Epiphyllous, scattered. Perithecia minute, globose, subprominent, 

 black, covered by the epidermis. Ostiolum papillate, perforated. 

 Asci clavate. Sporidia narrow, cylindric-elliptical, obtuse at the ends, 

 uniseptate, scarcely constricted, hyaline, 13-17 x3 /x.

' Exsicc. Ell. N, A. F. 1352. 



Perithecia erumpent, minute, generally elongated-seriate. Asci 

 oblong, 35 X 8-10 fj.. Sporidia biseriate, elliptical, uniseptate, 11-15 x 

 3-3| ij.. Stylospores in larger perithecia, 13-19 x 4 // {Phoma). 



On leaves of Muhlenhergia, Newfield, N. J. 



This and the preceding species, published about the same time, 

 may be the same, but we have no specc. of Cooke's species for com- 

 parison. 



S. Califdmica, Cke. & Hark. Journ. Bot. 1883, p. 136. 



Perithecia small, scattered, subspherical, innate-prominent, dark 

 brown, perforated above. Asci clavate-cylindrical. Sporidia narrow- 

 elliptical, uniseptate, hyaline, not constricted, 8 x 2 /i. 



On leaves of some native grass. 



On specimens in our Herb, sent by Dr. Harkness as Sphcerella 

 Californica, we find only a Septoria with perithecia 75-110 n diam., 

 and sporules cylindrical, curved, hyaline, continuous, 12-14x1^ /i. 

 Cooke (1. c.) is inclined to regard this as the mature state of Lcestadia 

 perpusilla, Sacc. 



S. Spartinse, E. & E. Journ. Mycol. IV, p. 97. 



Perithecia of coarse, cellular structure, subastomous, elliptical, 

 100-112 X 170-190 [1, buried in the parenchyma of the leaf, but plainly 

 visible above or on the outside, and faintly so below, quite evenly and 

 thickly scattered. Asci mostly immature in the specc. examined, but 

 evidently present. Free sporidia (which we believe to be ascospores) 

 oblong-elliptical, yellowish, constricted and faintly uniseptate in the 

 middle, with about 4 small nuclei, 12-]6x4|-5| fi. This can not be 

 the Ascochyta SpartincB, Trelease, Journ. Mycol. I, p. 14, on account 

 of the absence of any spots and the quite different sporidia. We are 

 also confident- that the Nebraska specc. are ascigerous. 



On dead leaves and sheaths of Spartina cynosuroides, Nebraska 

 (Webber).
