Diagnosis
Tethyidae with massive irregular body, ill-defined cortex and surface covered by irregular tubercles and sinuous ridges. Megasclere skeleton formed by subtylostyles packed in winding, more-or-less compact tracts and scattered in the interstices. The tracts branch and anastomose, and generally ascend towards the surface, ending in fans. Microscleres are only micrasters, mainly tylasters, but also smaller oxyasters, filling the whole body. Sediment particles are abundant on the surface and inside the sponge.
