150 Mycologia 



Described from Greenbush, New York, and found rather com- 

 monly in thin woods from Vermont to North Carolina and west 

 to Indiana. This species is not generally well known, but it is 

 easily recognized after having been once carefully observed. The 

 types of B. leprosus are destroyed and B. crassipes was described 

 from notes and drawings only, so I have doubtfully referred them 

 to the present species, although I have little doubt that they be- 

 long here.

This species occurs throughout the northern United States and 

 Europe in woods and open places near woods. It may be recog- 

 nized by its rather small, yellow cap, acrid and peppery flesh, and 

 brick-colored tubes. 



19. Ceriomyces Curtisii (Berk.)

 Boletus fistulosus Peck, Bull. Torrey Club 24 : 144. 1897. (Type 



from Auburn, Alabama.) 



Described by Berkeley from specimens collected in pine woods 

 in South Carolina by Curtis. Known to occur from North Caro- 

 lina to Alabama and Mississippi. The yellow, viscid cap and 

 slender, hollow stem should readily distinguish the species. 



20. Ceriomyces inflexus (Peck)

1898. (Type from Port Jefferson, New York.) 



Described from specimens collected in open woods near Trex- 

 lertown, Pennsylvania, by Herbst. Difficult to distinguish from 

 small forms of C. scaber, except by its yellow and smaller tubes.
