An observation on this species represents it as "only a 

 diseased state of P. glaucoma.^'' But the idea of disease 

 is a mistate. It has a slight resemblance to some forms 

 of Lecanora glaucoma, in the angular or flexuose appear- 

 ance of the apothecia, but in the colour and reaction of 

 the thallus it is sufficiently distinct from it, as a species.
