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. Aspicilia crespiana is new to the Alps and to Switzerland. Candelariella blastidiata, C. faginea and C. oleaginescens are new to Switzerland. New observations for Candelariella plumbea s.l. and C. viae-lacteae in Switzerland are given. A key in French and in English for the species of Candelaria and Candelariella occurring in Switzerland is proposed.
