Lithophyllum
''Lithophyllum'' is a genus of thalloid red algae belonging to the family Corallinaceae. Fossil record This genus is known in the fossil record from the Silurian to the Quaternary (from about 418.7 to 0.0 million years ago). Fossils of species within this genus have been found in Europe, United States, South America, Egypt, Iran, Iraq, India, Japan and Australia. Description The monomerous, crustose thalli are composed of a single system of filaments which grow close to the underlying surface. ''Lithophyllum'' reproduces by means of conceptacles. The epithallus is periodically shed to avoid organisms growing on top of the alga. Species The valid species currently considered to belong to this genus are: *''Lithophyllum acanthinum'' Foslie, 1907 *''Lithophyllum accedens'' Foslie, 1907 *''Lithophyllum acrocamptum'' Heydrich, 1902 *''Lithophyllum aequum'' Foslie, 1907 *''Lithophyllum albanense'' Lemoine, 1924 *'' Lithophyllum almanense'' Lemoine, 1920 *''Lithop ...

''Lithophyllum'' is a genus of thalloid red algae belonging to the family Corallinaceae. Fossil record This genus is known in the fossil record from the Silurian to the Quaternary (from about 418.7 to 0.0 million years ago). Fossils of species within this genus have been found in Europe, United States, South America, Egypt, Iran, Iraq, India, Japan and Australia. Description The monomerous, crustose thalli are composed of a single system of filaments which grow close to the underlying surface. ''Lithophyllum'' reproduces by means of conceptacles. The epithallus The epithallium or epithallus is the outer layer of a crustose coralline alga, which in some species is periodically shed to prevent organisms from attaching to and overgrowing the alga. Structure It is defined as the cells above the wikt:intercala ... is periodically shed to avoid organisms growing on top of the alga.
