A Fungus Among Us
Fungi are important right now — not just for food or health, but also in advanced labs and fashion workshops. One exciting new idea is mushroom leather, also called mycelium leather. Some innovators even begin the process in controlled setups like a Mushroom Grow Bag or a Monotub before scaling it for material production. This sustainable leather alternative could transform many products, from bags to car interiors. Here, you’ll learn what makes mushroom leather so promising, how it’s made, and why many people see fungi as the future of fashion.
What Is Mushroom Leather?
Mushroom leather is a plant-based leather option made from mycelium. Mycelium is the branching, thread-like root structure of fungi. This underground network works like plant roots, but it is special to fungi. Mycelium is the network that breaks down organic material in forests and fields, not the edible part of a mushroom.
Mycelium leather is special because it is grown, not from animals or made chemically. Traditional leather comes from livestock. Synthetic PU/PVC leather comes from fossil fuels. But mycelium leather is a plant-based choice. It is a strong, animal-free material with a small environmental impact. Also, it looks and feels like real leather.
Mushroom leather can look like soft suede or tough, flexible hide. This depends on how it is grown and processed. This makes it good for many uses. Its ability to change, and its good environmental and ethical points, make it a leading material for sustainable leather.
How Is Mushroom Leather Made?
Making mushroom leather is quite simple and good for the environment.
-
Feeding the Mycelium: The process starts with agricultural waste. This includes sawdust, corn husks, hemp stalks, or other plant material. This waste gives mycelium food to grow.
-
Controlled Growth: Mycelium grows quickly over a mold or flat surface. It forms a thick mat. This happens under controlled humidity, temperature, and carbon dioxide levels. This “fabric” typically becomes thick enough to harvest in just two to three weeks.
-
Harvesting and Treatment: The mat is harvested when it reaches the right thickness and size. Then, it is pressed flat, dried, and treated to make it strong, give it a certain feel, and color it.
-
Finishing Touches: Finishing usually involves natural tanning. This uses plant-based oils, dyes that are not toxic, or waxes that are sustainable. Some companies may add thin layers to fabrics. This makes the material stronger or more water-resistant.
This process is special because it is a circular process. Agricultural waste becomes animal-free leather using little energy and water. It does not need grazing land, cows that make methane, or tanning vats full of chemicals. And because this whole process can happen indoors, it is less affected by weather changes or worries about land use.
The Sustainability Case: Why Mycelium Leather Matters
The traditional leather industry is one of the most polluting industries in fashion. It also uses a lot of resources. Here is a look at what this means:
Environmental Impact of Traditional Leather:
- It causes about 14.5% of all global greenhouse gas emissions (FAO, 2017). Cattle raising is the main reason for this.
- It causes more deforestation, especially in places like the Amazon, to make land for grazing.
- It needs huge amounts of water. One leather bag can use thousands of liters to make.
- It uses a lot of toxic tanning chemicals like chromium. These pollute rivers and underground water, harming wildlife and people.
In Contrast, Mycelium Leather:
- It grows on renewable agricultural waste. This makes a new source of income from things that would otherwise be waste.
- It uses only a small amount of water because it grows indoors in controlled settings.
- It does not use toxic tanning chemicals. Instead, it uses safer, natural ones.
- It greatly reduces carbon emissions, with some processes being almost carbon-neutral (Holt et al., 2021).
Early studies show that mycelium leather could be better than other plant-based leathers (like Piñatex or cork). It uses less water and creates fewer emissions. This makes it a top material for sustainable leather.
Ethical & Safe: Supporting Cruelty-Free and Toxic-Free Fashion
More and more buyers want materials that fit their beliefs. Mycelium leather meets many ethical points:
Animal Welfare
Mushroom leather completely removes the need to raise or kill animals. This takes away worries about:
- Factory farming
- Animal stress
- Unkind treatment
- Slaughterhouse conditions
It is 100% vegan. So, it is good for brands and buyers who care about animal rights.
Worker Safety
Tanning with chromium salts is common in traditional leather making. But it is a big risk for workers. Getting too much hexavalent chromium has been linked to cancer, skin problems, and breathing issues.
Mycelium leather production does not use these chemicals. This makes it safer for the environment and for the workers.
Consumer Health
Coatings that are not toxic mean fewer things that cause allergies and less chemical release. Buyers who care about their health and clean living can feel good about wearing or using mycelium items close to their body.
Is Mushroom Leather Durable Enough?
How long it lasts is a natural worry, especially for fashion, shoes, and furniture. Early types of mushroom leather were not as strong as animal leather. This was especially true for those without a finish or extra strength.
