Puffballs of the fleshy interior becomes filled with dust-like spores, when the rind of the ball breaks to let the spores escape. Sometimes the wall breaks off in scales ; sometimes it is punctured at the summit with one hole, sometimes with several, and sometimes it splits and turns back to form a star on the ground. Sometimes the balls contain elastic threads (capillitium), which help to push out the spores, and sometimes they do not. Sometimes there are threads massed at the base without spores in them, so that they form a sterile base or sterile subgleba, and sometimes the threads are massed to form a central column (columella) in the interior of the ball. These characters, with others, form the basis on which the puffballs are separated into the genera Ly coper don, Geaster, Calvatia, Bovistella, Bovista, and Colostoma.. GENUS LYCOPERDON The Lycoperdons, or true puffballs, produce within the ball vast numbers of dust-like spores mingled with elastic threads. When the ball is compressed, the rind or peridium bursts at the summit to form a single mouth, and the elastic threads cause the spores to fly out in puffs like smoke. The spore-bearing part of the plant is globe-shaped, obovoid, or top-shaped, and at the base of the gleba no spores are pro- duced ; the cells here are coarse and empty. The rind or peridium of the ball con- sists of two parts, the outer bark or outer peridium being adorned with spines or scales or warts or gran- ules. Sometimes the exterior coat may be peeled off, sometimes it dries and falls away in fragments. The inner coat is thin and papery, and opens on the top with one opening. At first the ball is fleshy within, the microscope showing the flesh to con- sist of a great number of simple or branched threads and enlarged cells. The enlarged cell
