The lichen has lobes with distinctly round, laminal soralia. It contains lichexanthone, a lichen product that causes the cortex to fluoresce bright yellow when lit with a long-wavelength UV light. A chemical spot test of the medulla with an aqueous solution of potassium hydroxide (i.e., the K test) is partly K− and partly K+ (purplish).[3]
