Stronia Mack, carnose, 2-3 nun. across, its convex surface thickly 

 covered with the minute, parasitic ? perithecia, which arc subglobose, 

 about l(>f>// diam., clothed laterally with stout, black, spreading spine- 

 2/>-40x 7 /^. Ostiolmn either smooth and subpapilliform or more or 

 less distinctly radiate-silicate. Asci oblong clavate, 45-55x12 /i 

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

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

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

 septate and submuriform, 12-15x4-5 //. Accompanied by Cornularia 

 Persicce. (Schw .) The crowded perithecia bear a general resemblance 

 to those of Ottilia morbosa, (Schw.), from wliich, however, this is <|uite 

 distinct. 



Parasitic ? on the tubercular, erumpent stronia of some DUitrypc / 

 on dead limbs oi' wild plum (Pritnus), London, Canada (Dearness). 



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

 and in the bark beneath it are buried the abortive perithecia of the 

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

 homonomous species C. *et<>s<t, Winter, which was overlooked.
