Pryor Laboratory - Focusing on Lettuce Diseases, Mycology, and Alternaria at The University of Arizona School of Plant Sciences, Tucson, Arizona USA Alternaria species are perhaps the most common fungi encountered by mycologists. Estimates of the number of species range from approximately 100 to several hundred.
