BURT—THELEPHORACEAE OF NORTH AMERICA. X 311 
brown (3); in structure 600 џ thick, composed of a setigerous 
layer 90 џ broad and of a hyphal layer 500 џ broad, having 
densely arranged, colored hyphae 4j 
p in diameter, running longitudinally, 
eurving on the one side into the À 
hymenium and on the other into the =- 
surface of the pileus; setae ventricose `` 
at base, 1843-5 и, densely crowded — М“ 
together in all parts of the broad Fig. 1 
ЕРЕН layer; е hyaline, Section x 68. From type. 
even, 4X3 и. 
Fructifications 34 em. broad, 3 em. long. 
On dead wood. Jamaica, Cuba, and Venezuela. July. Rare. 
By the kindness of Sir David Prain, I have been able to 
study a portion of the type of H. Cacao collected in the Khasia 
Mountains, India; it has the hymenium olive-drab now but is 
of the same form and structure as American specimens. The 
American specimens are a rich tobacco-brown with darker 
hymenium. This species is noteworthy by having the setae 
densely crowded together through a zone 90 д broad. The 
collection by Earle, 406, cited below, seems referable to H. 
Cacao on account of the color of the hymenium and structure 
in section but it is wholly resupinate. 
Specimens examined: 
India: Khasia Mts., Dr. Hooker, portion of type comm. by 
Sir David Prain (in Mo. Bot. Gard. Herb., 55559). 
Jamaica: Cinchona, F. S. Earle, 406, comm. by N. Y. Bot. 
Gard. Herb., and W. J. Robinson (in N. Y. Bot. Gard. Herb., 
and in Mo. Bot. Gard. Herb., 55481). 
Cuba: C. Wright, 526 (1n Curtis Herb.). 
Venezuela: Fendler (in Curtis Herb.).
