fusiform, slightly curved, hyaline, granular at first, then uniseptate 

 sporidia 20-23x3-3 J p. 



On dead stems of Baptida tictoria, with Sphcerella baptisiicola, 

 Cke., Newfield, N. J. 



The specimens found grew around the base of the stem, extend- 

 ing up for about two inches, where they were abruptly succeeded by 

 Sphcerella baptisiicola, Cke., in which the perithecia are more scat- 

 tered and the sporidia shorter (12-16 p ), and broader (4-5 p). The 

 specimens of this latter species, in Rav. F. Am., are not well devel- 

 oped and have the sporidia narrower (3-3| p), and more acute, as 

 described by Cooke.

Perithecia amphigenous, globose, 75-80 p (40-46 p, Winter & 

 Sacc.), broadly perforated at the apex, base sunk in the substance of 

 the leaf, generally seated in the center of round whitish spots 1-3 

 mm. diam., with a brown border. Asci ovate-oblong, nearly sessile, 

 8-spored, 35-40 x 12-15 a (34-36 x 8-10 p, Winter). Sporidia bise- 

 riate, oblong, obtuse, septate in the middle but not constricted, 10-14 



x 3-3J p, hyaline. 



On leaves of Oxalis corniculata, var. stricfa, Columbia, So. Car- 

 olina (Atkinson). 



The Carolina specc. agree in all respects, size of perithecia, asci 

 and sporidia, with the specc. in Kriegers Fungi Saxonici. The syn- 

 onymy is from Winter's Pilze. 



S. Thalictri, E. & E. Journ. Mycol. I. p. 44. 



Perithecia hypophyllous, 90 p diam., of coarse cellular structure, 

 with a rather large opening above, hemispherical (flattened when dry), 

 scattered on small (2-3 mm.), round, white spots with a dark border. 

 Asci sessile, about 36 x 7 p. Sporidia crowded, ovate-oblong, granu- 

 lar and nucleate, (becoming uniseptate?) 12-16x3-4| p. 



On leaves of Thalictrum dioicu?n, New Jersey and Iowa. 



S. Earliana, Winter. Journ. Mycol. I, p. 101. 



Perithecia amphigenous, densely crowded in small, black, angular, 

 roundish patches about 1-2 mm. broad, globose, very small, (60-70 )p, 

 perforated above, black. Asci fasciculate, slightly attenuated upwards 

 from the subventricose base, very short-stipitate, 8-spored, 26-30 x 7 p.
