type and with the specimens of C. unicolor in five different 

 copies of Ravenel's Tungi Caroliniani.' C. corrugis is certainly 

 the same species as C. unicolor. It is very strange that in the 

 interval of nearly half a century from the time of the original 

 collection, C. unicolor did not attract attention from an inter- 

 mediate station. 



Specimens examined: 

 Exsiccati: Ravenel, Fung. Car. II. 26; Ell. & Ev., N. Am.

 lection dated Nov. 2, also the type (in Coll. N. Y. State)

Fructifications gregarious, fleshy-spongy, drying sorghum- 

 brown to fuscous; pileus somewhat clavate to turbinate or 

 narrowly obconic, truncate, or somewhat convex, at first yel- 

 lowish cinnamon, then becoming tinged with fuscous, the edge 

 obtuse; stem solid, paler than the pileus, often bulbous at the 

 base; hymenium corrugated and rugose-wrinkled, colored like 

 the pileus, drying sorghum-brown to fuscous; spores even, 10-12

 3-6 cm. long, 4-12 mm. thick. 



On ground in woods under coniferous trees. New Hampshire, 

 Vermont, and Michigan. August to October. 



Specimens of this species have so nearly the coloration of C. 

 unicolor that those, small and undeveloped, in a collection of 

 C. pistillaris cannot readily be distinguished from partially 

 developed specimens of C. unicolor; but with age, those of C
