above, short- elliptical, l-2-nucleate,5-7 x 4-6//, hyaline or yellowish- 

 hyaline. 



Closely resembles outwardly Patellaria ferruginea C. and E., but 

 the sporidia are different. In the specc. on Eupatorium, the sporidia 

 correspond to the larger measurements and are mostly 2-nucleate. 



Karschia sphaerioides E. & E. 



On rotten, decorticated oak limb, Newfield, N. J. March 26, 1893. 



Ascomata gregarious, sessile, 150-200//. diam., black, margin in- 

 curved and irregularly lacerate- toothed, more strongly incurved when 

 dry so as to hide the dull white disk, often clothed outwardly, espe- 

 cially when young, with a few black spreading, bristle-like hairs, 

 which also overspread the surface of the wood. Asci oblong- clavate, 

 short stipitate, 25-30 x 8-1 0/jt, and, like the stout paraphyses, of a 

 greenish-yellow color. Paraphyses 2-3-septate, slightly enlarged 

 above and often constricted at the upper septum. Sporidia biseriate, 

 ovate-oblong, pale brown, uniseptate and slightly constricted at the 

 septum, 8-10x 3-3j:'. 



Differs from the other species in its margin so strongly incurved 

 as, in the dry state, to hide the disk almost entirely and thus give 

 the appearance of a pyrenomycete. 



Blitrydium Symph o ricarpi E. & E. 



On dead twigs of Symphoricarpus vulgaris, Rockport, Kansas. 

 Aug., 1893. (Bartholomew). 



Scattered, erumpent-superfieial, slaty-black, £-1 mm. diam., dis- 

 coid, with a narrow, erect margin, outside and disk rugulose and 

 when young clothed with a few, short, scattering, pale, glandular 

 hairs. Asci, oblong, subsessile, 120-130x30-35,", paraphysate, 

 8-spored. Sporidia biseriate,broad fusoid-oblong or oblong-elliptical, 

 a little narrower below, multiseptate-muriform, yellow-browm, 

 35-40 x 16-24,". 

 Stictis compressa E. & E. 



On dead limbs of Carpinus and Ostrya Virginica, London, Canada. 

 (Dearness). 



Ascomata entirely buried in the wood, laterally compressed, 1-2 

 ram. long, acute at each end, grayish-black. Ostiolum erumpent 

 through the bark forming a minute, white tubercle with an olive- 

 colored center but, at least when young, without any distinct open-
