This plant grows mixed with young states of Lecanora Parella, from which it is with difficulty distinguished, it forms large pure white or pinkish patches, sometimes several inches in breadth, very convex, and often raised above the soil ; the apothecia are hemispherical, with a broad depression, in the centre of which again is often a co- nical mamilla ; there appear to be no spores in the apothecia, and the plant may be merely a rudimentary form of some more highly organized lichen. It is also abundant at Cape Horn and in the Falkland Islands.
