It’s not very clear in these photos, but it looks like this has rhizines, not the foamy-spongy black underlay of Anzia. They’re brushy and black, and you can sort of see radiating lines (the underlay in Anzia almost looks solid at this distance, and certainly has no radiating structure). Physcia (e.g., P. atrostriata) would have simple rhizines, so that’s out, too. I’d say H. albicans is your best bet, but I could be convinced otherwise.

dry, very dry
