Agaricaceae 



West Virginia, 1881-1885. Pennsylvania, New Jersey, frequent on 

 dung and dung heaps. May to frost. Mcllvaine. 



On mature plants, or after rains, the scales are not always present. 



P. solidipes is a handsome, readily recognized species of good weight 

 and substance. It is one of the best of toadstools. 



P. campanula' tus Linn. campanula, a little bell. Pileus oval, 

 bell-shaped or obtusely conical, sometimes umbonate, smooth, somewhat 

 shining, brownish, with a peculiar gray or lead-colored tint, sometimes 

 becoming reddish-tinted, the margin, often scalloped or fringed with the 

 appendiculate veil. Lamellae not broad, attached, becoming grayish- 

 black. Stem long, slender, hollow, reddish, pruinose and slightly 

 striate at the top, at length dusted with the spores. 



Height 4-6 in., breadth of pileus 6-12 lines. 



On horse dung and rich soil. June and July. Common. 



In very wet weather the cuticle of the pileus sometimes cracks into 

 scales or areas. Peck, 23d Rep. N. Y. State Bot. 



Spores subellipsoid, 16-18x10-13^ K.; 8-9x6/4 Massee. 



Mr. R. K. Macadam, Boston, Mass., informs me that he has infor- 

 mation of a case of poisoning by this fungus. "The victim experi- 

 enced dizziness, dimness of vision, trembling and loss of power and 

 memory. He recovered after simple treatment and was well inside of 

 24 hours." 



A full account of this case is in "The London Medical and Surgical 

 Journal," Vol. 36, November, 1816. The poison acts as a sedative. 



I have several times eaten of this fungus in small quantities, because 

 larger could not be obtained, and with no other than pleasant effect. 

 There does not appear to be any case of poisoning reported by it since 

 1816, which, considering the inquisitiveness of man, is singular. Caution 

 is advised. 



P. papiliona'ceilS Fr. papilio, a butterfly. Pileus subhemispherical, 

 sometimes subumbonate, smooth, or with the cuticle breaking up into 

 scales, whitish-gray, often tinged with yellow. Lamellae very broad, 

 attached, becoming black. Stem slender, firm, hollow, pruinose above, 

 whitish, sometimes tinged with red or yellow, slightly striate at the top 

 and generally stained by the spores. 



Height 3-5 in., breadth of pileus 6-18 lines.
