A relatively thin, white-ish encrusting mass, with darker veinous canals radiating from low conical excurrent openings. This apparently undescribed species is assumed to be a form of Clathria demonspongia due to its general visual aspect.

Unlike other Clathria like White Encrusting Sponge (q.v) and Peach Encrusting Sponge (q.v.), this specimen features darker radiating canals rather than white ones.

Note: Due to its clear repeated star patterns, this specimen could be mistaken for a Star Encrusting Sponge (q.v.). However, one of the features of the latter type is its relatively independent network of branching canals that seldom connect with that of a neighbouring network.
