Note: The species is relatively common in the subtidal. The thallus has a coarse basal part and is set with thinner and straight side branches towards the top. The side branches form with a relatively narrow angel towards the main axes. During summer the side branches are often shed, leaving only the coarse basal parts. The central cell forms segments with four periaxial cells. The axes are covered with elongated cortex cells, except for the outer ends of the branches which lack cortex cells.
