Association with maerl (Lithothamnion corallioides and Phymatholithon calcareum) on coastal dendritic bottoms
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 also occurs on coarse sediments (MB3.522).
