Mycoworks’ Mycelium Based Natural Leather

Updated : 14-Oct-2020


Reishi is a biodegradable material that mimics leather, developed using Mycelium (a type of Fungus) that gives the material a versatile leather texture. The fungus is converted into a biomaterial through the patented Fine Mycelium™ process giving the material the strength and structure similar to that of animal leather.

  • Production process has a lower footprint and is sustainable.
  • The company plans to work with brands to create their own Reishi production facilities - to cut transportation emissions.


  • Reishi is a non-animal, non-plastic option for leather - where supple sheets of mycelium can be transformed into sustainable leather that can be tanned, cured, embossed and stitched.

How does this work?

  • Fine Mycelium Process Reishi is grown in trays on plant biomass.  
  • The trays support the company's proprietary fermentation process, enabling mycelium cells to grow in a dense, intertwined structure that produces a strong, uniform sheet.
  • After the sheets are harvested, tannery partners use the proprietary, chrome-free process to produce various finishes, whether that’s the softness or the hand feel or even the stamped texture of different types of animal leathers.
