Apothecia scattered or gregarious, at first turbinate, becoming 

 expanded and reaching a diameter of about 1 mm., grayish; 

 hymenium plane or nearly so, of the same color as the outside of 

 the apothecium, roughened by the large protruding asci; asci 

 broad-clavate, attenuated below into a stem-like base, reaching 

 a length of 250 ;u and a diameter of 40 ix; spores 2-seriate or 

 irregularly disposed, ellipsoid, often with a small knob or apiculus 

 at one or both ends, hyaline, granular within and often sur- 

 rounded by an accumulation of granules which give to the out- 

 side of the spore a granular appearance but apparently with no 

 true sculpturing, 14-16 X 30-36 /i; paraphyses slender, scarcely 

 enlarged above, hyaline or subhyaline. 



On cow dung.
