11. Ircinia radicula View in CoL n. sp. ( Fig. 11)
Type specimen. Holotype (NIBRIV0000801339), Korea: Duokyeo, Gageodo, Heuksan-myeon , Shinan-gun , Jeollanam-do, 20 Jul 2007, Kim HS, by SCUBA diving, depth 15 m, deposited in the NIBR.
Description. Thick massive sponge, size up to 7 × 7 × 9 cm. Surface have filamentous membrane, distinct conules, and sand patch, but not sand crust. Oscules, 3-5 mm in diameter, opened at protruding mammilated conules. Colour in life dark grey. Texture, firm and compressible. Skeleton: Primary fibres fascicles, over 1,000 μm in diameter, very complex massive fibres that are radially arranged. Primary fibres near surface have sand patches ( Fig. 11F). Secondary fibres showed irregular branch type like roots, and wide fibres like plates, 200-450 μm in diameter ( Fig. 11F), bridged secondary fibres, 100 μm in diameter. Filaments, 5-7 μm in diameter, with terminal knobs, 10-15 μm in diameter.
Etymology. This new species name radicula is named after the complex massive primary fibres which arranged radially with sand patch.
Remark. This new species is sparsely distributed. Specimens had sand over the sponge surface. Massive primary fibres are very complex and radially arranged with sand patches at near surface conules ( Fig. 11D).
