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

Description (English)

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)
