This is really easy, just wash your hands well, then take a fresh shroom and gently twist the cap off away from the stem ( Or, use a sterilized knife blade to cut the stem off as close to the cap as I can without touching it too much). Then place the cap, gills down, on a sterile card or piece of foil. Cover the cap and card with a clean, small container to keep drafts from blowing the spores away, and to prevent dust/contaminants from settling on the card/glass/Foil. I usually use a small juice glass for this purpose. Leave the covered 'shroom cap on the card/Foil overnight. I suggest folding the card/foil the next day and keeping it in a small ziplock bag or just fold it up in paper and tape it close good.. If kept at room temp, the spore prints can last for a very long time. |
