Yellow lichen is Acarospora

Something close to A. socialis, but there are several species that are similar. I’m not sure the grey one is Physcia, but don’t have any other suggestions for it!

Two species?

Thanks for having a look J-Dar. These are indeed on rock, at the windy peak of one of the Granite Mountains.

I had assumed the bright yellow-green lichen was a different species. I’ve added an image that better shows the yellow-green.

Looks like a contorted Physcia

with the background appearing to show a yellow Acarospora, and you being in the “Granite” Mountains, we can guess its on rock. If we assume Physcia is correct, the substrate can narrow you down from 15 or so species to just a couple.
