[2] It occurs in Europe, North Africa, and South America, where it grows on bark and occasionally on soil in humid, open, well-lit places.

While she noted its resemblance to the leprose genera Lepraria and Leproloma, she placed it in Lecanora based on its chemistry, which aligned more closely with that large genus.

[5] Despite its current classification in Lepraria, Alan Orange has suggested that it belongs in its original genus, Lecanora.

[6] The species forms a cottony and powdery to granular thallus (lichen body) with either a diffuse or defined margin.

The thallus frequently shows patches of exposed medulla, with medullary hyphae mixed among the reproductive structures.
