Pileus 6 to 15 lines broad ; stem about 1 in. long", 1 to 2 lines 

 thick. 



Under spruce and balsam trees. Essex, Lewis, Herkimer and 

 Onondaga counties. August and September. 



This pretty little agaric is liable to be mistaken for a species of 

 Naucoria, because of its peculiar colors, but its spores are white. 

 It is apparently closely related to T. cerinum, but the pileus of that 

 species is described as very dry, the flesh white and the stem 

 glabrous at the base, characters which are not well shown by our 

 plant. Because of its affinity to T. cerinum it has been placed in 

 the tribe Sericella notwithstanding its pileus is moist in wet 

 weather. 



Tricholoma infantile Pk. 



Infantile Tricholoma 



(Bulletin N. Y. State Mus., Vol. l, Number 2.) 



Pileus thin, convex or nearly plane, even, minutely silky, moist in 

 loet weather, reddish-gray, the marg-in at first incurved and whitish : 

 lamellae subdistant, plane or slightly ventricose, often eroded on the 

 edg-e, whitish; stem short, equal or tapering upward, hollow, 

 slightly silky, colored like the pileus or a little paler; spores 

 broadly elliptical, .0003 to .00035 in. long, .0002 to .00025 broad, 

 often containing a shining nucleus. 



Pileus 4 to 12 lines broad ; stem 1 to 1.5 in. long, 1 to 2 lines 

 thick. 



Gravelly soil in fields. Rensselaer county. June. 



This small species is apparently related to P. coelatum, from which 

 it is separated by its pileus which is not at all umbilicate, but on 

 the other hand is sometimes papillate. The stem is fleshy-fibrous 

 and hollow but its cavity is very small. In the larg-er specimens 

 the margin of the pileus is often wavy or irregular and the edge of 

 the lamellae eroded. This and the preceding species by being* 

 somewhat moist in wet weather form a transition to the next Series. 



Series B 



Pileus glabrous, either watery-spotted, moist or hygrophanous, 



not viscid, its flesh very thin or becoming soft or spongy; veil 



pruinose. 



Guttata 



Pileus fleshj^ soft, fragile, spotted as if by drops or rivulose ; stem 

 solid. Mostly vernal, growing in troops or csespitose. 

 No representative.
