Of this lichen Dr. Nylander remarks (I. e.) : — " Vix est nisi varietas R. frax- 

 inece thallo magis contxacto et subfastigiato-diviso vel laciniis Bubfastigiatis. 

 Sporae magis typice curvuhe quam in R. calicari quae certe arctissime afEni et f or- 

 san hoe ambae afiaeque cohabitantes saepe hybridas proferant formas intercedentes 

 quarum determinatio aliquando nonnihil incerta maneat ; typus tamen ssepius 

 notis datis sat facile est agnoscendus." 



"Spores .002—17 mm. long, .009—7 mm. broad." (Nyl.)
