Corallinaceae

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.

Corallina is a genus of red seaweeds with hard, abrasive calcareous skeletons in the family Corallinaceae. They are stiff, branched frond-like protists with articulated stipes. Corallina, like all red algae, are not considered plants under some definitions, but can be considered as belonging to plants in a broad sense.

Porolithon is a genus of coralline red algae. Porolithon are the primary reef building algae. When coral reefs reach sea level, many corals break under the high energy impact of the waves, while coralline red algae, primarily Porolithon, continuing building and cementing the reef structure.

Lithothamnion is a genus of thalloid red alga comprising 103 species. Its members are known by a number of common names. The monomerous, crustose thalli are composed of a single system of filaments which grow close to the underlying surface. Lithothamnion reproduces by means of multiporate conceptacles.

Bossiella is a genus of coralline algae with 5 recognised species. It reproduces via conceptacles; individual thalli only produce conceptacles of a single sex.

Pneophyllum is a genus of multicellular red algae in the family Corallinaceae and subfamily Chamberlainoideae.

genus of algae

Amphiroa is a genus of thalloid red algae under the family Corallinaceae.

Calliarthron is a genus containing two species of thalloid intertidal alga. Specimens can reach around 30 cm in size. The thalli take a crustose form. The organisms lack secondary pit connections. Calliarthron reproduces by means of conceptacles; it produces tetraspores, dispores and carpospores. The genus has lignin and contains secondary cell walls, traits which are normally associated with the vascular plants. It is similar to the genus Bossiella.

Metagoniolithon is a genus of red algae belonging to the family Corallinaceae.

genus of algae

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.

species of alga

The Corallinoideae are a subfamily of coralline algae. The majority of genera are geniculate, but some have secondarily re-evolved into non-geniculate (crustose) forms.
