Cladonia stellaris
Species of lichen in the family Cladoniaceae
Cladonia stellaris or the star-tipped cup lichen is an ecologically important species of cup lichen that forms continuous mats over large areas of the ground in boreal and arctic regions around the circumpolar north. The species is a preferred food source of reindeer and caribou during the winter months, and it has an important role in regulating nutrient cycling and soil microbiological communities. Like many other lichens, Cladonia stellaris is used by humans directly for its chemical properties, as many of the secondary metabolites are antimicrobial, but it also has the unique distinction of being harvested and sold as 'fake trees' for model train displays. It is also used as a sound absorber in interior design. The fungal portion of Cladonia stellaris, known as a mycobiont, protects the lichen from lichenivores, superfluous solar radiation, and other kinds of stressors in their ecosystem.
