11:124. 1895. — Coniophora alboflavescens (Ell. & Ev.) v. 
Hohn. & Litsch. К. Akad. Wiss. Wien Sitzungsber. 116 : 791. 
1907.—Coniophora Petersii v. Hohn. & Litsch. К. Akad. Wiss. 
Wien Sitzungsber. 117 : 1086. 1908, but not Corticium Petersu 
Berk. & Curtis. 
Type: type and cotype in Kew Herb. and Curtis Herb. 
Fructification effused, membranaceous, 
C О separable, drying pinkish buff, Ше margin 
white, cottony, often with radiating my- 
сепа] strands; hymenium even, pulveru- 
lent; in structure 400-1000 д thick, com- 
posed (1) of a supporting layer of very 
loosely interwoven, hyaline hyphae 21-3 
и in diameter, incrusted with scattered 
granules, and (2) of a compact hy- 
menium; no cystidia; spores slightly col- 
ored under the mieroseope, even or 
slightly rough, 6-8 415-6 y. 
Fructifications 1-15 em. long, 1-5 em. 
broad. 
"nm On prostrate fallen limbs and wood of 
C. polyporoidea. А 
Spores, hyphae, x 665. Various frondose and, more rarely, со- 
niferous species, and on bark at bases of 
trees. New Hampshire to Florida and westward to Michigan 
and Arkansas. June to March. 
This fine species has the color and surface texture of buck- 
skin leather and a distinctly white margin. The spores differ 
from those of other species of the genus in having so little 
color and in absorbing eosin stain so intensely that their orig- 
inal color is masked by the dye and the species likely to be 
mistaken for a Corticium. The roughish spores show rela- 
tionship to Hypochnus.
