Hello Foraging Friends,
Did you know it’s easy to make prints? Although is only one part of mushroom identification, shape, color, gill or the lack of and more should be throughly exhausted first, through field guides or a mushroom forager with experience.
That said, After acquiring a few mushrooms, preferably, whole, mature ones. At home, you will want to gather a few items, black or white paper, even aluminum foil. The mushroom has to sit flush on the paper, to release its spores within 2-24 hours. Be prepared for this amount of time to see results.
Each mushroom has its own spore pattern and color, according to their species. Which deepen your learning, as you document each mushroom, it will be easy to keep track of in a journal too.
A few color identifying Examples:
White - oysters and toxic amanita species(destroying angel)
Brown/cinnnamon, to chocolate brown - common edible mushrooms from the Agaricus genus , button or portabella.
Black or Purple-black Coprinus species such as inky caps
Spore printing may take some of the guessing out of identifying your mushroom, especially when you have a look a like. You’ll also learn more about mushrooms and create some unique impressions. A natural stamp of mushroom prints.
Below is a brief step by step of the supplies and process.
Supplies
- Mature or gilled mushroom of your choice
- Paper or foil if you don't know the color using half black or white or just black paper so that you can see the print
- A container, a glass bowl or paper cup to cover the mushrooms
- Knife or scissors
Prepare the mushroom
- Remove the stems with your knife or scissors so that the Gills will be close as possible to the paper.
- Optional add moisture if the mushroom is dry, you can add a tiny drop of water on top of the cap to help it releases for us or just use a damp paper towel on top of the cap.
Printing set up
- Place the mushroom cap/pour side down on the surface paper/foil
- Cover the cap with a bowl or glass to prevent the air from scattering your pores, and to maintain the humidity
- Wait, let the mushroom sit 2 to 24 hours and the time depends on the freshness and humidity.
The Big Reveal
- Carefully remove the cover
- Gently lift the mushroom caps straight up to avoid smudging the print
- Examine the color which is critical for identification
*For identification, take a picture of the print alongside the mushroom and keep in a Foraging Journal.
*For cultivation use aluminum as it is sterile and easy to fold and store spores
*To preserve spray the dry print with an artist fixative or hairspray from 2 to 15 inches away.
*Finally for difficult specimens like polypus, you may need to wrap them in a wet paper towel overnight to encourage for release.
A Google search of “how to take a mushroom sport print” will bring up this and more information and resources for making your own sport print. It’s easy once you find a mushroom.
