ing buckthorn-brown; in structure 200-300 y thick, with a 
broad, compact intermediate layer of longitudinally arranged, 
colored hyphae 2-21 u in diameter, which is connected with 
the velvety covering of the upper surface of the pileus by a 
narrow, dark zone; setae very few, tapering from the base, 
30x5-6 д, emerging 10-20 и above the hymenium; spores 
hyaline, even, 44424 д. 
Fruetifieations 14-24 em. long, 2-4 em. broad; resupinate 
portion of reflexed specimens may be up to 3 x 2 em. in speci- 
mens seen so far. 
On rotting trunks of frondose species. Porto Rico to Vene- 
zuela and Guiana. May. Probably common. 
H. luteo-badia is a beautiful tropical species which is well 
characterized by its name, for the contrast in color between 
the buckthorn-brown or tawny olive hymenium and the Argus- 
brown (chestnut color) upper surface of the pileus is a con- 
stant and distinguishing character; setae are as few and far 
apart in Ше hymenium as they are in H. Curtisii; the absence 
of a dark subhymenial zone bordering the hyphal layer is an 
additional character which separates H. luteo-badia from 
many other species of Hymenochaete.
