Stroma variable, erumpent. often rudimentary, orbicular, about 1 

 mm. diam., or by confluence larger and variable in shape. Perithecia 

 vSunk in the stroma, finally emergent and often quite superficial, stro-

wliite inside. Asci inflated-clavate. paraphysate. 8-spored, 75-100 x 

 18-25 /A. Sporidia imperfectly biseriate. inequilaterally elliptical, 

 hyaline, continuous, 18-38x8-15 JJL. 



On dead limbs of various deciduous trees and shrubs, throughout 

 the U. S. and Canada. Common and variable. See paper in Proc. 

 Acad. Nat. Sci. Phil., referred to above. The forms with scattered 

 perithecia (var. simplex) have been removed to Physalospora. 



Repeated observation convinces us tliat it would be simply al> 

 -urd to separate the various forms above quoted as distinct species. 

 Without knowing the host, it would be impossible to separate them. 

 Sphc&ria Hibisci, Schw.. and S. Crafnf//. Schw., which in the 

 paper above referred to were interrogatively included as synonyms, 

 prove on examination to In- difl'nvnt. r'igs 1 and '2. PI. 36, represent
