The measurements of Winter and Rehm, both from Fiickel's specc, 

 show quite a variation. See. Dr. Rehm the Delaware specc. differ 

 from his specimen from Fiickel, in their smaller and less crowded peri- 



thecia. 



V. papyriferse, (Schw.) 



Sphczria papyriferce, Schw. Syn. N. Am. 1375. 

 Vaha papyriferce, Cke. Syn. 1668. 



Gregariously surrounding the branches, and strongly raising the 

 epidermis, which is stellately ruptured, revealing the pustules with 

 their black, rough, truncate disks protruding; the short, irregular- 

 shaped, umbilicate ostiola at length emerging. Perithecia few, rather 

 large, globose, enclosed in a milk-white stroma, with a black exterior. 

 The small, prominent pustules roughen the branch.

Symbolae, Nachtr. I, p. 33. 



Stroma none. Perithecia buried in the wood, scattered or 

 crowded, with the large, sphseroid or pezizoid ostiola erumpent. Asci 

 narrow clavate-cylindrical, 8-spored, with abundant, filiform paraph) rses. 

 Sporidia uniseriate, or biseriate above, cylindrical or 1- or more-sep- 

 tate. Xylogenous or corticolous. 



Kalmusia is included as a subgenus. 



* Sporidia continuous. 



E. inacrostoma, Fckl. Symbolae, Nachtr. I, p. 322. 



Perithecia scattered or crowded in irregular groups, entirely 

 buried in the wood, without any visible stroma, about j mm. diam., 

 abruptly narrowed above into a stout, straight neck, about as long as 

 the diameter of the perithecium, the swollen apex subglobose-en large d 

 to nearly or quite the diameter of the perithecium itself, and semi- 

 erumpent; papilliform at first, then perforated with a round opening. 

 Asci clavate-cylindrical, 80-110x6-7 p. (p. sp. about 60 p. long), sur- 

 rounded with abundant, filiform paraphyses. Sporidia 8 in an ascus. 

 overlapping-uniseriate or subbiseriate above, oblong-cylindrical, ob- 

 scurely 2-nucleate, olive-brown, straight or very slightly curved, 8-11 

 x 3-3J p.
