[2] Rissoella verruculosa has an amino acid composition with relatively high levels of lysine and methionine for a plant.
It is an autotrophic plant that creates its organic matter by photosynthesis from water, carbon dioxide and mineral salts with green chlorophyll and with other pigments such as red phycoyerythrin that capture light.
Gametophyte carries the sexual organs that produce globular cystocarpes and contain a second generation that comes from the development of the fertilized egg.
Rissoella verruculosa is visible at the end of the winter season until summer when it extends over the meliottoral rock.
It is found especially on silica substrates and very rare on limestone coasts that are calcifuge exposed to sun and water, which will allow it to withstand temperature, salinity
