Xanthoria calcicola


    This foliose lichen is similar to Xanthoria parietina but tends to have a more orange hue and more contorted lobes. The centre of the thallus is densely isidiate with knobbly, convex isidia. Apothecia tend to be sparse or absent; when present the discs have roughened margins.
