I assumed you were right at first, but the more I look at this, the more intrigued I get. I can’t find any soredia. There are extremely few pseudocyphellae. It looks almost phyllidiate on the interior margins. Those slender branches are also striking. I think this is the rare oldgrowth species Parmelia pseudosulcata. I’ve never seen it, but it fits the description, at least. Cool!
