Diagnosis
Tubular and branched, to globular with cylindrical branching growth forms. Tubes or branches are issued from a common base, have thin walls, and the sponge has a deep central exhalant cavity. Several scattered oscules, terminal if singular. Surface is uneven, membraneous and strongly spined. Ectosomal skeleton forms a tangential irregular network of oxeas between the spines, and appears obscured by them. Choanosomal skeleton exhibits longitudinal, compact, multispicular, fasciculate and anastomosing primary fibres, issuing from the base of the sponge. Between the fibres, large, irregular meshes occur with abundant free spicules. No visible spongin. Microscleres microxeas.
