252 MYCOLOGY 



Long Island and later in Nebraska, while Anthurus horcalis has been 

 found in New York, Massachusetts and Pennsylvania. 



The family Phallace^ is represented in the eastern United States 

 by three important and interesting genera, viz., Mutinus, I thy phallus, 

 Didyophora (Figs. 99, 100, loi). Mutinus is the simplest form with 

 the gleba Ijorne on the upper portion of the stipe without the hanging 

 cap. Mutinus caninus has a hollow, perforate stipe reddish in color 

 bearing the greenish bad-smelling spore slime over its upper end. 

 Ithyphallus impudicus, our commonest species, has a globose volva, 

 cylindric, hollow spongy stalk bearing a campanulate pileus, the spore- 

 bearing surface being reticulate pitted. Didyophora duplicata, which 

 resembles the Brazihan Pilzblumen, D. phalloidea in (Figs. 100, loi) 

 the possession of a long white indusium, which hangs down beneath the 

 cap like a spread-out hoopskirt. The terminal cap is campanulate 

 and after the removal of the malodorous greenish spore slime appears 

 reticulate-pitted. The volva is prominent.
