Surface corrugated and conulose. Oscules small. Ectosome consists of tangentially placed styles supported by the distal extremities of the main fibres ending in the surface. Dermal membrane, thin and transparent. When dry the dermal membrane sinks down following the contour of the subdermal cavities. Subdermal cavities extensive ; width, 1 to 1.5 mm. Endosome, crumb-of-bread-like. The skeletal arrangement is irregularly reticulate. In the deeper parts the styles get arranged in a confusing manner, and as they come close to the surface may get arranged in bundles of 3 to 4 spicules in cross section. Smooth styles echinate the spicular bands in groups. Spongin sparsely present. Towards the surface, the reticulation becomes quite well defined ; polygonal or irregular in outline. Tornotes are found either singly or in groups both in the ectosome and endosome. It has smooth echinating spicules.
