As above, but gleba borne on outer surfaces of the arms Lysurus sp. 



PHALLE.^ 

 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 fi long Mutinus Curtisii 



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 Z.lA.S/i long. 



Mutinus Ravene'lii 

 (and M. caninus, if that is different) 

 Gleba borne on a pendent cap hanging from the stem tip 

 An obvious netted veil absent

Stalk reddish . • Ithy phallus rubicundus 



(reported from N. C. by Curtis) 



An obvious netted veil-like indusium pendent from the stem apex and exposed

CLATHRUS 



Receptaculum without a single di.stinct stem, but composed of an 

 inflated hollow network or of several curved columns meeting: and 

 fused above; in all cases having the spore-beariug gleba attached to 

 the inner side above as a slimy mass. Odor offensive. Only a few 

 species are known and but two have been foimd in the Ignited States. 



For literature see under the family.

Eggs subspherical, about 2.5 cm. thick, bursting above into several 

 flaps to allow the expansion of the receptacle Avhich consists of 2-5 (in 

 our plants 4-5) stout, spongy, curved and very delicate columns with 

 separate, pointed, basal ends whicii remain in the volva, the distal 

 ends incurved and completely fused into a flat roof from which hangs 

 within the dark slimy mass of the spore-bearing gleba. Color of the
