Cloning mushrooms is a great way to cultivate and preserve unique strains found in nature, helping to maintain genetic diversity among cultivated mushrooms. It is a simple process that involves scraping tissue from a mushroom under sterile conditions and placing it onto a sterile medium to grow. This allows you to create an identical copy of a mushroom with desirable traits such as yield, speed of growth, colour, and disease resistance. When cloning a mushroom cluster, it is important to choose a rapidly growing fruit from the middle of the cluster and expose its virgin tissue. By tearing the mushroom in half and using a sterile instrument, a tiny piece of tissue can be scraped out from the centre of the fruit, which can then be placed onto agar to grow. This process can be applied to both wild mushrooms and store-bought mushrooms, providing a fun and easy way for anyone to explore the fascinating world of mycology.

Choosing the right mushroom to clone
When choosing the right mushroom to clone, there are several factors to consider. Firstly, it is essential to select a healthy and fully-developed mushroom with desirable traits. Avoid specimens with signs of contamination or disease, as these issues may persist in the cloned mycelium. The mushroom should be fresh, as the cloning process is more challenging with dried mushrooms due to the increased risk of tissue damage during the drying process. However, dried mushrooms can still be cloned by first hydrating them in sterilized water.
The chosen mushroom should exhibit the desired characteristics you wish to cultivate, such as rapid growth, large fruiting bodies, or high potency, depending on the intended use of the mushrooms. If you are seeking a high yield, selecting a mushroom with rapid cell division is ideal as it will take off quickly on agar. Additionally, choosing a young, rapidly growing fruit or cluster is recommended for optimal results. Smaller fruits are preferable as they have a higher concentration of active product per gram, and cloning from a cluster will result in larger flushes of smaller fruits.
When selecting the tissue to clone, it is best to take a small piece of tissue from the stem (stipe) as it has a lower risk of contamination. The tissue sample should be about half the size of a grain of rice, and you can use distilled water to wash it and remove any remaining contaminants. It is crucial to work in a sterile environment and wear protective gear, such as gloves and a mask, to prevent contamination from handling.
By choosing a mushroom with desirable traits and following good cloning practices, you can successfully replicate the genetic material and produce a consistent, high-quality harvest. Remember that you can clone wild mushrooms, store-bought mushrooms, or those you have cultivated yourself.

Preparing your work area and tools
To clone a mushroom cluster, you must first prepare your work area and tools. This process is crucial, as it ensures a sterile environment for your mushroom clone to grow successfully without contamination. Here are the steps to prepare your work area and tools for cloning mushroom clusters:
Choose a Suitable Work Area
Select a clean and sanitised workspace, such as a laminar flow hood or a still air box (SAB). These environments help minimise contamination risks by providing controlled conditions. If you don't have access to specialised equipment, you can create a sterile workspace by thoroughly cleaning and sanitising an area.
Gather the Necessary Tools and Supplies
You will need various tools and supplies for the cloning process. Here is a list of what you will require:
- Sterile scalpel or sharp instrument (e.g., X-Acto knife): Used for tissue removal and transfer. It is essential to ensure your instrument is sharp and sterilisable.
- Sterilising agents: Isopropyl alcohol, a bleach solution, or another effective sanitising agent. These are crucial for cleaning surfaces, tools, and even the exterior of your mushroom sample.
- Disposable gloves: Gloves help maintain sterility during the process. Remember to sanitise your gloves as well.
- Parafilm or masking tape: Used for sealing agar plates to prevent contamination.
- Agar plates or petri dishes: These contain a sterile, nutrient-rich agar solution derived from red algae. Agar provides the necessary nutrients for mycelium growth and helps maintain a sterile environment. You can purchase ready-made agar plates or create your own growing medium using powdered agar.
Prepare the Mushroom Sample
Choose a fresh, healthy mushroom fruiting body with desirable traits, such as rapid growth or large fruiting bodies. It is recommended to select young, rapidly growing mushrooms, as they have actively dividing cells, which will facilitate quicker growth on agar. Clean the exterior of your chosen mushroom sample with a sterilising agent to ensure it is free from contamination.
Prepare Your Tools
Sanitise your tools, including your gloves and scalpel, with alcohol or another suitable sterilising agent. Ensure that your work area is free from potential contaminants, and all your supplies are easily accessible.
By following these steps, you will have a sterile work area and the necessary tools ready for the cloning process. Remember, maintaining a clean and controlled environment is crucial to successfully cloning mushroom clusters.

