aline contiuuous, 5 to 7.5 x 3 to 3.5 //. Differs from D. Lirioden- 

 dri^ Cke. in its much smaller sporules. 



D. glandulosa (Cooke) Sacc? 



OvLRobuiia Pseiidacacia, March 14, \^<^\ {Nuttall, 1423, 395). 



FUSICOCCUM Corda. 



I'. ilicinum E. & E., Proc. Phila. Acad., 1894,359. 



Type habitat: On dying, transplanted, //(?.r c'/ar^!; (transplanted 

 Dec. 28, 1893), May 24, 1894 {Nuttall, discov. 1521, 496). 



Stromata cortical, convex, about i or 1.5 mm. diameter, multiloc- 

 ular, whitish inside, the tuberculiform apex pierced with a sin- 

 gle pore, rupturing the epidermis and slightly raising it. Spor- 

 ules fusoid, hyaline, nucleate 15 to 22 x 2.5 to 3 ,a. 



CYTISPORA Ehrenb. 



C. Celtidis E. & E., Proc. Phila. Acad., 1894, 360. 



Type habitat: On dead limbs Celtis occidcntalis, Feb. 2, 1894 

 {Nuttall, discov. 1358, 314). 



Stroma valsoid, flat, thin, i. 5 to 2 mm. diameter, only penetrating 

 the svirface of the bark, multilocular, gray inside, raising the bark 

 into small pustules, and finally rupturing it, cells resembling peri- 

 thecia. Sporules allantoid, 6 to 7 x i to 1.5 p.. 



C. Halesiae E. & E., Proc. Phila. iVcad., 1894, 361. 



Type habitat: On dead limbs of Mohrodetidron Carolinum {Hal- 

 esia tetrapterd), June 7, 1894 {Nuttall, discov. 1540). 



Stromata convex-conical, sunk in the bark, orbicular, about i 

 mm. diameter, white inside, unilocular, the inner surface of the cav- 

 ity lined with simple, straight basidia about 15 // long, bearing 

 the oblong-fusoid, hyaline, 2-nucleate, straight, 5 to 7 x i to 1.5 // 

 sporules, which are expelled through a single orifice perforating 

 the raised epidermis. 



This probably is the spermogonial stage of Diaporthe Halesice 

 or D. tetraptera, both of which are found in company with it. 



C. leucostoma (Pers.) Sacc. 



On cultivated Prunus domesttca di\id Atnygdalus Persica, Dec. 12, 

 1894 (Nuttall, 1769). 



C. exasperans E. & E., Proc. Phila. Acad., 1894, 360. 



Type habitat: On dead limbs Acer Peniisylvanicum, Feb. 2, 

 1894, Short Creek, alt. 1,300 ft. {Nuttall, discov. 1366). 



Stroma buried in the bark, orbicular, about i mm. diameter, 4 to 

 6-celled (at length one-celled), prolonged above into a stout, con- 

 ical beak opening by a single round pore at the apex. Sporules 

 oblong or allantoid, hyaline, 5 to 7 x 1.25 /jl. 



sp. 



On Chionanthiis Virginica, March 28, 1894 {Nuttall, 1455, 427).
