84 NORTH AMERICAN SORDARIACEAE 
evanescent : paraphyses ventricose, agglutinated, abundant, longer 
than the asci and not mixed with t 
Spores obliquely uniseriate, ellipsoid, rounded at both ends, 
18-21 0× 26-35 ,م‎ ranging from hyaline when young through 
olivaceous to dark brown and opaque; primary appendage en- 
tirely absent ; secondary appendage attached to each end of the 
spore, long, gelatinous, evanescent, and composed of two closely 
united filaments, which appear to fuse distally ; these in turn are 
striated longitudinally, making them "i as though they were 
formed of still smaller subdivisions. (P. 8. f. 6-8.) 
Distinctive characters: Hairy ee and absence of 
primary appendages. 
Cultivated specimens: On cow dung, Rooks Co., Kan., July 
1899 (Bartholomew) و‎ horse and cow dung, Austin, Texas, Jan. 
1900 (Long); horse and cow dung, Tucson, Ariz., Jan. 1900 
(Tyler) ; cow dung, Bookings, S. D., Nov. 1899 (Carter). 
The Tucson specimens had perfectly smooth perithecia from 
the beginning as far as could be seen, but the substratum was very 
wet. One may often find in this species 4-8-spored. asci. This 
variation is clearly due to the abortion of four of the spores, 
and not toa failure of the nuclei to divide the third time ; for 
while four spores are in the olive-green stage four other abor- 
tive hyaline ones may usually be found. Later in development 
these disappear entirely when there occurs a 4-spored 
ascus differing from the normal in no other respect than 
that of size.
