ated at the base, compressed, rather glabrous, very tough, paUid ; 

 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 T. 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 3-3^ 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 6m.

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 a common base and grow together above to form'a 

 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 papillose, yel- 

 lowish pallid becoming avellaneous or somewhat fuscous; 

 spores olive-buff under the microscope, bluntly angular (i. e., 

 tips of the angles obtuse), 4^-7 x 4|-5At. 



Fructification 2§-5 or 6 cm. high, 2f-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,
