Description
Color: Colour (in spirit) pale greyish -yellow

Sponge irregular, compressed, lamello-digitate; only 3 millimeters or 4 millimeters. In average thickness, with a maximum length of about 45 millimeters. Surface granular in appearance and minutely hispid, fairly smooth but uneven; margins rounded.
The main skeleton consists of a dense and very irregular reticulation of styli, mostly scattered singly, but occasionally collected in loose strands. The dermal skeleton is formed of a thin layer of small slender oxea, lying tangentially to the surface and very irregularly scattered.
Spicules: (1.) Styli; usually fairly stout and slightly curved or crooked (especially towards the base), narrowing slightly to the base, which is evenly rounded, and tapering gradually to the apex, which is sharply pointed; size, when fully grown, about 0.95 millimeter by 0.02 millimeter. but numerous smaller and more slender forms occur which are apparently young.
Oxea slender, sub-fusiform, slightly curved or angulated once or twice, sharply pointed at each end; size very variable, averaging,say, about 0.2 millim. by 0.0055 millhn. These spicules occur chiefly at the surface of the sponge, but are also found in the interior.
