BURT THELEPHORACEAE OF NORTH AMERICA. XII 91 



On the ground, rarely on wood humus. South Carolina to 

 Mexico, West Indies, and Brazil. July to April. 



S, Ravenelii is near S. pergamenum in microscopic characters 

 but is constantly infundibuliform, with slender, more conspic- 

 uous stem, and occurs on the ground except very rarely, and 

 is gregarious rather than cespitose. The range of S. Ravenelii 

 southward to Brazil is so much greater than has been noted 

 heretofore that it would be well to compare with it authentic 

 specimens of some of the imperfectly described South American 

 species of central-stemmed Stereums
