A lichen characterized by blueish grey-white to green leprose thallus with a cottony margin and the presence of gyrophoric and porphyrillic acids. Pale-coloured specimens resemble Lepraria species and it also has similar ecology. Psilolechia leprosa grows on rock substrates enriched with metals, mainly copper, on both natural and anthropogenic stands, such as mine entrances or spoil piles composed of larger stones. It prefers shady and humid places that are protected from rainfall. It is a suboceanic lichen, mainly distributed in western Europe. It is rare in central Europe. The species has less than ten known localities in the Czech Republic, which are all of anthropogenic origin.
