S. Angelicas E. & E. I. c. 



Perithecia scattered, growing under the bark and attached to it, 

 so that when the bark is peeled off, they come with it, globose, \ mm. 

 diam., collapsing below. Ostiola papilliform, barely piercing the 

 cuticle and only slightly raising it Asci clavate-cylindrical, with 

 abundant paraphyses, 65-70x7-9 /i. Sporidia biseriate, oblong- 

 elliptical, 2-nucleate, 12-15 x3| fi, becoming ovate-oblong and uni- 

 septate. 



On dead stems of Angelica atropurpurea, London, Canada. 



Judging from the specimens in F. Eur. and F. G., this is different 

 from S~ rubella, Niessl. 



S. Lactucse, E. & K. Bull. Torr. Bot. Club, XI, p. 123. 



Epiphyllous on dark brown, (3-4 mm.), concentrically wrinkled 

 spots with a distinct, raised border. Perithecia erumpent, subglobose, 

 120-150 p diam., of coarse, cellular structure. Asci oblong, sessile, 

 40-75x12-14 p. Sporidia biseriate, ovate-oblong, uniseptate and 

 constricted, 14-15 x 5 p, ends obtuse. 



On leaves of Lacluca Canadensis, Kansas (Kellerman). 



D. On monocotyledonous plants. 

 S. sabaligena, E. & E. Journ. Mycol. II, p. 101. 



Exsicc. EH. & Uvrht. N. A. F. 2d Ser. 1800. 



Perithecia gregarious, 100-125 p diam., covered by the cinereous 

 cuticle, which is scarcely ruptured over them. Asci subovate, 22-25 

 x 12-15 [i. Sporidia crowded, oblong-clavate, uniseptate, constricted 

 at the septum, subhyaline, 10-12 x3|-4 p.. 



On dead tips of leaves of Sabal Palmetto, Louisiana (Langlois). 



S. smilacina, E. & E. Journ. Mycol. II, p. 101. 



Perithecia scattered, depressed-globose, 165 p. diam., covered by 

 the cuticle, which is blackened directly over them and barely pierced 

 by the minute ostiola. Asci oblong, sessile, about 35 x 7 p. Sporidia 

 biseriate or crowded, hyaline, fusiform-oblong or clavate-oblong, uni- 

 septate, 8-11 x 2| p. The pycnidial perithecia are entirely similar to 

 the ascigerous perithecia, only a little more prominent and mostly on 

 bleached stems, and contain stylospores oblong or elliptical-oblong, 

 hyaline, 2-nucleate, uniseptate and slightly constricted, 7-8 x 3 3J p. 

 (Diplodina Smilacis, E. & E.)
