Edibility
This species is deadly poisonous and contains lethal concentrations of muscarine, which can cause death unless treated quickly with atropine. It can be mistaken for woodland Agaricus species, which have rings and darker gills, or certain fieldcaps that lack its characteristic red staining and fibrous cap. All parts of the mushroom, including the white flesh, may bruise or age to a brick-red color, and the odor evolves from faintly sweet or soapy to rank and unpleasant.
Misidentification can be fatal. Never eat a mushroom unless you're 100% sure. This information may be inaccurate. Always consult multiple sources.
