The Arizona State University Lichen Herbarium currently houses over 109,000 fully accessioned and
databased lichen specimens from all over the world. A significant fraction of these specimens
are being revised in the context of the
Greater Sonoran Desert Flora Project funded by the
National Science Foundation.
Due to lack of personnel, the ASU Lichen Herbarium will be closed during each summer (May 15 through Aug. 15).
The third and final volume of the Greater Sonoran Desert Lichen Flora has been published!!
