Fructifications solitary or cespitose, fleshy, flesh whitish; 

 pileus narrowly obconic, turbinate, truncate or depressed, gla- 

 brous, ochraceous buff, attenuated into the stem, the margin 

 thin and erect; stem short, solid, tomentose at the base; hyme- 

 nium lamelliform near the margin, rugose-wrinkled elsewhere, 

 becoming pruinose with the spores, light vinaceous drab, drying 

 drab; spores pale ochraceous in the mass, 10-13 x 4-4f m. 



Fructifications 4-10 cm. high; pileus 3-8 cm. broad; stem 1-2 

 cm. long, 8-15 mm. thick. 



On the ground in coniferous woods. Maine to Connecticut 

 and west to Minnesota, and in Montana. July to September. 



This species is intermediate between Craterellus and Cantharel- 

 lus. The marginal portion of the hymenium is like that of a 

 Cantharellus, and the remainder of the hymenium, like that of a 

 Craterellus. There is good authority for including this species 

 in .Cantharellus and there is the authority of Fries and herbarium 

 usage for classing it in Craterellus. C. clavatus is edible but too 

 rare, at least in the east, to be common in herbaria. 



Specimens examined : 

 Exsiccati: De Thuemen, Myc. Univ., 1807.
