Abstract Introduction Historical Review Soil fungal flora The abundance and physiological activity of the fungal flora of ditl’erent habitates vary considerably. and the community and its biochemical activities undergo appreciable fluctuation with time at any single site. Both the generic composition and the size of the flora vary with the type of soil and its physical and chemical characteristics. Considerable etl’orts has been directed toward the establishment of the composition of the fungus flora of the soil. Mycologists in many countries have pertonned extensive and uncountable studies of the genera and species that dominate in one or another ecological circumstances, and the results of their efforts have borne fruits Although the entire dominant flora is not always well defined, a clear picture of the timgus inhabitants is now emerging .For purpose of enumeration. conventional plate counts have been most widely used, although the results are tar !rom unequivocal. This procedure permits a degree of quantitication. Such estimates of microbial density reveal the presence in soil of populations typically ranging fi·Oin as few as 20.000 to many as I 000 000 fungal propagules per gram, the propagule being considered as any spore, hypha or hypha! tragment that is capable of giving to a colony ( Alexander. 1977) .
