Biography

Lumbsch was born in Frankfurt in 1964. Interested in lichens already as a schoolboy, he studied natural sciences at the University of Marburg, under the tutelage of Aino Henssen. He received his diploma in 1989, with a dissertation titled Ontogenetisch-systematische Studien der Trapeliaceae und verwandter Familien (Lichenisierte Ascomyceten) ("Ontogenic-systematic studies of the Trapeliaceae and related families (lichenized ascomycetes"). After Henssen's retirement in 1990, he transferred to the University in Essen, where he worked on the Lecanora subfusca group in Australasia, a subject that was the topic of his PhD dissertation. In 1993 he completed his doctorate under the supervision of Guido Benno Feige. [2]

Between 1994 and 1997, Lumbsch did postdoctoral research at the Botanical Garden of the University of Duisburg-Essen; in 1998–2003 he was a private lecturer there. Between 2003 and 2006 he was the Assistant curator at the Field Museum of Natural History. Since 2004, Lumbsch has been a member of committee on Evolutionary Biology at the University of Chicago, an interdepartmental and inter-institutional graduate student training program. In the years 2005–2009 he was the head of Cryptogams at the Field Museum, and between 2006 and 2014, the Associate Curator. [2] Lumbsch was the president of the International Association for Lichenology in the years 2012–2016. [3]

Lumbsch has been the author or coauthor of more than 500 publications, many of which deal with molecular phylogenetics of various taxa of lichens. [2] In his 2009 survey of influential lichenologists, Ingvar Kärnefelt calls him "a leading scientist on systematics and evolution of lichenized fungi." [4]

Eponymy

Several lichen species have been named in honour of Lumbsch, including: [2] Paraparmelia lumbschii Elix (1996); [5] Graphina lumbschii A.W.Archer (2001); [6] Sticta lumbschiana Moncada & Lücking (2013); [7] Fissurina lumbschiana Weerakoon, Jayalal & Lücking (2015); [8] Ocellularia lumbschii S.Joshi & Hur (2015); [9] and Pertusaria lumbschii A.W.Archer & Elix (2017).

The Peltigeraceae are a family of lichens in the order Peltigerales. The Peltigeraceae, which contains 15 genera and about 600 species, has recently (2018) been emended to include the families Lobariaceae and Nephromataceae. Many Peltigeraceae species have large and conspicuous, leathery thalli. They largely occur in cool-temperate to tropical montane climates. Tripartite thalli involving fungus, green algae and cyanobacteria are common in this family.

Salazinic acid is a depsidone with a lactone ring. It is found in some lichens, and is especially prevalent in Parmotrema and Bulbothrix, where its presence or absence is often used to help classify species in those genera.

Ocellularia aptrootiana is a species of corticolous lichen in the family Graphidaceae. Found in Sri Lanka, it was formally described as a new species in 2014 by lichenologists Gothamie Weerakoon, Robert Lücking, and Helge Thorsten Lumbsch. The type specimen was collected from Mahailluppallama at an altitude of 170 m (560 ft). Here, in a low-altitude, dry, semi-evergreen forest, it was found growing around a water tank. The specific epithet aptrootiana honours Dutch lichenologist André Aptroot, "for his important contributions to tropical lichenology and his help with the research by the first author". Ocellularia aptrootiana has a grey, smooth to uneven or cracked thallus up to convert 5 cm (2 in) in diameter. The ascospores are hyaline, ellipsoid in shape, contain seven septa, and measure 20–25 by 6–7 μm. Secondary chemicals present in the lichen include psoromic acid, subpsoromic acid, and 2’-O-demethylpsoromic acids.

Ocellularia cloonanii is a species of corticolous lichen in the family Graphidaceae. Found in Sri Lanka, it was formally described as a new species in 2014 by lichenologists Gothamie Weerakoon, Robert Lücking, and Helge Thorsten Lumbsch. The type specimen was collected from a high-elevation montane forest in the Fishing Hut Tea Estate at an altitude of 1,870 m (6,140 ft). The lichen is only known to occur at the type locality in the Horton Plains. The specific epithet cloonanii honours Colman Patrick Cloonan, "for his immense help in carrying out the research studies". Ocellularia cloonanii has an olive-grey thallus up to 5 cm (2 in) in diameter, with continuous but uneven surface. Its ascospores are hyaline, ellipsoid in shape, contain seven to nine septa, and measure 35–40 by 7–10 μm. Secondary chemicals present in the lichen include psoromic acid, subpsoromic acid, and 2’-O-demethylpsoromic acid.

Ocellularia raveniana is a species of corticolous lichen in the family Graphidaceae. Found in Sri Lanka, it was formally described as a new species in 2014 by lichenologists Gothamie Weerakoon, Robert Lücking, and Helge Thorsten Lumbsch. The type specimen was collected from a high-elevation tea estate in Matale at an altitude of 1,360 m (4,460 ft). The lichen is only known to occur at the type locality and in the Sabaragamuwa Mountain Range. The specific epithet raveniana honours botanist and environmentalist Peter H. Raven, longtime director and now President Emeritus of the Missouri Botanical Garden. Ocellularia raveniana has a cream-colored to white thallus up to 10 cm (4 in) in diameter, with an uneven to somewhat verrucose (warty) surface. Its ascospores are hyaline, oblong to ellipsoid in shape, contain seven to nine septa, and measure 25–35 by 8–10 μm. Secondary chemicals present in the lichen include protocetraric acid, and virensic acid.
