Habit and structure. Thallus erect, to 12 cm tall, very soft, dichotomously branched; branching congested distally with short internodes 3–5 mm long. Branches delicate, filiform, 1.5–2.0 mm diam., only slightly thicker basally. Utricles produced by enlargement of interutricular filaments, clavate, at times with a long tapered base, 280–440 μm long, 100–210 μm diam., markedly constricted below the rounded or truncate apex. Utricular wall thin, unornamented at the apex. Hairs (or hair scars) infrequent in a zone 40–90 μm below the apex. Medullary filaments 20–30 μm diam. Gametangia lanceolate or fusiform, 140–200 μm long, 60–120 μm diam., borne on short pedicels 200–300 μm below the apex of the utricle.

Distribution. Known only from the Philippines and northern W.A., where it appears to be rare.
