DICTYOPHORA 



With the characters of Ithyphallus except that there is a large 

 campanulate, veil-like, netted indiisiiim that is attached to the stem 

 tip under the cap and extends far below it. Atkinson has shown 

 (1. c.) that this indiisium is a distinct organ and not homologous with 

 the short, membranous veil of Ithyphallus. The species here included 

 is the onl}^ one known in the United States. 



For literature see under the family. 



Dictyophora duplicata (Bosc) E. Fischer 



Plates 80-83 



Our largest and most massive phalloid, arising from a large egg 

 which is subspherical, ovate or sometimes flattened, about 4-4.5 x 4.5-5 

 cm., when flattened up to 7 cm. broad and 5 cm. high, white and pli- 

 cate below as in a peeled orange, the upper half smooth, pale flesh 

 color to deep flesl\y brown ; in the center below is given off a large, 

 fleshy root, and sometimes one or two smaller, more lateral ones. The 

 expanded plant may reach a height of 17 cm. with the fertile, pendent, 

 apical cap about 5 cm. long and broad, its outer surface strongly 

 chambered by anastomosing plates, over which the brownish olive slime 

 is spread. Between the cap and the stem, and hanging from the top, 

 is a beautiful net-like veil (technically the indusium) of a light rosy 

 pink color that extends below the cap for about 3-5 cm,, the perfor- 

 ations being rather regular and about 1-2 mm, broad except towards 

 the margin where they become much smaller. Stalk about 4.5 cm. 

 thick, nearly cylindrical, very hollow and with chambered walls; be- 

 tween its base and the volva is a thick, brownish yellow slime which is 

 separated from the stem by a thin membrane. The odor of the dark 

 spore slime above is offensive but not nearly so much so as in the 

 species of JIutinus, being weaker and not so distressingly fetid. 



Spores (of No, 5195) smooth, elliptic, 1,2-1.8 x 3.7-4.4/li. 



Not rare in Chapel Hill, occurring usually in a scattered colony 

 of several in woods mold in deciduous woods. Dictyophora phaUoides 

 {Phallus indusiatns) is a closely related tropical species.
