Probably at least one or two other species of Xanthoria on this tree if you looked closely, but everything I can see in the photos is X. fallax. It has distinctive-looking soralia where the upper and lower cortex separate and the medulla in between breaks down into soredia. It’s often described as “birds nest soralia”. This is a fair example of it, but Chris Parrish (and maybe other users) have some particularly excellent photos of this species on MO that might be worth looking at.

[See observation 50364, for example.]
