Jackelixia
''Dufourea'' is a genus of mostly foliose lichen species in the subfamily Xanthorioideae of the family Teloschistaceae. Species in the genus are found in the Southern Hemisphere. Taxonomy The genus was originally circumscription (taxonomy), circumscribed by Swedish lichenologist Erik Acharius in Johann Albert Luyken's 1809 publication ''Tentamen historiae lichenum'', although he did not assign any species to the genus. The following year, Acharius included ''Dufourea'' in his influential work ''Lichenographia Universalis'' and included six species. Luyken had studied under Acharius in Sweden and had access to Acharius's work before it was published; because his text about the genus is a partial transcription of Acharius's work (and he acknowledged Acharius), Acharius is credited as the author of the name as well as the description. All six species that Acharius included in ''Dufourea'' are now classified in different genera. A type species for the genus, ''Dufourea flammea'', was ...

Teloschistaceae
The Teloschistaceae are a large family (biology), family of mostly lichen-forming fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (botany), division Ascomycota. The family has a cosmopolitan distribution, although its members occur predominantly in temperate climate, temperate regions. Most members are lichens that either saxicolous lichen, live on rock or corticolous lichen, on bark, but about 40 species are lichenicolous fungus, lichenicolousmeaning they are non-lichenised fungi that live on other lichens. Many members of the Teloschistaceae are readily identifiable by their vibrant orange to yellow hue, a result of their frequent anthraquinone content. The presence of these anthraquinone biological pigment, pigments, which confer protection from ultraviolet light, enabled this group to expand from shaded forest habitats to harsher environmental conditions of sunny and arid ecosystems during the Late Cretaceous. Teloschistaceae lichens typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dufourea Ligulata
''Dufourea ligulata'' is a species of saxicolous (rock-dwelling), foliose lichen in the family Teloschistaceae. The German lichenologist Gustav Wilhelm Körber first formally described the species in 1862, as a member of the genus ''Physcia''. Patrik Frödén, Ulf Arup, and Ulrik Søchting transferred it to the genus '' Dufourea'' in 2013 as part of a molecular phylogenetics-based restructuring of the family Teloschistaceae. The lichen is found in Australasia, usually on coastal rocks. The of its thallus Thallus (: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. A thallus usually names the entir ... are 5–10 mm long; they are generally longer and narrower than those of other Australian lichens, including '' X. streimannii'', '' X. parietina'', '' X. filsonii'', and '' X. elixii''.

Dufourea Angustata
''Dufourea angustata'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed across Australia. Taxonomy The lichen was formally described in 2009 by the lichenologists Sergey Kondratyuk and Ingvar Kärnefelt; they initially placed it as a member of genus '' Xanthoria''. The type specimen was collected by the authors from rocky outcrops south of Batemans Bay in New South Wales. The species epithet ''angustata'', derived from the Latin ("narrow"), alludes to the shape of the thallus . Description ''Dufourea angustata'' is a lichen that typically forms a reddish-orange to brick orange thallus, spanning 2–3 cm in width. It features narrow and distinct that often interconnect to form a net-like pattern. These lobes are usually 0.4–1 (up to 1.2) mm wide and 5–6 mm long, with frequent and irregular branching. Including the secondary , the lobes can reach up to 3.5 mm in width. The apothecia of ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dufourea Flammea
''Dufourea'' is a genus of Halictidae, sweat bees in the family Halictidae. There are at least 160 described species in ''Dufourea''.Sharkey M.J. (2007). ''Phylogeny and Classification of Hymenoptera''."Phylogenetic relationships among superfamilies of Hymenoptera", Sharkey M.J., Carpenter J.M., Vilhelmsen L., et al. 2012. ''Cladistics'' 28(1): 80-112. The bees are very uncommon. The bases of their antennae are well below the middle of their face and are only separated from the Clypeus (arthropod anatomy), clypeus on the bottom of the face by not much more than the diameter of an antennal socket. The clypeus is short and wide, and the Labrum (arthropod mouthpart), labrum is nearly as long as the clypeus. The species features a pre-Pleuron (insect anatomy), episternal groove.

Dufourea Africana
''Dufourea africana'' is a species of corticolous (bark-dwelling), foliose lichen in the family Teloschistaceae. It occurs in Kenya and Uganda. Taxonomy The lichen was first described by the Swedish lichenologist Ove Almborn in 1963, who classified it in the genus '' Xanthoria''. The type specimen was collected in 1949 by the Dutch mycologist Rudolf Arnold Maas Geesteranus from the Tinderer Forest Reserve in Kisumu-Londiani (Kenya) at an elevation of ; there, it was found growing on an isolated and sun-exposed ''Podocarpus milanjianus''. Patrik Frödén and colleagues transferred the taxon to the genus '' Dufourea'' in 2013, following a molecular phylogenetics-led reorganisation of the Teloschistaceae. Description The lichen has an orange thallus that usually spreads irregularly on its , with up to 1 mm wide. The thallus surface has regions of soralia that are both and , and makes orange-coloured soredia; apothecia (fruiting bodies) have not been observed to occur in t ...
