On Aristida longiramea Presl, Cuernavaca, Mexico, Sept. 27, 

 1898, E. W. D. Holway ;^020. This collection was early recog- 

 nized by Professor Holway as doubtless representing an unde- 

 scribed species. As no comprehensive survey of the American 

 grass rusts had then been made, the publication of the proposed 

 name was withheld. The gross appearance of this rust in its 

 prominent, blackish sori is not unlike that of Puccinia graminis 

 Pers. and P. Aristidae Tracy, and in the microscopic appearance 

 of both urediniospores and teliospores there is also much resem- 

 blance. The numerous capitate paraphyses, however, when 

 coupled with the other characters, easily and strongly separate 

 the species. The host is cited in Hitchcock's Mexican grasses 

 (Contr. Nat. Herb. 17: 279. 1913) from a phanerogamic speci- 

 men with same data, deposited at Washington. 



Puccinia Chaseana sp. nov. 



n. Uredinia amphigenous, numerous, scattered, oval, 0.3-0.5 

 mm. long, early naked, cinnamon-brown; paraphyses peripheral, 

 numerous, incurved, cylindric, hyphoid, 5-9 by 30-35 ju, the 

 wall uniformly thin, i ix, colorless; urediniospores globoid or 

 broadly ellipsoid, 22-28 by 24-30^11; wall cinnamon-brown, 

 moderately thin, 1.5-2 jx, closely and finely echinulate, the pores 

 4, equatorial. 



HI. Telia amphigenous, inconspicuous, few, long covered 

 by the epidermis; teliospores obovoid or obovoid-clavate, 19-26 

 by 38-45 ^, truncate or rounded above, somewhat narrowed 

 below, slightly or not constricted at septum; wall cinnamon- 

 to chestnut-brown, darker above, 1-1.5 p- thick, thicker above, 

 5-7 yu; pedicel tinted, short.

 For the material here cited we are indebted to the kindness of 

 Mrs. Agnes Chase, assistant agrostologist in the U. S. Depart- 

 ment of Agriculture, who examined the specimens of Anthephora 

 in the National Herbarium and was able to detect evidences of 

 rusts on the two collections cited. This examination was under- 

 taken at the suggestion of the senior author in order to obtain 

 material for study of Uredo Anthephorae Sydow, described in 

 1903 (Ann. Myc. i : 22) from a Cuban collection. This form was
