Thank you Jeannie. That is actually pretty useful advice. I did eat a little bit of it after cooking it. It had a nutty (not crazy) flavor. No bruising when I sliced it.
Are these edible. I found these under an oak tree on the ground growing out of the moss. The underside of the cap looks like a sponge and the cap looks like a hamburger bun. The stem was solid and the flesh was white when sliced.
