ated at the base, compressed, rather glabrous, very tough, pallid; 
pileus membranaceous-cartilaginous, when dry quite rigid, 
radiately rugose, with the ridges elevated towards the undulate 
and at first fimbriate margin, not zonate after the manner of 
species of Stereum; hymenium inferior, hardened. Related to 
Cladoderris. 
I refer to Т. cornucopioides a collection made in Jamaica by 
Prof. F. S. Earle, in 1902, the specimens of which agree well 
with the original description, as translated above, except in size. 
They are 3-34 cm. high and 2 cm. broad with stem about 1 cm. 
long by 2-4 mm. thick. The dried fructification is very hard 
and stony and softens so little with water that the edge of the 
razor is turned in sectioning. The spores are colorless and even 
at first and become slightly colored and angular, 9-10 x би.

Type: in Herb. Schweinitz. 
Fructification coriaceous, dirty whitish or pallid, sometimes 
wood-brown at the center, upper surface usually radiately pli- 
cate or rough with masses of agglutinated fibers; pileus polymor- 
phic, sometimes composed of ascending lobes or small pilei which 
arise from а common base and grow together above to forma 
broad cup, or sometimes with the whole interior of the cup filled 
with small pilei and lobes many of which arise proliferously 
from the upper surface of the outer lobes; stem central when 
present; hymenium inferior, rugose, somewhat рарШове, yel- 
lowish pallid becoming avellaneous or somewhat fuscous; 
spores olive-buff under the microscope, bluntly angular (i. e., 
tips of the angles obtuse), 43-7 x 43-би. 
Fructification 23—5 or 6 em. high, 21-7 cm. broad. 
On ground in frondose woods. Vermont to South Carolina 
and west to Illinois. September. 
This is a fine, large species well marked by the dirty whitish or 
yellowish, fibrillose upper surface of the pileus, thick substance 
of the same color unless the specimen is old, and the brown,
