6-8eptate and constricted at the septa, generally with one cell near 

 the middle, swollen, 22-27 x 6-7/^1, golden-yellow. 



Differs from L. agnita Desm. in its broader, golden-yellow 

 Bporidia. L. Samhaci in Roum. F. Gall. 5960, has 3-septate sporidia. 



Leptosphaeria papyricola E. & E. 



On old pasteboard lying by the roadside, Newfield, N. J,, Aug. 

 1894. 



Perithecia gregarious, buried, with the acutely conical ostiolum 

 erurapent, llO-loO," diam. , ovate-globose. Asci (p. sp.) 60-70 x 

 5a, with a siender stipe 30-40// long, paraphyses obscure. Sporidia 

 biseriate, fusoid, dull yellow, slightly curved, 3-septate, often con- 

 stricted at the middle septum with the next cell above swollen, 14- 

 20 (mostly about 15) x 21-3//. 



Differs from au}'^ form of L. eustoma (Fr. ) in its conical ostiolum 

 and constantly narrower sporidia. 



An Ophiobolus with asci 110-120 x 5//, spoi'idia filiform 80-110 

 X lo,", also occurs on the same matrix. 



Ophiobolus fragilisporus E. & E. 



Perithecia scattered, erumpent-superficial, ovate-conical, brownish- 

 black, 350-450// high, 300-350// thick, ^ narrowed above into the 

 prominent- papilliform or short- cylindricaj, black ostiolum. Asci 

 linear, gradually narrowed below, 150-200 x 5-5*//. Paraphyses 

 filiform, evanescent. Sporidia nearly as long as the asci, yellowish- 

 brown, 1-1]// thick, readily separating into joints 8-12// long. 



Allied to 0. rudis (Riess.), but sporidia only half as thick and 

 perithecia ovate-conical. 



On dead herbaceous stems, on overflowed land, Walton Creek, 

 Colorado, July, 1894, alt. 6,500 ft. (Prof C. S. Crandall, No. 40). 



Linospora Brunellae E. & E. 



On living leaves of Brunella vulgaris, Columbia River, W. 

 Klikitat Co., Wash., Apr. 1886 (W. N. Suksdorf, No. 267). 



Perithecia thickly scattered, amphigenous, l^uried in the substance 

 of the leaf, but raising the epidermis into little black tubercles about 

 i mm. diam. , and pierced above by the papilliform or short-cylindri- 

 cal ostiolum. Asci clavate-cylindrical, 80-90x12-15//, 8-spored, 

 (paraphysate)? Sporidia fasciculate, lying parallel, clavate-cylindri- 

 cal, yellowish-hyaline, 3-septate, not constricted, 55-65 x 3//.
