FIELD: mushroom growing. SUBSTANCE: method involves preparing reactive mixture containing aqueous solution of polyvinyl alcohol and aqueous solution of nonionogenic surfactant and joining agent (carbamide, glyoxal); foaming mixture to increase volume by 2.5-3 times; introducing acetilation reaction catalyst; introducing cellulose textile wastes, such as flax scutch and/or cotton scutch, into foamed pulp; pouring obtained composition into molds; conditioning while providing heating; washing till pH value reaches neutral level and washing water is free from joining agent traces. Washed composition is impregnated with nutritive solution and contains glucose, peptone, KH₂PO₄,K₂HPO₄,MgSO₄,CuSO₄,FeSO₄•7H₂O,CaCl₂. EFFECT: simplified method and increased mushroom yield. 3 cl, 2 tbl
