Shape of the sponge resembling a broccoli floret. Skeleton irregularly reticulate with very thick spicule tracts; at the surface, echinating spicules present. Spicules acanthostyles with very few spines at the rounded ends, 260–430 x 15–30 µm, tylotes 250–300 x 8–10 µm, arcuate isochelae about 25 µm, and sigmas 20–70 µm.
