The innovative approach uses locally available low cost ingredients for the preparation of the growth medium. The constituent of the medium is formulated as, cow dung 200 g/L, wheat flour 25-30 g/L and agar powder 6 g /L. The content can be sterilized even in pressure cooker if autoclave is not available. The fungus is grown on the surface of the semi solid medium on previously alcohol-washed polythene tray covered with transparent plastic in room condition. The fungus, grown as dark green mat, is homogenized, mixed with talcum powder and packed for use.
