Toft Wood Lichens

The high winds have brought down lots of branches from the trees in the wood, many encrusted with Lichens. Here some focus-stacked images first under normal white light and then under UV light. The first twig has a number of different species including Xanthoria parietina (bright orange under UV), Parmelia sp (grey green), Lecanora chlarotera etc. The second pair of images demonstrates how the UV fluorescence shows the margins between the species: here Lecanora chlarotera (brown caps),   Lecanora albella (pale cups), Lecidella elaeochroma black fruits and margin,
