Hi Dave, thank you! That's what I suspected as well. It is hardwood - but not Oak. It's at the base of an old sugar maple.

Hello, I found the attached shelf mushroom attached to a dying/sick maple in my neighbor's yard in Western MA, USA. 

I'm a novice, and would love some help identifying this. Any nudges in the right direction would be appreciated. 

Thank you!
