“Noblesse oblige” and so I uploaded the promised photos.
Thanks again, Jason.

So no worries about uploading images. Just wanted to make sure you knew about the possibility of Ramboldia. I get lazy and if I only know of one species that looks like this, I would eventually grow tired of measuring spores and probably miss that rare specimen that was actually something new and exciting. What a tragedy that would be!

I have no standard procedure,

but in this case I did check the spores. Later I will upload some photos from microscopy. Meanwhile, I looked to some photos available of Ramboldia and saw there are some similarity with those of Caloplaca, as you mentioned. Particularly, some species, including R. haematites, R. heterocarpa and R. russula (and maybe others), can be easily mistaken for C. ferruginea. So, something to keep in mind …
Thanks, Jason, for the warning.

Do you always check the spores?

I see you have in at least once case, and of course it’s as you say, a Caloplaca. …But these are so eerily superficially similar to Ramboldia that I wonder if maybe some of them may have acicular spores instead?? At least one species of Ramboldia is known from Britain, so it may not be completely out of the question. Just curious.
