Eutypella herbicola E. & E. 



On dead stems of Aster cordifolius. Ohio. Morgan No. 1,122. 



Stroma elongated, 5 or more cm. long, and 2-3 mm. wide, slaty- 

 black outside, circumscribed by a black line which penetrates deeply 

 into the substance of the stem. Perithecia globose, 300-450 // diam. 

 not deeply buried, lying either singly or 3-10 together in valsoid 

 groups. Ostiola erumpent, tuberculo-globose or short- cylindrical 

 with their tips swollen, quadrisulcate. Asci, p. sp., fusoid-clavate, 

 30-35 x 5-6 ,"., with a slender stipe. Paraphyses obscure or none. 

 Sporidia allantoid, yellowish, slightly curved, obtuse, 6-8 x lf-2 //. 



Differs from E. cerviculata (Pers. ) in its partly scattered perithecia 

 and herbicolous growth, in which respect it approaches Cryptosphwria. 



Diatrypella Fraxini E. & E. 



On dead limbs of Fraxinus viridis. Rooks Co., Kansas, July, 

 1895. E. Bartholomew, No. 1,783. 



Stroma cortical and convex, 2-3 mm. diam., formed of the 

 slightly altered substance of the bark, without any distinct circum- 

 scribing line. Perithecia 8-12 in a stroma, globose, 250-300// 

 diam., ostiola united in a brownish-black, erumpent disk, only 

 slightly projecting, becoming 4-cleft. Asci clavate, 110x12//, 

 long-stipitate, paraphysate, polysporous. Sporidia crowded, allant- 

 oid, yellowish-hyaline, curved, 6—8 x lf-2//. 



The stromata raise the bark into distinct pustules, to the sides of 

 which the lobes of the ruptured epidermis closely adhere. 



Melogramma boreale E. & E. 



On bark of dead Abies, Newfoundland. Waghorue. 



Stromata gregarious, erumpent, bordered by the lacerated, up- 

 turned epidermis, suborbicular or irregular, 1-2 mm. diam., or by 

 confluence subflexuous, black, roughened above by the prominent, 

 obtuse ostiola. Perithecia buried in the stroma, not numerous. 

 Asci clavate-cylindrical, 75-80x12//, with a short stipe, paraphy- 

 sate, 8-spored. Sporidia biseriate, clavate-oblong or ovate-oblong, 

 uniseptate and constricted in the middle, each cell finally becoming 

 uniseptate, slightly narrowed toward each end, but not acute, 1*0- 

 13x3J-4i //.
