    Reishi™ is
    Fine Mycelium™

    Introducing the next evolution in mycelium: Reishi Fine Mycelium, a premium, natural option for leather. 

    Exclusive to MycoWorks, the Fine Mycelium process creates the interlocking, cellular structures that give Reishi its inherent strength and durability. Unlike “mushroom leather” (compressed mycelium) or traditional leather, Reishi is custom-grown to finely tune for fullness and the highest performance standards.

    Fine Mycelium is a breakthrough in materials science and biotechnology, and a platform for new design possibilities.
