title: Properties of Aspergillus tamarii, A. caelatus and related species from acidic tea field soils in Japan.
abstract: Fungi in Aspergillus section Flavi include both aflatoxin producers and non-producers. Aspergillus caelatus is a recently described non-aflatoxigenic species in this section, which has some common characteristics with A. tamarii, such as yellowish brown color and double walled spores. In contrast to the morphological similarities, all of the A. caelatus isolates tested produced no cyclopiazonic acid whereas most isolates of A. tamarii produce this compound. There are six nucleotide differences that distinguish the DNA sequences of these two species in the regions of ITS1, ITS2, 5.8S rDNA and 28S rDNA and this is a consistent difference. Both species were isolated from acidified field soils, but A. tamarii isolates were more common than A. caelatus in highly acidic soils.
