apex, 110x45 //, with a very short pedicel, 8-spored. Sporidia 2-3- 

 seriate, elongated-fusoid, uniseptate, 4-guttulate, 45-50 x 10-13 p, with 

 a hyaline, gelatinous envelope.

Astragalus adsurgens and A. hypoglottis, Montana (Anderson). 



Page 317. After Didymella Raiiii, insert 



D. Smilacis, E. & E. (in Herb.) 



Perithecia gregarious, globose, about J mm. diam., closely cov- 

 ered by the cuticle which is blackened over them and raised into little 

 pustules barely pierced by the papilliform ostiolum. Asci clavate- 

 cylindrical, 35-40 x 5-6 /i, paraphysate. Sporidia biseriate above, 

 uniseriate below, ovate-oblong, hyaline, uniseptate and slightly con- 

 stricted at the septum, 8-10 x3 jut. 



On dead stems of Smilax, Newfield, N. J. 



Differs from Didymosphmria polysticta, (B. & C), in its hyaline 

 sporidia, and from Physalospora disrupta, (B. & C), in its uniseptate 

 sporidia and different asci. The habit is exactly that of Anthosto- 

 mella sepelibilis, (B. & C). Sphcerella smilacina, E. & E., grows on 

 stems not as much decayed, and has smaller perithecia and asci with- 

 out paraphyses.

 lowing new species 



D. Manitobiensis, E. & E. (in Herb.) 



Spots orbicular, brown, 2-3 mm. diam., surrounded by a light- 

 colored border, fainter and purplish. below. Perithecia clustered in 

 the center of the spots, mostly 3-8 together, erumpent-superficial, sub- 

 hemispherical, black, rough, 150-200 p. diam., the apex and papilliform 

 ostiolum smoother and shining. Asci clavate-cylindrical, subsessile, 

 8-spored, paraphysate, 65-75 x 8-10 p. Sporidia subbiseriate, obovate- 

 oblong, uniseptate, the septum nearer the narrower end, 12-15 x 4-5 /i, 

 brown.

 river, Manitoba, Oct. 3, 1891 (Dearness).

Perithecia gregarious, depressed-globose or subhemispherical.
