Buellia sandstedei (Zwackh) Sandst.

This species does not contain any secondary metabolites detectable by TLC. Morphologically, it is somewhere in between*Amandinea punctata* and Buellia badia. Its thallus is relatively inconspicuous, grey to brown, and sometimes forms marginal lobes. According to DNA sequences, B. sandstedei * is close but clearly separated from *B. badia.

The lichen grows on sunny, mostly basic siliceous rocks and stones. It is apparently more frequent in xerothermic localities. Its overall distribution is unknown, probably for its rarity and possibly also overlooking. In the Czech Republic, the species was first found in 2020. So far it has been reported from the Křivoklát region, Vltava River valley and České středohoří Hills.
