If you're asking for mushroom identification knowing what region/general area this picture was taken would help narrow down the possible species.

Sorry, its western Quebec. In pine forest
In that case I agree with the other comment that's saying Dryad's Saddle/Pheasant Back. It's a likely candidate based on the cap and region at least.
The new comment that popped up as I typed this saying you should include the underside if possible is also correct. The gills help a lot in identification.
Also a picture of the underside and a cross section can be really helpful too.
Looks like a Dryads Saddle
Yep, it does look like pheasant back.
It looks like a tree stump with some fungus and moss growing on it. Hope that helped!
I naturalist is probably better for identification as it has the location option and a heap of fungi connoisseurs waiting to ID
