Menegazzia eperforata is characterised by: the corticolous habit; the lack of perforations; the presence of true isidia that are simple, cylindrical or spathulate and which never burst open into the coarsely granular, torn pustules seen in M. nothofagi. It was first collected in New Zealand in 1926 by G. Einar and Greta Du Rietz, when they discovered it as an epiphyte of Nothofagus truncata in coastal forest at York Bay, Wellington.
