This paper is a continuation of the new series started in 2020 to publish the new or interesting lichenological discoveries made in Switzerland or in the Geneva canton. Lobaria pulmonaria, a macrolichen endangered in a large part of its distribution area in Europe and particularly on the Swiss plain, was rediscovered in the canton of Geneva. Rhizoplaca subdiscrepans a distinct species from R. chrysoleuca was found to occur in three localities in Switzerland.
