Craterellus Pers. Мус. Eur. 2:4. 1825.—Fries, Epicr. 531.

The type species of the genus is Craterellus cornucopioides 
L. ex Pers. 
Fructifications fleshy or membranaceous, pileate, often tubi- 
form, infundibuliform, or flabelliform, sometimes clavate; 
hymenium waxy-membranous, distinct, continuous, adnate to 
the hymenophore, even or rugose; basidia simple; spores usually 
white. 
Craterellus is closely related by its fleshy C. Cantharellus, 
C. odoratus, C. lutescens, etc., with the genus Cantharellus. 
These species resemble so closely in coloration and habit species 
of the latter genus that careful examination of the hymenium 
should be made for generic determination. Craterellus has 
its hymenium even or slightly rugose. In exceptional con- 
necting species, such as C. clavatus, it is somewhat lamelliform 
for a part of the distance from margin of the pileus to the stem. 
The clavate C. pistillaris and C. unicolor connect Craterellus 
closely with Clavaria. 
Craterellus cornucopioides, C. ochrosporus, C. clavatus, С. 
Cantharellus, and С. odoratus are edible species, which are often 
abundant locally.
