straight, bristle-lifce, abont I mm. long. Asci fusoid, 50-70x6-7/^. 

 Sporidia fasciculate, narrow cylindrical, nucleate, 16-22 x 1^-2 //, with 

 a long, slender-pointed, hair-like appendage at each end 15-20 n long. 

 On fallen and decaying leaves of Acer ruhrum, Newfield, N. J- 

 The apical appendages on the sporidia are coiled in the upper 

 part of the ascus, and when this is ruptured, protrude like the sporidia 

 in some species of Ophiobolus. The perithecia occur also on the 

 petioles of the leaf, and are more perfectly developed there, but ai-e 

 readily distinguished from those of G. emarginata by their shorter, 

 thinner ostiola and also by the color of the petiole itself, which is of a 

 lighter color when occupied by the last mentioned species. 



Specimens on Hubus Jruticosus in Kunze's Pungi Sel. 113. re- 

 ferred to G. setacea, Pers., are much like this, if not the same. 



G. Andropogonis, E. & E. in (Herb.) 



Perithecia buried in the substance of the leaf, subglobose, about 

 I mm. diam., membranaceous, black, collapsing from below. Ostiolum 

 sublateral, erumpent, cylindrical, subobtuse, projecting about J mm. 

 Asci (p. sp.) oblong-lanceolate, 40 x 10 fx, aparaphysate. Sporidia 

 fasciculately crowded, cylindric-fusoid, hyaline, septate, each cell 1-2- 

 nucleate, slightly curved, 20-25 x 4 //.

Gnomonia peiiolophzla^ Sacc. Syll, 6491, Cke. Syn. 3877, 



Perithecia minute, scattered, covered by the epidermis which it? 

 pierced by the prominently papillate or short-rostrate ostiola, depressed- 

 globose, black. Asci narrow, subcylindrical, 40-45 [i long. Sporidia 

 biseriate, nan-ow-fusiform, pointed at each end, hyaline, 12-15x2 //, 

 sometimes with 3^ nuclei.

Perithecia rather large, buried in the parenchyma of the leaf, the 

 short, rufous, subulate-conical ostiola alone being visible. Asci oblong- 

 elliptical, 40 x 7-8 /z. Sporidia fusiform, acute, pale straw-color, 

 obscurely nucleate, 11-19 x 2 /i.
