Chordariaceae
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.Pound, F. E. 1962 ''The Biology of the Algae'' Edward Arnold Ltd.

Brown Algae
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. 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 in length and forms prominent underwater kelp forests. Kelp forests like these 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. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and ...

Jakob Georg Agardh
Jacob Georg Agardh (8 December 1813 in Lund, Sweden – 17 January 1901 in Lund, Sweden) was a Swedish botanist, phycologist, and taxonomist. He was the son of Carl Adolph Agardh, and from 1854 until 1879 was professor of botany at Lund University. Agardh designed the current 1862 blueprints for the botanical garden Botaniska trädgården in Lund. In 1849, he was elected a member of the Royal Swedish Academy of Sciences. Agardh was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1878. It is said that the naturalist Mary Philadelphia Merrifield Mary Philadelphia Merrifield (née Watkins; 15 April 1804 – 4 January 1889) was a British writer on art and fashion.

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
