I agree that photo probably represents Climacocystis borealis

Having just vetted the identifications at the Oregon Mushroom
Show (October 18 2009), I discovered I had mistakenly applied the identification “Tyromyces chioneus” to a perfect specimen of Climacocystis borealis (chalk that up to the miserable show lighting conditions). Micro confirmation back in the lab reveals the specimen to represent instead C. borealis (clamp connections, small ellipsoid/elongate basidiospores, monomitic constructions, and the oranging to yellowing soft construction. Referring to Dan Wheeler’s comment: C. borealis has been referred to Spongipellis. thus his observation in no way negates the taxonomic identification of the specimen shown.

Possible Spongipellis. Too far away and not focused well enough to be sure.
