Caloplaca aurantia (Pers.) Hellb.

A conspicuous yellow crustose lichen with a lobate thallus, nowadays included in the genus Variospora. In the Czech Republic, it is linked to sunlit limestones and occurs only in the southern Moravia. Besides the Pálava Hills, where it is abundant, it has been reported from Podyjí (Hardegg), from Stránská skála near Brno and historically also from Čebínka near Tišnov (Šoun & Vondrák 2008). Sometimes it is confused with C. flavescens, a visually and ecologically similar species.
