Lišejníky zaznamenané během bryologicko-lichenologických dnů na Broumovsku

We present a list of 120 lichen taxa and one lichen-allied fungus recorded in the Broumovsko Protected Landscape Area in September 2018 during the 30th Autumn Days of the Bryological and Lichenological Section of the Czech Botanical Society. We explored mainly acidic and calcareous sandstone rocks in this lichenologically poorly known area. Acidic sandstones harboured, for example, Arthonia arthonioides, Micarea leprosula and Mycoblastus alpinus whereas those of the calcareous rock types harboured Verrucariahochstetteri.Ahalf-dayexcursionledto a settling pit with early succession stages occupied by a few rare terricolous/bryophilous species such as Bacidia pycnidiata, Placidiopsis oreades (only one locality in the Czech Republic), Thelocarpon impressellum (the second locality in the Czech Republic), Verrucaria bryoctona and Vezdaea leprosa. The region is quite poor in epiphytic lichens, but several currently spreading species have been recorded, for example Flavoparmelia caperata.
