Codium is a genus of seaweed in the Chlorophyta of the order Bryopsidales. There are about 50 species worldwide.[1]

Description

The genus has thalli of two forms, either erect or prostrate. The erect plants are dichotomously branched to 40 centimetres (16 in) long with branches forming a compact spongy structure, not calcareous. The final branches form a surface layer of close palisade cortex of 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.[2]

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. In 1837 it was found in Church Bay in County Antrim,[3] but has not been found there since.

There are other species of "doubtful validity":- Codium amphibium is included in William Henry Harvey's Phycologia Britannica Pl.xxxv. 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).
