How Mushrooms Became The One Ingredient Fixing Fashion, Food, And Packaging

For most of my life, mushrooms were a side dish. Maybe a topping on a pizza, maybe a thing my mother sliced into a curry.

Then I started reading about what scientists were actually doing with the rest of the mushroom, the part you never see on the plate.

What I found surprised me. The fluffy white root network under the cap, called mycelium, is quietly being grown into handbags, shipping foam, leather jackets, and chicken nuggets, often by the same small group of companies.

This is not a trend story about one cool product. It is a slow shift in how three big industries source their raw materials.

The Quiet Material Revolution Most People Are Missing

Mushrooms are not really plants. They sit in their own kingdom of life, closer to animals than to broccoli on the tree of life.

The part we eat is the fruit. The real organism is the mycelium, a dense web of fibers that can grow through wood, straw, sawdust, or agricultural waste in about a week.

That growth speed is the whole story. A cow takes two to three years to become leather. A polystyrene block takes 500 years to break down in a landfill. Mycelium can be grown, harvested, and composted inside a single month.

Once you know that number, every other claim about mushrooms in fashion or food starts to make sense.

How Mycelium Turned Into Leather That Hermès Will Sell

In 2022, Stella McCartney launched the Frayme Mylo, the first luxury handbag sold commercially with mycelium leather instead of cow hide. The material was grown by Bolt Threads inside a vertical farming facility using mulch, air, and water.

Hermès went a different route. The French house partnered with California biotech firm MycoWorks to develop Sylvania, a mycelium-based material used in a version of its iconic Victoria bag. It is the first time a heritage leather house has put a fungus-grown material into one of its signature designs.

Adidas, Lululemon, and Kering, the parent group behind Gucci and Saint Laurent, have also invested in the same supply chain.

The newest entrant is Hydefy, which combines mycelium with sugarcane husk waste and runs the mix through customized vinyl flooring machines. That last detail matters more than it sounds.

Using existing factory equipment is how a niche material scales into something a global brand can actually order in volume.

The Mushroom Foam Replacing Styrofoam In IKEA Boxes

IKEA has been quietly swapping polystyrene foam for a mycelium product called MycoComposite, made by New York company Ecovative.

Workers mix farm waste, things like corn husks and oat hulls, with mushroom spores, then pour the mix into molds shaped like the product being shipped. Within a few days the fungus knits everything into a solid, shock-absorbing block.

Throw it on a compost heap when you are done and it breaks down in roughly 30 to 90 days. Polystyrene, by comparison, can sit in a landfill for centuries.

Dell uses the same packaging to protect its servers. Ecovative now runs a 180,000 square foot facility in Green Island, New York, and reports converting over 10 million pounds of farm waste a year into mushroom material.

There is one honest caveat.

Many industrial composting facilities refuse mycelium packaging because they cannot tell it apart from contaminated waste at scale, which means a lot of it still ends up in regular trash bins. The material itself is benign, but the recycling infrastructure has not caught up.

Why Mycoprotein Is Eating Into The Meat Aisle

The food side is where the numbers get interesting. According to Future Market Insights, the global mycoprotein meat substitute market was valued at around $4.4 billion in 2026, with steady growth projected for the next decade.

Quorn, the British brand that has been making mycoprotein nuggets and mince since the 1980s, is no longer the only player. Meati Foods in Colorado grows whole-cut mycelium steaks and chicken cutlets.

Nature's Fynd uses a fungus originally discovered in a Yellowstone hot spring.

One mid-sized serving of mycoprotein gives you around 11 to 15 grams of protein and 6 grams of fiber. Beef gives you protein but zero fiber, which is the nutritional gap most people on a Western diet are quietly walking around with.

Plenty of familiar grocery items are already plant-based without anyone making a fuss about it. Mycoprotein is sliding into the same category. You can buy it as nuggets, mince, deli slices, and burgers in most large UK supermarkets and a growing number of US ones.

The One Detail That Connects All Three

Here is the thing that took me a while to notice. The mushroom in your packaging, the mushroom in your bag, and the mushroom in your burger are often the same species, or very close cousins, grown in nearly identical fermentation tanks.

What changes is what you feed the mycelium and how you cure the finished sheet.

Feed it sawdust and press it firm, you get foam packaging. Feed it sugarcane husk and tan the surface like hide, you get a handbag.

Feed it sugar in a clean broth and let it knit into long fibers, you get something a butcher could mistake for chicken breast.

Ecovative even calls itself the first new mycelium crop platform in 400 years. That is the part I find genuinely striking.

We are not talking about three different green inventions. We are talking about one organism, finally being used the way it has been used in nature for hundreds of millions of years, which is to break things down and bind things together.

What Still Has To Go Right

None of this is finished. Bolt Threads paused Mylo production in 2023 after running out of funding, and Stella McCartney has since moved on to Hydefy.

Mycelium leather still costs roughly 15 to 25 percent more than animal leather at the luxury tier, and mushroom packaging is held back by the composting problem above.

Mycoprotein has the steadiest path forward of the three, because the supply chain already exists and consumers already eat it.

Fashion will follow when the second or third generation of mycelium materials hit the same price as leather. That is probably five to seven years out, not five months.

A Personal Note On Why This Matters To Me

When I went vegan, the part I worried about most was not the food. It was everything else. The shoes, the wallet, the sofa, the packaging on the cereal box.

Animal products are stitched into the background of almost every object in a Western home, and switching all of them out felt impossible.

What mushrooms are doing, quietly and slowly, is reducing the number of things I have to think about. The cushion inside an IKEA box used to be polystyrene.

The strap on a bag used to be cow. The pieces of chicken in a frozen pie used to be a chicken.

None of that is being marketed loudly. It is just happening, one supplier at a time, in factories most of us will never see.
