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.
