Oxneria Ussuriensis
''Oxneria ussuriensis'' is a species of corticolous, crustose lichen in the family Teloschistaceae. It is found in a single location in the Russian Far East. Taxonomy The lichen was formally described as a new species in 2014 by lichenologists Sergey Kondratyuk, Soon-Ok Oh, and Jae-Seoun Hur. The type specimen was collected by the first author from a park in Kraskino (in the Khasansky District of Primorsky Krai), where he found it growing on a ''Populus'' tree. The species epithet refers to the type locality. Description ''Oxneria ussuriensis'' has a deep orange to orange-yellow rosette-like thallus that has a diameter of . The individual lobes comprising the thallus are 1.5–2 mm long, and have a width that ranges from 0.3–0.7 mm in the narrowest parts to 1 mm in the widest parts. The terminal parts of the lobes sometimes branch out to form secondary lobes or lobules. The underside of the lobes are covered with bluish-greyish soredia. Individual soredia a ...

Alfred Oxner
Alfred Mycolayovych Oxner ( uk, Альфред Миколайович Окснер; russian: Альфре́д Никола́евич О́кснер) (15 February 1898 – 20 November 1973) was a Ukrainian botanist and lichenologist. His research covered various areas: floristics, taxonomy, phylogenetics, phytogeography, and phytosociology. Oxner founded the National Lichenological Herbarium of Ukraine. Biography Alfred Nikolaevich Oxner was born on 15 February 1898 in Elizavetgrad (now Kropyvnytskyi, Ukraine). Although his family was of German nobility, they kept their origins and nationality secret during the time of the former socialist regime. The names of his real parents, Nicolay Ochsner, an ensign in the reserve and a farmer, and his mother Wilgelmine (née Schwartz), are on his birth certificate. However, he grew up with the families of his foster mother Zinaida Lazarevna Solomonova and her brother Mozyrj Lazarevich Solomonov. In 1917, after graduating from the Elisavet ...

Oxneria Fallax
''Oxneria fallax'', also known as the hooded sunburst lichen, is a small yellow-orange to red-orange foliose lichen that grows on bark or rarely on rock or bone. It is found all over the world except very dry areas, with 10 species common in North America.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichen Flora of the Greater Sonoran Desert Region. Vol 2, Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref> The nonfruiting body (thallus) grows in rosettes to 3 cm in diameter. The rosettes sometimes coalesce with each other. The lobes may appear divided at the tips. It is sometimes tightly appressed to the substrate (adnate), and sometimes not. The fruiting bodies (apothecia) are lecanorine, meaning that they are disc-like with a ring or rim of tissue around the disc that is made of tissue similar to the thallus. The tips of the lobes form hood shaped soralia that produce powdery greenish yellow soredia Soredia are common repr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teloschistaceae
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family, estimated to contain over 1800 species, was extensively revised in 2013, including the creation or resurrection of 31 genera. It contains three subfamilies: Xanthorioideae, Caloplacoideae, and Teloschistoideae. A fourth subfamily, Brownlielloideae, proposed in 2015, has been shown to be part of the Teloschistoideae. Genera This is a list of the genera contained within the Teloschistaceae, based on a 2020 review and summary of ascomycete classification. Following the genus name is the taxonomic authority, year of publication, and the number of species: *'' Amundsenia'' – 2 spp. *'' Andina'' - 1 sp. *'' Apatoplaca'' – 1 sp. *'' Aridoplaca'' - 1 sp. *'' Athallia'' – 17 spp. *'' Austroplaca'' – 10 spp. *'' Blastenia'' – 11 spp. *'' Brownliella'' – 4 spp. *'' Bryoplaca'' – 3 spp. *'' Calogaya'' – 19 spp. *'' Calop ...

Sergey Kondratyuk
Sergey Yakovlevich Kondratyuk ( uk, Сергій Якович Кондратюк) (born 17 May 1959) is a Ukrainian botanist specialising in lichenology. His research deals with the taxonomy, floristics, ecology and geography of lichens and lichenicolous fungi. He has worked at the for more than 40 years. In 2014 Kondratyuk was awarded the State Prize of Ukraine in Science and Technology. Early life and education Kondratyuk was born in the Kirovohrad region, in Ulyanovsk. After graduating from school in 1976 he became a student of the Faculty of Biology at Kyiv State University. He specialized in the Department of Lower Plants. While still a student, Kondratyuk started to study lichens under the guidance of O.B. Bloom. Then began his career at the Institute of Botany (1979), as a senior technician and later an engineer in the Department of Algology and Lichenology. He continued his career as a graduate student of the institute (1981–1984). After successfully defending his d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ingvar Kärnefelt
Jan Eric Ingvar Kärnefelt (born 1944) is a Swedish lichenologist. Early life and education Kärnefelt was born in Gothenburg, Sweden in 1944. His initial goal in his higher-level studies at University of Cologne in 1966–1967 was to become a dentist. He changed courses in 1968, turning instead to biology at the University of Gothenburg in 1968. Gunnar Degelius, his first teacher during undergraduate studies in botany in 1968, inspired him and others. After Degelius' retirement in 1969, Ingvar continued his studies at Lund University, where Hans Runemark held a position in systematic botany. In 1971 he met Ove Almborn, who became his supervisor. In 1979, he defended his thesis titled "The brown fruticose species of ''Cetraria''". The thesis was later awarded a prize for the best doctoral dissertation in botany at Lund University during a 5-year period by the Royal Physiographic Society in Lund.

Taxa Described In 2003
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 system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lecanoromycetes Genera
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence. Genera of uncertain placement The are several genera in the Lecanoromycetes that have not been placed into any order or family.
