Key to the Phalloids of the United States* 



Clathreae 



Receptaculum composed of a stout, netted globe Clathrus cancellatus (p. 6) 



Receptaculum composed of two to five stout columns fused only above Clathrus columnatus (p. 5) 



Receptaculum composed of a relatively short stalk which divides above into three or more arms which 

 are simple, widely separated and united at their tips, the gleba enclosed in the apical part of 



the arms Coins Schellenbergiae (p. 7) 



Receptaculum composed of a single distinct, relatively long stalk bearing a subglobose, netted, spore- 

 bearing part on the end; red above Simblum sphaerocephalum (p. 7) 



Receptaculum as above, but color yello w all over Simblum texense 



Receptaculum stalked as in Simblum, but the apical spore-bearing part composed of several (usually 

 six) short, hollow arms, incurved and meeting above at first and enclosing the gleba; stalk 

 white Antkurus borealis (p. 8) 



PhaLleae 



Gleba (and spore slime) borne on the upper part of the stalk itself 



Stalk 10-17 cm. long, tapering gradually from the center upward to a rounded point; spores 4.7/i 



long Mulinus Curlisii (p. 10) 



Stalk 6-8 cm. long, nearly cylindrical except for the tapering base (at times) , the tip rather abruptly 



rounded and the spore-bearing part more or less sharply delimited from the sterile part; 



spores 3.7—1.8ju long Mutinus Ravenelii (and M. caninus, if that is different.) (p. 9) 



• All except Simblum texense are found east of the Mississippi.
