Branching from the ground into clustered and often fused 

 stalks of variable length. Individual tufts delicate, slender 

 throughout, about 2-6 cm. tall, and 1.5 cm. broad, usually; at 

 times up to 9 cm. high and 6 cm. broad; branching quickly or 

 tardily into several branches which curve outward at base, mak- 

 ing broad, more or less lunate angles, then upright again, and 

 branching about twice more into two or three branchlets, which 

 terminate in rather abruptly pointed prong-like tips; main stems 

 and usually the lower parts of the main branches often decidedly 

 rough pubescent, with sterile, scurfy-velvety lines and areas ex- 

 tending higher up the plant in most cases, but often this pubes- 

 cence is practically absent; entire plant pure milk white, but in 

 drying the plant turns a tan or buff brown, the upper parts usually 

 becoming: reddish translucent like cartilage, or less often a deep 

 opaque brown; flesh white, toughish, not brittle, but soft and 

 flexible; cells of flesh closely packed, parallel, somewhat sinuous, 

 about 4-5 [i. thick; taste and odor none. Sometimes the main and 

 secondary divisions broaden before branching and rather resemble 

 the horns of an elk. There is much variation in the extent of the 

 sterile areas, some of the plants showing them over most of the 

 middle region, others having very few of them. All parts are 

 typically slender, but there is great variation in this respect, at 

 times the branches and stems are so numerous and delicate as to 

 almost resemble a Typhula when dried; again they are few and 

 much coarser. 



Spores white, spherical, minutely asperulate (under oil immer- 

 sion) or some apparently smooth, 2.5-3.5 x 3.5-4.5;j.. Hymenium 

 (of No. 4683) 55-65|x thick, apparently 2-layered; basidia about 

 4-6fj. thick, 4-spored. 



Gregarious on soil, rotting bark, or moss in moist deciduous 

 woods, rarely in coniferous woods. Miss Hibbard, as well as
