A lichen inventory of the Zvoníčkovna Nature Reserve in the southern part of the Rokycany region (Western Bohemia, Czech Republic) is presented. The reserve includes a meadow enclave surrounded by a mixed forest on the site of a deserted medieval vil- lage with several springs. The forest part of the reserve is represented mainly by a well- preserved oak-hornbeam forest with many old oaks. A total of 116 lichens and 8 non- lichenized fungi were recorded. A major part was represented by epiphytic species (103 species), mainly those growing on oaks and hornbeams. Relatively high number of en- dangered species was found especially on old oaks. The most interesting of them were Arthonia thoriana, Caloplaca lucifuga, Chaenotheca phaeocephala, Inoderma byssace- um, Lecanographa amylacea, Varicellaria hemisphaerica and above all Loxospora cris- tinae, which represents a new species for the Czech Republic. Due to the large amount of lying wood, the community of lignicolous species was also relatively rich (30 species). biodiversity, deserted medieval village, epiphytes, Loxospora cristinae
