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 species. It grows especially on naked soil on shaded banks or 

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

 to Canlharelhis floccosus, l)ut in every other respect it ditfers decid- 

 edly from that species. In color it resembles Cantharellus cinereus, 

 from which its more elongated pileus, shorter stem and difterent 

 hymenium at once separate it. Cantharellus cornucopioides Fr., 

 JPeziza cornucopioides L., JSIerulius cornucopioides Pers., Merulius 

 purpureus With, and Helvella cornucopioides Scop, are ancient 

 synonyms.
