Stroma black, carnose, 2-3 mm. across, its convex surface thickly 

 covered with the minute, parasitic ? perithecia, which ai-e subglobose, 

 about 165 ft diam., clothed laterally with stout, black, spreading spines 

 25-40x7 /i. Ostiolum either smooth and subpapilliform or more or 

 less distinctly radiate-sulcate. Asci oblong clavate, 45-55x12 fi 

 (p. sp.), contracted below into a narrow, stipe-like base. Paraphyses 

 longer than the asci, evanescent. Sporidia biseriate, subrhomboidal- 

 oblong, hyaline and multinucleate at first, becoming yellowish, 3-5- 

 septate and submuriform, 1 2-15 x 4-5 /i. Accompanied by Cornulariu 

 Persiccp,, (Schw.) The crowded perithecia bear a general resemblance 

 to those of Otthia morhosa, (8chw.), from which, however, this is quite 

 distinct. 



Parasitic ? on the tubercular, erumpent stroma of some Diatrype^ 

 on dead limbs of wild plum (Primus), London, Canada (Dearness). 



The stroma is carnose and black inside and out, 2-3 mm. diam., 

 and in the bark beneath it are bui-ied the abortive perithecia of the 

 Diatrype. The specific name has been changed on account of the 

 homonomous species C. netosa, Winter, which was overlooked.

Perithecia crowded-cespitose, globose, smooth, brownish-black, 

 subastomous. Asci broad-cylindrical, with a nan-ow base, 8-spored, 

 110-125x14-16//. Sporidia uniseriate or partly biseriate, oblong- 

 clavate, narrowed below, constricted in the middle, 3-6-septate, with 

 an imperfect, longitudinal septum, honey -yellow, 19-23x7-9 fi.

The specimen in Herb. Schw. is too poor to allow one to express 

 any opinion as to what it may be.

Perithecia erumpent, generally in elliptical tufts, rather large 

 (about \ mm. diam.), black or blackish, of irregular shape and subcir- 

 cinately arranged, the lower half sunk in a fiirfiiraceous, dark tomen- 

 tum. Asci 112-120x15-20 //, subsessile, paraphysate, 8-spored. 

 Sporidia uniseriate, clavate-elliptical, hyaline and with a broad, hyaline
