Perithecia subulate, stylosporiferous at base, and with a medial 

 or subapical enlargement above, containing the ascigerous nucleus. 

 This latter character will distinguish this genus from G erdtostotna. 

 Galiciopti/'s, Pk. is also closely allied, but is placed by its author among 

 the Discomycetes.

Perithecia subcylindiical, about \\ mm. high and 100 /./ thick, 

 only slightly enlarged at base, and containing subglobose, continuous, 

 brown stylospores 3-5 // diam., or oblong-ovate, 5-10 x 4-5 ji and 2-3-

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

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

 which agree jn all respects with Ravenel's specimens. Suksdorfs 

 specimens are also, apparently, on bark of poplar.
