however, as represented in Massee’s figure does not present 
the same peculiarities which appear to distinguish our species. 
Another small species from South Carolina was first described 
in 1857 by Berkeley as M. Ravenelii. It is smaller than the 
other two American forms, and further differs from them in 
the fact that its exoperidium often remains attached to the endo- 
peridium in the form of wart-like protuberances. 
Three American species may then be distinguished as fol-
