Whenspecimens of this mushroom have been eaten, the first signs of troubleare likely to appear in from one to five hours. The patient will showexcessive perspiration and respiration accompanied by vomiting. Atro-pin should be given at once, by a physician, and in large doses, whileat the same time every effort should tie made to free the alimentarycanal of the poisonous material.

It grows sometimes in open woods, sometimes in grassy places,and the specimens from which the accompanying photograph was madegrew on bare sand in the southeastern part of Kankakee county, Illi-nois. The forms which occur in these varicius habitats are so differentthat they have often been describetl as different species, but they allagree in having the stem elongated below into a root-like base andin being more or less scaly. The cap when fully expanded is 5 to 15 cm. (2 to 6 inches) the button stage it is nearly spherical and as it opens up it becomeshemispherical, then convex, and finally nearly flat. It is usually whiteor nearly so. The surface is always somewhat scaly and may be verymuch so. The scales are sometimes large and pointed and close to-gether, so that t
