The above diagnosis is from Fries. We have riot seen the New 

 York specimens, but specc. from Plowright (England) have asci 60- 

 7~>x6-8 //. Sporidia filiform, 40-50 x 1-1 -| //. Perithecia elliptical, 

 rather obtuse, 1-1 J mm. long by \ mm. broad, depressed above when 

 young, covered by the epidermis. The specc. are evidently not mature.

Perithecia scattered and lying in various directions, elliptical, 

 oblong or short-linear, black, prominent, small (|-1 J mm.); lips swollen, 

 convex, leaving a narrow fissure between them, covered by the black- 

 ened epidermis, but when this falls away, becoming superficial. Asci 

 cylindrical. Sporidia filiform, hyaline, not thickened at the apex, 

 about as long as the asci.

Hypophyllous, at first standing singly along the midrib, at length 

 confluent, forming a continuous black line, erumpent, convex, black, 

 marked above with a distinct, longitudinal cleft, finally open so as to 

 expose the pale yellow disk, 1-1 J mm. long, \~\ mm. broad. Asci 

 clavate-oblong, 60-90x12-15 <JL, sessile, obtusely pointed above. 

 8-spored, with slender, filiform, undulate paraphyses. Sporidia fili- 

 form, clavate-thickened and bent at the tips, which are about 2 JJL thick.

The measurements are from Linhart's specc. and are about the 

 same as those given by Dr. Rehm.
