Diagnosis

Thickly encrusting, massive, or globular sponges. Surface irregularly hispid. Cortex conspicuous, formed by a crust of sterrasters with a layer of euasters in the outer zone. Cladome of the triaenes located at the cortex. Megascleres (oxeas and triaenes) radially arranged at the peripheral zone of the sponge, oxeas more disorganised in arrangement in the interior. Inhalant and exhalant orifices arranged in clusters under a sieve of the cortex (cribriporal).
