Lecanora cinereofusca is a species of corticolous (bark-dwelling) crustose lichen in the family Lecanoraceae.

Beaded Rim-lichen (Lecanora cinereofusca) is declining primarily due to air pollution and habitat degradation affecting its specialized substrate requirements. Urban development and industrial activities have reduced suitable habitat and altered air quality conditions necessary for this sensitive lichen species.
