Fucales genera

Fucus is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world.

Sargassum is a genus of brown macroalgae (seaweed) in the order Fucales of the class Phaeophyceae. This brown macroalgae comes from the Sargasso Sea, which was named because it hosts large amounts of Sargassum. Sargassum can extend for kilometers across the ocean surface, forming golden brown drifting mats that move with the currents and wind; in recent years, Sargassum has been known for arriving in large quantities throughout the Caribbean region. More recently, scientists have found using satellite data that a new hotspot has been forming from western Africa and extends into the Caribbean S

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 (from the White Sea to Portugal) 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 ha

Cystoseira is a genus of brown algae in the order Fucales.

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.

Durvillaea is a genus of large brown algae in the monotypic family Durvillaeaceae. All members of the genus are found in the southern hemisphere, including Australia, New Zealand, South America, and various subantarctic islands. Durvillaea, commonly known as southern bull kelps, occur on rocky, wave-exposed shorelines and provide a habitat for numerous intertidal organisms. Many species exhibit a honeycomb-like structure in their fronds that provides buoyancy, which allows individuals detached from substrates to raft alive at sea, permitting dispersal for hundreds of days over thousands of kil

Bifurcaria is a genus of brown algae seaweeds found on rocky North American and European shores and tidepools of the Atlantic Ocean. One species is also found on the shores of the Galapagos Islands in the Pacific Ocean.

Himanthalia is a genus of brown algae. It is the only genus in the family Himanthaliaceae in the order Fucales. It includes two species: Himanthalia durvillei and Himanthalia elongata.

Silvetia is a genus of brown algae, commonly known as rockweed, found in the intertidal zone of rocky seashores of the Pacific Ocean. These were originally classified as members of the genus Pelvetia. In 1999, Silvetia sp. was created as a separate species from Pelvetia canaliculata due to differences of oogonium structure and of nucleic acid sequences of the rDNA. It was renamed in honor of Paul Silva, Curator of Algae at the Herbarium of the University of California, Berkeley. There are three species and one subspecies.

Halidrys is a genus of brown algae belonging to the family Sargassaceae.
