This is our most common Craterellus. It is easily recognized by 

 its elongated tubular or narrowly trumpet-shaped pileus and its dingy- 

 gray or smoky-brown hue. The pileus is thin but rather tough and 

 elastic. The hymenium is generally a little paler than the pileus 

 and varies in color from cinereous to reddish-brown and dark smoky- 

 brown. It sometimes becomes pruinose when dry. The stem is 

 short or almost obsolete, the hymenium extending nearly or quite to 

 the surface of the ground. The spores are larger than in any of our 

 other specie.s. It grows especially on naked soil on shaded banks or 

 knolls or in old roads in woods. In shape it corresponds very closely 

 to CanthareUus floccosus % but in wwy other respect it differs decid- 

 edly from thai species. In color it resembles CanthareUus dnereus, 

 from which its more elongated pileus, shorter stem and different 

 hymenium at once separate it. CanthareUus cornucopioides Fr., 

 Pezi:.<i < ■>>, itiicopioides L., MeruUus cornucopioides Per-.. MeruHus 

 purpureus With, and Helvetia cornucopioides Scop, are ancient 

 Bynonyms. 



Craterellus dubius PA. 

 Doubtful Craterellus. 



Pileus thin, infundibuliform or subtubiform, subfibrillose, dark- 

 blown or lurid-brown, pervious, the margin generally wavy and
