How Are Mushrooms Made: Fascinating Fungi and Their Growth Process
How Are Mushrooms Made?
Mushrooms are made through a process called inoculation.
For commercial farming, mushrooms can be grown indoors on shelves or in plastic bags filled with sterilized sawdust or wood chips.
However, this method creates a lot of plastic waste and requires a significant amount of energy.
An alternative and more sustainable method is log growing, where logs are injected with mushroom mycelium and sawdust to create the colony.
Different types of trees, such as young oak trees, are suitable for growing mushrooms.
The logs are placed in a cool, damp, and dense environment that encourages fungal growth.
After about 8 months, the mushrooms can start fruiting.
This log growing method reduces plastic waste and provides a naturally sterile and sustainable growing medium.
Northwood Mushrooms, a farm in Clayton, WI, uses this method to grow shiitake, lion’s mane, oyster, and nameko mushrooms.

Did You Know?
1. Mushrooms are not actually plants, but rather belong to the fungi kingdom. They are specifically the reproductive structures of certain fungi species, typically growing from an underground network of thread-like structures called mycelium.
2. Some species of mushrooms have the ability to glow in the dark, a phenomenon called bioluminescence. It is believed that this glow helps attract insects, which then spread the mushroom spores to new locations.
3. A giant fungus discovered in the Blue Mountains in Oregon, known as the “Humongous Fungus,” covers an area of approximately 2,385 acres (965 hectares), making it one of the largest living organisms on Earth. It is estimated to be over 2,400 years old.
4. Certain species of mushrooms, like the “Lobster Mushroom,” are not actually mushrooms but rather a parasitic fungus that colonizes other mushroom species, completely transforming their appearance and taste.
5. In ancient Egypt, mushrooms were considered a delicacy and only the pharaohs and royal families were allowed to consume them. They were believed to have magical properties and were often reserved for special occasions or used as offerings to the gods.
Introduction: Understanding The Nature Of Mushrooms
Mushrooms, not plants, are classified as fungi. Fungi, such as mushrooms, have specific growth requirements that differ from those of plants. Understanding these requirements is crucial for successful mushroom cultivation.
Mushrooms flourish in damp and dark environments where there is decaying plant matter. This is because they acquire essential nutrients from the decomposition process. In their natural habitat, mushrooms frequently grow on dead trees, utilizing the abundant organic material available. To recreate these ideal conditions for commercial mushroom farming, specialized facilities and equipment are required.
Commercial Mushroom Farming: Equipment And Facilities
Commercial mushroom farming is a booming industry that is experiencing an increasing demand for mushrooms. One notable farm that excels in mushroom cultivation is Northwood Mushrooms, located in Clayton, Wisconsin.
Mushrooms can be cultivated indoors, providing precise control over climate and lighting conditions. To optimize space and efficiency, mushroom farms often employ shelves in a vertical growing setup. This arrangement allows farmers to grow a significant quantity of mushrooms within a limited area.
However, traditional methods of mushroom cultivation, which involve using plastic bags filled with sterilized sawdust and wood chips, have faced criticism due to the excessive plastic waste they generate. As urban farmers show growing interest in mushrooms, sustainable alternatives to these conventional methods are being explored.
- Indoor cultivation offers better climate and lighting control
- Vertical growing arrangements maximize space and efficiency
- Traditional methods using plastic bags generate excessive plastic waste
“As urban farmers increasingly prioritize sustainability, exploring alternative methods of mushroom cultivation becomes essential.”

Sustainable Mushroom Farming: The Alternative Log Growing Method
The log growing method has been used for centuries and is regarded as a more sustainable option compared to plastic bag cultivation. Logs provide a natural and sterile growing medium for mushrooms, eliminating the need for extensive sterilization processes. Hardwood logs, especially young oak trees, are favored for their suitability for mushroom growth.
At Northwood Mushrooms, sustainability is a priority. They source their logs from neighboring farms and the forest service, promoting forest health and growth. In exchange for helping to maintain and manage forests, the farm obtains logs free of charge, reducing their environmental impact.
The logs are meticulously injected with mushroom mycelium and sawdust during a process known as inoculation. This can be done manually or with the help of pneumatic devices. Once inoculated, the logs are placed in a tented space that is adequately ventilated and well-moistened. These conditions mimic the cool, damp, and dense environment necessary for fungal growth.

Frequently Asked Questions
How are mushrooms formed?
Mushrooms are intriguingly formed through a fascinating process. It all begins with the microscopic spores that mushrooms release into the wild. These spores eventually find their way to the ground or get carried by the wind. In commercial farming, the spores are collected and cultivated on sterile cereal grain, leading to the growth of mycelium, a network of fine filaments. This mycelium, known as ‘spawn,’ is then used to propagate and produce mushrooms. Through this intricate journey, mushrooms are ultimately formed, offering us a wonderful and edible gift from nature.
How are mushrooms processed?
To process mushrooms, they first undergo a series of steps to prolong their shelf life. The process begins by washing the mushrooms in cold water to clean them thoroughly. Next, they are briefly blanched in boiling water for 3-4 minutes, a crucial step to ensure the mushrooms are safe to consume. Following this, the mushrooms are dehydrated using a drier to remove the moisture, helping to enhance their preservation. Finally, the processed mushrooms are packed, and it is highly recommended to treat them in a brine solution beforehand to prevent discoloration.
Is mushroom a veg?
While mushrooms are often classified as a vegetable in cooking and culinary practices, they technically do not fit into the traditional definition of a vegetable. Instead, they belong to the kingdom Fungi. Despite this, mushrooms are commonly consumed and appreciated for their unique taste, texture, and versatility in various cuisines worldwide. Notably, certain mushrooms can also provide a natural source of vitamin D when exposed to ultraviolet light, thanks to the presence of ergosterol, a compound found in their composition. Therefore, mushrooms offer a distinct nutritional profile that sets them apart from both plants and animals.
What is the difference between a mushroom and a fungi?
While mushrooms belong to the kingdom Fungi, they are different from other types of fungi like mildew. There are over 144,000 known species in the kingdom Fungi, which includes mold, yeasts, and rusts. Mushrooms can vary in toxicity and edibility, with some being safe to eat while others can be harmful if consumed or touched. Therefore, the main difference between mushrooms and other fungi lies in their individual characteristics and the potential risks they may pose.
