Members of our research group

    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.

    This is our group as of fall 2013.
