Munseom, Seogwipo­si , Jeju­do, 10 Feb 2002, Lee KJ, by SCUBA , Depth 25m, deposited in the NIBR .

Description. Hemispherical mass, size up to 12 × 9 × 4 cm. Surface, sharp conules covered with thin perforated filamentous membrane. Fine fasciculate fibres appeared under membrane. Several oscules open on sponge surface, 1­5 mm in diameter. Colour pale gray and beige in life. Texture firm and compressible.

Skeleton: Primary fibres loose fascicles, 400-1000 μm in diameter, with numerous perforations. Fasciculate or porous secondary fibres branched out. Bridge form of secondary fibres, 50-200 μm in diameter. Filaments, 3-5 μm in diameter, terminal knobs, 10-12 μm in diameter. Fibres difficult to separate from filaments.
