These were all on an upland rock - I'll have to get into geology next to learn how to identify the different rock types!
1. Caloplaca lactea?
2. Candelaria concolor?
3. Mixed in with the above but looked to be a different beastie....
4. Brown: Acarospora fuscata? White with black: Acarospora umbilicata?



You're liable to be so sick of me and my lichen photos by the end of the winter!
