Diagnosis

Lamellate to caliculate or vasiform sponges, arising from a narrow basal stalk. The walls of the lamellae or vase are thin, up to 8 mm thick. The surface is conulose, with small, flush oscules on both inner and outer surface, and covered by a fine, web-like pattern. The fibre skeleton comprises laminated primary and secondary fibres. Primary fibres are simple, cored with foreign debris, and may be slightly fascicular near the surface. The primary fibre skeleton is irregular, in that fibres can be seen running parallel to the surface, before converging towards surface conules. Secondary fibres are branching and uncored. The consistency is dense and pliable, not flimsy and collapsible as seen in Euryspongia species. There is only one described species.
