I hope you're lichen these photos (i'm so sorry)
Buying a new lichen field guide and then going out to try to identify as many as possible was amazingly humbling. I'm gonna need someone to hold my hand through this process, because it's more difficult than I thought. If you are good at this, I need your help--it might be good to know these are all on Great Blue Hill, on a wet day. Ready? Here

Are you aware of this blog: New Hampshire Gardens Solutions? He has a lot of material on lichens (and lists that guide as one of his references.) I absolutely adore his writing style - I wish he were my next door neighbor.

Dear Jef,
Sara asked me to help you with lichen ID. I’m a southern lichen guy, so a northern lichenologist might be able to do something with some photos that puzzle me. For instance, the crusts in photos 1, 5 and 6 are mysteries (and I think you should be cautious about calling Photo 1 Porpidia crustulata, as there are several possibilities). So take all this with a grain of salt, but here are some possible IDs:
Photos 2, 11 and 15 are all Porpidia albocaerulescens.
Photo 7 is a Lecanora sp.
I think you’re right on 3 and 4.
Photo 8 is a Physcia, possibly P. aipolia.
Photos 9, 10 and 14 are Lasallia papulosa.
Photos 12 and 13 are Umbilicaria mammulata.
Photo 16 is of Lasallia and Umbilicaria together, and it took this southern boy a while to realize the white fluffy stuff is snow, and not a lichen reproductive structure!
Hope this helps. Feel free to contact me directly, mhodges1957@gmail.com
Yours-Mal Hodges

Your 9th photo is of toadskin lichen (Lasallia papulosa). You also have two or three photos of this one.
Your last shot is of rock tripe lichen (Umbilicaria mammulata).
It takes a while to learn how to identify lichens, but you'll get there. It's a fascinating subject!
