 hemispherical, with the margin incurved and toothed, rough verru- 

 cose-squamose outside, pale yellow inside, substance soft-car nose. 

 Asci clavate-cylindrical, stipitate, p. sp. 70-75 x 15-20/*. Paraphy- 

 3es filiform, longer than the asci. Sporidia irregularly crowded in 

 the asci, elliptical, smooth and hyaline at first, pale-brown and 

 longitudinally striate when mature, 15-20 x 9-11 //.. 

 Cenangella abietina E. & E. 



On bark of dead Abies. Newfoundland. Waghorne. 



Ascomata erumpent-superficial, gregarious, black, orbicular, 

 about ? mm. diam. with the margin thin and suberect. Asci 

 clavate-cyclindrical subsessile, 60-75 x 12 //, 8-spored. Sporidia 

 biseriate, ovate-elliptical, yellowish, becoming brown, 2-nucleate, 

 becoming uniseptate, 12—18 x 6-7 //.. 



Patellea hysteric-ides E. & E. 



On weather-beaten pine lumber. Rooks Co., Kansas. E. 

 Bartholomew. 



Ascomata erumpent-superficial, i-i mm. diam., black, the opposite