Scraping and transferring the mushroom tissue
Selecting the Mushroom:
When choosing a mushroom to clone, look for a young, fresh, and healthy specimen with desirable traits, such as rapid growth or large fruiting bodies. The mushroom should be in its button stage, as mushrooms at this stage grow fast and have rapidly dividing cells. Avoid older mushrooms as the cells stop dividing, and the risk of contamination increases.
Preparing the Workspace:
It is essential to work in a sterile environment to minimize contamination. Use a laminar flow hood or a still air box (SAB) to create a controlled environment. Clean and sanitize your workspace, including the hood or SAB, with isopropyl alcohol, bleach solution, or another effective sterilizing agent. Ensure all your supplies, such as gloves, scalpel or X-Acto knife, and agar plates, are within reach and sterilized.
Scraping the Tissue:
Put on your disposable gloves and clean the exterior of the mushroom with a sterilizing agent. Carefully remove a small piece of internal mushroom tissue, about the size of a grain of rice. You can use a flame-sterilized scalpel to scrape or cut the tissue from the center of the mushroom. Avoid using gill tissue as it may be contaminated with spores. The fleshiest and innermost parts of the mushroom, such as the interior of the cap or the stem, are ideal for tissue collection.
Transferring the Tissue:
Place the scraped tissue onto a sterile growth medium, such as an agar plate. Agar plates provide a nutrient-rich environment for the mycelium to grow. Transfer the tissue to the center of the medium, and you may choose to place more than one piece of tissue for better success rates. Immediately close the agar plate to minimize contamination.
Storing the Agar Plate:
Seal the agar plate with parafilm or masking tape to prevent contaminants from entering. Label the plate with the date and mushroom strain information. Store the plate in a dark, temperature-controlled environment, typically around 70-75°F (21-24°C).
Remember, the key to successful mushroom cloning is maintaining sterility throughout the process to avoid contamination. With proper techniques and attention to detail, you can effectively scrape and transfer mushroom tissue to create clones.

Using agar to grow clones
To clone mushrooms using agar, start by selecting a fresh, healthy mushroom with desirable traits and a relatively large fruiting body. Clean the surface of the mushroom with alcohol to sterilize it. Using a sterile scalpel or razor blade, carefully remove a small piece of internal mushroom tissue, about the size of a grain of rice, from the fleshiest and innermost part of the mushroom, such as the interior of the cap or the stem. Avoid using gill tissue as it is often contaminated with spores. Transfer the tissue to a pre-poured or homemade agar plate, placing it in the centre of the medium. Close the agar plate immediately to minimize contamination risk.
Over the next few days, the mushroom tissue will grow into mycelium, the vegetative part of a fungus that grows underground and absorbs nutrients. Mycelium can be collected from the agar plate and transferred to a new sterile medium, such as another agar plate or sterilized grain, to expand the culture and propagate mycelium for future cultivation projects. This process can be repeated to create multiple generations of clones, preserving the genetics of the original mushroom strain.
It is important to note that with each subsequent generation, the risk of genetic drift and potential loss of desirable traits may increase. Therefore, it is recommended to use only a few generations of clones for the best results. Additionally, cloning mushrooms require a certain level of skill and knowledge, as it is a delicate process that demands attention to detail and patience.

Storing your clones and preserving genetics
Storing your mushroom clones and preserving their genetics is an important part of the cloning process. If you're not able to clone the mushroom immediately after harvesting it, you can store it in the fridge for up to 48 hours. It is recommended to clone the mushrooms as soon as possible, as older mushrooms are harder to germinate and the risk of contamination increases with time.
To store your mushroom clones for longer periods, you can use agar plates, which are petri dishes containing a sterile, nutrient-rich agar solution derived from red algae. Agar plates allow you to store your mushroom mycelium for extended periods, reduce contamination chances, and provide an opportunity to remove any contaminants. You can purchase pre-made agar plates or create your own growing medium using powdered agar. However, ensuring a sterile environment is crucial when working with agar to prevent contamination.
Another storage method is to use grain spawn, which involves using sterilized jars of grain instead of agar plates. While this method doesn't provide the same visibility into infections as agar, it is still a viable option for cloning mushrooms.
Additionally, you can store mushroom tissue for long-term use by regularly transferring it to new plates (approximately every four weeks) to maintain its vitality. Wrapping the tissue in parafilm helps reduce contamination and drying out. It is also recommended to keep a backup plate that remains unopened to protect against contamination during transfers.
For those seeking to preserve mushroom cultures for extended periods, a 20-degree Celsius freezer can be an option. This temperature range helps to stunt growth without stopping it entirely, allowing for long-term preservation.
