rhizocarpon geographicum
Growing on a North-West facing wall (but facing a small wood so probably even more sheltered from the elements). Pics 1 and 2 show the lichens growing on the top of the wall (so exposed to direct sunlight, rain, wind etc) whilst pics 3,4 and 5 are of the lichen that probably gets no direct sunlight etc. My theory is that they are the same species but the lack of light has caused it to grow differently and with a green tinge??? I think the orange patches in pics 1 and 2 are to do with the minerals in the rock. Any pointers/corrections would be awesome! thanks
cs2 - currently have a sample of the one in pics 3,4 and 5
