These two collections are, however, the small depauperate form which was origi- 

 nally named Polyporus sector, the most "prior" name.

Sydow, 3426 = Daedalea cervina (?) specimen poor (misdetermination). 

 The abundant tropical plant so common in Florida, which has mostly been re-

 brown. Is it not Trametes serialis ?
