Codium prostratum Levring 1938: 16-17

Thallus dark green, creeping (repent) and rarely erect, subdichotomously branching, up to 16 cm across, branches terete or slightly compressed, overlapping, 3-9 mm thick. Utricles subcylindrical or slightly club-shaped, often tapering towards the base, 720-1310 µm long; apices truncate to slightly rounded. Hairs or hair-scars abundant, 1-9 per utricle, borne just below apex. Gametangia usually subcylindrical, or lanceolate-ovoid, 235-365 µm long, 1-3 per utricle, on pedicles, above middle of utricles.

Collections, ecology and regional distribution

Dwesa, Transkei, through KZN (44-58), in lower eulittoral zone and rock pools.

World distribution: Western Indian Ocean (Mozambique, Kenya, Mauritius, Réunion) also Fiji (Silva et al. 1996, Guiry & Guiry 2014).
