Mushrooms are the fruiting, above-ground bodies of the subterranean species mycelium. The spores produced by mushrooms are borne on the wind, various creatures, and water runoff to new locations. The mycelium, which is the vegetating part of the fungus, spreads into new niches and novel surroundings—ready to do it all again. The reproductive bodies of fungi, mushrooms' purpose in life, is to produce spores, or seeds. Each type of fungus has a different spore type and releases them in unique patterns depending upon the form of the underside of the mushroom cap. Gill mushrooms are the easiest from which to harvest spores, but with some experimentation, all types can be harvested. The spores are microscopic in size but contain the blueprint for new mushroom growth. A mature mushroom is said to contain up to 16 billion spores and so this gives plenty of opportunities to propagate. There are several ways to capture mushroom spores, including spore prints, spore syringes, and spore solutions.

What You'll Learn
Making a spore print
To make a spore print, you will need a mature mushroom with visible gills, such as an oyster, portobello, or Swiss brown mushroom. You will also need a piece of white paper, a piece of black paper, and a glass container that can be inverted over the mushroom. The purpose of using two colours of paper is to ensure that the spores, regardless of their shade, are visible.
Remove the stem from the mushroom and place the cap spore side down onto the two pieces of paper, with half on white and the other half on black. Cover the mushroom with the glass container to prevent it from drying out and to maintain humidity. Leave the setup overnight, and by the next day, the spores would have dropped from the cap onto the paper, forming a spore print. If you wish to preserve the spore print, you can spray it with a fixative or hairspray.
The spore print can then be used to grow mushrooms. This is done by creating a spore syringe, where the spores are rehydrated using sterile water and then used to inoculate the growing medium. To create a spore syringe, work in a sterilised environment and use distilled water that has been boiled two or three times to ensure any bacteria has been eliminated.

Using a spore syringe
Spore syringes are a convenient tool for mycology tasks, enabling researchers to isolate, grow, and study specific mushroom strains for scientific investigations. They are also used to propagate fungi, allowing for controlled inoculation onto various substrates.
To create a spore syringe, you need to work in a sterilised environment and with distilled water that has been boiled 2 or 3 times to ensure that any bacteria have been eliminated. First, fill a glass with distilled water, using a little more water than what you will need to fill up all your spore syringes. Cover the glass with aluminium foil and place it in a pressure cooker. Place aluminium foil over all other items you want to sterilise, including the syringes, and put them in the pressure cooker as well. After pressure-cooking the equipment for at least 15 minutes, let it cool down.
When you are ready to make a spore syringe, wipe down the inside of the sterile box and the gloves with alcohol, and then spray the inside of the box with Lysol. Move the equipment you need inside the sterile box and snap on the cover. Make sure your syringe needle is sterile by holding it in a flame for a few seconds. Draw some of the cooled, sterilised water into the syringe body. Using the syringe needle, lightly scrape the spores from your spore print into a sterilised glass. Expel half of the water from the syringe into the glass. Draw the spore water back into the syringe. At this point, you should notice that the water has become slightly discoloured, and you may even be able to see some floating clusters of spores.
Once you are happy with the amount of spores you have transported into your water, draw the spore solution up into the syringe. The mushroom spores will most likely be sitting on the surface of the water, so it is helpful to draw some water up and then deposit it back into the glass to help disperse the spores evenly throughout the water. Repeat this process if you are making multiple spore syringes. Once the spores are mixed through the water, draw your spore water up, trying to avoid any air bubbles, and stick a syringe cap or needle on the end of your syringe. Repeat for all the remaining syringes. Once you have all your syringes made, it is best to leave them for a couple of days before using them to allow the spores to become fully hydrated.

