254 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
It is surprising that only the original collection of C. dryina 
has been made, for the two portions which are the type and 
собуре were apparently from a large conspicuous fructifica- 
tion. С. dryina has as distinguishing characters its thickness, 
snuff-brown color throughout, velvety surface, absence of cys- 
tidia, and stratose structure. 
Specimens examined: 
Alabama: Peters, 709, type and cotype (in Kew Herb. and 
Curtis Herb., 5204, respectively).

Type: in Coll. N. Y. State. 
Fructification effused, indeterminate, 
membranaceous, not fleshy, somewhat 
separable when thick, drying from avel- 
laneous to tawny olive and Saccardo’s 
umber, the under side and margin 
usually whitish and mucedinous; hy- 
menium even; in structure 60-500 д

nodose-septate; по cystidia ог with 
cystidia barely distinguishable from immature basidia; spores 
snuff-brown in a spore collection, even, 10-12 6-7 и. 
Fructification 2-9 em. long, 1-5 em. broad. 
Common on under side of coniferous boards and limbs lying 
on the ground, rare on frondose species. Canada to Louisi- 
ana and westward to Vancouver Island and Washington. May 
to January. 
This species bears some resemblance to C. cerebella and 
C. arida, approaching the former in its separable tendency 
when thick and the latter in general habit, coloration, dry 
structure, and loose arrangement of its hyphae. It is distin-
