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.

You want the spores to fall directly down onto the paper from the mushroom cap. To do this, cover the cap with a glass or small bowl which will prevent air currents from carrying away your spores. After 6-12 hours, remove the cap. You should have a fully formed mushroom spore print.

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).

Cultivating spores

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.

Printer paper. Black or white will usually work some mushrooms have very light or dark spores so you may want to try on both. A glass bowl or cup large enough to cover the mushroom.

Put on gloves to keep things sterile. Fill bag with a scoop of spent coffee grounds, a bigger scoop of shredded paper, and a small scoop of spawn and seal bag with tape. Shake bag until fully incorporated. Let your spores sprout!

Be sure to choose mature mushrooms that are not dried out. If you think your mushroom is too dry, try adding a single drop of water to the cap to help release the spores. Creating a mushroom spore print is truly an artform—what species and methods work best for you?

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.

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.

Colonization occurs after inoculation. This is when the mycelium will start to take over the grain that was inoculated with spores. This period usually lasts between 3 to 6 weeks depending on strain and environmental conditions. Ideal conditions for this phase are in a dark place and temperature between 72 F – 80 F.

What color should spore prints be? ›

Spore prints are usually white to cream, black, or shades of red, purple, or brown. The poisonous false parasol (Chlorophyllum molybdites) has a green spore deposit.

When two spores of the same species land close together in a favorable environment, they combine and make mycelium. This is a form of sexual reproduction, as each spore only contains half of the genetic material (similar to gametes) required to make a viable offspring.

A spore print makes spores on fungi appear, it is useful for identification and study. Sometimes mushrooms can look exactly identical from the outside, but after doing a spore print, they can actually be a completely different species! If the color is useful for identifying a species.

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.

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.

Start by choosing a fresh, healthy mushroom and carefully remove the stem to expose the gills. Place the cap on paper or glass and cover it with a bowl to protect from air currents for 24 hours. After revealing your spore print, scrape spores into a sterile container for storage.

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.

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.
