The plants have a filamentous holdfast and triquetrous main branches. The vesicles are oblong to elliptical. The wing-like leaves with serrations on the margin run from the main branches. The color changes to a dark brown when dried. The plant grows on rocks in lower intertidal zones along shorelines with frequent gentle currents.
