Abstract

A mycological biopolymer product consisting entirely of fungal mycelium is made by inoculating a nutritive substrate with a selected fungus in a sealed environment except for a void space, which space is subsequently filled with a network of undifferentiated fungal mycelium. The environmental conditions for producing the mycological biopolymer product, i.e. a high carbon dioxide (CO₂) content (from 5% to 7% by volume) and an elevated temperature (from 85° F. to 95° F.), prevent full differentiation of the fungus into a mushroom. There are no stipe, cap, or spores produced. The biopolymer product grows into the void space of the tool, filling the space with an undifferentiated mycelium chitin-polymer, which is subsequently extracted from the substrate and dried.
