Sometimes we are so used to some species that we neglect their common form. The one shown in this observation is one of the most common for Xanthoria parietina here, when it grows firmly attached to twigs and shrubs. You can seen a similar form in observation 101511, which ironically is not devoted to this species itself but to a lichenicolous fungus.

This time you can believe it, though… :)

This thing looks odd for X. parietina. I’m used to seeing it flat against the substrate without any ridges or wrinkles. You have a few other Xanthoria in Europe that we don’t have in America (X. calicola, X. aureola, X. ucrainica)… They don’t look any more likely, granted. But Zaca has at least seen some of these other species. Also I’ve only seen X. parietina itself a few times; I think Zaca has much more experience with this species.

Don’t believe everything you see written,

Jason knows more about lichens with eyes closed than me with your eyes open. But in this case, if I had to bet it would be on X. parietina.

Zaca knows these better than me.
