Notes: This mushroom is common, easy to identify, delicious, and impossible to bring to market or preserve well. For eating, the mushrooms should be white, have white to pink gills, have absolutely no deliquescing black bits and be eaten within hours of harvest. They also should not be harvested anywhere there is a chance of chemical or environmental contamination. Clean them by rubbing or scrapping, never with water.
