Species Profile
Caloplaca alstrupii is a species of corticolous (bark-dwelling) crustose lichen in the family Teloschistaceae. Found in Denmark, it was described as a new species in 1999 by the lichenologist Ulrik Søchting. It is a member of a group of soredia-producing Caloplaca species that do not produce anthraquinone pigments; lacking these typically colourful pigments, the thallus of lichens in this group is often inconspicuous.
Caloplaca alstrupii is critically endangered due to its extremely limited distribution and vulnerability to habitat degradation. This rare lichen species faces threats from air pollution, climate change, and human disturbance to its specialized coastal rock habitats.
