 Caloplaca stiUicidionan and C. juiigerjiiajuiiac. 



The few gonidia under the hypothecium might indicate a Lecanora. 

 But the habitus is Lecideine or Biatorine. The structure of the apothecia 

 calls to mind Lecidca (Biatora) septentrionalis Th. Fries Scand. p. 475, 

 which, however, has a better developed darker thallus and much larger 

 apothecia (ca. 1 mm.).
