These brown algae only grows to height of 8-12 cm. The color is yellow-brown, but they turn almost black if they dry out. It is branched in two-splits. The stipe has no bladders, but has a swollen appearance, due to a distinct channel which holds moisture. This is essential for the plant to survive high up in the tidal zone. The surface is gnarled.


This algae does not survive if it is constantly submerged. Therefore, it is only found high in the tidal zone. It thrives both on wave exposed and sheltered locations.


It seems to be confined to the North-East Atlantic Ocean, from the Faroes and Norway to Portugal.
