Celeb. Leighton 1. c. sine dubio specimen nondum plane 
evolutum ante oculos habuit, quod ieon sporæ ab eo 1. c. data 
satis demonstrat. Noster lichen ab illo Leightonii differt thailo 
fuscescente et margine non aquose brunneo sed tenui limitato; 
sporarum forma omnino eadem ac in specimine Leightonii. 
Tab. nostra, fig. 4, sporæ tres.
