Mycelium is a fascinating part of fungi, often referred to as the roots, with mushrooms being the fruit. It is a network of thread-like membranes that grows under the soil or on other substrates, forming vast networks. Mycelium plays a crucial role in fungal reproduction and survival, as it fuses with other compatible fungi, allowing their DNA to mix and creating new spores. It also breaks down organic matter, providing food for the fungi and other organisms, and can form unique relationships with plants, exchanging nutrients and increasing their resilience. Mycelium has recently gained attention for its potential environmental applications, such as creating sustainable alternatives to leather and plastic.

What You'll Learn
Mycelium is the vegetative body of a fungus
Mycelium is a network of thread-like roots that form the vegetative body of a fungus. It is often compared to the roots of a plant, but it is quite different. Mycelium is usually hidden from sight, lurking underneath the soil or on other substrates like rotting logs. It forms vast networks that can be invisible to the naked eye or as large as 10 square kilometres.
Mycelium is responsible for secreting enzymes that break down complex organic molecules from things like branches, leaves, dead bugs, and animals into digestible nutrients that it can then absorb and use to grow. This process of breaking down organic matter is critical for maintaining healthy soil, recycling leaf litter, and providing food for the bacteria and animals that live in the soil.
Mycelium also plays a crucial role in fungal reproduction. When two compatible fungi meet, their mycelia can fuse together, allowing their cells and DNA to combine and form new spores. These spores can then be transported by wind or animals, leading to the growth of new fungi.
In addition to its role in reproduction, mycelium is also essential for the survival of fungi. Fungi cannot move around and hunt, nor can they derive energy directly from the sun like plants. Instead, they must spend energy to get energy. Mycelium accomplishes this by forming unique relationships with plants, exchanging nutrients for carbohydrates. This connectivity is a powerful tool for the survival of both fungi and plants, as it increases their resilience to infestation and disease.
Beyond their ecological significance, mycelial networks have practical applications. They can be used to create biodegradable materials, such as textiles, meats, and fashion products. Additionally, mycelium can be used to create artificial leather. This leather alternative is cheaper to produce, has a lower environmental impact, and is biodegradable, offering a promising solution to the resource-intensive traditional and synthetic leather industries.

Mycelium is to mushrooms as roots are to plants
Mycelium is a network of thread-like membranes that forms the vegetative body of a fungus. It is often referred to as the "'roots'" of a fungus, just as roots are to plants. This network is responsible for secreting enzymes that break down complex organic molecules, such as branches, leaves, and dead animals, into digestible nutrients that the mycelium can then absorb and use for growth. This process of decomposition is vital for maintaining healthy soil and providing food for bacteria and soil-dwelling animals.
While mycelium is indeed the "roots" of a fungus, it is not limited to this function. It is more accurately described as the roots, trunk, branches, and leaves of a fungus, with mushrooms being the fruit. Mycelium is the part of the fungus that does all the work, forming vast networks that can cover up to 10 square kilometres. These networks are hidden underneath the soil or on other substrates, such as rotting logs, and are responsible for the fruiting bodies of fungi, which we know as mushrooms.
Mushrooms are the reproductive structures of fungi, and they produce spores that start the cycle anew. These spores are tiny, seed-like structures that are transported by wind or animals. The mycelium can also be separated from the origin body and grow a new network through hyphal separation, a process known as "propagation" in plants. This process allows for the transfer of mushrooms to a different "host" without the use of spores.
Just as mycelium is essential for fungi, roots are vital for plants. Roots absorb water and nutrients from the soil, and in return, plants supply the roots with energy in the form of carbohydrates. This exchange of resources creates a mutually beneficial relationship between the two organisms.
In summary, mycelium to mushrooms is as roots are to plants. Both mycelium and roots form a network that provides a crucial function for the survival and growth of their respective organisms. They are the interface between the organism and its environment, absorbing nutrients and exchanging resources to foster collective growth within their ecosystems.

