Ridgway. Flesh white, only up to 1 era. thick at stem, very thin 

 toward margin, pliable, taste mild and sweetish, odor faint. 



Gills crowded, very narrow, hardly up to 2 mm. wide, fading to 

 a line toward the stem and barely reaching it; color exactly that of 

 the cap. 



Stem 2-4.5 cm. long, 1.3-1.8 cm. thick, color and surface of cap, 

 solid, soft and pliable, the base sub-bulbous. 



Spores white, smooth, sub-elliptic to pip-shaped, 2.2-3 x 4-5ju,. 



A peculiar plant, sharply marked by the uniform gray-buff color, 

 soft, tough flesh and peculiar gills. In the absence of young stages 

 and with only one collection we prefer not to name it as yet. It may 

 possibly be a form of C. nebularis, but a plant of that species from 

 Peek has gills broader and much darker in the dried state. It can- 

 not be C. geotropa. In his Funghi Mangerecci, pi. 39, Bresadola 

 shows an obviously different plant and the spores are nearly globose 

 and rough. A plant from his herbarium, so labelled, has spores that 

 are rough, but they are 3.7-4.6 x 5-7/u, and are not like those of our 

 plant. Ricken gives the spores at 5-6 x 6-7;u, and does not mention 

 roughness. Clitocyhe geotropa is also recognized as being a paler 

 plant than ours and as being umbona+e or gibbous and it could hardly 

 be brought to the thinness in center shown by No. 3210. (See Bresa- 

 dola as cited above ; Ricken, pi. 101, fig. 1 ; Bulliard, pi. 573 ; and 

 Dumee, Atlas Champ., Ser. 2, pi, 15). Clitocyhe lenticulosa Gill, is 

 also easily different, with its rough cap and white, long decurrent gills 

 (Champ. Fr., p. 144, pi. 130).
