flat, with au irregularly shaped openiug. Asci clavate- cylindrical, 

 60-70x7-8,". (p. sp. 30-35,v, long;, paraphysate, 8-spored. Sporidia 

 biseriate, cylindrical, smoky yellow-brovvn, slightly curved, obtuse, 

 10-12x2-3//. Stroma circumscribed by a black line, which does 

 not penetrate the wood. This can hardly be the Sphceria dolom Fr., 

 said by Schw. to occur on Celadrm. It is certainly different from 

 the spec, so labeled in Sydow's Mycotheca Marchica. 

 Anthostoma formosum E & E. 



On bark of dead Geltis occidentalis, Rockport, Kansas, June, 

 1894 (Bartholomew, No. 1,492). 



Stromata scattered, cortical, thick-convex, 2-4 mm. diam., orbicu- 

 lar or elliptical, formed from the scarcely altered substance of the 

 bark. Perithecia 12-20 buried in the stroma but not penetrating 

 to the wood, ovate-globose, with thick, cartilagino-membranaceous 

 walls, black and shining inside, about 1 mm. diam., their slender 

 necks converging, their stout, conic- cylindrical ostiola with smooth 

 rounded tips, erumpent in a close fascicle and projecting, when fully 

 developed for 1 mm. or more, or quite as often, merely raising and 

 rupturing the epidermis, but scarcely rising above it. Asci cylin- 

 drical, stipitate, paraphysate, p. sp. 60-70x4-5//. Sporidia unise- 

 riate, oblong, dark brown (subhyaline and nucleate at first), 

 straight, obtuse, 7-10x3-4//. 



Anthostoma micrcecium E. & E. 



On dead limbs of Asimina triloba, Nuttallburg, West Va., Feb. 

 1894 (L. W. Nuttall). 



Stroma cortical, faintly circumscribed, 1-1 2 mm. diam., orbicular, 

 convex. Perithecia 4-8 in a stroma, globose, minute (200-250/'), 

 circinate, necks slender, short, converging, with the minute, papilli- 

 form ostiola erumpent in a small, black, hemispherical disk, which 

 barely pierces the pustuliform-elevated epidermis, and is closely em- 

 braced by it. Asci cylindrical, 80-110 x 8-10/*, paraphysate 8-spored. 

 Sporidia uniseriate, elliptical, brown, continuous, 2-nucleate, 12-14 

 X 6-7//. 



Distinguished by its very small stroma and perithecia. 

 Diatrypella prunicolaE& E. 



On dead limbs of Primus Pennsylvaniea, Alcove, N. Y., Feb. 

 1894 (C. L. Shear, No. 298, partly). 



Stroma seated on the inner bark, convex- hemispherical, 3-4 mm.
