Tricholoma fumescens Pk. 



Smoky Tricholoma 



(N. Y. State Mus. Rep. 31, p. 32.) 



Pileus convex or expanded, dry, clothed with a very minute 

 appressed tomentum, whitish ; lamellse narrow, crowded, rounded 

 behind, whitish or pale cream color, changing to smoky-blue or 

 blackish where bruised; stem short, cylindrical, whitish; spores 

 oblong-elliptical, .0002 to .00025 in. long-. 



Pileus 1 in. broad ; stem 1 to 1.5 in. high, 2 to 3 lines thick. 



Woods. Columbia county. October. Rare. 



The species is remarkable for the smoky or blackish hue assumed 

 by the lamellae when bruised and also in drying. It is apparently 

 related to T. immundum Berk., but in that species the whole plant 

 becomes blackish when bruised, and the lamellae are marked with 

 transverse lines and tinged with pink. 



Tricholoma fuligineum Ph. 



Sooty Tricholoma 



(N. Y. state Mus. Rep. 41, p. 60.) 



Pileus convex or nearly plane, obtuse, often irregular, dry, 

 minutely squamulose, sooty-broion, flesh grayish, odor and taste 

 farinaceous; lamellae siibdistant, uneven on the edge, cinereous 

 becoming blackish in drying ; stem short, solid, equal, glabrous, 

 cinereous ; spores oblong-elliptical, .0003 in. long, .00016 broad. 



Pileus 1 to 2.5 in. broad ; stem 1 to 1.5 in. long-, 3 to 5 lines thick. 



Among mosses in open places. Greene county. September. 



Rare. 



Rigida 



Pileus rigid, in compact species hard and somewhat cartilaginous, 



in thinner species very fragile, the margin naked, the pellicle of the 



pileus rigid, punctate granulate, or broken up when dry into small 



smooth scales, neither viscid, floccose-scaly nor torn into fibrils. 



No representative. 



Sericella 



Pileus at first slightly silky, soon becoming glabrous, very dry, 

 neither moist, viscid, hygrophanous nor distinctly scaly, rather 

 thin, opaque, absorbing moisture, but the flesh of the same color as 

 the lamellae ; stem fleshy, fibrous. 



T. fallax and T. infantile are somewhat moist in wet weather, 

 but are placed in this group because of their manifest nearness to 

 species belonging to it. The same is true of T. albiflavidum.
