Perithecia scattered or subgregarious, on effused, blackened spots, 

 black, erumpent, convex, perforated. Asci cylindric-clavate, 8-spored, 

 Sporidia lanceolate, 5-septate, slightly constricted, dark, the two cen- 

 tral cells divided by a longitudinal septum, 32-35 x 6-8 //. 



On culms of Triticum, California. 



PL quadriseptata. Cke. & Hark. Grev. XIV, p. 10. 



Perithecia subgregarious, convex, black, shining, at first covered 

 by the epidermis, small. Asci clavate, 8-spored. Sporidia biseriate, 

 subelliptical, 4-septate, scarcely constricted, one or more of the cells 

 divided by a longitudinal septum, brown, 20-22 x 8 /i.

Pleospora sarcocystis, Sacc. Syll. 3793 and Cke. Syn. 5077. 



"Forming little, oblong, black bodies which consist of a few 

 closely joined perithecia with fleshy walls. Asci rather short, oblong, 

 but tumid, containing four oblong, obtuse, sometimes clavate sporidia 

 with three horizontal articulations, and a few vertical, 50 fi long. 

 Perhaps more properly placed in Dothidea."

PL Labiatarum, Cke. & Hark. Grev. IX, p. 8. 



Perithecia scattered, black, semiimmersed, smaller than those of

PL Sambuci, Plowr. Grev. VII, p. 74. 



Perithecia subgregarious, at first covered by the epidermis, then
