Fructifications coriaceous, soft, everywhere drying Naples- 
yellow, losing the bright color in the herbarium; upper surface 
sericeous, lineate-striate, the margin variable, 
often somewhat fimbriate; stem thin, with yel- 
lowish tomentum at the base and sometimes with 
tomentose mycelial strands; hymenium even, or 
nearly so, setulose with hyaline hairs under a 
Q lens; cystidia hair-like, not incrusted, cylindric, 
obtuse, 6-8 uy in diameter, protruding up to 40 y; 
spores hyaline, even, 5-8X 3-4 y. 
Fructifications 2-3 cm. high; pileus 1-2 cm. 
in diameter when infundibuliform and 5 mm.-4 
cm. when flabelliform; stem 1 cm. long, about 
1 mm. thick. 
On ground and dead wood. West Indies to Par- 
aguay. Juneto February. Apparently frequent. 
Fig. 2. S. aurantiacum is unique among the stipitate 
S. aurantiacum. — Stereums by its bright yellow color. Lloyd states 
ka sche ce that old specimens may lose their bright yellow 
x 665. color and become brown, and the figures by Mon- 
tagne indicate this also. I have seen only one 
gathering in which some of the specimens have discolored brown- 
ish; this gathering from Porto Rico, by Prof. Stevenson, bears 
the field note: “nearly pure white when collected; became yellow 
in drying; no yellow showed until partly dried." The extensive 
synonymy of this species is due to its occurrence sometimes on 
the ground, sometimes on wood, sometimes being wholly infundi-
