the asci, but not mixed with them; spores in several series, ellipsoid, broadly rounded at 
both ends, 13-19 X 26-32 n, ranging from hyaline when young through olivaceous to dark- 
brown and opaque; primary appendage wide, cylindric, shorter than the spore and quite 
Persistent ; secondary appendages terminating the primary and apex of the spore, at first 
long, delicate filaments made up of 2 strands, but at maturity appearing like 2 short, 
irregular projections with very uncertain characters.

Delitschia Auerswaldii Fuckel, Symb. Myc. 241. 1869. 
Perithecia sunken, scattered, with papilliform or long-cylindric, curved or twisted, black 
beak which may be uniformly covered with short, brown, septate hairs or perfectly smooth, 
black and bare, 400-700 in diameter, subglobose to pyriform, thin, membranaceous,
