Need help with this one. Found growing on the bark of a Western Red Alder, Alnus rubra, that had recently been uprooted by surf, it was still anchored in soil. the adjacent lichen were alive and healthy so I suspect there has been little effects from salt water.

After consulting Curtis Bjork, the likely synopsis seems to be that this was originally a Pertusaria, Ochrolechia or possibly a Mycoblastus, but the original thallus has been completely overgrown by another thallus accounting for the uniform colour and texture. The relic texture of the original thallus and apothecia can still be seen beneath the new thallus, although the new thallus has not developed enough to be identified.
