 Internal cavities have walls which are most often white, but in some species they can be pigmented or blackened.Rounded apothecia are produced along the lamina of most of the known "Menegazzia" species, while the others are thought to be entirely asexual (like "M. nothofagi" and "M. globulifera").In the taxa that do produce apothecia, they are always lecanorine, and often cupuliform.
