Holotype, USNM 122891
Description: The holotype is a cushion-like piece measuring 12 x 8 cm. Thickly encrusting, pinkish red with thick, non-detachable cortex. The corrugate surface is interrupted by smooth, circular or oval depressions, 2.5 x 2.5 cm to 4 x 4 cm, dotted by numerous inhalant 0.2–1 mm diameter oscules; some irregular, also smooth and depressed areas are without visible openings. There are two oscule areas on the type specimen, seven on the in-situ-photographed sponge. The elevated ridges and wrinkles, including those surrounding the oscules, are rough to the touch and encrusted by some encrusting coralline algae. The color of the ridges is brown to gray-brown, with some red from fouling corallines, or green from associated cyanobacteria. The smooth, depressed areas, including the oscular areas, are free of epizoans and of clear pinkish-red color in life, proper to the sponge (modified by Cárdenas, from Rützler et al., 2014).
