 the total length, ellipsoid-obovate, ellipsoid to subcylindric, 

 obtuse, usually compressed or longitudinally furrowed, .5-2 cm. 

 long, 6-12 mm. wide, sharply differentiated from the stem, 

 usually clear vitelline or orange-yellow, rarely of a duller shade; 

 stem terete, yellow, paler than the ascigerous portion, usually 

 prominently squamulose, 1.5-3 cm. high, 2-3 mm. thick; whole 

 ascophore becoming dingy-yellowish or reddish-brown when 

 dry; asci clavate, apex narrowed, pore blue with iodine, reaching 

 a length of 100-140 fx and a diameter of 10-12 fx, 8-spored; 

 spores 2-seriate, hyaline, smooth, cylindric or slightly narrowed 

 toward the obtuse ends, straight or curved, for a long time con- 

 tinuous, then multiguttulate, finally 5-10-septate, 5-6 X 18- 

 38 n (25-35) ; paraphyses filiform, 2-3 ^i thick below, the apices

Ascophores solitary, or more often densely cespitose, clavate, 

 2-6 cm. high, robust; ascigerous portion obovate, ellipsoid, or 

 oblong, rounded above, more or less compressed and longitudi- 

 nally furrowed, about one-third to one-half the total length of
