Abstract— <p>Lichenological studies in the Serebrynoborsky experimental forestry of the Institute of Forest Science, Russian Academy of Sciences, located in Moscow and Moscow oblast, were conducted from 2010 to 2023 using the route method. Collection and laboratory processing of materials were carried out using generally accepted lichenological methods. The list of lichen species of the Serebryanoborsky forestry includes 115 species of lichens and closely related fungi, 15 of which are known only from literature data. Fifty-nine species of lichens are identified in the urban part and 98 species in the suburban part. Ecological and substrate analysis of lichens show a significant predominance of groups associated with the tree trunk substrate. The lichen cover of birch and linden has the greatest species richness. The highest diversity is noted in the most predominant forest type in the area: pine forests (including pine forests with small-leaved species), and a smaller number of lichen species are found in mixed and broad-leaved forests. The surveyed territory contains locations of four protected lichen species listed in the Red Books of Moscow and Moscow oblast, as well as ten indicator species of biologically valuable zonal forest landscapes.</p>
