“…Mushrooms are edible fungi whose food value lies between meat and vegetables (Bano, ). Besides nutritional, mushrooms have medicinal importance (Bilal et al ., ) and have been used in health care for treating skin diseases (Breene, ; Gunde‐Cimmerman, ), tumours (Ikekawa et al ., ), epilepsy, wounds, heart ailments, rheumatoid arthritis, and have been used as vermicides (Bahl, ).
