This species is closely allied to tlie preceding, but is distinguished by 

 the smaller and constantly naked, somewhat scattered apothecia, and by 

 its being entirely parasitic.

Thallus vertical, fruticuloso-divided or ramulose, subgloboso- 

 incrassate at the apices, within entirely filamentose. Apothecia 

 terminal, innate, at first closed, at length with the thalline receptacle 

 irregularly lacero-dehiscent ; sporal mass copious, black : spores 8n9e, 

 in evanescent thecae, simple or 1-septate, spherical or ellipsoid, 

 blackish or brown. Spermogones terminal, black or pale. 



This is closely allied to the preceding tribe. Their thalli are no duubt 

 very different in form and texture; but the fully developed fructification 

 of the Sjyhcerophorei is similar to that of the Caliciei.
