Summary description (after Hajdu 1995). Thin crust on an Ircinia sponge. Ectosomal skeleton a tangential layer of megascleres carried by a palisade of subectosomal brushes of megascleres. Choanosomal tracts of up to 100 µm diameter run irregularly from the substratum to the surface. Spicules mycalostyles comparatively short and slim, 292–339 x 6–9 µm, anisochelae I with strongly curved shaft with unguiferous upper alae, comparatively robust, 48–62 µm (arranged in rosettes), anisochelae II similar to those of M. (G.) menylloides but larger, 10–13 µm (arranged in rosette-like clusters), anisochelae III palmate with spur, 13–17 µm, and trichodragmas 22–34 x 3–8 µm.
