The drought of 1936, culminating a series of dry years, was the most severe on record in Iowa. The year started with an accumulated moisture deficiency, and during the five months from April to July, inclusive, the average precipitation for the State as a whole was only 8½ inches, slightly less than half the long-time average for the period. The lack of rain was coupled with record breaking heat. All the months but April were above average in temperature and July was the hottest month ever experienced. Under such conditions the humus and upper layers of the soil as well as the logs on which many fungi grow were so dry that during the summer fungi of any sort were little in evidence and during most of the summer there were none to be found.
