Wild-harvested Mushrooms Certification

The calendar shows the months when mushroom species have been recorded in Iowa and other parts of the upper Midwest. The dates of the actual appearance of any one species can vary widely from year to year and are primarily based on environmental conditions, including ground temperature, the timing of rainfall, amount of precipitation, and season.
