I was intrigued by the black masses on this twig, as I can't make out the thallus. There seems to be what looks like Lecanora which might be associated with these bodies?
No identification made yet.
No interactions present.
Some lichens have thalli that are evanescent or immersed in the substrate and not at all obvious.
There are perithecia here - the black, rounded, wart-like structures to the right in the first photo. To the left, associated with the grey filmy thallus, are apothecia. Arthonia punctiformis is a guess for the latter, but microscopy is always preferable to guesswork (especially my guesswork).
The perithecia in the left of the second photo could well be Arthopyrenia analepta.
The black apothecia on the whitish thallus in the centre of fifth photo might be Lecidella elaeochroma or possibly Amandinea punctata
