Often in >some of the asci the sporidia appear shriveled and are 

 nearly opake. 

 Lophidium confertum E. & E. 



On decorticated, decaying limbs of Fraxinus viridis, Trego Co., 

 Kansas, Apr. 1894 (Bartholomew, No. 1,457). 



Perithecia crowded, superficial, with the base broadly adnate, 

 conical, somewhat shining above, 300-400// diam. Ostiolum ob- 

 tusely conical, mostly more or less compressed, with the opening 

 elongated subhysteriform. Asci clavate-cylindrical, 100-110x12- 

 15.", with a short, crooked stipe and abundant paraphyses. Sporidia 

 uniseriate, short-elliptical, pale yellow-brown, 3-septate, obtuse, more 

 or less constricted at the middle septum, coarsely niuriform, 12-15 

 X 10-12//. Sometimes the sporidia are smaller and darker with a 

 shriveled look. On account of the slightly compressed ostiola this 

 approaches TeicJtospora. 

 Cucurbitaria borealis E. & E. 



On bark of dead limbs of Salix sp., Alcove, N. York (C. L. 

 Shear, No. 216). 



Perithecia cespitose, 6-12 together in compact groups, 2-3 mm. 

 diam., seated on the surface of the inner bark and loosely surrounded 

 by the ruptured and upturned epidermis, 3-2 mm. diam. , black, 

 rough, subglobose, with a prominent ostiolum soon perforated. . Asci 

 cylindrical, short-stipitate, paraphysate, 8-spored, 90-110 x 15—16//. 

 Sporidia uniseriate or subbiseriate above, elongated ovate- elliptical, 

 about 7-septate and niuriform, somewhat constricted in the middle, 

 yellow-brown, obtuse, 20-27 x 12-14//. 



Differs from C. salicina Fckl. in its cespitose perithecia and larger, 

 7-septate sporidia. 



Sphaerella hypsicola E. & E. 



Perithecia scattered or subgregarious, ovate- globose, 80-90/'. diam., 

 subcuticular or superficial by the falling away of the epidermis, 

 pierced above with a small round opening. Asci oblong, sessile, 

 fasciculate, 25-35 x 7-8/', 8-spored. Sporidia crowded-biseriate, 

 oblong or clavate-oblong, scarcely constricted, hyaline, 9-11 x2i- 

 3/'.

 July, 1894, alt. 10,200 ft. (Prof. C. S. Crandall, No. 4).
