Overview
Peltigera latiloba is a species of lichen-forming fungus in the family Peltigeraceae. It is a large, leafy (foliose) lichen with broad, boat-shaped lobes and a hairy upper surface, growing on mossy ground in subalpine and low-alpine habitats. Like other members of the P.
aphthosa group, it is a trimembered lichen, housing both a green alga and a cyanobacterium as photosynthetic partners. It was described in 2005 from Norway and Alaska, and has since been recorded from Greenland, East Karelia, and Kamchatka.
Peltigera latiloba faces significant threats from habitat degradation due to air pollution, particularly nitrogen deposition and acid rain, which alter the chemical composition of its substrate. Climate change poses additional risks through altered precipitation patterns and temperature fluctuations that affect the delicate moisture balance required for this lichen's survival.
Habitat
This foliose lichen grows on soil, moss, and decaying organic matter in humid, shaded environments including old-growth forests, woodland margins, and moss-covered rocks in temperate and boreal regions. It requires stable moisture conditions and clean air quality to maintain its symbiotic relationship with cyanobacteria.
