A spore is a reproductive cell. Some plants make them but bacteria, algae, and fungi make them too. Spores are to mushrooms as seeds are to plants. Spores are how mushrooms reproduce and make more mushrooms.
The first step to making a spore print is collecting a mushroom.
Please follow the rules of where you collect and make sure it is okay to collect from the area you are visiting.
Bring something to carry your mushroom with, like a basket or paper bag. You don’t want them to get squished in your pocket! Only pick the mushroom if there are a lot around because they are important for the environment.
Do you know why mushrooms are important?
Mushrooms are decomposers which means that they break down dead materials such as fallen leaves and logs to make soil and nutrients that help other living things survive. Remember to wash your hands after handling mushrooms!
Once back home:
Gather jars or containers big enough to place over the mushrooms. Gather white and black paper. It is okay if you only have white paper, but some mushroom spores are white and therefore they won’t show up on white paper that well.
Take the stems off the mushrooms using your hands or scissors.
Place the mushrooms with the gills or pores facing down onto the paper. Then place the container over the mushroom to create an airtight seal.
Leave the mushrooms covered anywhere from a couple hours to overnight based on how fresh the mushrooms are.
After you let the mushrooms sit for a while, carefully pick up the containers and the mushrooms to reveal the spore print. Spore prints are fragile, so try to avoid touching it.

or pores facing down onto the paper. Then place the container over the mushroom to create an airtight seal. Leave the mushrooms covered anywhere from a couple hours to overnight based on how fresh the mushrooms are.
Put a drop of water on the top of the cap to help release the spores. Cover the cap with a paper cup or glass and leave for 2-24 hours, depending on the humidity and the freshness of the mushroom. The spores will fall on the paper, foil or glass, making a spore print pattern.
For white-spored mushrooms use black paper or clear plastic or glass. If you intend looking at the spores under a microscope, then whatever colour the spores are making the spore print on a microscope slide or (better still) a slide cover slip is ideal.
Cover the mushroom with a bowl (to stop it drying out and to reduce air currents that might spoil your print by blowing the tiny spores around). 3. Leave everything where it is for at least 2 hours or longer (overnight).
The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse.
The spore prints are permanent. The illustra- tion shows a spore print from Gymnopilus junonius made in 1988 which still retains its colour. The spores can be sampled but this entails a degree of destruction. spores are known to be hard to germinate, only the lightest of spore prints will be required.
Lay the cap of the mushroom with the gills upside down onto a piece of paper. For the majority of specimens, a normal sheet of white paper works fine. However, some mushrooms have white spores- so if you are taking prints for the purposes of identification, you might want to consider also getting some black paper.
Take the stems off the mushrooms using your hands or scissors. Place the mushrooms with the gills or pores facing down onto the paper. Then place the container over the mushroom to create an airtight seal. Leave the mushrooms covered anywhere from a couple hours to overnight based on how fresh the mushrooms are.
Maintaining the ideal humidity is perhaps the trickiest part of making spore prints. Dry mushrooms won't give a good spore print, but wet ones can make a sloppy mess. If you put a small mushroom on a piece of paper and cover it with a large bowl you may end up with a shrivelled cap and no spore print.
Once you have a spore print (by following the instructions above) you can then use it to cultivate and grow your mushrooms. This can be done by creating a spore syringe, where the spores are re-hydrated using sterile water and then used to inoculate the growing medium.
If working with a reusable inoculation loop, heat the inoculation loop red hot in the flame of an alcohol lamp and let it cool down in your hand. Do not touch the spore print, inoculation loop or agar medium. Now rub the spore print until the whole loop has gathered some spores.
Spores may be collected from a spore print, which is a powdery imprint left on a surface by the spores of a mushroom. Spore prints are an important field mark for identifying mushrooms, as their colors can help distinguish between species. A mushroom releasing spores.
White and black paper are commonly used for this purpose – you would make sure half of the mushroom sites over the white paper and the other half sits over the black paper. White paper works well for mushrooms with non-white spore prints, while black paper is ideal for capturing white or light-colored spores.
5. Lift the jar and remove the mushroom to reveal your mushroom spore print! Allow it to air dry for two hours before storing it in a safe dry place. You can also fram the spore prints in a frame as art.
Then, to make a spore syringe, scrape the spore print into a glass with sterilized water and pull the solution into a syringe. After you have created a spore print, you can save it for later use, make a spore syringe, apply it to an agar solution or create a liquid culture.
Remove the stem of the specimen and place the cap of the mushroom on the spore print card with the gills (or pores) facing downward. Cover it or leave it undisturbed overnight and compare the colour of the resulting print with descriptions in your field guide.
