Fruetification effused, dry, at first flaxy 
and hypochnoid, at length compact at the 
disk, drying cream-color to Naples yellow, 
the margin flaxy ; hymenium even, tomen- 0 Q 
tose; in structure 150-350 и thick, com- 
posed of very loosely interwoven, rigid, 
nodose-septate hyphae 3-4 џ in diameter, 
which give the color to the fructification ; 
cystidia slender, tapering, sharp-pointed, 
non-incrusted hairs, frequently nodose- 
septate, concolorous with the hyphae, 
3-414 шіп diameter, emerging up to 20-60 
и; Spores concolorous with the hyphae 
but sometimes nearly hyaline under the 
microscope ,even, 4-444 214-3 и, perhaps - 
larger in spore collections. C. i 
Fructifications ranging from 1 to 6 em.  Hypha bearing cysti- 
in diameter, or perhaps larger. dimit es zr 
On wood and objects on the ground and 
running over the humus in pine woods. Canada to Louisiana

Jamaica; apparently very common in the northwest. June 
to December. 
If one does not overlook the pale color of the small spores, 
this species is easily recognized, for in Coniophora it is note- 
worthy among all species of the genus by its bright color—
