Note: The species is common in the intertidal and upper part of the sublittoral zone. Normally several upright fronds will grow from a common attachment disc. It has a flat thallus with repeated dichotomous branching in the upper part, which makes it appear bushy. It normally has a brownish red colour and may be confused with Mastocarpus stellatus. It has a softer texture than Mastocarpus stellatus, and reproductive structures occur in slightly thickened parts of the thallus, not on small protruding knobs like in M. stellatus. In addition it may sometimes also show iridescence in blue in sunlight.