Mycelium is used to create artificial leather
Mycelium is the root-like part of a fungus, similar to the roots, trunk, branches, and leaves of a plant. Mushrooms are the fruit of the fungus, and mycelium is necessary for mushrooms to grow. Mycelium plays a crucial role in fungal reproduction, as the mycelia of two compatible fungi can fuse together, allowing the cells of each fungus to combine and their DNA to mix. This is how some fungi reproduce.
Mylo is a vegan and sustainable alternative to animal leather. It is soft, supple, and less harmful to the environment. Unlike leather production, which involves raising livestock and contributes to deforestation and greenhouse gas emissions, Mylo does not involve the use of animals and is grown using 100% renewable energy. Additionally, the processing of animal hides into leather generates a large amount of toxic chemicals, which are released into the environment. Mylo is also cheaper to produce than animal leather, with a lower environmental footprint, and is biodegradable.
However, one challenge with Mylo is that it is not currently biodegradable, and the use of polymeric materials to improve the properties of artificial leather can negatively affect its biodegradability. Additionally, Mylo is not plastic-free, as the use of materials like polyester or polylactic acid can improve the durability and flexibility of the product. Nevertheless, companies like Bolt Threads are working towards creating more sustainable versions of Mylo that can be repurposed and reused, reducing the environmental impact of the material.

Mycelium can be used for mycofiltration
Mycelium is a root-like structure of a fungus, consisting of a mass of branching, thread-like fibres called hyphae. It is the body of the fungus, while the mushrooms are the fruit. Mycelium can be separated from the origin body and grow a new network, a process known as hyphal separation. Mushrooms cannot grow without the mycelial network they fruit from.
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. After fusing, the cells end up in new spores held inside (like in truffles) or exposed outside (like in mushrooms and crusts) the fungus' reproductive structures. This is how some fungi reproduce and form spores.
Mycelium is vital in terrestrial and aquatic ecosystems for its role in the decomposition of plant material. It contributes to the organic fraction of soil, and its growth releases carbon dioxide back into the atmosphere. Mycelium is an important food source for many soil invertebrates and is vital to agriculture and almost all species of plants.
Mycofiltration involves passing contaminated water through a network of saprophytic fungal mycelium. It has been used to remove Escherichia coli from synthetic stormwater. It is also a potential method for treating drinking water sources.

Mycelium is a solution to environmental problems
Mycelium is a root-like structure of a fungus, consisting of a mass of branching, thread-like, and entangled filaments called hyphae. It is often referred to as the "body" of the fungus, with mushrooms being the "fruit". Mycelium plays a crucial role in fungal reproduction and is vital in ecosystems for its ability to decompose organic compounds, including pollutants like petroleum products and pesticides. This process, known as mycoremediation, has the potential to eradicate these pollutants from the environment.
Mycelium's ability to decompose organic matter is essential for maintaining healthy soil and providing food for soil organisms. It contributes to the organic fraction of soil and increases the efficiency of water and nutrient absorption for plants, even conferring resistance to some plant pathogens. Mycelium can also form symbiotic relationships with plant roots, creating a cross-kingdom network known as mycorrhizae, which further enhances the health and growth of plants.
In addition to its ecological significance, mycelium offers solutions to environmental problems caused by human activities. Mycelium-based products, such as artificial leather, packaging, clothing, and construction materials, provide more sustainable alternatives to conventional practices. For example, the production of animal leather contributes to deforestation, greenhouse gas emissions, and grazing issues. In contrast, fungal-based leather is cheaper, has a lower environmental impact, and is biodegradable.
Mycelium's fast-growing fibres can also be used to create meat-like structures, providing a cruelty-free alternative to traditional livestock farming, which reduces greenhouse gas emissions and land use. Furthermore, mycelium can be utilised in mycofiltration, where mycelial mats act as biological filters, removing chemicals and microorganisms from soil and water.
The versatility and adaptability of mycelium present exciting opportunities for innovation and environmental remediation. By harnessing the power of mycelium, we can develop sustainable solutions that benefit our planet and promote harmony with nature.
