Megascleres: Styles to Oxeas with intermediates.
Microscleres: Palmate Anisochelae, 3 size classes; smallest (very small), are J-shaped, with the foot equal to a small hook.

? Mycale (Oxymycale) sp. 2 [of Lee]
Sponge: Large, thick, conical with vertical openings on side. Consistency: firm. Fragile when wet. Surface: rough. Oscula: abundant and elevated to 2 mm in fresh material, elevations not seen in dried specimens.
Color: Preserved: Tan to grey.
Spicules: Megascleres: (1) Styles to Oxeas with intermediates: 570 -671-730- 836 um. x 15 -18-22- 25 um. Longer spicules (to 1760 μm) reported in fresh material only Microscleres: (1) Anisochela-J-shaped with the foot equal to a small hook: 15 -18 - 22- 34 um. (2) Anisochelae: 36 - 44 - 47- 60 um. (3) Anisochelae: 60 - 94 -117- 135 um. (4) Sigmas: 10 -19-22- 48 um. (5) Raphides: 12 -22 - 61- 99 um.
Skeleton: Parallel tracts to surface and loose reticulation.
Distribution: Southern and Northern California.
Depth: 91 to 256 m.
Originally reported as Mycale paradoxa by Bakus & Green, 1987. Type of latter shown to be Myrmekioderma contaminated with anisochelae from Mycale bellabellensis. Somewhat similar (?) to M.lingua from Pacific Northwest.
