Effie A. Southworth Effie Almira Southworth Spalding (1860–1947), was an American botanist and mycologist, and the first woman plant pathologist hired by the United States Department of Agriculture (USDA). Her most important discovery was the 1887 identification of the fungus "Colletotrichum gossypii" as the cause of cotton cankers, a disease which killed thousands of acres of cotton and was a major economic threat. She taught botany at several institutions, worked at the Desert Botanical Laboratory with her husband, and established the Botany Department Herbarium at the University of Southern California.
