Plates 60 and 88 



Gregarious, often crowded, broom-like, slender and delicate 

 throughout, much and closely branched from the base or with a 

 short stalk, 2-6 cm. high, about 2-4 cm. broad, tips slender and 

 sharp, numerous, open but scarcely divaricating; surface smooth, 

 not pubescent below except for the mycelium in protected places ; 

 color a pale leather-tan, the base darker leather color, the tips 

 nearly white; when dry becoming a very even and distinctive 

 umber brown (about drab or buffy drab), and often with an olive 

 tint, particularly upward. Flesh not brittle, but bending on self 

 without breaking, odorless and tasteless, not changing color when 

 bruised; when dry very brittle and delicate. Mycelium white, 

 farinose-flocculent, delicate and abundant, scarcely stringy, con- 

 spicuous in the leaves or humus. 



Spores (of B. No. 781) very hyaline (white?), narrow, 

 subelliptic, sigmoid, smooth, 2.2 x 7A-7.7[k; basidia about 5a thick, 

 4-spored. Hymenium (of C. & B. No. 101a) simple, without em- 

 bedded spores and very few on the surface, 48-5 5 [i. thick. 



This interesting species is evidently rare. We have it only 

 from Pennsylvania and from Vaughns, N. Y., where it has been 

 found by Mr. Burnham in two old groves of deciduous trees where 

 it occurs from year to year, and by us in pure hemlock leaves 

 under hemlock. Mr. Burnham says, "The plants usually spring 

 from the old humus of decaying leaves of several years, with more 

 or less decaying twigs mixed with the vegetable mold: some of 

 the plants (of No. 78) were found growing on rotten wood; so 

 that the plants are not wholly dependent on decaying leaves for 



habitat." 



From C. flaccida and C. subdecurrens which are nearest in size 

 and habit and with which it may be associated the species is 

 separated by the lighter color when fresh, the quite different color
