I not too sure but here goes;
Top left, flat orangy brown shelf type bracket, I think maybe has odd long shaped pores (I am using my scooby sense to view them
)and is maze gill fungi (Daedalea quercina). The sharpness of the edge combined with the lumps on the surface there is also something about the the colour to which I base my guess on.
The bottom corner has that caracteristic shape of proper hoof fungi fomes fomentarius. There is a closely related fungi called Fomitopsis pinicola which has a larger orangy band around the rim and is more likey to grow on pines but will grow broadleaf as well. They both leave nobbly scars on the tree and fissures in the bark where the wood becomes visable underneth. The other tinder fungi (phellinus) are flater shape generally. All on them have white spores.
Ganondermas (artist fungi etc) cover themselves and the tree around with a brown dust (lots of spores) In my experiace they also reck the tree they are growing on causing very pronouced and obvious rot at the bottom of the tree. The pores underneath are very tightly packed together as well.
