Details

The records are drawn from G. H. Lincoff (1981) (Pres.), The Audubon Society Field Guide to North American Mushrooms. New York: Alfred A. Knopf. (See pages 500--525 for the Agaricus and Lepiota Family.)

The Guide clearly states that there is no simple rule for determining the edibility of a mushroom; no rule like “leaflets three, let it be” for Poisonous Oak and Ivy.

The actual dataset from the UCI repository has been cleaned up to properly label the missing values and have the full category names instead of their abbreviations.
