 90 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



On wood on the ground. Venezuela, British Guiana, and 

 Brazil. November. 



This South American species ranges so far to the north that it 

 may possibly occur also in the West Indies or Central America. 

 The fructifications have dimensions and general aspect of those 

 of S. caperatum but are distinguishable by darker color of pileus, 

 stem and hymenium, by velvety covering of pileus and stem, 

 and by absence of elevated longitudinal ridges on the surface of 

 the pileus.
