to white. The glossy upper surface of the cap, beneath the corky particles, varies from a brilliant red to orange-yellow, buff, and even white. Commonly in the vicinity of Washington the coloration is orange in the center, shading to yellow toward the margin. Brilliant red ones are rarely seen in this locality, but white ones are not infrequent, especially late in the season. This was the variety of mushroom that lately caused the death of a well known man in Washington. This poisonous variety is one of the largest, handsomest, and most dangerous of mushrooms, and is one whose poisonous character has been most fully studied. It is abundant in the vicinity of Washington in the fall, growing chiefly in the pine woods and, especially, in the localities which have been frequented by hogs. The chief active poisonous principle of the fly amanita is an alkaloid called muscarine, but other poisonous substances whose exact nature has not yet been discovered also occur in the plant.
