The article presents the results of lichenological research conducted in 2006–2020 in Piska Forest – one of some the largest forest complexes in the northern Poland. The aim of the study was to prepare a list of lichens in several interesting places in this forest, including regenerating areas destroyed by a hurricane 20 years ago. A total of 97 lichen species were found in the studied area, including such interesting and rare species as Acolium inquinans, Calicium parvum, Carbonicola anthracophila, and Lobaria pulmonaria.
