The focus here is on the lichen.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Seems to be all sorts going on here, is it the tiny pink fungus that is the parasite? have you more pictures of the underside of the big floppy fungus?
I believe the pink blob is one of the lichenicolous fungi mentioned on Alan's page for this lichen (assuming I've got the right species):
At the time I didn't give the black fungus much thought, and didn't look at the underside. Now I wish I had because I'd like to know what it is.
Yes, the pink blob looks to be Illosporiopsis christiansenii, little recorded but evidently frequent especially on Phycia and Xanthoria.
Yes, the dark brown fungus looks interesting, I suppose an Exidia or Tremella?
