black, glabrous, siibspherical. Ostiolum papilliform. Asci clavate- 

 cylindrical, 75-100 x 15-18 fi, paraphysate. Sporidia crowded, linear- 

 lanceolate, yellowish, nucleate and uniseptate at first, iinally 5- or more- 

 septate, consti^cted and more or less swollen in the middle, 37-50 x 

 3i-5 fj.. 



On dead leaves of Mertensia, Utah (Jones). Closely allied to 

 L. Ogilviensis, but sporidia rather larger, and perithecia not col- 

 lapsing.

 Leptosphtsria Lophanthi^ Sacc. Syll. 3163.

Perithecia minute, covered by the cuticle. Asci oblong. Spo- 

 ridia fusiform, slightly curved, 6-septate, 50 [i long. 

 On Lophanthus, Pennsylvania (Micheuer). 



The specc. distributed under this name in Roum. F. Gall. 3954, 

 are some sterile, worthless thing and give no assistance.

Perithecia at length liberated, conical. Sporidia elongated, 

 acuminate at each end, with about 8 septa, the central joint swelling, 

 52 fx long.

Perithecia somewhat scattered, covered, not erumpent, obtusely 

 globulose, and papillate. Asci elongated-clavate, 120-130 x 16-18 n, 

 paraphysate, 8-spored. Sporidia subbiseriate, fusoid, straight or 

 curved, 35-38 x 6-7 //, yellowish-olive, 5- (rarely 7-) septate, slightly 

 constricted at the septa. 



On dead stems of Artemisia cana, Helena, Montana (Kelsey). 



The pycnidial stage, HenderSonia Artemisice, Sacc, was not 

 observed. This has erumpent-superficial perithecia of medium size 

 with cylindrical ostiola as long as the diameter of the perithecia, and 

 fusiform sporules 40 x 8 fi, 5-6-septate, yellowish and slightly con- 

 stricted at the septa. In the Montana specc. the sporidia are 20-26 x
