Apothecia gregarious but not usually crowded, at first globose 

 or short-cylindric, soon opening, pale- to bright-orange, rarely 

 exceeding 1—2 mm. in diameter and often less; hymenium 

 becoming convex, similar in color to the outside of the apo-

 reaching a length of 200 ^ and a diameter of 18-20 /x, 8-spored; 

 spores obliquely or irregularly disposed, broad-ellipsoid, hyaline, 

 smooth, containing either one or two large oil-drops which reach 

 a diameter of about 10 m. entire spore 12-14 X 22-25 ju; pa- 

 raphyses straight or very slightly curved, rather stout, about
