Dear Guido;-
        I think you have made the qualifying statement: "If it is different
enough!"
        Perhaps the standard should be: "If it is found to be unlike anything
else."
        I think the ones we object to are species that COULD be freaks of
something else, or should be listed as geographic "Forms", or (at the
outside limit) Sub-species. We keep getting species described as
diferent when, on a little reflection, they turn out to be C. dingdong
(with a hangnail).
        For me the problem continues to be a proliferation of descriptions for
the same species. Paschall counted over 20 descriptions and names for E.
lamellosum. AND THE NAMES NEVER DISAPPEAR! So eventually a dealer will
advertise: JUST DISCOVERED! The genuine C. hangnail!!
