Diagnosis

Predominantly massive to lobate sponges with punctate surface and often slimy when handled out of the water. Oscules usually prominent on apex of lobes or along ridges. Consistency firm but crumbly. Ectosomal megascleres usually short diactines, often with spined or mucronate endings. Choanosomal megascleres a single size category of short acanthostyles. Skeleton close-meshed isotropic, with 2 or more acanthostyles forming the sides. Microscleres abundant anchorate isochelae in one or more size categories and usually sigmas, often also in more than one size category. Myxilla (Myxilla) species have been reported from Northern Hemisphere and tropical waters, but appear rare or absent in Southern Oceans.
