Pertusaria flavocorallina
Overview
Pertusaria flavocorallina is a crustose lichen species characterized by its distinctive yellowish to coral-colored thallus that forms thick, warty crusts on substrate surfaces. This lichen plays an important ecological role as a primary colonizer and contributes to soil formation and nutrient cycling in its ecosystem. Like other lichens, it represents a symbiotic relationship between fungal and algal components.
Pertusaria flavocorallina, a critically endangered lichen species, faces severe decline primarily due to habitat loss and degradation of its specialized coastal and maritime environments. Air pollution, particularly from sulfur dioxide and nitrogen compounds, significantly impacts this sensitive lichen species. Climate change and coastal development further threaten the remaining populations of this rare species.
Habitat
Pertusaria flavocorallina typically grows on bark of deciduous trees and occasionally on rock surfaces in old-growth forests and mature woodland environments. The species requires stable microclimatic conditions with specific humidity levels and minimal air pollution to thrive.
