192 FUNGUS-FLORA. 



genera, of the present fungus, as shown in the synonymy. 

 His Fabraea litigiosa is said to be distinguished by the 1- 

 septate spores, and in the ascophores not being crowded on 

 brown spots ; but Kehm, Ascom., 059, quoted by Saccardo 

 under this form, has the ascophores densely crowded on 

 brown patches, whereas in other exsiccati the ascophores are 

 scattered, and the spores continuous.

Gregarious, epiphyllous, sessile, innate, erumpent, orbicular 

 and plane, glabrous, firm, pale reddish-yellow, sometimes

 hyaline, continuous, smooth, straight, narrowly cylindric- 

 oblong, ends obtuse, sometimes very slightly widest at the