But new developments have made the quality much better. Mycelium leather can now:
- Resist scuffing and tearing
- Hold stitching like animal leather
- Be made water-resistant with plant-based treatments
- Do well in wear tests when it is finished properly
Lab results from Holt et al. (2021) show that treated mycelium materials can be as strong as natural leathers and very flexible. For fashion, it is good enough. But some special uses, like protective gear or strong furniture covers, might still need extra strength.
With the right layers, composite layering, or extra strength from natural fabrics like hemp or cotton, mushroom leather is lasting just as long.
Common Properties of Mycelium Leather
Knowing the qualities of mushroom leather helps show why it is useful.
- 🧵 Texture: It is naturally soft and flexible, often feeling like suede.
- 🧊 Breathability: It lets air flow well because it has tiny holes. This makes it comfortable.
- 🌿 Biodegradability: It breaks down naturally in compost if it is not mixed with man-made materials.
- 💦 Water Resistance: It resists moisture when treated, but it is not waterproof on its own.
- 🔥 Lightweight: It is easier to use and wear for clothes, bags, and accessories.
- 💡 Customizable: It can be grown into certain shapes and textures. This means less waste from cutting and sewing.
This makes it very appealing to fashion companies. For them, comfort, usability, and environmental benefits must all work together.
Who’s Making Mushroom Leather?
Several companies are leading the field with new ideas:
🧪 MycoWorks
MycoWorks, based in California, uses a special Fine Mycelium™ process to make Reishi™. This is a high-quality leather option that luxury designers like. Their science method gives them new control over how it feels and how long it lasts. This opens the door for very high-end uses.
🧵 Bolt Threads
Bolt Threads makes Mylo™, a flexible material from mycelium grown in vertical farms. They work with big names in fashion, like Stella McCartney, Lululemon, and Adidas. With big investments and important business deals, Bolt Threads wants to bring mycelium leather to everyday fashion.

Mushroom Leather vs. Animal Leather
| Feature | Animal Leather | Mushroom Leather |
|---|---|---|
| Time to Produce | Up to 2+ years (including animal rearing) | ~2–3 weeks (Holt et al., 2021) |
| Water Use | Very high | Very low |
| Toxic Chemicals | Often used in tanning | None or very little |
| Carbon Emissions | High (14.5% of GHGs) | Low to potentially negative |
| Animal Impact | Big ethical worries | Animal-free |
| Cost (currently) | Moderate to high | Similar to expensive leather |
| Biodegradability | Low (for treated hides) | High (unless man-made coating is used) |
This comparison shows that mycelium leather has clear benefits for sustainability, health, and ethics. And it does not lose quality.
Is Cost a Barrier?
Mycelium leather is expensive now. It costs about as much as high-end designer leather. But this is normal. New materials often cost more at first because of:
- Research and development costs
- Small batch or lab production
- Not enough big factory machines
But experts in the field think prices will go down over the next five to ten years. This will happen as:
- Production places grow
- Demand goes up
- Ways of making it become standard and better
- Making more of it makes it cheaper
Buyers are already pushing designer brands to use fungi-based products. More interest will likely keep making prices equal, especially as environmental rules become stricter.
How Does Mushroom Leather Stack Up Against Other Alternatives?
Several other leathers are being made or are already for sale. How does mycelium leather compare?
| Material | Source | Water Use | Time to Produce | Biodegradable | How much can be made | How long it lasts |
|---|---|---|---|---|---|---|
| Mycelium Leather | Fungi/mycelium | Low | 2–3 weeks | Yes | High | High |
| Piñatex® | Pineapple leaves | Moderate | Months (seasonal) | In part | Medium | High |
| Apple Leather | Apple waste | Moderate | Only at certain times of year | In part | Low | Moderate |
| Cactus Leather | Cactus pulp | Low | Months (seasonal) | In part | Medium | Moderate |
| PU (Synthetic) | Petroleum | High | Fast | No | Very high | Very high |
Mushroom leather is different mainly because it can grow indoors. It is available all year and does not rely much on seasonal plants.
Beyond Fashion: Future Mycelium Applications
Mushroom leather is not just for handbags. Its flexibility, sustainability, and look make it good for wider design and industrial uses. This includes:
- Furniture & Interior Design: Homes and offices that care about the environment can use it for covers, cushions, and decoration.
- Automotive Industry: Car makers are looking into mycelium covers as a vegan and fancy choice instead of leather inside cars.
- Packaging Solutions: Using fungal solutions instead of polystyrene foams gives packaging that breaks down naturally for electronics and delicate items.
- Shoes and Accessories: Mycelium leather is good for fashion stores, from wallets to belts.
- Architecture & Art: Art projects are already using panels and tiles made from shaped mycelium.
The more industries that use the material, the faster costs will go down as more is made.
