Obs. 1. Lecidea arthoniza Nyl., Lich. Scand. (1861) p. 219, partim 

 ad genus Naeviae pertinet {Arthonia intertexta rJ. pauperrima S. Almqu.

 ascos breviores, sporis ovoideo-oblongis biseptatis instructos (sine 

 paraphysibus visibilibus Naeviae), et alios, sporas simplices ellipsoideas 

 normales L. goniophilae foventes, continens, ut jam indicavit Th. Fr.

 nunc denuo microscopic examinavi.
