Poroid

I think this is the underside of a Blushing Bracket fungus but, in the absence of my fungi books (in storage), I'm not completely sure of the identification. Foolishly I didn't stop to look at the upper surface which might have distinguished Blushing Bracket from Common Mazegill and some other possibilities. However, I note that the slot-like pores don't merge to form a maze as in some other species.
