 edge entire. Stem 2-3 cm. long, 1.5-3 mm, thick, equal, solid, 

 innately and longitudinally silky-fibrillose, white scarcely chang- 

 ing, subshining when dry. Cortina slight and evanescent, per- 

 haps lacking. Odor and taste subfarinaceous. Spores 7-9 x 

 4-5 jJL, narrowly elliptic to oblong, hyaline, smooth, granular

In size, habit and appearance this resembles an Inocybe. 

 It differs from T. iriste Fr. in its solid stem and indistinct cor- 

 tina, and probably in its spores.
