From the 1881 Household Cyclopedia

Be careful in gathering mushrooms that you have the right kind: they are pink underneath and white on the top, and the skin will peel off easily, but it sticks to the poisonous ones: and the smell and taste of the good ones are not rank. After you have peeled them, sprinkle them with salt and pepper, and put them in a stewpan, with a little water and a lump of butter. Let them boil fast ten minutes, and stir in a thickening of flour and cream. They may be fried in butter, or broiled on a gridiron. They are sometimes very abundant in the fall, on ground that has not been ploughed for several years; they appear after a warm rain. They may be peeled, salted, and allowed to stand for some hours before cooking.

Warning: Many types of mushrooms are poisonous, and some of these closely resemble edible varieties. Only those expert in distinguishing between mushroom types should attempt to gather wild mushrooms for cooking.
