Stroma at first clavate, soon expanded and discoid above, brown 

 outside, the inner substance and disk white. Stipe subelongated 

 (reaching 1-2 cm.), mostly penetrating the matrix and hidden. Disk 

 generally 2-5 mm. diam., exceptionally 10-15 mm., grayish-white, 

 pulverulent at first. Perithecia globose, black within and without, 

 about \ mm. diam., their rather large, black, papilliform ostiola dot- 

 ting the white disk. Asci cylindrical, 120-150x15-17 fi (p. sp. 

 80 90 p. long), with abundant, but imperfectly developed paraphyses. 

 Sporidia uniseriate, elliptical, subinequilateral, soon opake, surrounded 

 at first by a hyaline, gelatinous coat, 15-20 x 10-12 /i (10-26 x 10- 

 14 /*, Winter). 



On horse dung, Kansas (Cragin). 



The measurements of asci and sporidia are from the Kansas 

 specimens.

Stroma erect, simple (or sometimes branched), with a distinct, 

 smooth, light brown stipe 2-3 cm. high, 2-3 mm. thick at the clavate- 

 swollen base, enlarged above into a dull white, suborbicular, 2-3 mm. 

 disk, which is at first concave, then plane, and pierced by the slightly 

 prominent, black, papilliform ostiola. Perithecia ovate, sunk in the 

 stroma. Asci cylindrical, short-stipitate, 8-spored, 100-120 x 18-20 /z, 

 with long, filiform pseudoparaphyses. Sporidia mostly uniseriate. 

 elliptical, 28-30x16 //, with a thick hyaline gelatinous coat at first, 

 finally nearly black. 



On horse dung. Alabama (Peters), Texas (Wright). 



Readily distinguished from P. punctata by its long, clavate- 

 swollen stipe.
