what fungi is this?

I'm 99% these are growing out of an stump of Elm I cut up a year or so ago. and these fungi just recently appeared. they are not soft and supple but kind of hard lie a black locust fungi.

It's probably a polypore of some kind. In order to identify your mushroom, we'll need to know the following:

Are the pores underneath a whitish color?
Do the pores change from white to a brownish-black color when you scratch them?
Are the spores brown?

If your answer is yes to all three questions, then you probably have a Ganoderma (Ling Chih/Reishi group.) Check out this key from mushroomexpert.com:

If the pores are grayish-brown, they don't stain and the spores are white, you could have something in the Phellinus igniarius group:

I am 90% confident that this is Trametes hirsuta and 100% confident on having the genus right.

Also compare with Trametes gibbosa.
