Stroma widely effused, surrounding the branch or stem, or occu- 

 pying numerous small spots, or areas, mostly covered by the bark, but 

 sometimes exposed, surface of the wood blackened with a circumscrib- 

 ing line penetrating deeply. Perithecia loosely scattered or here and 

 there crowded in subvalsiform groups, small, globose, partly or wholly 

 sunk in the wood. Ostiola cylindrical, erumpent, spine-like or, by the 

 pressure of the enclosing bark, deformed and bent. Asci cylindiical 

 or subclavate, sessile, 8-spored, 50-60 x 7-9 fi. Sporidia biseriate or 

 oblique, narrow-fusoid, 12-15 x 3 fi, scarcely constricted.

Perithecia scattered irregularly or subcircinate, 2-8 together 

 buried in the surface of the wood, about \ mm. diam., globose, abruptly 

 contracted above, their slender necks converging and emerging from 

 the bark in a little fascicle of short {\-\ mm.), black ostiola, with 

 abruptly swollen tips, the bark being raised into slight pustules around 

 them. Stroma varialjle in extent, 1-3 or more centimeters long and 

 i-1 cm. wide, consisting of the scarcely altered substance of the wood, 

 and suiTOunded by a black line penetrating deeply. Asci p. sp.
