the free development of the pileus. When young, the pileus is 

 whitish or white tinged with yellow. It soon assumes a buff color, 

 with the margin commonly tinged with blue and becoming a darker 

 blue where bruised. In old specimens the center or sometimes the 

 whole becomes ferruginous brown. The aculei are at first white 

 but they become brown or ferruginous brown with age. The spores 

 are purplish brown, subglobose or oval, .00016 of an inch in diame- 

 ter. 



The plant has a farinaceous odor when cut or bruised. It is 

 sometimes cespitose. It grows under hemlock trees. Horicon, War-

Hypomyces camphorati n. sp. 



Subiculum thin, effused, overrunning and obliterating the

 immersed in the subiculum, the ostiolum exposed, brown; asci very 

 long, .005-. 006 of an inch (sporiferous part), eight spored; spores 

 monostichous, oblong fusiform, continuous, acute or slightly 

 cuspidate at each end, .0005-. 0006 of an inch long, .0001 6-. 0002

Closely allied to H . v o 1 e m i Pk. from which it is distinguished
