fruit-bodies, the host must have been the small dead or dying 
branches of some broad-leaved tree. 
6. Inonotus corrosus sp. nov. 
Pileus conchate, clasping, simple or imbricate, 3x 5 x I—4 cm.; 
surface ferruginous to fulvous, furrowed and much corroded in age ; 
_margin entire, obtuse, tomentose, honey-yellow: context thick, 
spongy, fibrous, ferruginous, perforated by insects soon after ma- 
turity ; tubes very short, only 1 mm. long each season, 8 to a 
mm., fulvous, subcylindrical, edges entire, obtuse to acute ; spores 
lenticular, smooth, pale ferruginous, 4 in diameter, 1 » thick, 
hyphae deep ferruginous. 
The type plants of this species were collected by Earle, xo. 
203, near Hope Gardens, Jamaica, October 27, 1902. They 
grew upon a dead vine clinging to a tree. Two or three years 
growth were represented in the much weathered and wormeaten 
central parts of the sporophores, while the latest growths stood 
out in marked contrast. The flattened appearance of the spores 
may be due to desiccation, but this character is fairly constant. A 
single sporophore of this species was also collected in the island 
of New Providence by Britton, zo. 246, Aug. 24, 1904, growing 
on a small dead twig. 
What appear to be specimens of this same plant are placed at 
Kew under Polyporus chrysites Berk., a species described from the 
region of the Rio Negro river in Brazil as thin and leathery, while 
the various plants bearing that name at Kew are mostly thick and 
soft or even hard and perennial. Specimens collected in Cuba by 
Wright should probably belong to /. corrosus instead of to P. 
chrysites. 
7. Inonotus Wilsonii sp. nov. 
Pileus dimidiate, applanate, sessile, 2-3 x 4-6 x 0.5 cm. ; sur- 
face anoderm, velvety-tomentose, fulvous, marked with a few 
shallow concentric furrows; margin thin, entire, concolorous, 
sulcate, deflexed in drying : context soft, punky, homogeneous, 
ferruginous-fulvous, 1-3 mm. thick, separated from the tubes by a 
very thin black layer; hymenium ferruginous, glistening, tubes 
1-2 mm. long, 6-9 to a mm., isabelline within, mouths polygonal, 
regular, edges thin, entire ; spores lenticular, smooth, pale ferrug- 
inous, 3—4 # in diameter, 1—1.5 y thick. 
This species was collected by Percy Wilson, xo. 438, on decay-
