Note: The species is found along the Norwegian coast in sheltered areas. It forms dark red bushes, normally with more than one main axis from an attachment disc, and the axes are often relatively sparsely branched in the lower part. It has segments with 12-16 periaxial cells and no cortex cells in the upper parts, while the main axes form some cortex in the lower parts. The attachment rhizoids are cut off from the periaxial cells.
