Caloplaca citrina (Hoffm.) Th. Fr.

A yellow sorediate lichen, newly included in the genus Flavoplaca. It is morphologically and ecologically very similar to the species C. flavocitrina. In the Czech Republic, its occurrence has been confirmed from Andělská Hora near Karlovy Vary (Vondrák et al. 2009) and from Velká Kotlina in the Jeseníky Mountains (Vondrák & Malíček 2015). It is expected to be more abundant, however, the safe differentiation from the common C. flavocitrina requires DNA sequencing, which complicates its occurrence mapping.
