 black, unibilicate, looking out from cracks in the epidermis.

Differs from Calosphwria in its many-spored asci, which, in some 

 of the species, are flattened, and, as it were, coronate at the apex. The 

 perithecia lie on the surface of the inner bark, covered only by the 

 epidermis.

Perithecia crowded into little groups, globose, seated on a dark 

 spot. Asci obovate, stuffed with numerous, sausage-shaped, minute 

 sporidia. 



On oak (Berk. 1. c). 



This (sec. Berk.) is the Sphmria /rnucida, Fr., var. rostellata, of 

 Schw. Syn. N. Am. 1515, in which the asci are 25 /x long. In the 

 specc. on oak, they are rather larger. 



ORYPTOSPHilRIA, Nitschke. 



Pyt. Germ. p. 159 (as a subgenus). 



Stroma effused or wanting, not limited by any black, circumscrib- 

 ing line. Perithecia buried in the unaltered substance of the bark, 

 irregularly scattered, not penetrating to the wood. Ostiola erumpent, 

 but not exserted. Asci 8-spored, aparaphysate. Sporidia allantoid, 



hyaline. 



Nitschke included also species with polysporous asci (Cryptovalsa).

Stroma cortical, effused in patches of greater or less extent (^-2 

 inches), sunk in the bark, which is blackened down to the wood, and 

 mostly swollen and raised on the surface in the form of a broad, flat 

 blister, the margin gradually slanting off, or abrupt, sometimes rising 

 as much as 1 mm. above the surrounding bark, and mostly somewhat
