Note: The species is recorded in the sublittoral along the coast of Norway, but is not very common. Thallus may be up to 1 m long, and axes have irregular or opposite branching. Basal parts of main axes are often hollow. Growing shoots end in a hair. The inner axial cells are substantially longer than wide in main axes, and can normally not easily be seen through the outer, angular cortex cells.
