Description Thallus black-violet, brownish violet or dark green, fasciculate, joined into sparsely pseudobranched tufts, up to 5 mm long, rarely in solitary filaments. Filaments ± straight. Sheaths in lower part firm, seemingly wide, lamellated, in upper part narrow, firm, sometimes transversely folded, containing one or several trichomes, often motile with rotation around the long axis. Trichomes pale blue-green, greyish purple to brownish violet or yellowish, (7) 8-10 (11) μm wide, not constricted at the often granulated cross-walls, attenuated at the ends. Cells discoid, 2-4x shorter than wide, 2.4-5 μm long, often keritomized. Apical cells capitate, narrowed or short- or long-conical, straight or curved, with rounded, flat or acute-conical calyptra.

Harmful effect Marine mats from New Caledonia dominated by this species were found to produce homoanatoxin-a (Méjean et al. 2010). Authors suggest a possible implication in human poisoning events with giant clams (Méjean et al. 2010). [details]
