Dothichloe Hypoxylon Atk. Bull. Torr. Club, 21 : 223. My. 

 1894. 



I refer here as being typical of this much named species, 

 Rolf's no. 22, on an unknown grass from Lake City, Florida, 

 Oct., 1896. 



The stroma is crust like, often 2.3 cm. long and is slightly 



roughened throughout by the small, numerous, slightly papillate 

 osteola. 



A word is perhaps necessary in regard to the selection of the 

 above name for this species. Hypocrea atramentosa B. & C. 

 seems to have been founded on material from both Cuba and 

 Alabama. There can be little question but that the Alabama 

 material at least represented the same species that was later 

 . described as Epichloe Hypoxylon Peck and Dothidea vorax B. & C. 

 If it should prove that the Cuban material differs from Peck's a 

 specific name would have to be adopted for the form found in the 

 United States. Atkinson's proposed genus Dothichloe has not been 

 recognized by either Saccardo (Hedwigia, 35 : 34), nor by Lindau 

 (Engler & Prantl. Nat. Pflanzfam.). The characters by which 

 he seeks to separate it from Ophiodothis seem rather slight and 

 even if, as he suggests, the character of the stroma of such species 

 as 0. Haydeni (B. & C.) Sacc. are sufficiently different to consti- 

 tute a good generic distinction, the name Ophiodothis would, ac- 

 cording to the method of generic types, now happily being some- 

 what widely recognized, have to remain with the present species, 

 as it is the first one mentioned under this generic name. Dothidea 

 atramentaria B. & C. and D. pilulaeformis B. & C. are recognized 

 as varieties of this species by Saccardo. In the case of the 

 former (see Rav. Fung. Amer. no. 100) there seems to be noth- 

 ing on which to base a varietal distinction and it \A therefore here 

 included as a synonym. The latter (see Tracy's no. 167 on
