No attempt has hitherto succeeded to subdivide the overgrown
genus Sphoeria. My own proposed genera of Stroma-
tosphoeria, Cryptosphoeria, and also Ciicurhitaria, I am now
fully convinced cannot be sustained, and they will be erazed
in the synopsis of species with which I shall shortly terminate
this work. My able friend M. F r i e s has, however, proposed
a subdivision in his last work, upon better principles ; and if
the boundaries of his genera prove, upon application, sufficiently
defined, a great step will be obtained in our knowledge of
these plants.
