Agaricus semotus is a woodland mushroom of the Agaricales order of fungi. It, like many of its relatives, can be found spread throughout wooded, moist areas in the southern United States, and has been found in areas ranging from California to Florida; it is also indigenous to Great Britain and Europe. A. semotus has also been collected in New Zealand. Although various authors disagree about its edibility, its modest size prevents it from being a significant source of nutrition.
