0. consimilis, E. & E. (in Herb.) 



Perithecia scattered, subcuticular, finally exposed by the falling 

 away of the cuticle, ovate-globose, small, about 200 fi diam., with a 

 short-cylindrical, projecting ostiolum. Asci cylindrical, stipitate, 75- 

 100 X 8 n, with paraphyses crisped and more or less matted together 

 above. Sporidia filiform, multiseptate, yellow, nearly as long as the 

 asci, without any swollen joint, about 2 fi thick. 



On old tomato stems, Newfield, N. J., and on okra stems, Louisi- 

 ana. 



In the Louisiana specc. the perithecia are often on red stains, just 

 as in 0. porphyrogonus, but this is easily distinguished from that 

 species by its smaller perithecia, shorter and broader asci and sporidia. 



0. fllisporns, (C. & E.) 



^phizriafiUspora^ C. & E. .Grev. VII, p. lo. 

 Ophiobolus Jilisporus, Sacc. Syll. 4074. 

 Raphidospora fiUspora, Cke. Syn. 4581. 



Perithecia lenticular, \ mm. diam., scattered, covered by the epi- 

 dermis which is slightly raised and perforated, and stained olive-black. 

 Asci linear, 112-150 x 5-6 jx. Sporidia filiform, nearly as long as the 

 asci. 



On dead stems of Smilax, Newfield, N. J. Apparently rare. 

 Closely allied to O. stictisporus, (0. & E.) 



0. trichisporns, E. & E. (in Herb.) 



Perithecia scattered, erumpent-superficial, ovate-conical, about 

 400 // high and 300 /j. broad, narrowed gradually above into a stout, 

 obtuse, cylindric-conical apex, glabrous, black, membranaceous. Asci 

 linear, paraphysate, 180-220 x3-3| /x. Sporidia about as long as the 

 asci, very slender filiform or capillary, nucleate, scarcely | pi thick, 

 yellowish-hyaline. 



On dead culms of some grass, London, Canada (Dearness). 



The asci and sporidia scarcely differ from those of O. stictisporus, 

 (C. & E.), but the erumpent-superficial perithecia easily separate this 

 from that species. 



0. implexns, (E. & E.) 



Lophiostoma (^Lophionema) implexum^ E. & E. Journ. Mycol. IV, p. 75. 



Perithecia gregarious, brown strigose, ovate, about \ mm. diam., 

 subcnticular, the obtuse-conical, slightly compressed ostiolum and upper 

 part of the perithecia erumpent. Asci 150-160x8-10 //, clavate^ 

 cylindrical, with abundant filiform paraphyses. Sporidia filiform.
