|How to prepare specimens on substrate|
Specimens on the substrate should be thoroughly dried before mailing; usually air-drying is sufficient. Large fleshy fungi may require the use of a dehydrator. Characteristics that will disappear upon drying, such as the color of fleshy fungi, should be noted and included with the specimens.
|Fungi on leaves or other thin substrates should be pressed in a plant press or simply under a heavy weight.|
Fungi on woody substrates or twigs should be trimmed to about 12 x 10 cm, dried, and placed in a paper bag or similar container.
|Herbarium packets can be used to contain specimens on twigs, bark or leaves. Packets can be made from simple materials such as a sheet of white paper with or without cotton wadding to preserve delicate structures.|
|100% cotton, acid-free paper is best for making herbarium packets for long term storage.|
