 the lower part sunk in the wood, necks convergent and orumpent in a 

 compact fascicle of stout but short, cylindrical ostiola, which perforate 

 the epidermis, but do not rise much above it, their tips rounded or 

 obtusely conical, and finally with a large irregular opening. Stroma 

 variable, orbicular, irregular in outline, often widely confluent and con- 

 tinuous for several indies, faintly circumscribed. Asci oblong-clavate.

On a section exposing the perithecia they seem to lie almost 

 evenly scattered. Sec. Cooke, the sporidia are 1-5-septate, 40x4 //. 

 but we can only find them as stated above.

Perithecia sunk in the wood, J-J mm. diam., in siibcircinate 

 groups of 6-10, circumscribed by a black line which penetrates deeply 

 into the wood and encloses a space considerably larger than that occu- 

 pied by the perithecia. Ostiola erumpent through the ruptured epi- 

 dermis (which is also slightly raised), stout, short-cylinclrical, obtuse, 

 perforated, enveloped in a sulphur-yellow, grurnous substance which 

 finally disappears. The wood of the stroma within the circumscribing 

 line is also tinged sulphur-yellow. Asci oblong-fusoid, p. sp. about 

 60x8-10 //. Sporidia biseriate, oblong or subelliptical, subobtuse, 

 12-15x4 //, uniseptate and constricted.
