Lichen inventory of the canton of Geneva, Switzerland — large biodiversity for a small canton. — Herzogia 28: 153–184.;;This paper presents a lichen inventory of the Canton of Geneva, Switzerland, based on field, herbarium and literature data. A total of 614 taxa occurred in the studied area, which represents an increase of 253 taxa (+70%) recorded for the canton. The main reason for such a huge increase in the number of taxa is that the present inventory is the first comprehensive floristic study conducted in the canton since 1862. Out of the 614 identified taxa, 18 species are recorded for the first time in Switzerland. A further 66 species mentioned for the area from the literature or herbarium specimens have been... excluded. The species list includes information on the years of the oldest and the most recent collection and the respective collectors.
