A checklist of lichens and lichenicolous fungi reported from the German part of the Bohemian Forest Range (the Bavarian Forest) is presented together with the literature sources. The area covered by the checklist is region 37 circumscribed by Grummann (1963). The list comprises 867 species currently accepted as occurring within the area. A further 44 species have been reported from the area, but their occurrence is regarded as doubtful. Seventy-seven mostly infraspecific taxa from 19th century literature sources could not be assigned to any currently accepted name and are listed separately. An overlooked, historical record of Pyxine sorediata (Ach.) Mont. is reported as the first and only German record of this species. A linear increase in the number of reported species, with no sign of saturation in recent years, indicates that the lichen flora of the region is still incompletely known. The biogeographic composition of the lichen flora broadly reflects the climatic conditions within the study area. A significantly higher proportion of northern elements among terricolous lichens could indicate a high proportion of glacial relict species within this group. Because of the incomplete floristic inventory and limited distributional data for lichens in general, these conclusions should be viewed with caution.
