 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 m thick, composed of a broad 

 layer of densely and longitudinally arranged, thick-walled, 

 hyaline hyphae 3 m in diameter and of a hymenial layer 45-90 /* 

 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 

 M long, with ventricose base 6-9 m in diameter, sometimes barely 

 emergent above the basidia; spores hyaline, even, 3-4X2-3 m. 



Fructifications l§-4 cm. high, 1-2| cm. in diameter; stem 

 3-7 mm. long, about 1^ 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 L^veille 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- 

 nitens. 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 and run at right angles to the latter.
