Lišejníky vrchu Sedlo v Českém středohoří (severní Čechy)

This contribution presents the results of a lichenofloristic survey of the Sedlo Hill near the town of Úštěk in North Bohemia, which was undertaken in 2011–2013. The tephrite hill is covered mostly by a scree forest. In total, 72 lichen species were recorded, including one endangered lichen (Usnea subfloridana) and three vulnerable species (Bryoria fuscescens, Melanelixia subaurifera and Physcia stellaris). Aspicilia cinerea, Lecanora cenisia, L. soralifera, Miriquidica leucophaea, Porpidia rugosa and Rimularia insularis represent remarkable species from tephrite rocks.
