| Aflatoxins are among the most carcinogenic natural compounds known, and have been frequently detected in numerous agricultural commodities, nut fruits being among the most contaminated ones. These toxins are a result of the secondary metabolism of fungi belonging to the genus Aspergillus Section Flavi, namelly Aspergillus flavus, A. parasiticus and A. nomius. The early detection of aflatoxigenic fungal contamination and the preventive control of aflatoxin production seems to be the only viable way to respond to the rigorous limits imposed by EU legislation. In Portugal, knowledge on mycoflora and mycotoxigenic profiles of almonds is scarce. Our objective was to characterise portuguese almonds in respect to mycoflora, with strong emphasis on aflatoxigenic... |

| Aspergillus subgenus Circumdati section Flavi, also referred to as the A. flavus group, has attracted worldwide attention for its industrial use and toxigenic potential. Section Flavi is divided in two groups of species. One includes the aflatoxigenic species A. flavus, A. parasiticus and A. nomius, which cause serious problems in agricultural commodities, and the other one includes the non‐aflatoxigenic species A. oryzae, A. sojae and A. tamarii, traditionally used for production of fermented foods. Differentiating aflatoxigenic from non‐aflatoxigenic species and strains in food commodities is of major importance in food quality control. A polyphasic approach consisting of morphological, chemical and molecular characterization was applied to 31 isolates... |

| The National Plan for Solid Waste has set out to reduce by 25% the amount of organic waste disposed of in landfills, mostly food residues from street fairs, besides determining the implementation of municipal composting plants, and it also mentions improving the capacity of plants already installed. The purpose of the study was to analyze which decomposing fungi are involved in the different composting phases, in a plant located in the city of São Paulo. Data was collected in four composting seasons from 2016 to 2017 and the analysis of 49 samples showed twelve genera belonging to the Ascomycetes and Zygomycetes phyla, but only at the mesophilic phase. In all seasons, yeasts and Aspergillus fumigatus were predominant with a total count of 1.0 x 109 cfu g-1... |

| In a survey of Agaricales fungi in Seasonal Semidecidual Forest remnants from Paraná State, southern Brazil, two Clitocella and two Rhodocybe species were identified. Based on morphological data, Clitocella pallescens is described as a new species, and a new combination is proposed to Clitocella himantiigena. Rhodocybe galerinoides and C. himantiigena are new records from Brazil. Rhodocybe caelatoidea, already registered in Paraná State, is also described, illustrated and discussed. |
