briefly stipitate, 110-115x14 /A paraphysate, 8-spored. Sporidia 

 hiseriate or obliquely uniseriate, fusoid, 28-30 x 8-10 JJL, straight or 

 slightly curved, 5-septate, 6-nucleate, deep brown, occasionally one 

 cell divided by a longitudinal septum. 



On dead branches of Lonicera Tatar ica, Lyndon ville, N. Y. 

 (Fairman 179), and on loose hanging bark of grape vines, Newfield, 

 X. J. (issued in N. A. F. 1695 as L. sexnudeatum, Cke.) 



The specimens from both these localities have the perithecia 

 smaller than in the type and correspond to L. vagans, H. Fabr., which 

 can hardly be more than a var. of L. pseudomacrostonium. 



L. Thujse, E. & E. (in Herb.) 



Perithecia scattered, buried, except the erumpent, rounded apex, 

 with the narrow, compressed ostiolum extending J to \ way across. 

 Asci clavate- oblong, 50-70x12-15 <JL. Sporidia biseriate, oblong- 

 fusoid, 3-septate. slightly curved, obtuse, yellowish-brown, 14-16x3- 



4. 



On foliage of Thuja Occident alls partly dead but not yet fallen, 

 Potsdam, N. Y. and London, Canada. 



L. triseptatum, Pk. seems to differ in its linear asci and obtuse 

 sporidia. 



L. magiiatum, C. & P. 29th Rep. N. Y. State Mus. p. 64. 



Perithecia subgregarious, semiimmersed, globose, rather large, 

 somewhat thin and fragile, pitchy-black. Ostiola short, compressed. 

 Asci cylindrical or clavate, Sporidia biseriate, lanceolate, constricted 

 in the middle, 3-5-septate, 50-60 // long. 



On decaying wood, New York (Peck). Resembles L. macrosto- 

 mum in habit. 



L. Laiigloisii, E. & E. 1. c. 



Perithecia gregarious, subconical, f mm. diam., about half buried 

 in the bark, the projecting part dull black, roughish, with a narrow, 

 more or less compressed, prominent ostiolum. Asci subcylindrical. 

 110-120 x 12-15 //, with abundant paraphyses. Sporidia mostly 

 biseriate, fusoid, 3-septate and slightly constricted at the septa, brown, 

 slightly curved, each cell with a large nucleus, 34^40 x 7-8 JJL. 



On bark of decaying Salix, Louisiana (Langlois). 



L. stenostomum, E. & E. Bull. Torr. Bot. Club. X, p. 89. 



Exsicc. EH. N. A. F. 1345. 



Perithecia scattered, globose, 350 n diam., covered by the fibers
