Black pins coming out of Lecanora?
Looks a lot like this: https://www.inaturalist.org/observations/194838523
I've also seen branched pins without an associated dust lichen on Red Oak:

Looked similar to what I saw here:

Probably wrong ID
This obs is for the presumptive lichenicolous fungus causing the pinkish discoloration. Host might be a Physcia sp? See next obs.
Lichenicolous fungi on Parmelia sulcata
Unsure of ID. Found only once on granite bedrock lakeshore.
Could also possibly Phanerochaete chrysorhiza ? But the limited info I could find doesn’t seem to suggest that species also discolors the wood or is quite that dark. Also didn’t see any ‘teeth’ so I’m feeling much more confident about P. sanguinea.
host specific - Cornus alternifolia
Witches' brooms abundant in serviceberry (Amelanchier sp.) along Swedetown Trails. Very noticeable in the winter. The regular leaves have dropped but the infected leaves remain.
Velutinous leaves; huge tree. An odd (and gigantic) Q. ellipsoidalis?

had set on my wool pants to photograph so may see "woolly hairs"
