Caloplaca nivalis (Körb.) Th. Fr.

Lichenogr. Scand., 1: 191, 1871. Basionym: Zeora nivalis Körb. - Denkschr. schles. Ber. vaterl. Kultur: 321, 1853.
Synonyms: Bacidia livida (Bagl. & Carestia) Lettau; Bilimbia livida Bagl. & Carestia; Candelariella nivalis (Körb.) Lettau; Gyalolechia nivalis (Körb.) A. Massal.; Lendemeriella nivalis (Körb.) S. Y. Kondr.; Placodium nivale (Körb.) Tuck.
Distribution: N - TAA, Lomb, Piem (Isocrono & al. 2004), VA (Piervittori & Isocrono 1999).
Note: a cool-temperate to arctic-alpine, circumpolar species found on silicicolous mosses (especially Andreaea and Grimmia). The statement of Printzen (1995) that the type of Biatora livida is Fulgensia schistidii is wrong: the type material of the former species, analyzed by M. Tretiach (pers. comm.), clearly belongs to Caloplaca nivalis.
