SPECIES OF CANTHARELLUS. 35 



In Leptocanthakellus the pileus is fleshy but thin, and flooeose, 

 fibrillose or pruinose. It is umbilicate, centrally depressed or funnel- 

 shaped and sometimes pervious. The lamellae are mostly sparingly 

 branched, and the slender stem is generally hollow. The last three 

 groups contain species which have their respective counterparts or 

 corresponding species in the genus Craterellus. 



In the diagnosis of the genus which I have quoted the spores are 

 said to be white, but in some of our species they vary considerably 

 from this color. 



The name of the genus is derived from cantharus, a kind of drink- 

 ing cup.
