JAN. 1896. FLORA OF W. VIRGINIA MILLSPAUGH & NUTTALL. in 



aline continuous, 5 to 7.5 x 3 to 3.5 p.. Differs from D. Lirioden- 

 dri, Cke. in its much smaller sporules. 



D. glandulosa (Cooke) Sacc? 



QaRobmia Pseudacacia, March 14, \^\ (Nuttall, 1423, 395). 



FUSICOCCUM Corda. 



F.ilicinum E. & E., Proc. Phila. Acad., 1894,359. 



TYPE HABITAT: Ondying, transplanted, Ilex opaca (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 /*. 



CYTISPORA Ehrenb. 



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



TYPE HABITAT: On dead limbs Celtis occidentalis, Feb. 2, 1894 

 (Nuttall, discov. 1358, 314). 



Stroma valsoid, flat, thin, 1.5 to 2 mm. diameter, only penetrating 

 the surface 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 ;j.. 



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



TYPE HABITAT: On dead limbs of Mohrodendron Carolinum (Hal- 

 esia tetraptera), 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 Halesia 

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



C. leucostoma (Pers.) Sacc. 



On cultivated Prunus domestica and Amygdalus Persica, Dec. 12, 

 1894 (Nuttall, 1769). 



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



TYPE HABITAT: On dead limbs Acer Pennsylvanictim, 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 //. 



C. - sp. 



On Chionanthus Virginica, March 28, 1894 (Nuttall, 1455, 427).
