Most fungous spores are adapted to aerial dissemination and therefore the atmosphere normally contains these organisms in suspension. Aeromycological investigations have been conducted throughout the United States and in some parts of Canada either in the interest of allergy or in studies of the dissemination of the spores of fungi pathogenic to plants. Hitherto no report has been made from the Montreal area. The purpose of this survey was to make a quantitative and qualitative study of the seasonal variation in the fungous spore content of the air over Montreal.
