Thalli 14-30 cm high, consisting of few to many coarse, cartilaginous, dark purplish red shoots from a crustose stoloniferous base; erect shoots usually greater than 2 mm in diameter, terete throughout, usually forked once or twice 4-9 cm above the base into several main branches that are irregularly dichotomously to oppositely branched 2-4 more times; lower axes naked; upper branches provided on all sides at more or less regular intervals with simple or branched fructiferous ramuli of variable thickness; cortex 7-8 cell layers thick; medullary cells variable in size and shape, 1.5- 17 µm in width. Cystocarps 400-700 µm in diameter, mostly forming dense pedicellate clusters at intervals on lateral branches; carpospores 12-18 µm in diameter. Spermatangial plants sparsely branched, lacking papillae, gracilariod in appearance. Tetrasporangial sori 150-300 µm in diameter, widely scattered in ramuli that point upward; tetrasporangia 32-41 µm diameter, formed in chains 5-7cells long.
