AIR-BORNE FUNGI IN THE ARCTIC AND OTHER PARTS OF CANADA
Quantitative and qualitative studies were made of the fungi in the air over various parts of Canada and Alaska, continuing studies in arctic aerobiology. In winter, arctic air is apparently sterile: in summer, at Ft. Churchill, Man., ground level samples varied from 0.5 to 4.4 per cu. ft. Cladospori...

Quantitative and qualitative studies were made of the fungi in the air over various parts of Canada and Alaska, continuing studies in arctic aerobiology. In winter, arctic air is apparently sterile: in summer, at Ft. Churchill, Man., ground level samples varied from 0.5 to 4.4 per cu. ft. Cladosporium was the commonest fungus (average 0.5 per cu. ft.), followed by yeasts (0.16), Penicillium (0.06), and Stemphylium (0.03 per cu. ft.). Other fungi present were Pullularia, Botrytis, Aspergillus, Verticillium, Pyrenochaete, Helminthosporium, Phyllosticta, Papularia, Cunninghamella, and Sporormia. Of 3711 colonies 57% failed to sporulate. Silicone slide readings as high as 114.9 fungus spores per cu. ft. were obtained and included the following: yeasts (8.6), Cladosporium (3.8), smuts (2.5), Fusarium (0.6), Alternaria (0.06 per cu. ft.), Venturia, Cercospora, Septoria, rusts, Leptosphaeria, Sordaria, and Pleospora and many hyaline one-celled spores.
