 C. Kelseyi, E. & E. Proc. Acad. Nat. Sci. Phil., July, 1890, p. 240. 



Perithecia large, (|-1 mm.), rough, subglobose, regularly rounded 

 above, with a papilliform ,ostiolum, bursting through cracks in the 

 bark in elongated tufts, crowded and subconfluent, connected below 

 by a scanty grayish-black stroma. Asci cylindrical 170-190x15- 

 20 //, contracted below into a short, stipe-like base. Paraphyses fili- 

 form, abundant. Sporidia uniseriate, oblong-elliptical, straw-yellow, 

 becoming dark brown, contracted in the middle, with three principal 

 septa and several fainter ones (7-9 in all), muriform, 25-30 x 14-16 //, 

 ends at first obtusely pointed, finally rounded. The three main trans- 

 verse septa are the only distinct and decided ones, the others, both 

 transverse and longitudinal, being more or less indistinct and inter- 

 rupted. 



On Philadelphus Lewisiif Helena, Montana. 



This is with difficulty distinguished from C. Berberidis, Gray, 

 and might perhaps better be considered a var. of that species, from 

 which it seems to differ in its broader sporidia. The ascigerous peri- 

 thecia were accompanied by others., inclining more to ovate, with a 

 short, conic-cylindrical ostiolum, and filled with very minute (1^-2 x 

 \ //) sporules. 



C. Fraxini. E. & E. 1. c. (Plate 26) 



Perithecia globose, rough, black (white inside), \ mm. diam., 

 flattened above, with a papilliform ostiolum, seated on the surface of 

 the inner bark in compact clusters of about 8-12, and surrounded by 

 the ruptured epidermis. Asci cylindrical, p. sp. about 150 x 12-15 //, 

 with a short, stipe-like base and surrounded by numerous paraphyses. 

 Sporidia uniseriate or subbiseriate, ovate- oblong, constricted in the 

 middle, 5-6-septate and muriform, yellowish-brown, 25-30 x 10-14 //.
