Abstract
Lichens on six boulder screes in the southern part of the Brdy Hills (Central Bohemia) were studied during 2014. The screes are rich in Cladonia species but poor in arctic-alpine (e.g.
Brodoa intestiniformis) lichens due to the low altitude. A list of 200 lichen taxa is presented.
Twenty-five species are new for the Brdy Hills. Bacidia circumspecta, Bellemerea sanguinea, Biatora fallax, Cetraria sepincola, Cladonia asahinae, C. macroceras, C. stellaris, C. straminea, Fuscidea pusilla, Hertelidea botryosa, Icmadophila ericetorum, Lecidea leprarioides, Mycoblastus sanguinarius, Porpidia cinereoatra, Rhizocarpon cinereovirens and R. oederi represent the most interesting records.
The Fajmanovy skály a Klenky Nature Reserve, with several well preserved screes and a relic pine forest, is the most valuable and species-rich locality (147 lichens recorded). In comparison with historical records, most of the terricolous and saxicolous lichens previously reported still occur at the localities under study
