Mycelium composites and leathers have versatile material properties based on their composition and manufacturing process. To prepare mycelium mat for the production of mushroom leather, several strains were mutated by gamma rays. Some mutant strains, including Lentinula edodes, Ganoderma lucidium, and Schizophyllum commune showed good hyphae growth rate and density on saw-dust media. Irradiation power (Gy), time, and height from the radiation source to the sample were examined. Based on the preliminary data obtained in this study, comprehensive research should be conducted to explore the optimal strains and culture conditions for mycelium-based leather production.
