The complexity of Aspergillus has been emphasized by the diversity of teleomorph and the heterogeneity of ubiquinone systems. The resolution by traditional morphological approaches has been limited, and a need for newer approaches has become apparent. Current trends in Aspergillus chemotaxonomy are presented based mainly on our previously published and unpublished data on electrophoretic comparisons of enzymes and their numerical analyses, ubiquinone systems, and partial sequences of 18S ribosomal RNA. Combinations of such chemotaxonomic indicators including nuclear DNA base composition and DNA-DNA homology support or bring into question taxonomic decisions in recent years based primarily on the morphological species concepts in Aspergillus and associated teleomorph, while further comparisons of 18S ribosomal RNA partial sequences can shed light on the phylogenetic and evolutionary background of both.
