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

 sporidia 20-23 X 3-31 /i. 



On dead stems of Ba'ptisia tictoria, with Sphcerella haptisiicola, 

 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 haptisiicola, Cke., in which the perithecia are more scat- 

 tered and the sporidia shorter (12-16 fi ), and broader (4r-5 /z). The 

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

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

 described h\ Cooke.

Perithecia amphigenous, globose, 75-80 ^u (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, 35^0 x 12-15 a (34^36 x 8-10 /z, Winter). Sporidia bise- 

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



X 3-3J //, hyaline. 



On leaves of Oxalis corniculata, var. stricta, 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 [i diam., of coarse cellulai- structure, 

 A^ith 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 [i. Sporidia crowded, ovate-oblong, granu- 

 lar and nucleate, (becoming uniseptate?) 12-16x3-4^ fi. 



On leaves of Thalictrum dioicum, 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. brqjid, globose, very small, (60-70 )ju, 



perforated above, black. Asci fasciculate, slightly attenuated upwards 



' from the subventricose base, very shoi't-stipitate, 8-spored, 26-3;0 x 7 //.
