This is my first post on your forum.
I have recently taken an interest in lichenized fungi and as such my knowledge is still limited, but I hope that you can help me narrow down the possibilities for this lichen. It grows on an old milestone that is around 300 years old.
K and C reactions are negative, and the apothecium are ~0.35mm on average. I suspect that is is Catillaria chalybeia, but I realise that I might need microscopic characters to confirm this. Sadly I do not own or have access to a microscope (yet).
I have already uploaded photos of the lichen on a danish forum, and will link to that thread rather than upload pictures here. I hope that is ok.

As I said, I realize that this will likely end in an sp., but for some reason I have fallen in love with this lichen and this is my last resort to get an identification.
Best regards
Jonas
