Thallus: Tufted, calcified, light pink to grey–red (often bleached), generally 5–10 cm in height, arising from a crustose or stoloniferous holdfast, with densely branched, erect, pinnate, geniculate fronds, these often with thinner adventitious branchlets not in the primary plane of branching.
Structure: Axial intergenicula compressed to subterete or cuneate, 300–900 µm broad and 300–700 µm long. Branchlet intergenicula terete, to 600 µm long and 250 µm in diameter, less than 100 µm in diameter near apices. Structure of intergenicula with 3–6 tiers of medullary cells, with lateral cell-fusions but without lateral pit-connections. Genicula with single tiers of elongate cells. Cortex on intergenicula with assurgent to anticlinal filaments, the outer cells bearing short epithallial cells.
Reproduction: Reproductive conceptacles axial and terminal, with branchlets usually present on carposporangial and tetrasporangial conceptacles. Tetrasporangia zonately divided.
