Mushrooms are a type of fungus, and like other fungi, they play an essential role in the ecosystem. The part of the mushroom that is visible to us is called the fruiting body or cap, and underneath this are the spores, which facilitate reproduction. However, the focus of this discussion is the third part of the mushroom: the mycelium. This is the root system or vegetative body of the mushroom, a network of thin filaments called hyphae that intertwine with the substrate the fungus is growing on, such as wood, soil, or compost. The mycelium is responsible for collecting food, water, and nutrients to nourish the fungus and plays a crucial role in fungal reproduction.

What You'll Learn
Mycelium is the root system of mushrooms
The mycelium is an essential part of the fungus, serving the same purpose as roots do for plants. It collects food, water, and nutrients to nourish the fungus, providing support and anchorage for the mushroom. The mycelium secretes digestive enzymes onto its food source, often dead organic materials, and sometimes living organisms, to break them down and extract nutrients. This process of decomposing organic matter and recycling it into beneficial compounds for the soil food web is known as mycoremediation.
The mycelium also plays a crucial role in fungal reproduction. The mycelia of two compatible fungi can fuse together, allowing their cells to combine and their DNA to mix. This fusion results in the formation of new spores, which are held inside (as in truffles) or exposed outside (as in mushrooms) the fungus' reproductive structures. This is how some fungi reproduce when the environmental conditions are favourable.
Additionally, mycelium has been found to have several eco-friendly uses. It can act as a binder for disturbed soil, preventing washouts until plants can establish roots. Mycelium is also being used to create artificial leather, grown using liquid-state or solid-state fermentation. This fungal-based leather is cheaper and more environmentally friendly than traditional and synthetic leather, as it is biodegradable and has a lower environmental footprint.

Mycelium is used to make artificial leather
Mushrooms are a type of fungus, and mycelium is a part of the fungal organism. Mycelium is a dense network of thin filaments called hyphae, each surrounded by a robust fungal cell wall. This network collects food, water, and nutrients to nourish the fungus and provides support and anchorage for the mushroom.
Fungal-based artificial leather, such as Mylo™, offers a more sustainable option. It is cheaper to produce, has a lower environmental impact, and is biodegradable. Mycelium is grown using liquid-state or solid-state fermentation, with companies using laboratory media or agricultural byproducts to cultivate fungal biomass. The mycelium is then processed and dyed to create a material that looks and feels like animal leather.
The process of creating mycelium-based leather involves the plasticizing and crosslinking of mycelial mats with various reagents to achieve the desired leather properties. Protein- and lipid-based plasticizers are used to reduce brittleness and hardness, while polysaccharides and polyphenolic compounds may be employed to increase stiffness. The use of natural and biodegradable plasticizers with low toxicity and good compatibility is essential in the production of mycelium-based leather.
Mycelium-based leather is derived from Polyporales, where lignocellulosic material serves as the substrate. This substrate can be agro-waste, making the production process environmentally friendly by utilizing waste materials. The resulting leather is soft, supple, and less harmful to the environment, providing consumers with an ethical and sustainable alternative to conventional animal-based leather.

Mycelium is a food source for soil invertebrates
Mushrooms are a type of fungus, and the part of the fungus that we typically eat is called the "fruiting body". Underneath the mushroom cap lies a hidden part of the fungus called the mycelium. This is a dense mass of thread-like filaments called hyphae, which form a network that is similar to the root system of a plant.
The mycelium plays a crucial role in the ecosystem. It helps fungi absorb nutrients from its environment by secreting digestive enzymes onto its food source, which is often dead organic material, such as wood, and sometimes living organisms. This process of breaking down organic matter is critical in maintaining healthy soil, recycling leaf litter, and providing food for the bacteria and animals that live in the soil.
Mycelium is an important food source for many soil invertebrates. It is also vital to agriculture and is important to almost all species of plants, with many plants co-evolving with the fungi. Mycelium is a primary factor in some plants' health, nutrient intake, and growth, and it increases the efficiency of water and nutrient absorption for most plants.
In addition to their ecological importance, mycelium has gained interest as a food source for humans. Mycelium is nutrient-dense and can be used as a protein biomass for food production. Mycelium-based foods, or "myco-foods", are being explored as an affordable, scalable, and environmentally sustainable new source of high-quality protein for global consumers.

Mycelium is used to make supplements
Mushrooms are a type of fungus with a three-stage life cycle that is similar to the different stages found in plants. Mycelium is the primary stage of the mushroom life cycle and the longest-living part of the organism. It is a dense mass of thread-like filaments typical of filamentous fungal species. These web-like structures spread into the substrate the fungus is growing on, such as wood, soil, compost, coffee, sugar cane, or grains like rice and oats.
The purpose of the mycelium is to find and break down food sources in the substrate and collect nutrients and water for the final creation of the mushroom. Mycelium serves as the immune response that supports the health, vitality, and immune response of the fungal organism, but also supports the health of the surrounding ecosystem. Scientific research, targeted studies, and widespread use in holistic treatment plans demonstrate that when harnessed in the form of supplements, human beings also benefit from the significant health-supporting power of mushroom mycelium.
Supplements made from mycelium may contain varying levels of active compounds like beta-glucans depending on the substrate used. Consumers should review supplement labels to determine whether the product contains the fruiting body, mycelium, or a combination of both. The mushroom (fruiting body) is ideal for manufacturing mushroom supplements because it contains vital nutrients, including proteins, fiber, vitamins, and minerals, and consistently high levels of beta-glucans—immunity boosters. The mushroom has no starch content as the growing substrate is not harvested with it.

Mycelium helps fungi reproduce
Fungi, including mushrooms, play an essential role in the ecosystem. They help recycle nutrients and make them available to other organisms in the environment. Mycelium, a part of the fungal organism, is a dense network of thin filaments called hyphae. Each hypha is surrounded by a robust fungal cell wall that collects food, water, and nutrients to nourish the fungus. This process is similar to the function of roots in plants.
The mycelium helps close the energy cycle of the ecosystem by decomposing organic matter and recycling it into beneficial compounds for the soil food web. Enzymes secreted by these fungal threads facilitate this cycle. The enzymes break down the substrate and the surrounding dead organic matter. The hyphae then facilitate the movement of the nutrients to the mushroom, and recycle the dead plant matter into beneficial organic compounds that are again absorbed by the soil. This process is known as mycoremediation.
The mycelium's role in the decomposition of plant material is vital in terrestrial and aquatic ecosystems. They contribute to the organic fraction of soil, and their growth releases carbon dioxide back into the atmosphere. Mycelial mats have been suggested as potential biological filters, removing chemicals and microorganisms from soil and water. This process, known as mycofiltration, uses fungal mycelium to accomplish the removal of pollutants from the environment.
Mycelium also 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. After fusing, the cells end up in new spores held inside (like in truffles) or exposed outside (like in mushrooms) the fungus' reproductive structures. This is how some fungi reproduce sexually when the environmental conditions are favourable. Fungi can also split their mycelium into smaller fragments, which then form independent mycelial networks.
