Thanks to you both, JennyS and AlanS.

I did think that the sulphur coloured Rhizocarpon geographicum ones might both be the same type, as there was just one small area of wall with about 10 specimens all within about 3 metres. I didn't see anything similar elsewhere. I was quite taken by how spectacular the colour looked in the sunshine.

The Belonia nidarosiensis was tucked away at the very bottom of a dry stone wall in an area that would receive little direct sunlight. I only saw that one specimen, and am very pleased to get an ID, since the photo, (even though it was the best I could get), is pretty dire.

Regards
Mike.
