Pleurosticta acetabulum is a species of foliose lichen in the family Parmeliaceae. It is common and widespread throughout Europe, [2] where it grows on tree bark. It has also been recorded in Algeria. [3]
Pleurosticta acetabulum is the type species of Pleurosticta – a genus circumscribed by mycologist Franz Petrak in 1931. Petrak's original type species was named Pleurosticta lichenicola, but this is now known as a synonym of P. acetabulum. [4] [5] It was originally described as Lichen acetabulum by Belgian physician and botanist Noël Martin Joseph Necker in 1768. It has been shuffled to several genera in its taxonomic history, acquiring many synonyms. For example, Georg Franz Hoffmann placed it the genus Lobaria in 1796, while Duby considered it a Parmelia in 1830. In more recent history, Maurice Choisy placed it in Parmotrema , while Ted Esslinger moved it to Melanelia . [1] Most recently, John Elix and H. Thorsten Lumbsch transferred it to Pleurosticta when they resurrected that genus in 1988. [6]
The lichen contains several secondary chemicals, including atranorin, salazinic, norstictic, protocetraric, and evernic acids. [7]
Lichenicolous fungi that have been recorded growing on Pleurosticta acetabulum include Abrothallus acetabuli , [8] Lichenoconium erodens , [9] and Stigmidium acetabuli . [10]
Pleurosticta acetabulum has been used for research investigating its tolerance to extreme environmental conditions, such as those that might be found on planet Mars. It was shown that following exposure to complete dehydration, extremely low temperature (-196°C/77K), and oxygen depletion, the lichen was able to recover and its ability to produce a high yield of hydrogen was unchanged. This suggests that it might have use in astrobiological applications as a hydrogen producer in bioregenerative life support system for extraterrestrial environments. [11]
Cladia is a genus of lichenized fungi in the family Cladoniaceae. Cladia species have a crustose primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, Cladia aggregata, is widely distributed, occurring from South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere.
Allocetraria is a genus of lichenized fungi in the family Parmeliaceae. It consists of 12 species, with a center of distribution in China.
Hypogymnia is a genus of foliose lichens in the family Parmeliaceae. They are commonly known as tube lichens, bone lichens, or pillow lichens. Most species lack rhizines that are otherwise common in members of the Parmeliaceae, and have swollen lobes that are usually hollow. The lichens usually grow on the bark and wood of coniferous trees.
Tuckermannopsis is a genus of foliose lichens in the family Parmeliaceae.
Melanohalea is a genus of foliose lichens in the family Parmeliaceae. It contains 30 mostly Northern Hemisphere species that grow on bark or on wood. The genus is characterized by the presence of pseudocyphellae, usually on warts or on the tips of isidia, a non-pored epicortex, and a medulla containing depsidones or lacking secondary compounds. Melanohalea was circumscribed in 2004 as a segregate of the morphologically similar genus Melanelia.
Pleurosticta is a genus of lichen belonging to the family Parmeliaceae. It has two species. The genus was circumscribed by mycologist Franz Petrak in 1931, with Pleurosticta lichenicola assigned as the type species. This is now known as a synonym of P. acetabulum.
Punctelia is a genus of foliose lichens belonging to the large family Parmeliaceae. The genus, which contains about 50 species, was segregated from genus Parmelia in 1982. Characteristics that define Punctelia include the presence of hook-like to thread-like conidia, simple rhizines, and point-like pseudocyphellae. It is this last feature that is alluded to in the vernacular names speckled shield lichens or speckleback lichens.
Xanthoparmelia is a genus of foliose lichen in the family Parmeliaceae. Xanthoparmelia is synonymous with Almbornia, Neofuscelia, Chondropsis, Namakwa, Paraparmelia, and Xanthomaculina. This genus of lichen is commonly found in the United States, as well as Australia, New Zealand and Ecuador.
Everniopsis is a fungal genus in the family Parmeliaceae. It consists of a single species, the bark-dwelling lichen Everniopsis trulla, which occurs in Africa and South America.
Nesolechia is a genus of parasitic fungi in the family Parmeliaceae. All three species in the genus grow on lichens. Nesolechia probably evolved from a lichen ancestor, as it is closely related to many lichenized species of fungi.
Phacopsis is a genus of lichenicolous (lichen-dwelling) fungi. They are parasites of members of the large lichen family Parmeliaceae, of which they are also a member. Originally proposed by Edmond Tulasne in 1852 to contain 3 species, Phacopsis now contains 10 species, although historically, 33 taxa have been described in the genus. Many of the species are poorly known, some of them having been documented only from the type specimen.
Coelopogon is a genus of lichen-forming fungi in the family Parmeliaceae. The genus contains two species found in southern South America and South Africa.
John Alan (Jack) Elix emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology.
Helge Thorsten Lumbsch is a German-born lichenologist living in the United States. His research interests include the phylogeny, taxonomy, and phylogeography of lichen-forming fungi; lichen diversity; lichen chemistry and chemotaxonomy. He is the Associate Curator and Head of Cryptogams and Chair of the Department of Botany at the Field Museum of Natural History.
Pleurosticta koflerae is a species of foliose lichen in the family Parmeliaceae. It is a member of the group of species informally known as the "brown Parmeliae". The lichen was first formally described as Parmelia koflerae by lichenologists Georges Clauzade and Josef Poelt in 1961. Theodore Esslinger transferred it to the genus Melanelia in 1978 when he reorganized the classification of the brown Parmeliae, a continuation of his research on the group published the year before. It was finally transferred to the newly resurrected genus Pleurosticta in 1988 by H. Thorsten Lumbsch and John A. Elix.
Xanthoparmelia loxodes is a species of foliose lichen in the family Parmeliaceae. It was first formally described by Finnish botanist William Nylander in 1872, as Parmelia loxodes. In 1978, Ted Esslinger created the genus Neofuscelia, which contained species previously classified in Parmelia subgenus Neofusca; Neofuscelia loxodes was one of many species transferred here. In a 2004 molecular phylogenetic study published by Oscar Blanco, Ana Crespo, John A. Elix, David L. Hawksworth and H. Thorsten Lumbsch, they showed that Neofuscelia did not form a clade distinct from Xanthoparmelia, and they reduced it to synonymy under Xanthoparmelia.
Punctelia stictica is a species of foliose lichen in the family Parmeliaceae. It is widely distributed lichen, recorded in Africa, Europe, North America, South America, and Greenland. It is typically found growing on rocks.
Raesaenenia is a fungal genus in the large family Parmeliaceae. It is a monotypic genus, containing the single lichenicolous fungus Raesaenenia huuskonenii, which parasitises lichens of genus Bryoria in the Northern Hemisphere.
Xanthoparmelia salazinica is a species of lichen in the family Parmeliaceae. Found in South Africa, it was described as a new species in 1989 by American lichenologist Mason Hale. He classified it in Karoowia, a genus that has since been placed in synonymy with Xanthoparmelia following molecular phylogenetic analysis published in 2010.
Phacopsis thallicola is a species of lichenicolous (lichen-dwelling) fungus in the family Parmeliaceae. It was first formally described as a new species in 1852 by Italian botanist Abramo Bartolommeo Massalongo, as Lecidea thallicola. The type specimen, collected from the province of Treviso in Italy, was growing on the foliose lichen Parmelia caperata. Dagmar Triebel and Gerhard Walter Rambold transferred the taxon to the genus Phacopsis in 1988. The known generic hosts of Phacopsis thallicola are all in the Parmeliaceae: Parmotrema, Cetrelia, Flavopunctelia, and Hypotrachyna.
