iSphaeria." 



Covered ; perithecia ovate, delicate, springing from scattered,

Scarcely visible unless the leaf is held up to the light. Perithecia delicate, 

 ovate, with a very short neck and round aperture, like a little India rubber 

 bottle, springing from threads which are mostly branched at right angles. 

 Asci very delicate, clavate. Sporidia ("05 in.) "127 m.m., linear-fusiform, 

 with several endochromes, varying much in size. This species is very liable 

 to be overlooked unless the leaves chance to be saturated with moisture. —
