Could go either way

Can’t quite make out the shape of the cephalodia (black dots on the surface), but they look like they could be becoming flaky enough to be P. britannica. The thick broad smooth lobes with that distinctive white rim are perfect for P. aphthosa… but can be shared by P. britannica. It’s definitely wet enough in Skagway to be P. britannica.

… Wait, apparently P. aphthosa has not been recorded for this area. See the landmark paper by Spribille et al:

Spribille, T., S. Pérez-Ortega, T. Tønsberg & D. Schirokauer. 2010. Lichens and lichenicolous fungi of the Klondike Gold Rush National Historic Park, Alaska, in a global biodiversity context. The Bryologist 113(3): 439-515.
