Pollen and mold spores. An atmospheric and field survey in Los Angeles.
A two-year survey of pollen and mold spores by the gravity slide method revealed that there are no clear-cut tree, grass or weed pollen seasons in California. Pollen counts should be correlated with field studies to distinguish the various plants whose pollen have a similar appearance. Spores of Alternaria and Hormodendrum, whose importance in allergic disease of the respiratory tract has been well established for many years, were found all during the year. More hormodendrum spores were collected than the total of all other pollens combined.
