Fenestella leucostoma E. & E. 



On dead limbs of A/ mis, Bay of Islands, Newfoundland, Oct., . 

 1897 (Rev. A. C. Waghorne, no 3 1 i b ). 



Stromata scattered, orbicular, truncate-conic above, convex be- 

 low, about 1.5 mm. in diameter, adnate to the inner surface of the 

 epideimis and separating with it, as in Valsa leucostoma (Pers.), 

 from which externally this can hardly be distinguished : perithecia 

 4-6 in a stroma, small (150-200//), the minute black papilliform 

 ostiola piercing the minute round snow-white disk which perforates 

 the epidermis and raises it into pustules : asci cylindical, briefly 

 attenuate-stipitate, obscurely paraphysate, 8-spored : sporidia uni- 

 seriate, oblong-elliptical, yellow-brown, 5-7-septate, constricted in 

 the middle, obtuse, 20-27 x 12-13 /i.

plane or slightly concave, black, subangular ; ascigerous cells ob- 

 scure: asci cylindrical, short-stipitate, obscurely paraphysate (?), 

 about 80 x 12/i: sporidia mostly biseriate, clavate-fusoid, 5-6- 

 septate, constricted at the middle septum, hyaline, 20-27 X 5-6 ,«• 



The ascigerous cavities were not satisfactorily made out, but 

 the character of the stroma is that of the Dothideaceae.

Ascomata scattered, erumpent, convex, dull watery-white, .3$- 

 .5 mm. in diameter, closely embraced by the ruptured epidermis, 

 concave when dry, with the margin darker and irregularly bent : 

 asci oblong, 60-70 x 12-15 P* including the short, abrupt stipe: 

 paraphyses stout, slightly thickened at the tips: sporidia 1-2- 

 seriate, globose or ovate-elliptical, 7-10 (mostly about 8 «) x6-8 ft,
