334 PROCEEDINGS OF THE ACADEMY OF [1895. 



subelongated areas of the stalk, suberumpent. pierced above, 10(i— 

 150// diam. Sporules oblong-cylindrical, hyaline, yellowish in the 

 mass, uniseptate, not constricted, obtuse, 6— 8 x 1J— 2 /v.. 



Very different from A. zeina Sacc. which is on the leaves and has 

 sporules 18x7 //. 

 Diplodina Coloradensis E. & E. 



On dead stems of Gutierrezia Euthamiae, Fort Collins, Colo, 

 March, 1895. C. F. Baker, No. 333. 



Perithecia subgregarious, often subseriate, erumpent-superficial, 

 small, about 200//., black and shining, subglbose, with a papilliform 

 ostiolum. Sporules oblong, obtuse, uniseptate, but mostly not con- 

 stricted, smoky-hyaline, 6-8 x 2?-3 ,«. 



Near D. Galii Niessl, but apparently distinct; that species having 

 ovate, constricted sporules. 

 Septoria variegata E. & E. 



On leaves of Rhamnus Purshiana, Shasta Springs, Siskyou Co., 

 Cala., Aug., 1894. W. C. Blasdale. 



Spots numerous, dark rusty-brown, becoming light rusty-brown, 

 2-8 mm. diam., with a small, white spot in the center, or in the 

 larger spots, with numerous white spots arranged so as to present a 

 zonate or marbled appearance, as in Septoria musiva Pk. Peri- 

 thecia epiphyllous, but often visible below, seated on the small white 

 spots, broadly open above, 100-110 /». diam. Sporules clavate-cyl- 

 indrical, irregularly curved, hyaline, nucleate, becoming 3-septate, 

 25-55 x 3-43 :>.. 



Seems to be quite distinct from all the other species on Rhamnus. 

 On account of the imperfectly developed perithecia, this approaches 

 Cy lindrosporium . 

 Septoria Asplenii E. & E. 



On leaves- of Asplenium angustifolium, Mich. Ag. College, 1891. 

 G. H. Hicks. Comm., Mr. L. N. Johnson. 



Spots dull dirty-white, with a broad reddish-brown border, 3-4 

 mm. wide, including border. Perithecia sparingly scattered on 

 the spots, small, 65-75 //, pale-brown, perforated above, only 

 slightly prominent. Sporules filiform, continuous, "several-sep- 

 tate" (sec. Mr. Hicks), curved, subequal, hyaline or greenish-hya- 

 line, 35-45 x 1] ,". 

 Septoria ourvispora E. & E., N.A.F., 3,270. 



On leaves of Acer glabrum, Shasta Springs, Cala., Aug., 1894
