The lichen diversity of the proposed protected area Pukhtolova Gora counts 252 species, including 232 lichenized, 12 lichenicolous, and 8 non-lichenized saprobic fungi. Micarea laeta, M. pusilla, and Pyrenidium actinellum s. lat. are new to North-Western European Russia; Parmelia serrana, Rhizocarpon cinereovirens, and Stereocaulon taeniarum are new to St. Petersburg. Altogether 13 species recorded in the study area are red-listed in St. Petersburg, with two of them known only from historical collections. Pukhtolova Gora is an area with a high conservation value; the lichen biota of this area is one of the richest within the city limits due to the well-preserved forest habitats.
