Rinodina bischoffii (Hepp) A. Massal.

Rinodina bischoffii has distinctive spores with a strongly pigmented band around the central septum (Bischoffii-type). Its thallus is inconspicuous without vegetative propagules. It grows on calcareous rocks and stones, commonly on limestone, calcareous sandstones (including “opuka”), more rarely also on calcareous silicates or calcareous insertions in siliceous rocks. The species is among the early lichen colonizers, for example, in quarries. It occurs in diverse habitats, but is rare on anthropogenic substrates and absent from mountains. At lower elevations, it is distributed almost all over the Czech Republic, most abundantly in karst areas (such as the Bohemian and Moravian Karsts, Pálava Hills etc.).
