Cutleriaceae is a family of brown algae. It includes two genera, Cutleria and Zanardinia . [1]
Brown algae are a large group of multicellular algae comprising the class Phaeophyceae. They include many seaweeds located in colder waters of the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, Macrocystis, a kelp of the order Laminariales, may reach 60 m (200 ft) in length and forms prominent underwater kelp forests that contain a high level of biodiversity. Another example is Sargassum, which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Some members of the class, such as kelps, are used by humans as food.
Sporochnacaeae is the only family in the order Sporochnales in the brown algae. Member of this family are thread-like algae growing by means of an intercalary row of dome shaped cells at the base of the hairs.
Dictyotales is a large order in the brown algae containing the single family Dictyotaceae. Members of this order generally prefer warmer waters than other brown algae, and are prevalent in tropical and subtropical waters thanks to their many chemical defenses to ward off grazers. They display an isomorphic haplodiploid life cycle and are characterized by vegetative growth through a single apical cell. One genus in this order, Padina, is the only calcareous member of the brown algae.
Ectocarpales is a very large order in the brown algae. The order includes families with pseudoparenchymatous (Splachnidiaceae) or true parenchymatous (Scytosiphonaceae) tissue. Pseudoparenchymatous refers to a filamentous alga with cells packed very close together to give an appearance of parenchymatous tissue, the latter being composed of cells which can truly divide in three dimensions, unusual among the algae. Filamentous algae are composed of cells that divide along a single plane, allowing only elongation to form filaments of one or more rows of cells. Algae that can divide in two planes can form sheet-like thalli or bodies. Cells that can divide in a third plane potentially allow for the organism to develop a more complex body plan, and diversification of body plans into an erect thallus of some sort and a holdfast for attaching the upright portion to the substrate.
Sargassaceae is a family of brown algae in the order Fucales.
Syringodermataceae is a family of brown algae. It includes two genera, Microzonia and Syringoderma.
Ishigeales is an order of brown algae. It includes two families, Ishigeaceae and Petrodermataceae. The genus Diplura is also included, but not placed to family.
Tilopteridales is an order of brown algae with isomorphic alternation of generations.
Scytothamnales is an order of brown algae.
Discosporangiales is an order of brown algae. It includes two families, Choristocarpaceae and Discosporangiaceae.
Ralfsiales is an order of crustose brown algae containing two families.
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.
Splachnidiaceae is a family of brown algae in the order Scytothamnales.
Scytothamnus is a brown algae genus in the family Splachnidiaceae.
Ralfsiaceae is a family of brown algae in the order Ralfsiales.
Phyllariaceae is a family of brown algae in the order Tilopteridales.
Scytosiphonaceae is a family of brown algae in the order Ectocarpales.
Ectocarpaceae is a family of brown algae in the order Ectocarpales. It includes four genera, Ectocarpus, Kuckuckia, Pleurocladia, and Spongostema.
Acinetosporaceae is a family of brown algae in the order Ectocarpales.
Fucophycidae is a subclass of Phaeophyceae which contains the most complex and evolved orders of Chromista algae. The members of this subclass have stalks with several morphological forms and distinct structures, characterized by an intercalary growth and a basic heteromorphic, sometimes secondarily iso- or sub-isomorphic life cycle.
