Fistulina hepatica
With a root like stem.

About 6" wide. Looked like it was growing out of the side of this oak
stump.
Underside

When I removed it. I found that it
was growing out of forest litter beside the stump. The cap broke off from
what looked like a root like stem. I managed to get most of the stem out.
Cap with the stem on the bottom.

Cap with stem/root placed in position.
