152 PROCEEDINGS OF THE ACADEMY OF [1893- 



Ascomata gregarious, erumpent, orbicular, 1 mm. or a little less 

 in diam., depressed-hemispheric at first, then open, discoid and 

 applanate, brown-black outside, margin incurved and finely fimbri- 

 ate-toothed. Disk slightly concave, (when dry) cinereous. Asci 

 sessile, oblong-cylindrical, 75-80 x 8/-*. Paraphyses about equaling 

 the asci, tips brown and bearing small brown, globose 3/x diam., 

 conidia. Sporidia vermiform-fusoid, curved when free so as to form 

 a semicircle or even an imperfect spiral, 35-50// long, about 3 or 

 3?/>. thick in the middle tapering gradually to each end, nucleate, 

 becoming 7-10-pseudo-septate, hyaline. 



* * * UREDINEJE AND USTILAGINEJE. 

 Puccinia distichlydis E. & E. 



On Distichlys maritime/,, Helena, Montana. Sept., 1891. (Rev. 

 F. D. Kelsey, No. 23.) 



III. Sori elongated 2-10 mm. long and 1-2 mm. wide, erumpent, 

 naked, nearly black. Teleutospores oblong or oblong-elliptical, 

 45-70 x 15-20//, constricted in the middle, pale-brown, becoming 

 deep chestnut brown ; epispore smooth, thickened at summit which 

 is either regularly rounded or subacuminately or mucronately 

 pointed. Pedicels, 80-100/.* long, stout (6-7/* thick) and persis- 

 tent, yellowish-hyaline. 



Seems distinct from P. graminis, in its longer, more distinctly con- 

 stricted spores on longer, stouter pedicels. 



Puccinia douglasii E. & E. 



On leaves of Phlox douglasii, Detroit, Utah. May, 1891. (M. 

 E. Jones, No. 25.) 



III. Sori amphigenous, minute, J-$ mm., naked but closely 

 embraced by the epidermis, rather pale chestnut color or sometimes 

 darker, mostly seriate, a single series of sori being arranged along 

 each side of the midrib, the leaf being slightly thickened. Teleuto- 

 spores oblong-elliptical, 25-55 x 12-15//, chestnut brown, constricted, 

 rounded at the apex or obtusely pointed, epispore smooth, distinctly 

 thickened at the apex, with or without a papilla. 



Differs from P. plumbaria Pk., in its smaller, naked sori, which 

 are also much smaller than in P. giliae Hark. 



Puccinia gutierreziae E. & E. (P. Bigelovia, E. & E., N. A. F. 2,248.) 



On leaves of Gutierrezia euthamia, Digway, Utah. June, 1892. 

 (M. E. Jones, No. 23.)
