[of Lee] |
Sponge:
Encrusting to 2 cm.
Surface: granular to superficially smooth.
Oscula: with tiny rims, less than 1 mm across.
Color: Alive: Gold, cinnamon brown, yellow, buff.
Spicules: Megascleres:
(1) Styles-Acanthostyles:
149 -182-190- 210 um.
x 5 -8- 10 um.
(2) Tylotes -Subtylotes:
135 -168-182- 200 um.
x 3 -4- 5 um.
Microscleres:

Skeleton:
Ectosome: Dermal membrane under which are thick palisades of Subtylotes, mostly perpendicular to the surface.
Choanosome: Thick, dominant reticulation of bundles of 3-5 Styles- Acanthostyles. Tracts only occur very near the palisades of Subtylotes.
Distribution: Central California.
Depth: Deep water.
Note: Easily confused with Lissodendoryx firma. Could be a variant of that species.
