Branching pattern

Thallus can be up to 2 m tall, the axes are somewhat flattened and lack midrib. It has irregular or alternating branching. The gas vesicles (some indicated by arrows) sit on short stalks, are elongated and divided in compartments ("pea pod structure”). It is common in the upper part of the subtidal and in rock pools, and has a stunted form in rock pools. It is monoicous and fertile during spring and early summer.
