The species is distinguished by the whitish-grey thallus without parietin

Differs from Rinodina peloleuca (Nyl.) Müll.-Arg. in the much smaller 
spores ; like that species it recalls Lecanora cinerea, but is of a more minute 
and regular formation. The chemical reaction (not recorded in Æ, peloleuca) 
is very distinct.
