Abstract

A recent report of an aflatoxin producing isolate of Aspergillus tamarii prompted a taxonomic re-examination of aflatoxigenic and non-aflatoxigenic isolates identified as A. tamarii as well as the closely related A. caelatus. Representatives of each species, including atypical isolates, were compared morphologically, for mycotoxin production, and for divergence in ITS, 28S, β-tubulin and calmodulin gene sequences. Because of genetic, morphological, and mycotoxin differences, the aflatoxin producing isolates of A. tamarii are given species rank as Aspergillus pseudotamarii sp. nov.
