This autumn has been really great for fungi. The forests I have visited on my recent travels, in Hungary, Poland and Serbia, have been full of toadtools and musrooms. This fresh Hoof Fungus Fomes fomentarius (this photo taken in Poland shows why it is called HOOF fungus) was about 20cm across, but they can grow to well over 30cm across. When Hoof Fungi age they darken and harden. They usually grow on beech, at least in this part of Europe. It is not edible.
