Diagnosis

Massive, tubiform, cushion-shaped or encrusting sponges, with a strong tendency in several species to form fistular outgrowths. Oscula usually large, not numerous. Colour orange, pink, purplish or white; in some species there is a two-colour combination of a whitish transparent ectosome and a darker coloured, purple or orange choanosome. Consistency relatively crisp and brittle, only slightly compressible. Spongin absent or very scarce, at the nodes of the spicules. Ectosomal skeleton of the same structure as the choanosome, usually very loosely overlaying the choanosome, from which it may be separated by extensive subectosomal spaces. Choanosomal skeleton a subisotropic, somewhat confused reticulation, commonly intercepted by many choanosomal spaces. Megascleres usually acerate or hastate oxeas, reaching substantial sizes in some species. Microscleres, if present, microxeas or sigmas.
