Mushroom Spawn, commonly known as Button Mushroom Spawn, is a fungal propagation material used for cultivating mushrooms in controlled growing environments. Spawn consists of mycelium grown on a sterile carrier such as grain or organic substrate, which allows the fungus to colonize the growing medium and produce fruiting bodies. Button mushrooms develop small rounded caps with short stems and grow best in compost-based substrates under moderate temperatures and high humidity. Mushroom cultivation is typically carried out indoors or in shaded areas where moisture, ventilation, and temperature can be managed.
