Abstract: A method of producing wood-rottening edible mushrooms on a bed prepared from a carbonhydrate, lignin and protein containing compound material, said bed comprising mainly a cellulose containing material, minor amounts of proteinaceous and farinaceous substance as well as water, the bed is packed and pasteurized, a mushroom mycolim is transferred onto bed by injecting, the mycolium is grown in bed by varying the amount of temperature and light, the bed is removed from package for the production of edible mushrooms. According to the invention the bed material is mixed with minor amounts of peat during the preparation of the material, the total amount of starch and protein is restricted to less than 10% and the pH value of bed is adjusted to less than 5.
