Diagnosis
Thickly encrusting Polymastiidae, spherical or cushionshaped, always with papillae. Skeleton composed of radial tracts of principal spicules between which free spicules are scattered. Ectosomal skeleton composed of at least two layers, the superficial one is a palisade of small tylostyles, the lower layer is made of intermediary spicules, tangential to the surface. The principal spicules can be tylostyles, subtylostyles, styles, and strongyloxeas, intermediary spicules are most often tylostyles, and ectosomal spicules are always tylostyles.
