89 
Spores completely covered by sec- 
9. P. longicaudata. 
10. P. multicaudata. 
11. P. dakotensis. 
Perithecia naked above the substratum, 
ondary appendages. 
Primary spore-appendages absent. Spores 2-seriate. 
Asci more than 8-spored. 
Perithecia hairy above the substratum. 
Hairs short, forming tufts of irregular cells. 
Hairs long and single. 
Hairs straight and more or less clustered. 
Hairs flexuous and similar to the mycelium. 
Perithecia naked above the substratum. Secondary spore-appendages easily 
distinguishable at maturity. \14. P. pleiosbora - --^

12. P. curvicolla. 
13. P. collapsa. 
Perithecia scattered, half-sunken, globose to pyriform-conic with a 
long, cylindric, curved or twisted, black beak, 845-935x435-630 mic., 
slightly olivaceous when young, but becoming dark-brown to black, 
transparent when young, showing spores in the asci, becoming opaque, 
membranous to slightly coriaceous at maturity, covered uniformly on all 
exposed portions by simple, straight, septate, smooth, brown, hyaline- 
tipped, fugacious hairs of 2-4-cells, 25-40x3-4 mic; paraphyses simple, 
filiform, tapering upward, numerous, longer than the asci and mixed with 
them, septate, evanescent; asci cylindric, broadly rounded above and 
contracted below into a long, slender, crooked stipe 342x37.5 mic., 
4-spored, evanescent; spores 1-seriate, ranging from hyaline when young 
through pale-yellow, olivaceous to dark-brown and opaque, long ellipsoid 
to ovoid, acutely rounded below, 30-60x22-28 mic., with the primary 
appendage reduced to a minute, hyaline or often slightly colored apiculus 
at the lower end of the spore and with secondary gelatinous appendages, 
the lower one being very long, attached apically to the spore, inclosing 
the minute apiculus, easily resolved into two closely united portions 
which appear to lose their individuality distally and which at first are 
thrown into convolutions at the base resembling segments of the tape¬ 
worm, these disappearing when it elongates, the upper appendage being 
slightly smaller than the lower, eccentrically attached and also having 
convolutions at first. 
Habitat: On dung of horses, cows, rabbits, burros, dogs, and sheep. 
Distribution: Rhode Island to Ohio, South Dakota, Arizona, and 
Alabama. 
Illustrations: PI. V, f. 4-8; Mem. Torrey Club 11: pi. 6, f. 1-3. 
Type Locality: New York City. 
Distinctive Characters: Large spores, minute apiculum, and long 
convoluted appendages at maturing time. 
Notes: From the material at hand, the author was able to measure only one ascus accurately 
and a few perithecia, in most of which the asci had disappeared. 
Plants cultivated in the laboratory, June 19, 1917, on rabbit dung collected by Wm. A. Stratton, 
at Sardinia, Dec. 29, 1916.
