fasciatum and are not wedge-shaped and attached merely by 

 the umbo in any specimens which I have seen; the bleeding or 

 red-discoloration of the hymenium when cut or bruised and the 

 presence of colored conducting organs are additional characters 

 which separate S. australe from S. fasciatum. S. australe may 

 be distinguished from S. gausapatum by not having its reflexed 

 portion crisped nor consisting of small pilei which stand out near 

 together and in imbricate arrangement from a common resupi- 

 nate portion. 



In case of the collection from Mississippi, it was noted that the 

 substratum was badly sap-rotted. 



If original specimens of Thelephora mytilina, collected by Lund 

 in Brazil, are still in existence, I believe that they will be found 

 cospecific with S. australe. The geographical range of S. australe 

 and the description of T. mytilina favor this belief. Fries's de- 

 scription was probably based on dried specimens, and it does not 

 mention bleeding of the hymenium nor such a microscopical 

 character as colored conducting organs, for such a microscopic 

 detail was not noted in those days, but the blackening of the 

 edge of the pileus which was observed by Fries is an indication 

 of a bleeding hymenium and colored conducting organs.
