    Abstract:
    The objective of this investigation was to contribute towards the knowledge of microbiology of honey, more than 50 samples of honey from Slovakia and other countries were mycologically investigated in terms of the overall fungal diversity and toxicological potential of isolated fungi from Penicillium genera. The study revealed that out of 13 genera recovered, Penicillium was the most frequent and diverse genus, followed by Aspergillus and Cladosporium being found in 65.91 % (29 samples), 34.1 % (15 samples) and 29.55 % (13 samples), respectively. The most frequently encountered taxa from Penicillium genera were Penicillium chrysogenum (found in 22.73 %), Penicillium brevicompactum (13.64 %), Penicillium crustosum (11.36 %) and Penicillium griseofulvum (11.36 %). In addition, the following genera were recorded (in descending order) Mycelia (18.18 %), Fusarium (11.36 %), Mucor (9.09 %), Acremonium (6.82 %), Alternaria (4.55 %), Epicoccum (4.55 %), and finally Botrytis, Eurotium Trichoderma and Phoma all were encountered in 2.27 % of the samples being represented. The mean value counts of total fungi ranged from 0.00 to 2 × 10(2) cfu.g(-1). Outcomes from mycotoxin screening within the appropriate potentially toxinogenic species from Penicillium genera showed a number of mycotoxin producers, namely those forming citrinin (n = 1), cyclopiazonic acid (n = 5), griseofulvin (n = 5), patulin (n = 5), penitrem A (n = 2) and roquefortin C (n = 13).
