Scientific Description

Habit and structure. Thallus light pink, with a limited prostrate system and erect axes to 2 cm in height, loosely corticated in basal parts by filaments arising from basal cells of lateral branches. Primary axes with indeterminate lateral branches arising every second axial cell. Axial cells 5–7 µm in diameter near apices, broadening to 15–20 µm in diameter in mid plant (L/B 5), with lower cells to 50 µm in diameter. Gland cells borne abaxially on basal cells of laterals, spherical, 7–14 µm in diameter.

Reproduction. Tetrasporangia borne adaxially on basal cells of lateral branches, sometimes also on suprabasal cells and corticating cells, ellipsoidal, 30–40 x 20–25 µm, cruciate or decussate. Other reproductive structures not observed.

Distribution. Probably widespread in the Indo-West Pacific; in Australia known only from the present collections.

Habitat. Epiltihic in the subtidal.
