Of these those in black-faced type are here described for the first 

 time. 



Beside these unique forms, we report many species from our 

 region that have not been before credited to the flora of North Amer- 

 ica, include many hitherto unpublished asci and spore measurements 

 of species otherwise well described, and have transferred many not 

 before well understood to their proper genera. 



The host plants have proven also to be of special interest in that 

 many of them yield certain species for the first time in the mycologic 

 literature of this country, and many others pose as altogether new to 

 Host Indices. 



THE SYLVA. 



The State is very happily located for the growth of forests, be- 

 ing in the favored belt of temperature between about 37 and 

 41 north latitude. Within its boundaries trending northeast 

 and southwest, thus opening the country to the damp, warm winds 

 from the Gulf, are numerous ranges of the great Appalachian, or 

 Atlantic highlands, but by far the larger portion of the State lies on 

 the westward slope of these mountains in the trans-Appalachian belt, 

 the waters of which chiefly run northwestward and southwestward to 

 the Ohio River. The altitude of the country descends from the Back- 

 bone or Alleghany range of the Appalachians, from an altitude of
