Twenty-six species of thermotolerant and thermophilic fungi were isolated from soil and water in central Saudi Arabia. Soil samples collected from a sheep market, and therefore rich in organic matter. Yielded larger numbers of thermophilic fungi than did samples from cultivated and desert regions Fewer thermophilic fungi occurred in irrigation water. In general, Large numbers were recorded at the end of the spring and summer, and again in winter. Populations were low during March, April and in the autumn. Critical temperature for the groth of the isolated fungi were determined. It was found that 30.8 per cent of the total species isolated were thermotolerant, the rest were thermophilic.
