About Lichen Flora of the Greater Sonoran Desert Region
The principal objective of the project is to produce a comprehensive lichen flora for the Sonoran Desert and adjacent regions. The study will include all lichenized fungi (currently over 250 known genera) as well as a limited number of saprophytic fungi (currently 7 known genera) that are frequently treated with lichens (e.g. Mycocalicium, Sarea, etc.). In addition, we also plan to include lichenicolous fungi (currently 30 known genera).
