Sponge:
Frondose, Stalked. Stalk 1/3 of length.
Surface: superficially smooth, finely hispid.
Oscula: No pores or oscula visible.
Color: Preserved: Tan. Alive: possibly Brick Red.
Spicules: Megascleres:
(1) Styles:
1125 -1765- 2200 µm.
x 18 -25- 34 µm.
(2) Styles:
280 -470- 680 µm.
x 8 -16- 31 µm.
(3) Acanthostyles -points acanthose:
340 -433- 480 µm.
x 23 -27- 36 µm.
Microscleres:
(1) Stylote Rhaphides:

No details given.
Distribution: Southern to Northern California.
Depth: Subtidal to deep water, 14 to 89 m. See 33B.
Note: Description largely as given by Green & Bakus, 1994. Note differences in long Style and Rhaphide measurements from de Laubenfels description below (33B). Raphides could be juvenile megascleres? Was Hemectyon hyale.
