Spheeria subsolitaria Schw. in Herb. Schw. 



Sphceropsis Sumachi C. & E., Grev., V, p. 31, pi. 75, fig. 11. 



These are all pycnidia of Sphceria ambigxa Schw., Syn. N. Am., 

 1,492 = Botryosphosria fuliginosa (M. & N. ). See N. A. Pyr., p. 546. 



Sphaeropsis Ruboruni (Schw.). 



Sphceria Ruboruni Scliw., Syn. X. Am., 1,677. 

 Sphceropsis rubicola C. & E., Grev., VI, p. 2, pi. 95, fig. 2.. 



The spec, in Herb. Schw. affords no spores ; but Starbiick (1. c.) 

 finds specc. of Sphceria Ruborum Schw. in Herb. Fr. , which are 

 identical with specc. of Sphceropsis rubicola C. & E. 



Sphaeropsis pericarpii (Schw.). 



Sphceria pericarpii Schw., Syn. N. Am., 1,590. 

 Sphceropsis pericarpii Pk. 25th Rep., p. 85.

 Sphceria involucri Schw. in Herb. Schw.? 



On pericarp of hickory nuts, Bethlehem, Pa. (Schw.), N. York 

 State (Peck), New Jersey (Ellis). 



In the Schweinitziau spec, of S. involucri, some of the sporules 

 are uuiseptate, but the greater uumber are without septa. The 

 sporules in all the above quoted specc. are about 20-25 x 10—12//. 



Discosia placentula (Schw.). 



Sphceria placentula Schw. in Herb. 



Discoid, orbicular, about \ mm. diam. , black, somewhat wrinkled, 

 umbilicate- depressed in the center, the papilliform ostiolum seated 

 in the center of the depression. Sporules oblong-cylindrical, slightly 

 curved, hyaline, faintly 4-nucleate, 10-13 x \\—%x, with an oblique, 

 hyaline, slender bristle at each end about as long as the spore itself. 



On some decaying leaf (Tilia)?, Bethlehem, Pa, (Schweinitz.). 



Sphceria fibriseda Schw., Syn. N. Am., 1,542. 



Perithecia globose or oftener suboblong, 55-75//. diam., very 

 abundant but entirely sterile — no asci or sporidia. Apparently an 

 abortive Nectria. 



Sphceria viridiatra Schw., Syn. X. Am., 1,537. 



The perithecia are immature, but to all outward appearance, this 



is, as stated in N. A. P., p. 748, Calonectria chlorinella Cke. 



Sphceria palina Fr. (in Herb. Schw.). 



Cytispora exasperans E. & E. in Proc. Acad. Xat. Sci. Phil., Xov. 1884, p. 

 360, is the same as this. 



Sec Starbiick, 1. c, p. 59, Sphceria palina Fr. , belongs to the 



Friesian genus Glutinium.
