I say X. weberi

Had a long discussion of specimens like this with Andrew a week or two ago. The pertinent character in the case would seem to be the placement of the soredia: they are covering the underside of the lobes in this specimen. X. ulophyllodes seems to be the only other viable choice, and it is supposed to have more appressed, broader lobes with soredia mostly on the margins.
