Or am I not understanding this correctly? :)

Lichenothelia suggested by Pat McCarthy and confirmed by Kerry Knudsen

Thanks for looking Jason. As in my message to you my posting on Flickr https://www.flickr.com/photos/29750062@N06/15057631792/ elicited a comment by Pat McCarthy that this is Lichenothelia, and that Kerry Knudsen would be interested as he is working on a revision of that genus. Kerry confirmed the identification and I have sent a specimen to him.

But I would personally start in Rhizocarpon if I found this in the American desert.
