SPECIES OF CANTHARELLUS. 35 



In Leptocantharellus the pileua is fleshy but thin, and floccose, 

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

 shaped and sometimes pervious. The lamellse 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.
