However, unless you are 100% sure that the mushrooms you used are edible, I recommend against allowing your children to touch, and if they do touch, be sure they wash their hands immediately afterwards. My daughter was keen to touch the spores to see how they felt. The mushroom produces no spores in that part. The holes in the middle of each print was from where the stems were removed. It dumped the most spores of the three mushrooms and there are no signs of gill lines anymore. The print on the bottom left was clearly made by a mature mushroom. When ready, gently remove the mushroom caps from your paper.Īs you can see in the image below, it is possible to see lines of spores from the gills of the mushroom cap in the print at the top and the print on the bottom right. In general, you should not need more than one day to see spore prints. But if your mushroom is very mature you may see a spore print in as little as an hour. You can order a pre-made spore syringe online. Storing spores in the refrigerator have been know to last for 18 years. When doing the first syringe it’s a good idea to fill it once or twice and then empty it again into the jar. Then you take a small portion of your spore print, mix it with some distilled water (same as sterile water) and suck into a syringe to make a spore syringe to use to inject into your substrate with a needle for the syringe. The spore syringes can be made immediately. Scrape with the scalpel some spores from the print so they fall into the water. We waited 24 hours before checking our spore prints. Remove the tinfoil from the flask with water and use the tweezers to take the spore print (partially) out of the bag. If you aren’t sure what color spores your mushroom produces, you may want to place at least one mushroom on a white sheet paper and at least one mushroom on a black sheet of paper until you determine what the spore color is. If you know that your mushroom produces dark colored spores, then place it gills-down onto a white sheet of paper. If you know that your mushroom produces light colored spores, then place it gills-down onto a black sheet of paper. Do take care though: some species are poisonous. Most spores are some shade of white, pink, brown or black (although there are unusual varieties that have colors such as yellow, orange, and green). Autumn is the time for fungi forays, so here’s a simple way to create a spore print. Mushroom spores come in a variety of colors. Now you have to decide whether to use white paper or black paper. To begin, remove the stems from your mushrooms, leaving only the mushroom caps. To make mushroom spore prints you will need the following materials: Certain mushrooms species can cause death if ingested. Use caution when using mushrooms around young children who put things in their mouths.
First a word of caution: Never eat mushrooms unless you are 100% sure they are safe to eat because, for example, you purchased them from a reliable vendor.
