Caloplaca crenularia (With.) J. R. Laundon

A conspicuous crustose lichen with rusty-red fruiting bodies and a grey thallus, nowadays included in the genus Blastenia. It occurs on base-enriched siliceous rocks. Its centre of distribution is in the Mediterranean and coastal Western Europe (Vondrák et al. 2019). In the Czech Republic, it is very rare and its occurrence is limited to diabase outcrops near Prague and in Český kras (the Bohemian Karst) (Svoboda et al. 2014).
