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. [2]
The genus name of Anzia is in honour of Martino Anzi (1812-1883), an Italian botanist and professor of theology from Como. [3]
The genus was circumscribed by Ernst Stizenberger in 1862, with Anzia colpodes assigned as the type species. [4] This lichen was originally described as Lichen colpodes by Erik Acharius in 1799. [5]
In 1932, Yasuhiko Asahina divided the genus into three sections (Simplices, Duplices, and Nervosae) based on the structure of the medulla. [6] When Isao Yoshimura later observed that Anzia japonica had two medulla types in a single species (i.e. both a single-layered and a double-layered medulla), he combined sections Simplices and Duplices into section Anziae. [7]
Members of Anzia have a foliose growth form, with a thallus that can measure anywhere from 2–30 cm (0.8–11.8 in) wide. The narrow lobes that comprise the thallus are pale greyish white to greyish green in colour. It is one of the only groups in the family not to have eight spores in each ascus, but instead has numerous spores in each ascus (varying slightly from ascus to ascus). These ascospores are crescent shaped. A characteristic of the genus is the presence of a brown-black or pale brown spongy cushion called a spongiostratum, which covers the lower surface. [8]
Pannoparmelia also has a spongiostratum, but in this genus the asci contain eight ascospores, and the upper cortex is yellow-green. [8]
The genus has a cosmopolitan distribution, but is concentrated in the Northern Hemisphere, particularly in Japan. [9]
A fossilized Anzia, Anzia electra , was found in 35–40 Myr-old Baltic amber. Its features suggest that the main distinguishing characteristics in the thallus morphology of section Anzia have been retained for tens of millions of years. [10]
Parmelia is a genus of medium to large foliose lichens. It has a global distribution, extending from the Arctic to the Antarctic continent but concentrated in temperate regions. There are about 40 species in Parmelia. In recent decades, the once large genus Parmelia has been divided into a number of smaller genera according to thallus morphology and phylogenetic relatedness.
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.
Lobaria is a genus of foliose lichens, formerly classified in the family Lobariaceae, but now placed in the Peltigeraceae. They are commonly known as "lung wort" or "lungmoss" as their physical shape somewhat resembles a lung, and their ecological niche is similar to that of moss.
Phyllopsora is a genus of lichenized fungi in the family Ramalinaceae. It was circumscribed by Swiss botanist Johannes Müller Argoviensis in 1894.
Enterographa is a genus of lichens in the family Roccellaceae.
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. Other common characteristics are relatively small spores and the presence of physodic acid and related lichen products. The lichens usually grow on the bark and wood of coniferous trees.
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.
Canoparmelia is a genus of lichen-forming fungi in the family Parmeliaceae. The widespread genus contains about 35 species. Canoparmelia, a segregate of the parmelioid lichen genus Pseudoparmelia, was circumscribed by John Elix and Mason Hale in 1986.
Bulbothrix is a genus of lichen-forming fungi in the family Parmeliaceae. This genus is synonymous with Bulbothricella V.Marcano, S.Mohali & A.Morales. Bulbothrix was circumscribed by lichenologist Mason E. Hale in 1974 with Bulbothrix semilunata as the type species.
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 mahaeliyensis is a species of lichenised ascomycete of the genus Anzia in the large family Parmeliaceae. It is endemic to Sri Lanka. The species is characterized by white, single-layered medulla and pale-tipped isidia.
Anzia flavotenuis is a species of lichenised ascomycete of the genus Anzia in the large family Parmeliaceae. It is endemic to Sri Lanka. The species is characterized by two-layered medulla with a yellow upper layer and white lower layer. The isidia have brown-black tips.
Myelochroa salazinica is a species of foliose lichen in the family Parmeliaceae. Found in China, it was described as a new species in 2001 by Sheng-Lan Wang, Jian-Bin Chen, and John Alan Elix.
Herpothallon is a genus of crustose lichens in the family Arthoniaceae. It has about 50 species.
Anzia pseudocolpota is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. Found in southwestern China, it was formally described as a new species in 2015 by Xin-Yu Wang and Li-Song Wang. The type specimen was collected by the second author from Lidiping mountain at an altitude of 3,350 m (10,990 ft), where it was found growing on Loranthus bark. It is named for its similarity to Anzia colpota, from which it differs by the presence of a central axis, a discontinuous spongiostratum, and the presence of the lichen product divaricatic acid. The lichen is only known to occur in Sichuan and Yunnan, at elevation ranges between 2,500 and 3,700 m.
