Fungi make up a vast group of organisms comprising some 100,000 species among which we find both the well-known edible and poisonous mushrooms and also the microscopic species which constitute the majority. According to the traditional classification of living organisms into the animal and vegetable kingdoms, fungi used to be placed with the plants. Gaining currency at present, however, is the view of fungi as an independent kingdom of organisms fundamentally differing both from plants and animals (L. L. Velikanov et al., 1981).
