[4] Stackhouse, unfortunately, failed to provide holotype specimens for C. tomentosum (type species) and some of its dichotomously branching congeners leading to misidentifications; P.C.

Silva delineated C. tomentosum, C. fragile, and C. vermilara and established neotypes for each species to finally resolve this taxonomic blunder.

and noted as: "spreading in patches of great extent along the edge of the sea, over the surface of a turf-bog which meets the shore at Roundstone Bay" (Ireland).

tomentosoides, commonly known as "oyster thief", the increasing marine traffic has made it possible for it to escape its natural locality (Japan) and spread to Europe and USA forcing devastating biodiversity and aquacultural losses.

[16] A recent review on the bioactivity of the genus Codium has revealed that most of its polysaccharides, glycoproteins, galactans, anionic macromolecules, and other extracts/compounds have shown to have a variety of uses as immunostimulatory, anticoagulant, anticancer, anti-inflammatory, antibacterial, antifungal, and antiviral agent.

[17] Codium is used either fresh or dry and is typically cooked and seasoned with soy sauce and vinegar or mixed with kimchi.
