This contribution presents records of 84 epiphytic, terricolous, lignicolous, and epilithic lichen species from fifteen localities in the eastern part of the Veľká Fatra Mts and the western tip of the Nízke Tatry Mts in Central Slovakia. In addition, we report the occurrence of the lichenicolous fungus Illosporiopsis christiansenii. Of the recorded lichen species, three are legally protected (Gyalecta herculina, Lobaria pulmonaria, and Nephroma resupinatum), and nine, including the aforementioned legally protected species, are critically endangered (CR), five are endangered (EN), twelve are vulnerable (VU), and three species fall into the category of LR:nt. Other notable macrolichens include Anaptychia ciliaris, Parmelia submontana, and Ramalina fraxinea. From crustose microlichens, the rare and critically endangered species Gyalecta fagicola and Gyalecta herculina were recorded (additional recent finding from Malá Fatra Mts is added in Discussion). Another noteworthy find is Caloplaca turkuensis, recently recorded outside its previously known Slovak locality, with a corrected identification following an earlier misattribution as C. monacensis. The presence of deadwood, particularly in natural or near-natural forests, was shown to be a key substrate for lignicolous species, including Xylographa paralella and X. vitilligo, which are indicators of ecologically stable forests with continuous deadwood availability. Furthermore, the fruticose lichen Usnea barbata, once considered extinct in Slovakia, was recorded in several locations and now appears to be relatively common, suggesting a reconsideration of its conservation status. This study results from a collaboration among researchers, nature conservation professionals, and citizen scientists. Key words: citizen science, diversity, iNaturalist, the Western Carpathians.
