An original specimen of Persoon's Polyporiis perpusillus, pub- 

 lished by Leveille in 1844, shows this plant to be the same as 

 Trametes ohiensis Berk., published in 1872. Persoon's name, 

 therefore, must be adopted instead of the one under whicli the 

 species is commonly known. Considering the very small size of 

 the species, the older name seems exceedingly appropriate. 



To the above list of species should be added Fomes Auberianus 

 {Polyporus Auberiamts Mont. PI. Cell. Cuba 397. 1842), described 

 from Cuban plants collected by Auber. It is a large and striking 

 species found on wounded trunks or dead logs of hardwood trees 

 throughout tropical America. Material is at hand from Cuba,
