Ganoderma lucidum is a fungus with an edible fruiting body. This fungus had a very good medicinal effect rather than a nutritional effect. On the field, I understand that no textbooks on monographs on Ganoderma lucidum. Hence I intended to prepare a book on A monograph on the biology of Ganoderma lucidum. This book covers almost all aspects of Ganoderma lucidum i.e., taxonomy, structure, cultivation, chemical constituents, and biological effects with reference to antioxidant, anticancer and antimicrobial potentials. This book is prepared for the benefit of undergraduate, postgraduate and research students.
