Fructifications coriaceous, soft, everywhere drying Naples- 

 yellow, losing the bright color in the herbarium; upper surface 

 sericeous, lineate-striate, the margin variable, 



n 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 

 ov lens; cystidia hair-like, not incrusted, cylindric, 

 obtuse, 6-8 m in diameter, protruding up to 40 m; 

 t' spores hyaline, even, 5-8X3-4 //. 



Fructifications 2-3 cm. high; pileus 1-2 cm. 

 in diameter when infundibuliform and 5 mm. -4 

 cm. when fiabellif orm ; stem 1 cm. long, about 

 1 mm. thick. 



On ground and dead wood. West Indies to Par- 

 aguay. June to February. Apparently frequent. 

 Fig. 2. S. aurantiacum is unique among the stipitate

 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-
