Caloplaca atroflava (Turner) Mong.

A lichen with small orange fruiting bodies and grey thallus, resembling members of the genus Rufoplaca. From the Czech Republic, only one historical report, from diabase rocks in Český kras (Svoboda et al. 2014), and several recent unpublished records, e.g. from Hadce u Želivky National Nature Monument, are known. Recently, it was found abundant on stones near the Berounka River, in the vicinity of the locality Týřovické skály. The species is expected to occur on more localities in the Czech Republic. Suitable habitats are sunny, base-rich siliceous rocks, often on the banks of rivers. It grows in communities with C. chlorina, Porocyphus coccodes and Staurothele spp.
