On dead buttonwood (Conocarpus erectus) and christmasberry (Lycium americanum) in opening.

I’ve become unconvinced of the ID of these things. The chemistry is virtually indistinguishable (at least without TLC), the only differences I know of come from Brodo’s Lichens of North America:

R. stenospora — flatter, more striate
R. montagnei — terete, less striate

These photos show some parts are clearly not terete.
