Of this lichen Dr. Nylander remarks [I. c.) : — " Vix est nisi 

 varietas E. fraxinece^ thallo magis contracto et subfastigiato- 

 diviso vel laciniis subfastigiatis. Sporce magis typice curvulfB 

 quam in B. calieari^ quaj certe arctissime affinis, et forsan hge 

 amba3 alifeque cohabitantes sgepe hybridas proferant formas 

 interccdentes, qiiarmii determinatio aliquando nonnihil in- 

 certa maneat ; typus tamcn ssepius notis datis sat facile est 

 agnoscendus."
