This is another ornithocoprophillic Lecanora (see observation 96028, L. straminea)

In Rhoades (2009) – Ryan, pers comm. on one of Fred’s specimens – “Typical of the rather thick, almost squamulose morph found, especially on seashores”

L. muralis is common on sidewalks in Seattle – I’ll post some photos

I have encountered L. muralis identified as Rhizoplaca chrysolueca, and R. chrysoleuca identified as L. muralis

“ornithocoprophilic” is a mouthful!

…lexically, at least, hopefully not literally! :)

I can totally see how a small one of these could be mistaken for Rhizoplaca chrysoleuca. In the desert it forms much more obvious crust-like rosettes.
