Mushroom mycelium is a vast network of thin fungal strands called hyphae that lie beneath the soil's surface. This network is often referred to as the woodwide web and is responsible for the mushroom's reproductive structures and root-like functions. Mycelium plays a crucial role in fungal reproduction and communication, forming symbiotic relationships with plant roots and contributing to the health and nutrient intake of plants. It also aids in the decomposition of organic matter, creating soil and maintaining its structure. The depth of this mycelial network can vary, with some reaching impressive sizes, such as the Armillaria ostoyae mycelium in Oregon, which spans 890 hectares.

Mycelium is the vegetative body of a fungus, responsible for the fruiting body or mushroom
Mycelium is the vegetative body of a fungus that forms a network of thin fungal strands called hyphae. It is responsible for the fruiting body of the fungus, commonly known as the mushroom. Mycelium is mostly found below the soil, forming a network that can range from being microscopic to covering colossal areas. For example, an Armillaria ostoyae in Oregon is estimated to cover 890 hectares, making it one of the largest organisms on Earth.
Mycelium plays a crucial role in fungal reproduction. The fusion of two compatible fungi allows their mycelia to combine, facilitating the mixing of their DNA. This network of mycelium is essential for the health and growth of plants and trees. It helps plants and trees absorb water and nutrients from the soil, enhancing their efficiency in water and nutrient absorption. Mycelium also contributes to the organic fraction of soil by breaking down complex organic molecules and converting them into digestible nutrients. This process of decomposition is vital for maintaining healthy soil and providing food for soil-dwelling bacteria and animals.
The mycelium network acts as a communication and transport system, facilitating the exchange of nutrients and electrical impulses. Plants and trees can communicate and share resources through this network, which is often referred to as the "woodwide web." This mutualistic relationship benefits both the fungi and their plant partners. The fungi receive sugars produced by the plants through photosynthesis, while the plants gain access to nutrients trapped in complex organic molecules, which the fungi can obtain through their breakdown process.
Mycelium has practical applications beyond its ecological significance. It can be used in mycofiltration to remove chemicals and microorganisms from soil and water, aiding in the cleanup of oil spills and polluted waterways. Additionally, mycelium has been explored as a material in furniture and artificial leather production, offering an environmentally friendly alternative to animal leather, which contributes to deforestation and greenhouse gas emissions.
In summary, mycelium, the vegetative body of a fungus, is responsible for the fruiting body or mushroom. It forms a vast underground network that facilitates communication, nutrient exchange, and ecological balance. Mycelium plays a critical role in decomposition, soil health, and plant growth while also offering potential solutions to environmental challenges.

Mycelium forms vast networks, connecting plants and trees
Mycelium forms a vast underground network that connects plants and trees. This network is formed by the tiny "threads" of the greater fungal organism that wrap around or bore into tree roots. This network is called a "mycorrhizal network". Mycelium has a similar function in fungi to the roots of plants.
Mycorrhizal networks were discovered in 1997 by Suzanne Simard, a professor of forest ecology at the University of British Columbia in Canada. Mycelium forms a mutualistic association with 83% of plants, acting as an extension of their root systems. Through their mycelium, fungi can partner with the roots of plants, including trees, creating a cross-kingdom web known as a mycorrhizal network. This network connects individual plants and trees, enabling them to transfer water, nitrogen, carbon, phosphorus, and other minerals.
Trees have developed complex symbiotic relationships with mycelium for species survival. When a tree is attacked by harmful organisms, it can alert its neighbouring trees through chemical signals facilitated by mycelium, prompting them to produce defence mechanisms. This symbiotic relationship enhances the overall health of the forest community.
Mycelium also plays a critical role in forest decomposition, breaking down leaves, needles, and other organic matter, transforming them into compost that can be used by other organisms in the forest. This process of breaking down organic matter is critical in maintaining healthy soil and providing food for the bacteria and animals that live there.

Mycelium is essential for decomposing organic matter and creating soil
Mycelium is a network of thin fungal strands called hyphae. It is the root system of mushrooms and connects all life in the woods. Mycelium plays a crucial role in fungal reproduction. The mycelia of two compatible fungi can fuse together, allowing the cells of each fungus to combine and their DNA to mix. This process is known as sexual reproduction in fungi.
Mycelium is essential for decomposing organic matter. It secretes digestive enzymes onto its food source, often dead organic materials, and sometimes living organisms. These enzymes break down the matter into smaller parts that feed not only the fungi but also their plant partners and many other organisms. This process of breaking down organic matter is critical in maintaining healthy soil, recycling leaf litter, and providing food for the vast array of bacteria and animals that live in the soil.
Mycelium is also capable of decomposing otherwise non-degradable materials such as hydrocarbons, plastics, unrefined oil, or even nuclear waste. This ability can be leveraged for environmental cleanup efforts through a process called mycoremediation. Mycelial mats have been suggested as potential biological filters, removing chemicals and microorganisms from soil and water. This process is known as mycofiltration.
Mycelium is also important in creating soil. It excretes acids and enzymes that break down organic matter and even rock. Saprophytic mushrooms and their mycelium networks use these acids and enzymes to decompose fallen leaves, plants, and trees, as well as dead animals, insects, and birds. These networks contribute to the organic fraction of soil. Mycelium holds soils together, helps aerate them, and increases the efficiency of water and nutrient absorption of most plants.

Mycelium is a primary factor in some plants' health, nutrient intake and growth
Mycelium is a network of thin, root-like fungal strands called hyphae. It is found in and on the soil and many other substrates. Mycelium plays a crucial role in the health, nutrient intake, and growth of some plants.
Mycelium is an important factor in the decomposition of organic matter, breaking it down into simpler molecules that become part of the broader ecosystem. This process is essential for maintaining healthy soil and providing food for soil-dwelling bacteria and animals. Mycelium also contributes to the organic fraction of soil, with mycelial networks constituting 20-30% of soil biomass.
Through their mycelium, fungi can form symbiotic relationships with plant roots, creating a cross-kingdom web known as mycorrhizal networks. This partnership allows fungi to obtain sugars and fats from plants through their roots, while the fungi help the plants absorb water and nutrients from the soil beyond the reach of their roots. Mycelial networks can also transport water and electrical signals, which may allow plants to communicate within an ecosystem.
The mutualistic relationship between mycelium and plants is initiated by hyphal connections, where mycelial strands attach themselves to plant hyphae, penetrating the cell wall. This interaction facilitates the exchange of nutrients and the transmission of electrophysiological signals. Different fungi supply varying levels of nutrients and growth-promoting materials, with plants tending to root towards fungi that provide the most essential minerals for their growth.
In addition to its ecological significance, mycelium has gained interest as a nutrient-dense food source that can help address world hunger and promote health. Mycelium is low in total fat, primarily containing unsaturated fat, and is a source of fiber. It has a high protein content, ranging from 20-30% on a dry matter basis, and provides essential amino acids. The filamentous nature of mycelium also allows for the development of meat-mimetic products with improved nutritional profiles and fewer additives.
