Thallus foliaceous or sometimes fruticulose, usually stellato- 
orbicular; gonidial layer consisting of true gonidia, Apothecia 
lecanorine ; spores 8nx, subellipsoid or oblong, variously bilocular, 
or 1-septate, rarely quadrilocular, brown or colourless; paraphyses 
discrete. Spermogones innate; sterigmata usually pluri-articulate ; 
spermatia cylindrical or oblongo-cylindrical, occasionally obsoletcly 
incrassate at either apex, very rarely acicular. 
Consists of a single genus, formerly included under Parmelie?, but 
recently separated by Nylander as a distinct tribe. From the less deve- 
loped thallus and the type of the apothecia it occupies an inferior place 
in the Series,
