BURT—THELEPHORACEAE OF NORTH AMERICA VI 219 
Type: in Coll. N. Y. State. 
Fructification effused, thin, membranaceous, separable 
from the substratum, granular, sepia, the margin somewhat 
radiate, concolorous or nearly so; in struc- 
ture 200—400, thick, composed of very loosely e 
interwoven, thin-walled, occasionally nodose- E 
septate, hyphae 214-4» in diameter, yellow- e са 
ish under the microscope, forming near the 
substratum some rope-like mycelial strands H. granulosus. 
up to 15и in diameter; spores concolorous Spore, hyphal 
; strand x 640. 
with the hyphae, angular-subglobose, acule- 
ate, the body about 64 in diameter; KHO solution produces 
no noteworthy color change in sections. 
Fructifications 2-4 em. long, 1-2 em. broad. 
On rotten bark and wood of frondose species. Massachu- 
setts to New Jersey and Ohio. September to November. 
Rare. 
H. granulosus is very closely related to H. coriarius and 
is distinguished from it by uniform color of the whole sur- 
face, while H. coriarius has the margin ochraceous-tawny. 
The lack of noteworthy color change by KHO solution is the 
only additional feature of difference for separating H. gran- 
ulosus from H. coriarius. The specific name tabacina of 
Cooke and Ellis has priority, but is not now available be- 
cause Bresadola has already used the name Hypochnus ta- 
bacinus for a valid species. 
Specimens examined: 
Exsiceati: Ellis, N. Am. Fungi, 421, under the name Zygo- 
desmus chlorochaites. 
Hungary: A. Kmet, authentic specimen of H. elaeodes from 
Bresadola, probably a portion of the type. 
Massachusetts: Newton, W. G. Farlow; Mt. Tom, H. W. 
Harkness, type (in Coll. N. Y. State). 
New York: Albany, H. D. House & J. Rubinger (in Mo. 
Bot. Gard. Herb, 8733); Karner, H. D. House (in Mo. 
Bot. Gard. Herb., 44731); Alcove, С. L. Shear, 1316, in
