CONTRIBUTIONS TO WESTERN BOTANY. 727 



Utah and Nevada since 1880, has never seemed to me 

 anything more than the normal form of the species, while 

 the form on which the type Nevadensis was based is the 

 less frequent one found in the valleys in less gravelly or 

 clay soil. The variety abounds on sandy or gravelly 

 hills, especially in rocky places and among rocks; it is 

 even found on cliffs. It abounds throughout Utah as far 

 north as the lower end of Salt Lake Valley and westward, 

 and as far eastward as western Colorado.

On Vicia Americana. 



Spores somewhat smaller than as described, but not 

 otherwise different. 



Pleospora Utahensis E. & E. 



No. 5902. August 24, Falls of Bullion Creek, Utah, 

 9500° alt. 



On dead stems of Eii^atorium occidentale. Perithecia 

 scattered, erumpent-superficial, depressed-globose, spar- 

 ingly fringed around the base with short, coarse, brown 

 hyph«, finally collapsing above, 150-250 m. diam., with 

 a papilliform ostiolum. Asci oblong, rounded above, 

 75-90x20-23 m., paraphysate, 8-spored, with only a short 

 rudimentary stipe. Sporidia crowded, biseriate, oblong- 

 elliptical, at first yellow, uniseptate and constricted, then 

 3-septate, and finally about 7-septate, muriform and dark 

 brown, 20-23x14-16 m. 



This differs from P. Richtofhensis E. & E. in its smaller, 

 more distinctly rumpent perithecia and comparatively 

 broader sporidia, and from P. alpestris E. & E. in its 

 8-spored asci and smaller sporidia.
