(Plate 6.) 



Apothecia scattered or closely crowded, sessile, at first 

 globose and appearing closed or nearly so, white or whitish, 

 gradually opening, becoming cup-shaped with the smooth margin 

 inrolled, finally becoming subscutellate, externally pruinose from 

 the projecting tips of thin-walled, hair-like hyphal branches 

 which finally become discolored and brownish, reaching a di-

 first greenish-yellow, roughened by the protruding asci and 

 becoming nearly black at maturity on account of the dark- 

 colored spores; asci cylindric to clavate, reaching a length of 

 200-300 M and a diameter of 18-25 /x, 8-spored; spores becoming 

 irregularly 2-seriate, ellipsoid, at first hyaline, then pale-lilac, 

 finally rose-purple or violet, fading to brown in aged specimens, 

 smooth, becoming sculptured, 12-14 X 20-25 m, germinating by 

 one germ-pore; spore-sculpturing consisting of one faint line 

 extending from one end of the spore to the other or obliquely 

 across its surface; paraphyses filiform, slightly enlarged above, 

 septate, reaching a diameter of 5-7 m at their apices, filled with 

 a greenish granular content.
