Perithecia subulate, stylosporiferous at base, and with a medial 

 or snbapical enlargement above, containing the ascigerous nucleus. 

 This latter character will distinguish this genus from Gcrdtoxtomu, 

 CW/''/o/As-/.x\ Pk. is also closely allied, but is placed by its author among 

 the D iscomycetes.

Ravenel's specimens are on poplar bark. Mr. C. J. Sprague has 

 sent specimens collected by W. N. Suksdorf in Washington, and 

 which agree in all respects with Ravenel's specimens. Suksdorf s 

 specimens are also, apparently, on bark of poplar.
