia may develop in each conceptacle. The proximity of the oogonia and the antheridia strongly suggest that C. foeniculacea self-fertilises. [3]
Cystoseira foeniculacea is found in the mid-littoral zone and in other sheltered places, from the British Isles to Senegal, and in the Mediterranean Sea. [2]
Cystoseira foeniculacea was first described by Carl Linnaeus in his seminal 1753 work Species Plantarum , under the name "Fucus foeniculaceus". Three other species described by Linnaeus were also later determined to refer to the same species by Dawson Turner, who chose the epithet "foeniculacea" as the valid name (under the "principle of the first reviser"). [4] The vernacular name "bushy feather wrack" has been proposed for this species. [5]
Fucus vesiculosus, known by the common names bladderwrack, black tang, rockweed, sea grapes, bladder fucus, sea oak, cut weed, dyers fucus, red fucus and rock wrack, is a seaweed found on the coasts of the North Sea, the western Baltic Sea and the Atlantic and Pacific Oceans. It was the original source of iodine, discovered in 1811, and was used extensively to treat goitre, a swelling of the thyroid gland related to iodine deficiency.
Fucus is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world.
Ascophyllum nodosum is a large, common cold water seaweed or brown alga (Phaeophyceae) in the family Fucaceae. Its common names include knotted wrack, egg wrack, feamainn bhuí, rockweed, knotted kelp and Norwegian kelp. It grows only in the northern Atlantic Ocean, along the north-western coast of Europe including east Greenland and the north-eastern coast of North America. Its range further south of these latitudes is limited by warmer ocean waters. It dominates the intertidal zone. Ascophyllum nodosum has been used numerous times in scientific research and has even been found to benefit humans through consumption.
Fucus serratus is a seaweed of the north Atlantic Ocean, known as toothed wrack, serrated wrack, or saw rack.
Fucus spiralis is a species of seaweed, a brown alga, living on the littoral shore of the Atlantic coasts of Europe and North America. It has the common names of spiral wrack and flat wrack.
Pelvetia canaliculata, the channelled wrack, is a very common brown alga (Phaeophyceae) found on the rocks of the upper shores of Europe. It is the only species remaining in the monotypic genus Pelvetia. In 1999, the other members of this genus were reclassified as Silvetia due to differences of oogonium structure and of nucleic acid sequences of the rDNA.

Cystoseira is a genus of brown algae in the order Fucales.
The history of phycology is the history of the scientific study of algae. Human interest in plants as food goes back into the origins of the species, and knowledge of algae can be traced back more than two thousand years. However, only in the last three hundred years has that knowledge evolved into a rapidly developing science.
Conceptacles are specialized cavities of marine and freshwater algae that contain the reproductive organs. They are situated in the receptacle and open by a small ostiole. Conceptacles are present in Corallinaceae, and Hildenbrandiales, as well as the brown Fucales. In the Fucales there is no haploid phase in the reproductive cycle and therefore no alternation of generations. The thallus is a sporophyte. The diploid plants produce male (antheridia) and female (oogonia) gametangia by meiosis. The gametes are released into the surrounding water; after fusion, the zygote settles and begins growth.
Synarthrophyton is a genus of thalloid red algae comprising eight species. The monomerous, crustose thalli are composed of a single system of filaments which grow close to the underlying surface. Synarthrophyton reproduces by means of flask-shaped multiporate conceptacles; it produces tetraspores and dispores. Mucus plugs the opening of young conceptacles, which open as they mature.
Trentepohlia aurea is a species of filamentous terrestrial green alga with a worldwide distribution. It grows on rocks, old walls and the trunks and branches of trees such as oaks, elms, and the Monterey cypress. The orange coloration results from carotenoid pigments in the algal cells. It is probably the most widespread and abundant species of Trentepohlia in the Britain and Ireland.
Gongolaria baccata is a species of brown seaweed in the family Fucaceae. It is found in the north east Atlantic, the Baltic Sea and the Mediterranean Sea. The species name baccata means "berry-like" and refers to the small air bladders.
Chorda filum, commonly known as dead man's rope or sea lace among other names, is a species of brown algae in the genus Chorda. It is widespread in the temperate waters of the northern hemisphere. The species has numerous other common names related to its physical appearance. These include mermaid's tresses, cat's gut or sea-catgut, bootlace weed, sea-twine, and mermaid's fishing line.
Palmariaceae is a family of algae. It includes the edible seaweed dulse.
Lithophyllum incrustans, also known by its common names coraline crust and paint weed, is a small pinkish species of seaweed.
Gongolaria is a genus of brown algae in the family Sargassaceae. It was formerly included in Cystoseira, but was recently found not to be closely related to it.
Ericaria is a genus of brown algae in the family Sargassaceae. It was formerly included in Cystoseira, but was recently found not to be closely related to it.
Ericaria selaginoides is a large marine brown algae.
Cystoseira pustulata is a species of brown alga in the genus Cystoseira.
