Its range includes South America, Africa, and Mexico, where it grows on bark and twigs.

[1] The lichen has a large leafy (foliose) blue-grey to ash-grey thallus comprising lobes that are 2–3 mm (0.08–0.12 in) wide.

Apothecia are rare; if present, they are initially concave, but become flattened with age, and they have numerous pseudophyphellae on the apothecial margin.

Pycnidia are visible as brown to black dots immersed in the thallus surface; they produce hook-like (unciform) conidia that are 5–7 by 1 μm long.

[2] The upper cortex is paraplenctenchymatous; this means that it is made of a type of tissue in which the hyphae are oriented in all directions, analogous to the parenchyma of plants.
