elongated-clavate, 100-112 x 10-12 //, with filiform paraphyses. Spo- 

 ridia filiform, nearly as long as the asci, multinucleate, becoming 

 multiseptate, about 1| // thick, hyaline. 



On dead wood of Abies nigra, Sandlake, N. Y. (Peck), on decay- 

 ing wood of white cedar {Cupressus thyoides), Newfield, N. J. 



Differs from CI. degenerans in the black, crustose subiculum and 

 sporidia thickened at the apex. 



CI. Empetri, (Rostr.) 



Sporomega Empetri, Rostr. Fungi Groenl. p. 543. 



Perithecia epiphyllous, brown-black, elongated, straight or flexu- 

 ous, rather thick, opening with a longitudinal cleft; lips finally remote. 

 Asci clavate, attenuated towards the apex, 80-90x18 //, 8-spored. 

 Sporidia filiform, hyaline, simple, joined at the base, 60-64 x 2 /i. 



On dry leaves of Empetrum nigrum, Egedesminde, Greenland. 



CI. grisea, (Schw.) 



Hysterium griseum, Schw. Syn. N. Am. 2097. 

 Sporomega grisea, Cke. Disc. U. S. p. 36. 

 Exsicc. Ell. & Evrht. N. A. F. 2d Ser. 2377. 



Perithecia at first entirely covered, but visible through the trans- 

 parent epidermis, grayish-black, elliptical, flat, obtuse, about 1 mm. 

 long, at length opening with a longitudinal fissure. Asci clavate- 

 cylindrical, 65-75 x 6-7 /i, with filiform paraphyses longer than the 

 asci and branched above. Sporidia 8 in an ascus, filiform, 30-35 x 1 /i, 

 multinucleate. 



Common on dead stems of Smilax, Pennsylvania and New Jersey. 



CI. Andriimedse, (Schw.) 



Hysterium AndromedcE, Schw. Syn. N. Am. 2090. 

 Sporomega Andromeda, Duby, Hyst. p. 48, tab. II, 'fig. 24. 

 Exsicc. Ell. N. A. F. 155. 



Perithecia lanceolate, ovate or suborbicular, often elongated to 

 J cm. in length, lying in various directions on the matrix, at first cov- 

 ered by the epidermis which is raised into elongated swellings, as if 

 some larva had burrowed beneath, soon splitting in a narrow crack 

 along the apex of the perithecium, and finally partially opening so as 

 to expose the waxy-white disk which at length becomes black. Asci 

 narrow-clavate, 75-85x8-10 fi, 8-spored, with paraphyses slightly 

 thickened and often branched at the tips. Sporidia filiform, nearly as 

 long as the asci. 



On dead stems and branches of Azalea viscosa and Andromeda
