[...] This magic biomaterial is mycelium, the vegetative part of the fungus. If you imagine that mushrooms are the 'fruits' of the fungus, mycelium could be regarded as its roots or stems. It looks like a mass of white thread-like structures, each called hyphae, which crisscross soil and other material in which fungi grows. Collectively, these threads are called mycelium and are the largest part of the fungus.

Mycelium has amazing properties. It is a great recycler, as it feeds off a substrate (like sawdust or agricultural waste) to create more material, and has the potential of almost limitless growth in the right conditions. It can endure more pressure than conventional concrete without breaking, is a known insulator and fire-retardant and could even provide radiation protection on space missions.

On Earth it's currently used to create ceiling panels, leather, packaging materials and building materials, but in outer space it stands out for its architectural potential, says artist and engineer Maurizio Montalti, who has teamed up with Ciokajlo.
