Description
Color: Yellow brown

Thalli about 25-40 cm in height, attaching by scutate discoid holdfasts. Main axes terete, about 2-3 mm in height, 2 mm diameter, giving rise to 2-3 flattened, smooth primary branches, about 3-4 mm broad. Secondary branches flattened, arising from the margins of the primary ones. Basal leaves lanceolate, about 4-5 cm long, 5-7 mm broad, margins with conspicuously shallow teeth, midrib vanishing below the apices. Upper leaves smaller, 2-3 cm long, 4-5 mm broad, bases asymmetrical, with very short stipe.

Vesicles ovate or ellipsoidal, often crowned with mucronates at the apices, borne on subcylindrical pedicles, often with flattened, upper portions. Cryptostomata slightly to moderately prominent, scattered on both sides of the midribs. Receptacles flattened, forked with coarsely dentate margins, arranged in glomerules, cymose, growing in axils of the leaflets.
