Observation 236461: Lichen P. Micheli

Some small lichens. These larger two I’ve been seeing frequently all over the region recently. If multiple species can be identified, I’ll make a new observation for the other.

My guesses…

I can’t quite decide if the larger umbilicate squamules in the center are sorediate or not. I’m going to guess Peltula euploca if sorediate, Placidium sp. if not.

The much smaller scattered dark brown areoles are definitely some sort of Acarospora, perhaps A. elevata or A. badiofusca?
