The wood that has been stained red can be seen in the first two photos.

On old Stereum.
Filaments do not turn purple in KOH (see last photo taken under a microscope in a koh solution) - that's one way of distinguishing these fungi from Sphaerostilbella aurifila.
Tooth marks on a Quercus rubra acorn. Not sure what causes the acorns to turn pink.
