Callome multipartita (Sm.) Otálora, P.M. Jørg. & Wedin

Usually a fertile, saxicolous lichen with relatively narrow, branched, often brownish lobes. It is a characteristic species of natural calcareous rocks, where it grows mainly in humid microhabitats, e.g. seepage rocks. Although C. multipartita occurs in various parts of Europe, it is usually rare there. In the Czech Republic, the species was recorded a few times in the first half of the 20th century, in Srbsko in the Český kras, in Kotouč near Štramberk, in Čebínka near Tišnov and in the Pálava Hills (Degelius 1954, Pišút 1968). Recently, it was found on Ca-rich andesite rock at the locality Týřov in the Křivoklát region.
