General Description

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).

Biology
