Aspergillus: An Overview

Part of the NATO ASI Series book series (NSSA, volume 102)


Since 1965, approximately 80 species in Aspergillus have been described as new and thousands of publications have contributed to our knowledge of biochemical and ultrastructural features. The group concept, developed in the monographs of 1926, 1945 and 1965 has been a tremendous aid in species identification. Sixteen of Raper and Fennell’s 18 groups have been validated by the contributions of the last 20 years. Only the A. ornatus and A. wentii groups appear to be heterogenous. An analysis of the Aspergilli listed in 62 recent soil surveys has revealed highest absolute and relative numbers of species in the subtropics, particularly in cultivated soils, saline soils and subtropical deciduous forest soils. In temperate regions, highest numbers of species have been reported from desert soils and certain grassland soils. Unusual species in the soils of western US intermountain basins may have evolved following early migration, then isolation and specification through the Pleistocene.
