Association with maerl (= Association with Lithothamnion corallioides and Phymatolithon calcareum) on Mediterranean coarse sands and gravel

Classification des habitats EUNIS 2022

Descriptif de l'habitat

An association characterised by the presence of two small many-branched calcareous algae species, Lithothamnion corallioides and Phymatolithon calcareum, unattached on sediments made up of coarse sands and gravels with a high proportion of detritic elements. Given their many-branched shape, these Lithothamnia never constitute bioconstructions or rhodolithes. Small Rhodophyceae may be present as epiphytes on the Lithothamnia. A similar community can also be found as an association facies of the biocenosis of the coastal detritic bottom (MC3.523)
