Solorina crocea is unmistakable thanks to the conspicuously orange lower side of the thallus. This arctic-alpine macrolichen occurs on exposed acidic soil above the upper treeline in central Europe. Typically, it is found in snow patches. In the Czech Republic, it is considered extinct. There are two records from the 19th century; one from Sněžka Mt in the Krkonoše Mts (Körber 1855) and the other from Studénková hole Mt (i.e. Červená hora Mt) in the Hrubý Jeseník Mts (Suza 1933). A third record from Horská Kvilda in the Šumava Mts, by an unknown collector and undated, was found in the PRC herbarium.
