P. pisocar´pium Fr. Gr—a pea; Gr—fruited. Peridium irregularly globose, indistinctly nodulose, passing downward into a stout stem-like base; peridiola irregularly angular, 4–5×2–3µ, yellow. Spores globose, warted, coffee-color, 9–13µ Massee.
P. pisocarpium was quite common at Mt. Gretna, Pa., from August to October, 1898, in open pine and mixed woods, growing from sandy ground. The height reached 5 in. and diameter 2 in. The shapes were usually those of inverted pears, more or less flattened along their lengths. Skin hard, polished, olivaceous-black with dull yellow mottlings, not unlike rattlesnake skin. When broken the peridiola (small ovate cylinders which bear the spores within) are very distinct, often over ⅛ in. long. The entire interior is dark when mature, and the rupture of the plant is irregular and by disintegration of the upper part. They often dry without rupturing. Search as I would, I could not find a young one, or one in edible condition. The plant is here given because interesting and one the student will wish to identify. It is so odd that it is not surprising to find it employed as a medicine in China.
TOADSTOOL POISONING AND ITS TREATMENT
By W.S. Carter, M.D.

The poisonous mushrooms, or so-called toadstools, may be grouped in two classes: (1) Those containing minor or irritant poisons, which act locally on the gastro-intestinal tract, such as the Clitocybe illudens, Lepiota Morgani and others, and (2) those containing major poisons which act on the nerve centers after absorption, causing symptoms to appear a long time after the poison has been taken and very often terminating fatally. This group includes the Amanita muscaria, the Amanita bulbosa or Am. verna and the Amanita phalloides.
From the prompt way in which vomiting and purging begin after eating the toadstools of the first group there seems to be no doubt of the local irritant action on the alimentary canal. Grave symptoms from any constitutional effect or any serious disturbances of the circulation do not occur. Although intensely disagreeable, such poisoning terminates in recovery and may not be regarded as dangerous unless the poison be taken in enormous quantity or by one in poor health.
In poisoning by the deadly toxic Amanitæ vomiting and purging may also occur as prominent symptoms, but generally only occur late—ten to fifteen hours after eating the toadstool—and are due to the action of the poison on the nerve centers. This is clear from the fact that these symptoms appear when the poison is given either hypodermatically or intravenously to animals.
It is exceedingly unfortunate that these deadly poisonous toadstools do not give some warning either in an unpleasant taste or contain an irritant which would act locally to cause emesis and purgation, for in that case the patient would get rid of the poison before such large quantities were absorbed and fatal poisoning would be less frequent. They are not at all unpalatable and sometimes large quantities are eaten by mistake.
