type and with the specimens of C. unicolor in five different 
copies of Ravenel’s ‘Fungi 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. 
Fungi, 1922a under the name C. pistillaris.

lection dated Nov. 2, also the type (in Coll. N. Y. State) 
of C. corrugis; Lynn, H. Webster; Medford, Mrs. Page and 
Mrs. De Long, ex Herb. Boston Mycological Club, 420;

*Fungal Flora'; West Chester, B. M. Everhart, Ell. & Ev., 
N. Am. Fungi, 1922a.

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 
x 6-8 и. 
Fructifications 6-12 em. high; pileus 2-33 сіп. broad; stem 
3-6 em. 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.
