PROBLEM TO BE SOLVED: To provide an indoor artificial cultivation method for generating Leucopaxillus giganteus with high quality every year continuously and stably.SOLUTION: A plurality of mushroom beds of subdivided Leucopaxillus giganteus is mixed or contacted and they are with materials for embedding fungus in the container. A mycelial pellet is arranged away from at least one face of a container inner wall by a given distance in view of the upper surface of the container. The atmosphere in the container is maintained below 20°C, and the spawn is grown. Then, after maintaining the atmosphere at a higher temperature than the temperature at which the spawn was grown, the atmosphere in the container is maintained in below 20°C again.COPYRIGHT: (C)2016,JPO&INPIT【課題】オオイチョウタケを発生させる屋内人工栽培方法において、毎年、安定的に継続して、高品質のオオイチョウタケを発生させる。【解決手段】オオイチョウタケの小分けした複数の菌床を混合または接触させて容器内に菌埋め込み用資材と共に、容器を上面からみて、容器内壁面の少なくとも一面から所定の距離を離して菌糸塊を配置して、容器を20℃未満の雰囲気に保持して菌糸を成長させ、その後菌糸を成長させた温度よりも高温の雰囲気に保持した後に、再度20℃未満の雰囲気に容器を保持する。【選択図】図1
