A method of cultivating shiitake mushroom(oak mushroom, Lentinus edodes) and white shiitake mushroom using a medium or soaking liquid containing selenium and aspartic acid to induce accumulation of the selenium is provided, which cultivates shiitake mushroom having high contents of selenium, provides optimal temperature and humidity conditions for inducing white shiitake mushroom and recycles used medium. The shiitake mushroom is cultivated by the steps of: culturing spawn in a liquid medium for 2 to 3 days; adding 0.01 to 0.05ppm selenite solutions and 5 to 10ppm aspartic acid to the liquid medium and performing spawn culturing; inoculating spawn cultures into a solid medium containing 0.01 to 0.05ppm selenium and 5 to 10ppm aspartic acid and culturing until the diameter of mushroom cap reaches 2 to 4cm; and soaking the solid medium remaining after harvesting in soaking liquid containing 0.05 to 0.1ppm inorganic selenium and 10 to 20ppm aspartic acid for 16 to 24hr to give a medium with a moisture content of at least 75%. The medium is recycled 1 to 7 times. The white shiitake mushroom is cultivated by the steps of: cultivating shiitake mushroom with a cap size of 2 to 4cm while maintaining the internal temperature and humidity at 10±3deg.C and 75±5%; quickly changing the internal temperature and humidity to 35 to 40deg.C and 35 to 40% for 2 to 4hr using hot air to induce separation of the cap surface; quickly reducing to 5 to 10deg.C and 70 to 80%; and continuing the above step 1 to 3 times per day for 7 days to cause a change in color from brown to white.
