PROBLEM TO BE SOLVED: To provide a short-term cultivation method of Pleurotus nebrodensis (Bailinggu in Chinese) and an efficient resource-saving cultivation method of Pleurotus nebrodensis. SOLUTION: This short-term cultivation method of Pleurotus nebrodensis comprises, in mushroom bed cultivation of Pleurotus nebrodensis, transplanting mature mycelia brought to a mature condition by separately culturing and low temperature treating, onto the surface of a mushroom bed comprising spread mycelia in a spreading condition in a cultivation container by inoculating spawn followed by culturing, and connecting both the mycelia to each other to sprout and raise carpophores. Alternatively, the cultivation method of Pleurotus nebrodensis comprises, in mushroom bed cultivation of Pleurotus nebrodensis, transplanting infant carpophores formed by other culture onto the surface of a mushroom bed comprising mature mycelia obtained by inoculating spawn followed by culturing and low temperature treating so as to raise the infant carpophores.
