UV Fluorescence in Lichens

I collected some different lichens during a conservation morning at Paxton Pits and photographed them with a macro lens using a UV torch. The UV light is absorbed into the subject and visible light is re-emitted at different wavelengths giving beautiful colours for with Xanthoria parietina (white light images on the right to compare) . The last two lichens (Usnea species and ?genus) did not fluoresce
