24 Thirty-third Annual Report of the 



form ; spores oblong, obtuse, colored, three to five-septate, sometimes 

 with one or two longitudinal septa, .0008 in. to .001 in. long. 



Dead twigs of Colutea arbor escens. Buffalo. Clinton. 



Sphaeropsis brunneola, P. & O. Dead stems of Smilax Mspida. 

 Buffalo. Clinton. The specimens do not fully accord with the descrip- 

 tion of the species, but probably belong to it. 



Sphaeropsis phomatella, n.sp. Peri thecia numerous, minute, seated 

 on indefinite whitish or pallid spots, covered by the epidermis which 

 is at length ruptured, black ; spores oblong, at first hyaline, then 

 colored, .0008 in. to .0012 in. long ; sporophores short. 



Dead shoots of ash, Fraxinus Americana. West Troy. May. The 

 perithecia are very small and at first sight suggest the idea of a Phoma. 



Sphaeropsis abundans, n. sp. Perithecia numerous, erumpent, closely 

 surrounded by the ruptured epidermis, black ; spores very unequal, 

 elliptical or oblong, at first hyaline and pedicellate, then colored, ob- 

 tuse, .00065 in. to .0009 in. long, about .0005 in. broad. Dead twigs 

 and branches of rock chestnut oak. Albany and North G-reenbush. 

 May. The twigs are roughened by the numerous perithecia and they 

 sometimes have a darker appearance where they are affected by the 

 Sphaeropsis. The epidermis is ruptured very irregularly. Sphceropsis 

 dryina differs in its smaller colorless spores, and S$. li?iearis,[m its linear 

 arrangement. This last species occurs also on young dead shoots of 

 hickory, Carya alia. 



Sphaeropsis cerasina, n. sp. Perithecia numerous, small, seated on 

 the inner bark, covered by the slightly elevated epidermis which is at 

 length pierced or slightly ruptured, black, often cinereous above; spores 

 at first hyaline, then colored, ellipticalobovate or oblong, .0008 in. to 

 .001 in. long; sporophores short. Dead branches of choke cherry, 

 Prunus Virginiana. West Albany. May. 



Sphaeropsis seriatus, n. sp. Perithecia hard, crowded or subcaespitose, 

 arranged in long lines in the chinks of the rough bark, black ; spores 

 at first pale, then colored, ellipticalo bovate or oblong, .0008 in. to .001 

 in. long. Dead bark of sassafras, Sassafras officinale. Center. May. 

 The hard sclerotoid perithecia and the linear arrangement of the 

 clusters make this a very distinct species. 



Sphaeropsis celastrina, n. sp. Perithecia numerous, small, seated on 

 the inner bark, covered by the epidermis which is slightly elevated and 

 at length pierced or slightly ruptured ; spores oblong or oblong-ovate, 

 colored, .0008 in. to .001 in. long. Dead stems of bitter-sweet, Celastrus 

 scandens. Charlton. July. This is quite unlike S. propullansm which 

 the perithecia are much larger and caespitose. The epidermis is usually 

 whitish or cinereous over each perithecium and it ruptures slightly, 

 forming a small aperture. 



Sphaeropsis imilacina, n. sp. Spots orbicular, 2 lines to 3 lines broad, 

 arid, whitish with a dark border; perithecia epiphyllous, subhemis- 

 pherical or depressed, black, often disposed in a circle near the margin 

 of the spot ; spores oblong or subfusiform, colorless, .0008 in. to .0012 

 in. long, about .0003 in. broad. Living leaves of green brier. Smilax 

 rotundifolia. Wading River. Sept. 



Septoria pastinacina, n. sp. Spots extended, indefinite, brown ; 

 perithecia minute, .005 in. to .006 in. broad, numerous, surrounding 

 the stem on all sides, covered by the epidermis which is pierced by the
