with abundant paraphyses. Sporidia irregularly crowded, broad, 

 fi.soid-oblong, slightly curved or a little bulging on one side, nearly 

 hyaline and uniseptate at first, becoming deep, clear brown and 7-sep- 

 tate, three of the septa close to each end, 50-60 x 15-20 /i. 



On a dead hickory limb, Poughkeepsie, N. Y. (Gerard), on dry, 

 decaying oak wood, Newfield, N. J. . 



The general aspect is the same as that H. vulvatum, Schw., or 

 H. lineolatum, Cke., but the sporidia are different. Gerard (1. c.) 

 figures the sporidia as uniseriate with the septa at equal distances, but 

 in the specc. sent by him they are as stated above. 



H. eumorphum, Sacc. Mich. II, p. 40. 



Perithecia loosely gregarious, decidedly superficial, so that the 

 base is not entirely adnate, regularly navicular, straight, acute at each 

 end, 1| x \ mm., becoming black, dehiscing with a lanceolate opening 

 and exposing the reddish disk; lips smooth, obtuse. Asci cylindrical, 

 very short-stipitate, 150-160x15 p, rounded at the apex, 8-spored, 

 surrounded with conglutinated, filiform paraphyses with dark-colored 

 tips. Sporidia obliquely uniseriate, fusoid-oblong, subobtuse at the 

 ends, mostly curved, 30-38 x 11-14 //, with three broad septa, not con- 

 stricted, guttulate, dark brown, becoming nearly black. 



On bark, South Carolina (Ravenel). 



Agrees (sec. Cooke) with specc. of Hysterium, biforme, Fr. Scler. 

 Suec. (not Duby), but not with the diagnosis of H. biforme as given 

 by Fries. We have not seen this, but the description tallies well witli 

 that of Tryblidium nifulum, (Sprengel.) 



H. thujarum, C. & P. Cke. Disc, of the U. S. p. 33. 



Subgregarious, superficial. Perithecia elliptical, acuminate, ele- 

 vated, almost naviculoid, longitudinally striate, black; lips prominent, 

 closely connivent. Asci cylindrical. Sporidia broadly lanceolate, 

 obtuse, 3-5-septate, brown, 38-40 x 10-12 p. 



On Thuja, New York (Peck). 



H. depressum, B. & C. Cke. Disc, of U. S. p. 34, Grev. IV, p. 10. 



Elongated, rough with little granules, depressed, disk extremely 

 narrow. Asci clavate. Sporidia cymbiform, with about 5 septa., some- 

 times bulging in the center on the convex side, 30 p long. 



On dry wood, Carolina (Curtis). 



H. versisporum, Ger. Bull. Torr. Bot. Club, VI, p. 78. 

 Perithecia scattered, minute, black, smooth and shining, elliptical ;
