Provided is a method for culturing a fungus, which enables a mycelium of a basidiomycete to be grown into a fruiting body in a solid culture medium or a liquid culture medium and therefore can culture the basidiomycete with uniform quality, with high efficiency and in a simple manner. The method for culturing a fungus comprises: a mycelium proliferation step [I] for forming a reinforcing body (15) selected from a mesh, a woven fabric, a non-woven fabric and a porous sheet using a metal, a synthetic resin, a natural resin and/or paper, applying a basidiomycetous mycelium culture medium (14) onto the reinforcing body (15), then inoculating a mycelium of a basidiomycete (20) onto the front surface side of the reinforcing body (15) by coating or spraying a culture liquid (17) of the mycelium onto the front surface side to form a sheet (1) for mycelium-growing/culturing purposes, and then growing the mycelium and a fruiting body proliferation step [II] for applying a basidiomycetous fruit body culture medium (24) to the mycelium that has been grown on the front surface side to form a sheet (2) for fruit body-growing/culturing purposes and then allowing the mycelium to be grown into a fruiting body.担子菌類を、固体培地又は液体培地で菌糸体から子実体に、育成して、均一な品質で効率良く、簡便に培養できる菌類培養方法を提供する。 菌類培養方法は、金属、合成樹脂、天然樹脂、及び/又は紙で、メッシュ、織布、不織布、多孔質シートから選ばれる補強体15を形成し、担子菌類菌糸体用培地14を付してから、それのおもて面側に担子菌類20の菌糸体をそれの培養液17の塗工又は噴霧により接種し、菌糸体育成培養シート1を形成した後、前記菌糸体を育成する菌糸体増殖工程[I]と、前記おもて面側で育成した前記菌糸体に、担子菌類子実体用培地24を付して、子実体育成培養シート2を形成した後、前記菌糸体から子実体へ育成する子実体増殖工程[II]とを、有する。
