Perithecia scattered, lenticular, rather broadly pierced above, 

 prominent, but covered with the cuticle, their bases sunk in the matrix, 

 and more or less distinctly fringed with brown, branching mycelium. 

 Asci without paraphyses, clavate-cylindrical, with a short, narrow base, 

 80-90 X 18-20 fj.. Sporidia crowded, acutely elliptical, uniseptate and 

 constricted, upper cell mostly broader, smoky-hyaline, 20-28 x 8-12 ji.

 S. decidua, E. & K. Bull. Torr. Bot. Club, XI, p. 122. 



Perithecia visible on both sides of the leaf, of coarse, cellular 

 structure, depressed-globose, 100 ji diam. Asci oblong, sessile, 50 x 

 15 fi. Sporidia crowded or biseriate, oblong or oblong-pyrifbrm, uni- 

 septate and constricted, mostly a little curved, ] 1-12 x4-5 fi. Peri- 

 thecia in small (1-1 J mm.), round, dull-white, translucent spots with a 

 narrow, raised border; these spots are on dead, discolored parts of the 

 leaf, which finally fall out and leave irregularly shaped holes, as if the 

 leaf had been eaten out by insects.

 with the spots whiter and more confluent and mostly not on dead, but 

 on living, green parts of the leaf, Manhattan, Kansas (Kellerman).
