SJPECIES OF CAXTHARELLUS. 43 



In some respects it approaches the European C. Brownii B. & Br., 

 but is clearly distinct from it, by its broad and very decurrent 

 lamellae, by its pruinose surface and by its umbilicate instead of an 

 umbonate pileus. 



CantkareUus crispus differs from all the preceding species in habit 

 and texture and is now referred to the genus Trogia. 



Satisfactory examples of CantkareUus tubceformis have not occurred 

 within our limits. The specimens formerly referred to this species 

 and to C. lutescens prove to be only forms of C. infundibuliformis. 



Several dimidiate and resupinate species of this genus are found in 

 Europe, but none have occurred within our limits.
