Overview

Lecanora impudens is a species of crustose lichen in the family Lecanoraceae. It was described as new to science by Gunnar Degelius in 1944.

Lecanora impudens faces significant threats from air pollution and habitat degradation, which severely impact lichen communities that are highly sensitive to environmental changes. Urban development and industrial activities continue to reduce suitable substrate availability and degrade air quality in many regions where this species occurs.
