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

 25-28 fj. long, generally slightly curved. 



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



The perithecia 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 fj.. Spo- 

 ridia oblonsr, 12-15x3i-4 .

On scales of dead spikes of Lycopodium clave/turn, Adirondack 

 Mts., New York. 



This differs from S. lycopodina 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 reexaminatioii of the specc. in the copies now accessible shows 

 only a Plioma with oblong 5-7 x 2-2 J JJL sporules. Sec, Fckl. the 

 Phoma accompanying Sphcerella superflua has sporules "cylindrical, 

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



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

 mcUa lophospora^ Sacc. 



In the following Schweinitzian species, apparently referable to 

 the Sphcerettoidece, the fructification is unknown. 



Sphceria tiyt'hn.ins, Schw. Syn. N. Am. 1804. Spots round or 

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

 the abundant, minute, astomous, black perithecia. 



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



Sphceria subbuUans, 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 Staphylece, 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. 



Sphceria 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.
