the culm, attached above to the inner surface of the cuticle and cov- 

 ered with loose, spreading, weak, brawn, septate hairs 200-300 p long 

 by about 3 p thick. On culms of Spartina, lying partly buried in the 

 sand on the beach at Cape May, N. J., and on culms and sheaths of 

 Andropogon muricatus, Louisiana (Langlois).

Perithecia gregarious, soon exposed, ovate, black, smooth, hard, 

 shining, papillate, | mm. diam. Asci cylindrical, 80-110 x 10-12 p. 

 Sporidia filiform, multiseptate, yellowish, 80-100 x 2|-3 p (120 p long 

 Cke.). 



On dead stems of Bidens, Newfield, N. J., and on dead stems of 

 Aster, Texas (Ravenel). 



The sporidia, when mature, are slightly enlarged at the upper end, 

 which is a little curved to one side and bear's a striking resemblance 

 to the head of a serpent. The paraphyses are abundant and a little 

 longer than the asci. 



0. hamasporus, E. & E. Journ. Mycol. III, p. 117. 



Perithecia scattered, globose, membranaceo-carbonaceous, \-\ mm. 

 diam., black, buried in the substance of the leaf, except the erumpent, 

 convex-flattened apex. Asci 70 x 8-10 p, narrowed above, but obtuse. 

 Paraphyses (?). Sporidia 8 in an ascus, filiform, multinucleate, yellow- 

 ish-hyaline, 30-35 xl| p, narrowed to a point below, and about one 

 third of the lower part bent almost to a right angle, or even curved 

 into a hook (i. e., after the sporidia have escaped from the asci). The 

 general aspect is that of Didymosphceria cupula, Ell., only the peri- 

 thecia are not collapsed. The ostiolum is indistinctly papilliform. 



On fallen leaves of Quercus tinctoria (?), Manhattan, Ks., July, 

 1887 (W. T. Swingle). 



The leaf is sometimes blackened around the perithecia, indicating 

 the presence of an imperfect stroma.

This (sec. specc. in our Herb. det. by Cooke) belongs to the
