    Notes: Abstract One hundred different cultivars and lines of broad bean (Vicia faba L.) seed samples were inoculated with Aspergillus flavus Link (CMI 102135) to determine varietal differences which may support or resist aflatoxin production. Thin-layer chromatographic analysis of the chloroform extracts of the different seed samples revealed that 11 cultivars/lines were highly resistant to seed invasion and aflatoxin production while 9 cultivars/lines showed partial resistance. The remaining 80 samples were susceptible to the establishment of A. flavus and aflatoxin accumulation. All the resistant cultivars/lines seed samples were inoculated also with three local isolates of fungi namely; Stachybotrys chartarum (Ehrenb. ex Link) Hughes, Aspergillus ochraceus Wilhelm, and Fusarium oxysporum Schlecht. The resistant seed samples were also resistant for colonization with these fungi and mycotoxin formation.

    Notes: Abstract Thirty-eight genera and 81 species of fungi were isolated and identified from 120 samples of 24 kinds of spices collected from different places at Assiut Governorate, Egypt. Predominant genera wereAspergillus (25 species) andPenicillium (7 species) of whichA. flavus, A. niger, A. ochraceus, A. fumigatus, A. flavus var.columnaris, A. terreus, P. chrysogenum andP. corylophilum were the most commonly occurring.

    Notes: Abstract Fungal flora of 20 samples of lentil seeds collected from Assiut governorate, Egypt, were studied. Seventeen genera and 13 species were isolated on glucose- (15 genera and 27 species), cellulose-(15 genera and 25 species)Czapek's agar media at 28 °C. The most common species were as follows: on glucose-Czapek's agar, Aspergillus fumigatus, A. niger, A. flavus, A. terreus, Penicillium notatum and Rhizopus oryzae and on cellulose agar, A. fumigatus, A. niger, A. flavus and P. notatum. Thin layer chromatographic (TLC) analysis and a biological test (Artemia salina) indicated the presence and the toxicity of aflatoxin in the extract of one sample (aflatoxins B1, B2, G1 and G2, at 20 mg/kg, total). This is the first report of the natural occurrence of aflatoxins in lentils.

    Notes: Abstract From 40 peanut seed samples collected in Egypt, forty-three species and one variety of fungi, belonging to 16 genera, were collected. The most dominant genera were Aspergillus (11 species + one variety), Penicillium (11 species) and Fusarium (4 species). From the preceding genera A. fumigatus, A. flavus, A. niger, P. chrysogenum and F. oxysporum were the most frequent species. Forty-nine isolates belonging to 12 species and one variety were tested for production of mycotoxins, after growth on liquid medium containing two carbon sources (sucrose or cellulose). Thin layer chromatographic analysis revealed that the quality and quantity of mycotoxins was higher on sucrose than cellulose. Mycotoxins identified were aflatoxins B1, B2, G1 & G2, citrinin; fumagillin; diacetoxyscirpenol T-2 toxin; satratoxin H; and zearalenone.
