Studies were made to optimize the media composition and cultural condition for mycelial growth of Agrocybe cylindracea. Sawdust spawn of media composition for optimal growth was found to be pine sawdust combination of 30% wheat bran and poplar sawdust combination of 20% corn bran were the best of the optimal combination. The optimal concentration of white sugar was 1.0~1.5%. The nitrogen sources was found to be yeast extract and soybean powder. Also, optimal concentration were 0.7g/ℓand 0.1g/ℓ, respectively. The mineral sources of optimal medium compositions were MgSO4·7H2O 0.3g/ℓ, KH2PO4 0.5g/ℓand K2HPO 1.2g/ℓ. Optimal amount of inoculum for cultivation of A. cylindracea were 20~25g/850㎖ and 25㎖/850㎖ in the sawdust spawn and liquid spawn, respectively.
