Aspergillus ochraceoroseus produces the yellow-gold conidia and other charactertistics of Aspergillus subgenus Circumdati section Circumdati. However, it produces aflatoxin, a secondary metabolite characteristic of some members of Aspergillus subgenus Circumdati section Flavi and sterigmatocystin, a related secondary metabolite usually associated with Aspergillus subgenus Nidulantes sections Nidulantes and Versicolores, and members of several other genera. Our morphological data supports the placement of A. ochraceoroseus in subgenus Circumdati. Sequence data from A. ochraceoroseus aflatoxin and sterigmatocystin genes aflR and nor-1/stcE, as well as 5.8S ITS and beta tubulin genes was compared to that of aspergilli in sections Circumdati, Flavi, Nidulantes and Versicolores. In the sequence comparisons, A. ochraceoroseus was more closely related to the species in subgenus Nidulantes than to species from subgenus Circumdati.
