Apothecia scattered, solitary, punctiform, subsessile, when 

 dry visible to the unaided eye only as dots, waxy-cartilaginous, 

 the color to the unaided eye similar to that of the dried leaves on 

 which they occur, when magnified pale-yellow to pale-orange; 

 hymenium plane to slightly concave; asci clavate, reaching a 

 length of 60-70 ju and a diameter of 8-10 n; spores straight, or 

 slightly curved, clavate, the narrow end downward, 3.5-4 X 14- 

 16 ju; paraphyses simple, slightly enlarged above, reaching a 

 diameter of 2.5-3.5 /x. 



On fallen leaves of Fagus grandifolia. 



Type locality: Adirondack Mountains, New York. 



Distribution: New York; also reported from Michigan on

Apothecia rather numerous on localized areas of the leaf 

 surface, sometimes in groups of five to fifteen with occasional 

 scattered ones, very small, appearing sessile but with a short, 

 obscure stem, less than 1 mm. in diameter, when fresh bright 

 lemon-yellow, not contracting or changing color much on drying; 

 stem very short and scarcely noticeable; hymenium convex when 

 fresh and bright-yellow, on drying becoming plane and remaining 

 yellow to pale-orange; asci short, clavate, reaching a length of 

 38 to 55 jj. and a diameter of 6-8 ju, 8-spored; spores 2-seriate, or 

 irregularly crowded, slightly irregular in outline, simple, 2-3 X 

 12-18 ju, often containing several small oil-drops; paraphyses 

 rather stout, scarcely enlarged above, occasionally branched, 

 3-3.5 ;u in diameter at their apices.