Growing from spore solution
Growing mushrooms from a spore solution is a delicate process that requires a specific set of steps and a great deal of knowledge. Here is a detailed guide on how to grow mushrooms from a spore solution:
Collecting Spores
The first step in growing mushrooms from spores is to collect the spores. This process is relatively easy and simply requires a mushroom, some paper, and a glass. Start by selecting a fresh, mature mushroom with a large cap to ensure a higher yield of spores. Check that the mushroom is firm, dry, and healthy, with moist gills, as old and wet mushrooms are less likely to produce spores. Place the mushroom gill-side down onto a piece of sterilized paper or aluminium foil. If your mushroom has a skirt, use a heat-sterilized knife to carefully remove it without damaging the gills. Put a drop of water on the cap and cover it with a glass bowl to prevent it from drying out. Leave it for 24 hours.
Creating a Spore Syringe
After 24 hours, remove the glass bowl and the mushroom cap. You should see a spore print on the paper, which is the result of the spores falling from the cap. This spore print contains the genetic material of the mushroom, allowing for the cultivation of specific strains or types of mushrooms. To create a spore syringe, rehydrate the spores with sterile distilled water that has been boiled 2-3 times to eliminate any bacteria. Use a sterile syringe and needle, ensuring the needle is sterilized by holding it in a flame for a few seconds. Scrape the spore print into the distilled water and fill the syringe.
Selecting a Growth Medium
Different mushrooms prefer different growing media. Common substrates include wood, manure, grain, or straw. Research the specific type of mushroom you are trying to grow to determine the most suitable growth medium. For example, oyster, shiitake, and chicken of the woods mushrooms grow well on wood, while portobello mushrooms prefer manure.
Inoculating the Substrate
Once you have prepared your growth medium, use the spore syringe to inoculate the substrate. This involves injecting the spore solution into the substrate, such as compost or substrate blocks. Keep the conditions humid and dark to encourage mushroom growth.
Maintaining the Environment
Mushrooms require a specific environment to thrive. Ensure that the substrate remains moist and that the temperature and humidity levels are optimal for mushroom growth. Keep the growing area free from contaminants to prevent the growth of unwanted microorganisms.
Growing mushrooms from a spore solution is a rewarding process that allows you to witness the miraculous growth of fungi. It requires patience, attention to detail, and a basic understanding of mycology.

Using foil to collect spores
To collect mushroom spores, you will need a fresh and healthy mushroom, a bowl, some water, and a piece of foil. Firstly, cut off the stem of the mushroom, ensuring you cut as close to the gills as possible. If you want to keep the stem attached, you can cut a hole in a piece of card and place it over a bowl, inserting the stem into the hole so the cap rests on the bowl.
Place the mushroom cap, gill-side down, onto a piece of foil. Ensure the gills are close enough to the surface without touching it directly, as this could introduce bacteria. Put a drop of water on the cap, then cover it with a bowl and leave it for 2-24 hours. The spores will fall from the gills and settle on the foil, creating a spore print pattern.
After the allotted time, carefully remove the bowl and cap to reveal the spores. If you want to preserve the spores, you can fold over the foil and store it in a ziplock bag. Spore prints can be stored at room temperature and can last for years, or even indefinitely if stored correctly. To preserve the spores, you can spray them lightly with an artist spray or hairspray.

Preserving spore prints
To preserve spore prints, it is important to dry them first. Then, store the dried prints in a cool, dark, and dry place. A shelf in the middle of a cupboard or drawer is ideal, as it is free from the daily disruptions of the door opening and shutting. The temperature should be between 2°C and 10°C (35°F and 50°F). Spore prints can be stored in a parchment paper envelope or a ziplock bag to keep them secure from contamination and moisture. An airtight container can also be used to minimise moisture exposure from the surroundings.
It is important to avoid humidity, as it could be detrimental to the preservation of spore prints. Additionally, light exposure can degrade spores and reduce their viability, so it is best to avoid direct light and maintain a dark environment.
With proper storage, spore prints can be preserved for extended periods, unlocking the potential of your mushroom cultivation adventures.

Frequently asked questions
The easiest way to capture mushroom spores is by making a spore print. This method is commonly used by mycologists to identify a fungus.
To make a spore print, you'll need a mature mushroom with visible gills, a piece of paper (white or black depending on the colour of the gills), and a glass container. Remove the stem from the mushroom, place the cap with the gills facing down onto the paper, and cover it with the glass container. Leave it overnight, and by the next day, the spores will have dropped onto the paper in a pattern that replicates the gill structure.
To store the spore print, use sterilised tweezers to transfer the print into a zip-seal bag. Keep the bag in a cool, dry, and dark place until you're ready to use it for cultivation.
To grow mushrooms, you can create a spore syringe by rehydrating the spores with sterile water and then using it to inoculate a growing medium, such as compost or substrate blocks. Alternatively, you can mix the spores with water and spray them onto an appropriate substrate, but this method may result in higher contamination.
