that the black prothallus in that one photo may have more to do with the species it’s interacting with. If it were intrinsic to this species then you would normally see it around all thalli, especially ones growing on bare stone without any competition.

You posted another like this recently — a Lecanora like crust with black apothecia. I’m hoping you’ve got a Tephromela atra in one of these! But there are black-eyed Lecanora, too…

Thallus looks somewhat like observation 204765

It’s more bumpy, but the surface structures look similar. The other concern is a black prothallus (seen in bottom picture) versus white prothallus in observation 204765
