Allocetraria corrugata is a species of foliose lichen in the family Parmeliaceae. It is found in high-elevation locations in Yunnan, China, where it grows on rocks with mosses.
The lichen was described as a new species in 2015 by Rui-Fang Wang, Xin-Li Wei, and Jiang-Chun Wei. The type specimen was collected from Meili Snow Mountain at an altitude of 4,400 m (14,400 ft). The specific epithet corrugata refers to the corrugated surfaces of the lobes. [1]
In 2017, Divakar and colleagues proposed to synonymize genus Allocetraria (and several other Parmeliaceae genera) with Cetraria , which would result in a name change to Cetraria corrugata. [2] The proposal was rejected by later authorities. [3] [4]
The lichen thallus comprises narrow, slightly inflated lobes measuring 1–4 mm wide and 200–450 μm thick. Its surface colour is green to greenish-yellow, and its has a strongly wrinkled texture. Apothecia are absent, but there are pycnidia that appear as small black dots both immersed in the thallus and elevated on the surface. Allocetraria corrugata contains the secondary chemicals usnic acid, fumarprotocetraric acid, and protocetraric acid. The lichen, known to occur only in Yunnan Province, grows on rocks with mosses. [1]
Allocetraria isidiigera is somewhat similar in appearance, but differs from A. corrugata in its shorter lobes, the presence of isidia, and slightly smaller conidia. [1]
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.
Cetraria is a genus of fruticose, Iceland lichens that associate with green algae as photobionts. Most species are found at high latitudes, occurring on sand or heath. Species have a characteristic "strap-like" form, with spiny lobe edges.
Pseudevernia is a genus of foliose lichens in the family Parmeliaceae. The type species of the genus, Pseudevernia furfuracea, has substantial commercial value in the perfume industry.
Allocetraria is a genus of lichenized fungi in the family Parmeliaceae. It consists of 12 species, with a center of distribution in China.
Cetrariella is a genus of foliose Northern lichens in the family Parmeliaceae. It contains three species.
Masonhalea is a genus of two species of lichenized fungi in the family Parmeliaceae.
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.
Vulpicida is a genus of lichenized fungi in the family Parmeliaceae. Circumscribed in 1993 to contain species formerly placed in Cetraria, the genus is widespread in Arctic to northern temperate regions, and contains six species. The genus is characterized by the presence of the secondary metabolites pulvinic acid and vulpinic acid, compounds that when combined with usnic acid, give the species their characteristic yellow and green colors.
Tuckermannopsis is a genus of foliose lichens in the family Parmeliaceae.
Myelochroa is a genus of foliose lichens in the family Parmeliaceae. They are commonly known as axil-bristle lichens. It was created in 1987 to contain species formerly placed in genus Parmelina that had a yellow-orange medulla due to the presence of secalonic acids. Characteristics of the genus include tightly attached thalli with narrow lobes, cilia on the axils, and a rhizinate black lower surface. Chemical characteristics are the production of zeorin and related triterpenoids in the medulla. Myelochroa contains about 30 species, most of which grow on bark. The genus has centres of distribution in Asia and North America.
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.
Melanelixia is a genus of foliose lichens in the family Parmeliaceae. It contains 15 Northern Hemisphere species that grow on bark or on wood. The genus is characterized by a pored or fenestrate epicortex, and the production of lecanoric acid as the primary chemical constituent of the medulla. Melanelixia was circumscribed in 2004 as a segregate of the related genus Melanelia.
Cetrelia is a genus of leafy lichens in the large family Parmeliaceae. They are commonly known as sea-storm lichens, alluding to the wavy appearance of their lobes. The name of the genus, circumscribed in 1968 by the husband and wife lichenologists William and Chicita Culberson, alludes to the former placement of these species in the genera Cetraria and Parmelia.
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.
Anzia is a genus of foliose lichens known as black-foam lichens in the large family Parmeliaceae. It was formerly included in the monogeneric family Anziaceae, but this has since been subsumed into the Parmeliaceae.
Bryoria is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. The genus has a widespread distribution, especially in boreal and cool temperate areas.
Esslingeriana is a fungal genus in the family Parmeliaceae. The genus is monotypic, containing the single foliose lichen species Esslingeriana idahoensis, commonly known as the tinted rag lichen. It is found in northwestern North America.
Hypogymnia pseudopruinosa is a species of foliose lichen in the family Parmeliaceae, and one of more than 40 species of the genus Hypogymnia that is found in China. It was formally described by Xinli Wei and Jiangchen Wei in 2006. The type was collected from dead branches of Juniperus sabina, in Degen County (Yunnan), at an altitude of 4,100 metres (13,500 ft). It is quite similar in appearance to Hypogymnia macrospora, but that species lacks the dense layer of pruina that is characteristic of H. pseudopruinosa.
Usnocetraria is a genus of foliose lichens in the family Parmeliaceae.
Parmelia mayi is a species of foliose lichen in the family Parmeliaceae. It is found in the northern Appalachian Mountains of eastern North America, where it grows on rocks and on the trunks of paper birch and balsam fir. Parmelia mayi is morphologically indistinguishable from Parmelia saxatilis, but is distinct in its distribution, chemistry, and genetics.
