Caloplaca cirrochroa (Ach.) Th. Fr.

An inconspicuous lichen with bright yellow soralia on an orange lobate thallus. Currently, it belongs in the genus Leproplaca (Arup et al. 2013), which contains mainly vegetatively reproducing species. It occurs on limestones or calcareous insertions in siliceous rocks, especially on overhangs and vertical walls. In the Czech Republic, it can be found in nearly all areas with limestone rocks, or on calcareous silicates in river valleys. It occurs from lowlands to mountain foothills. Furthermore, it has been reported also from mountains, from Velká Kotlina in the Jeseníky Mountains, but this record is probably incorrect (Vondrák & Malíček 2015).
