SACCARDOELLA, Speg, 



Mich. I, p. 461. 



Perithecia large, immersed, coriaceo-carbonaceous. Ostiolum 

 papilliform. Asci cylindrical, 8-spored, paraphysate. Sporidia elon- 

 gated-fusoid, setigeroiis-appendiculate, multiseptate, hyaline. 



S. Canadensis, E. & E. (in Herb.) 



Perithecia solitary, ovate,' | x | mm. sunk in the inner bark, of 

 light-colored, waxy consistence inside, the apex raising the epidermis 

 into slight pustules barely perforated by the papilliform ostiolum. 

 Asci cylindrical, short-stipitate, 200-280 x 10/i, with abundant filiform 

 paraphyses. Sporidia overlapping-uniseriate, fusoid-cylindrical, about 

 15-septate, 40-60 X S-d^fi, at first much smaller, uniseptate and setig- 

 erous at each end. 



On bark of Gratcegus, London, Canada (Dearness). 



JULELLA, H. Fab. 



Spher. Vaucluse, p. 113. 



Perithecia simple, subglobose, typically covered, but (in the 

 American species) suberumpent. Asci 1-2-spored. Sporidia large, 

 clathrate-reticulate, yellowish. 



J. monosperma, (Pk.) 



Sphesria monosperma^ Pk. 28th Rep. p. 79, pi. 2, figs. Z^Z9- 

 Julella Tnonospernta, Sacc. Syll. 3874. 



Perithecia scattered, semiimmei'sed, ovate-hemispherical, black, 

 about J mm. diam. Ostiolum tubercular-papilliform, flattened above 

 and soon pierced with a large, round opening. Asci clavate-oblong, 

 75-150x30-40 ji, with abundant, filiform paraphyses. Sporidia only 

 one in an ascus, densely clathrate-fenestrate, and nearly filling the 

 ascus, yellowish-hyaline. 



On decorticated birch wood, Forestburg, N. Y. (Peck), on decor- 

 ticated bleached wood, Washington (Suksdorf). 



In the Washington specc. the perithecia are rather smaller (| mm. 

 diam.), and the sporidia also are mostly not over 100 x 25 pL, but other- 

 wise they do not seem to differ from the New York specc. sent by 

 Peck. The Washington specc, however, are rather old, and the upper 

 part of the perithecia is broken away so that the ostiolum can not be 

 seen. J. Kellermanni, mentioned in Cooke's Synopsis Pyrenomy- 

 cetum (5137 bis), is Kellermannia yucccegena, E. & E., which belongs 

 in the SphceropsidecB (see Journ. Mycol. I, p. 158).
