My bad – I took a wrong turn here

I stated that lower surface is black. In fact, it’s brown, but when choosing between “black” and “pale” in Thomson’s keys I chose “black” because it seemed closer to that for me. Jim Bennett pointed out that parts of the underside are blackish, but some other parts are actually pale brown, and in that case I should take “pale” road when using keys. Anyways, it’s X.cumberlandia then.

No isidia. Lower surface black. Could be either X.angustiphylla or X.hypofusca

In fact, it could be both. The first photo, with lots of apothecia, is more typical of the former, and the one with a ruler next to lichen thallus looks more like the latter. Will determine when chemistry is done. The morphological distinguishing factor – the lobe width – is unreliable, in my opinion.
