Diagnosis

Tube-shaped, massive or encrusting sponges with a characteristic muddy surface and polygonal surface pattern caused by a system of thin-walled shallow grooves. Mud particles enclosed in sponge tissue form a dense surface cover and also penetrate into the interior. Spicules relatively low in density, irregularly arranged into bundles which are bound by variable amount of spongin. Spicules may be both monactinal and diactinal. So far, only two species have been assigned to this genus, both widespread in the Indo-West Pacific.
