Distinctively branched branchlets. Long flattened relatively straight central stalk (stipe) with strongly zig-zagged flattened branches arising facing slightly backward down the stem in an alternating pattern on one plane (can sometimes form long branches with their own sub-branches). Branchlets (ramuli) are clustered, usually found towards the tips of the branches and are multi-branched in an alternate pattern. Holdfast at base is a simple and disc-conical shaped. Medium to dark brown. Up to 2 m long (thallus).
This species is one of the largest Cystophora algae and has been described as one of the most developed species in the genus. New chemical compounds have been discovered from studies analysing its chemistry.
Subtidal rocky reefs and tidal pools (when in rough wave conditions), in areas with moderate-strong wave action, to depth of 28 m.
