the asci and lJ-2/i thick, multiseptate, soon separating into joints 

 3-4 II long, (Stictis or Schizoxylon). 



0. staphylinus, E. & E. 1. c. 



Perithecia small, covered by the iibers of the wood through which 

 project the short, straight, roughish, black, rostellate ostiola. Asci 

 linear, 120-150 x4 //, accompanied by filiform paraphyses. Sporidia 

 8 in an ascus, filiform, yellowish, nucleolate, and about as long as the 

 asci. 



On the same stems is a Sphmropsis with oblong, depressed peri- 

 thecia, and sporules 18-20 x8-9 a; also other small perithecia partly 

 covered by the fibers of the wood, and containing numerous elliptical, 

 subfuscous, 3 X 2, /i sporules. 



On decorticated stems of Staphylea trifoUa, West Chester, Pa. 



The specc. are scanty and poor, so that we can noi verify the 

 original diagnosis, and the species must be considered doubtful. Pos- 

 sibly not distinct from O.fruticum, (Rab. & Desm.).

Perithecia gregarious, sometimes disposed in lines, soon free, glo- 

 bose, black, smooth, shining, scarcely papillate, 250-270 n diam., at 

 length collapsed. Asci clavate-cylindrical, p. sp. 80-90x12 fi, pat- 

 aphysate, stipitate, 8-spored. Sporidia cylindrical, subattenuated at 

 each end, nearly straight, yellowish-brown, multiseptate and often con- 

 stricted at the septa, 75-80 x 4-5 fi. 



On dead stems of Ambrosia trifida, New York, New Jersey, 

 Pennsylvania, Ohio and Kansas. 



Distinguished from O. anguillides by its much coarser sporidia. 



0. claviger, Hark. Bull. Oal. Acad. Feb. 1884, p. 46. 



Perithecia globular, with a papillate ostiolum, gregarious or scat- 

 tered, erumpent, then free, J-l mm. diam., at first filled with minute 

 spermatia. Asci linear-clavate, 8-spored, 210 x 14 [i. Sporidia fili- 

 form, nucleate, pale brown, 20-25-septate, the upper third somewhat 

 swollen and constricted, 140 x 7 //.
