On cow dung, New York State (Peck), Iowa (Holway). 



In the Iowa specimens, the perithocia are ovate-conical, about 

 1 mm. high and | mm. broad, the horn-like tufts of hair around the 

 vertex numerous, short and erect. Asci (p. sp.) 115-140x15-20//. 

 Sporidia elliptical, 22-27 x 12-14 /i, mostly biseriate above.

Perithecia superficial, coriaceo-membranaceous, ovate or' ovate- 

 conical, |-f mm. high and about | as much broad, sparingly clothed 

 with straight, spreading, brown, septate hairs 50-100 [i long. Ostio- 

 lum broad-papilliform, bare and black. Asci ventricose-clavate, atten- 

 uated above, paraphysate, 140-160 X 25-35 fi. Sporidia crowded-bi- 

 seriate, cylindrical, hyaline and nucleate at first, with a slender appen- 

 dage at each end about as long as the sporidium, finally acutely ellip- 

 tical and Opake, with the terminal appendage about 20 x 5 /i, rounded 

 and obtuse at the end, and the lower one of about the same length or 

 a trifle narrower, with a transverse septum about 1 2 /i from the end of 

 the sporidium. Each of these appendages, at a certain stage of growth, 

 has a slender, hyaline, thread-like prolongation several times longer 

 than the thicker, basal appendage, but this slender prolongation soon 

 disappears. 



On rabbit's dung. New Jersey, and New York. 



Differs from S. curvula, de Bary, in its sparsely scattered, not 

 fasciculate hairs, and the diiferent character of the appendages of the 

 sporidia, which resemble more those of P. Jimiseda, Ces. & De Not, 

 from which our species may be distinguished by its smaller, and less 

 densely hairy perithecia.

Perithecia scattered or collected in small groups, erumpent-super- 

 ficial, ovate-globose, attenuated above into a moi'e or less distinct neck, 

 dark brown, thickly clothed all over with dark brown, short, septate 

 hairs, 1-1 1 mm. high. Asci cylindrical, with a long, stipe-like base, 

 somewhat attenuated above, about \ mm. long, p. sp. 350-400 x 45-

 was not given to the public until after Sphceria amphicornis was published in the Torr Bull,
