Melanosporae 



On dung and rich soil. Common. May and June. Paneeoius. 



A small form occurs with the pileus nearly white, scarcely half an 

 inch in diameter, and the cuticle not cracking. Peck, 23d Rep. N. Y. 

 State Bot. 



The effects of P. papilionaceus are very uncertain. I have seen it 

 produce hilarity in a few instances, and other mild symptoms of intoxi- 

 cation, which were soon over, and with little reaction. But I have seen, 

 at table, the same effects from eating preserved peaches and preserved 

 plums which had fermented. Many personal testings have been with- 

 out effect. Testings upon others vary with the individuals. The fungus 

 seems to contain a mild stimulant. It is not dangerous, but should be 

 eaten with caution. Being of small size, and not a prolific species, 

 quantities of it are difficult to obtain. Moderate quantities of it have 

 no effect whatever.
