Sporolithon is a genus of red coralline algae in the family Sporolithaceae, in the order Corallinales. [1]
the World Register of Marine Species includes the following species in the genus:- [2]
Phycology is the scientific study of algae. Also known as algology, phycology is a branch of life science.
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.
Turbinaria is a genus of brown algae (Phaeophyceae) found primarily in tropical marine waters. It generally grows on rocky substrates. In tropical Turbinaria species that are often preferentially consumed by herbivorous fishes and echinoids, there is a relatively low level of phenolics and tannins.
The Corallinaceae are one of the two extant Coralline families of red algae; they are differentiated from the morphologically similar Sporolithaceae by their formation of grouped sporangial chambers, clustered into sori. The Corallinoideae is monophyletic; the other subfamilies form another monophyletic group.
Rhodomelaceae is estimated to be the largest red algae family, with about 125 genera and over 700 species.
Lithophyllum is a genus of thalloid red algae belonging to the family Corallinaceae.
Porolithon is a genus of red algae comprising 24 species. The Porolithon are the primary reef building algae. When coral reefs reach sea level, the corals break under the high energy impact of the waves, while the coralline red algae, primarily Porolithon, continuing building and cementing the reef structure.
Rhodymenia is a genus of red algae, containing the following species:
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.
Amphiroa is a genus of thalloid red algae comprising 55 species. Specimens can reach around 30 cm in size. The thalli take a crustose form; dichotomous branches are formed. The organisms possess secondary pit connections. Amphiroa reproduces by means of conceptacles; it produces tetraspores. Its pore canals are lined with parallel filaments; the morphology of the pore canal is a key trait used to delineate species within the genus.
Laurencia is a genus of red algae that grow in temperate and tropical shore areas, in littoral to sublittoral habitats, at depths up to 65 m (213 ft).
Stypopodium is a genus of thalloid brown alga in the family Dictyotaceae. Members of the genus are found in shallow tropical and subtropical seas around Africa, Pakistan, India, Japan, Indonesia, Australia, Micronesia, the Caribbean, Venezuela, and Brazil.
Spongites yendoi is a species of crustose red seaweed with a hard, calcareous skeleton in the family Corallinaceae. It is found on the lower shore as part of a diverse community in the southeastern Atlantic Ocean and the Indo-Pacific Ocean.
Phyllophoraceae is a family of red algae in the order Gigartinales.
Phyllophora is a genus of red algae in the family Phyllophoraceae.
Sporolithon ptychoides is a species of crustose red seaweed with a hard, calcareous skeleton in the family Corallinaceae. It has a widespread distribution, being present in the Pacific and Indian Oceans, the Mediterranean Sea and the southwestern Atlantic Ocean.
Crouania is a genus of red algae (Rhodophyta) in the Callithamniaceae family. The name of the genus honours the Crouan brothers, Pierre-Louis Crouan and Hippolyte-Marie Crouan. It was first described by Jacob Georg Agardh in 1842, and the type species is Crouania attenuata.
Champia is a genus of red algae in the family Champiaceae, first described in 1809 by Nicaise Auguste Desvaux
