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.
Menegazzia caviisidia (ツブクダチイ) is a rare species of foliose lichen found in Japan. It was formally described as a new species in 2004 by Jarle Bjerke and Peter James. Characteristics of the lichen include its numerous spherical to finger-like (dactyliform) to narrowly obovate, hollow isidia, and small conical perforations in the thallus. It contains thamnolic acid as the major lichen product in the medulla.
Menegazzia confusa is a species of foliose lichen found in Australia. It was formally described as a new species in 1987 by lichenologist Peter James. The type specimen was collected by Gintaras Kantvilas near Lake Leake Road in Tasmania, where it was found growing on the bark of Exocarpos cupressiformis in a sclerophyll forest. It also occurs in Victoria. The lichen is quite similar to Menegazzia platytrema, but typically has more crowded apothecia, and lobes that are shorter and more congested. Menegazzia confusa contains caperatic acid as its primary lichen product, whereas M. platytrema contains stictic acid and related compounds.
Menegazzia dispora is a species of corticolous (bark-dwelling), foliose lichen from South America. It was first formally described in an 1876 publication of James Crombie, with authorship attributed to Finnish lichenologist William Nylander. The type specimen was collected as part of a scientific expedition to South America conducted on the Royal Navy survey vessel HMS Nassau. Rolf Santesson transferred it to the genus Menegazzia in 1942.
Menegazzia foraminulosa is a species of corticolous (bark-dwelling), foliose lichen that is endemic to New Zealand. The lichen was first formally described as a new species in 1876 by August von Krempelhuber. Friedrich Bitter transferred it to the genus Menegazzia in 1901. The species contains several lichen products, including depsides, depsidones, as well as fatty acids and pigments.
Menegazzia fumarprotocetrarica is a species of corticolous (bark-dwelling), foliose lichen found in South America. It was formally described as a new species in 1996 by Mónica Adler and Susana Calvelo. The type specimen was collected by the second author from Bariloche. The species epithet refers to the presence of protocetraric acid, a lichen product that is rare in the genus Menegazzia. The lichen grows on the hard bark of Nothofagus alpina, N. dombeyi, and Araucaria araucana.
Menegazzia globulifera is a species of foliose lichen found in New Zealand, Australia, and southern South America. It was formally described as a species new to science in 1942 by Swedish lichenologist Rolf Santesson. The type specimen was collected north of Lago Fagnano. The lichen is typically encountered as an epiphyte, but occasionally it has been recorded growing on rocks. Menegazzia globulifera contains usnic acid and lecanoric acid as major lichen products.
Menegazzia hypernota is a species of foliose lichen found in Australasia. It was formally described as a new species in 2004 by Jarle Bjerke from specimens collected in New Zealand. The lichen contains fumarprotocetraric acid as the major lichen product in the medulla. Menegazzia hypernota was reported from Tasmania in 2019.
Menegazzia kawesqarica is a species of foliose lichen found in southern South America. It was formally described as a new species in 2001 by lichenologists Jarle Bjerke and Arve Elvebakk. The type specimen was collected by the second author in a depression of a volcanic rock outcrop in Morro Chico. The lichen contains atranorin, stictic acid, cryptostictic acid, menegazziaic acid, and constictic acid as lichen products.
Menegazzia minuta is a rare species of foliose lichen that is endemic to Tasmania, Australia. It was scientifically described as a new species in 1987 by lichenologists Peter James and Gintaras Kantvilas. The type specimen was collected by the second author south of Arthur River, where the lichen was found in a rainforest growing on twigs of leatherwood. The species epithet minuta refers to the small size of its thallus. Menegazzia minuta contains protolichesterinic acid, a lichen product that helps to distinguish it from the similar species Menegazzia eperforata, which instead contains stictic acid and related compounds. In a 2012 publication, Kantvilas called M. minuta "one of Tasmania's rarest lichens", characterised by a "glossy olive-brown thallus of minute, spidery lobes, densely beset with lobule-like isidia".
Menegazzia pedicellata is a species of lichen found in Japan that was described as new to science in 2004 by Norwegian lichenologist Jarle Bjerke. It contains caperatic acid.
Menegazzia pertransita is a species of foliose lichen in the large lichen family Parmeliaceae. It is found in New Zealand, Australia, and South America. The lichen was first formally described by Scottish physician and bryologist James Stirton in 1877 as Parmelia pertransita. Swedish lichenologist Rolf Santesson transferred it to the genus Menegazzia in 1942.
Menegazzia sanguinascens is a species of foliose lichen found in southern South America. 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.
Menegazzia terebrata is a species of foliose lichen found scattered across many continents, including North America, South America, Europe, Africa, and Asia.
Menegazzia abscondita is a species of foliose lichen in the family Parmeliaceae. Found in Australasia, the species was described as new to science by Australian lichenologist Gintaras Kantvilas in 2012. The type specimen was collected along Gordon River Road in Tasmania at an altitude of 340 m (1,120 ft). Here it was found growing on satinwood at the edge of a wet eucalypt forest. The specific epithet abscondita means "hidden", and refers to "the effort required to collect sufficient material upon which to base its description".
Menegazzia petraea is a rare species of foliose lichen in the family Parmeliaceae. Found in Australia, the species was described as new to science by Australian lichenologist Gintaras Kantvilas in 2012. The type specimen was collected at the summit of Gog Range, Tasmania at an altitude of 720 m (2,360 ft). Here it was found growing on conglomerate boulders in scrubby heath. The specific epithet petraea not only refers to its saxicolous habitat, but also indirectly hints at the first name of English botanist and lichenologist Peter Wilfred James, who, according to Kantvilas, "has made significant contributions to the study of Menegazzia and first noted the unusual chemical composition of this species".
Menegazzia subtestacea is a species of foliose lichen in the family Parmeliaceae. It is found in Tasmania (Australia), where it grows at high elevations on the twigs and young branches of alpine shrubs.
Menegazzia tarkinea is a rare species of foliose lichen in the family Parmeliaceae. It occurs in North West Tasmania (Australia).
Menegazzia bjerkeana is a rare species of foliose lichen in the family Parmeliaceae. It occurs in rainforests along the New South Wales-Queensland border, where it grows on the bark of southern beech trees.
Menegazzia gallowayi is a species of lichen in the family Parmeliaceae. Found in New Zealand, it was formally described as a new species in 2012 by Australian lichenologist Gintaras Kantvilas. The type specimen was collected near the Craigieburn stream at an altitude of 1,050 m (3,440 ft). Here it was found growing on a young mountain beech. The specific epithet honours New Zealand lichenologist David John Galloway. According to Kantvilas, his work Flora of New Zealand Lichens has "greatly advanced knowledge of the lichens of the Southern Hemisphere".
