Mushrooms are a fascinating family of fungi, with some species offering edible delights and others providing a vibrant splash of colour in nature. Growing mushrooms from spores is an intricate process that requires a specific set of steps and a great deal of knowledge and skill. The spores are microscopic in size but contain the blueprint for new mushroom growth, and a single mature mushroom can contain up to 16 billion spores, offering plenty of opportunities for propagation. The most common method for harvesting spores is by making a spore print, which involves placing the mushroom gill-side down on a sterile surface, covering it with a glass container, and allowing it to release its spores. This print can then be used to create a spore syringe, which is crucial for inoculating the growth medium. Mastering agar transfers and using a still air box can elevate your cultivation success, providing a self-sustaining system for endless mushroom growth.

What You'll Learn
Collecting spores
Firstly, select a mature mushroom. It is important to ensure that the mushroom is a known edible variety. Carefully remove the stem from the mushroom and gently remove any veil or skirt that may be present to expose the gills. If you want to keep the stem attached, cut a hole in an index card and place it over a bowl, then insert the stem into the hole so the cap rests on the paper.
Next, place the mushroom gill-side down on the paper or microscope slide. If using a slide, place a drop of water on the mushroom and cover it with a bowl. If using paper, place a glass over the mushroom. Leave this setup for 2-24 hours.
Finally, if using a microscope slide, scrape off some of the spores from your spore print with a needle or scalpel and place them on the slide with a drop of water. Cover with a slip, and your spores are ready for observation or preservation. If using paper, you can preserve your spore print by spraying it lightly with an artist spray or hair spray.

Making a spore print
Prepare the Mushroom:
Cut off the stem of the mushroom near the base of the cap to expose the gills or tubes, depending on the type of mushroom. Make sure the cap is dry as moisture can affect the quality of the print. If you are collecting mushrooms from the wild, place the mushroom cap directly onto a sheet of aluminium foil and enclose it together with the rest of the mushroom in the foil. You might have a spore print by the time you return home.
Place the Cap on the Paper:
Use a sheet of white and black paper side by side if you don't know the colour of the spore in advance, as some colours may be difficult to see against a light or dark background. Place the cap of the mushroom, gill-side down, on the paper. If you are using foil, you can clean it with alcohol beforehand to prevent contamination, and it is also easier to transfer spores from foil into your growing medium.
Cover and Wait:
Cover the cap with a glass or container to prevent air currents from dispersing the spores and to prevent the mushroom from drying out. You can also place a piece of wet tissue on top of the cap to keep it moist. Leave the mushroom to sit for 2 to 24 hours, depending on the humidity and the freshness of the mushroom.
Observe the Spore Print:
After the resting time, carefully remove the cap. You should see a colourful imprint of the spores on the paper, which can also show patterns that correspond to the lamellae or pores of the fungus. If you are using foil, you can preserve the spore print by spraying it lightly with an artist spray or hair spray.
Studying the Spores:
To study the spores under a microscope, scrape off some spores from the spore print with a needle or scalpel and place them on a microscope slide. Add a drop of water and cover with a cover slip. Alternatively, you can make the spore print directly on a microscope slide, which is especially useful if you don't know the colour of the spores in advance.

Using a spore syringe
Firstly, you will need to source some magic mushroom spores. These can be found online in the form of spore prints, or you can buy ready-made spore syringes.
To make your own spore syringe, you will need to harvest a mushroom. Put on a pair of nitrile or latex gloves and sterilize them with 70%+ alcohol. Cut off the cap from the stem with a flame-sterilized knife or scissors. Then, use sterilized tweezers to transfer the mushroom cap with the gill side down onto a sterilized piece of wax or parchment paper, or a flame-sterilized sheet of aluminium foil. Use a pipette to drop a couple of drops of sterilized water onto the mushroom cap. Cover it with a bowl and wait for about 24 hours for the spores to drop onto the surface below.
Then, to make a spore syringe, scrape the spore print into a glass with sterilized water and pull the solution into a syringe. You can source syringes from your local pharmacies or order them in bulk online. Ensure you obtain luer-lock syringes as they have a screw-like ending where you can attach a needle or a cap for protection during transport. The standard size for mycology is 10ml.
After preparing the syringe, it is injected into a sterilized substrate where the spores germinate into mycelium. This process typically takes a few weeks under the right conditions of temperature, humidity, and light. Once the mycelium has fully colonized the substrate, fruiting conditions can be introduced to encourage mushroom growth.

