New Digital Resources: Lichen Flora of the Greater Sonoran Desert Region
Lichen Flora of the Greater Sonoran Desert Region
The third and final volume of a complete Lichen Flora for the Greater Sonoran Desert Region, covering the southwestern United States and northwestern Mexico, is now available in the Science Library, QK587.9 S66 2002.
A contingent of lichenologists contributed to production of this notable publication. Altogether, 1971 species are treated in the three volumes, of which over 25% have been described as new to science since 1990. Kerry Knudsen, Lichen Curator in the UCR Herbarium, authored 11 treatments and described ten species.
Volume I of the Lichen Flora of the Greater Sonoran Desert Region includes lichen terminology, keys to most groups, and descriptions for almost 600 species—the pyrenolichens and most of the squamulose species and macrolichens.
Volume II extends coverage to over 700 lichen species in 111 genera, the remaining genera of macrolichens, and the lichenicolous fungi (species occurring on lichens.) Included are 64 full color photographs.
Volume III completes the treatment of all remaining genera currently known from the Sonoran Region. It includes 224 color photos and covers 39 additional lichen genera, several large and less known groups such as Acarospora, Buellia, Caloplaca and Usnea.
