This experiment was conducts to find out the effects of ceramics mixing on mushrooms mycelial growth and density. It is better ceramics in $800^{circ}C$ than $1000^{circ}C$ to mycelial growth and density of Pleurotus astreatus, Flamulina velutepes, Lentinus edodes and Inonotus obliqua . Mycelial growth according to ceramics mixing contents with mushrooms media is good till 0.16% ceramics mixing, but if mycelial growth and density take into consideration, 0.12% ceramics mixing contents is best.
