Urbanavichus, G. & Urbanavichene, I. 2014. An inventory of the lichen flora of Lagonaki Highland (NW Caucasus, Russia). — Herzogia 27: 285–319.

The lichen flora of the Lagonaki Highland (NW Caucasus) was examined. A list of 677 species, including 610 lichenized fungi, 60 lichenicolous fungi and 7 non-lichenized saprophytic fungi, is presented based on the authors' original observations. Locality and substrate data are additionally given. 491 species are recorded from the Lagonaki Highland for the first time. 125 species are new records for the Russian Caucasus, including 112 not previously recorded from the Greater Caucasus. Thirty-six species are reported from Russia for the first time: Alyxoria variaeformis, Anema tumidulum, Arthonia calcicola, Arthothelium orbilliferum, Bacidia coprodes, Biatora veteranorum, Calicium victorianum, Caloplaca rouxii, C. schoeferi, Candelariella oleaginescens, Didymellopsis pulposi, Endococcus pseudocarpus, Farnoldia muscigena, Fulgensia fulgida, Gyalecta thelotremella, Lecania coeruleorubella, Lecanora reuteri, Lichenochora wasseri, Lobothallia cheresina, Marchandiobasidium aurantiacum, Niesslia peltigericola, Opegrapha rotunda, Physcia erumpens, Placidiopsis tiroliensis, Placynthium posterulum, Polysporina cyclocarpa, Rinodina furfuracea, R. luridata, Scoliciosporum schadeanum, Stigmidium eucline, S. lecidellae, Verrucaria mortarii, V. ochrostoma, Verrucula elegantaria, Vezdaea stipitata. The ecology of some interesting species and the conservation status of the lichen flora in the study region are discussed. The flora contains some interesting indicators of long ecological continuity of the forests.
