On cow dung, Ne\v York State (Peck), Iowa (llohvay). 



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

 1 mm. high and mm. broad, the horn-like tni'ts of hair around the 

 vertex numerous, short and erect. Asci (p. sp.) 115-140x15-20/7.. 

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

Perithecia superficial, coriaceo-membranaceous, ovate or ovate- 

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

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

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

 uated above, para physate, 140- 160 x 25-35 //. Sporidia crowded-bi- 

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

 dage at ea.ch end about as long as the sporidium, finally acutely ellip- 

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

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



o 



a trifle narrower, with a transverse septum about 1 2 // 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 different character of the appendages of the 

 sporidia, which resemble more those of P. fimiseda, 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 more or less distinct neck, 

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

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

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



*The 28th Report in which Peck's Sphteria eximia was published is dated Jan. 1875, but 

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

 in Sept. 1876.
