76 NORTH AMERICAN FLORA {VoLUME 3 
Perithecia usually more or less sunken, but often quite superficial, scattered or aggre- 
gate in a dense growth of brown or olivaceous mycelium which covers the perithecium up 
to the black, bare, curved or straight, cylindric beak, pyriform, thin, membranaceous, 
black above but greenish below, especially in the sunken portions which are so transparent 
that the asci and spores can be quite distinctly seen, 400-525 X 675-825 4; asci 8-spored, 
clavate, contracted and rounded above, and tapering below into a medium-sized pedicel, 
very evanescent, 40-55 x 180-2104; paraphyses ventricose, very evanescent, longer than 
the asci; spores 2-seriate, ellipsoid to ovoid, rounded above and below, but more narrowly 
so above, ranging from hyaline when young through olivaceous to dark-brown and opaque, 
18-22 X 28-35 #, spore terminated below by a cylindric primary appendage as long as the 
spore or slightly longer, which is tipped with 3 or 4 long, gelatinous appendages similar 
in all respects to those found at the apex of the spore.

Perithecia gregarious, ovoid, conic, 0.65 mm. high and 0.5 mm. broad, black, tubercular- 
roughened, the tubercles seriate above so as to cause the conic beak to appear striate, the 
tubercles at first capped with a few light-colored granules, like grains of white sugar, 
which at length disappear ; asci linear-lanceolate, contracted towards each end and per- 
forate above, 2004 long (or longer, including the filiform base), and 12-15» wide, with 
abundant paraphyses; spores 2-seriate, ellipsoid, brown, 14-16 X 8-104, the upper end 
acute or witha short hyaline appendage 8-12 # long, the lower end prolonged into a yellow- 
ish-hyaline cylindric curved appendage 35-40 X 5 #.
