Lišejníky Vrchu Bořeně (severní Čechy)

This contribution presents results of the first licheno-floristic survey of the Bořeň National Nature Reserve, a phonolite hill south of Bílina in Northern Bohemia. The lichenological fieldwork was undertaken between 2011– 2013. The reserve is characterized by xerothermic vegetation (rocks, grass- lands). Eighty — six taxa of lichen-forming fungi were identified. The rocky steppe on dry south-facing hillside is the richest biotope for lichens. The area is relatively rich for saxicolous and poor for terricolous species. The most interesting finds were epiphytic lichens Usnea subfloridana, U. scabrata and U. substerilis.
