b<ut the arrangement of the perithecia is different and sporules 



septate. 



Diplodia Umbellulariae E. & E. 



On dead twigs and limbs of Umbellularia Californica, Pasadena, 

 Gala., Aug., 1894. Prof. A. J. McClatchie. 



Perithecia scattered singly or oftener in short series of 3-6, bedded 

 in the blackened, almost stromatic, substance of the inner bark and 

 raising and splitting the epidermis into short, longitudinal cracks, 

 through which their minute, papilliform ostiola are barely visible, 

 150-200 ,'/. diam., whitish inside. Sporules elliptical, broadly con- 

 stricted at the septum, dark-brown obtuse, 16-20 x 8-10, a, on pedi- 

 cels about as long as the sporules. 



Similar but smaller perithecia on the same limbs produce, oblong- 

 elliptical, pale-brown, 8-1 Ox 4-5 // sporules Coniothecium Umbellu- 

 lariae E. & E. . Other perithecia contain oblong, 5-septate sporules 

 25-30x7-9//-, on hyaline pedicels 8-12 /j. long terminal; cells of 

 sporules hyaline, intermediate ones olive-brown. Hendersonia Um- 

 bellulariae E. & E. 



Diplodia officinalis E. & E. 



On dead limbs of Sassafras officinalis, New Brunswick, N. J. 

 Prof. B. D. Halsted. Michigan, G. H. Hicks. 



Perithecia evenly but thickly scattered, subepidermal, depressed- 

 globose, 150-200// diam., covered by the blackened epidermis 

 which is raised into distinct pustules pierced at the apex by the 

 papilliform ostiola. Sporules oblong, dark-brown, septate in the 

 middle, but not constricted, 15-22 x 7-8 //.. 



Differs from D. Sassafras Tr. & E. in its larger sporules septate 

 in the middle, and in growing on dead, instead of living limbs. 



Botryodiplodia ostiolata E. & E. 



On bark of dead Quercus alba. Ohio. Morgan No. 1,051. 



Perithecia fasciculate, 12-20 together, conic-cylindrical, 1-1 £ 

 mm. long, white inside, joined at base in a black, subcuticular 

 stroma, erumpent through the thick epidermis, and when growing 

 on the side of a log or limb, curving upward. Sporules elliptical, 

 20-25 x 11-12 ix, uniseptate, brown. 



Ascochyta zeicola E. & E. 



On old stalks of Zea Mays, Newfield, N. J., May, 1895. 

 Perithecia gregarious, on slightly darker, irregular shaped or
