P. impudicus. Linn. 

 Pileus, conical, reticulated ; margin of the articulation 

 nearly entire. 



Stem, white, naked. — Berkeley Outlines. 



This species is not as common as the duplicatus. The volva first 

 issues out of the ground the size of a hen's ^^%, white, and consists of 

 two coats distended with jelly. Odor carrion-like. 



P. duplicatus. Laced Stinkhorn. 



Volva, globose or oval, thick, whitish, sometimes with a 

 pinkish tinge. 



Stem, cylindrical, cellulose, tapering slightly upwards. 



Veil, netted, surrounding the whole of the stipe from pileus 

 to volva, often torn. 



Head or pileus pitted after deliquescence, apex acute, six to 



eight inches high. 



Odor very repugnant, like unto rotten Limburger cheese. As disgust- 

 ing as it is to the sense of smell, so beautiful it is to the sight. When 

 perfect there can't be seen finer lacework than on this plant. It grows 

 in lawns and open woods and is easily detected by its odor. 



P. Ravenelii. B. & C. 

 Pileus, or head, conical, elongated, surface not reticulated 

 after deliquescens, the apex smooth and finally perforate.
