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-

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

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

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