THE FIMETARIALES OF OHIO

branous, cellular structure being plainly visible, with exposed portions 
more or less covered with bunches of agglutinate, obliquely septate, hya¬ 
line to light-brown, constricted hairs which are more or less prominent 
around the beak, but diminish in size and prominence downward; para- 
physes ventricose, agglutinate, longer than the asci and not much mixed 
with them; asci clavate, contracted above and tapering below into a mod¬ 
erately long, slender, straight or crooked stipe, 175-245x25-32.5 mic., 
8 spored, evanescent; spores 2-seriate, ranging from hyaline when young 
through olivaceous to dark-brown and opaque, ellipsoid to ovoid, 19-23x10- 
15 mic., with a cylindric, straight or curved primary appendage, .5 to .7 
the length of the spore, which as well as the apex of the spore is tipped 
with a long, lash-like, gelatinous, secondary appendage, varying in length 
with the stage of development, the upper being excentrically placed and 
both being made up of 2 closely united filaments which are plainly dis¬ 
tinguishable proximally but which appear to fuse together distally. 
Habitat: On dung of horses, cows, goats, sheep, pigs, and rabbits. 
Distribution: New York to Ohio, Montana, Arizona, and Alabama; 
also in Europe. 
Illustrations: PL VII, f. 1-5; Mem. Torrey Club 11: pi. 7, f. 1-6. 
Type Locality: Europe. 
Distinctive Characters: Agglutinated hairs of perithecia and 
2-seriate arrangement of spores. 
Note: Plants cultivated in the laboratory, April 2, 1917, on horse dung collected by Chas. R. 
Stevenson, at Stout, Jan. 1, 1917.

Perithecia scattered, or sometimes in rows of 3 to 5, superficial or 
with base slightly sunken, ovoid to ovoid-conic with a short, flat, 
papilliform, black ostiolum, 670-830x510-670 mic., dark-brown to black, 
membranous to coriaceous, with thick, pale-brown, somewhat transparent 
wall, cell-walls showing as white lines over the surface which is covered 
sparingly with simple, straight, septate, smooth, pale-brown, hyaline- 
tipped, persistent hairs 25-130x3-4 mic., composed of 2-8 cells, apical 
one hyaline; rhizoids simple or branched, almost straight, 3-5 mic. thick, 
sparingly septate, smooth, pale-brown; paraphyses usually simple, filiform, 
numerous, about equaling the asci and mixed with them, septate, 
shriveling up and disappearing at maturity of the spores; asci clavate, 
contracted and rounded above, and tapering below into a short, usually 
crooked, stipe-like base, 200-300x30-40 mic., 8-spored, rather persistent; 
spores 2-seriate, 4 and 4 or 5 and 3, ranging from hyaline when young 
through olivaceous-brown to dark-brown and opaque, ellipsoid, somewhat
