Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Buellia asterella faces severe threats from air pollution and acid rain, which directly damage its thallus and disrupt the delicate chemical balance required for photosynthesis. Urban development and industrial activities have eliminated much of its suitable substrate, while climate change alters the specific humidity and temperature conditions this lichen requires for survival.
Habitat
This crustose lichen grows on calcareous rocks and concrete surfaces in urban and semi-urban environments. It requires specific pH conditions and moderate air quality, typically found on walls, monuments, and limestone outcrops in areas with reduced industrial pollution.
