Two fungi, Boletus edulis and Agaricus bisporus, were tested as substrates for two known aflatoxigenic fungi, Aspergillus flavus ATCC 15548 and A. parasiticus NRRL 2999. Both autoclaved substrates supported mycelial growth, sporulation, and aflatoxin production; however, the B. edulis substrate allowed more rapid mold growth and greater toxin production than did the A. bisporus substrate under laboratory conditions. Both aflatoxins B 1 and AFG 1 were produced with AFG 1 being the predominant toxin. Aflatoxins B 2 and AFG 2 were not detected. Although toxin was produced at low levels, the highest mean being 0.55 μg/g substrate for AFB 1 and AFG 1 , both mushrooms apparently contained minimal nutrients for toxigenic mold growth and failed to cause antimycotic or antiaflatoxigenic responses. Routinely used aflatoxin extraction and analytical procedures appear applicable for such testing of mushrooms.
