Sponge:
Thin to thick, encrusting up to 1.6 cm thick with more or less flat surface.
Consistency: lightly compressible, friable.
Surface: nodular, ridged. Ridges hispid and delineate shallow grooves.
Oscula: numerous, 1.0 - 4.0 mm across, round to somewhat irregular with slightly raised lips. In the larger specimens, Oscula tend to be within surface grooves..
Color: Alive: Yellow-light orange, buffy citrine. Preserved: Light tan.
Spicules: Megascleres:
(1)Styles-Acanthostyles with few spines:
169 -202-221- 251 um.
x 7 -8-9- 10 um.
(2)Tylotes - Subtylotes:
137 -166-185- 260 um.
x 4 -5- 6 um.
Microscleres:
(1)Arcuate Isochelae:
21 -27-29- 34 um.
(2)Sigmas:
30 -49-54- 64 um.
(3)Forceps:
5 -8-9- 11 um.
Skeleton:
Ectosome: Dense, crust-like mass of bound Tylotes - Subtylotes parallel to surface.
Choanosome: Reticulation of wide tracts of Styles with overlying looser reticulation of random Styles and Tylotes.
Distribution: Central to Northern California.
Depth: Intertidal.
Note: May be confused with Lissodendoryx firma.
