are all summer months. Thirty-nine genera were isolated of which Aspergillus, Penicillium, Fusarium, Mucor, Rhizopus and Humicola were of high seasonal occurrence. Seven genera were of moderate occurrence and these were Cochliobolus,Stachybotrys, Paecilomyces, Cunninghamella, Myrothecium, Chaetomium and Sepedonium. The remaining genera were of low or rare seasonal occurrence. Aspergillus showed its highest prevalence during the periods May-September 1972 and April-August 1973, Twenty-four species of Aspergillus in addition to two varieties of A. nidulans were isolated, of which A. niger, A. fumigatus, A. terreus, A. nidulans and A. sydowii were dominant. Thirty species of Penicillium were identified, Of which P. notatum, P. funiculosum and P. chrysogenum were of high seasonal occurgence. Penicillium predominated during winter and spring months.

## Abstract 73 species which belong to 24 genera were collected in 200 and 35 esposures made during the period May 1976βOctober 1977 at each of two levels (2 m and 20 m). The airβborne fungi showed seasonal periodicities and the highest incidence was recovered in spring and autumn and the least in
