Overview

Peltigera horizontalis is a species of lichen in the family Peltigeraceae. It was first described by British botanist William Hudson in 1762 as Lichen horizontalis. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus Peltigera in 1790.

Horizontal Pelt Lichen faces severe decline due to habitat loss from deforestation and land conversion, air pollution that disrupts its sensitive physiological processes, and climate change altering moisture and temperature regimes essential for its survival. As a slow-growing epiphytic species, it is particularly vulnerable to rapid environmental changes and has limited ability to recolonize disturbed areas.
