Always single and simple, gregarious, 1.3-2.4 cm. tall, stem 

 as long as or longer than the club from which it is distinct in 

 smaller size, more translucent color and much tougher texture; 

 club terete, nearly cylindrical, brittle but not very fragile, about 

 1-1.4 mm. thick, bluntly pointed, pale whitish cream or greenish 

 cream, the tips concolorous in youth then yellowish then reddish ; 

 stalk slender, flexible, glabrous except above, where it is pruinose, 

 quite tough, pale creamy flesh color, the base often distinctly sur- 

 rounded by a little boot or spreading pad of white mycelium; 

 tasteless and odorless. In drying the plants become dark car- 

 tilaginous in color and appearance, and frequently the tips can 

 be seen to be less shrunken, taking the shape of a little cap. 



Spores (of No. 2806) white, elliptic, with a small eccentric 

 mucro, smooth but often granular with the appearance of being 

 punctate, when quite fresh only a few with an oil drop, 

 3.7-4.4 x 5.2-7.5(1., most about 4 x 6[/.. Basidia 4-spored, 4.8-5.5 x
