342 PKOCEEDINGS OF THE ACADEMY OF [1894. 



sp. 25-30x4;/.. Sporidia biseriate, allautoid, hyaline, moderately 

 curved, 8-10x1^-2//. 



Eutypella carpinicola E. &. E. 



On dead limbs of Carpimis Americana, Alcove, N. Y., Oct. 1893 

 (C. L. Shear, No. 190). 



Stromata cortical, flat, subconfluent, 11-2 mm. diam. , formed 

 from the scarcely altered, superficial layer of the inner bark, below 

 which the substance of the bark and surface of the wood i.s uniformly 

 blackened. Perithecia subcircinate, 3-6 together, ^-f mm. diam., 

 with thick, coriaceous walls, their short necks erumpent in a small, 

 flattened, tubercular, black disk, which pierces the papilliform- 

 elevated epidermis, and appears like a small black speck on its surface. 

 Ostiola erumpent through the disk, broad, flat, soon stellately cleft. 

 Asci slender- clavate, p. sp. 40-50x5//, or including the slender 

 stipe, 80-100/'. long, paraphysate, 8-spored. Sporidia biseriate, 

 allantoid, yellowish, slightly curved, obtuse, 8-10x2//. 



The perithecia lie in the superficial layer of the inner bark, and 

 when the epidermis is pulled off", this layer and the imbedded peri- 

 thecia adhere to and come off" with it. The perithecia are then seen 

 to be surrounded by a thin white layer apparently formed from the 

 substance of the bark. 



Calosphaeria cornioola E. & E. 



On dead limbs of Cornus asperifolia, Rock port, Kansas, May, 

 1894 (Bartholomew, No. 1,470). 



Perithecia scattered or loosely collected in subvalsiform groups of 

 3-5, minute, 200-250// diam., buried in the unchanged substance 

 of the inner bark, covered by the epidermis which is raised into 

 little pustules and pierced by the papilliform ostiola. Asci clavate, 

 27-32x6-62//, rounded above and gradually narro^ved to the base. 

 Paraphyses linear, nucleate, much longer than the asci. Sporidia 

 biseriate, cylindrical, hyaline, curved, obtuse, 10-12x2/7.. 



Differs from C. minima Tul. (also on Cornus) in its sporidia twice 

 as long and rather broader. The scattered mode of growth is like 

 that of C. microtheca C. & E. 



Endoxyla aoericola E. & E. 



On rotten maple wood, Granton, Ontario, Canada, Jan. 1894 

 (Dearness, No. 2,235). 



Perithecia scattered or subvalsiforra-aggregated, globose, black.
