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

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

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

 thecia.

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.

Stroma none. Perithecia buried in the wood, scattered or 

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

 narrow clavate-cylindrical, 8-spored, with abundant, filiform paraphyses, 

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

 tate. Xylogenous or corticolous. 



Kalmusia is included as a subgenus. 



* Sporidia continuous. 



E. raacrostoma, Fckl. Symbolse, Nachtr. I, p. 322. 



Perithecia scattered or crowded in irregular groups, entirely 

 buried in the wood, without any visible stroma, about J mm. diaui., 

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

 the diameter of the perithecium, the swollen apex subglobose-enlarged 

 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, 80-110 x 6-7 fi (p. sp. about 60 ^ 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 3-3^ fi.
