This is a marine species.

Description
Thallus upright, to 5-8 (-14) cm high, attached to rocks by a feltlike rhizoidal holdfast, bright green in colour (drying darker); axes compressed or subterete and becoming compressed in the lower portions, 0.9-2.5 mm wide and 0.5- 1.0 mm thick, dichotomously branched up to seven times, tapering slightly or not at all toward the apices, often with undulate margins; irregular shallow constrictions of the axes uncommon to prominent; apices truncate with a depressed apical pit. Structure of longitudinally arranged interwoven medullary siphons, 30-50 µm wide, giving rise to a single layer of peripheral utricles; utricles polygonal in surface view, distinctively clavate in transverse section, (50-) 64-76 (-94) mm in diameter and (153-) 161-186 (-200) mm high, with a flat apex, closely laterally adhering along the entire length of their faces; utricle stipe not eccentric, often with a distinctive swelling. Chloroplasts and amyloplasts present in the utricles and siphons. Reproductive structures immersed in the thallus, produced laterally from medullary siphons close to the base of the utricle stipe, ovoid to irregularly shaped, 80-130 µm in diameter.

Habitat
Lower part of the intertidal area, often in tidal pools, as well as in the shallow subtidal area (South Africa, southern Mozambique and the warm temperate part of Madagascar. Confined to the subtidal area (8-15 m depth) in Oman and Western Australia.
