The author isolated and identified fungi causing the internal decay of Brazil nuts (Bertholletia excelsa). The fungi included Absidia blakesleeana, A. cylindrospora, Circinella muscae, Cunninghamella elegans, Rhizopus arrhizus, R. nigricans, R. oryzae, Aspergillus flavus, A. tamarii, A. wentii, Fusarium javanicum, Penicillium frequentans, P. cf. phialosporum, P. wortmanni, Trichoderma viride and Verticillium sp. These fungi were found in nuts with normal appearance but internal spoilage, and were responsible for rancidity and bitterness of the kernels.
