Fellhaneropsis vezdae

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Fellhaneropsis vezdae faces severe threats from air pollution and acid rain, which directly damage its sensitive thallus structure and disrupt the delicate chemical balance required for photosynthesis. Urban development and forest fragmentation have eliminated many of its traditional host trees, while climate change is altering the humid microclimatic conditions this lichen requires for survival. The species' extremely slow growth rate means that once populations are lost, recovery can take decades even under optimal conditions.

Threat summary

Habitat

This crustose lichen grows exclusively on the bark of old deciduous trees, particularly favoring mature oak and beech in humid, sheltered forest environments. It requires stable microclimatic conditions with high humidity and minimal air pollution, typically found in undisturbed woodland areas with continuous canopy cover.
