92 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Pileus coriaceous, infundibuliform, sometimes more elongated 
on one side, glabrous, shining, lineate or striate, drying tawny to 
hazel, faintly zonate with numerous very narrow zones; stem 
central or eccentric, cylindric, drying avellaneous to burnt 
umber, fibrillose to minutely tomentose, attached at the base 
by a mycelial pad; hymenium glabrous, even, avellaneous to 
cinnamon; pileus in section 400 u thick, composed of a broad 
layer of densely and longitudinally arranged, thick-walled, 
hyaline hyphae 3 u in diameter and of a hymenial layer 45-90 y 
thick, the subhymenial portion of which may become thicker 
than the palisade layer of basidia and gloeocystidia and appears 
granular and composed of very fine hyphae; gloeocystidia 15-30 
x long, with ventricose base 6-9 u in diameter, sometimes barely 
emergent above the basidia; spores hyaline, even, 3-4 X 2-3 u. 
Fructifications 13-4 em. high, 1-23 cm. in diameter; stem 
3-7 mm. long, about 13 mm. in diameter. 
On dead wood. West Indies, Honduras, and Dutch Guiana. 
November. 
Lloyd's account and figures have made possible the reference 
to S. surinamense of the collections cited below, for the original 
description by Léveillé is fragmentary and does not even note 
whether the specimens were growing on the ground or on wood. 
I have not seen the types of either S. surinamense or S. fulvo- 
nilens. The specimens cited below are characterized by the 
attachment to the wood by a conspicuous mycelial pad, by 
rich hazel and shining upper surface of the large, narrowly 
zonate pileus, by the gloeocystidia, and by the minutely granular 
subhymenial region in which the hyphae are much finer than in 
the main hyphal layer —- run at right angles to the latter.
