Porpidia flavicunda
The bright orange of this crustose lichen's thallus contrasts with the blue, silica-containing rocks it grows on. The apothecia are charcoal-colored. Moss frames the periphery.
Seen on an alpine trail in Ross Lake National Recreation Area.
ID is not definite (and cannot be confirmed, unfortunately) due to the presence of multiple species in the region and lack of microscopic/DNA information.
