Vigneronia
''Vigneronia'' is a genus of lichen-forming fungi in the family Roccellaceae. It has five species. The genus was circumscription (taxonomy), circumscribed in 2014 by Damien Ernst, with ''Vigneronia spieri'' assigned as the type species. This species, originally species description, described as ''Schismatomma spieri'' from collections made in the Galápagos Islands, has since been recorded from mainland Ecuador and the Antilles (Curaçao). The genus is named after Ernst's wife, Nathalie Vigneron, who accompanied him on collecting trips. ''Vigneronia'' lichens are crustose lichen, crustose, and have a smooth, thin, thallus lacking a cortex (botany), cortex. The photobiont partner is Trentepohlia (alga), trentepohlioid. Lichen products identified from members of the genus include roccellic acid, erythrin, and gyrophoric acid. The ascomata are in the form of elongated, measuring 0.5–4 by 0.3–1 mm in diameter.

Vigneronia Spieri
''Vigneronia spieri'' is a species of corticolous (bark-dwelling), crustose lichen in the family Roccellaceae. It is found in the Galápagos Islands, mainland Ecuador and the Antilles (Curaçao). Taxonomy The lichen was first described scientifically by lichenologists André Aptroot and Laurens Sparrius in 2008, as a member of the genus ''Schismatomma''. The type specimen was collected by the first author from Cerro Alcedo on Isabela Island (Galápagos) at an altitude of ; there, in an area of dry lowlands with basalt outcrops, it was found growing on the bark of '' Bursera graveolens''. The lichen has also been recorded from Santa Cruz and Santiago islands. The species epithet honours Dutch lichenologist Leo Spier, who assisted the authors with thin-layer chromatography of lichen specimens. In 2014, following a large-scale phylogenetic revision of the Roccellaceae, Damien Ertz transferred the taxon to the newly circumscribed genus ''Vigneronia'', in which it is th ...

André Aptroot
André Aptroot (Heemskerk, 1961) is a Dutch mycologist and lichenologist. In 1993 he did his PhD at the University of Utrecht under the supervision of Robbert Gradstein (nl). His dissertation was titled "Systematic studies on pyrenocarpous lichens and related fungi". He specializes in fungi and lichens on which he has several hundreds of publications to his name. He has worked as curator at Centraalbureau voor Schimmelcultures (now Westerdijk Institute). Aptroot is the founder of the Consultancy for Bryology and Lichenology, which is located in Soest where there is a herbarium with a collection of lichens mainly from the Netherlands and the tropics. From 2008 he has been collection manager at Pinetum Blijdenstein (nl) in Hilversum. He is a member of the International Association for Lichenology and the American Bryological and Lichenological Society. He is a visiting professor at the Federal University of Mato Grosso do Sul in Campo Grande, Brazil. Because of Aptroot's bro ...

Lichen Product
Lichen products, also known as lichen substances, are organic compounds produced by a lichen. Specifically, they are secondary metabolites. Lichen products are represented in several different chemical classes, including terpenoids, orcinol derivatives, chromones, xanthones, depsides, and depsidones. Over 800 lichen products of known chemical structure have been reported in the scientific literature, and most of these compound are exclusively found in lichens. Examples of lichen products include usnic acid (a dibenzofuran), atranorin (a depside), lichexanthone (a xanthone), salazinic acid (a depsidone), and isolichenan, an α-glucan. Many lichen products have biological activity, and research into these effects is ongoing. Lichen products accumulate on the outer walls of the fungal hyphae, and are quite stable. Crystal deposits can be visualised using scanning electron microscopy. For this reason, even very old herbarium specimens can be analysed. The amount of lichen products i ...

Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean.

The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville. Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first k ...
