(3-?) septate, 20-23 X 5-6», slightly curved, with a slender 
hyaline bristle-like appendage 15-30» long at each end; stylo- 
spores in ovate-conical scattered erumpent perithecia, with spor- 
ules shaped like the ascospores, only smaller (14-16 X 4-5 ) and 
lacking the bristle-like appendage. When the outer bark is 
stripped off, the perithecia either adhere to it or remain attached 
to the surface of the inner bark. 
DIAPORTHE AORISTA E. & E. 
On dead stems of Solidago sp., Newfield, N.J., July, 1896. (N. 
2. 3432) 
Perithecia scattered or gregarious, often 2—3 subconfluent, some- 
times subseriately arranged, slightly sunk in the unaltered sub- 
stance of the stem without any black circumscribing line, slightly 
raising the epidermis which is not discolored, or at most only 
slightly blackened where the perithecia stand close together, glo- 
bose, small (300-350); ostiola exserted, stout, roughish, conic- 
cylindrical, short; asci oblong-cylindrical, p. sp. 35-45 X 84; 
sporidia biseriate, oblong, uniseptate, slightly constricted, 2-4- 
nucleate, obtuse, hyaline, 11-13 X 4-4¥% pn. 
Differs from D. orthoceras (Fr.) in its rather smaller, only slightly 
buried perithecia and broader sporidia. WD. exercitalis Pk. also has 
narrower sporidia and distinctly seriate perithecia. 
DIAPORTHE LIGUSTRINA E. & E. 
On dead Andromeda ligustrina, Newfield, N. J., April, 1896. 
Perithecia thickly scattered, buried in the unaltered substance 
of the bark, about 1% mm. in diameter ; ostiola subconical, tuber- 
culiform or subglobuse, often seriate in longitudinal cracks in the 
bark, distinctly erumpent so as to appear like superficial perithe- 
cia; asci clavate-oblong, 50-60 X 8-10 w; sporidia subbiseriate, 
fusoid at first but when mature obtusely rounded at the ends and 
constricted in the middle, about 10 X 4 » or 9-II X 3%4-4¥% p. 
VALSA SOCIALIS E & E. 
On dead limbs of Salix cordata, Rooks Co., Kansas. (E. Bar- 
tholomew, no. 2099.) 
Stromata circinate or gregarious, cortical, not circumscribed, 
small (1-2 mm.), raising the epidermis into small pustules often 
arranged in a circle around acentral one ; perithecia buried in the 
unaltered substance of the bark, 14 mm. in diameter, abruptly 
contracted into slender necks with the minute black ostiola at 
first covered by a pale white disk, but finally erumpent though not 
exserted ; asci subcylindrical, about 60 X 6 » (p. sp.); sporidia sub-
