storsporet rurlav

Thelotrema macrosporum

Unknown

Overview

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

Thelotrema macrosporum faces severe decline due to deforestation and habitat fragmentation in its limited range. Air pollution and acid rain pose additional threats to this epiphytic lichen, which requires specific bark chemistry and humidity conditions. Climate change is altering precipitation patterns and temperature regimes in its montane forest habitats, further reducing suitable microhabitats.

Threat summary

Habitat

This epiphytic lichen grows exclusively on the bark of mature trees in humid montane forests, typically at elevations between 800-1500 meters. It requires stable microclimatic conditions with high humidity and specific bark pH levels found on old-growth deciduous and mixed forest trees.
