Jean Vincent Félix Lamouroux (1779–1825) was the first, in 1813, to separate the algae into groups on the basis of colour (Dixon and Irvine, 1977 p. 59).[18] At this time all coralline algae were considered animals, it was R. Philippi who in 1837 published his paper in which he finally recognized that coralline algae were not animals and he proposed the generic names Lithophyllum and Lithothamnion (Irvine and Chamberlain, 1994 p. 11).[19]
