Electronic Flora of South Australia Family Fact Sheet
Phylum Chlorophyta
Thallus applanate, globose or erect and usually branched, composed of densely entwined filaments forming a medulla and a cortex of elongate utricles bearing lateral gametangia; cross walls absent, but in many species one medullary filament adjacent to the base of each utricle with a plug largely blocking the filament; cell walls of mannan; homoplastic, with chloroplasts only, containing siphonein and siphonoxanthin.
Life history diplontic with gametic meiosis, anisogamous.
Taxonomic notes: This order (Feldmann 1954) contains only the single genus Codium in the family Codiaceae. Some authors (e.g. Bold & Wynne 1978, p. 191) include it as a family of the Caulerpales.
