 Fung. 168. 1828; Schweinitz, Am. Phil. Soc. Trans. N. S. 4:

Type : in Herb. Schweinitz, Acad. Nat. Sci. Phila. 



Fructifications cespitose, erect, coriaceous-soft, white, dry- 

 ing warm buff, stipitate ; stem thick, palmately branched, with 

 branches spreading, branching, cylindric or subcylindric ; 

 hymenium inferior on the main branches, often amphigenous 

 on secondary branches; basidia longitudinally septate, 10- 

 12 X 7^9 ji ; spores colorless, simple, even, 7|-10 X 4^-5^ /x. 



Fructifications 2|-5 cm. high, 2-5 cm. broad ; stem 2-10 mm. 

 thick ; smaller pileate branches about 1| mm. thick. 



On ground in open woods. Vermont to North Carolina and 

 westward to Missouri. July to September. Infrequent. 



The type of T. candidum has the dimensions given above 

 for recent collections. In the original description Schweinitz 

 noted that fructifications may attain a breadth of 15 cm. ; at 

 that time he had not given specific recognition to the large 

 and common T. pallidum and it may be that the large speci- 

 mens to which he referred were of the latter species. T. candi- 

 dum is closely related to T. pallidum but contrasts with the 

 latter in having consolidation between adjacent fructifications
