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

 sporidia 20-23 x 3-3 \ u. 



On dead stems of Baptisia tictoria, with Sphceretta 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 // ), and broader (4-5 //). The 

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

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

 described bv Cooke.

Perithecia amphigenous, globose, 75-80 p. (40-46 //, Winter A: 

 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, 

 s-^pored, 35-40 x 12-15 (34-36 x 8-10 //, Winter). Sporidia bise- 

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



x 3-3J //, Iwaline.

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

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

 onymv is from Winter's Pilze.

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 /JL. Sporidia crowded, ovate-oblong, granu- 

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

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

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

 perforated above, black. Asci fasciculate, slightly attenuated upwards 

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