MycoWorks' Fine Mycelium leather is trademarked
MycoWorks Fine Mycelium leather is indeed trademarked. The company was founded in 2013 by Sophia Wang and Philip Ross, who aimed to commercialize the "mycotecture" technique—the creation of materials from the manipulation of mycelium, the substance comprising the root structure of mushrooms.
MycoWorks supplies its trademarked Fine Mycelium "leather" to big-name companies such as Hermès and Cadillac. The material has the look and feel of leather but is free of animal parts. It is created by combining mycelium with waste from sawmills in trays. As the sawdust decomposes, the mixture develops into a thin sheet, which can then be customized to meet specific textures and colors.
The process of making mushroom leather typically involves cultivating and harvesting the mycelium, which then gets treated with various chemicals and dyes. The closed tray system designed by MycoWorks' co-founders has helped overcome the inconsistencies brought about by the natural, uncontrolled growth process of mycelium, making it a suitable alternative for the apparel and footwear industry.
MycoWorks' Fine Mycelium leather is a groundbreaking innovation that has attracted interest from big-name companies and is poised to disrupt the leather goods market, which was valued at over $400 billion in 2021 and is expected to surpass $720 billion by 2030.

MycoWorks' Reishi is a leading contender as a leather replacement
MycoWorks Reishi is a leading contender as a leather replacement. Reishi is a material designed to evoke the same confidence and emotion that animal leathers do, while showcasing an increase in strength, durability, and hand feel in comparison to similar materials in the marketplace. The material is made from mycelium, the vegetative part of a fungus, and is grown in a substrate of agricultural waste, such as corn husks or sawdust.
The process of creating Reishi involves combining mycelium with waste from sawmills in trays. As the sawdust decomposes, the mixture develops into a thin sheet. The material can then be customized to meet clients' specifications, including specific textures, and can include the addition of other fibers, like cotton. The Fine Mycelium, the trademarked name for its patented technology, is then finished by outside tanneries without the use of chromium, a historically polluting part of leather manufacturing.
Reishi is currently being rendered in several different types of leather goods such as sneakers, boots, ready-to-wear, bags, and wallets. The material has gained some traction in A-list circles, with celebrities such as Natalie Portman and John Legend participating in the investment round alongside several major fashion brands. One client that has already incorporated Reishi is the fashion house Hermès, which styles and tans the fabric (which it calls Sylvania) to use in its Victoria handbags. Nick Fouquet, a designer hatmaker based in Venice, California, who is popular among celebrities, also used Reishi in some of his hats this year.
MycoWorks has enormous potential in the leather goods market, which exceeded $400 billion in 2021 and is expected to surpass $720 billion by 2030. The company has obtained more than 75 patents and now has over 160 employees in the United States, France, and Spain. It has also secured collaborations with high-end companies like Hermès and, most recently, the furniture maker Ligne Roset and GM Ventures, the investment arm of General Motors.
