252 MYCOLOGY 



Long Island and later in Nebraska, while Anthuriis borcalis 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, Ithyphallus, 

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

 the gleba borne 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. 

 Ithyphalltis 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 Brazilian Pilzblumen, D. phaUoidea 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.
