Small sub-spherical sponge (2.5 cm high, 2 cm wide) with root-like structures. Very hispid. Slightly compressible. Color alive and in ethanol is dirty brown. Choanosome is whitish to brownish (alive and in ethanol). Pores and oscule are on opposite sides (in upper part of sponge). The pore area is covered by a sieve and protected by an overhang. There is no sieve over the single oscule (ca 1 mm in diameter), it is circular and surrounded by a fringe of long oxeas. Skeleton (Fig. 17 B–C). Radial bundles of oxeas start at the center of the specimen. Many go beyond the surface, especially on the top surface, very hispid. Triaenes are found only at the surface (Fig. 17 C), either crossing the ectosome or supporting it. Spirasters are abundant in the ectosome, but spirasters and plesiasters can be found throughout the choanosome (spirasters being much more common than plesisasters).
