Recognized by sight: The common species in the sierra is L. sierrae, and I’m not sure how (or if it’s possible) to distinguish the two by sight. The best character is that L. muralis s. str. has distinctive conical bundles of hyphae growing down from the cortex, penetrating and interrupting the algal layer. Various authors talk about differences in color of the thallus and apothecia and presence of pruina, but they don’t seem to be consistent. On-line pictures may or may not be correctly identified or helpful, either.
