Mushrooms. 10 usually more or less distinctly and irregularly checked, the white color of the interior showing between the darker, raised areas. Within at its earliest stage the flesh is of a milk-white color, solid, and without an appreciable juice. Within two or three days it becomes soft, turns yellowish, develops a watery and later an amber- colored juice, and continues its development through later stages. In the left-hand specimen of fig. 9 the entire contents have changed from yellow to brown, the juice has dried out, the outer coatings on the upper part have been broken up and blown away, showing only in brown and gray at the lower edge of the specimen, and the inte- rior mass of dustlike spores and fluffy minute brown threads is exposed to the air. In the right-hand specimen the process has gone a step further and a large part of the contents of the puff ball have.

From the character of the fungus at this stage has arisen a name by which it is familiarly known among the colored people in the vicinity of Washington, "the devil's snuff ; Fig. 10 shows further stages in the plant's history. In the right-hand specimen is shown the final form of the plant. It is dry and leathery, the spores all blown away, and the slender threads beaten down by the rain and dried together on the surface into a smooth skin. The specimen is tilted forward, but viewed directly from the side it would present roughly the form of a broad urn. This is the characteristic form of an old puffball of this species. In none of the stages shown in figs. 9 and 10 is the puffball edible. It is too dry and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble th
