Fomes fomentarius
This sombre fungus usually appears as a solitary specimen but occasionally two or more tiers are produced. On standing timber this bracket sometimes gains a hold in clefts in the trunks of older trees. Annual layers of tubes build up to produce a large hoof-shaped structure 10 to 40 cm across and up to 20 cm deep at the centre of the attachment line. After the first three or four years, brackets increase steadily in thickness but do not grown much in diameter - hence the resulting hoof shape. The upper infertile surface is various shades of grey, often with a brownish growing zone towards the outer edge. The lower fertile surface is white or greyish, turning slightly brown when bruised. Inside the fruitbody the flesh is hard and pale brown, while the tubes are pale grey-brown at first but become darker brown with age. The pale spore-bearing surface is noticeably softer and has minute pores typically spaced at 2 to 3 per mm.
Fomes fomentarius is parasitic on broadleaf trees, particularly birch and less often beech and sycamore, but continuing to grow for many months as a saprobe on dead trunks.
Spotted in rural area of Deventer, Holland. (sources:see reference)

Thank you for the kind comment, Neil. I am not sure but I think the well defined margin might have to do with the age of the fungus. The fungus in photo 3 consisted of one layer and was only just in the process of forming a new layer, so I'm assuming it is a fairly young specimen. With age comes wrinkles and uneven skin tone, perhaps this is also true for the tinder fungus :)
Now that is a beautiful spotting, Jae. Gorgeous specimens. These large fungi are one of my favourite species. The third photo is interesting because the margin and pore surface seem to be clearly defined and separate. Is that common with this species?
