Tufted, multiple cylindrical axes, arising from flat lying (prostrate) tangled branches. Upper branches (axes) are covered in fixed length (determinate), branched laterals arranged in a radial pattern. Very dark red-brown. Up to 10 cm long (thallus).
This alga often forms dense turfs. It grows on hard surfaces such as rocks and mussels, also occasionally as an epiphyte on other algae. It attaches to the surfaces with root-like (rhizoid) extensions on lower branches.
Low tide level, moderate to exposed waters, to depth of 6 m.
