Known association

Lecanora sulphurea is known sometimes to start off as a parasite on Tephromela atra. This shows that really well.

Colour

Thanks for help with identification. Parasitised grey lichen also seemed to help camera show the greenishness of the central lichen (or perhaps just wishful thinking on my part!)
