Cultivating Amanita muscaria in controlled settings is essentially impossible due to its specific ecological requirements and mycorrhizal associations with certain trees.
As of my last update in January 2022, there hasn't been widespread or mainstream scientific effort to cultivate Amanita muscaria in controlled settings for commercial or research purposes due to its unique symbiotic relationship with specific tree species. Most research related to Amanita muscaria focuses on its biology, ecology, chemistry, and potential pharmacological effects rather than cultivation.
Mycorrhizal Mushroom
Amanita muscaria forms a mycorrhizal relationship with various tree species, particularly with members of the Pinaceae family, such as pines, spruces, and firs. This symbiotic relationship is mutualistic, benefiting both the fungus and the host tree.
1. Nutrient Exchange: The fungus colonizes the tree's root system, forming a network known as mycelium. This mycelial network extends the tree's root system, increasing its ability to absorb water and essential nutrients like phosphorus and nitrogen from the soil.
2. Protection: In return, the tree provides the fungus with sugars and other organic compounds produced through photosynthesis. The mycorrhizal association can also help protect the tree from certain pathogens by forming a barrier around the tree roots or producing compounds that deter harmful organisms.
3. Ecological Importance: This symbiotic relationship plays a vital role in forest ecosystems. It enhances soil structure, improves nutrient cycling, and contributes to the overall health and vitality of forest ecosystems where these trees and fungi coexist. The specificity of Amanita muscaria's mycorrhizal associations with certain tree species is essential for its ecological niche. Without these specific tree hosts, the mushroom would not thrive, emphasizing the intricate and specialized nature of mycorrhizal relationships in ecosystems.
The complexities and specific ecological requirements of this mushroom make it challenging to cultivate on a commercial scale compared to other mushrooms that have been domesticated for cultivation.
Slurry
The best way at this point is to create a slurry and try to "seed" new areas. Keep in mind that most attempts at this fail 85% of the time, even if seeding the same area year after year. I have created a slurry that has been about 76% successful so far and you can watch the video about how to do it here: Slurry Video
