Abstract: An abrasion resistant finish for a fungal material, the finishing comprising an optimum quantity biodegradable polylactic acid plastic (PLA) dispersed in water to produce a PLA mixture. When the PLA mixture is applied to the fungal material, water carries the PLA deeply into the matrix of the fungal hyphae to a depth at least 2 N/10 mm or 1% of the thickness of the fungal material, whichever is greater. The finish fortifies the hyphal structure as the water evaporates and creates a PLA coating on the fungal material with improved abrasion resistance and water resistance.

Abstract: A mycelium growth bed for optimal production of pure mycelium or a pure mycelium composite with controlled or predictable properties, the bed comprising a tray, a conveying platform, a permeable membrane, a substrate, a porous material and a lid. The permeable membrane is positioned on the conveying platform within the tray. The substrate is positioned on the permeable membrane and the porous material is positioned on top of the substrate. The system provides a configuration having a substrate weight to surrounding space volume ratio between 0.5 and 5.0 g/cc, an air volume (surrounding space) to substrate volume between 0.01 and 1.0, and an air volume (surrounding space) to substrate area is between 0.5 and 5 cc/cm, wherein the CO2 concentration is held above 3%, the relative humidity is held above 40% and the O2 concentration is held below 20% in steady state conditions to produce leather-like mycelium without fruiting bodies.

Abstract: A method for reducing and determining coefficient of friction of a mycelium for improving a plurality of mechanical properties of the mycelium. In the method, a first mycelium layer is contacted with an abrasive and pressure apparatus for smoothing and altering a microstructure of the mycelium. The smoothing of the mycelium microstructure reduces the coefficient of friction of the mycelium thereby enhancing the abrasion resistance of the mycelium. The coefficient of friction of the mycelium surface reduced through smoothing of the mycelium surface is determined utilizing a tilt angle mechanism.

Abstract: A flexible fungal composite with an engineered and/or improved mechanical properties such as tear strength, tensile strength and resistance to separation. The fungal composite is generated by embedding a second material within a fungal matrix. The tear strength of the fungal composite is greater than the tear strength of the fungal matrix. The tensile strength of the fungal composite is at least equal to the tensile strength of the embedded material. And the resistance to delamination between the fungal matrix and the embedded material is such that the force required to separate the fungal matrix and the embedded material from each other is greater than or equal to the force required to separate the fungal matrix or the embedded material from themselves.

Abstract: Fungal crosslinked structures, fungal crosslinking systems, and methods for crosslinking a fungal material. The crosslinked fungal material described herein comprises a variety of crosslinkers, crosslinking sites, and various combinations of crosslinks, each forming unique structures. The crosslinked fungal material comprises at least one crosslinking compound attached to a bonding site. The fungal crosslinking system includes a preparation unit, an impregnating unit, a crosslinking unit and a rinsing unit. The preparation unit may partially deacetylate chitin within the fungal material and within chitin nanowhiskers. The impregnating unit impregnates the fungal material with chitin nanowhiskers. The crosslinking unit is configured to crosslink the fungal material and chitin nanowhiskers via genipin to create a composite material. The rinsing unit rinses and removes unreacted genipin material thereby rendering a crosslinked composite material.

Abstract: A fungal growth structure comprising a nutritive vehicle, a porous material, an administrable space. fungal tissue comprising fungal hyphae having a growth pattern, the fungal tissue connecting said nutritive vehicle to said porous material to said administrable space, wherein the fungal tissue within said space defines at least one successive fungal material layer; and a chemically or physically altered separated portion of fungal material, the separated portion separated from said fungal tissue.

Abstract: A method of forming fungal materials and fungal objects from those fungal materials, the method comprising the steps of growing a first fungal tissue in contact with a nutritive vehicle; supplying a porous material in contact with said first fungal tissue; directing growth of said fungal tissue through said porous material such that a portion of said fungal tissue comprises a first fungal material having first fungal hyphae; optionally incorporating composite material; directing a change in the composition or growth pattern of at least some of said first fungal hyphae; separating at least a portion of the first fungal material from said nutritive vehicle; obtaining a second fungal material having second fungal hyphae; and forming a fungal object by encouraging fused growth between said first fungal material and said second fungal material and optionally incorporating composite material.
