Weird Lichen

This is one of the weirdest lichen I’ve ever seen – it seems like a mixture of several species. Especially stand out are the white and tan forms, sometimes growing side by side. I was under impression that another species, Rhizoplaca chrysoleuca, was involved, especially since some authors claim the two species often form intergrades (and some claim it’s the same species – one is just a form of another). But Jim Bennett at UW-Madison identified this material as just one species – R.subdiscrepans. Check out the “cabbage”-like structures seen in some photos – what the heck is that?
