Wood ear is called that because it grows on wood, not soil. So, definitely not that. Some random cup
fungi. It doesn't have anything that makes it particularly distinct. It's not a bright color, and you haven't mentioned that it smells like anything special. Lacking those, I'd be wary of eating anything that was ID'd over the internet. If you do a spore print and consult a few guide
books, or may be able to find out what it is.
