This species is a simple, solitary ascidian, with a thin outer covering or tunic. Overall shape is cylindrical, similar to a vase. The body measures 4-15 cm in length, and attaches to the substrate at its base. The oral and atrial siphons are positioned at the anterior end of the body, are slightly scalloped along their edges, and often ringed in yellow and orange dots. Overall, the tunic is smooth and translucent, but distinguished by numerous white or yellow pigment flecks.
