The Canada specc. agree perfectly with the foregoing description 

 (which is mostly from Winter's Pilze) and with the specc. in Sacc. M. 

 Veneta and Desm. PI. Or. 1254, as well as with German specc. in our 

 Herb., only they have the perithecia rather smaller (not over | mm.). 

 This is the size given them in the Syll., and in Winter's Pilze, but the 

 specc. in the Exsiccati quoted have the perithecia ^-1 mm. diam.

Stromata mostly numerous and standing close together, covered 

 by the epidermis and forming hemispherical pustules with their bases 

 sunk in the scarcely altered substance of the inner bark, crowned with 

 a small, erumpent disk, surrounded by the ruptured epidermis. Peri- 

 thecia 6-8 in a stroma, tolerably large, globose, crowded in a circular 

 group, nearly erect, black, the obtuse, conical ostiola united in a small, 

 concave, brownish-black disk but slightly prominent. Asci cylindrical, 

 sessile, 8-spored, 100-120 x 7-8 fi, paraphysate. Hporidia uniseriate, 

 broad elliptical, rounded at the ends, straight, black, 8-12 x 7-8 //. '
