Scientific Description

Habit and structure. Thallus medium to dark green, (1–)2–4(–6) cm high and (0.5–)1–2(–7) cm across, with a short stipe to 1 cm long broadening gradually or very rapidly into an ovate, reniform or irregularly elongate lamina, occasionally slightly lobed or lacerate, usually faintly zonate, thin (0.5–1 mm and several filaments thick), felt-like and spongy. Filaments slender, (12–)18–25 µm in diameter, thin walled, repeatedly subdichotomous and laxly interwoven, constricted adjacent to a subdichotomy, with branch ends forming the surface layer; chloroplasts ovoid, amyloplasts present.

Reproduction. From ovoid to pyriform, stalked zooidangia formed laterally on the medullary filaments.

Distribution. From Hopetoun, W. Aust., to Inverloch, Vic.

Habitat. From low tide level (shaded) to 31 m deep on rough-water coasts.
