Menegazzia is a genus of lichenized fungi containing roughly 70 accepted species. The group is sometimes referred to as the tree flutes, honeycombed lichens, or hole-punch lichens. The most obvious morphological feature of the genus is the distinctive perforations spread across the upper side of the thallus. This makes the group easy to recognise, even for those not particularly familiar with lichen identification.

It was first formally described as a new species in 1889 by Swiss botanist Johannes Müller Argoviensis, as a species of Parmelia. The type specimen was collected in the Strait of Magellan in southern Chile. Rolf Santesson transferred the taxon to the genus Menegazzia in 1942. Menegazzia opuntioides has also been recorded from Argentina.

It was first formally described as a new species in 1932 by Finnish lichenologist Veli Räsänen, who included it in genus Parmelia. The type specimen was collected from Agostini Fjord. Rolf Santesson transferred the taxon to Menegazzia in 1942. The species contains atranorin, hypothamnolic acid, and thamnolic acid as lichen products.
