Atmospheric fungi in the desert town of Arad and in the coastal plain of Israel.

A two years' volumetric survey of the airborne fungi in the arid town of Arad revealed markedly lower spore concentrations than in the coastal region of the country. Low incidence prevailed throughout the year except for high peaks in October-November, closely related to the distribution of Cladosporium spores. Air-spora composition, annual frequency and seasonal variation of fungal genera and species at the two sites were compared.
