PROBLEM TO BE SOLVED: To augment a yield, to uniform growth and development, to save energy consumed and to improve productivity by performing suitable photoirradiation in all processes for hyphal cultivation, fruit-body emergence, and fruit-body growth and development. SOLUTION: When performing hyphal cultivation where mushroom fungi are inoculated into a mushroom-cultivating medium for Lyophyllum, the culture medium is under continuous or intermittent exposure to yellow or red light from a light source having a peak in a wavelength region of 540-720 nm to propagate and ripen hyphae. When making mushroom emerge, the continuous or intermittent irradiation of blue or green light from a light source having a peak in a wavelength region of 300-550 nm is performed, and when growing and developing the mushroom, the continuous or intermittent irradiation of blue or green light in a wavelength region of 300-550 nm is performed.
