Epiphytic Lichens of Stužica (E Slovakia) in the Context of Central European Old-Growth Forests
Abstract: Vondrak, J., Malicek, J., Soun, J. & Pouska, V. 2015. Epiphytic lichens of Stužica (E Slovakia) in the context of Central European old-growth forests. — Herzogia 28: 104–126. Based on recent lichen inventories, we report 230 epiphytic and epixylic species in the Slovakian old-growth beech-dominated Stužica forest. Microlichens represent 75% of species. By comparison, lichen lists of only three other Central European forests exceed 200 species, and none of them reached 230. Lichen diversity is very unequally distributed in Stužica; the extensive south-facing slopes are poor in species, whereas damp brook valleys and upper parts of slopes above 1000 m alt. are rich. Some rare macrolichens were collected in Stužica about 50 years ago but could not be relocated during the present survey. Twelve species are new to Slovakia: Epigloea urosperma, Graphis macrocarpa, Kirschsteiniothelia recessa, Lecidea sanguineoatra, Lepraria ecorticata, Micarea nigella, Opegrapha trochodes, Parmotrema arnoldii, Pertusa...
