Stroma <it 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 2-6 mm. diam., exceptionally 10-15 mm., grayish-white 

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

 about \ ugn. diam., their rather large, black, papilliforni ostiola dot 

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

 80 90 // long), with abundant, but imperfectly developed paraphyses, 

 Sporidia utiiseriate, elliptical, subinequilateral, soon opake, surrounded 

 at first by a hyaline, gelatinous coat, 15-20x10-12/^(10-26x10-

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

 smooth, light brown stipe 2-3 cm. high, 2-3 ram. 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, papilliforni ostiola. Perithecia ovate, sunk in the 

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

 with long, filiform pseudoparapbyses. Sporidia mostly uniseriate, 

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

 finally nearly black.

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

 swollen stipe.
