THE FIMETARIALES OF OHIO 
93 
spores and asci being visible through the wall, thin, membranous, with a 
few bunches of straight, light brown, sparingly septate hairs, about 
75x2-3 mic., on the beak; paraphyses simple, ventricose, numerous, longer 
than the asci and not mixed with them, septate, evanescent; asci clavate, 
rounded and contracted above, and narrowed below into a short stipe, 
about 325x62.5-87.5 mic. expanded or 262-315x40-57 mic. contracted, 
8-spored, evanescent; spores 2-seriate, ranging from hyaline when young 
through olivaceous to dark-brown and opaque, ovoid to oblong ellipsoid, 
30-55x19-25 mic., with a long, cylindric, usually curved primary 
appendage below and with secondary appendages covering the entire 
surface of the spore. 
Habitat: On cow dung. 
Distribution: Ohio. 
Illustration: PI. IX., f. 5-8. 
Type Locality: Near Georgetown, Ohio. 
Distinctive Characters: Long curved primary appendages and 
secondary appendages covering only the entire surface of the spore proper. 
Note: Plants cultivated in the laboratory, June 27, 1917, on cow dung collected by the author, 
near Georgetown, Sept. 7, 1914.

Mycelium more or less superficial, pale-brown, (dingy white to the 
naked eye) branched, septate, with hyphae 3 mic. in diameter; with hvphae 
3- - mic. in diameter -? perithecia scattered, sunken or nearly superficial, 
pyriform with a more or less elongate, cylindric, black, bare and curved 
beak, 685-1080x465-730 mic., slightly green to brown below and black 
above, somewhat transparent, thin, membranous, covered below with an 
arachnoid mycelium; paraphyses simple, ventricose, tapering upward, 
rather numerous, longer than the asci and not mixed with them, septate, 
agglutinate; asci clavate, broadly rounded above and contracted below into 
a long, slender, crooked stipe, 250-365x35-60 mic., 4 to 8-spored, very 
evanescent; spores 2-seriate to irregular, consisting of an ellipsoid to ovoid 
fertile cell, usually rounded at both ends, but more acutely so distally, at 
each end of a long, spirally arranged hyaline to brown, fugacious filament 
which corresponds to the primary appendage in the other species, with 
terminal fertile cells 19-45x10-23 mic., ranging from hyaline when young 
through olivaceous to dark-brown and opaque and which have secondary 
appendages consisting of usually 4, rather short, tapering, hyaline, 
gelatinous, widespread processes attached to the distal ends of the fertile 
cells and sometimes to both ends. 
Habitat: On dung of horses, cows, goats, sheep, and pigs.
