Apothecia gregarious or thickly crowded, seated on a rather 

 dense growth of yellowish or whitish mycelium, at first globose, 

 expanding and becoming discoid or subdiscoid, externally golden- 

 yellow, reaching a diameter of 1-2 mm.; hymenium at first 

 concave or plane, becoming strongly convex, at first similar in 

 color to the outside of the apothecium, becoming dotted over 

 with the ends of the protruding asci which appear black on 

 account of the dark-colored spores, entirely black when mature; 

 asci very broad-clavate, gradually narrowed below into a stem, 

 like base, reaching a length of 125 ^ and a diameter of 30 ix, 

 8-spored; spore-mass elongated, reaching a length of 50-70 ji and 

 a diameter of 20-27 p.\ spores ellipsoid, with the ends narrowed, 

 strongly swollen near the center, often subfusoid and slightly 

 unequal-sided, hyaline, becoming violet, later brown, often deli- 

 cately sculptured, 10 X 20-23 /x; spore-sculpturing taking the 

 form of very delicate reticulations; paraphyses slender, branched 

 rather freely, golden-yellow, thickened above. 



On dung of various kinds. 



Type locality: Europe. 



Distribution: New York to Colorado, Bermuda and Porto 

 Rico, probably common throughout North America; also in 

 Europe.
