I don't think you are supposed to fry eggs that long mate ..........
but seriously , as a fungus it looks well past its' sell by date , specimens are best identified fresh
Some basics on ID ing them include checking to see if they have gills or not , stem and presence or absence of a ring are also important. Colours of the underside would be helpfull too. Smell well noted
The theory of a fox carrying it baffles me a little , I can not see a lot of damage, might I suggest it fell off the tree it was growing on ?
I dont like the idea of posting a pic on the web to try and ID a fungus because of the many (often omitted in descriptions) variables in the way they grow and the places they grow in.
Sorry for not being more helpful but in the spirit of bushcraft........learn to help yourself first (in this case by giving as much detail as you can possibly gather)
Even then any ID over the internet is hardly conclusive or safe
