pileus is conical in shape, and after the disappearance of the gleba the surface 

 of the pileus is merely granular. The plants are four to six inches high. The 

 stem is hollow and tapers from the middle to each end. This plant is also known 

 as Dictyophora Ravenelii, Burt.

The receptacle is borne on a stalk, hollow, attenuated toward the base, divided 

 above into arms, which do not join at their apices, and which bear the spore mass 

 in their inner surfaces and sides, inclosing the spore mass when young, but later 

 diverging. 



The stem of the phalloid is white, hollow, attenuated downward ; the arms are 

 narrow, lance-shaped, with pale flesh-colored backs, traversed their entire length 

 by a shallow furrow. 



The egg in the center is about ready to break the volva and develop to a full 

 grown plant The plants in Figure 450 were found near Akron, Ohio, and 

 photographed by G. D. Smith.

The gleba is borne directly on the upper portion of the stem, which is hollow 

 and composed of a single layer of tissue ; and the plant has no separate pileus, 

 by which characteristic the genus differs from Phallus.
