Coenogonium implexum is a yellow-green byssoid lichen with light orange apothecia found in Australia. [2] It is in the family Coenogoniaceae, and was first described by William Nylander in 1862. [3]
William (Wilhem) Nylander was a Finnish botanist and entomologist. Nylander was born in Oulu, and taught at the University of Helsinki before moving to Paris, where he lived until his death in 1899.
Gyalectales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 5 families, 15 genera and about 550 species.
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.
Lyromma is a genus of foliicolous (leaf-dwelling) lichens, and the sole member of Lyrommataceae, a family in the order Chaetothyriales. The genus was circumscribed in 1965 by Brazilian mycologists Augusto Chaves Batista and Heraldo da Silva Maia, with Lyromma nectandrae assigned as the type species. The family was proposed by Robert Lücking in 2008. Characteristics of the genus include the spherical to short barrel-shaped perithecia and elongated barrel-shaped pycnidia, and smooth thalli of rounded patches formed by its symbiotic relationship with green algae from the genus Phycopeltis.
Tylophoron is a genus of lichen-forming fungi in the family Arthoniaceae. The genus was circumscribed in 1862 by Finnish lichenologist William Nylander.
Dactylina is a genus of lichen-forming fungi in the family Parmeliaceae. The genus was circumscribed by Finnish botanist William Nylander in 1860, with Dactylina arctica assigned as the type species.
A byssoid lichen is a lichen with a wispy growth form, having the appearance of teased wool. Coenogonium implexum is a byssoid lichen.
A spot test in lichenology is a spot analysis used to help identify lichens. It is performed by placing a drop of a chemical on different parts of the lichen and noting the colour change associated with application of the chemical. The tests are routinely encountered in dichotomous keys for lichen species, and they take advantage of the wide array of lichen products produced by lichens and their uniqueness among taxa. As such, spot tests reveal the presence or absence of chemicals in various parts of a lichen. They were first proposed by the botanist William Nylander in 1866.
Vermilacinia robusta is an olive green fruticose lichen that occurs on rocks near ocean mist along the foggy Pacific Coast of southern California to northern Baja California and offshore islands. The epithet, robusta, was probably adopted in recognizing a more robust form of V. comboides, originally described as a variety of Ramalina combeoides by R. Heber Howe, Jr. in 1913.
Vermilacinia flaccescens is a fruticose lichen that grows on cacti and shrubs in the fog regions along the Pacific Coast of South America, Peru, Chile and in the Juan Fernandez Islands The epithet is in reference to the flaccid thallus but some specimens have been interpreted to have rigid branches.
Usnea scabrida is a foliose lichen that grows from holdfasts on trees. It occurs in southwest Western Australia. It is a very pale grayish-yellowish green, slender, pendant, branching from the base, unequally branching, and shrubby. The cortex contains usnic acid, and the medulla contains scabrosins. The lichen was described as a new species in 1844 by English botanist Thomas Taylor.
Rev. James Mascall Morrison Crombie was a Scottish lichenologist. The standard author abbreviation Cromb. is used to indicate this person as the author when citing a botanical name.
Edvard August Vainio was a Finnish lichenologist. His early works on the lichens of Lapland, his three-volume monograph on the lichen genus Cladonia, and, in particular, his study of the classification and form and structure of lichens in Brazil, made Vainio renowned internationally in the field of lichenology.
Melanohalea subolivacea, commonly known as the brown-eyed camouflage lichen, is a species of foliose lichen in the family Parmeliaceae.
Punctelia hypoleucites, commonly known as the southwestern speckled shield lichen, is a species of foliose (leafy) lichen in the family Parmeliaceae. First formally described by Finnish botanist William Nylander as a species of Parmelia, it was transferred to the genus Punctelia in 1982. The lichen is found in Africa, North America, and South America, where it grows on the bark of both hardwood and coniferous trees. Its greenish-grey thallus is covered with tiny white pseudocyphellae – minute holes in the thallus surface that facilitate gas exchange. Some macroscopic features that help distinguish this species from other related members of the genus include the presence and the structure of the apothecia, the absence of asexual surface propagules, and the light brown color of the thallus undersurface. Chemically, the presence of lecanoric acid in the medulla and atranorin in the cortex help distinguish it from lookalikes.
Johan Petter Norrlin was a Finnish botanist and a professor of botany at the University of Helsinki from 1879 to 1903. He was a pioneer of plant geography in Finland, and is also well known for his work on lichens and on the taxonomy of the apomictic taxa of the plant genera Hieracium and Pilosella.
Rockefellera is a fungal genus in the family Pannariaceae. It is a monotypic genus, containing the single species Rockefellera crossophylla. The genus was circumscribed by James Lendemer and Erin Tripp in 2017. The generic name honors the Rockefeller family, "for their century-long support of North American conservation efforts, particularly with respect to national parks."
Xanthoparmelia semiviridis, also known as resurrection lichen is a foliose lichen species in the family Parmeliaceae. Its common name comes from the reaction of a dry sample to moisture. In its dry state it appears like curled-up dry leaf litter on the ground, but after rainfall the lichen will quickly recover, unfurl and become darker in colour. It is found in semi-arid areas across southern Australia and the South Island of New Zealand. The species is in decline in New Zealand because of the loss of habitat resulting from the establishment of dairy farms and vineyards in former indigenous habitat, and the deterioration of existing habitat caused by invasive species such as hawkweeds.
Coenogonium pineti is a species of crustose lichen in the family Coenogoniaceae. It was first formally described by Erik Acharius in 1810, as Lecidea pineti. Robert Lücking and H. Thorsten Lumbsch transferred it to Coenogonium in 2004 after molecular phylogenetic analysis suggested its placement in that genus. The lichen has a widespread distribution in cooler, temperate regions of the Northern Hemisphere, but has also been recorded from southeastern mainland Australia and Tasmania.
