Store-bought mushrooms can be used to propagate mycelium
To propagate mycelium from store-bought mushrooms, you can use the following methods:
Using Mushroom Stems
One method is to use the stems of store-bought mushrooms, as they often contain mycelium. Cut the stems into small pieces, about 1/4 inch (6 mm) in size. You can then place these pieces into a container with a moistened cellulose material, such as straw, hamster bedding, or shredded cardboard. Layer the container with the mushroom stem pieces and moist material, ensuring that everything remains damp and in a dark place with temperatures between 65 to 75 degrees F (18-23 C).
Using Spores
Another method is to collect the spores from store-bought mushrooms and then grow the mycelium from those spores. To collect spores, remove the stem from a fresh mushroom and place the cap gill-side down onto a piece of paper or sterilized foil. Add a drop of water to the cap and cover it with a bowl for 24 hours. After removing the bowl and cap, you should see the spores. You can then inject the spores into a disinfected grow bag and place it in a warm, dark area to facilitate growth.
It is important to note that propagating mycelium from store-bought mushrooms requires a good fruiting medium, moisture, and the proper growing environment. Additionally, make sure to choose mushrooms from organic sources and always identify wild mushrooms before consuming them.

You can extract spores from store-bought mushrooms
Yes, you can extract spores from store-bought mushrooms. The process is simple and allows you to grow your own mushrooms or create natural prints for art. Here is a step-by-step guide on how to extract spores from store-bought mushrooms:
Selecting the Mushrooms:
Choose fresh, healthy mushrooms with large caps for best results. You can use any variety of mushrooms as long as they are fresh. Check for mould, brown spots, and mushy areas. Unhealthy mushrooms may not produce spores. Make sure the cap is firm and not wet or mushy. Flip the mushroom over and ensure the gills are moist; dry gills are less likely to release spores.
Preparing the Setup:
You will need a bowl, water, paper or aluminium foil, and optionally, gloves and scissors or a knife. If you want to reduce the risk of contamination, wear gloves sterilized with 70% rubbing alcohol. Sterilize the scissors or knife by holding them over a flame until they turn red hot, then dip them into distilled water. You can also sterilize a piece of wax paper or aluminium foil with 70% rubbing alcohol or by holding it over a flame.
Extracting the Spores:
Remove the stem from the mushroom, either by cutting it at the base with scissors or a knife or by pulling it out, as it usually separates easily. If the top of the cap grows over the gills, use a heat-sterilized knife to carefully carve out the skirt of the cap, avoiding the gills. Place the cap gill-side down onto the paper or foil. If you want to keep the stem attached, cut a hole in a piece of paper or cardboard, insert the stem, and place the cap on the paper. Add a drop of water on the cap and cover it with a bowl. Let it sit for 24 hours.
Harvesting the Spores:
After 24 hours, remove the bowl and cap to reveal the spores on the paper or foil. You can now use these spores for growing mushrooms or creating natural prints. If you plan to grow the mushrooms for consumption, ensure you use an edible variety. Store the spores in a dry, cool, and dark place, like an airtight container, to keep them viable for up to a year.
By following these steps, you can successfully extract spores from store-bought mushrooms and explore the fascinating world of mycology or create unique natural art.

Oyster mushrooms are a great place to start
Oyster mushrooms are one of the most common mushrooms found on hardwoods throughout the north temperate zone, and they also occur on conifers. Many species of oyster mushrooms are commonly cultivated, including the most popular P. ostreatus and P. pulmonarius. They can grow on the dead wood inside living trees. Oyster mushrooms fruit throughout the year whenever conditions are favourable.
There are several different types of oyster mushrooms to choose from, each with its own unique characteristics and preferences. For example, the pearl oyster mushroom is one of the most commonly available varieties and grows best in colder temperatures. The blue oyster mushroom is a subspecies of the common oyster and is one of the fastest colonizers, preferring cooler temperatures as well. The phoenix oyster mushroom, also known as the summer oyster mushroom, has evolved to grow in warmer climates. The golden oyster mushroom, or yellow oyster mushroom, is known for its amazing colour and similarity to the popular chanterelle mushroom. It prefers warmer temperatures as well. The pink oyster mushroom is one of the most striking varieties and grows quickly, producing fruits in as little as 3-4 weeks. It also prefers warmer temperatures.
Growing oyster mushrooms can be done both indoors and outdoors, although growing them indoors provides more predictable results as it is easier to control the temperature and elements. The first step is to decide on the type of oyster mushroom you want to grow, as each variety has its own temperature and humidity preferences. The most widely used substrate for oyster mushrooms is straw, but other materials such as sawdust, cardboard, coffee grounds, and agricultural byproducts can also be used. Wood pellets are a good option for beginners as they come already pasteurized and only require the addition of water.
Once you have your substrate and spawn, you can follow these general steps:
- Mix the spawn with the substrate and cover it.
- Place the mixture in a warm, sheltered environment above 70°F (21°C) and maintain high humidity.
- White thread-like mycelium should develop and cover the mixture within a few days.
- Once covered in white mycelium, move the mixture to a location with indirect light and maintain the temperature and humidity.
- Cut slits into the growing bag or container to allow air circulation and for the mushrooms to grow through.
- Oyster mushrooms should start growing after about a week to 10 days.

