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

 ^5-28 n long, generally slightly curved. 



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



The perithecia are so small as to be easily o^-erlooked. The spo- 

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

 •distinctly septate. 



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



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

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

 ridia oblong, 1 2-15 x 3|— 4 p.. 



On scales of dead spikes of Lycopodivm davatum, Adirondack 

 Mts., New York. 



This differs from S. lycopodina hv 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 PJioma with oblong 5-7 x 2-2i jjt sporules. Sec. Fckl. the 

 Phonia accompanying Sphmrella 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 lophospora, Sacc. 



In the following Schweinitzian species, apparently referable to 

 the Sphcerelloidem, 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 suhhullans, Schw. Syn. N. Am. 1797. — Spots buUate- 

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

 perithecia, with only their papillate ostiola visible. 



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



Sphoeria 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. 



SpJuxria 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.
