title: Possible role of solar radiation on the viability of some air fungi in Egypt.
abstract: The high occurrence of Alternaria humicola and the moderate occurrence of Stemphylium verruculosum, Rhizopus nigricans, and Epicoccum nigrum in the air of Egypt could be correlated to their apparent resistance to solar radiation. Cladosporium herbarum, Aspergillus niger, and Penicillium oxalicum, although highly occurring, were light-sensitive. The miniumum solar radiation in November, coupled with the highest total fungal catch, dominated by Cladosporium herbarum, reveals the importance of solar radiation as a factor with direct effect on the air fungal population.
