Aspicilia contorta, or rather Circinaria contorta as is now called, has two subspecies (some authors call them varieties): subsp. contorta and subsp. hoffmaniana. My guess about Aspicilia contorta refers to the specimen at the center of the first photo (and the one in the 3rd) which seem to belong to the subsp. contorta. The other lichen that surrounds it is also an Aspicilia, but I don’t know if it is or not A. contorta subsp. contorta. It is, in general, very difficult to identify lichens, and particularly Aspicilia, solely on the base of photos and without information about the chemistry at least.

I would appreciate your experienced opinion on
