The nine to eleven broad to flat, blunt ribs are clearly furrowed across and divided into low humps with a chin-like protrusion. There is no central spine . The five to seven stiff radial spines are up to 1.5 inches long. One of them is directed downwards, the rest sideways. When dry, the radial spines are lime-white. Moist radial spines are yellowish and brown at the tip and base.
