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 ...

American Bryological And Lichenological Society
The American Bryological and Lichenological Society is an organization devoted to the scientific study of all aspects of the biology of bryophytes and lichen-forming fungi and is one of the nation's oldest botanical organizations. It was originally known as the Sullivant Moss Society, named after William Starling Sullivant. The Society publishes a quarterly journal distributed worldwide, ''The Bryologist'', which includes articles on all aspects of the biology of mosses, hornworts, liverworts and lichens. The Society also publishes the quarterly journal '' Evansia'', which is intended for both amateurs and professionals in bryology and lichenology and is focused on North America. History The Society was founded in 1898, and was first known as the Sullivant Moss Chapter. It was founded by Elizabeth Gertrude Britton and Abel Joel Grout as a chapter of the Agassiz Association. The organization was established soon after the first publication of ''The Bryologist'', which evolved f ...

Pertusaria Aptrootii
''Pertusaria aptrootii'' is a species of crustose lichen in the family Pertusariaceae. It was species description, described as a new species in 1998 by Alan W. Archer and John Alan Elix. The lichen occurs in Papua New Guinea, and is known from only two specimens collected at the type locality (biology), type locality. The type (biology), type was collected in Varirata National Park at an altitude of , where it was found growing on conglomerate rock. It is named after Dutch lichenologist André Aptroot, who collected the type. The lichen has a dull fawn (colour), fawn, thick, crustose thallus that is cracked and areolate (divided into small, usually rounded to polygonal to irregular areas). It has numerous wart-shaped apothecia that are 1–2 mm in diameter. Between two and four point-like, black ostioles (pore-like openings through which the spores escape) are on each apothecium.

Parmotrema Aptrootii
''Parmotrema aptrootii'' is a species of corticolous lichen in the family Parmeliaceae. Found in South America, it was described as new to science in 1992. The holotype specimen was collected in the Cuyuni-Mazaruni region of Guyana, where it was found growing on a Mahogany tree on the bank of the Kamarang River. It has a pale yellowish to greenish-grey thallus measuring up to about . The specific epithet honours Dutch lichenologist André Aptroot. The lichen has also been recorded from Acre, Brazil, where it is commonly found on dead branches in dense shrubby campinas Campinas (, ''Plains'' or ''Meadows'') is a Brazilian municipality in São Paulo State, part of the country's Southeast Region.

Buellia Aptrootii
''Buellia'' is a genus of mostly lichen-forming fungi in the family Caliciaceae. The fungi are usually part of a crustose lichen. In this case, the lichen species is given the same name as the fungus. But members may also grow as parasites on lichens ( lichenicolous). The algae in the lichen (the photobiont partner) is always a member of the genus ''Trebouxia''. Lichens in the genus are commonly called disc lichens, or button lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The genus has a widespread distribution and contains about 450 species. Genetic studies indicate that the genus '' Amandinea'' and ''Buellia'' may be the same,Scheidegger, C. 2009. Amandinea Choisy ex Scheid. & H. Mayrhofer (1993). In: C. W. Smith, A. Aptroot, B. J.

Aptrootia
''Aptrootia'' is a genus of fungi in the family Trypetheliaceae. It has three species. The genus was circumscribed by Robert Lücking and Harrie Sipman in 2007, with ''Aptrootia terricola'' assigned as the type species. This species, originally described by Dutch mycologist André Aptroot as a species of '' Thelenella'', is known from Papua New Guinea and Costa Rica. Later molecular work showed that the species did not belong in ''Thelenella'' (Aptroot himself had expressed doubt about this generic placement), but rather, in the Trypetheliaceae, with a sister taxon relationship to a branch including ''Bathelium'' and a lineage containing '' Trypethelium floridanum''. The new genus name honours Aptroot, "in recognition of his numerous contributions to tropical lichenology". Species in genus ''Aptrootia'' have completely immersed perithecia with a brown-black ostiolar region. This is surrounded by a white, cartilaginous thallus Thallus (plural: thalli), from Latinized Greek () ...

Eponym
An eponym is a person, a place, or a thing after whom or which someone or something is, or is believed to be, named. The adjectives which are derived from the word eponym include ''eponymous'' and ''eponymic''. Usage of the word The term ''eponym'' functions in multiple related ways, all based on an explicit relationship between two named things. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era. When Henry Ford is referred to as "the ''eponymous'' founder of the Ford Motor Company", his surname "Ford" serves as the eponym. The term also refers to the title character of a fictional work (such as Rocky Balboa of the Rocky film series, ''Rocky'' film series), as well as to ''self-titled'' works named after their creators (such as the album The Doors (album), ''The Doors'' by the band the Doors). Walt Disney created the eponymous The Walt Disney Company, Walt Disney Com ...

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ...
