You did a great job collecting all this stuff, which would be enough for a few posts. I am impressed )
Let me make a few suggestions about mushroom photography. Of course, one photo is not enough for accurate identification, so only assumptions
No. 2 looks like a white milk mushroom (Lactárius résimus)
No. 5, 13 may be mushrooms (Lactarius deterrimus)

6 turkey tail (Trametes Versicolor)

No. 8 white row (Tricholoma album; radovka-belaa) white knight))
And of course I'm impressed with this oak tree. Unfortunately, there are few such trees left in Europe.
Have a good weekend
