This sponge is greenish- yellow, and its colonies consist of attached chains of exhalent pores. The pores are spaced along the tops of the ridges.

Apertures are lighter in colour than the main body, with a circular membranous ring at the top of each.

The surface is covered in small bumps, not in ridges as is the case with the other species shown here.
