Can Dried Mushrooms be Used to Grow New Ones?

Key Takeaways

  • Dried mushrooms can be used to grow new ones
  • The viability of spores within the dried mushrooms is crucial for successful growth
  • Steps for growing new mushrooms from dried ones include identifying the species, rehydrating the mushrooms, collecting the spores, adding them to a growing medium, and incubating the medium

Yes, dried mushrooms can indeed be used to grow new ones. Whether you are a mushroom enthusiast or a farmer looking to start a mushroom farm, utilizing dried mushrooms can be a cost-effective and convenient way to kickstart the cultivation process. However, there are several factors that need to be considered to ensure successful mushroom growth. In this article, we will explore the viability of using dried mushrooms for mushroom cultivation, the importance of spore viability, suitable dehydration methods, and the necessary steps to grow new mushrooms from dried ones.

The Viability of Dried Mushrooms

According to various sources, including WhyFarmIt and SporesMD, dried mushrooms can be used for mushroom cultivation. However, the key factor to consider is the viability of the spores within the dried mushrooms. If the spores are still viable, they have the potential to germinate and grow into new mushrooms.

It is important to note that the viability of spores can be affected by various factors, such as the drying method used, the duration of drying, and the storage conditions of the dried mushrooms. If the spores are too dehydrated or dead, they will not be able to initiate the growth process. Therefore, it is crucial to ensure that the spores are still viable before attempting to grow new mushrooms from dried ones.

Dehydration Methods and Preservation of Spores

When drying mushrooms for the purpose of cultivating new ones, it is essential to choose an appropriate dehydration method. According to Evergreen Seeds, the drying process should be done at room temperature to preserve the spores effectively. High temperatures can lead to the death of spores, rendering them nonviable for cultivation.

Additionally, the duration of drying should be taken into consideration. The longer the mushrooms are dried, the higher the likelihood that the spores may lose their viability. It is recommended to dry the mushrooms until they are crisp, but not excessively dehydrated. This will help maintain the viability of spores and increase the chances of successful mushroom growth.

The Process of Growing New Mushrooms

To grow new mushrooms from dried ones, a series of steps need to be followed. These steps are outlined below:

  1. Correctly identify the dried mushroom species: It is crucial to identify the mushroom species accurately before attempting to grow them. Different mushrooms have varying growth requirements, so it is important to ensure that the species is suitable for cultivation.
  2. Rehydrate the dried mushrooms: Before collecting the spores, it is necessary to rehydrate the dried mushrooms. This can be done by soaking them in water for a period of time, typically overnight. Rehydration helps revive the mushrooms and prepare them for spore collection.
  3. Collect the spores: Once the mushrooms are rehydrated, the spores can be collected. This can be done by gently tapping the cap of the mushroom onto a clean surface, such as a piece of paper. The spores will be released and can be collected for later use.
  4. Add spores to a growing medium: The collected spores can be added to a suitable growing medium. This can be a mixture of materials such as compost, straw, and wood chips, depending on the mushroom species being cultivated.
  5. Incubate the growing medium: The growing medium, containing the spores, should be placed in a suitable environment for incubation. Different mushroom species have different temperature requirements for optimal growth. It is important to research and maintain the appropriate temperature for successful cultivation.

By following these steps, it is possible to grow new mushrooms from dried ones, provided that the spores within the dried mushrooms are still viable.


In conclusion, dried mushrooms can indeed be used to grow new ones, but the viability of spores is a crucial factor to consider. The drying method, duration of drying, and storage conditions of the dried mushrooms all impact the viability of spores. It is important to correctly identify the mushroom species, choose an appropriate dehydration method, and rehydrate the mushrooms before collecting the spores. By following the necessary steps, new mushrooms can be cultivated from dried ones. However, it is always recommended to ensure the viability of spores and conduct thorough research on the specific requirements of the mushroom species being cultivated.
