finally flattened horizontally, narrow-elliptical, 1-1 J mm. long, with 

 the ends subacute; lips swollen, distinctly open, sides of the perithecia 

 rough and obscurely striate. Asci oblong-clavate, 100-150x25-35 jut, 

 subsessile, paraphysate. Sporidia irregularly crowded, oblong, mostly 

 a little curved, ends obtusely rounded, yellowish-hyaline, with a 

 gelatinous envelope at first, 1-2-septate and constricted at the septa, 

 60-70x12-15//. 



On dead twigs of Vitis, Carolina (Curtis), Louisiana (Langlois), 

 on Sabal serrulata, Florida (Martin). 



The above description of the species was made from the Louisi- 

 ana specc, which agree well with Duby's diagnosis in all but the pres- 

 ence of paraphyses. The sporidia are mostly uniseptate. 



G. ovata, (Cke.) 



Hysterium ovatum, Cke. Grev. XI, p. 107. 

 Gloniella ovata, Sacc. Syll. 5717. 

 Kxsicc. Rav. F. Am. 321. 



Perithecia gregarious, superficial, ovate, ends obtuse, black, longi- 

 tudinally striate, lips closed. Asci subcylindrical. Sporidia sub- 

 lanceolate, rounded at the ends, hyaline, 15-1 8 x 8 //, nucleate, finally 

 pseudo-triseptate. 



On old oak wood, Carolina (Ravenel). 



The spec, in Rav. F. Am. (the only one we have seen) is entirely 

 without fruit, so that we can only copy the published diagnosis. The 

 outward appearance is about the same as that of Glonium parvulum, 

 Ger. 



G. sycnophila, (Cke.) 



Hysterium {Gloniella) sycnophilum, Cke. Grev. XIV, p. 14. 

 Gloniella sycnophila, Sacc. Syll. 7385 (Add. I, p. 269), id. II, p. n 14. 



Perithecia gregarious, lanceolate, straight or flexuous, black, 

 emergent, with a narrow, longitudinal cleft. Asci subclavate, 8-spored, 

 Sporidia sublanceolate, multinucleate, finally 5-septate, hyaline, 36-40 

 x 8-10 jut. 



On bark of living fig trees, South Carolina (Ravenel). 



Specimens in our Herb, from Ravenel are apparently some species 

 of Opeyrapha. Asci oblong-clavate, 45-50x12 jul, subsessile. Spo- 

 ridia inordinate, fusoid, hyaline, 3-septate (pseudoseptate), 20x3-3| p.
