specimens it is nearly or quite black. The cuticle is separable 



from the white flesh beneath. The flesh has no decided odor, and 



its taste is sometimes acrid and sometimes mild. The gills are 



rather broad but close, rounded behind and slightly attached 



to the stem. They are white, but are apt to become dingy or 



brownish in drying. The stem is rather long, equal, smooth or 



slightly fibrillose, solid, or hollow from the erosion of insect 



larvae and white. 



The cap is 1.5-3 inches broad; the stem 2-4 inches long, 3-6 



lines thick. The species is so closely related to the European 



virgate tricholoma, Tricholoma virgatum, that it is with 



some hesitation that I have kept it distinct. In the virgate 



tricholoma the taste is described as bitter, intensely bitter or 



bitter in the young plant and more mild in the mature one, the 



umbo is represented as low, broad and blunt and the cuticle on 



it as breaking up and forming scales. The stem is described 



and figured as more or less bulbous. These characters are not 



found in our plant, and their absence seems Ao justify its 



separation.

ROOTED TRICHOLOMA 



PLATE 82, FIG. 15-19 



Pileus fleshy, deeply or broadly convex, dry, silky fibrillose or 

 minutely squamulose, grayish brown, the center darker and often 

 tinged with reddish brown, flesh white, taste disagreeable; 

 lamellae thin, close, emarginate, adnexed, white; stem equal or 

 nearly so, radicating, hollow, white; spores broadly elliptic or 

 subglobose. .0002-.00024 of an inch long, .00016-.0002 broad. 



The rooted tricholoma is a rare species with us. It occurs 

 under spruce, balsam fir and other cone bearing trees in North 

 Elba, and is solitary or scattered in its mode of growth. It 

 was found in September and is apparently an autumnal species. 

 Its cap is broadly convex when mature, but in immature plants 

 it is similar in shape to an open umbrella. It is firm but flexible, 

 and its cuticle is separable from the white flesh. The surface is 

 dry, minutely silky and sometimes roughened with minute scales. 

 Its color is gray or grayish brown, generally a little darker in 

 the contfM-. whero it is tinged with reddish brown. The flesh is
