Bilovitz, P. O. 2014. The importance of old deciduous trees and wooden fences for lichen diversity — an example from the Teichalm area (Eastern Alps). — Herzogia 27: 199 –204.
The investigation of the epiphytic lichen diversity on four neighbouring old, isolated deciduous trees and a wooden fence in the Teichalm area yielded 74 lichen taxa and 4 lichenicolous fungi. Anaptychia ciliaris, Cyphelium notarisii, Ramalina fastigiata and R. fraxinea are remarkable records. The usually sterile lichen Thelomma ocellatum was rich in fertile thalli. The known lichen diversity of the Teichalm-Sommeralm region increases from 87 to 122 taxa.
