Palicella is a genus of crustose lichens in the family Lecanoraceae. [1] It contains six species.
The genus was circumscribed in 2014 by lichenologists Pamela Rodriguez-De Flakus and Christian Printzen to accommodate the type species, Palicella glaucopa (formerly placed in the genus Lecidea ), and two closely related species, P. filamentosa and P. schizochromatica. Molecular analyses of these lichens revealed a monophyletic clade that is sister to representatives from two Lecanoraceae genera, Lecanora symmicta and Pyrrhospora quernea . [2] Two additional species were transferred to Palicella from Lecanora in 2019. [3] [4]
Palicella species have biatorine apothecia, which are often darkened (by the pigment known as Cinereorufa-green ), an exciple (a saucer-shaped rim around the hymenium) consisting of radiating, narrow hyphae with elongated lumina, and a hymenium with branched and sparsely anastomosed paraphyses. Other microscopic characteristics include an ascus with a broad axial body surrounded by a distinct darker staining layer, and ascospores with a narrow ellipsoid shape. [2]
As of March 2023 [update] , Species Fungorum (as listed in the Catalogue of Life) accepts six species in Palicella: [5]
The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Biatora is a genus of lichens in the family Ramalinaceae. First described in 1817, the genus consists of crustose and squamulose lichens with green algal photobionts, biatorine apothecia, colorless, simple to 3-septate ascospores, and bacilliform pycnospores. According to the Dictionary of the Fungi, the genus contains 42 species that are widely distributed in temperate areas.
Vainionora is a genus of lichen in the family Lecanoraceae. The genus, which was circumscribed in 1991 by German lichenologist Klaus Kalb, honours the Finnish lichenologist Edvard Vainio, who described the type species as Lecanora pallidostraminea in 1890.
Absconditella is a genus of lichenised fungi in the family Stictidaceae. The genus was circumscribed in 1965 by Czech lichenologist Antonín Vězda, with Absconditella sphagnorum assigned as the type species. Absconditella is characterised by gyalectoid apothecia with a hymenium that is not amyloid, without a dark pigment and thalli containing green algae as photobionts. The genus name means "hidden", a reference to the scant structure of the thallus and its small apothecia.
Fuscidea is a genus of crustose lichens in the family Fuscideaceae. It has about 40 species. The genus was circumscribed in 1972 by lichenologists Volkmar Wirth and Antonín Vězda, with Fuscidea aggregatilis assigned as the type species.
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species.
Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".
Scoliciosporum is a genus of lichens in the family Scoliciosporaceae.
Bryobilimbia is a genus of lichen-forming fungi belonging to the family Lecideaceae. It was circumscribed in 2014 by Alan Fryday, Christian Printzen, and Stefan Ekman. The type species is Bryolimbia hypnorum.
Sedelnikovaea is a genus of placodioid lichens in the family Lecanoraceae. The genus was circumscribed in 2015 by Sergey Kondratyuk, Min-Hye Jeong, and Jae-Seoun Hur to contain Sedelnikovaea baicalensis, the type species. Three additional species were transferred into the genus in 2019.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Zhurbenkoa is a genus of lichenicolous fungi in the family Malmideaceae. It has three species. The genus was circumscribed in 2019 by Adam Flakus, Javier Etayo, Sergio Pérez-Ortega, and Pamela Rodriguez-Flakus, with Zhurbenkoa epicladonia assigned as the type species. Closely related genera are Savoronala and Sprucidea. The generic name honours Russian lichenologist Mikhail Zhurbenko, "for his magnificent contribution to knowledge on the biodiversity and systematics of lichenicolous fungi, including lichen parasites colonizing Cladonia".
Lecidella mandshurica is a species of corticolous (bark-dwelling), crustose lichen in the family Lecanoraceae. It is found in the Russian Far East, South Korea, and China.
Biatora oxneri is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. It is found in the Russian Far East and in South Korea.
Verseghya is a genus of lichen-forming fungi in the family Pertusariaceae. It has two species. The genus was circumscribed in 2016 by lichenologists Sergey Kondratyuk, Laszlo Lőkös, and Jae-Seoun Hur, with Verseghya klarae assigned as the type species. This crustose species is found in South Korea, where it grows on the bark of a wide variety of both deciduous and coniferous trees. Molecular phylogenetic analysis showed that Verseghya klarae occupied a separate phylogenetic branch in the Pertusariaceae, situated between the genera Ochrolechia and Pertusaria and the Lecanora subcarnea species complex. Verseghya thysanophora was transferred to the genus in 2019. It is widely distributed in the Northern Hemisphere.
Robert Lücking is a German lichenologist. He earned his master's and PhD from the University of Ulm, focusing on the taxonomy, ecology, and biodiversity of foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale Award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in The Bryologist. Since 2015, he has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum, and several lichen species and a genus have been named in his honour.
Palicella lueckingii is a species of corticolous (bark-dwelling) lecideoid lichen in the family Lecanoraceae. Found in Chile, it was formally described as a new species in 2018 by Pamela Rodriguez-Flakus. The type specimen was collected from the Malalcahuelo National Reserve, where it was found growing on the bark of Araucaria araucana in Valdivian temperate rain forest. It is only known to occur at the type locality. The species epithet honours German lichenologist Robert Lücking, "who has made an outstanding contribution to the knowledge of Neotropical lichens".
Verseghya thysanophora, commonly known as the mapledust lichen, is a species of mostly corticolous (bark-dwelling), leprose lichen in the family Pertusariaceae. This common species is widely distributed in the Northern Hemisphere. The thallus of the lichen is a thin patchy layer of granular soredia, pale green to yellowish green in colour. The main characteristics of the lichen include the presence of lichen products known as thysanophora unknowns, and the conspicuous white, fibrous prothallus that encircles the thallus.
