Lecanora muralis (Protoparmeliopsis muralis) is a waxy looking, pale yellowish green crustose lichen that usually grows in rosettes radiating from a center (placodioid) filled with disc-like yellowish-tan fruiting bodies (apothecia).[1] It grows all over the world.[2] It is extremely variable in its characteristics as a single taxon, and may represent a complex of species.[2] The fruiting body parts have rims of tissue similar to that of the main nonfruiting body (thallus), which is called being lecanorine.[1] It is paler and greener than L. mellea, and more yellow than L. sierrae.[1] In California, it may be the most common member of the Lecanora genus found growing on rocks (saxicolous).[1]
