Scytinium tetrasporum

Unknown

Overview

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

Scytinium tetrasporum faces severe threats from air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its substrate and disrupt its symbiotic relationships. Habitat loss due to urbanization and industrial development has eliminated many suitable sites, while climate change is altering moisture regimes critical for this lichen's survival.

Threat summary

Habitat

This lichen species typically grows on calcareous rocks, limestone outcrops, and occasionally on mortar of old walls in areas with specific humidity and air quality requirements. It is found in temperate regions where it requires clean air conditions and stable moisture levels for its photosynthetic partner to function effectively.
