Overview

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

Mørk uldlav (Ephebe hispidula) faces severe threats from air pollution and acid rain, which directly damage its sensitive thallus structure and disrupt its photosynthetic processes. Climate change compounds these pressures by altering precipitation patterns and increasing temperature extremes that exceed the species' narrow tolerance range. Habitat loss through deforestation and urban development further reduces available substrate for this specialized lichen.

Threat summary

Habitat

This lichen species grows on the bark of deciduous and coniferous trees in humid, old-growth forests and well-established woodlands. It requires stable microclimatic conditions with consistent moisture levels and clean air quality, typically found in undisturbed forest environments.
