Association with Phymatolithon lenormandii and Hildenbrandia rubra

Description (English)

The characteristic species of this association are the red algae Phymatolithon lenormandii and Hildenbrandia rubra. This association lives under the red alga Lithophyllum byssoides (ex Lithophyllum lichenoides) edge and at the entrance to mediolittoral caves, in sciaphilous ambiences. Some writers signal it at the level of small cavities in the substratum of Cystoseira amentacea. There it is probably an enclave in the superficial fringe of the infralittoral stage. Characteristic species are few: Phymatolithon lenormandii, Cruoriella armorica, Hildenbrandia rubra and Gymnothamnion elegans. In the most sciaphilous situations Phymatolithon lenormandii disappears.
