Athallia saxifragarum is a species of terricolous (ground-dwelling) crustose lichen in the family Teloschistaceae.[2] First described by Josef Poelt in 1955 as a member of Caloplaca, it was reclassified into the genus Athallia in 2013 following molecular phylogenetics studies. This lichen is characterized by its thin white thallus and small yellowish-orange apothecia. It primarily grows on bryophytes and plant detritus, showing a particular affinity for Saxifraga species, and is typically found in calciferous or alkaline environments in Arctic and alpine regions, including Greenland, Svalbard, and the European Alps, with recent documentation in Fennoscandia. It also occurs in North America.
