GARDEN 



In long grass in woods and pastures. 



Cotton and Wakefield comment further: 'This species is very 

 distinct in its beautiful ivory-white color and loosely branched 

 habit. When well grown, it may form tufts 4 to 5 inches high 

 and as much across, but average plants are decidedly smaller. 

 From C. rugosa it is distinguished by being branched from the 

 base and by the slender, even (not rugose) branches, and from 

 C. cristata by the loose habit, lunate axils, and non-cristate 

 branches. From both it differs in very small spores." 



In gatherings in frondose woods among leaves from Vermont, 

 New York, and Michigan, which I have studied, the spores are 

 only about 3 m in diameter.

"Plants very much branched dichotomously, curved and some- 

 times deformed, white to alutaceous, terminal branches rose pink, 

 or yellowish brown probably when old. Basidia 4-spored. Spores 

 obovate, asperulate, white, 3-4x2-3 p.— C. U. herb., No. 13647, 

 ground, woods north of Varna, N. Y. Whetzel, Aug. 21, 1902." 



Fructification now between antique brown and cinnamon- 

 brown, with trunk and main branches pinkish buff; branches 

 not crowded, of rather uniform diameter; spores hyaline, mostly 

 even — only very rarely by prolonged search may one be found 

 obscurely asperulate — subglobose, 4-4 1 / 2 X3 1 /2-4 p. 



This seems very near C. Kunzei

"Forming dense tufts 7.5-12.5 cm. tall, fragile, white or 

 whitish, the stems united at the base, three to five times dichot- 

 omously divided, the terminal branchlets obtuse or subacute, 

 both stems and branches solid, soft, becoming thinner and flat- 

 tened or angular in drying, flesh white, taste mild; spores broadly 

 ellipsoid or subglobose, 4-5X3-4 u.
