I think this to be quartz. It was wet from snow melt. Thanks for the help on ID’s Jason, I appreciate it.

Nice specimen and photo

Xanthoria parietina should be coastal. Caloplaca trachyphylla should be common throughout Utah, especially on granite. (Few things can get good purchase on quartz, usually they follow cracks or impurities.) But this doesn’t look like a normal trachyphylla.

Hmmm. Only fertile Xanthoria/Xanthomendoza on rock in this area should be X. elegans, but that usually has longer, narrower lobes, sort of spidery looking. I don’t know which Caloplaca (aside from trachyphylla) are candidates.

Very nice photo

Is that on granite or quartz? Looks shiny or wet.
