Perithecia buried in the substance of the leal' and visible on both 

 sides, but more prominent above, evenly scattered or in small groups 

 with scattering perilheria intermediate, globose, 100-115 // diam.. 

 with a broad, round opening above. Asei oblong, 50-55 x 10-12 /;. 

 \vithout paraphyses, Sporidia crowded, oblong-fusoid, subinequi- 

 lateral, nniseptate and mostly constricted at the septum, hyaline, 

 14-16 x 4 //. This is quite different from Sphcerella Maydis, Pass., 

 \vhich has rather larger perithecia more distinctly grouped, and (sec. 

 specc. in Rab. Fungi Europasi, No. 1851) sporidia fusoid, 16-20 // 

 long. It is also different from S. Muhlenbergice, Ell., which, by 

 the way, is a good species and quite distinct from either S. gramin- 

 icohi, Fckl., which has larger asci and sporidia, or S. pusilla, Aw<L 

 S. yraminicola, Fckl., (sec. specc. in Rehm's Ascom., 794, and F. Eur. 

 3446) has asci 75x12 p, and sporidia 15-20 x 3|-4| /*.

 curved, 15-20x5-6 /*. 



On languishing leaves of Zizania aquatica, Delaware (Commons), 



The specimens of Sphceria Zizanice, Schw., in Herb. Schw., are 

 sterile and poor, but the Delaware specimens appear to be that species.

 S. galla, E. & E. Bull. Ton*. Bot. Club, XI, p. 75. 



Perithecia minute, scattered or 2-3 together, rupturing and
