This plant is extremely abundant about Chillicothe. I have seen hundreds of fully developed plants on a few square yards of old sawdust; and one might easily think that all the bad smells in the world had been turned loose at that place. The eggs in the sawdust can be gathered by the bushel. In Figure 449 is represented a cluster, of these eggs. The section of an egg in the center of the cluster shows the outline of the volva, the pileus, and the embryo stem. Inside of the volva, in the middle, is the short undeveloped stem; covering the upper part and sides of the stem is the pileus; the fruit-bearing part, which is divided into small chambers, lies on the outside of the pileus. The spores are borne on club-shaped basidia as shown in Figure 448, within the chamber of the fruit-bearing part, and when the spores mature, the stem begins to elongate and force the gleba and pileus through the volva, leaving it at the base of the stem, as will be seen in Figure 448. The large egg on the left in the background of Figure 449 is nearly ready to break the volva. I brought in a large egg one evening and placed it on the mantle. Later in the evening, the room being warm, while we were reading my wife noticed this egg beginning to move and it developed in a few minutes to the shape you see in Figure 447. The development was so rapid that the motion was very perceptible. The pileus is conical in shape, and after the disappearance of the gleba the surface of the pileus is merely granular. The plants are four to six inches high. The stem is hollow and tapers from the middle to each end. This plant is also known as Dictyophora Ravenelii, Burt.
