Polyphasic taxonomy of Aspergillus section Usti
Aspergillus ustus is a very common species in foods, soil and indoor environments. Based on chemical, molecular and morphological data, A. insuetus is separated from A. ustus and revived. A. insuetus differs from A. ustus in producing drimans and ophiobolin
G and H and not producing ustic acid and austocystins. The molecular, physiological and morphological data also indicated that another species, A. keveii
sp. nov. is closely related but distinct from A. insuetus. Aspergillus section Usti sensu stricto includes
8 species: A. ustus, A. puniceus, A. granulosus, A. pseudodeflectus, A. calidoustus, A. insuetus and A. keveii together with Emericella heterothallica. Taxonomic novelties:
Aspergillus insuetus revived, Aspergillus keveii
sp. nov.
Keywords: Aspergillus; ITS; actin; calmodulin; extrolite profiles; phylogenetics; polyphasic taxonomy; β-tubulin
