The genuine Mushroom is found in Autumn, on rich, old pastures. It has a small, round, brownish-white head, of a delicate pink color underneath the stem is generally from two to three inches high.

Spread it on the floor of an open shed, to remain till it becomes firm enough to be formed into square flat bricks; which done, set them on edge, and frequently turn them till half dry; then with a dibble make two or three holes in each brick, and insert in each hole a piece of good old spawn, about the size of a walnut,” or the spawn which consists of fine white threads that may be found where mushrooms are growing in pastures. “The bricks should then be left till they are dry. This being completed, level the surface of a piece of ground, under cover, three feet wide, and of sufficient length to receive the bricks; on which lay a bottom of dry horse-dung, six inches thick; then form a pile, by placing the bricks in rows, one upon another, with. the spawn side uppermost, till
