Lišejníky vrchu Lovoše v Českém středohoří

127 taxa of lichen-forming fungi were found on Lovoš hill in the České Středohoří Mts (Northern Bohemia, Czech Republic) during the short cryptogamological excursion in 2004 and lichenological survey conducted by the first author during 2011–2013. The hill is covered by xerothermic grassland vegetation, developed on basalt and trachytic rocks, and a deciduous forest with specific lichen flora (including rare species such as Caloplaca grimmiae, Lecanora argopholis, Dimelaena oreina and Xanthoparmelia tinctina). Epiphytic flora of the Lovoš Mt. has been completely damaged by air pollution because of acidic emissions in the past, but recently the area is slowly recolonized by some acidophilous or nitrophilous lichens. A concise history of lichenological research in the area is included as well.
