Areoles (from tiny to 3 mm) surrounding dark reddish-brown to black apothecia (fruiting bodies) are both highly variable in shape and size, and variable in size relative to each other.[1]: 220 [2] Measuring 0.1–1 mm, the apothecia range in size from small dots on the areoles to almost as wide as the areole.[1]: 220 [3] They can be pointlike to round, polygonal to stellate radiating fissures, and one to many per areole.[2]

Areoles may be cracked on the surface, especially toward the apothecia.[1]: 220 

Lichen spot tests are all negative.[1]: 220 [2]
