Dr. Betsy Arnold, curator of the Gilbertson Herbarium gave us the following guidelines for collecting for the herbarium: 1) Collect carefully by digging up the entire mushroom(s), in a few stages of maturity if possible, multiple specimens if possible, bag the specimen(s) separately from other mushrooms in a labeled paper or wax paper bag, keep cool and dry; 2) Preserve properly by cutting a least one mushroom in half longitudinally, dehydrating at 110 degrees or less until brittle, keeping specimens free of moisture after drying; and 3) Photograph mushrooms and record important data at the time of collection such as date collected,locality, elevation, growing on ground or wood, types of trees within 20 meters, distinctive odors, bruising etc. Submit specimens to the herbarium with a voucher that provides the following information: Scientific name, Family, Collector, Determiner, Date Collected, Locality (eg. USA, Arizona, Coconino Nat. Forest, SR 180), Habitat, Notes.
