Reddit reviews Rocky Mountain Lichen Primer

Hard to say- you have got a lot of lichen species in that photo, and you often need some pretty minute, clear details to even get to the genus level with lichens. That being said I can say with a reasonable degree of certainty that you've at least got some Aspicilia caesiocinerea, some Rhizoplaca chrysoleuca, and something like Xanthoparmelia Coloradoensis. If you want to get going on learning to ID lichens yourself, I recommend A Rocky Mountain Lichen Primer. If you want a seriously deep-dive inventory of lichens in the state, check out the list so far on CNALH.