The best size for growing mushrooms from store-bought stems is 1/4 inch (6mm)
Mushrooms can be grown from spores or from the stems of store-bought mushrooms. The latter is a quicker process because you don't need to rely on spores and can use the mycelium already on the fungi. The best size for growing mushrooms from store-bought stems is 1/4 inch (6mm). The stems should be cut at an angle and spread out on a substrate. The substrate should be damp and covered with plastic wrap or a plastic bag with holes poked in it to allow for airflow. The container should then be placed in a dark spot away from drafts, such as a closet, shelf, or under the sink. It is important to ensure that the substrate does not dry out, and it can be misted with fresh water if necessary.
To grow mushrooms from spores, you will need to extract the spores from a fresh, healthy mushroom. This can be done by removing the stem from the mushroom and placing the cap gill-side down onto a piece of paper or sterilized tin foil. A drop of water is then placed on the cap, which is covered with a bowl and left for 24 hours. The bowl and cap can then be removed, revealing the spores. Spores can also be purchased if you don't want to extract them yourself.
Once you have spores, you will need to research what kind of grow bag to buy or make. The grow bag should be disinfected and injected with 20-40 mL of spores. It should then be shaken and placed in a warm, dark area with a temperature between 60 to 75 °F (16 to 24 °C). If you don't see mycelium spreading through the bag after ten days, you may need to shake it again.
Overall, growing mushrooms from store-bought stems is a quicker and easier process than growing from spores, and the best size for the stems is 1/4 inch (6mm).

You can use a cardboard box, paper bags, or a plastic bin to layer your medium
To grow mushrooms, you'll need a suitable growing medium, such as cardboard, paper, or plastic. Cardboard is a cheap and readily available material that can be used to grow mushrooms. It is lightweight and easy to move around, and it is also considered safe for mushroom growth, as long as it is not treated with waxes, fungicides, or other chemicals. Make sure to use brown corrugated cardboard made of recycled materials and unbleached paper products.
To prepare your cardboard growing medium, start by sanitizing your workspace and gathering your materials. Soak pieces of corrugated cardboard in water, shake off the excess water, and then layer them in a container or tote, sandwiching mushroom spawn or stem butts between the layers. Drill holes in the bottom and sides of the container for drainage and airflow. Place the container in a cool, dark place for two to three weeks until it is fully colonized by the mushroom mycelium.
If you prefer to use paper bags as your growing medium, you can follow a similar process. Disinfect the paper bags and inject them with mushroom spores or a slurry of mushroom spawn and growth media. Seal the injection hole and place the bags in a warm, dark area to facilitate colonization. Shake the bags periodically to mix the spores or spawn into the medium.
Using a plastic bin as your growing medium also offers a suitable environment for mushroom growth. Sanitize your plastic bin and create a slurry of growth media, such as coffee grounds or grain substrate, mixed with mushroom spores or spawn. Place the slurry in the bin and cover it with a layer of vermiculite to help maintain proper humidity. Ensure adequate airflow by leaving the lid of the bin slightly ajar or using a fully automated system to control environmental conditions.
Whether you choose cardboard, paper bags, or a plastic bin as your growing medium, maintaining proper moisture content and a humid environment is crucial for successful mushroom growth. Additionally, providing indirect light from a window or artificial lighting for 12 hours a day can promote optimal growth conditions. With patience and the right conditions, you'll be well on your way to cultivating a bountiful mushroom harvest.
