Thelopsis rubella
Local name: röd pysslinglav
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Röd pysslinglav faces severe decline due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its bark substrates. The species is highly sensitive to atmospheric changes, with populations disappearing from areas experiencing increased industrial emissions and urban air quality degradation. Climate change compounds these pressures by altering humidity patterns essential for this moisture-dependent lichen's survival.
Habitat
Röd pysslinglav grows exclusively on the bark of old deciduous trees, particularly favoring smooth-barked species in humid, sheltered forest environments. The species requires stable microclimatic conditions with consistent moisture levels and minimal air pollution exposure.
