Oyster mushrooms (Pleurotus ostreatus) growing on a beech tree. The brownish colour suggests that these mushrooms are fairly mature.
This unfortunate beech tree also had a bracket fungus and the first signs of Kretzschmaria deusta at the base of its trunk.

Tooth marks in the bark on a fallen tree branch, probably made by a small mammal such as a squirrel. The whitish marks down the left-hand side look like where the animal placed its lower teeth while it used its upper teeth to scrape the bark. Here and at other places on this log there were signs of small black bobbles near the tooth marks, as if the animal was actually scraping these off to eat them.
The black bobbles may be a Rosellinia sp fungus. The bark, itself, also seem to be unusually dark and may have been covered in a black crust.

The black bobbles look more like Eutypa spinosa than Rosellinia sp.

The whitish marks down the left-hand side could also be claw marks.

A couple of days ago I came across these small black balls on a twig. I think they must be a fungus of genus Rosellinia. See here and here for photos of similar-looking specimens.

From last May, another capsid bug, this time probably Harpocera thoracica (Hemiptera: Miridae).
