The Minnesota Mycological Society is governed by a board that is entirely staffed by volunteers. Some members are elected officers, while others serve as Committee Chairs, appointed by the President and approved by the rest of the Board. All MMS activities begin in a committee, and it takes member volunteers to make them happen. If you are interested in learning more, contact us.
