A Spore Print is simply capturing a mushroom's spores drop on onto a surface.
Spore prints are a necessary step in a 100% accurate ID of a mushroom.
Interested in learning the simple process?
1. Clip the stem or stipe of your gilled mushroom so that only a small bit remains.
2. Place the mushroom cap, pore surface down, on a piece of paper (white if you're expecting a dark print, or if you’re expecting a light colored spore print, then be sure to use a darker background! *a sheet of tin foil is a great option*).
3. Place a cup or bowl over the mushroom cap on the paper or foil and place a small object (like a pencil, pen, clothes pin etc.) just under the lip so that there’s a small opening for airflow.
*this creates humidity, or moist air, which mushrooms love. Plus it puts them in the mood to drop their spores 😏*
Now all you have to do is wait!
Its usually best to wait about 6 hours (or overnight), then remove the cup and take a look at what spores have dropped!
If you don’t see any there’s a chance you’ve plucked a mushroom that’s too mature. It’s best to try a few spore prints at a time of the same species just to be sure you’ll have a successful print.
