1). Saccardiana, Kze. >;cc. Sjll. 2430. 



Exsice. Kze. F. Set. 123. 



Peritheeia 2-6 together, siibcircmate, buried in the unaltered 

 inner bark without any circumscribing line, about oOU tj. diam., with 

 their stout, conical or conic-cylindrical ostiola erumpent in a loose 

 fascicle together. Asci p. sp. oblong-fusoid, 40-45 x 8-9 /*. Sporidia 

 biseriate, oblong-fusoid, 4-nucleate, uniseptate and very slightly con- 

 stricted, 10-12 x 3-3 , (15 x 4|-5 p 7 Sacc.). 



On small, dead limbs of elm, London, Canada (Dearness). 



The small groups of perithecia lie close together, almost filling 

 the bark. There is no distinct apieulus at the ends of the sporidia,. 

 nor do we see any in Kunze's specimens in which the sporidia are a 

 trifle larger, 10-14 x3| -4 /2. The latter also show a distinct, circum- 

 <cribing line in the older and thicker hark, but none on the smaller 

 limbs.

 Diaporthf. impidsa, Sacc. Syll. 2395. 



Stroma depre&sed-sul )conical, J-J cm. diam., formed of the scarce- 

 ly altered substance of the bark, with a black, limiting line penetrat- 

 ing the wood. Perithecia 8-12, subcircinate, J-J mm. diam., with 

 -lender necks, the obtusely-conical, finally umbilicate-collapsing ostiola 

 erumpent through a small, grayish-black disk rather loosely surrounded 

 by the ruptured epidermis. Asci clavate-cylindrical, p. sp. about 

 40 x 6 fjL. Sporidia biseriate, fusoid, uniseptate, nucleate, hyaline, 

 hardly constricted, 16-20 x 3-3| t u, 



On dead branches of Pyrus Americana, Adirondack Mts. r 

 N. Y. (Peck), on Pyrus sambucifolia, California (Harkness).

Stroina valsoid. Acervuli scattered, small, consisting of 5-6 

 perithecia lying in subcircinate groups buried in the surface of the 

 wood and covered by the slightly raised epidermis, which is finally 

 ruptured. Perithecia subglobose, about J mm. diam. Ostiola erum- 

 pent in a fascicle together, for some time covered by the epidermis,
