There are about 50 species worldwide. Description The genus has Thallus, thalli of two forms, either erect or prostrate. The erect plants are Glossary of botanical terms#Dichotomous, dichotomously branched to long with branches forming a compact spongy structure, not calcareous. The final branches form a surface layer of close Palisade cell, palisade cortex of Utricle (seaweed), utricles. The non-erect species form either a prostrate or globular thallus with a velvet-like surface, the final branches forming a close cortex of utricles. Distribution Ireland Two of these species are very rare in Ireland. ''Codium adhaerens'' has been recorded from a few sites on the west coast and from Tory Island on the north coast in County Donegal.

''Codium spongiosum'' is a species of seaweed in the family Codiaceae. The light-green thallus has an applanate to pulvinate habit and is usually around across and thick. It has irregular lobes and moderately firm while alive becoming more spongy once dead. The utricles form in large clusters and are long and coated in many hairs. The species is similar to '' Codium lucasii'' which adheres more tightly to rock surfaces. It is epilithic in the subtidal to intertidal zones. Mostly situated in calmer waters from the low tide mark to several metres depth. It is often found in warmer waters but has a scattered distribution in colder waters. The species was first formally described by the botanist Harvey in 1855 in ''Some account of the marine botany of the colony of Western Australia,'' published in the ''Transactions of the Royal Irish Academy''. The type specimen was collected from King George Sound along the south coast of Western Australia. In Western Australia is found al ...
