Spighe Paglie: 9 (1853).
Basionym: Biatora tricolor Mont., Annls Sci. Nat., Bot., Sér. 2 18: 266 (1842).
Note: B. tricolor might be a chemical race of B. leucoxantha: "Two species were collected in the same locality. Following Hafellner (1997), one specimen with apothecia reacting only K+ purplish in section belongs to B. leucoxantha, whilst other specimens in which the hymenium and hypothecium react K+ bluish violet in addition to the K+ purplish reaction belongs to B. tricolor" (Ertz & Diederich 2008: 392).
