probably rock

I think all of my lichen photos from this spot came from a small rocky outcrop at the top of a knoll, and I don’t remember any wood in that area at all, so you are probably quite right about this lichen growing on rock.

I’m not sure…

It might be because I’m just jealous because I’ve been looking for a fertile Hypocenomyce scalaris for years and haven’t seen so much as a single apothecium :)… But I’d say that this looks more like a Lecidea atrobrunnea type thing. For one, it looks like it’s growing on rock, though I can’t really tell — H. scalaris should be exclusively on bark and wood. Also, see how some of the apothecia are angular and inset between the squamules? That strikes me as a Lecidea thing, despite the otherwise unusually convex apothecia. Alas, a C test would be really telling.
