@dillyd Wow, is this a sculpture representing the earth melting down under the industry year after year? Or just a wooden pillar eaten by moss? Both? Nice anyway hehe
@etc I don't see any P. glauca here, the foliose ones seem to be mostly Parmotrema with a bit of Parmelia sulcata too. Usnea is right for the fructicose one but they are often not trivial to get to species.
