Extract from Wikipedia article: Agaricus pocillator, a woodland mushroom, is distributed through southeastern North America in ranges at least as far north as Illinois. It can be distinguished in the field by its dark center, its small, bulbous base, which stains yellow, and its relatively slight stature. It is very similar to Agaricus placomyces, but is a slightly smaller mushroom with a scalier cap and a more northern range within the United States. Edibility is not certain for Agaricus pocillator, but several other yellow-staining Agaricus species are poisonous. Hikers are often warned to avoid eating it when spotted.
