Habit and structure. Thallus medium green, erect, repeatedly dichotomous, to 30 cm high, branches terete, 3–5 mm in diameter below, tapering to 1–2 mm in diameter at apices. Utricles short and irregularly swollen, 170–600 µm in diameter, 340–850 µm long, apices broadly rounded with wall scarcely to slightly thickened to 24(–50) µm; hairs (or scars) frequent. Medullary filaments 30–60 µm in diameter, with the plug usually closely adjacent to utricle, in some plants more distant on older utricles.
Reproduction. Gametangia elongate-ovoid, often tapering above, 70–140 µm in diameter and 150–240 µm long, 1–4 per utricle, borne on a short protuberance on lower half of utricle.
Distribution. From Shark Bay, W. Aust., around southern Australia and Tas., to Lake Macquarie, N.S.W. New Zealand.
Habitat. C harveyi occurs in the sublittoral, from low tide level to 30 m deep, on coasts of moderate water movement.
