Mycelium is a viable option in the search for ecologically friendly and sustainable building materials. Mushroom roots provide mycelium, a fungal substance made of fibers resembling roots and the vegetative portion of a fungus. The use of mycelium in constructing materials matches globally set targets concerned with persistence, henceforth offering an eco-friendly, renewable source that is also carbon-neutral, unlike common substances such as cement, plastic, and steel.

Mycelium is a type of fungal material obtained from mushrooms. The fungus fibers make up this fungal substance. It is made of hyphae, which are thin white filaments between which the fungi grow. It is used in construction to grow hyphal strands on organic substrates. The process starts by injecting fungal spores into the substrate, which then develop, spread, and bind together. This mixture is put into molds, and the required shapes and sizes are attained. After the substrate is completely covered with mycelium, it is dried to prevent further growth and to produce long-lasting material; this results in very tough, fireproof, and waterproof fibers from the mushroom root that are also environmentally friendly and decompose easily.

This article explores mycelium’s properties, its construction applications, examples of structures built using this innovative material, and the challenges and prospects.
