Since the publication of Part II, on Craterellus, Dr. Farlow 

 has very kindly called my attention to, and permitted me to 

 study, a specimen of a rare species from Labrador which was 

 not included in my account of our North American species. 

 This species is now described here so as to bring its description 

 and illustration continuous with those of our other species of 

 Craterellus. 



The following is suggested for insertion in ''Key to the 

 Species," on page 328 (Ann. Mo. Bot. Gard. i: 328. 1914). 



6. Pileus membranaceous, infundibuliform, pale buff; hymenium pale buff; spores 

 5-7 X 4-5^ n', from Labrador. See page 357 (Ann. Mo. Bot. Gard. i: 357. 

 1914) C. borealis 



Craterellus borealis Burt, n. sp. Plate 19. fig. 1. 



Type : in Farlow Herb. 



Fructifications solitary, small; pileus infundibuliform, taper- 

 ing uniformly to the stem, glabrous, drying between cartridge 

 buff and cream-buff, the margin entire; stem nearly equal,
