Observation 21672: Xanthoria elegans (Link) Th. Fr.
When: 2009-05-28
Herbarium specimen reported

Notes: Growing all over limestone cliff. I thought this was a Caloplaca, maybe C. trachyphylla at first, but close inspection shows that the lobes all have complete lower cortex. Apparently it is not usually so pruinose, a sign that it has produced a significant excess of the anthraquinone pigments.
