Agaricus caseus
Agaricus caseus is Withering's 18th-century name from Britain, published when Agaricus covered almost every gilled mushroom; its modern identity is uncertain and it may not be a true Agaricus. The single GBIF record is from south-eastern Pennsylvania, so conditions come from that site and temperate agaric cultivation.
