78 NORTH AMERICAN FLORA [VoLumE 3 
broadly rounded above and contracted below into a short slender stipe, 26-32 180-240 pz, 
evanescent ; paraphyses ventricose, agglutinate, abundant, longer than the asci and not 
mixed with them; spores obliquely 1-seriate, ellipsoid, rounded at both ends, 18-21 
X 26-35 #, ranging from hyaline when young through olivaceous to dark-brown and 
opaque; primary appendage entirely absent ; secondary appendages attached to each end 
of the spore, long, gelatinous, evanescent, each composed of 2 closely united filaments, 
which appear to fuse distally, and are striate longitudinally, making them appear as 
though formed of still smaller subdivisions.
