For centuries, Ganoderma lucidum—commonly known as Reishi or Lingzhi—has been valued in East Asian traditional biotechnology. Today, this fungus is attracting attention for another reason: its mycelium is being studied as a source of bio-based materials.

Mycelium is the underground network of a fungus, made up of interconnected microscopic filaments. When fungi grow through substrates such as sawdust, straw, or other plant-based biomass, the mycelial network can bind the material together into lightweight composites.

Research has shown that the properties of these materials depend on many factors, including fungal species, substrate, growing conditions, density, and processing methods. Studies involving Ganoderma lucidum have demonstrated that different growth substrates can influence the chemical composition and mechanical performance of the resulting materials.

However, Reishi is not the only fungus used in this field. Mycelium-based materials are being developed using multiple fungal species, and research results cannot automatically be attributed to G. lucidum alone.

Commercial Progress: Mycelium-Based Leather Alternatives 

One of the clearest examples of mycelium moving from research toward commercial use is in leather alternatives.

MycoWorks has developed Fine Mycelium™, a proprietary technology for producing mycelium-based materials, and commercialized its Reishi™ material for applications including fashion and design.

A documented collaboration between MycoWorks and Hermès resulted in Sylvania, a Fine Mycelium material used in a version of the Victoria bag. This demonstrated that a material grown from fungal mycelium could enter the luxury-goods supply chain.

However, mycelium materials should not yet be considered full replacements for conventional leather. Performance depends on the specific manufacturing process, formulation, and finishing methods.

Packaging and Composite Materials

Mycelium composites are also being investigated for protective packaging and lightweight material applications.

The basic process involves allowing fungi to grow through organic substrates, where the mycelium binds particles together into a shaped structure. After processing, the resulting material can provide lightweight, molded forms with potential biodegradability.

Research suggests that mycelium composites could serve as alternatives to some petroleum-based foams. However, their performance varies significantly depending on fungal species, substrate, and production methods. Strength, moisture resistance, and degradation rates must be evaluated for each specific application.

Construction and Acoustic Applications

Researchers are also exploring mycelium composites for insulation, acoustic panels, and other non-structural building applications.

Studies using Ganoderma lucidum and other fungi have shown that mycelium-based materials can exhibit useful thermal and acoustic properties. A 2024 study examining wheat-straw-based composites produced with G. lucidum and Pleurotus ostreatus found that fungal species and cultivation conditions influenced material performance.

These results suggest potential applications in lightweight building materials, but significant challenges remain, including moisture sensitivity, long-term durability, manufacturing consistency, and large-scale production.

Biological Research: A Future Possibility

Fungal mycelium is also being investigated in materials engineering because its natural three-dimensional network resembles certain structures used in tissue scaffolds.

A 2021 study published in Scientific Reports examined fungal mycelia, including Ganoderma lucidum, as potential biomaterials for tissue engineering. The research explored their structure, mechanical properties, and interaction with human cells.

These findings are promising, but the technology remains experimental. Reishi mycelium is not currently a validated structural material, structural repair material, or biotechnological dressing. More research is required before human scientific applications can be considered.

A Promising Technology, Not a Finished Solution

The appeal of fungal biomaterials lies in a different approach to manufacturing: using biological growth to help create materials from renewable resources such as agricultural residues and plant-based waste.

However, bio-based does not automatically mean environmentally superior. Energy use, processing requirements, durability, transportation, and end-of-life management all influence the true environmental impact of a material.

The current evidence suggests that Ganoderma lucidum is a meaningful contributor to the growing field of fungal biomaterials. Its mycelium has demonstrated potential in areas ranging from leather alternatives to insulation and biotechnological research.

The future of these materials is not about fungi replacing every conventional material. Instead, it is about exploring a new manufacturing model—one in which some materials are not only produced, but grown.

The technology has already moved beyond scientific curiosity into early commercial applications. How far it can scale will depend on continued advances in performance, cost, durability, and environmental assessment.
