Codium apiculatum (Codiaceae, Chlorophyta), a new species from southern and southwestern Australia.

A new species of Codium, C. apiculatum P.C. Silva, M.E. Chacana et H.B.S. Womersley, is described on the basis of several subtidal collections from southern and southwestern Australia. It is characterized by its utricles, which are stout, subcylindical to slightly clavate, bearing several hairs (or hair scars) very close to the apex, and by the branch tips, which are apiculate.
