Our research group germinated in January 2005 and now includes high school interns, undergraduates, graduate students, technical support staff, and visiting researchers from around the world. If you'd like to learn more about volunteer positions, independent study opportunities, or graduate assistantships in our group (and/or in the Mycological Herbarium), please contact Betsy Arnold.
