Distinguished by the areolate and more developed thallus, which is 
often widely expanded. The colour also is of a deeper yellow, though in 
shady places it is at times yellowish-green. The apothecia, which are 
numerous, are also smaller, more convex, with the thalline margin very 
seldom visible, even in young. plants. 
Hab. On rocks and old walls in maritime and upland loculities.— Distr.

Differs in the colour of the thallus, which in our few specimens is 
rather scattered and pale-yellowish. By British authors it has not been 
rightly distinguished from Z. pyracea. ee
