I was totally stumped; Trevor Goward had never seen this species fertile before; but Ernie Brodo was very confident:

“I think that Trevor is right. It looks like a richly fertile Physcia
millegrana
. It’s an easy species to identify when it’s on bark, being
the only one with granular-sorediate (‘blastidiate’) lobe margins.”

Please note that it is wet in this photo; it will probably look significantly different when it dries out. Nice observation!
