Note: The species grows in the intertidal and is common on waveexposed shores in most parts of Norway (except the inner Skagerrak region and the northernmost part of Norway). It normally has a biennial life-cycle. The small, disc-like vegetative thallus produces up to 2 m long receptacles during spring and early summer, which are shed in the autumn.
