Do you recognize this fungus?

Question

It grew alone on the cut surface of a firewood log (tree type unknown) and is shaped like a slightly deflated blimp, with the long axis parallel to the wood's surface. It is 1.5 inch long and 0.5 inch wide at its widest point, is black or v. dark brown and has a pebble-like finish with grain size about 0.05 inch. It is pretty tough and is undamaged, seems hollow, has no features like gills, and is attached to the wood via a curved stem at one end. (Toughness, color and finish may have been different when it was younger.)

I've browsed several excellent fungus websites but haven't seen anything resembling this, even when only looking for the shape.
