Overview

Peltigera degenii is a species of foliose lichen in the family Peltigeraceae. It was first formally described in 1927 by Hungarian lichenologist Vilmos Kőfaragó-Gyelnik. The Chinese species Peltigera neodegenii is similar in appearance. Peltigera degenii has a shiny upper surface. In North America, it is a relatively rare forest species.

Frog Pelt Lichen (Peltigera degenii) is critically endangered primarily due to habitat loss and degradation of its specialized forest ecosystems. Air pollution, particularly nitrogen deposition and acid rain, severely impacts this pollution-sensitive species. Climate change further threatens the cool, humid conditions this lichen requires for survival.
