BURT THELEPHORACEAE OF NORTH AMERICA. VIII 251 



The northern specimens cited below have the approximate 

 spore characters of C. sistotremoides but an even hymenium, 

 hence they are all referred with doubt to this species for the 

 present. Possibly the granular condition of this species may 

 be confined to the vicinity of North Carolina.

 colored, and its spores are colored, shorter, broader, and 

 almost mucronate-pointed.
