1. A method for preparing a leather analog material comprising fungal biomass, comprising:
(a) size-reducing an inactivated cohesive fungal biomass;
(b) causing an aqueous solution, comprising a solvent, a polymer, and a plasticizer, to infiltrate the size-reduced inactivated fungal biomass to a fungal biomass:polymer loading ratio of between 25:75 and 75:25 by blending the size-reduced inactivated fungal biomass with the solution to form a blended composition;
(c) curing the biomass to remove solvent from the biomass and form the leather analog material, wherein the leather analog material has a tensile strength of at least about 4.5 MPa and a thickness of between about 0.5 mm and about 30 mm; and
(d) adhering a non-fungal textile backing to the biomass.
