Diagnosis

Thickly encrusting, massive or branching growth form, often with a marked conulose surface and a distinct net or weblike surface pattern, interconnecting between conules. Species with heavy intra-mesohyl detritus are not conulose. The skeleton consists of a regular, usually rectangular arrangement of concentrically laminated primary and secondary fibres, with primary fibres oriented perpendicular to the sponge surface. All fibres are axially to fully cored (Fig. 1B–E), although this may be in the form of scattered fragments rather than a dense core. Primary fibres are also pithed though this is usually obscured by the coring material. The sponge is soft and compressible, sometimes made fragile by large amounts of sand etc. incorporated into the sponge tissue. There is only light collagen deposition in the mesohyl, and the sponges are histologically simple, with few secretory cell types present.