Using agar transfers
Agar transfers are an essential skill for mushroom growers, allowing you to cultivate a continuous supply of mycelium, which can be used to inoculate multiple grow bags. This process not only maximises the potential of your initial spore syringe but also saves you money.
Prepare Your Workspace:
Sterility is of the utmost importance. Create a clean environment using a still air box or a laminar flow hood. Spray the entire area with 70% isopropyl alcohol, including your tools and the inside of the still air box.
Sterilise Your Tools:
Use a sterile scalpel, which can be purchased cheaply online, and sterilise it with alcohol before each use.
Transfer the Agar Sample:
Identify the healthiest, uncontaminated section of your agar dish. Use the scalpel to cut a small piece, about the size of a dime, and carefully transfer it into your prepared grow bag. Seal the bag with strong tape, like Gorilla tape, to ensure no contaminants can enter.
Repeat and Monitor:
Repeat the above process for multiple grow bags, using different sections of your agar dish. Place your sealed grow bags in a warm, dark place, and be patient as the mycelium needs time to fully colonise the substrate.
Agar Types:
It is important to understand the different types of agar and their uses. Agar media come in various types, each formulated to serve different purposes. The most common types include Light Malt Extract Agar (LMEA), Potato Dextrose Agar (PDA), and YPD agar. LMEA is suitable for a wide range of mushroom species, while PDA is excellent for spore germination and maintaining mother cultures. YPD agar, on the other hand, provides a conducive environment for the growth of yeasts and moulds but can also be used for certain mushroom species.

Growing from spores
Growing mushrooms from spores can be a challenging and time-consuming process, but it is possible with the right tools and knowledge. Here is a step-by-step guide on how to grow mushrooms from spores:
Collecting Spores:
To collect mushroom spores, you will need a mature mushroom, some paper or foil, and a glass or bowl. Start by gently removing the stem from the mushroom, being careful not to damage the gills. If the mushroom has a skirt, carefully remove it to expose the gills. Place the mushroom gill-side down onto the paper or foil, and cover it with a glass or bowl. Leave it for 24 hours. During this time, the spores will be released and will create a spore print on the paper or foil.
Creating a Spore Syringe:
Once you have your spore print, you can create a spore syringe. Fill a syringe with distilled water that has been boiled 2-3 times to ensure sterility. Rehydrate the spores by injecting the water onto the spore print. Gently mix the spores and water together, being careful not to contaminate the solution. Draw the spore solution back into the syringe, and your spore syringe is now ready for inoculation.
Using an Agar Plate:
An alternative method is to use an agar plate. Transfer a small amount of the spore solution onto a sterile agar plate and wait for it to colonize. Then, carefully remove a clean, non-contaminated sample from the agar and transfer it to a new, sterile agar plate. Repeat this process until you have a clean sample that can be used for further growth.
Inoculating a Growth Medium:
With your spore syringe or clean agar sample, you can now inoculate your chosen growth medium. This could be compost, substrate blocks, or grain, depending on your preference. Keep your growing environment humid and dark to encourage optimal mushroom growth.
Remember, sterility is crucial throughout the entire process to avoid contamination. Always work in a clean environment and sterilize your tools and equipment before each use. Growing mushrooms from spores requires patience and practice, but with dedication, you can successfully cultivate your own mushrooms at home.
