Mycologia 



Fisch., another very fetid stinkhorn, abundant in Europe and 

 reported rarely in this tountr), has no veil of any kind, although 

 its pileus is reticulated similarly to that of the veiled stinkhorn. 

 Both of these species may be exterminated in lawns and groves 

 by the use of quick-lime, as described in Mycologia for March, 

 1909. 



Mutinus elegans (Mont.) Ed. Fisch. 

 Headless Stinkhorn 



Plate 17. Figure 6. X i 



Stipe horn-shaped, cylindric, tapering gradually to the apex, 

 pitted, hollow, white or pinkish below, bright-red or orange above, 

 10-17 cm. long, about 2 cm. thick; apex conic-acuminate, per- 

 forate ; gleba greenish-brown, semifluid, fetid, smeared over the 

 tipper portion of the stipe in an indefinite manner; spores oblong- 

 ellipsoid, 4-5 X 2 />t ; veil none ; volva oblong-ovoid, pinkish, 

 2.5-3 cm. long. 



This species is very conspicuous by reason of its size and 

 brilliant coloring. It occurs rather commonly in the United 

 States in rich cultivated grounds or woods. A smaller species, 

 Mutinus caninus (Huds.) Fries, found rarely in the eastern 

 United States and also in Europe, may be readily distinguished 

 by its more distinct pileus and very faint odor. Both species 

 readily lose the greenish slime containing the spores, since this 

 is eagerly devoured by flies and easily washed away by h'ght 

 rains. 



Scleroderma aurantium (L.) Pers. 



Common Scleroderma. Hard-skinned Puffball 



Plate 17. Figure 7. X i 



Peridium depressed-globose, subsessile, radicate, often cespi- 

 tose, 2.5-8 cm. in diameter, thick, corky, usually pale with yellow 

 shades, or orange, sometimes brown, mostly covered with large 

 warts ; gleba at first white, then vinaceous to bluish-black, finally 

 greenish-gray, lines of trama whitish ; spores dark, globose, 

 warted, 7-12 /x. 



A very common and widely distributed species growing in dry 

 v^oods, especially under chestnut trees. I have eaten the young 

 •sporophores, but do not consider them attractive. Persons have
