Short description Morphology
Pericentral cells: 8 to 10. Dark brown thalli with an extensive creeping system. Trichoblasts formed in radial sequence in erect and prostrate axes, with erect filaments arising cicatrigenously and more or less unilaterally from adaxial scar cells. Oblong spermatangial branches sometimes subtended by trichoblasts, which arise one per segment (Ref. 87158).
Occurs in outer fore reef ridges at depths around 20 m; epiphytic on Dictyota dichotoma (Ref. 87158).
