On dried branches. > [Mid. Carolina.] 



Pustules 2-3 lines broad, at length by tlie decay of the bark free ; stroma 

 white below, darker above, being almost obliterated by tlie crowded necks of 

 the small perithecia ; ostiola rather rugged, globose or beaked on the same 

 stick. — xV7./.^. Sporidia (•000G--0007 in.) -Olo-'OIZ m.m. Perithecia very 

 numerous in each pustule, deeply imbedded in a very white stroma, when 

 cut across horizontally, a very well defined black line is seen which arises 

 from the wood surrounding the perithecia being blackened, thereby causing 

 the appearance of a couceptaculum, but there is not really any.— P. C. 



J Sporidia appendiculate. 



2502. Valsa taleola. Fr. '' Ciliated oak Yalsa." 



Loosely circumscribed; stroma cortical ; perithecia crowded 

 in the centre; disc white; ostiola even, immersed, punctiform ; 

 sporidia oblong, very obtuse, uniseptate, with cilia on each side of 

 the septum and at either extremity. — Fr. S. V. S.p. 411. FcJd.

On oak branches. Common. [Low. Carolina.] 



Sporidia uniseriate, seldom biseriate, colourless, or pale sea-green, obtuse, 

 constricted in the middle, furnished with four cilia, one proceeding from 

 each pole, and one from the middle of each side ; endochrome usually gran- 

 ular (■0008-'0012 in.) ■02-'03 m.m. long. {Sometimes when the endochrome 

 is oleaginous, and not granular, the appearance of the sporidia is quite dif- 

 ferent.— F.C. 



2503. Valsa thelebola. Fr. " Tailed Alder Yalsa." 



Pulyiniform or conical, depressed or subtruncate ; asci oblong ; 

 sporidia biseriate, amber-coloured, with a greenish tint or hya- 

 line, slightly curved, obtuse at the extremities, commonly ciliate 

 at each end, uniseptate. — Curr. Linn. Trans, xxii. p. 280, t. 48,
