ridia crowded, elongated, hyaline, simple or obscurely uniseptate, 

 :25-28 fi long, generally slightly curved. 



On dead leaves of Pteris aquilina, New York State (Peck). 



The perithelia are so small as to be easily overlooked. The spo- 

 ridia are unlike those of S. Pteridis, being twice as long and not 

 distinctly septate. 



S. Lycopodii, Pk. 39th Rep. p. 51. 



Perithecia minute (100 //)., blackish. Asci oblong or subcylin- 

 drical, often slightly narrowed toward the apex, 30-40 x 10 /i. Spo- 

 ridia oblong, 12-15 x 3|-4 p.. 



On scales of dead spikes of Lycopodium clavatvm, Adirondack 

 Mts., New York. 



This differs from S. lycopodinu in its place of growth and in its 

 smaller asci and sporidia. 



S. superflua, Fckl. in Ell. & Evrht.'s N. A. F. 2d Ser. 2134. 



A reexamination of the specc. in the copies now accessible shows 

 only a Phoma with oblong 5-7 x 2-2 \ p sporules. Sec. Fckl. the 

 Phoma accompanying Sphcerella superflua has sporules "cylindrical, 

 curved, minute," indicating a different thing from this. 



S. pandurata, E. & E. Bull. Torr. Bot. Club, X, p. 117, is Didy- 

 mella lophospo?*a, Sacc. 



In the following Schweinitzian species, apparently referable to 

 the Splicer elloid em, the fructification is unknown. 



Sphceria tigrinans, Schw. Syn. N. Am. 1804. Spots round or 

 subirregular, about 4 mm. diam., darker in the center, on account of 

 the abundant, minute, astomous, black perithecia. 



On the under side of oak leaves. Allied to S. myriadea. 



Sphmria subbullans, Schw. Syn. N. Am. 1797. Spots bullate- 

 elevated, orbicular, black, covered with the numerous, innate, minute 

 perithecia, with only their papillate ostiola visible. 



On the upper side of leaves of Pyrus Malus, Bethlehem, Pa. 



Sphceria Staphylew, Schw. Syn. N. Am. 1800. Perithecia scat- 

 tered or aggregated, innate, minute, irregular, flattened, black, asto- 

 mous, furnished with a distinct, included sack, finally empty. 



Very common on capsules of Staphylea trifolia, Bethlehem, Pa. 



Sphwria plantaginicola, Schw. Syn. N. Am. 1806. Perithecia 

 minute, punctiform, very black, innate on both sides of the leaf, sub- 

 -conically elevated, astomous, thickly but irregularly scattered, shining, 

 becoming empty, but hard, so as to be with difficulty cut.
