Skeleton:
Central spicular axis with branches leading to support lateral projections.
Distribution: Southern and ? Northern California.
Depth: Subtidal to deep water, 59 - 463 m.
Note: Reported in California by Bakus & Green, 1987. This species needs review as it is possibly Asbestopluma occidentalis (Lambe, 1893). A. occidentalis is considered a valid species in the Pacific Northwest.The latter was synonomized with A. lycopodium by Koltun, possibly in error. Bipocilli are not reported by anyone but Bakus & Green.

Note: This species was described by de Laubenfels as Wilsa hymena on the basis of a single,incomplete, and contaminated specimen growing on a hexactinellid sponge. Based on the de Laubenfels type, its identity as Wilsa would remain in doubt. However, an uncontaminated specimen which matches most of the original description has been discovered and supports its transfer to Forcepia. [See page 151B for details.] The spicule measurement listed above are those originally given by de Laubenfels, 1935. They are inaccurate and serve only as a comparison to the description given on page 151B.
