Washington University 
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 “Кеу to the 
Species," on page 328 (Ann. Mo. Bot. Gard. 1: 328. 1914). 
6. Pileus membranaceous, infundibuliform, pale buff; hymenium pale buff; spores 
5-7 x 4-54 u; from Labrador. See page 357 (Ann. Mo. Bot. Gard. 1:357.
