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 T'helephora mytilina, collected by Lund 
in Brazil, are still in existence, I believe that they will be found 
cospecifie 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.
