In nutrient plates exposed in 1947 in the arctic and subarctic from aircraft for two minutes by hand, 1062 colonies developed in 51 plates. Cultures were made from typical colonies on corn meal agar. Of the 208 cultures, 55 were non-sporulating. Cladosporium was the most frequently isolated organism with 33 (15.8%) cultures, most being C. herbarum. Other genera isolated were Streptomyces 23 (11%), Sporormia 17 (8.1%), Penicillium 13 (6.2%), Pullularia 11 (5.4%), Verticillium 7 (3.2%), Stemphylium 6 (2.7%), Phoma 4 (1.8%). Botrytis, Alternaria, Phialophora, yeast two each, with a single culture of Cephalosporium, Chaetamium, Fusarium, Gliocladium, Papularia, Pestallozia, Sphaeronema. With the possible exception of Sporormia the fungi are considered to be largely saprophytic soil borne organisms carried into the arctic by southerly winds.
