Perithecia scattered, small (160-170 //), buried in the wood, 

 except the narrow, compressed, erurapent ostiolum. Asci subcylin- 

 drical, 90-100x10-12 /z (spore-bearing part 75-80 // long), sur- 

 rounded and overtopped by abundant, thread-like, paraphyses. Spo- 

 ridia biseriate, fusiform, 3-septate, hyaline, slightly curved and mostly 

 constricted at the middle septum, 15-20 x4-5 //. 



On decorticated, decaying stems of Rhus radicans, Newfield, N. J. 



Var. stenocarpum, E. & E., on decorticated oak limb, Newfield, 

 N. J., has sporidia about 20 x 3 fi. Var. Asteris, on dead stems of 

 Aster, Louisiana (Langlois 1440) has sporidia 25-30 x 5-6 /i, unisep-

Perithecia closely gregarious, small (350-500 p.), sunk in the 

 wood, erumpent, conical, clothed with a slight, tawny-ferruginous, 

 pulverulent tomentum. Ostiola naked, black, subterete or compressed. 

 Asci clavate, 150-190 X 15-18 ju. Sporidia crowded, subfusiform, at 

 first biconical and uniseptate, then triseptate, dr quadrinucleate, con- 

 stricted in the middle, hyaline, 30^0 x 7^-10 //.

Perithecia gregarious, subglobose with their bases slightly sunk 

 in the wood, mostly a little less than \ mm. diam., ostiolum forming a 

 narrow ridge entirely across the perithecia, and thus giving them the 

 appearance of a Hysterium. Asci cylindrical, 60-70 x 5-6 //, with 

 abundant paraphyses. Sporidia biseriate, fusoid, nearly straight, 

 3-septate, smoky-hyaline, 14-16 x 3 fi, the next to the upper cell 

 swollen.
