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- 

 ren co. July. 



Hypomyces camphorati n. sp. 



Subiculum thin, effused, overrunning and obliterating the 

 hymenium of the host plant, yellow; perithecia numerous, minute, 

 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 

 broad. 



On the hymenium of Lactarius camphoratus. 

 Port Jefferson, Suffolk co. August. 



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

 by its yellow subiculum, its longer asci and acute or cuspidate 

 spores.

 lose on the margin, grayish brown; lamellae subdistant, broadly 

 sinuate, adnexed, ventricose, at first whitish, then brownish or 

 rusty brown; stem short, firm, solid, silky fibrillose, whitish in the 

 upper part, grayish brown and subsquamulose toward the base; 

 spores subglobose, nodulose, .0003 -.0004 of an inch long, .0003 

 broad. 



Pileus 3-6 lines broad; stem 4-8 lines long, about 1 line thick. 

 Bare compact soil in wood roads. Wading River. August. 



A small but distinct species belonging to the section Lacerae.
