Porpidia Lichen

Porpidia crustulata

Description:

They look like spirals or bullseyes. Loosely covering this boulder. Could also possibly be Rhizocarpon concentricum. Not sure they can be told apart macroscopically, but this one doesn't have a very cracked thallus which is why I was leaning towards Porpida

Habitat:

On a boulder near a river in White Mountain National Forest
