Amphiroa Peruana
''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. Species The valid species currently considered to belong to this genus are: # ''Amphiroa anastomosans'' Weber Bosse # ''Amphiroa anceps'' (Lamarck) Decaisne # ''Amphiroa annobonensis'' Pilger # ''Amphiroa annulata'' Me.Lemoine # ''Amphiroa articulata'' (Bory) Athanasiadis # ''Amphiroa beauvoisii'' J.V.Lamouroux # ''Amphiroa bowerbankii'' Harvey # ''Amphiroa brasiliana'' Decaisne # ''Amphiroa breviarticulata'' Areschoug # ''Amphiroa canaliculata'' G.Martens # ''Amphiroa capensis'' Areschoug # ''Amphiroa compressa'' M.Lemoine # ''Amphiro ...

Amphiroa Beauvoisii
''Amphiroa beauvoisii'' is a species of thalloid red algae in the Coralline algae, Corallinaceae family. It is widely distributed across the world, and can be found attached to rocks in intertidal areas. Individual organisms consist of a base of calcified material, tissue in the shape of branching fan-like planes growing out of it. It exhibits a wide range of morphologies based on where it is found, as well as different reproductive behaviors based on season and location. Description Plants of ''Amphiroa beauvoisii'' grow on the surface of rocks, attached on their undersides by a Calcification, calcified and crustose base. From this base, erect axes grow up to long. The axes are made up of alternating segments of calcified sections called intergenicula and non-calcified sections called Geniculate (alga), genicula.Harvey ''et al.'' 2009, 267. They branch out in a fan-like plane which is about tall,Economou-Amilli ''et al'', 262. usually split into two distinct branches, but ra ...
